Aluminum headed combo 2006:
Unfortunately, I haven't run the car too much with the GN1-R's because of AFR problems I was chasing down. I changed 3 things since those times above....the heads, the intake and the intercooler...all three are still on the car. I was still using the same 70 P trim turbo and ATR roller cam. The best run was a 6.69 at 104 with 25psi of boost with unstable AFR's. The car also weighed more... about 3580lb. So, I guess I can say that running 5psi less boost and the car weighing 130lbs more these changes helped.
Since the above aluminum headed times, I've a added a FAST XFI... which fixed my AFR problems and added a stroker crank and a 220-224 cam.
any new numbers for this combo ? how much the new heads, stroker crank and a 220-224 cam was worth ??
