grruminator78: Yup - those are the valve covers. I wans't sure about them until they were in place. With the right combination of polished aluminum, they are jaw-dropping. Aggressive without being a "boy-racer".

I'll try and take a better photo for color...

 

ohhh man I love em, that's what I'm doing, plus they clear roller rockers.

 

Okay so its basically using a turbocharger run by a belt to force air in like a supercharger. So this setup is kind of on the grey area between turbocharger and supercharger as it borrows ideas from both concepts.

Cool

no i think this is just pretty much a super charger and the two things are somewhat similar. A turbine driven super charger is a "turbo". A belt driven turbo is a "supercharger". Its the same concept pretty much.....just differnt ways of doing it.....both of them basically just compress air and force it into the engine more than the engine can do on its own.

 

Okay got it!

Do they use gear driven superchargers anymore?

Her's how it works (taken from the Paxton web site):

A supercharger is an air compression device that forces air into an engine. The device allows more air and fuel to be forced into an engine than is possible under normal atmospheric conditions. The mixture of compressed air and fuel in the engine produces a higher compression ratio resulting in more horsepower and torque. A supercharger also allows a vehicle with a smaller displacement engine the ability to perform as a large displacement engine.

 

I found this which better answers your question:

What is the difference between a Paxton Supercharger and a Turbocharger?
A: Turbochargers are powered by exhaust pressure while superchargers are driven from the engine crank pulley. Superchargers allow you to attain boost and horsepower on demand. A turbocharger requires the exhaust pressure to build resulting in a "lag" in horsepower increase. A turbocharger will typically have a higher discharge temperature than a centrifugal supercharger. This higher temperature is a result of the turbo impeller spinning faster and the heat generated from the exhaust gas.

 

yeah to my surprise turbo's impellers spin up to around 140,000 RPMS

thats just insane

 

Thats exactly right. Turbo runs off exhaust pressure, super charger runs off the engine mechanicaly. Could be gear or belt driven. Turbo commonly offers lag, but a super charger will eat more power off the top end. Give and take.

 

i have seen twin turbos, i dual blowers...... has anyone ever built a turbocharged, supercharged setup? could be one crazy *** setup
