I'm looking for a weber intake flange. Where the trumpets would normally sit. I'm making a turbo plenum for my weber's and can't seem to find a flange for it. anyone have any good ideas on where to get one?

I found some on ebay, but I think those are for the lower part of the webers that bolt to the intake manifold.

 

Pierce Manifold has more webber stuff than anyone else I can find, I looked on there website and did not find any flanges, but you did not mention which webber you needed a flange for so that may not mean anything, I would call them and see what they can come up with. In the past they have been able to locate things I needed that they did not have.

 

Rotary Shack??? I know he turbo preps webers and has made them in the past.

 

just get a the gasket that goes between the air horns and carb body. and use it as a pattern.

Easiest way to make a plenum is to use a piece of aluminum boxed tubing.... 4x4" is good. Cut out the pattern on one side usign the gasket and an inlet hole on the opposite side. Then weld the ends shut with a 4x4 square sheet of aluminum on each end.

 

blow-thru???? that depends on which weber and how much boost you want. Personally, I wont use a 48 IDA as I havent seen a plastic seals; otherwise you will have boost leak around the shaft. On the other hand, plastic seals are available for sidedraft or IDF (this is widely used for boost application).

 

Its for a 48dcoe side draft. And i'm still deciding on building it for draw through or blow through. I like the idea of draw hrough and a side draft. With the idea I have for that, it looks awesome in my head. I'm not looking to make crazy power. Just trying to have fun with this one. I always have gotten to serious in all my other projects, so with this one. I'm just going to be creative and have fun with it...
