the pulley is both internally dampened and neutral balanced prior to attaching to the crank shaft...
the 185mm pulley (the biggest we offer) spins the blower at 19,250rpms, very safe buffer zone from the max rpm of the blower...
please let me know if you have any other questions...thanks!
Can I run the 185mm safely on 91 octane? That's the best I can get in Vegas. Otherwise I'd have to mix with racing fuel like I did with my Lotus (a real PITA)
