I went to San Antonio Raceway last night and got some realy good results. I did take out the passenger side headlight and grill for ram air. All runs were done in 4awd and launched at 2400-2600rpm The first run i got 16.2 at 88 mph. Then i got a 16.1 at 88.xx. Im not sure if something is wrong with my 4awd but it was engaging late (usually it sense the rear slip a lil then engage the front, maybe its just mine). I then lowerd the tire pressure to 22psi in the rear. Next Pass was 15.93@88, then a 15.84@88, then a 15.79@89. My 60fts were from 2.4 to 2.3. My tb weight was 4725lbs. Im pretty satisfied with my times for the mods i have, which are dual intake, with a custom exhaust(bullet muffler dumped at the rear axle). Any feedback would be appreciate.

Sounds like some real good times. Did you wait between runs for a while to cool down, or do back to back runs?

as soon as i got there i started to run. Thats when i ran the 16s. Then i let my tb sit for an hour with the hood up, and lowered the tire pressure to 22psi in the rear. Thats when i started to run 15's back to back with no cool down. I first ran a 15.9, then a 15.84, then the 15.79, and then bascially consistent 15.84's.

What is the advantage of 22# of air pressure?

to get more traction, because i was spinning badly before and the a4wd would engage late. This corrected a problem and got my 60fts down.

sorry bout the delay, but this forum is always dead. Nope, cause it wont switch fast enough back to 2wheel after i reach 55 ( was told by a tech not to surpass 55mph on 4hi)
