Max safe RPM for Stillen SC?

MoulaZ

Hey guys, sorry if this has already been covered, but I've spent the last hour seraching and couldn't really find an answer. Just about to put the finishing touches on my Stillen SC install and it sort of struck me what would be a safe RPM to be shifting at? I'd like to be shifting at 7500, would that be too high?

I'm running:
- 9lb Pulley
- 600cc Injectors
- Aeromotive 340LPH Fuel Pump
- Frozen Boost Heat Exchanger
- Stock Headers/Cats
- Motordyne Catback

Also, was curiuous about the ratios and I noticed that turning by hand, the compressor wheel makes roughly 4 turns to 1 engine turn, would it be correct to say the compressor is spinning at 30000 RPM when engine is at 7500 RPM, or am I missing something?

Reason I ask is I like to know the limits of my hardware, and unless I'm mistaken on this as well, Vortech list their V3 SCi with a max RPM of 53000 RPM, which in theory would mean unless we're pushing over 13K engine RPM, we're well within the safe Compressor RPM range, yes?

Sorry, first time running a Supercharger, been Turbo all the way till now. Appreciate any pointers.

Cheers,

Here is what it will be spinning at if your 9psi pulley is 2.75". We have spun it at more than this and havent seen many issues.
