I am thinking about buying a 04 Goat and am curious as what HP and TRQ numbers they make at the ground in stock form with a auto and a manual. If anyone has numbers would you post them. Thanks

Auto = 305-315rwhp

6sp = 325-330rwhp

some A4 cars are a little lower than that even. my 04 a4 car did 303 to the wheels.

How come some of the auto's you say make even less than that. The car that I have found is a auto car and with the numbers that low and you say some are even lower maybe I should hold off for a manual. My only plans for the car are a set of longtubes,K&N intake system free mods and a 150 to 175 shot.

On a DynoJet a stock A4 04, no tune no nothing will typically average 285 - 290 rwhp.

My baseline dyno (stock + LPI CAI) was:

Run 1: 297.0/326.2
Run 2: 302.4/325.1
Run 3: 302.3/326.7

The typical tune coming from the factory on the 04 was crap, I was lucky and was actually pretty well tuned. Most cars had spark plug gaps that didn't even match.

An A4 has about a 17% loss from the crank. So 350 * .83 = 290.5rwhp
So with my current bolt-ons (LTs/CAI/exhaust) I'm at about 385hp *.83 = 319.55rwhp

Manuals have more like a 13 to 14 % loss...but all things equal are slower in the 1/4.

he's talking LS1 not LS2

If your gonna spray it I'd go with the A4 for sure. don't let the #'s scare you stock my 04 ran a 13.59 on stock tires with 3000 miles on it.

Those #'s are too high for an 04'. They look more like LS2 numbers. From what I've seen the 04's dyno slightly less than an LS1 f-body because of their independant rears.

My stock 05 ls2 did 337 to the wheels. A4 car too.

They're not right for a stock LS2 either....too low. The numbers I posted are the correct ones to expect for a stock 2004 LS1 A4.

So the rearend setup really eats alot of the power. My stock 99 TA with bolt on minus exhaust and headers made 311 and 325 on a dyno jet. It just seems hard to believe that the rearend on the GTO's takes up that much power.

LS1 GTO's will dyno lower than LS1 F body's. The tune is more conservative from the factory, and the IRS eats up a little more hp.

I've got a 2004 M6 for sale...

That is really a suprise to me about the rearend eating that much. What are you wanting out of you GT0 and if you don't mind telling me why are you selling it?

i have 2 friends one made 295hp to the wheels and the other like 296hp there both 6speeds no mods same color if that matter lol but it doesnt they bought both a month apart

YOUNG

iTrader: (3)

That really just seems a little low for a car that is rated at 350 at the crank from the factory or am I just looking for to much from a factory car?

1MEANGTO

too much why buy a dyno queen just get the numbers you want

1MEANGTO

the little bigger cam makes around the same power as a 2002 ls1 but the car is heavier

YOUNG

iTrader: (3)

Yeah I agree about not having a dyno queen. I was just wanting real numbers from people that have the cars. I do plan on doing some mods to one if I get one,but I wanted to see what numbers I would be starting with.

My 2004 a4 GTO was 289 rwhp stock.

I would like to thank everyone for taking the time to answer my questions about the GTO. I do believe that this is the car I am forsure in the market for. Thanks again!!
