custom intake manifold

[mephi]

Could you make an intake manifold out of steel tubing and plating for a carbed car? What would be the issues or problems with such a setup?

rust, and it would have to be trued up or it would leak (flanges)

yea you could do it,the main issue with steel is weight, if you are able to do it,just get them powdercoated and you'll be fine as far as rust, i would reccomend stainless though.

Thanks!

what carbs are you trying to fit?

Hmm never thought about rust inside the manifold. I dunno what powdercoating would do to the fuel flow inside, I would think that the smoother finish of the powdercoating might cause some fuel sticking or condensation.

i meant the outside not sure about the inside

Well considering I have a 90% finished steel intake manifold at home, I'd say I don't really see a huge problem with it. Would the fuel inside protect or cause corrosion?

I was thinking about making a new manifold for my 38, since the stock honda position causes it to stall out on hard turns. I really just want to turn the thing 90 degrees, or if I could find some nice ones, just screw the down draft and go with side draft. It's something for the future...Just a slightly drunk thought when I asked the question. Come to think about it, I do have an older Yamaha in storage right now with 4 side draft carbs on it. I might just take a peak at those if I can't get the bike running soon.

Couldn't you get that crinkle coat powder coat on the inside and then not worry so much about the condensation or rusting?
