Tighter Convertor vs. Heads?? Also, what will I run?

[CuzzinOlaf]

Below is my current setup on e85. I recently purchased a 6266 Turbo, valve springs, a power logger and wide band. I was thinking of getting a tighter convertor and/or possibly heads. Where should I be with this setup in the 1/4? What is going to be my next biggest bang for the buck?

Stock long block, stock heads, TA49 turbo, Terry Houston 3" Downpipe, ATR Pitbull Exhaust, Racetronix 510 LPH double pumper, 80lb Injectors, TT 5.7 e85 chip, Hemco modified 62MM upper Plenum, Stock location Intercooler & a half, Relocated Air Filter to under front air dam with 4" duct work ("Tylco Tinman system" ), Jimmy's Stage III transmission Vigilante 2800-3200 convertor with MT Drag Radials 255/60/15s. With this setup the car went 12.02 @ 111mph @23.5psi with a 1.699 RT.

Heads for sure I had good luck with the Vigilante 10% slip on high 10 second passes on a stock longer car

Just to give you an idea my stock longblock TTA went 10.80@124 with a 6262 and vigilante Trapped 125 plus a few times

Maximize what you have before you throw more parts on it .. that combo is good for lower 11's all day

I agree with Turbo89 You should get low 11s with what you got
