Gentlemen,

I know that this is an old thread, and a lot of people aren’t tweaking their cars really hard anymore, but I was hoping to get some feedback.

I’m building a 3.7 litre M112 for my SRT-6. I’m trying to achieve 20 psi of boost. I’m using Rob’s 178 mm crankshaft pulley. What size supercharger pulley will I need with this volume and 9:1 compression?

Kindly,
Miguel
