Kinda what I said earlier, just with less hp. I totally agree. I could see the vette taking down the viper with those numbers but unless they shed weight on the ZL1 even 680hp isnt gonna make it a sure victory.

I don't believe that GM held back on HP because of the corvette. Hell they took the motor right out of the vette and dropped in the SS to begin with. GM has been putting vette motors in camaro's and trans ams for years ,and they were never faster. You know why? weight. The vette is much lighter so it will always be faster even with the same power. I believe cost is why the LS9 didn't make it into the ZL1.

What would the price be for the Zl1 with LS9 be? It has the LSA to keep price reasonable and the horsepower is more than most of us need..

Do you seriously think the suspension that the Mustang has will even come close to the MRS the ZL1 has???

I don't have any problems believing the Mustang will be faster in the 1/4 mile though...I just fail to see how Mustang is going to come close to competing with the ZL1 on the twisties though. And the lack of disclosure by Ford as to the times they were getting at Nurburgring is telling. You know if they had blown away the ZL1, that that video would already be up.

The silence by Ford on this is deafening...

It uses the same suspension technology as the Nissan GTR. So the MRS is a wash.

another tidbit of note

ls9 10.5lbs of boost= 638hp
lsa 9lbs of boost=580
5.4 9lbs boost=540
5.8 15lbs of boost= 662

so chevy vs ford at 9lbs a piece chevy wins by 40hp, I would contribute that more to the .8 diff in engine size than anything else though, not really more effeceint(sp?) or anything.

So again I think it all comes down to upping the boost and how much can each motor take before its unsafe. The LSA is at a disadvantage here since GM saved money by not going all forged internal like they did w/ the LS9 and Ford did w/ the 5.4 and 5.8.

At 15lbs of boost the LS9 would blow the 5.8 out of the water and the LSA should top it by 40-60hp, the LS9 can handle the boost no problem, not so sure on the LSA at least I don`t think I would want to run that much w/ out meth or something on an engine thats not completely forged.

Another thing is I don`t know why they don`t stroke the new 5.0 motor and forge it. Its a much better motor than the old 4.6, 5.4, 5.8 architecture.

I don't understand why GM didn't forge that motor. That's one of my disappointments with their approach.

That's simple. They can't. The 5.0 is at the maximum and cannot be stroked and possibly can't even be bored:

Because a fully populated Coyote crankcase is packaged tightly as coach airline seating-the already abbreviated piston skirts come close to the crankshaft counterweights-there is no room left for stroke increases.

I don't know that I would call the ZL1 a "track car" but it is better on the track than a lot of cars that are marketed as "track cars". Like you, the 1LE is closer to what I would consider the Camaro's "track car" model. I wish they had taken things a little farther though.

Fellas, do us all a favor and don't post in the new GT500 threads that pop up about this same subject. Then we can just delete them as they come, and not make this thread a mass of merges. Report them, and we will take care of it.

Thanks Camaro_Corvette... It is becoming quite a mess in here.

395lbs of torque at 1000 rpm???? Holy hell!!

[SIRLOIN]

So i wonder if the 662 hp rating is at the 6250 rpm and is not including the over-rev feature of 7K rpm?

When Hot Rod magazine had the 13 Shelby on the dyno they saw 670hp past 6250 rpm and it was still climbing...

Could this mean that with the over-rev feature we could see 700 hp?..

This thing is an absolute BEAST and is getting more interesting by the day...

Awesome job on the appearance mods on your 45th!





I have now seen it all, by the way. The VTEC argument is now being used by some Camaro fans. "It may not be as fast in the 1/4, but it's mad tyte in the twisties, yo!"

As dissapointing as it might be of all the news of the ZL1 competitor, it still doesn't take away the fact the Z is a badass car in it's own right...

No matter what happens when these two beasts go head to head, at the end of the day both camps should be happy and proud of what their favorite car maker brought to the table...

These are truly exciting times, and could quite possibly be the end of these high hp beasts...

Way to go Chevy and Ford!!! Hats off to you guys for making this happen...

This is from the press release

The combination of the new TVS 2.3-liter supercharger, twin overhead camshafts and four valves per cylinder ensures this stallion can breathe all the way to 7,000 rpm with the peak power production coming at 6,500 rpm and holding fairly steady right to the rev limit.

So I guess you can get up to 7000 with "fairly steady" hp numbers
