Supercharger

Do we even have a real option for a supercharger. I heard a rumor that our friends across the pond had one.

Steinmetz had a kit out there, but it was only good for about 280hp, after a bottom end rebuild...

Also I heard of a sweedish company that produced a low PSI Turbo kit... much like the Saab 3.0T version, with a single turbo, remotely mounted and it was good for about extra 50hp... on stock motor...

I've found a bunch of universal superchargers that say to engage you have to flip a switch. I want something that is automatic.

The interesting thing about supercharging one of the Catera's is that with access to some machine shop tools it would not be hard. First lets put aside that the drive line will not really be able to handle to much of an increase.

But theoretically, the way the intake manifold and velocity stack system is set on on the car/engine, and because of the depth/length of the Velocity Stacks you could machine an adapter plate that would be mated to a milled to lower its height velocity stack and replace the upper plenum with the roots type supercharger.

You would most like need to make a custom intake to the supercharger that the OEM intake would attach to, but I have seen similar setups on cars before, where there is an aluminum tube that goes to the rear of the supercharge (as the belt attachment is on the front & mates in with one of the factory belts).

Now please understand that I have no interest in doing this, as the cost to performance gain ratio is complete outta wack, but I do believe it could be done. You would change boost amount by changing the pulley size on the compressor/supercharger.
