Been looking on this thread for quite a while now and decided to join and ask:
I'm tossing up between the 7163 .80 and 7670 .92. Will the 7163 have the potential to flow over 530 whp at 8000+ rpm?
Scott at Insight in Australia has used the .63 single on the 7163 and I've been told its a MAJOR restriction. My main goal is spoolup with the ability to rev over 8000+ rpm.. yes I want my cake and eat it too!
Thanks for anyone's input
