That looks like hell
C4 speedster is the way to go. Here is the 700+hp ZR1 speedster
Much nicer in my opinion.





needs different wheels, but other than that it's perfect.....

The Callaway C4's were their best cars... innovative body lines, turbocharged monsters... It all went downhill from there. :(

I think its funny that the C4 turbo cars made the same power that the current C6 C16 models are making... but they did it 15 years ago! :crazy:

:agree: sledghammer twin-turbo = 880 hp.....probably my favorite corvette by the way

$305,000 for what is essentially a rebodied C6 Corvette?:crazy:
No no no. It's not a rebodied C6! It's the illegitimate child of a Mercedes' and Chrysler's drunk night out. And I think the Mercedes and Chrysler were both men too.

I think that's a testament to the limit of these motors. You just can't go any further without hurting reliability.

After the SS comes out the only thing left for increaseing performance without hurting reliability will be to find a way to shave major weight alla Ferarri, or a significant change in the power plant design...

...and thats only if GM thinks there's a need to continue the HP war.

Bu the way the glass work on that car is awesome.

My favorite color too.

Ummm, you're kidding right? :lookinup: By "these motors" are you referring to the LSx series...? Because if you are, reliability is one of it's greatest virtues. There are more LS1's, LS2's, LS6's, and LS7's running around with 600+ RWHP than I can count. These motors are reliability defined, compared to the other stock engines out there in sports cars today. Sure, you can't run 800+ HP on stock LSx motors without beefing them up, but the Callaway C$'s that made that power were far from stock.

I think you misunderstood the point I was getting at. The old Callaway turbo cars were making just as much power 15 years ago as their supercharged cars are today. This has nothing to do with the engines and everything to do with their engineering and the fact that their turbo setups were better than simply ploppin on a effing maggie blower and calling it a day. They have increased their profit by offering an inferior and more simple forced induction power adder. They know now that they can make more money selling the name plus a shiny blower that adds a whopping 130ish HP than a better (less profitable) turbo set up... :down:

They want the cars to be reliable so they limit them to a level where they are going to run fine and that's that... The turbo set ups were just so much nicer...

When I said, "these motors" I was referring to OHV in general.

Your right there are plenty of LS' out there with 600+ HP, but you even admit in your statement thats pretty much the limit while maintaning reliablility. As you said above you can't run 800 HP with out beefing it up which kind a falls in line with what I said, about a design change.

You even said, "they want the cars to be reliable so they limit them." They can't push these engines much further with out in your words "beefing them up."

Now I'm curious about the old turbo's, what was it about their engineering that you liked so well?

I cant think of any reliable 600BHP motors on the market at all.

Thats just it, whether some will agree or not, reliability is in the eye of the beholder. Are you going to drive your 600+ HP car 5k miles a year? Then its probabley reliable. I drive 1200 miles a week at times. I doubt that engine would stand up to that for very long.

My LS2 is making 600 RWHP and is daily driven 8 months out of the year. I have been at this power level for almost a year and 12,000 miles. Knock on wood or whatever, there has been no issues at all so far. I think that 90% of the reliability lies in how the car is tuned. Afterall, these things are controlled my a tiny computer, and the wrong tuning can destroy even a stock motor quite easily.

Hey Tom nice ride, your pics are cool. Where the hell are the turbos in that thing. I thought the engine pic was preturbo until I looked at the engine cover. I like how everything is tucked away all nice and neat, a real sleeper if a vette can be a sleeper.

As far as reliability goes Its like I said, it depends on ones definition. I'd want to be able to put a car like that together put 15-20k on a year and not have to touch it again outside of normal maintenance for at least 3 no more than 5 years. Now I know In cars with 600+ HP that may be unreasonable, but that is my definition of reliability. Now that doesn't mean the freak water pump failure or something couldn't happen. Hell I have a 2002 minivan right now with a bad pump at 65k. I'm talking about a collapsed lifter, spun bearing, or any other major failure.

What one man considers reliable another calls a grenade.

Thanks, Rick. :thumbsup: The turbos are at the bottom of the manifolds (where the shorty headers/cats used to be) one on each side of the oil pan. It basically looks like an OEM application. It's a clean and stealthy install, which is cool, but I'd be happy with a little more 'bling' if you know what I mean. :D

No way man not me, that thing is perfect. I love cars that keep their secrets well.

Hey I got a great idea, you build one with bling, and just give me the other one, I'll take that plain old girl off your hands for ya.:D
