Help low mph with h/c
I have a 224/228 586 596 113.9 in my car right now. I only put down 379.8 RWHP before true duals and an asp pulley. My car on friday ran on the motor 12.37@110 n/a and a 11.20@121 squirting 100. Something is def not right. I have PP S2 heads ,LS6intake ,Pacesetter headers and this is all I have run. I should at least be trapping 115-116 n/a. Im going to do a compression test on the car and see what that brings.

Maybe a timing issue? Possibly false knock and the PCM is cutting timing, thus lack of power? Try A-tapping while running some full-bore passes and see what is going on.

what gears do you have now 3.73 er...?? Last time i hit the track pushing 373 to the wheels with a bogg off the line w/ my 2.73's i trapped 112 in 70 degree weather...im hoping we can fix my issues and get that mph up to 114ish...bottom line i think your #'s are off but what conditions was this in, what gears? Any noticable issues with the car?

Do your Pacesetters hit the k-member? If so you may be getting some false knock which can be retarding your timing, causing lack of HP. AutoTap that **** and see what the KR is and timing, may answer your question
