Any generally accepted method to bench test heads for use under boost?
Sorta what I was thinking but seems like there must be more to it.Why does it matter on a supercharged combo anyway ? It's mechanically pushed in and mechanically pushed out. Make it extremely big, don't hit water, put trash can lids in for valves and leave enough material to withstand the heat.
When heads are done for superchargers the exhaust port gets hogged out to evacuate the port quickly. This is gonna head down the pathway and argument of larger exhaust valves vs. the maximum intake valve. Flow percentages or I/E ratios.Sorta what I was thinking but seems like there must be more to it.
Yes I have... I beleive I got it go flow with a 2.08" valve 319-321cfm @.650-.700 lift exhaust was in the 220cfm or so... It's an ok head but for blower the exhaust port in not good... Better with any of the trick flow R or HP....You ever done any port work on Victor jr heads?
