Hi guys,
I'm designing my car team's air intake and I have been struggling to find solid information, including reliable calculations with variables explained, for both runner length as well as plenum volume and design. We are working with a Honda TRX 450 cc single cylinder engine and most plenum designs are based on four cylinder engines. Does anybody have any helpful resource (website, book, etc) that has detailed information on plenum volume and design (with calculations) as well as runner length calculations?
Also, if anyone knows, if the runner length includes a bend, should the length be modified to account for this?
Thanks!
