For the love of Pete, somebody PLEASE tell me the pistons aren't still hyper-u-xplode-it.

Forged rods????

Red... please talk to them... make them understand... $500 for forged rods and pistons... all of us C6 Corvette buyers will pay it.

 

Pretty much hot off the press, eh?

Looking good!

As I understand it, hypereutectic pistons are:

a.) Cast
b.) Of a lower coefficient of thermal expansion than typical forged pistons (and, presumably, non-hypereutectic cylinder liners)

Guessing this is why:

a.) Nobody likes them
b.) Gen III engine owners complain of piston slap

???

 

Hypereutectic refers to the family of aluminum alloys used to make the pistons, I believe that they are cast though.

Cylinder liners are almost always iron.

 

Looking good.

A few things i picked up on...10.9:1 compression. That's a bit high. I guess we won't be seeing too many blown c6's, atleast without internal mods or boosting anything above 5psi. Anyone also pick up on the weight? 3245lbs. I'm assuming this is the coupe???? How does this compare to the C5? Since it's physcially smaller than the c5, i would think it would weigh less.

 

Hyperpathetic....errr.....hypereutectic pistons are indeed cast. Most are actually quite well suited to applications that do not typically have to endure very high cylinder pressures - such as what happens when detonation occurs, especially under boost. For a N/A combination, they are typically a great choice, as they have better thermal characteristics than a typical forged piston, better potential oil control (don't expand and contract as much), and are usually cheaper.

The downside is that they are brittle, and this becomes a significant issue when exposed to detonation, especially under high-boost (high cylinder pressure) situations.

I wouldn't be surprised if the LS2 does indeed have these pistons. They make sense in an engine that isn't designed for boost.

I would be surprised if they had cast rods.

 

One other quick thing....looks like the T56 from the Z06 (except slighly different OD gearing) will be offered in the regular Vette. That's a good thing - the 2.97 1st gear will help get the cars moving smartly over the old 2.66.

Neat.

 

It looks like the Z51 package on the new Vette will put the C6 at about the same levels of performanceas the '04 Z06. THe Z51 will have better brakes, Z06 like suspension, Z06 like tranny, and better tires.

THe Z51 C6 looks better than the Z06 C5

"The Z51 Performance Package – the choice for the serious enthusiast – features an asymmetrical-tread tire that offers maximum handling performance. The wheel and tire sizes are the same for the Z51 option, which will deliver handling abilities similar to the 2004 Z06, despite the slightly narrower width of the new tires.
"

"The optional Z51 Performance Package is a competition-ready system for the true performance enthusiast. It offers more aggressive dampers and springs, larger stabilizer bars, Goodyear Supercar tires with an asymmetrical tread pattern, and larger, cross-drilled brake rotors for outstanding handling performance that is still comfortable for daily driving. Beyond the suspension bits, the Z51 is a total system that takes the “regular” C6 to near-exotic levels of performance. It features gear ratios borrowed from the previous Corvette Z06 for maximum acceleration performance, and includes coolers added for the transmission and power steering systems for aggressive, track-oriented use. The result is a car that very nearly equals the Z06 in track performance – representing a tremendous value."

 

As the owner of a new 04 C5 Z06, this hurts--especially if the price is what is now rumored. A few months ago, everyone was talking 52-5 for base C6, 65-70 for Z06; now, they are saying 45-6 for base, so with the Z51 package and a few other goodies, probably 49-50. While there will be no discounts or trick financing on the C6s, at least for a while, at that price, that still is a great deal, even if I did get 7500 off sticker on my C5 Z06. You pays your money and you takes your chances....

 

sounds to me that a big cam will make a pretty big difference. i cant wait till '07. oh and who really needs a 90mm tb?

EDIT: look at the description for the interior, the c6 comes with high performance cup-holders!!!!

 

Honestly I'm kind of disappointed. I mean I'm not knocking GM, since thats all I've ever owned, but where is the power!?! Make something that will compete with the Viper and gawd make something that wont get smoked by a freakin mustang with $1000 in mods.

Having owned a C5, I completely understand that owning a corvette isn't all about how much power you have under the hood. It's about owning the best sports car of all time. Once you drive one, you'll always want one. I'm just saying it would be nice if they would have made it a turbo version of the LS1/LS2 whatever and increased the power to 450hp.

Just my .02 cents

Keep in mind 400 horsepower is A LOT.

As for the competing with Viper... well, Viper costs twice as much as the base price of a Corvette. I don't know that is is totally fair to expect equal or better performance.

However, the 2006 "Z06" is supposed to have 500 horsepower. If it keeps it current price range, which I suspect it will with a slight increase, whoich is normal, then all the stuff I said just goes in the toilet, and I assume it will.

Add to that the swirling "Blue Devil / ZL1" rumors... a production Corvette with around 625 horsepoer for $100,000, and you have something that just will smack down just about any production car ever made.

 

Four hundred underated horsepower in a base engine, seems more than ample to me.

 

400 hp as a base engine, in a car that has a weight of 32xx pounds, has a lot of torque, and we know is underrated and faster than a current ZO6 is pretty damn good. The real question is: how much is it under rated? I say it will dyno 380 to the wheels.

 

It's a pretty bizzare world we live in when a Corvette comes with 400+ horsepower & torque in base form, weighs just a hair over 3000 pounds, is the cheapest 2 seat sports car in the world with more than 4 cylinders (let alone 8!), outruns pretty much everything on 4 wheels that doesn't cost over a quarter mil and people still make posts like this:
The current Z06 AS IS runs with a Viper at over $30,000 less. The C6 has about the same power as the current Z06 and is about half the price of a Viper!

Come on, let's keep a little perspective here!
