Ron Meegan, the assistant chief engineer for the new 2009 Chevrolet Corvette ZR1's supercharged V8 (and formerly a member of the original ZR-1's engine team from 1990-'95), says he expects that once the new car's supercharged 6.2-liter V8 is certified, it will produce "greater than 620 horsepower at 6,500 rpm and 595 pound-feet of torque in the 3,600-to-4,000-rpm range, depending on some last-minute tuning items."
Whether the ZR1 is rated at 625 hp or 633 hp or whatever, it won't just be the most powerful Corvette production vehicle ever (including ones measured by the grossly overstated "SAE gross" figures of pre-1972), it won't even be close. The power produced by the ZR1's LS9 engine will be roughly the equivalent of three 1980s-era Corvette small-block V8s bolted together. It'll produce more power than the Corvette C6.R that races at the 24 Hours of Le Mans.
Think of the Corvette lineup in Porsche 911 terms. The base coupe and convertible Corvette are buttstuffogous to the standard Carrera and Carrera S. The Z06 is the GT3 — the loud, hard-core choice of the performance junkie. The ZR1 is the Porsche Turbo. It's devastatingly fast, but it's also intended to be civilized.
Take a close look at that 'intake'. It is a single unit, integrating the Supercharger, Intercooler, and Intake Manifold. I guess they didn't want to waste any space. :hick:
*edit* Lots of good pictures that are just too big to post here. There are two of the top and bottom of the SC unit as well. http://www.leftlanenews.com/chevrolet-corvette-zr1.html

That is so cool!
Glad to see they will revive the "ZR 1" name.
I have always wanted a 1990 ZR 1 but now it is not practical seeing as how expensive replacement parts are.
Still, the 1990 ZR1 will always be one of my favorites.
I bet those wheels on that new ZR1 will be a pain to get the brake dust off of.

Yeah, the Chief Engineer says in that article "If a buyer really wants them, he can get chrome wheels on it," although he's letting us know that he would never do such a thing and he thinks you shouldn't either.
More on the LS9. http://www.edmunds.com/insideline/do/Features/articleId=124018?tid=edmunds.il.home.photopanel..1.*#14

Wow, They are make it even faster. I would almost say thats stupid. The car bairly sticks to the road now. Well the Z06. Now with even more power, WOW! That thing is going to lighting the traction control up. But very sweet car.

They say it won't be any faster to 60 than the Z06, because that is already traction limited. But Quarter-miles and 0-100-0 times will be very different.

Yeah, basically what you will see is more wrecks per 100 cars sold to the public.
I remember hearing about how many people bought the Z07 Vette as well as the Viper and wrecking them because they "thought" they could control those cars.

Z07?:confused:
I think it's more about how may people think they can get away with turning the traction control off. People need to realise that when you see the pro's do this, they're not on public roads!

WOW ! the single unit Supercharged/intercooler/intake is one of the most interesting engineering pieces i have seen in my life. They really made a superb job. I am seeing this engine in the next camaros or firebirds......ford, wake up !

How about those brakes. 15.5" fronts and 15" rears.
Also if (according to the Edmunds article) Z06=GT3 ZR-1=Turbo ?=GT2 Can't wait for that one :D

Yeah, those positive displacement screw blowers can make some serious power. Ford? Easy as bolting on a similar supercharger to a 3V.
Don't underestimate the Fords with similar blowers! Just because they are not offered factory (heck, it's probably a lot cheaper to do it aftermarket anyway)...

Worlds First positive displacement 804 HP 3V Mustang GT
Kenne Bell has taken the 3V 4.6 to a new level. S.T. Motorsports tested the latest Kenne Bell 2.8H Supercharger and Mammoth inlet on their '06 Mustang test car. It made 804 HP with stock exhaust and manifolds(no headers). Guess how much is left? Headers and exhaust are next along with tests on an automatic transmission. The Kenne Bell 2.8H with the new Mammoth Inlet System (filter, meter, huge 4 1/2" ram air inlet tube, dual 75mm Kenne Bell throttle body and Mammothfold) was good for 204 HP! ( 804 vs. 600 = 204 hp @ same boost) 60 lb injectors, stock rails and lines, FRP GT dual pump kit w/ KB's exclusive dual Boost-A-Pump. Kenne Bell Boost-A-Spark was the only ignition modification. The Boost-A-Spark fired the plugs even at 28 psi. Engine is a 4.6 built and tuned by S.T. Motorsports. Adam Montague will offer kits with 25 lbs (804hp) competition and 10 psi street with only a pulley change. The goal was 800+hp with stock exhaust and headers - just like our '07 Shelby GT500. It appears Adam's 804 hp 3v does, in fact , make the same power as our 801 hp Shelby GT500. The Kenne Bell kits on both cars are almost identical. Both Mammoth Inlet Systems flow the same on our 1000 HP flow bench - and the 2.8H superchargers, boost, timing, AFR etc. are all the same. You gotta love that little 281" 4.6L 3v. Kits will be available in 90 days and pricing is coming soon.

I'd say the Z71 Vette fills the GT2 spot now with it's uprated suspension and 436HP.

I'd say this is the GT-2, since you can't get an AWD Vette.

THe downside is that this ZR-1 may perhaps make the Corvette into an even more upscale marquis than it had already become as of late. Gone are the days when the wrench turner who worked at the corner station could afford one.

That wrench turner back in the day could afford a small-block Corvette, but never the L-88. A track worthy Vette for those with the extra money isn't a new idea. It's just been a while. Remember how expensive the first ZR1 was?

Correct. Now the base model is out of reach as well though....

Good point. It's still an amazing value when compared to other sports cars around the world, but not compared to the average middle-class family car.
