Below is what I'm running, well except I'm running 4 1/2 psi and it spikes to 5 psi. Running 108 (consistant 108 - 111) mph through 1/4. Not timing it just running to the end.

I tried using the G Tech this weekend. It is saying that I'm running 12.639 at 108.9 mph. Is that possible?

street tires, slipping clutch, and a passenger (185 lbs)

 

with a 112 trap i would say like 13.1 area with traction
i was trapping 112 with bad 60's and made a 12.89 pass was best on my old set up
