I am looking into getting a Pro-charger or a Supercharger and I don't know what one is best,I know getting a supercharger to go under the hood will be hard but it also will be easy to put on.But I want to know what one is better?

 

procharger is a supercharger....

 

is a pro-charger not more like a turbo and does not take place of the intake?

 

technically, a turbocharger is an exhaust driven supercharger...

so this whole thread is about the form factor more than anything..

 

OP wants to know which is better:

A screw or "roots" style blower GMC 6-71 8-71 etc.

or a centrifugal style (Paxton, Novi, Procharger, etc.)

to answer OP's Question, centrifugal blowers are typically more efficient and compact and have potential to build more boost with an intercooler.


That is not to says roots style blowers are no good. These blowers were initially used on diesel trucks where room under the hood is not an issue.

Early Hot Rodders figured out how to modify them to work on gas engines.
Normally boost is kept to 8 psi or less because these blowers typically do not have an intercooler.

That is not to say roots style blowers are not good. There have been many OEM platforms based on them and when engineered properly they can be packaged with an intercooler and kept under the hood.

(Thunderbird SC, C7 Corvette, & F150 Lightning, to name a few)

Superchargers of both types are typically easier to install than turbochargers because there is no "hot side" (exhaust) piping work involved.

The difference between a supercharger and turbocharger is this:

A supercharger uses the engine's crankcase via a belt drive to build boost.

A turbocharger uses the engine's exhaust gas via the exhaust piping to build boost.

same concept but different process.
