Resurrection: 1998 Belgian Procar - Thierry Tassin ELR/Honda/Foss-Tech #7 race car

Post by Rboosted717 » Sun Aug 13, 2017 3:05 pm

I'll be using this thread to document the history and restoration process of this amazing and historically significant race car. Below is a YouTube link to a compilation of video clips from the 1998 Belgian Procar series where this car won the manufactures title for Honda. This is very important as it demonstrated Honda's ability to be a champion in the highly competitive European touring car market.

Part 1 – “Why this car matters: The History, Race Results, and Prior Ownership”

This car was part of a batch of the “Body in White” Integra Type R that was sold directly by Honda Motorsport Europe (Honda Racing Europe) to Foss-Tech (York) Precision Fabrication & Engineering Services Inc. in Harrogate/ North Yorkshire, England, in late 1997 to be prepared for racing purposes under the FIA Super Production specifications for the 1998 Belgian Procar series.



Honda’s “Body In White” program is unique; it gives race teams and chassis fabricators a stripped-down primered vehicle shell that can be modified to exact personal specifications. The chassis is also a lighter platform to start with, as it lacks heavy rust inhibitors (zinc plating), seam sealers, adhesives, sound-deadening material, crash beams, and other items found in a standard production vehicle. This particular car has the Body in White chassis number ST7-0003014. The Realtime Racing cars and a handful of other factory-supported race teams have similar and sequential chassis numbers. 



European touring car racing has a long history of competition that draws enormous crowds and sparks manufacturer- and model-specific cult-like followings. Such racing series with the BMW (M3, 320i, E30, E36), Renault (Megane), Peugeot (306), Mercedes (190E), Audi, and VW, to name a few, have produced some of the most iconic models that we’ve come to cherish. Outside of the NSX and Accord, Honda had mostly been absent from the European/FIA Group N specification racing series. However, in light of the 1996–1997 popularity of the Integra Type R in Japan, Honda wanted to introduce the car to the European market in 1998.



To make a major footprint in the European touring car scene, Honda selected the infamous Belgian Procar series, intending to set as many track records as possible and clinch the manufacturers’ (constructors’) championship in 1998. The goal couldn’t have been set higher, but Honda had all the right people in place to make it achievable. This effort was primarily led by William De Braekeleer, Head of Honda Motor Europe, David Thomson of Foss-Tech, and Marc Vanderghen of European Luigi Racing (ELR), along with a handful of other fabrication shops and race teams. Foss-Tech handled the chassis fabrication and ELR the race car setup, engine tuning, and race strategy. 



Foss-Tech placed the Body in White chassis on a rotisserie, fully seam welded it inside and out, and built a highly customized roll cage made from T45 steel (similar to chromoly). T45 is a unique and special alloy that has a tensile strength approximately twice that of the standard Cold Drawn Seamless (CDS; aka mild steel), meaning that the roll cage could be built with tubing of the same diameter but of a thinner gauge (wall thickness) for additional weight reduction. This equates to a weight savings of approximately 1/3 pound per foot of tubing, or 10–15% of the total roll cage weight, when compared to CDS. T45 is typically used in aerospace and high-end racing applications because of its high cost, scarcity, and demand for specific preparation and welding techniques. The multipoint roll cage features a custom rear strut tower and wheel well reinforcements, center subframe brace, rocker sill bars, driver seat support, gusseted door impact X-braces, six-point dash/firewall bracing, and a three-point front strut tower triangulation. Nearly every weld point is gusseted and attached to the body where possible. The cage also incorporates four-point air jacks, fuel cell supports, and attachment points for the dash, rearview mirror, and other accessories.



