I am blown away.

The LS3s are for real.

Even if a strong LS2 does 355rwhp SAE, 40rwhp is certainly more than 36 flywheel horsepower.

From what I can tell, it seems the LS3 is around 450hp at the flywheel.

I can't wait to see some track times, especially the trap speeds.

Lou has stated that the LS2 cars typically do 360RWHP on his dyno. Therefore, the LS3 numbers we are seeing on LG's dyno are right in line with GM's stated power increase for 08. The truly impressive part is how well the LS3 heads and the new PCM respond to mods.

I don't see what the big deal is, there is nothing much on the street that can keep up with the LS2's already, and there is plenty at the track that will still blow away a LS3, so why is everybody .

Oh, and the wheels are stone ugly on top of it.

I wonder what to expect from just headers and a tune?

I agree that GM underated the HP figures so as to not lose more profitable Z06 sales.

I bet just a 6 HP gain for the NPP is part of the underating.

Can you dyno a LS3 with the base exhaust so we can see the difference just the NPP makes?

Finally!!! We'll be able to beat the new Mustang GT!! Even the GT with the hood scoop
Nah, all joking aside....I'm very impressed with those #'s!! That's over 460+ Hp at the flywheel going by 17%. I knew they would underrate this engine so we can all be surprised with the dyno/street results. Nice job Chevrolet!!

I agree they're ugly, but where did you get those butt ugly wheels on your car, your's are even worse, if you had kept your mouth shut, you wouldn't have shown your IGNORANCE

That's a somewhat valid point. While we know that the LS3s should be quicker than the LS2s we still don't truly know by how much.
And yes, the LS2 is still a beast in it's own right, I got on mine while driving around a bit today and it gets the job done quite nicely.
