is there a problem with running a standard carb with a manifold that has a 90 deg angle in it? aka could i skip side-draft carbs and build a manifold...tia guys

JAFO

you looking to run one down draft?

a_o_smith

out 4a-ge had horizontal throttle bodies and was efi, but for our purposes a carb is better...since i do have a maching shop i was thinking we could buy one down draft (650cfm should be plenty) and then build intake manifolds with a 90 deg angle in them...

JAFO

650 might be a little large. if you have the room i see no problems. what peak hp rpm are you looking at.

1.6l prob looking for around 7/8k and about 180hp...running nitrous too

JAFO

i still think a 650 is large. you may find a 350x2brl a better size, but your dealer will zero you in on size. i'd keep the bottom of the plenum chamber above the intake ports.

sounds good thanks for the advice

its a nice gradual bend, should be fine. if you look at the bottom of say a V8 manifold, there is a checker pattern or lines cast in, to keep the fule atomized and not puddle up at low RPM, soundslike youll be at higher RPM most of the time so shoudlnt be much of a problem.
what kind of engine/ car?
