I already have Rob’s 178 mm crankshaft pulley installed. I just picked up a UPD clutched 64 mm supercharger pulley. I want to run both in conjunction.

Anyone running this setup, and how has it worked out for you? Do I need to do anything with the supercharger to spin it at higher speeds?

My build is going to be as follows:

Stage III Needswings Heads
SLR Spec Cams
630 cc Injectors
CL 55 AMG Fuel Pump
Needswings DCAI
Needswings Intake Manifolds
Needswings Exhaust Manifolds and Downpipes
High Output Coils
1 Step Colder Ruthenium Plugs
Waldig Super Cooler
Supercharger Cooling Circuit Isolation Kit
Quaife Equipped Differential
Dyno Tune by Eurocharged

Vehicle has 5,100 miles on it. It’s the black coupe that Chris bought from the estate of the Colorado woman who had an accident which paralyzed her. I’ve had it since 2018 now. It’s in pristine condition, and I’m going to build it. I’m dealing with a hip replacement currently, but as soon as I’m driving again the vehicle is going to Needswings for the build. Question, does anyone dyno tune up in the Cleveland/Pittsburgh area who is good with Mercedes-Benz? Oh, and the factory rims are pristine and in storage. These are some flow formed VMR BBS knockoffs. I’m saving up for a set of BBS monoblocks.
