What size supercharger pulley?

**Jonathan0498** · 03-21-2018

Hello. I was wondering what size pulley. I could use on my supercharged build. I have a l36 block, cnc cylinder heads, xp cam, gen v supercharger, 5% over drive balancer, and a full size inter-cooler. It is going in a fiero that weighs approximately 2800 lb made it to a 5 speed. all the supporting mods like headers, thermostat and spark plugs.

3.2 or maybe even a 3.0. you'll need a tuner in hand really. that way you can adjust timing as needed.

I’d start with the 3.2” myself. See how that goes.

I always start very conservative...so I'd go to a 3.4 and see where the boost level and max timing lies. My L36 top swapped liked 16* but all builds are different.
