If so, how did it work out? did they use small or large turbos? here is what I am thinking here... this comes from my aviation background... you can possibly use what is called "Compound Supercharging" where you compress air, then run the charge through an intercooler, then into another compressor, and into the engine... it looks like the crossfire uses a roots into an intercooler, and then into the engine that is standard
supercharging...
compound supercharging will be kinda costly in setup, but the results should be OMG!!! Use a fairly large turbo, no need to use a small one, (because you are already using a supercharger for low rpms) feed an intercooler to get rid of the heat of compression, then on to the main supercharger, and on to the other intercooler (which might be better as an air to liquid intercooler) to get rid of more heat of compression... then into the engine...
this is a system that was used way back in WWII so that bombers could keep the radials running tip top at 30K feet and I have yet to see it in use on the ground...

The supercharger in the SRT6 (and Mercedes SLK32/C32) is a Lysholm twin-screw type made by IHI, not a Roots type. A Lysholm supercharger internally compresses as it pumps unlike Roots supercharger, making it considerably more efficient. The tolerances required make the twin-screw supercharger much more expensive to produce, though.

This phot will give you a good look at the rotors, one of which is Teflon coated.
