Spun bad on the third pass after following several street cars that drove through the water box

I missed 2nd gear on the last pass, it may have bested my 12.339... There's still some tweaking to do with tire pressure and shock/strut settings. I may have a high 1.5x 60' left in the car, and maybe 12.2x ET by years end.

winter plans: bump rev limiter to 6800, urethane diff bushing, and double adj shocks - those should help me knock a few more hundredths off...

I can't race under a 1/4 tank I get an interruption when I launch like if the engine shut off for a half sec.
idk how you get away with 1/8 tank on the strip!

Congrats lindertw!

What are the diameter of your ET streets, and what rpm do you go through the traps at?

m/t et street p/n 3752 (26.1" diam per their page) with 4.10 gears. I never look at the tach when going through the traps, but using a calculator the three good passes posted above I went through the traps at just over 5700 rpm.

rpm = (mph x final gear ratio x 336) / tire diameter
