AGREED, i own a 2007 GMC Denali and it has the 6.2L w/ 6-speed auto all i can GM did good. i raced my buddy's 03 mustang GT with cams and he pulled me 2 car up to 99mph where GM govern it, i knew i wouldn't win just wanted to see what it would do, i went to Denali forums to register and i was reading where getting in the high 13's with tune, air intake, and exhaust. i just got when i went on leave from Iraq so i didn't get to drive it much.

i know it has nothing to do with the G8 GT , just ging you an idea on how good the transmission is. not to mention that the LS3 is bad *** to.

Intake, Catback and tune adds 100 horsepower??

100 horsepower...absolutely! A good tune itself will add 50-60 gross.

No way in hell those mods give that much power, unless you go by what the manufacturer of the product says, lol. That motor is an LS2 based motor and believe me GTO guys arent getting anywhere near that much of a gain with just minor bolt ons.

The tune at GForce added 28 RWHP to my TA with just the tune.

A bolt-on, tuned and drag prepped G8 GT will run high 12s at 108mph. It may edge out and run a better ET than a STOCK LS2 GTO due to the launch and gearing of the 6A but trap speeds will be identical.

Well i would say that they might because those cars are tuned to run on 87 from the factory. So that in it self will make a huge dif right there plus the mods done i would say that close to 100 hp is possible

Yeah I did forget about that but I still find it REALLY hard to believe that very light bolt ons is going to make that motor make 460 hp. Using 20% drivetrain thats 374 rwhp which I dont see without headers and maybe even an intake.

I have only a mild cam, 78mm Fast intake with matching Throttle body, Corsa catbacks, a tune, good plugs/wires, and a aftermarket lid and my car put down 387 RWHP at Gforce. My 02' TA was only about 330 HP gross when it was stock, so yes it is possible.

LO I know you didnt just compare a cammed/intake car to a very light bolt on only car. With those mods I believe it would hit what you say.

The G8 has 40-50 more HP stock over the TA which would absorb the cam I put in my car, so most definitely would be close to the numbers.

Let just say I dont agree it would get that. Been doing this for a long time and have almost the same motor in my car and I just dont see it.

fair enough.....me too, been buying, selling, and building cars since I was 15 or about 28 years.

Deuuuce

Considering they pick up 4mph or MAYBE 5mph in trap speed, it's hardly 100hp....

I agree that the Goat should have won(even though I want a G8 GT), with those mods should have had no problem with a baskically stock G8 but if the GTO has a crappy tune then I can see why. My friend has a 02 WS6 that has a head and cam package from patriot, 3.73's, lid, LT's right...went 13.15(at 5900ft above with da and such)untuned, he then went to some local moron that tuned his can and dropped all the way to a 14.92 and never got faster, so he has to reflash his PCM now. S it's possible he has a junk tune. Just my .2.

GXPPOWER

heh a Tune alone will let loose alot of hp for the G8. remember the G8 is tuned from the factory for 87 octane if i remember right.

and G8Gt's have already run 13.3 range 1/4s so the races dont surprise me espcially with all the wheel spinning going on.

BlueGoat06

Check what they run, lucky to hit 13.9's, there are 3 that "supposedly" ran high 12's with bolt-ons. out of this 3 vehicles, there is only one driver who showed 1/4 mile slips. rest of the G8GT world runs mid to low 14's@100mph.

I can't believe all this owners suck ***** at driving an A6 car with a great 1st and 2nd gear trans. i'm pretty sure they'll improve once modded, the cam only cars are running mid 12.7's@114mph, but i'm sure with some tires those times would improve a lot.

The GTO lost the race by spinning at the starting line. What's interesting to me is the GTO didn't make up much ground on the G8 once it hooked up.......

Deuuuce

Your link shows you're incorrect about stockers. High 13s is the norm and virtually all over 100mph. Bolt-on and the key being TUNED gets them in the high 12s but apparently no faster than 108-109mph.

Something is wrong with the GTO. It was bogging after it caught traction.