Foss-Tech also modified the rear suspension pick-up points for a better roll center, boxed the rear trailing arms, rear upper and lower arms, and rear toe links, and replaced all bushings with custom offset spherical versions to increase camber to upwards of -5 degrees and caster by +2 degrees. For the anti-roll bars, Foss-Tech fabricated a three-piece system for the rear that can attach to either the lower arm (factory style) or the trailing arm (near the upper arm connection point) for increased effectiveness. For the front, they created a three-piece system that mounts to the lower subframe and connects to the lower arms in a similar manner to the factory setup. The two systems are fully adjustable, with three stiffness settings, interchangeable hollow and solid main bars, and tubular or blade-style arms. For the actual suspension, Foss-Tech equipped the car with a three-way Penske setup that uses external reservoirs on each corner and features unique mounting hats to maximize the pivot angle and decrease suspension/coil bind. Because of the modified roll center, it was possible to utilize softer springs to increase overall stability.



Custom-fabricated four-point AP Racing front brakes were equipped with custom carbon fiber ducting to cool the caliper and pads, rotor and hat, and outer CV joint. The transmission and inner CV joints also feature custom carbon fiber ducting for additional cooling. The car has lightweight 15x7 magnesium Technomagnesio Racing Competition wheels; the current tires are 19/57-15 Michelin Circuit GT/Sedan racing slicks, compound - S8B - medium. Originally, the tires used during the Belgian Procar series and the 24 hours of Spa were Dunlop SP Sport racing slicks, sizes 185/580R15 and 200/580R15.



Foss-Tech’s carbon fiber ability was top notch; they used the very best aerospace- and F1-derived processes to ensure maximum strength and lightness as well as entirely vacuum-bagged pre-impregnated carbon that was cured in autoclaves. The strength-to-weight ratio they achieved is phenomenal. The chassis was equipped with carbon fiber door cards, rear quarter panel covers, a driver side Nomex honeycomb carbon fiber side impact X-brace cover, a carbon fiber center console switch panel, a radio delete switch panel, center console side covers, steering rack cover, air vent covers, and, most notably, the brake ducts, bumper ducts, transmission duct, fuel cell containment box, radiator and oil cooler ducting, battery cover, and rocker sill covers. 



The engine cooling is managed by a surprisingly small (half-size) radiator that is aided by sizeable carbon fiber ducting in the front bumper that routes air to the radiator, the air-to-air oil cooler, transmission, brakes, and air box intake plenum. The fuel system features an elaborate FIA-FT3 bladder-type fuel cell that was designed by Premier Fuel Systems and enclosed in a custom-molded carbon fiber casing. Depending on the race, the fuel system can be adjusted to a single 55L cell (under the car) and/or a 45L cell (inside the car). For endurance events, the car can run both cells, for a combined total of 100L (the FIA limit) and use a larger expandable carbon fiber containment case and dual fuel pumps. 



In terms of electronics, an MBE Systems ECU and a custom-made engine harness controls the motor. The system uses a modified OBDI distributor as a camshaft sensor and ignition spark rotor as well as a special crank position sensor built from a modified Type R crank pulley. The ECU and an external Bosch module handle the ignition. Data-logging is carried out by the MBE ECU, and driver feedback is provided through a Stack 8100 dash system with a built-in rear wheel speed sensor, lap beacon, and various engine sensors (oil temp, oil pressure, fuel pressure, water temp). Lastly, an advanced Armtech battery isolation system, Motorola two-way radio system, and electronic fire suppression were also installed.



The engine and transmission did not come with the chassis; Honda Racing Europe supplied special B18C6 motors and a custom-developed Hewland, Brena & WTI dog-gear transmission. The motor is mostly stock but was partially developed in a collaboration between Honda, Mugen, Neil Brown Racing, and ELR specifically for Honda Motors Europe. FIA rules strictly regulated the engine and engine equipment variances, so everything was built to maximum tolerances and efficiency. Displacement for the 1998 season was 1.8L, and the power output was in the 210–220 whp range with a 10,000 rpm redline. The motor is distinguishable by a “Procar” engraving on the block and has custom-machined aluminum block-offs on various emissions control systems. Interestingly, the C6 block currently in the car is one of the lowest numbers I’ve seen for any Honda motor (B18C6 - Procar 1 - 0100017). In addition, and unlike in most race cars, power steering was retained but modified for racing purposes to help minimize driver fatigue during endurance races and enhance the dynamics and rapid turn-in of the chassis. 



