=============================================

Does this mean with this brand new high performance engine, I could safely swap out the 3 pulleys on the belt for different sizes causing it to spin faster safely?

Or would this still not be a good idea until I get the 928 impeller upgrade?

Any advice / thoughts / opinions / facts are appreciated.

Thank you guys!!
