The LS9 won't be getting its final certification until about March, but so far GM has put over 6,800 dyno hours on the new engine. They have run an engine for 100 hours continuously at wide open throttle...
Very Cool. Hmm. I wonder if Chevy's competitors are doing that?

I don't get why everyone says the 7L isn't strong enough for a blower, yet lingenfelter turbo's them to 850+HP an offers a 2yr/24K warrenty.
Lingenfelter wouldn't do that if they broke. One side has to be wrong.
Two things I'd change.
Instead of the clear cover have the intercooler cover come through the hood a half inch giving it the apperance of an old school shaker.
Then put some slits in the top so it cools better. Like the spy pic.
Other thing. Instead of one big injector and an ECM/wiring nightmare in the back. Use two injectors like the LT5. Or one smaller injector for idling-3K then the second kicks in. Something of that nature.
Other notes of intrest.
It uses the same exhaust mainifolds as the 7L.
We all know a header swap on one of those is worth a ton of power.
It uses a cam with less lift and 27% less duration then the 7L
Again we all know a cam an header swap on an Ls7 can put you at 650hp.
So now we are taking an engine already at 650hp that's using the same exhaust manifolds and an even smaller cam.
So cam, headers, pulley, tune = 850hp for those that do it right.

I like everything from the windshield forward.
Don't like the scoops in front of the rear wheels or the rear "wing" (lip) if you can call it that.
Should have had Larry Shinoda style it...or at least the rear.

Remember when we all thought the C6 Z06 was the ultimate sports car? This is overkill, but I love everything about it. It's a 599 GTB with a $175k discount.
Other thoughts:
I love that it uses the magnetic shocks.
Wheels look great. And I bet this thing could stop the rotation of the Earth with those brakes.
"Skull" logo on the intake is a nice touch.
And for the record, I love the hood window.

...engine tested for 100 hours straight at WOT.
Sweet. I like how GM is going after the durability of this engine. I'd hate to see this thing get released and then have to call a bunch of them back like the Ford GT.

um lol.. i think GM wants the engine to last longer than 2yr/24K on the ZR1.. i'm pretty sure this thing will be warrantied for 5yr/100k like the rest of GM powertrains

The 300-400 extra pounds over the Z06 is a huge surprise and disappointment to me. Maybe not to others but I would have assumed they'd be able to keep the weight to about the same as the Z06... extra weight reducing countermeasures to counteract the weight of the new motor, larger brakes, etc...
Still, they claim this will take the production car track record at any track out there. That's a pretty bold statement and if it's true and yet this car is still more comfortable and daily drivable than the Z06 then this is huge for GM.
Oh... FWIW I hate those wheels. Everything else looks great though.