The exhaust is a custom setup designed by Mugen, Neil Brown Racing, PSI Motorsports, ELR, and Foss-Tech. It features a 4-2-1 design, a large 2.5” collector, and a thin-walled 3” exhaust with a large stainless muffler and resonated exhaust tip. Depending on the race regulations (for example, the 24-hour Spa Francorchamps), a special high-flow catalyst would be utilized that was easily installed near the factory location. Its use and location was identified by special markings on the exterior side panels for flag marshals and race personnel. Lastly, as part of the air induction system, the air intake system was designed by ELR; it features a large carbon fiber air box equipped with a panel-style air filter and an oval velocity stack located in the front bumper opening. At Spa Francorchamps, positive air pressure was seen at over 130 mph on the Kemmel straight.



The Hewland/ Brena / WTI transmission features custom gears and final drive ratios (these varied by the racetrack but were within the FIA 2% variant tolerance), custom forks, reinforced shift selector, modified shift linkage, and a custom Hewland/Brenda/WTI Powerflow 1.5-way LSD (clutch style). The clutch is an AP Racing metallic racing design with an AP Racing short-throw master cylinder. The driver seat and six-point harness was originally sourced from OMP (King model), but the car currently has Sparco and Schroth parts installed. The steering wheel is from Alpha, and various safety bits come from SPA Techniques and Stand 21.

A telltale Foss-Tech feature is a dark metallic gray interior, white exterior, and hand-engraved plaque located on the driver side A-pillar that displays the Foss-Tech serial number. For this car, it’s FTI-98-03. The original white, red, and metallic gray livery was designed by Belgian motorsport artist Jean-Luc Vanuf for Honda Motors Europe and featured prominently in advertising material. The livery was subsequently repainted to white, dark blue, red, and green (the colors of the Portuguese flag) when it raced in Portugal in 1999 and 2000. 



Amazingly, while the car came in at a scant 2100 lbs, it still has many accessories, such as wipers, modified windshield wiper cleaners, full OE glass, full OE metal body panels, heater/blower, headlights (low/high), turn signals with side markers, parking lights, brake lights, rear fog light, full exhaust, oversized 40-lb battery, ballast box, and power mirrors, windows, and steering. 



Due to FIA rules in 1998, the aerodynamics had to remain mostly stock; however, Honda Motor Europe was able to make some crucial changes to the 1998 chassis to better comply with the rule limitations. For example, the FIA rules say brake cooling ducts can be added in factory lighting locations (i.e., fog lights), but essential lighting equipment (headlights, turn signals, parking lights) cannot be removed. The EDM/UKDM fog light locations were specifically designed to be used as a brake cooling ducts for racing purposes under FIA rules. Some people claim the Type R is mostly hype and marketing material, but a great deal of the special equipment goes unnoticed. These modifications tie directly back into FIA Group N and Super Production rules, especially for the 1998+ US/EDM/UKDM models. 



Individuals that were directly involved with this race program reported that the Foss-Tech/ELR/Honda cars cost well north of $125K and ran over $250K with the addition of the spare Hewland/Brena/WTI transmissions, Honda Racing engines, magnesium racing wheels/racing slicks, and various suspension and fuel setups for each track. To say these cars were built with no expense spared would be an understatement. Honda knew that competitive racing in Europe was a must-win situation, both financially and to prove themselves in the touring car segment.

Foss-Tech was also the official race team for Honda under the Honda Sport Belgium—Honda Access Accessories livery. Four-time Belgian Procar/European Endurance champion Thierry Tassin was the primary driver, and Philippe Favre served as a codriver for endurance events. Tassin is most noted for his time racing the BMW 6 series under the Bastos livery in the early 80s, the Ford Sierra RS Cosworth in the late 80s, the BMW E30 M3 Sport Evo and E36 320i under the FINA/Bastos livery in the early 90s, and the Stella Artois/Mobil 1 (Team VZM) Honda Accord in 1997. Philippe Favre was primarily known for his time in the F3000 series and driving under the Kenwood and Maxell livery for Kremer Racing NSX GT1 & GT2 cars in the 1994 and 1995 24-hour Le Mans.



