Hello im from sweden... i just tested my GTA-89 at the strip today and don`t know if it`s good or bad?? The car is almost stock, 3" catback, dualcat (n10 option) thats it. I ran 14.87 and 93.9mph, 60feet at 2,27, and 1/8mile was 9,57 and 74.1 mph. It was kind of slippry and my tires are not that good but i was wondering about the trap speed...has some of my horses died since 1989... Is this good or bad times?? what do you guys with stock engines run?

Is this a 305 or 350 car. That 60' is hurting you, 94mph should get you closer to 14.5 if you can really hook the launch, like a 2.0-1.9 60'. You might expect if you dropped your 60' to a 2.0 at least a 14.5-14.6. Whats the stock timing advance at, if you haven't check it in a while, find out, you can usually dial the initial up quite a bit for a little extra ump, just keep an ear out for pinging. Most people get away with 10-12 degree's of initial advance with stock PCM tuning, maybe less if its really hot out, or you're running some crappy fuel.

 

This is a 350 car and the timing is stock 6 degrees

 

what was the weather like and what is your altitude above sealevel? those can really change your times

but so far that doesnt seem too bad of a time for a old L98 car. i'd like to see abit more mph with the catback mods but depends on the weather and altitude. if your in a higher altitude area with some hot air, that car may go low 14's at 97 down where i'm from in the somewhat mild air
