How much boost would a 3.5 pulley on a P1 in a 5.3 motor make?
I have a 4.0 pulley (8lbs boost) on it now but have the 3.5 waiting for the 370 when it goes in to make 10lbs boost. Thinking of putting the smaller pulley on the 5.3 to see what it would do but don't want to make too much boost.. would it go to 12lb ? I am running meth.

What rpm are you shifting at?

the 4.0 made 6-8 on mine until I went catless & a larger FMIC...from then on I made 10+...
I have a 3.4 going on my new forged motor...hoping to be @ or above the 10+ my stock motor made...
I have a Reichard 3.9" I'm going to sell if you're interested...

I'm interested in the RR 3.9 inch pulley


Back on topic.....I think it will make between 11-13 psi depending on how high you spin the engine.

I run a 4.25 on my D1SC and shift at 5900 and it makes 10#'s[6.0 with cam]
but when I ran the 4.25 on my stock 5.3 it made 12#'s at 5800.I also have the 3 core FMIC.

Im thinking 3.5" +12 easy.

Back off the topic 3.85 here will trade for 4.25 or 4.00
