1995 Porsche Cup 3.8 RSR – Current Specifications

This is a factory race car originally purchased in April 1996.  

Chassis

This RSR was upgraded to a GT2 factory race chassis by Kelly Moss Racing– based on the wider 993 Turbo – which allowed adding wider EVO bodywork, wheels, and tires.  The original VIN was transferred to this GT2 chassis in 2000 – 2001.  All engine, transmission, and suspension linkage points are solid mount as came from the factory.  Front uprights are upgraded to the EVO units to eliminate bump-steer issues.  Rear suspension has an anti-squat removal spacer as is common with these cars.  Rear deck is from the 964 3.8 car (reduced drag) and the wing is Crawford carbon-fiber “banana” design. Not pictured, but included in the sale. Doors are hollow shell carbon-fiber with no windows. Factory air jacks were all refreshed. 

Tires/Wheels

BBS Centerlock Fronts  0228039 10”  wide running Yokohama 250-650/18 slicks (Rim halves 2” & 8”)

BBS Centerlock Rears 0228051 12.5” wide running Yokohama 320-650/18 slicks (rim halves 4.5” and 8”)

Brake

Brakes are as on the 993 Turbo with the original RSR racing ABS.  AP600 fluid is used, bled before each event.  Front KMR brake cooling duct package.  These ABS brakes with 10” front slicks can out-stop most any Cup car.

Shocks

Penske 3-way adjustable remote reservoir shocks, with KMR valving/shim packs.  These cost about $12,000 new.

Sway Bars

Kelly Moss spec cockpit adjustable sway bars, Front and Rear. Expensive and worthwhile!

Safety

Halon fire system – factory bottle was replaced by USA model as original (included in sale) could not be shipped for refill.  FIA Sabelt HANS 6-point 3” /2” belts.  Window net per PCA requirements.  Brey-Kruse seat-back brace per PCA regulations. 

Weight

Car weighs 2385 lbs per last corner balance without driver or fuel.  Has carbon fiber or fiberglass nose, front fenders, flares, rear bumper, wings, under-trays, and Lexan windows all around.  Carbon fiber front shock brace by Brey-Kruse. 

Fuel

Fuel Safe 100 liter fuel cell with fast-fill connectors (not used by current owner), updated with new cell liner and wiffle balls. Non-linear fuel gauge with low fuel warning light in console.  Bosch 044 fuel pump with AN hoses and dual pick-ups in baffled and valved sump inside tank.  Newer Bosch 5-bar fuel pressure regulator.

Engine

This 3.8 liter engine was “Sprinted” by PMNA/Andial in 1998, which included special cams, exotic ported heads, and an “EFI”-brand engine management system.  It has Mahle P & C’s.  A Sprint head cracked in 2003, and all were replaced with new standard RSR heads (no crack-causing porting). Compression lowered with base shims to 11.7:1 and ignition and cam timing has also been pulled back a bit to reduce stress and add life.  The EFI system was re-calibrated on a dyno for the current de-tuned setup, producing 296 rear-wheel HP.  This adds life to the engine but sacrifices HP. If you want to run faster, the engine can be hopped-up to around 400HP with a sacrifice of longevity.  EFI software and cable is included for your XP laptop.  Engine was freshened in Oct. 2013 with ARP through bolts and new bearings etc. and has 0 hours.  Rocker arms are mechanically adjustable as per most RSR’s, which moved away from the valve lash-cap design.  Intakes have PMNA risers to improve low-end torque, and exhaust is PMNA “large-tube” SS headers – part of “Sprint” package.  Only  tracked at Rennsport since work. Started and move monthly.

Clutch

Tilton 3-plate 5.5” sintered-metal clutch with Aasco light-weight aluminum flywheel and Tilton annular throw-out bearing.  Throw-out and pilot bearings, and clutch-plates new Oct. 2013.  (Also from PMNA “Sprint” mods.)

Transmission

The limited-slip differential is now by “Guard” (the ring gear mounting flange on the Porsche diffs crack). 9:31 R&P gear. Transmission rebuild/refreshed Oct 2013 by Cervelli (Denver).  Gearing has been extensively modified for the tracks I visit as follows (speeds at 7400rpm redline):

1st   12:34   57.8mph

2nd  21:42  81.8mph

3rd  19:30   103.6mph

4th  21:27  127.3mph

5th  23:26   144.8mph

6th  41:42   159.8mph
