Attention 08 owners!
Just wondering if anyone is thinking what I'm thinking. OK, we have a LS3 which is the same motor in the ZR1 minus the forged internals and the titanium valves in the heads.
Has anybody thought about pulling the motor putting forged internals in with the titanum valves, and using the LS9 supercharger or any other boosted system? I mean we are talking some serious, I mean serious power. The 03-04 Cobra mustangs with their forged internal bottom ends do decent with turning up the boost, right now 850rwhp is the record on a stock motor(nothing done to it all, Mike Palugi car). So are LS3s with forged internals would be just as strong or stonger. That Cobra motor tripled its power,but had twin turbo boost. If are motors which would essentially be the same as the LS9 tripled its power. Get my drift, of course the entire drivetrain would have to be beefed up, but the potential of this car is awesome.
What are we wating for? What do you guys think?

Another consideration might be to do a po-boy version - install the LS9 blower, use only about 60 to 70% as much boost, and install thicker head gaskets to lower CR a bit. Wonder if that would work ?

Callaway is doing it with the 2008 LS3 and quoting 580HP for their Supercharger package, 650HP for their C16 package. They have been doing a lot of test, tuning, and validation for their 2008 Supercharger package and just did a press release with the numbers.

"OK, we have a LS3 which is the same motor in the ZR1 minus the forged internals and the titanium valves in the heads. "
and minus the block and heads and oil system and intake and exhaust and fuel system and... I'm struggling to think of many common parts between the LS3 and LS9. They share bore spacing, most dimensions, and cam location... but that block and heads for the LS9 is quite revised to pass validation at 620 hp. From what I've read, block strengthened 20% and heads 24%.
I'm guessing these "validated" 650 hp tuner deals use a bit different validation process than the OEM.

I have the LS3 with a 4.100 forged crank, scat rods, Diamond forged pistons and rings. It's L92/LS3 heads are CNC ported flowing 360int/280ex. Even with a compression of 10.9 a blower does sound interesting. In It's present condition it makes 525rwhp/500rwtq. It displaces 427 ci. The only drawback is the cam isn't really a blower cam. It's set up for N/A. I do know Andy Green has his new LS3 A6. He's doing it in stages. Blower, blower and headers,and finally blower , headers, and a cam. I'm sure he's working on as we speak,and he's leaving the internals alone. I'm sure he'll post each stage as they are completed. Something to look forward to.

The LS3 block isn't as strong as the LS9 block -- they are _not_ the same "with just different internals".
So the statement that "LS3s with forged internals would be just as strong or stonger" is inaccurate.

Guess I got a little excited about it being just as strong as the LS9, but close.When we put the LS9 charger on that takes care of the intake. As far as exhaust I'm running full exhaust right now anyway. The fuel system is going to have to be upgraded better than the ZR1s anyways do to the power I want to make. What I'm getting at is that it's the same cubic inches/heads and the potential can be the same with some money spent, minus the LS9 having a stronger block/heads. All with a fraction of the cost of the supercar I would love to own one day. I will have to look up this special alloy material I have heard about.

Don't forget the internal oiling system and the dry sump. Your LS3 without those things may not live very long. I'm sure GM didn't design and install those things just for fun.
My guess is that you'd be better off waiting to see if you can buy a crate LS9.

How about the link for this. I've been waiting on the LS3 blower setup.
