- Even 5 years after the introduction of the first ball bearing turbo keychain, it continues to be a solid performer that features realistic spooling sound and robust construction. For this year a new upgraded 8 blade HF (Hi-Flo) impeller option is available, the same impeller found on the big brother GE-S2 model. Did we mention it’s 37 trim? Who does that? The HF impeller flows more air over the standard impeller, but with crazy insta-spool.
