48 IDA's with EFI

Hi Waitey,

I’d like to start with great job!

I want to share my findings with everyone in the V8 Weber world be it IDAs or fuel injection. I’m sure if your into these setups you’ve all encountered the problems I’ve described bellow.

The only problem I have found with these weber intake manifold designs is that because of there lightweight design (great for racing) it is a major contributor to gasket walking into ports and thus creating un desirable turbulence as well as future sealing issues as well as being a major contributor to throttle linkage being thrown out of adjustment. All this is not good for the everyday driving enthusiasts.

This all happens because of the cored out sections that I have highlighted in red and lack of structural casting ribs going in the opposite direction highlighted in yellow thus creating accordion style flexing and twisting every time the engine heat cycles.

Also show is the modifications of filling in the cored out sections and adding structural ribbing to my blue thunder intake that have eliminated intake twisting and I can verify that I have no more gasket walking or linkage adjustment problems.
