Could u basically say the ZL1 comes with a Ls9 motor?

The LS7 has titanium rods and valves. I highly doubt the piston selection was based primarily on going cheap.

Price out one ti rod, then tell us that engine was built on a tight budget. I'd wager the parts were selected for being the best suited for the application.

Want to add heavier forged pistons to your LS7.... would you still like to pass all the validation tests.... ok then, lower the rev limit way down... which kills you peak hp.... oops just missed one big criteria for the motor of being 500+ hp naturally aspirated.

If someone thinks they need forged pistons because they are going to boost or spray the engine... then they'll need to build the engine to meet those specs.

They aren't turning high RPM's....6,600 or so isn't high by any means. But, you guys are right, T6 Hyperuetectic aluminum pistons can be made lighter, able to transfer heat better, reduce cylinder wear, and can be fitted to tighter tolerances. But, they are brittle, and detonation and high cylinder pressures are the potential death of them. You can wing forged aluminum slugs easily to high R's as well. New fangled technology. GM knows best!

I can tell you for a fact the blower improvements are the majority of the gain.

Hey Redline,
If you're a member of the cadillac owners forums, can you comment on this topic in the thread I started over there sharing your observations? Some of the V owners have taken an interest! Thanks.

Drake: Heck ya man! It's a Camaro ZL1! It's the first one ever built...Actually it's a pre production test car that GM gave me cause i work as an engineer for them...

Car enthusiast: Oh wow, Awesome man! So is it pretty fast?

Drake: Dude, it's faster than the new Lamborghini Aventador...It will do 0-60 in 2 seconds flat! It will also do the quarter mile in 10 seconds...!

Car enthusiast: Holy crap thats got to be fast! I remember hearing those guy's talking about 10 second cars in the movie Fast and The Furious and those cars were insane! They even had NOS!

Drake: Yeah my car can do that, but without NOS...Even though the engine was built to handle it...

Car enthusiast: NO WAY! What kind of motor does it have? Is it a Big Block? Is it Turbo'd?

Drake: Dude, its the same motor that the 175,000k Corvette ZR1 has...
It's the most powerful motor ever built by a car manufacturer. The block is made out of Titanium...

Car enthusiast: Unbelievable man! So how much does it cost?

Drake: Well you can buy one for 80k right now...

Car enthusiast: Holy cow man! Thats alot!

Drake: Yeah man, the whole car is hand built...

Car enthusiast: Ok well thanks for showing me your car, gotta run...

Drake: Cool man, see ya! (thinks to himself, yeah im the ****)..

Car enthusiast: (who happens to know Drake was full of BS) thinks to himself,

You put alot of thought into this... your idiocracy shines well through your words... im sorry you cant read what was posted before and why this thread was created... id be mad too if i drove "nothing"

i was shocked by the vid as well.. he usually isnt this leanent towards american cars... but this BLEW him away

I think its more to do with the Cavaliers vs Vols. Drake???

But DRAKE -- You can get LS9 engine badges to put on your fenders or hood here!

Isn't idiocracy a country/kingdom ruled by an idiot? HaHa!

The LSA has pistons? I thought they used the new pistonless technology. Less rotating assembly because the Mustang has 650HP.

Correct! You have hit the nail on the head about the much cried over ZL1 technology that has not been disseminated yet...

Are you talking about LS7's? The rev limit is 7000, and they will run there all day long. The LS9 is 6600. Piston speed and inertia at that rpm is huge. Put a heavier piston in there and you'll never pass the validation OE engines require. Sure you could build a race motor with heavier pistons, but show me it surviving the max load dyno cell validation for a couple days straight max load at 7000 rpm. Most builders that boost the LS7 and use a forged piston then lower the rev limiter down to the 6500/6600 range. Same reasons GM limits the LS9 to 6600.

The Z06 has some specific performance objectives; hp/weight, 0-60... and one of the keys to those is that 7000 rpm ability, another is keeping the weight down... no heavy supercharger...

Now this is hilarious!
Unfortunately the mod will void your warrantee!
