Well this is definetly going to be the last time i run this year. I need to rebuild my tranny BAD! started off with 16 psi running 14.31, uped the boost to 18 and ran a 14.1, same boost but a harder launch made for a 14.085. Then we cranked up the boost a little more to 21 psi and my buddy rob drove the car, and we got it to go 13.25 while launching with 6-7 psi. We would have been far into the 12's had the tranny not been slipping and flare shifting REALLY bad. everytime it would go to shift at 5250 it would rev to 6000 and that is too much for a stock buick motor. so we would always have to left off the gas, and then get back into it. This made for bad ET's, but i was pleased knowing that while letting off the gas twice i still ran a low 13.

Thanks for narking me out vanbibber, i like ****ing with people [img]smile.gif[/img] also if you don't know what a GN is then you need to jump off a cliff, espically considering you drive a GM product.1987 Buick Grand National drivetrain in my 1993 Pontiac Firebird.

I believe its the only car GM ever made that the same model year corvette had less hp and was slower then it.-Eric<br /><a href=\"http://www.cardomain.com/id/mustangeater82\" target=\"_blank\">2000 NBM V6 Camaro 5-speed</a> T-top <i>converted</i><br /><b>14.467@95.45mph</b> <i>$0 in mods</i><br /><i>The member formerly known as MustangEater8251</i>Comment
