Hi,
This is for a friend, he owns a 05/06 M6 GTO. He is wondering (I'm pretty curious myself) if it is possible to get 600 naturally aspirated rwhp out of his LS2. The funds available are $7k and he does not want to do a swap. He wants to keep his original drivetrain.
I have read a ton about boosted LS based motors making 4 digit numbers all day long but you really dont hear much about anyone running naturally aspirated. Can it be done? How? What parts would you guys recommend to make this happen?
Can you guys post some parts combos that you think would him to or close to it?

Thanks for the info, we appreciate it

Simply put... no. A more realistic goal would be 450 RWHP N/A then a 150 shot to bring it to 600. That could be done easily with an LS2, and for much less than $7K.

The only possible way to 600 RWHP N/A would be with 427 or more cubic inches.

uh no. as latch said...cubes. check the dyno section. 44X build just put down 600+.

i make about 430NA on a mustang dyno with my H/C/I a4 ls2.

im thinking youre going to need more cubes and a dynojet to get what hes looking for.

In a max effort build you may get 500-520 but definitely not 600.

I cant believe 600s not possible. I thought for sure it would be possible, considering the aftermarket available for them.

This came in discussion when were talking about foreign autos, Audi, BMW and more exotic. How such small displacement motors make 5/600 in N/A form. I know its like comparing apples and oranges but it was a fun conversation.

Those cars won't put down 600 rwhp. They don't even make 600 hp at the flywheel. I don't know of any production engine that makes 600 hp in n/a form. The only car I know of that comes close is the Pagani Zonda F which has a 7.3 liter V12 and it makes 594 hp and 560 lb-ft. That's a 12 cylinder engine with over 440 cubic inches and it still came shy of 600 at the flywheel.

Like I said, a more realistic goal for an LS2 is 450 rwhp, which is well over 500 hp at the flywheel.

As mentioned none of those make 600 to the wheels, all production cars are rated at flywheel hp. So if you want a 600 flywheel horse LS2, then yes, thats possible (that would be 510RWHP give or take).
But honestly why would he limit himself to stock displacement when he can go up in displacement without sacrificing anything? Why not bore/stroke? Its still the original drivetrain.

Im splitting hairs but the Enzo makes 650hp, the new Lamborghini Aventador makes 700, and the Lamborghini Murcielago LP670 makes 670.
All are ridiculously priced exotics revving sky high to make that power though.
Same later model Molser cars have a modded LS7s making 600hp, and they are technically production cars.

Doh, it appears my supercar knowledge isn't quite up to date. I stand corrected!

put a direct port nitrous on it w/dedicated fuel pump. < $2000. get a well built short block ~$5k. Done till you destroy your driveline. 600 N/A is going to require ALOT of $$ and testing.

And why doesn't he want to change the drivetrain? Seems like he wants a 600 HP car just so he can say he has a 600 HP car. He would be better off making 450ish and getting a rear end, clutch, suspension, etc. That can actually handle the power. If he doesn't 1. He is going to spin and have trouble putting it to the ground. and 2. If he does get it to the ground things are likely to break.

Thanks for the info guys, we appreciate it.
I'm almost posotive he does not want to use N20.
I dont think he has a problem pulling his motor and doing work to it. He doesnt want to swap in another bigger motor, he mentioned something about a 6.2.
I agree, I had mentioned the same thing to him about beefing up his drivetrain before doing anything. Things will break when power is added, N/A or Boosted.
