Going backto work this afternoon I get this guy in a LT1 Formula that goes by me and revs so I catch him in some traffic and I rev back at him. Well we end up going down the same 4 lane road thats usually pretty desolate so I drive a little slower than normal to see if he wants to run and he does. We started at about 45 mph and I was in 2nd. I pulled a little on him in second and then hit third and barely pulled a little more until I hit the rev limiter in third when I let out. I had maybe 1 1/2 cars on him from second all the way through third. He sounded like he had a catback and that was about it and Im stock. I guess time to start throwing mods at it now with almost 9000 miles on it.

Get it on a dyno and see where you stand...he could have had more than you thought.

if he didn't have anything more than a catback like you said, something sounds off. definitely get it dynoed. otherwise, i'd say he had something else.

My buddy with a 97 LT1 A4 w/no mufflers. He ran an M6 05 GTO and only lost by 1 car. I am not sure what is up with this.

Yeah Ive been thinking of throwing it on the dyno to see what its doing. Im pretty good at telling what f bodies have done to them by hearing the exhaust since Ive owned and been around them for 10 years but who knows. I need to get to the track also. It really doesnt matter if its a dog right now anyway as longtubes will be ordered within a couple of weeks and them the cams going in right after that. Then heads and nitrous so within the next year its going to be a nasty car.

Wonder if there is some power being held up in the tune...do the GTOs use the Vette-style throttle by wire?

I never had either of my M6's dyno'd but my 06 A4 GTO dyno'd at 322rwhp bone stock, with a tune 342rwhp and with magnaflow catback, and ported intake 357rwhp. M6's should dyno 15 or so more rwhp than an A4 bone stock. Torque management kills the A4, get it taken off.

Sounds about right to me.
and how the hell can you tell what his mods where? Ive heard timid cars that I later found out where heavily modded, and Vice Versa.

Noway a stock GTO and a very lightly modded LT1 is 1 car win for a GTO, 3-4 I can see but not barely 1. Im just pretty good at hearing these cars and knowing if they have a cam, longtubes, no cats etc.... I been around them so much.



Yes the GTOs have that gay *** drive by wire **** on them.

Yeah i agree, my bro has a 94z28 with a catback that has two small pipes coming out only on one side. No apperance mods and stock rims. It looks like a damn v6. But it also has a P-1SC and he has blown away many cars that looked and sounded like they would hand him his ***.

myv6rocks

my bolt on 93 z28 with 373 gears ran 13.2s.. are every 06 gto running better than 13.2s stock??

Drive by wire...definitely need to make sure the PCM isn't putting you too far out of the loop.

Im sure it is and Im waiting for my cam and longtubes before I pay for a tune.

my buddy had a 95 firebird Formula lt1 auto, with just exhaust and it ran a 8.5. They are fast, came with 3.73's stock, plus the gto's are so damn heavy.

brazenorangegto

Nope. Good driver yes but overall no and thats bone stok.

No stock f body EVER came with 3.73s stock, especially an auto. They came with either 2.73s or 3.23s if you had the performance axle. The M6s came with 3.42s.


I think you guys are missing the point, we didnt race from a dead stop we were already going almsot 50. If we would have went from a dead stop and let out by third it woulndt be a big deal. The whole reason all GTOs dont run low low 13s is they are ridiculousy hard to launch. Going from a roll takes the hard *** launch of the GTO out of the equation. Somethings not right about the outcome, maybe I misread what it sounded like he had but I highly doubt it as Im pretty good at it. Im going to either get it to the dyno or track and see whats going on.

Blu Dawg

Even though you where already going 45, that car weighs in around 2 tons... the weight still matter even after you are moving.

Don't be to hard on your car, 9000miles she is pretty tight. good luck

I know but believe me GTO should assrape a LT1 from a roll. These cars have problems with the tune from the factory and heatsoak and torque management issues. Ill dyno or teack and see what its doing.
