20psi+ on D1sc pulley question

[G.AlMuhairi]

Hey guys,

I'm starting to order parts for my build,I'm going to go for 20+ psi on my D1 procharger the only problem is I googled all day long and I found nothing. I need to know which pulley I need to go for to get 20+ psi and where to buy it. Can't wait to finish the build aiming 700+rwhp

Note: used search option , I couldn't find anything

i had a 3.1 pulley on my p1sc it would make 18psi at 6k rpms. so i think a 3.4 at 6500 would get u there or more.

PM Marc s He has a D1 at 23psi and has been through a few different pulley combos.

I made 14 psi with my P1 with a 3.40 pulley. I upgraded to a D1 and have the same pulley on it. Im getting tuned this weekend so I'll post how much boost it made with the 3.4

I'll PM Marc s now as I have to order the parts this week. cant wait to be done with the build !

You can also call procharger. They can usually tell you what you need. I know we called 3 times on a buddies mach 1 build.

A lot will depend on the rest of your combo. I had a 3.1 pulley and only had 16 lbs of boost. That was with 9.1:1 CR, Livernois stage 3 heads and long tubes. Shortly I will what difference a 9.8:1 CR will make.

 

[Marc s]

On my new engine combo, a 3.85" pulley makes 18.5lbs, 3.55"=20.5lbs, and a 3.4"=21lbs.

I assume this is an 8-rib kit?
