Who wants a wild rumor?
Rapid put down 553rwhp with a streetable 402 with AFR 225's....with more tuning left to do! With 25 more cubes, better LS7 12* heads (?), and the lessons learned from the C5R racing program, why couldn't the Z06 make 40 hp less?????

The math is there for an emissions-legal 515rwhp to be possible

I think it maybe more like 450rwhp though with 510-525 at the crank. If the engine can be reprogrammed, then 600 rwhp may be there with a cam, headers, and tune. The heads, intake, and tb are already there.

Don't forget headers either. It's making all that power on exhaust manifolds... the LS7 will probably gain like 40 rwhp with long tubes

as stated some people are confusing tuner motors with an OEM one. there is no way there getting 500rwhp in a 50 state legal 7 yr warrenty car. sure when you throw on mods the car will be a monster but from the factory 500rwhp aint happening n/a.

If I remember correctly, there were numerous posts over the last few months stating that the General was having trouble reaching it's 500hp goal (at the fw) for the new Z06 while keeping it emission legal.
Now, 515rwhp would mean around 600fwhp (assuming 14% loss with the IRS).
They had trouble reaching 500, and now, magically, they are at 600...
Come on guys...
My bet is around 440rwhp.

Just over 500 at the crank, whatever that translates to on a dynojet is what it'll have at the wheels.

GM sooo lied on that one; no way the '01 LS6 was 385 HP. That means an '01 would have 10 more RWHP than my SS with an LS1 intake, and not to mention early LS1 head castings.500 rwhp seems very unlikely... However the LS7 does have a lot of racing built into it... I'm thinking at least 450 RWHP. Dry sump, titanium parts, insane heads, etc. man I love this engine
I read an article yesterday on these. They are advertising 500hp from the factory! The article also listed all the items that were altered to lower the weight of the car. They said the carbon fiber front fenders had to be strapped down to paint them or they would just blow away. Carbon fiber bracing in the roof also. Balsa wood sandwiched between carbon fiber for the floor pans. Light weight and provides a sound barrier. I believe the article was in Motor Trend Magazine.
