Crank-driven Centrifugal Supercharger?

[Last Ride]

Hey gang--
In another thread about forced induction, someone brought up the idea of using a large centrifugal supercharger driven directly off of the crank. My question is, would this be a wise alternative when going the forced induction route? You wouldn't have to worry about belt slippage. Would you need an intercooler? The person posting said that he would probably go with a large ProCarcher model like an F4. What kind of power would this produce on a 396 fuel injected LT1 built for forced induction? Would such a setup cause abnormal wear on the motor? I welcome any and all thoughts. I will post in the C4 sections as well.

I don't quite understand your "direct driven" concept I'm afraid. If you mean that the crank is mechanically coupled directly to the drive gear on the blower, I don't see how you could accomplish that at all given the water pump, dampener and belt pulley assemblies that are directly in front of the centerline or attached to of the crank.

That would require completely re-engineering the cooling, charging, power steering, AC and dampener setup.

The mondo F4 Procharger should put the engine somewhere north of 1500+HP at around 25-30PSI of boost assuming you could find a crank strong enough not to have the nose snap off of it due to the load from turning the blower.

But you'll never phyically fit it under the hood of a Vette, so this is a fantasy engine setup, fun to dream about but no one we know will ever build it.

To get an idea what extremes it takes just to reach the 1000RWHP mark in a LT1, go to:
