2005 Ford Saleen Mustang - Magnificent Obsession

Better, Stronger, Faster
Delivering the Saleen to Livernois in April 2006, the stock engine internals were exchanged with a forged stroker crank, rods, pistons. The engine displacement was not 5.0 liters. The cylinder heads were CNC ported and polished and the OE exhaust manifolds fell to a set of JBA's HPC ceramic coated shorty headers. It gets more interesting though. At the same time, the stock 5-speed transmission was replaced with a D&D Performance "Viper spec" Tremec T-56, 6-speed transmission, fitted with a RAM clutch and an aluminum driveshaft. The stock motor's hydra-mounts were replaced with Steeda's uncoupled heavy duty mounts and the stock air intake was replaced with a Steeda kit. The original fuel injectors were upgraded to 39 lb/hr units. The Saleen supercharger was reinstalled with the stock 4-inch pulley and the engine was tuned.
After racking up about 1,200 miles of break-in driving, Peter took the car back to Livernois for the rest of the work. "In early July 2006 the car was returned to Livernois and additional performance parts were installed so that the car could best reach my desired objectives. The existing fuel pump was replaced with a GT500 dual fuel pump, module and wiring harness. The 39 lb. fuel injectors were replaced with 60 lb versions. The Steeda CAI was replaced with a C&L racer tube and MAF meter. The MAF sensor was replaced with a Ford GT MAF sensor." Beyond these changes, the rear gears were also replaced with 4.10 versions and the stock Saleen boost and air intake temperature gauges were replaced with AutoMeter Cobalt units with wider ranges.
Some additional work with pulleys and the serpentine drive belt lead to a reliable increase in boost that just needed a little detuning to smooth out its onset for road racing. "The more manageable tune produced 470.6 RWHP and relatively modest 441 RWTQ. After some track time, I will be back to return to a more aggressive tune." Still, before serious road work could be undertaken, Peter knew that he had some suspension work to get done. Larger rear tires, a set of control arms and a Torsen T-2R Racemaster differential were mandatory in his view. So was widening the original Saleen rear wheels to take the new rubber.
He started by heading to the Mid-Ohio road course in July 2007 for some driver training and high speed lapping on their 2.4 mile road course. It was a learning experience for him, as well. "First, the car I built has far more capacity to run fast laps than this inexperienced driver currently has the skill to attempt. This was driven home to me when I had the pleasure riding passenger when my car was driven in the pouring rain by Mid-Ohio instructor Tommy Byrne. Tommy was quite complimentary on the brakes, handling and 'unobtrusiveness' of the supercharger. He said he was pleasantly surprised with how well it handled. However, he did advise me not to continue high speed laps that day in the rain."
A few new issues had become apparent to Peter. Resolving them involved, on one hand, a Recaro sport seat and Schroth 6 point racing harness. Further increases in lateral-G capacity had also become important to him, so a Saleen Watt's linkage was ordered up and installed. Peter is heading back to the Mid-Ohio track shortly and looking forward to evaluating the results of the latest changes. He's quite pleased with the Saleen right now. "I believe this car is well on the way to meeting all my goals as a street car road racer and I am looking forward to continually tweaking and improving the performance and my driving skills as long as I own it."
Does that sound like an obsession? If so, it is certainly a magnificent one.
