hay guys made the first trip to the track with the yukon it wasnt as good as i wanted but not bad for a 4 door house we did 13.9 at 92mph but that is the first trip we made to the track on 6 pd of boost and 13 degrees of timing i think ill bump the timing to 18 degrees total and lean it out some and try again in about a week i think it should run 13.5 or so then ill do the new heads and intake then i will try for 12.9 or so dos any buddy have any times on their 8.1s im wondering what other people our getting for times thank you for any replies

 

Damn, that's a pretty quick Tahoe. Heads and Cam on an 8.1L would kick *** too! I don't know anyone with a Tahoe that has track times, but i am pretty sure there are some people on here with times in one. Hey how much does it weigh - approx.? <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />

There are a couple of guys over at Pacific-Audio that run good times in Tahoes and Yukons. I think they are running low 13's.

 

thanks for the replys i thingk it weights about 6000 pounds full of gas and with me in it
