Supercharger or turbocharger

[ls7camaro]

so ls7 is a bad idea? i was going to forge the ls7 how much heavier is the lsx block over the ls7

[ls7camaro]

i really want to get a kenne bell supercharger for it, so would it be possible to put a kenne bell on the lsx?

as long as the boost is kept low, its OK. But I would just build the LSX for the $$.

but could a kenne bell be added?

Yes. The LSX block has the same external dimensions as the others, hence the "LS" designation.

Some additional info for you ls7camaro from a post a while back:

To get an LS3 to support 800 crank hp is pretty cheap, but you have to be willing to yank the engine. Change the pistons to a JE (or comparable) forged in the 8.0 to 8.8 range (your preference) and change the rods to Callies Compstar (or comparable). Put it back together and add the boost of your choice. The crank is cast, but like a Scat 9000 undercut and with fillets. Not forged, but tougher than people think. The LS3 is a 6 bolt aluminum block, with 4 bolts per cylinder clamping so past 800 hp, they may "leak" without O-ringing. In addition, pushing it past this level you may run into problems of spliting the sleeves and the material behind the sleeves. [Note: this is a problem with the LS7 also - 5 brand new blocks split this way]

To go bulletproof, an iron LSX block (6 bolts per cylinder) or if you really need aluminum, the new RHS aluminum block. Add Oliver billet rods, change to a Dragonslayer or better crank and use the same JE pistons. Bottom end now good to well beyond 2,000 hp and this has been verified on the dyno. Took the bottom apart with 90 pulls over 1,500 hp on one of these setups and the bearings showed NO signs of wear. Looked like they were just put in.

The bottom line is what do you really want ? A complete LS7 is a great motor. It is not the cheapest nor the best way to go for a boosted setup.

what about a billet block from dart

more money to be spent.

your best bet is to go with an LSX. doesnt even have to be a 454, you can order whatever size bore you want and match your pistons/crank/rods to it. then throw some LSX heads and a blower and hold on to your nuts

A Single Turbo is the way to go. More power and alot more torque. Superchargers are sweet but it takes power to make power when you run off a belt, but a turbo uses free horsepower. The fastest street cars in the world run turbos, period !!!

But in all seriousness, probably a supercharger, only because turbo's often require an intercooler, and that's just more work to cram it under the hood...

You can add both, but it's pointless. The way it's setup is the the turbo feeds into the supercharger or vice-versa (I don't remember which way it goes). Saw a video of a Mustand that had it done a while back and he was only pushing 400 horses.

I'm not sure which one I want to do... either one of the Edelbrock street legal S/C systems or the STS TT kit.
