My shop had a track rental at Lebanon Valley Dragway on friday and it was my first time ever racing at a strip. I brought my 91 AWD with a k&n, boost controller, and fuel pump (still stock exhaust and no punched cat). Best time on pump gas and 17psi was a 13.6 @ 94 i believe.

Soooo, after that, i dumped the exhaust after the cat (would of done it before the cat but the bolts were too rusted LOL) and tossed in some race gas. The 116 octane clogged my cat and only let me run 16psi :mad: but here is the best i could muster

60' - 1.723
330' - 5.391
1/8th - 8.321 @ 82.34
1000' - 10.974
1/4 - 13.229 @99.59

On the way back home from the track, i stepped on it while i was on the highway and blew a hole right through the cat and it was making 20-21psi. Grrrrrrrrr!!! I wish it did that at the track, definately could of got some 12s in. Oh well, maybe next time.
 
how does race gas "clog" your cat? usually the lead in race gas just coats the inside of your exhaust including the crystals in the cat. i'm not sure if there's a way to clean it out.. but i wouldn't say that the cat gets clogged.