In 1998, the car competed in 14 races and achieved 4 wins, 8 podiums, 1 pole position, and 6 fastest laps (including several track records). It finished with 188 points, was runner-up in the drivers’ championship, and helped Honda clinch the Manufacturers’ World Championship. It was also awarded the prestigious Coupe du Roi trophy in the 1998 24-hour Spa Francorchamps after leading the race for almost 17 hours straight. The trophy, given to the most consistent car, is one of the oldest awards in motorsports.



In 1999, ELR sold the car to José Pedro Fontes, the reigning Portuguese rally champion. He raced it in the Portuguese Touring Car Series (Campeonato Nacional de Velocidade) and won the championship that same year. In 2000, he competed in one more race (which he won) before retiring the car to focus solely on rally racing. While the livery was changed, the car’s equipment and setup remained original. In fact, Mr. Fontes would frequently fly ELR to Portugal to inspect and prepare the car for races.



In December 2014, after 14 years in storage, the car was sold to Alexandre Nogueira (Portugal) who competed in the 2015 Portuguese Historic/Legend series (Campeonato Nacional Legends Cup) and won the championship that year. In 2016, he competed in two more Legends Cup events and won both before the car was retired yet again.



In 2017, I purchased the car from Alexandre with the intention of importing it to the USA so I could restore it to its original Belgian Procar livery, thoroughly document its history, and enjoy it at local open track day events and historic racing series. I had been in communication with Alexandre since shortly after he acquired the car, as I was restoring the yellow race car at the same time. My research into the yellow car made me a somewhat of an expert on the Integra Type R's involvement in the 24-hour Spa Francorchamps, the Belgian Procar series, and various European race teams and race series. Foss-Tech, ELR, the 1998–2000 24-hour Spa Francorchamps, and the 1998–2000 Belgian Procar series became my specialty. While I wasn't in the market for another race car, I knew it had to go to a good home, and I realized I couldn't live with myself if it slipped through my hands. After a few weeks of negotiation, we agreed on the particulars, and the car was loaded into a container bound for the USA.



I’ve spent a significant amount of time gathering historical racing memorabilia on this car and communicating with those that were involved in its racing history, including William at Honda Motor Europe, Marc at ELR, and various photographers and journalists.



Importation of the car was complex and challenging; I received a Racing Exclusion letter from the EPA, approval for Box 8 exemption status on the SH-7 form from the NHSTA/DOT, and special Customs clearance via a clearing house broker. I also had to get an email and letter from Honda as well as several emails and letters from ELR authenticating its history, ownership, and pedigree.


Interesting FIA Super Production & Group N rules tidbits and impact on the development of the Integra Type R:

- Per FIA rules, “The original apertures in the bodywork (e.g. for fog lamps) may be used for the passage of the cooling air. The connection of the air lines to the original apertures in the bodywork is free as long as these apertures remain unchanged”... “The original lighting system must be retained, with the exception of the fog lamps, and must be operational at all times during a meeting. The headlights must have a road homologation for all countries (ECE, DOT, etc.). The fog lamps may be removed for the passage of the cooling air.” This is why the EDM/UKDM cars have optional fog lights in the bumper rather then in the radiator opening like USDM cars. If you look closely, all Honda/Acura 98+ bumpers have casting marks outlining where to cut the bumper for the fog lights (even USDM cars). The location is critical as it perfectly lines-up with the brakes making it ideal placement for brake ducting rather then taking up space in the radiator bumper opening which would interfere with cooling, air-to-air oil coolers and would require cutting of the radiator support structure. This is also why the factory bumper lights (or headlights/high beams) were never used for cooling as the FIA required they be retained and functional.

- FIA Super Production rules stated that “at least 2500 fully identical units must have been produced in 12 consecutive months and homologated by the FIA in Production Cars (Group N).” I need to speak with my contact at Honda who worked directly with the FIA on Homologating the Type R, however, I’m not sure how Honda got around the 2500 fully identical unit requirement unless they referenced JDM production numbers even though those cars had a different setup then the UKDM/EDM models.

