key word there is most. But I'm not looking at max power or max potential. I'm looking at longevity. and on top of that from what I read about the lsa it's at or very close to the max efficiency out of the supercharger. put a bigger one on there the engine life is cut in half and now what? got a big paper weight like i do in my back yard.

whose to say the new Z28 wont just be a handeling package or some nifty stickers on a body kit? Just a thought, maybe jsut another 6.2L or perhaps a nice middle model with the 5.3L from the trucks. They put them in the Monte Carlo SS and they ran like champs, 5.3 seconds 0-60. Not to shabby.

Don't worry you"ll get longevity out of the motor the way it is. I have yet to see the TVS superchargers pushed to their limit so I doubt that that thing is at its limit. I could be wrong, but you have to look at IAT's, CFM, supercharger speed to determine is your pushing it to it limits. And if your into modding motors putting a TVS 2300 on any motor should require forging the pistion and connection rods.

I dont' know about the efficiency of the LSA packaged TVS1900, but I know Magnuon had told a magazine, in a test on the first TVS'd G8 GT (it was either SC, CHP, or PHR I think) that the TVS1900 would support up to 800 horsepower (flywheel, presumably). That's a totally different SC assembly, but the rotors are the same, but it just seems if Magnuson can get 800 out of those sized rotors, GM's set-up should be within a some-what similar range I'd think, anyways. I need to do some research and see if there are any OEM to Magnuson SC swaps for those LSAs - that'd be a cool test I think up'ing the boost a few pounds wouldn't really impact the longevity of the engine though - it's still got a steel crank, and what seem like good rods and pistons. It does have those piston squirters too, to control those piston crown temps', and if GM brags about it around the 'Ring, then they shouldn't have a problem with people racing these things and deny warranties (what I'm saying is it looks like it's built pretty good; not as over-built as an LS9, but still really well...)

Well, the quote from Mr. Welburn says it - not to sound like a smart@$$... Also, that 5.3 is like down 120+ horse shy of the LS3... To me - that doesn't make a whole lotta' sense unless they drop like 500 pounds...

Putting a 2300 with 6 psi on a stock LS3 SS still sounds like a great option, for me anyways. I keep going back to that because I think that with that mod', a few other basic bolt-ons, and a full Pedders suspension would be perfect for me (with a little pulley action ) and probably come out cheaper than a Z28 from GM. I don't know though, because I'd still be more comfortable in a car GM set-up and just pulley-up and bolt-on a few goodies and be done.

Ugh... You gotta' pay to play

LSA just because the powertrain is in the GM parts bin. Now, if they so chose to do a limited run forged ver. possibly a ZL-1 w/ factory forged internals package that could raise the bar so to speak. (The ZR-1 of the Camaro world)

Non Forged LSA: Base Z/28
Forged LSA: ZL-1

Problem is it such a package would shove it into Z06 territory.. :/

I did not know that they CTS-V engine was not forged. Why would they put an engine in the Z-28 that was not forged, makes no sense to me. It's still going to be just as much as a GT500 but with no forgd internals, come on GM. With a forged engine it just opens the door for almost any mod.

There isn't even a quoted price yet. Try not to jump the gun.

Well, the crank is, but it doesn't share the same pistons, rods, bearing caps, and few other exotic bits. All in the name to keep things somewhat affordable I wished they had forged steel rods and aluminum pistons, but I guess they weren't in the works. I can see why no Ti rods and forged caps, but the pistons; I didn't get that one. I know the LS9 revs' higher, which is why they used Ti rods, and maybe even why the forged caps, but I am only guessing.

Too bad though. Still, if it's good enough to go around the 'Ring, it's good enough for me and my current plans You're right though - it probably doesn't have the potential the 500 has :( Who wants like 700 RWHP anyways

Well how much can you really see Chevy dumping into their Camaro project? And why would they want a Camaro that only the weathy would drive? It doesnt sound like a Camaro? The laws for cars are only going to get stricker in the next few years and GMs spending cant get to much higher just over one car-theyve already slimmed down. I think a lot of people are getting their hopes up too soon-but I could be wrong.

COPOs weren't cheap. Then, you had the ZL1, which costed more than the car itself, if I'm not mistaken, so yeah, I think there's a SLIM chance GM would cater to the more affluent. Do I think this will happen? Probably not. Do I think they should? Certainly not. Why? Because I think GM should directly address the competition, which are going to be Mustang and Challenger models, IMHO. I just don't see a significant change in car-demographics, where you have prior tuner people who are going to come from 350/370Z or even the new Genesis people considering Camaro. I do think GM will get new buyers they didn't have with prior generations, just because this is such a more friendly car.

I don't personally think Camaro shouldn't be for the masses. That's how it started, and I think they should stick to it. I do think there's a market for those who would be willing to spend more on a higher performing car and that they would sell at least a competitive amount to GT500 numbers.

I do hope a lot of us aren't getting all worked up over nothing though...

Direct Injection. High pressure fuel injectors are placed in the combustion chambers, as opposed to the intake runners in the intake manifold, and the fuel is atomized a lot finer so it burns more completely, increasing efficiency and lowering emissions. I think the LLT runs something like 2000-plus psi in the fuel rails, opposed to many MPFI engines, like the LS3/L99, where they run somewhere from 40-50-os-so psi.

I see what youre saying and I would agree. My only concern is with Ligenfelter/Hen and everyone else taking the SS and modifying in such ways, and the 'hero' Z28 to be in perhaps small numbers, would GM take the risk of competing against itself through aftermarket crowd just for same end results as Hen? Although the Z28 is more 'catered' with warrenty and the 'this is how i want it get it to me' ordership, which already has proven strong-but most of us already bought one and cant afford a trade so soon, or another one in the driveway. what if the, dare say, the new Z28, has a MyStErY motor?? ooooooo. Perhaps they want to take on the Taurus with a twin turbo V6? Food for thought?

I think you're totally right on that. I'll tell you, though, that for me, I'd take a 450 RWHP OEM Z28 from GM (and add a pulley and some bolt-ons) opposed to a 500 RWHP tuner-SS because I know Z28 has a powerplant that's been through Hell and back. You're right, though, IMHO, because I don't know how many others would feel the same. Great point.

As long as the MyStErY motor has 8-cylinders, I won't complain, lol Okay, I won't complain as long as it has the performance. I need a big V8 though
