i mean theres like what only one pulley smaller then 2.75
i know our heads flow well but i mean with the v2 and 2.95pulley i was seeing close to 550rwhp and 13.5psi on my mustang
i will figure it out i guess

The pulleys that Stillen use on the back of the blower and Jack shaft are big this slows the blower down.This is the reason why people have a problem making torque and Hp with the blower. The Stock pulley that comes with the kit is 3.12 that's not small at all either.
This is the reason why I put cog pulleys when I had the Stillen kit because I knew the blower was spinning slow. It is also the reason I made 465 Whp 360 TQ on a dynojet with the bigger pulley that came with the kit. The only way to get the blower to even try to crank out more psi is to use the cog pulleys that I used. But doing so you have to change a bunch of other things with the kit that have been talked about already.
I hope this helps you understand better.
