I believe they still contain hyperutectic pistons so with that kind of shot a good tune would be necessary.
I can't see the video, but supposedly it's of a LS7 spraying a 100 shot racing and the car owner claims something may have happened to the engine after the race.

Yep, they are hypereutectics. Nope, I wouldn't want to throw nitrous at it. The engine was built to rev and to that end I believe a little more camshaft and better breathing would be the right direction to go.

Then again, I'm not much on nitrousing a daily driver.

that's just utterly amazing that the ss beat the z06 with a 100 shot. It said 505hp on the badge on the z06... Is that correct? Those come with 500rwhp from the factory?? That means he was close to 600rwhp and got beat??? Holy cow!

I dont think my fully modded camaro with a 100 shot could take that z06.

 

i thought it was 505 at the crank?

 

It is. OEM horsepower and torque are rated at the flywheel (crank).

 

All of the later info I've read says forged pistons. All of the early stuff I've read said cast pistons (which obviously isn't the case). I've never read anything about them having Hyperpathetic pistons.

 

Actually I believe they are eutectic pistons which means there is as much silicon as can be naturally disolved in the aluminum without elevating temperature as done in hyper-eutectic variety. In either case the pistons are cast.

 

Ahh... Flywheel Hp, Nevermind. Mine would defiantly whoop some *** on a 100 shot.

 

heh,
I've heard so much that HU pistons are actually stronger than forged- except that they are far, far, far more brittle. Never conducted my own test.

Their primary advantages are:
Cost
Weight
Much lower thermal expansion rate


People tend to think that "its not forged, it cant make a lot of power"

proppely tuned- I think that thing could hold another 200hp no problem. But it would need a very conservative tune. The first sign of detonation would be disaster.

On a side note: anyone else notice how standard it is for the gen III engines to knock (not slap) once or twice on startup. Cold start emissions?

 

Yep, they are less tolerant of detonation but also keep this in mind..... "I think that thing could hold another 200hp no problem"......

GM's ring end gaps are probably going to cost you an engine before you ever get there.

You buy one and try it out, then let me know how it goes.

I would, but I dont like the wheels. I guess i'll just stick with what i got till i'm outa grad school.

 

Anyone who buys an '06 Z06 has sawdust for brains.

Not only has GM had a few problems in the past with high performance engines in their first year of production ('01 LS6 oil consumption, for example), but they also tend to follow with a more powerful version a year or so later, like they did with the ZR1 (375 to 400 horsepower) and C5 Z06 (385 to 405 horsepower).

Buy now and you're likely paying a hefty premium to be out-classed when they release the next iteration of the platform in a year or two. Of course, that could be said for those who bought the 400 horsepower ZR1s and 405 horsepower Z06s as well.

 

I can't despute the past, but you're forgetting that most of the guys/and gals (last corporation I worked for had a women as the CFO and another as President!) that can afford a C6 Z06 can probably afford trade in their Z06 on a Wednesday and pick up their new and improved Z06 on Friday. $65k base price for a Z06? I think that is 2x the price of my parents first home back in 1971 . Jokes aside, GM isn't marketing to the 20-somethings with the C6 Z06.

This is just speculation. I'm sure there are some people who spend every penny they have to afford such a car. Those are the people that are going to be hurt (emotionally) by improvements made on the newer cars. That in mind, I feel sorry for anyone who's trying to "keep up with the Jones'".

Btw...more pics and updates, Mr Jim...pliz .
