Guys,
Here is my dilemma, I am trying to get into the 11’s on my Nitto drag radials (275/50-15). It seems like I am out of gear on the big end. I know the Nittos are just under 26” tall and I believe that could be my problem. My car runs 12.2s at 112 mph with a 1.8-1.9 60ft time. (Best run 12.26 at 112.77mph with a 1.97 60 ft) I have yet to get a strong run with a good 60ft together. I am leaving with 3.5-5psi of boost. See my mods below. Any suggestions for:
Air bag psi (Left and Right side)
Nitto psi (I have run as low as 15psi – seemed too low)
Should I shift into OD (I run in Drive)
Should I lock up the TC (I can add a switch)
How long should I do my burn out? (Wet or Dry?)
Also, am I out of injector or fuel pump??
My car leans out on the big end O2 = 715 – 730 at 113 mph (via scanmaster and Turbo-link)
With a 112 mph trap speed, do I have enough fuel?
TA49
Blue Tops
307 pump
Adj Reg set at 46lbs (vac line off)
Translator Plus and LT1 MAF (WOT Fuel +2% added – still seems lean)
Alky Injection
Sorry so many questions - Please help.