- The reason for all the (interior) carbon fiber panels were because of rules. Per the FIA, “Neither the front and rear door panels nor the rear side panels may be removed. These may be the original ones or be made from metal sheeting at least 0.5 mm thick, from carbon fibre at least 1 mm thick or from another solid and non-combustible material at least 2 mm thick. The panels must totally cover the door, its handles, locks and window winding mechanisms.”

- The EDM/UKDM used unique 15” wheels to meet FIA requirements. Super Production was limited to 15x7 and Group N were limited to the manufacture homologated specifications. Per the FIA, “The wheels are free, respecting the homologated diameter, and the homologated width which is considered as a maximum.” From a gearing, performance and racing slick perspective, the 16” JDM wheel wouldn’t be possible. I’m not 100% sure why they didn’t run the Civic EK9 Type R / USDM Type R wheels, but I’m guessing it was for aftermarket brake caliper clearance reasons. Group N had to use factory brakes but in Super Production, AP Racing and Alcon were the standard units being used. JDM calipers (Spoon) were very uncommon due to poor performance from being limited to factory rotor diameters and thickness.

- Speaking of wheels, the EDM/UKDM cars also used JDM gearing. Coupled with 15” wheels this provided the best performance possible under the FIA homologation.

Unfortunately killed in a skiing accident in 2013

Philippe Favre (CH-Swiss) spent his racing career driving in Formula Ford, Formula 3, Formula 3000 before being signed as a driver at Kremer Racing in the sports car ranks.

His career brought him to Le Mans on multiple occasions in a GT1 and GT2 Honda NSX, and spent much of the remainder of his time in sports cars, in a Lucchini SR2 in FIA Sportscar racing.

From 2003-2005 he competed in the Le Mans Endurance Racing series with Christophe Ricard.

Favre built a track day company in 2002, assisting numerous drivers learn the sport, including current endurance driver Henri Moser.

He started racing in French Formula Ford 1600 in 1984 after a short karting career and shifted over to Britain to continue in FF1600 the following season.

A second year in Britain in 1986 yielded the runner-up spot in both the RAC FF1600 championship and the prestigious end-of-season Formula Ford Festival at Brands Hatch with the Manadient Van Diemen team.

Two years in the British F3 Championship in 1987-88, which included a victory with the works Reynard R+D team at Donington Park in his debut season, were the springboard to F3000.

Favre claimed pole position and second place on his maiden event in the final stepping stone to Formula 1 at Silverstone in 1989, but he was never able to recapture that form over the remainder of a truncated season with the GA Motorsport Lola squad.

He continued in F3000 with part-seasons in Japan with Team Noji and Leyton House in 1990 and then briefly raced in Indy Lights in the US, before being picked up by the Kremer Racing Honda sportscar team.

Favre made two starts in the Le Mans 24 Hours in Honda NSX GT1/GT2 cars in 1994-95. In 1995 he took 3rd place in the 24hrs of Spa Francorchamps driving a Honda Accord for Team VZM. In 1996 he was the lead driver for the factory-run Venturi 600LM in the BPR Global Endurance GT Series.

In 1998 he joined Thierry Tassin in driving the Honda factory team (ELR) Integra Type R in the 24hrs of Spa. In 1999, he returned to the 24hrs of Spa to drive a Honda Accord for team ELR. In last half of 1998, throughout 1999 and in the first half of 2000 he drove a Porsche 911 GT2 for various race teams in the FFSA/FIA GT Championship, 24hrs of Daytona and the 6 Hours of Vallelunga.

In 2000, he joined the factory Lister team to race in the FFSA/FIA GT Championship. He claimed podiums at the Hungaroring and Brno and continued to race for Lister until mid-2001. In mid-2001 he returned to driving Porsche GT2's, GT3-RS's and GT3-R's in the FFSA/FIA GT Championship.

In 2003-2005 he raced a Lucchini SR2000 in the FFSA/FIA Sportscar Championship and Le Mans Endurance Series.

