sorry to kind of change the to pick but everyone says that the ubend in the older Gp is bad to the performance of the car. Now i have a headers and i have a pretty big u bend were the headers end those this also affect my cars performance or no.again sorry i am just confused.

what kind of headers do you have?

SLP, SSAC, Speed Daddy's...they are all the same...they all have that low lying bend 3" DP that looks like an egg...

Yeah I have the SSa headers

ran 16.115 at 85 mph hahahahah she didnt even get out of second

U-Bend delete and maybe a better launch and it would have been 15's...what were your 60 foots?
06-30-2010
my slips are in the car, ill post them on here tomorrow, but she was consistent, made 10 passes, 85 mph every pass, 67 mph in the eighth.

That just means you needed to be harder on it if you've never been before...
Turn off TCS? Power brake it at the start? Lower tire pressure a tad? Take out the headlight? Remove all the crap in the trunk?

TCS made no difference on my runs, car was empty, tp was at 35, didnt remove headlight and preloaded it at 2 g's

seems about right for a gt with an inexperienced driver though. maybe the track didn't have great traction, or temps/humidity wasn't great. like blue said, you're probably a good launch away from 15's

i go up every other wednesday, my buddy has a 9.2 second chevy nova he brings up on fridays that is just sick, 9.2 on motor

TCS pulls timing regardless...probably just enough for that little push you need to be sitting in 15s
07-01-2010
so turn tcs off?
07-01-2010
yep...it could help you. Either way it definitely won't hurt

in this case it means getting a good launch and controlling wheelspin. it's easier to do in a car like a grand prix with hardly any power to get off the line. but the clock starts when you trip the sensor off the line, if you're spinning the tires then you're not going anywhere. think about the dragsters and funny cars that fun like 5 or 6 second quarters, there's a ton of wheelspin and control issues. it's not just flooring it and hoping for the best

Thanks for ruining it for me...I've been doing it all wrong then.
