2007 Shelby - Would you spend the $ for new lighter crankshaft pulley 10-15% over size for increase in boost or have Eaton ported for about same money. Pros/Cons???
Or if you changed to oversized pulley for 4psi and ported blower for an addition 4psi would it be as simple as 8psi or is there some trickery in there? If you added a 2.6 pulley would you have an increase of 11-12psi and blow the thing up or what? How does all that work?
