My freinds car is a mostly stock 03 GT auto just has nasty x-pipe and slp catback with magnaflow muffer and a filter got ti down to a 14.1@99 mph but sadly track prep was pure crap as it went from doing 2.12 60' to constant 2.2's.

I was pretty surprized considering its a pretty stock auto car. It has plenty of mph to go high 13's but the track prep wasnt there to get it to the ground it would spining the first 2-5 feet after the first hot run and the 60's never came back. There was a manual of the same year same mods and was only a tenth faster...... how sad.

 

ohh the memories....

there was a time when i only had a cat-back, CAI, and 70mm TB and the car would go 13.6 at 101. i had that good air in maryland.

 

yeah he really isnt into much like me he just wants a mid 13sec car he can drive every day. Its gonna get a set of 4.10's, j-mod,i allready added a cooler and a tune and we should see mid 13's with it and thats all he wants. But i will update everyone on it once we go to the track again and try to hit 13's the way it sits.

 

My 1999 GT (Auto Trans) ran a 14.3 Stock with only a flowmaster cat back.

 

fo sho!!

 

Wow... my fat *** car with a system in the trunk went constant a 14.3@98 mph. AND it had a mid-pipe, cat-back, 3.73 gear, accufab and JLT.

Then got it tuned with long tubes, cams and other junk... and went 13.3.

Then put 100 shot on it... and went 12.3.

hehe

 

Im trying to get him to go back soon before the weather gets too hot to make that 13.99 he wants.

 

I'll blow his doors off broke *** and all...lol

 

1/10th faster is equivalent to 10 hp which is the percentage of drivetrain loss (5%) from stick to auto. Not to mention a stick will launch harder in a stock application, not everyone is as great of a driver I am, and im sure the stick had just as bad of traction issues if not worse, as the auto friend. what do you expect from a stick to auto with similar mods.... half a second? lol doesnt work like that. not to mention the stick will never be consistant as the auto. i know i can range .4 in times when im at the track.

 

stick should be much faster considering the gearing and the ability to launch at a good rpm. SO yes i expect alot more then a tenth. Plus the fact that my car which has more weigth was alot faster with the same mods considering mine went 13.71 with just cai,h-pipe, mufflers, nittos. Yes im not impressed with that car at all.
