Anyone using the HH impellers in a blown application like it better than a standard A/T impeller and if so, why?
Sent you a PM
I ran one with nitrous for years, I like them but I also like the regular AMT stuff too, kinda depends on application I guess. Im currently running a Legend and I like it too, probably switch back to AMT this year for a different cut size.
Blown 509 BBC in a TX 19. just basically trying to see if the HH is worth the extra money over a standard deal. 10 psi boost and wanting around 5800 rpm range.
