I have a 99 formula six speed ls1 with a couple bolt ons, pacesetter long tubes,off road y pipe, slp exhaust, my buddy just bought an 04 gto 5.7 litre six speed, i was wondering what my chances of taking him were? Thanks alot guys

Irunelevens

Well considering you have the same engine in a lighter car, and you have a good exhaust setup, I'm guessing you will probably beat him.

You think so, i know hes around 350 horses, and me with a tune could be right around that range also, i thought my car was lighter, i guess we will have to take it to the freeway and see what happens, should i go from a roll, or stoplight racing? What would be a good next mod for me to put his gto to shame? an ls6 intake?>

Irunelevens

Well except for the intake manifold and other minor things, you basically have the same engine. He might start out with 10-15rwhp more than you, but you more than made that up with your exhaust. And yeah, you are a few hundred lbs lighter than a GTO.

what kinda race, i am going to get my car back tomorrow, i had my mechanic install my headers, and were going to cruise downtown chicago freeways, should i get him from a roll, stoplights, or would i take him regardless the race

Irunelevens

You'll beat him either way if you can drive at all. But you will beat him more in a short race from a stop, since you *should* be able to launch easier due to your live axle.

actually, i just raced my friends 99 ta, hes got magnaflo cat-back, cut out, lid. both cars are 6 speed. mines bone stock. went from 25-120. on the start i ripped away, then proceeded to miss 2nd (please dont laugh, thats never happend before and i almost cried alread =( ) but as he passed and the speedo kept crankin over i did nothing but real him in. take it as you will. ill be sure and tell you what happens tomarrow when i dont miss a gear.

yes please do, buddy, i was just curious, my buddy is getting cocky i dont want to give it back to him, but i honestly think i can take him, anyhow good looking car you got there, i was wondering off hand do you know if i do the ls6 intake if its a sirect bolt on, and if theres like a combo mod i should do with it, or is the intake alone all i need

ChocoTaco369

you have the same motor. you have 350 horsepower stock, too. GM underrated f-bodies on purpose in order to make the corvette look like a more powerful car, even though they have the same real horsepower and the f-body actually dynoes higher due to its solid axle vs. the corvette's hp-robbing IRS. you had the same horsepower STOCK as your buddy's stock '04 GTO. with your setup, you have about 400 crank horsepower in a significantly lighter car. as long as you know how to drive even a little bit, you'll destroy him.

ls6 intake is about as direct as it gets if memory serves me (its been a while since ive swapped an intake). you just have to change the gaskets. as for a combo mod? maybe tb bypass... you should invest in an airlid/filter and go ahead and do the free ram air mod while your at it. to get technical he does have a pretty decent exhaust from the factory (true duel ftw) and hes also got that fancy M-45 gearbox from the Z06. i still think youll edge him out but by no means destroy him. best of luck tho

You should beat him no problem.

My friend has an 04 gt0 m6 w/intake and we have raced many times. When i had a lid, cutout and ported TB i beat him by 1/2 a car from 65-130.(My car is also very heavy...stereo system doesnt help much

I then raced him after i put on my LT's and duals. So my mods were LT's, Duals, lid, ported TB. From 30-110 i beat him by about 3 cars. We then ran again but he had a 1 car jump from 50-120 and i passed him and put another 2 cars on him. His car is strong for being almost stock but i walk by him every time.

Yeah you should be able to take him. I ran a M6 04 GTO and took him, even gave him the hit. Went from a 60 roll.

awesome i didnt know mine stock came with 350 horses, is that really true, i forgot to mention i already have the lid, where can i get the gaskets? Hopefully we will be able to hit the streets this afternoon or tonight and get the race on, im feeling pretty confident ut if i lose i think its a respectable death, oh one more thing if i just had my long tubes put on would i be able to wait or should i get a tune

ChocoTaco369

yes, it's really true. GM underrated the f-body on purpose to make customers think you got a lot more power on a corvette when the power level was actually the same. they didn't want customers to think they were paying $20,000 more for a corvette when they could have gotten the same power in an f-body. the TRUE horsepower rating at the crank for an f-body is 345-350 horsepower.

you have about 50 horsepower more than your friend in a car that's more aerodynamic and weighs less. you should beat him pretty good. if you know how to drive your car, i see at least 3-4 car lengths. don't expect to destroy him like some civic, but you'll get him good if he's stock. what is your transmission and gears? the only way i see the race being close is if you have an A4 w/2.73's. if you have an M6, you'll get him real good.

either they come with or you can get a new set from your local dealership for a minimal fee. that or i think you can use the ones from your old intake.

yes i have an m6 and i beleive my stock gears are 342's, this is good to hear, i like his car alot, but he just thinks its god, ill teach him a lesson tonight, on i94 (wide open freeway of chicago) ill let you guys know thanks alot by the way

Irunelevens

Good luck with the race, but I'd still take the Goat (if it's an M6)

ChocoTaco369

you own a mustang GT. due to your obvious poor taste in cars, your opinion doesn't count

Irunelevens

You're sure a funny guy... shame you could only pull a 13.6 with over 300rwhp . How's it feel to have an LS1 running the same times as LT1s, and still act like a badass?

Edit: And I'm just gonna come out and say it; the 04-06 GTO was (besides the Corvette) the best car GM has had in this country in a LONG time, and I'm glad they are again using a Holden basis for the new G8, which also looks quite promising.
