1/4 mile 14.30
1/4mile mph 98.02

second run with m/t's and cut off open

the lower the DA the better your car will run.

DA- Density Altitude; which referes often to the quality of air.

Lol thanks guys for the info. The density altitude was 813ft. and relative density was 97.64%

Did you still spin alot off of the line? Or did the tires hook pretty well?

Did you go to the track in Edinburg? I've got quite a few friends that go there and run.

I ran a 2.15 on my stock tires with little to no tread left. This could be track prep, though.

If you can get your 60's down to the 1.9-2.0 range you will hit 13's... trap speed seems a tad low for the mods though.

The tires hooked really good man felt nice when I let go off the brake and floored. And yeah the track I went to is in edinburg.

Yeah actually thinking maybe the tunning wasnt done as great.
