What 1/4 should I run at the track?
Been itching to know since I got the car back from its rebuild but I haven't had the time to go.... YET.
 87 Daily Driver Gn: Newly Rebuilt Engine and Tranny to stock quality. TA-49, Dutt Neck, Hot Wire, 60 lb inj, adj FP reg, TT 93 chip, Maf Trans + homemade intake. 18 psi @ 93 oct. Stock suspension, Stock Converter, Stock headers/downpipe/exhaust. Car holds well with 215's at 4lb launch. (I know they are tiny.  )Thing is, I promised a bud of mine who owns a 2007 stock GT-500 he would get the first race. He has never been able to launch the car right and he got a 14.4 on his first try.  Think I have a chance against him if he gets near the rated 1/4 time for his car? I think it could be damn close.

Good short time and I would say a mid to low 12 is in your combo. Some have gotten to the upper 11's with less injector.

If you only run 18#, 93 octane, and 215 tires you will be doing well to get mid 13's. I hope you don't have any money on this race.

No money on this race, we both are struggling with that anyway.  I think if I played my cards right I could hit low 13's or the tip of 12's. But of course that is just positive thinking.

A long time ago when I was running a combo like yours, my best run was 12.91@109. I was running race gas, 20 something boost, Red Armstrong chip and Kelly Springfield (235-60/15) street tires with a 2.193 60'.
