Cosworth Intake Manifold
Someone get this and measure the outside diameter of the neck on this thing! Some dyno numbers with before and after results would rock too, likely even if it allowed porting the opening to 70mm it would probably be enough to allow a Boomba 75mm TB to flow at it's full potential once you account for the shaft & throttle plate through the middle.
We'll see though...
Hmmm that's an interesting alternative to the Blitz one at 60% of the price point. Once intake manifolds get priced in the $800-$1000 I can see them start to become much more popular. The bolt locations on the "lid" of the manifold woudl seem to make the inside surface a bit uneven although that may not make much difference on a boosted car and the runners are where smoothness counts anyways.
I'm not sure what kind of opening there is leading into the manifold, but allowing for a 75mm Throttle Body would make this very popular. It looks like you could weld a larger neck on there pretty easily if you had to though.

This with a Boomba 75mm TB would be a great setup!
This manifold is not going to be released anytime soon. I spoke with Cosworth and the issue is it does not really make any power. It does not lose power, but for $1100+, 10 - 15 HP is just not worth it as far as they are concerned. It is a very nice looking piece though.

Correct me if I'm wrong, but forced induction engines wouldn't benefit much, if at all from this part?
If you're blowing air into your cylinder at a set PSI, having a bigger IMF or TB won't do crap, 26PSI is still 26PSI worth of air, unless your IMF or TB is so small or not smooth that it's preventing you from making 26PSI or making your turbo work measurably harder to create that level of PSI that it's actually creating a parasitic drag on your engine's exhaust stroke. I doubt this part would be any different from the stock setup performance wise.
Some before and after dyno results might be helpful here.
Having a nice smooth large diameter passageway for air to flow would definitely help naturally aspirated engines though.
