Triple Webers and brake booster fit?

[frogish]

A tuner company back in the day (Viktor Gunther-still exists) that made intake manifolds for the M30 that cleared the thermostat housing and angled up to clear the booster. Quite rare. I have a one piece one, they also made 3 piece ones that look like yours, if you post a close up pic of yours from the top I might be able to tell for sure.

Mine is a Mangoletsi manifold.

Stock brake booster will almost collide with the center carb.
I changed it to a 2002 booster (not Tii) and I am now able to run ca 30 mm long stacks and angled stacks would be no problem.
This is what it looked like the first time I put the carbs in with stock brake booster.

remember, that is a 2800cs booster which is much smaller than the 3.0cs booster

Hi Mark
That is an original Alpina setup?
do you have an end view?

Length of booster I don't think is an issue, it is in there now

I keep every airbox pic I find. I’m at work though. These are from an archived eBay ad. It is safe to presume that these parts are original.

I got my Webers to fit with 3.0 brake booster - they are on Redline manifolds. Just can't get any trumpets on it. I have since sourced a tii booster AND a one piece VGS manifold. I will one day explore combinations towards a final solution.

Thanks Mark! the ones I have look very similar to that, same dimension
I would realy like to use the ones I have alread, there is a lot of work that has done into them

Yes they seem the same, Mine were copied from original Alpina supplied ones

Just fyi -- this is probably not relevant to Mark's original issue, but Ray Korman makes a tstat housing that has a kink in it that provides slightly more room for the installation of Webers. I am using one of Ray's tstat housings and a Korman intake manifold.