51. Tested new (original spec - Walther Prazision) air jack coupler and verified normal leak-free operation
52. Discovered passenger rear brake was stuck, upon inspection I found the inner brake pad alignment notch was misaligned causing the pad to make uneven contact with the rotor. This would explain the minor brake stability issue I noticed while on the track. New rear rotors and pads (original ELR spec) are on order.
8/26/2017 - 8/27/2017
53. Worked on other race car
9/2/2017 - 9/3/2017
54. Finished rebuilding the motor and transmission on the daily driver
9/9/2017 - 9/10/2017
55. Installed and tuned motor for the daily driver
9/16/2017 - 9/17/2017
56. Repaired carbon ducting for oil cooler (side plate was previously damaged – replaced with a new piece)
57. Overnighted MBE Systems ECU to Europe for chipset and software update/upgrade
58. Replaced ELR air filter with a new element
59. Attempted to remount seat without success (head protection is interfering with roll cage - will need to try an alternate solution such as using different brackets or trying a different seat design)
9/23/2017 - 9/24/2017
60. Removed original and faulty (AP Racing) clutch master cylinder to get the part number and order a replacement unit.
61. Installed a new smaller and lighter battery (10lb weight reduction)
62. Refinished ELR clutch master cylinder adapter plate
9/30/2017 - 10/1/2017
63. Installed (overhauled) MBE Systems ECU and verified everything works as expected. Will require a retune but it's working very well thus far.
64. Installed a new clutch master cylinder & firewall adapter bracket
65. Bleed clutch master cylinder
66. Removed ELR clutch pedal cover to minimize change of clutch pedal bind while I adjust the clutch throw
67. Test drove car and verified clutch master cylinder is working
68. Discovered clutch will not disengage even after adjusting the clutch master cylinder. The clutch disk like broke a spring and will need to be replaced
69. Ordered a new clutch pressure plate, clutch disk, flywheel, pilot bearing, throw-out bearing, clutch slave, clutch fork and clutch fork spring
9/30/2017 - 10/1/2017
70. Removed transmission clutch and flywheel
71. Discovered the release bearing and clutch are AP Racing units and the flywheel is a custom modified OE unit. The clutch is a single plate, one piece aluminum stepped design pressure plate with a 4-puck/paddle rigid disc. The flywheel was modified to be a stepped design and have mounting studs machined/welded onto it with anti-rattle springs. The entire setup it quite impressive, especially by 1998 standards. Also the entire assembly weight is roughly 21lbs, about the same as a standard "steel sprung" clutch with a lightweight flywheel.
72. Discovered the passenger side axle was stuck inside the differential. Will need to repair transmission housing and replace both drive shafts
73. Discovered the Hewland gear set is actually a Brena/WTI gear set in a modified Hewland case
74. Discovered the transmission casing has extensive modifications for clearance and improved oil flow
75. Discovered the transmission case has HEW1 and HRC-012 (serial number) engraved in the case
76. Discovered that all the suspension bolts and nuts were changed to a higher grade and same size (likely for rapid pit work)
77. Discovered the Penske suspension has ELR engraving on struts and springs
78. Shipped transmission case to machine shop for repair
79. Ordered new "road race" drive shafts
10/14/2017 - 10/15/2017
80. Removed and shipped Penske suspension for full rebuild/overhaul
10/21/2017 - 10/22/2017

10/28/2017 - 10/29/2017
Waiting on parts to arrive...
11/4/2017 - 11/5/2017
Waiting on parts to arrive...
11/11/2017 - 11/12/2017
Was at the Creventic/Hankook 24H COTA event with Marc from ELR (who built and oversaw this car) and Mark (who built, raced and oversaw my yellow race car)
11/18/2017 - 11/19/2017
Worked on daily driver
11/25/2017 - 11/26/2017

