I've seen something along these lines, for a twin choke....it was as you'd imagine it: two swept pipes running to the stock cast manifolds , with some bracing between the two... I'll try to find a pic There was a US company in the 60's/ 70'swho made manifolds to fit to twin progressives....I'd've thought these would've been pretty tasty, if they'd been properly developed...maybe didn't catch on
Not at the moment as i have no bus or engine here I may not go down that road soon but its very much on my to look into list There must be loads of advantage to made from a t junction pipe design?
I think it'd take days on a flow bench and then however long asssessing the temperature effects, stasis etc...mind you, with CAD and 3D printing, it'd be a damned sight easier to mock up....ultimately though, I think FI and engine management are as good as it's going to get, unless you were doing it for the challenge....would be an interesting project
Having spent ages making my manifolds ,this is all yours .you can get real nice dairy bends and Y pieces ... 3D printing has too much creep to catch on ...it gonna be all about the laser
