is this good or average 99 ls1 automatic trans am longtube headers, y-pipe, slp loudmouth, slp ram air , and tune only upgrades i ran 2.0093 - 60ft , 8.8053 - 1/8th mile at 84.14mph. is this good or average? i was just curious. thanks for any input
That is actually not that good really. That is roughly a 13.6-13.8 1/4 mile time. That would be average for a stock car, you should be around a 8.5 or better in the 1/8.
But DA and weather plays a big part and that is why timmy jones is asking.
That 60' could use some work as well. Get a 1.8x 60' and you will be doing good.

Those times sound like they just reflect the 80 degree weather and the fact you had the a/c running, compared to the 1/4 mile times. Probably had a lot higher DA at the 1/8 mile track.

1/8th mile calculator says its 13.6's which means there is something wrong. Should be running a bit stronger.
Was the tune mail order or a dyno???
Case in point, my car. 2002 M6
Add a SLP Lid only 324 RWHP, stock tune
Add Dynatech headers, catted Y and Corsa + 12 bolt w/ 3.42's 325 RWHP and pulling timing when dynoed
Add Dynotune makes 355 RWHP

totaly disagree with you. i ran a 12.57 @ 110 in 1/4 mile. if i had a scanner i would upload for proof from my time slip. altho my 60 ft is still close to the same at 1.98 , the 1/8 mile i ran down in ms 80 degrees out with a/c running. was my first time on a 1/8 track thats why i was wondering if those were decent times
I'm going to say no way on this one ^. The only way is if this was a DA corrected time or something like this.

dont think they are a very good time either considering my buddys old 95 formula with a muffler delete shift kit and 3000 stall ran an 8.7 all day long with both of us in the car an ls1 car with full exhaust and lid should easily run low 8's

like i said a/c was on in 85 degree weather . i shouldnt have even posted this thread cause all its doin is pissing me off. i know my car is faster than that i was jw about that time i posted. i only posted it cause ive never ran 1/8 mile and was wondering wat to expect. a/c ON in 80 degree weather will make a huuge difference.
