might as well tell us what u did
after all the advice thats been given!
Car changes since last time at track: front and rear poly mounts, boost gauge/ladder tach, wideband.
I lowered my tire pressure to 22 psi, which I felt a difference, but my quickest run had a 60' that was worse than my best run from the last time I was at the track...
Last time best run (11/8/08) This time (1/31/09)
60' 2.300________________________ 2.322
1/8th mph 80.43________________________81.4
1/4 mph 103.75_______________________103.46
64 degrees, 40% hum.___________48 degrees, 30% Hum.
Same tune, and no race gas this time. (I get a little kr as my IAT's get higher so that's why I added it last time). I think the lowered tire pressure didn't help at all that run as far as my launch was concerned (first run, still getting the rust off), but I believe it kept me from spinning at higher rpm's and the poly mounts definitely killed any wheel hop. I added the 300' time because there is a clear difference in how power was applied higher in first and into second. All day I was able to ride 1st gear wot at higher rpm's and had never been able to do that before (keep in mind 1st gear boost is limited).
Honestly my times were very inconsistent, and so were everyone else. We all agreed the track was too cold, the only reason I think my best run was that good was because A. My IAT 2's were very cool and B. I was the first car to run on the track with fresh vht.
My second best run of the day was much later and only a 13.9, but it was again right after they sprayed more vht.
