What size pulley?

[TireSmokinLS1]

should the D1SC 8psi kit come with?

mine is like 4.5in. I thought most people were using 3.2 to get 8lbs (with headers).

Mine came with a 4.05, but I swapped it for a 3.6 before installation. Made 8 lbs with the 3.6 with LT headers.

Now with a 3.4, I'm making about 9.5 lbs.

p1sc with 3.2 will make 8 lbs, d1sc is a little different, a 3.2 will get you more like 12-13 lbs :)

hmm, i figure i'll prolly see around 7 with this pulley. I can always swap it out though :D

With headers, I'm thinking 4 - 5 at best. I saw about 8 with a 3.6 inch pulley (w/LT Headers).

I saw 10lbs with a 3.4 pulley on a D-1 and stock LS1. Now I see 5lbs, with a 3.4 pulley on a D-1 with Ported and polished heads.


So the more flow u have the more effic.the blower is.
