Right.  Start with a 640hp supercharged 6.2l V8, and then make it ... Fassssssst

If it was you would have seen a build thread.   just a random car from the internets.

Its that turbo gear driven?

[Pete M]

yes.  it is does appear to be a centrifugal super charger.  

[ftpiercecracker1]

Centrifugal SC are usually driven by the belt arent they? This would be the first I've ever seen or heard of a direct/gear driven SC.

I don't know what all is inside the aluminum, but it looks to be very much inline with the crank, so I'd guess that you're right.  

[JMO413]

That would definitely be a crank driven supercharger.

Lots of ways to skin a cat.  Most superchargers are belt driven to deal with packaging in a production car that only has so much room to work with and a bunch of necessary accessories in the way.

 

When you're building your car specifically for the drag strip with a wide open engine bay, you have more options.  Also, that's one huge supercharger, relatively speaking.  I imagine getting a belt big enough to drive it would be a challenge.  Besides, the lack of front accessories means you don't have all of that stuff in the way.
