Ok! Sounds nice, what did you base your calculations around? Cfd? Fluid vectors? Or was it on a more basic level than that? Hope it works perfect for you!
It is based on a Jenvey system, manifold, inlet trumpets etc. I'm sure these guys have done alot of testing using cfd as they supply most of the touring and rally car teams.
Plenum was calculated using good old pen and paper maths, and is tapered to avoid forcing air into No. 4
Thought about using cfd for it but I'm not after chasing figures and don't know how to use the software yet
Should be good enough for my needs, only looking to run 300bhp.
Are you building a manifold for your engine?
