GM powertrain Engineer speaks about the LS9

http://www.autoblog.com/2008/03/04/v...r1-ls9-engine/

Hit the link for a video

Quote:
The ZR1 Corvette is one serious piece of American metal, with the athleticism of a track star and the brute power of drag racer. While light weight materials, magnetic damping and 15.5-inch Brembo brakes sounds impressive, the real meat lies under the hood of the fastest ever production Corvette. GM's supercharged 6.2L small block V8 packs at least 620 hp and nearly 600 lb-ft of torque, and its duty is to finally put the Corvette into the supercar club. We were lucky enough to spend some time with Ron Meegan, the assistant chief of GM's small block engine program, and he gave us an engineer's view of the supercharged LS9 engine. Hit the jump to learn why GM didn't use the 7.0L V8 from the Z06, why the Eaton supercharger is so special, and whether or not GM is being modest with the ZR1's projected 620 hp rating.

The LSA is really what I am hoping for. I think we can get to LS9 Power with a pulley and maybe a cam change. Not to mention all the bolt on mods....

I think a pulley change would get us there. I can't remember the cam specs' on the LSA but I know the SC is smaller, however, the intake/intercooler is more efficient on the LSA than the LS9, from what I've read. Maybe LS9 needs a bigger SC to make up for the inefficiency of the intake as opposed to LSA.

I'm thinking pulley, tune, intake, and catback will be pretty close to LS9 power. Let's just keep our fingers crossed...

I don't think Camaro will come from GM much more than $45K if anything. We've been told again-and-again it wil be comparable to Mustang, so...

Ah come on. There's a ton more capability in the ZR1 than the Camaro. The chassis alone...

The LSA has a 1900 and the LS9 is a 2300 supercharger. And I agree those Simple bolt on's should do the trick. I'd like a msd box and wires, headers, and CAI. I'm thinking that should about do it. And if not add a Cam and retune.

Having said all that, For 45K We better be talking LS9 numbers.

I hear ya' on this. I wouldn't complain if I had the $$$. I don't think anyone in their right mind would pay $70K for a Camaro, LS9 or not. I love the car and all, but that's almost crazy.

That's not to say I couldn't find a way to spend another $30K in modifications on a $40K car though. I just mean a stock $70K car.

Like you said: horsepower is money. Keep the Ti rods and bigger SC and I'd be plenty happy with an LSA.

he he he. I like the ZR-1. And LS9. One cool thing that I noticed in the video is that the supercharger whine has been nearly eliminated. So all you hear is 600+hp beastlyness. 'nother cool fact is that the brakes were developed for the Ferari Enzo and FXX. The ZR-1 wont be the fastest car in the world, but it won't get embarassed on the track by Enzos either. I don't think there is another car that sells for ~100k that can make such a claim. Makes you wonder what all that F1 derived tech is good for.

I read in Camaro magazine that since the Corvette has the LS9 that the logical step down would be the LS7 for the Camaro. I am just going on what the mag said. I really dont know much about the line of motors so I am just a noobie on that. Does that make sense that the Camaro would have the LS7? They said that each year the Camaro basically got the previous year Corvette motor. :notheadlights:

Yeah but the LS7 is the Z06 motor, not the standard motor, being the ls3...furthermore, the ls7 isn't going to happen...thats a 30k engine by itself... SO unless the top of the line Camaro is going to start at around 50k I doubt it will happen.

Sounds good for a Super Beast though, like the ZL-1

No more LS2 and LS7s. It seems like GM is moving toward different S/C'd 6.2Ls for high-end models.

^ I hope so. I'm really jones'n to find out what they will be. Even if we don't have a near 500hp beast I can at least start looking at ways to get there.

I'm starting to get that twitch I get when we go a while without anything new....

I'm with you. I've never owned a new car. My wife has always gotten them, so I think I've just been waiting for the right car; and Camaro is the right car

Here is a link to RPMPlanets that also includes a video of the differences between the LS9 and LSA.