12/16/2017 - 12/17/2017
Holiday stuff
12/23/2017 - 12/24/2017
Holiday stuff
12/30/2017 - 12/31/2017
Installed new clutch release bearing, clutch slave, clutch fork and clutch fork spring
Installed new pilot bearing, flywheel and clutch
Installed new custom sequential transmission
1/6/2018 - 1/7/2018
Installed blueprinted and rebuilt Penske suspension (thank you Anze)
Installed new Road Race "vented" axles
Installed shift mechanism & gear display
1/13/2018 - 1/14/2018
Installed blueprinted and rebuilt front brake calipers (thank you Essex)
Installed new front (Pagid RS-29) brake pads (will burnish after the rears are installed)
Full flush and bleed entire brake system
Replaced failing front lower ball joint (driver side)
1/20/2018 - 1/21/2018
Installed transmission wiring harness, ECU and sensors
Added break-in fluid and finally got the transmission running
Calibrated the mechanical shift-linkage and set the shifter stops
Broke-in the clutch LSD (driving in a figure 8 for about an hour)
Verified ignition cut functionality and initial transmission (electronic) settings
Did a baseline dyno pull and verified the air/fuel ratio needed to be adjusted at partial throttle due to the new chipset in the MBE ECU. Power is 212whp & 142 trq.
Wasn't able to fine tune the transmission ECU or verify WOT ignition cut because I ran out of gas on the dyno. Oops.
Also discovered the power steering system is starting to fail as it overflowed on the dyno due to fluid starting to foam. I also noticed this happened on the track earlier last year. Likely it's a result of a failing power steering pump (you can also hear it whine while idling). New parts ordered, the entire system will be overhauled or replaced as needed.
1/27/2018 - 1/28/2018
No progress - was tied up all weekend with getting a new pit dug and cement poured for a new chassis lift (Bendpak SP-7XF)
2/3/2018 - 2/4/2018
No progress - cleaning shop & wash hosed off both race cars
2/10/2018 - 2/11/2018
No progress - family stuff
2/17/2018 - 2/19/2018
Installed new OMP carbon seat (WRC-R - carbon core - 10lb weight reduction over the old seat)
Installed FIA fixed mounted and light weight seat bracket
Adjusted harness for new seat location
Reinstalled center console and switch panel
Cleaned up ECU wiring
2/24/2018 - 2/25/2018
Not much progress - spent Sat working on the Lawrencebuilt drag car
Installed the carbon fiber lid for the ballast tray
Secured the shift boot to the sequential shift lever
3/3/2018 - 3/4/2018
No major progress - had to work on tax stuff
Installed a carbon replacement cowl cover and relocated the battery cut-off button to the original location (next to the fire suppression system button). The original cowl cover was heavily worn and the new carbon cover limits the amount of engine bay air that can get pushed into the cabin.
3/10/2018 - 3/11/2018
Ryan Conley came over for a visit and guess what? #ryanconley
I took the car for a quick drive around the parking lot and discovered the fuel drain valve was leaking. I put the car on the (new) lift and found the value o-rings have failed which allowed pressurized fuel to leak from the open/close knob. A new FIA approved Staubli SPT valve will be installed next weekend. Thanks Ryan! :clownshoes:
I also replaced the pad holder bolt on both from calipers. After the caliper rebuild I needed to replace both bolts with a identical unit.
3/17/18 - 3/18/18
Removed leaky fuel drain valve and replacing with a -6AN plug until the Staubli valve arrives
Installed new rear rotors and modified Pagid RS4-2 rear brake pads (modified to HRE "Honda Racing Europe" specifications) - thank you Jack Myers of Myers Competition Products! A+ work as always :thumbup: :thumbup:
Disassembled spare power steering pump for rebuild. I'll first start with rebuilding the spare pump. If that works then I may or may not replace the other parts at this time.
3/24/18 - 3/25/18
Rebuilt the power steering pump (will not use at this time)
Removed the power steering system hoses/lines
3/30/18 - 4/1/18
Installed Stäubli (dry break) fuel drain valve
Installed new power steering pump
Installed new power steering pressure line
Installed new power steering low pressure lines
Installed new power steering reservoir & bracket
4/7/18 - 4/8/18
Installed a new power steering cooler unit inside the oil cooler ducting and bleed the entire system
Adjusted the partial throttle compensation and 3D fuel maps
Tested full throttle sequential shifting at 9k rpms. Wow!
4/14/18 - 4/15/18
Installed new front & rear upper camber arms & spherical mounts
Installed new rear toe links
Installed new radiator and hoses
Installed load cell on shifter rod
4/21/18 - 4/22/18
Corner weighted
Aligned chassis
4/21/18 - 4/29/18
Install AiM EVO5 w/GS display for increased data telemetry
Resume dyno tuning & possibly install an adjustable fuel pressure regulator
5/27/18
NCRC Track Day @ Laguna Seca!

