Wow, bumped a 4 yr old thread. Nice.whats smallest pulley you can run on a 2.8 non lc kenne bell?
I have a 3” Pulley with a 2lb lower I run. 26 psi of boost.
KB does not rate the blowers on boost, but RPM. I calculated it out and I am 300 rpm under the max with a 3” upper, 2 lb lower and at 6500 rpm.
