Who sells Procharger pullies, and are all 6 ribs i

Nobody, including ATI, seems to list these on their site, although many other blower manufacturers do. Does the version of the P1SC matter? Anyone?

AFAIK the pulleys are the same for the P1 and D1 blowers... I won't link them because they aren't a sponsor, but no sponsor that I know of sells them, so I think this is ok.. Just look up Exotic Performance Plus and ask for Bob.

Actually I am just looking for a site that lists the pullies for sale right now. For some reason Vortech does, but ATI doesn't.
I see EPP has a detailed belt application table which helps. I have tuning issues to deal with before I mess with the boost. I am learning why people become married to a good tuner with FI. Thanks for the response!

What size pulley are you looking for? I have a couple laying around. Used of course.

I am at a 3.85 and 7psi now. I am thinking I will need a 3.7 and a 3.6. I will likely be adding headers but also want to bump the boost to 8psi once I get the tuning sorted out. And I may add a restrictor plate which will cost more boost, depending on how much bottom end power I can tune back into it.

Sorry, smallest one is a 4.0 I'm using a 3.85 now too

Restrictor plate?

It goes between the filter and the inlet duct. Reduces airflow to reduce peak boost to whatever you need it to be, but then allowing you to run a larger pulley to increase boost lower in the power band. I want maybe 8psi but with the right restrictor and a 10psi pulley it will pull like a beast on the way there.
I have some tuning to do first though. I may not need it.

Hmm, any pics?
