Procharger D1 pulley drop

Has anyone with the stage 2 d1 procharger tried running the 4.6xx pulley.If so what was the boost and was your fuel system close to being maxed out?Any info would be greatly appreciated.

I am only running the 4.75 pulley I was told by ProCharger tech support not to go smaller on the stock engine. According to the dyno I am at 720hp which puts me at close to 830 crank hp. My stock motor is being pushed pretty hard at this power level.

Yea im on the 4.75 too and ran 726 on the dyno.Also guys i wanted to mention question is for guys that are not running a wastegate,as that is a different setup.Hey JadeGt have u ever checked to see what your boost is at?

I was 14 psi on the dyno but we are 50 feet above sea level here and Houston and our fuel quality is pretty good here. Both of those factor in as well.

Wow yea i have to put a boost guage on mine again to just verify,when i checked it when the kit first went on i was at 10 maybe 11 at 7k rpm.U dont want to go over 14 with the stock block,but thats just my opinion!!.

The dyno my car was done on was the Mustang dyno aka the heartbreaker. Once I get a new clutch I will put it on the Dynojet to see what she will do. ;)

What RPM did it make 14psi at?
