On December 8, 2001 a group of us from S.O.G.I. met at Bullish Motor Racing for a Dyno session. That day, I was able to extract 243.4 horsepower (at the wheels) out of just under 9 psi of boost. Needless to say I was very happy with the result since it equates to about 304 horsepower at the crank. That is a 72 horsepower increase over stock (232 horsepower at about 6 psi of boost) from a 3 psi increase. That was done before I added the Lexus AFM and the rest of the fuel upgrades (580cc injectors, Walbro pump, AFPR and HKS S-AFR). That only made me optimistic and excited about the potential for power at my future mark of 15 psi of boost!...
A year and five days later on Dec. 14th 2002 (timestamp on the chart is incorrect), I returned to the dyno (this time at S.P.I. which is also in New jersey) only to realize my goal of 15psi of boost. This time it yielded and awesome 332.6 horspower at the wheels along with 334.2 ft/lbs of torque. Thats another 89.2 horsepower over the first run of 243.4! That equates to about 415 "Z06 Corvette eating" horsepower at the crank! Enough said! Fast forward to Summer 2004, and I managed to squeeze out another 14 rwhp, totaling 346 rwhp. This was done while battling some boost issues which I hope to address soon. The final plan is to get the car to comfortably push 450 rwhp which will keep the tranny well within its efficiency range. I'm hopeful that this will be realized in 2005.
