I would suggest talking with your tuner about that kind of set up. Eurocharged will give you good input.

Research threads on each type of pulley (SC & Crank) and you may find some answers there.

Most are not going that deep with pulley choices. There are supercharger inefficiencies and heat issues that will need to be addressed as well.

I talked to solo motorsports in atlanta ga they recomended me 77sc pulley as its is now and go with a 180m crank

Also i talk to craig hawkens buckhead-imports in atlanta, amazing guy craig by the way, he recommended me to 72mm fixed pulley, 82mm tb, belt wrap kit and to leave the crank pulley alone, with a good tune that I should see some power

It appears you live in the Atlanta area. If I did, i would work with Craig and Buckhead motors exclusively. You might think about what your ultimate goals are for the car regarding mods. Increased boost via bigger counter or smaller SC pulley, cooling and a tune could be all you want. If you have plans for more mods after that, you might discuss it with Craig up front.

If I had a stock SL55 right now, the first thing I would do is install long tube headers and a tune. Of course this can create smog issues in some states. I think LTs create the perfect foundation for future mods or no more mods.
