That's exactly what mine is making. 677rwhp to be exact. That's why I was curious.

I have a stock block LS7 in my 06Z with a cam, headers, exhaust, high flow cats, Mcleod RXT twin, a D1SC @ 9psi, meth and we put down 770/667 in 102 degree air. Here is a the dyno sheet and a shot of the engine bay.

Those are impressive numbers. You are running stock pistons, rods and crank? Is your meth kit dual nozzle or single?

Funny thing is ... the block and pistons usually are not first to fail. Any pistons failures out there due to boost?
RPM had a thread of them running 11psi on a Procharger with stock LS7 internals well over 75 runs down the 1/4 miles without failure.

Nobody can give a definate answer on what magic number is the max on stock internals under boost.

You never know when and at what limit things are going to break. To prevent it from happening, there are several measures to take. The tune will help you last long time and also how much boost is applied. I have noticed on CF is that most are lasting in the mid 600 range and @ 6-8 psi.
Good luck.
Good luck.

All stock internals, pistons, rods, crank. Cam is not strock of course. I am running dual nozzle meth and it's set up to start spraying as soon as I come into boost. I drive my car VERY hard and have about 5k miles of very hard driving on it. It's not a daily driver though.

I'll take my chances with the short block at 650 rwhp. But I am upgrading the heads and adding dual valve springs, SS exhaust valves, and a trunion upgrade for the rocker arms along with my A&A S/C install. I'll also have money aside for a build motor.

Its food for thought. I *REALLY* want a C6Z for my next car, but I know I can't leave it stock, and I am very worried that it will break twice as fast as my LS2 car did because of the higher compression and thinner cylinder walls... I'm torn beetween an '08C6Z or an '10 Grand Sport. Still have a year to decide though.

The important question would be: How much are these boosted Z06s getting driven, and how often do they get driven at full throttle? Your average C6Z owner is not a race car driver and the few that do race their cars typically don't want a blower. With a leisure cars driven for a couple thousand miles a year on public roads, even if you really didn't care about getting a ticket, it is hard to sustain more than a few seconds of full throttle at a time, much less under high boost conditions; 1st and 2nd gear are probably going to spin, 3rd takes you to 110MPH and 4rth goes to 165, and even if you did a pull from a standing start to 165 that still amounts to about 16 seconds of throttle and most of that won't be making anything near full boost. ... You might have, say, 10 thousand miles of driving on the car but unless it was tracked or run at the texas mile or similar, then during those 10K miles it probably saw about one minute at, say, 5PSI +.

Hey Sam I run my car pretty hard and I do race it even on the track. The car is built to run the Tx Mile and I will see how it does in March. I didn't get in this time. I went into this fully knowing this could blow at anytime but I also wanted to keep it a little safe which is why it's only 9psi. I truly believe it has alot to do with the tune and Taylor @ Dallas Performance is very good. You are correct though these things are ticking time bombs and most that have boosted Z's don't run them anywhere near as hard as I do. But if I don't there's no reason to even run around here in Dallas because there are many very fast cars here.