To-Do items over the next 2-5 months
Replace fuel pumps, filters and inspect hoses
Order OE spec Dunlop racing slicks and mount on newly refinished wheels
Send original fuel bladder to Premier Fuel Systems for replacement
Strip/repaint exterior and return exterior to the original livery before Expo 18 (West Coast)
Overhaul and replace original brake lines/bias controller
Install new front LCA arms


Dyno Tuning Progress

Yellow/Orange = Baseline, no changes outside of adding fluids and gas
Green = Retuned AFR and timing
Red = Retuned with a spare/alternate cylinder head and cams
Blue = Retuned after replacing the original 4-1 Mugen exhaust manifold with a 4-2-1 Toda style exhaust manifold

Takeaways: While the Toda style header loses a decent amount of power/torque between 5800-6800rpms, the engine for the most part stays above 6800rpms on track. We'll either do some additional tuning and/or will try a few different exhaust manifold setups to find the sweet spot. Right now it's good enough considering it's making 10-20whp more then the last time it was on track (the green curve).

Yeah the UKDM/EDM fog light thing is pretty interesting. Per the FIA, “The original apertures in the bodywork (e.g. for fog lamps) may be used for the passage of the cooling air. The connection of the air lines to the original apertures in the bodywork is free as long as these apertures remain unchanged”... “The original lighting system must be retained, with the exception of the fog lamps, and must be operational at all times during a meeting. The headlights must have a road homologation for all countries (ECE, DOT, etc.). The fog lamps may be removed for the passage of the cooling air.”


Other interesting tidbits are:

- FIA Super Production rules stated that “at least 2500 fully identical units must have been produced in 12 consecutive months and homologated by the FIA in Production Cars (Group N).” I need to speak with my contact at Honda who worked directly with the FIA on Homologating the Type R, however, I’m not sure how Honda got around the 2500 fully identical unit requirement unless they referenced JDM production numbers even though those cars had a different setup then the UKDM/EDM models.

- The reason for all the (interior) carbon fiber panels were because of the rules. Per the FIA, “Neither the front and rear door panels nor the rear side panels may be removed. These may be the original ones or be made from metal sheeting at least 0.5 mm thick, from carbon fibre at least 1 mm thick or from another solid and non-combustible material at least 2 mm thick. The panels must totally cover the door, its handles, locks and window winding mechanisms.”

- The EDM/UKDM used unique 15” wheels to meet FIA requirements. Super Production was limited to 15x7 and Group N were limited to the manufacture homologated specifications. Per the FIA, “The wheels are free, respecting the homologated diameter, and the homologated width which is considered as a maximum.” From a gearing, performance and racing slick perspective, the 16” JDM wheel wouldn’t be possible. I’m not 100% sure why they didn’t run the Civic EK9 Type R / USDM Type R wheels, but I’m guessing it was for aftermarket brake caliper clearance reasons. Group N had to use factory brakes but in Super Production, AP Racing and Alcon were the standard units being used. JDM calipers (Spoon) were very uncommon due to poor performance from being limited to factory rotor diameters and thickness.

- Speaking of wheels, the EDM/UKDM cars also used JDM gearing. Coupled with 15” wheels this provided the best performance possible under the factory FIA homologation.

I’ll post up more facts as I get time.

This thread is great. :thumbup:

I'll admit to not knowing the fog light and FIA rules usage, but it makes sense. In a way, a lot of the Integra Type-R's history seems to have little bits like that focused on racing.

I really hope to see this car someday...
