on a second more serious note, has anyone TURBOcharged one of the 3.2l engines?
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...

There have been several companies and individuals that have tried different turbo setups and even twin charged setups on this car and other amg cars. I think there are several on this forum even. I've never seen one that has been reliable, affordable, and available "off the shelf". Most of these projects are eventually abandoned after a year or more of frustration and a lot of money down the drain.
VRP is currently working on a couple of big projects for individual customers. On one they are adding two turbos to a V12 twin turbo engine, and the other they are twin charging. Both were claimed to put out close to 1000hp. I believe the 1st car is now 6 months past expected completion date, and they haven't even fired the engine yet. IMO these guys are some of the best tuners out there, so it will be interesting to see how these projects come out, but it gives you an idea how hard these projects are. Could you imagine being without your SL65 for 9 months?
LET is working on a twin turbo project for the 32 motor which they started in December of last year. They said in Feb that it would be done in a few weeks, and I still don't think they've had it on a dyno.
