I don't know if this was answer already and i know this thread is quite old, but i have a couple of question for Russ or anyone at them team if they can answer them
1) What make you decide going for a sharp 90° end tank inlet/outlet exit in comparison to a Cobb IC that has the inlet/outlet 90° as a bend? any difference in performance?
2) what made you decide to go for a 22inch core instead of the 27/28 inch core of most of the competition? was it because you could make it 3.5inch deep instead of the 3inch deep of most of the competition?
