When a t WOT from a star the car is super fast even at high RPM in 1st gear let it shift at 5500 and then second gear is fast till it gets around 4800 RPm and then i shift at 5800 RPM . Just seems like a lack of tope end power how do i get more without sacraficing that much low end power. I know a larger pipe size 2.5" in the exhasut will help and that is coming soon (next weekend) but is there anything else i can do.thanx

I see you have PEMS ,if you have done the front and back right they will help,the L-36 responds well to exhaust mods so I would suggest a 3" DP to hi-flo cat to 2 1/2 " pipes to the muffs,next as noted above some 1.8 or 1.9 rockers and a PCM will help also a HV TB such as ZZP stage 1 and even HVII will work with the rockers and DP ,with the proper setup the N/A 3.8 will pull good up top.Chico.

How does your car compare to a stock GTP? I'll bet you blow peoples minds with that beast.

GrnHornet how do you figure your car is a lot lighter?and as far as you racing a GTP a stock GTP runs in the high 14's stock and your car would would be about a second behind,and bryanp if that comprison question is for me go to my web site and check out my time slip that time is N/A ,does that answer your question .Chico.

Be casue my car weighs 3330 a GTP weighs 3500 and at GT weighs somewhere around 3400. I have the SE L-36, thats why i said mine is lighter. and ive alson done slight weigh reduction to drop around 35 pounds. When i run my 1/4 miles there nothing in the car. gutted. and i will tryn and find my time slip and post it up to show you my times!
