Its still very cool weather and it is hard to not spin which looses time.

I have the Phantom grip and factory tires but must start at about 1200 - 1400 rpm and roll out to keep from slipping (blowing off the tires, cause once they slip they are flat gone till you get all the way out of it). The traction control is off, as that has a habit of killing the throttle and introducing a BIG bog like effect. When I get the LET 181 pulley and install the heat exchanger I will try it again to see if there is a measurable difference.

Trouble here is that we only have 1/8th mile tracks and they are not open for test and tune events yet. Figgured that I could get some other peoples numbers for comparison in the mean time, thanks
