porting injector housings to 36MM - ZR-1 Net Registry Forums

tpepmeie · 03-15-2021

You are tirelessly focusing on size with the assumption that mm=hp. The critical issue in the inlet tract is getting the air to turn (with minimum pressure drop) at the junction between the head port and housing port. Yes, you can use sheer size to overcome that drop, but doesn?t mean the whole port has to be uniformly large. The factory as-cast injector bosses are the other obstacle.

Marc does great work. And he has refined it over the years. There are others too, but don?t get hung up on size...

Maybe tell us more about your build and goals for it?
