Cosworth Intake Manifold
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.

I seen some of there cast products at the sema show! I'll be honest it's the best I've seen from anybody!!! I'm talking fit and finish how it performs I don't know but it looks as great...
I want to see the specs on this to see how it compares to Blitz one, which has 2.8L plenum and polished velocity stacks. Props to Cosworth for coming up with their unique design. Pretty sure the bore size on the TB side will be similar to stock, but boring out to 65mm or 75mm should be piece of cake.

Cosworth made the best intake plenum for the VQ motor and received huge praise on it, I'd assume this one is leaps and bounds above the Blitz surge tank. My only concern is compatibility with a 75mm throttle body like Hiboost said...?

On second thought, I see very little difference in design between the Blitz and Cosworth. The only selling points would be 75mm option or at least easily able to get 75mm out of it with still having enough wall thickness, and obviously the price.
I saw the Cosworth one at SEMA... it's really damn pimp.
I only found one picture of the BLITZ after a quick search. It looks like the runners on the BLITZ are fully machined and then attached to the manifold; so there's a lot of the potential cost difference with the Cosworth.
A major design difference that I can see is that the inlet into the plenum of the Blitz is lined up with the runners whereas the Cosworth has the inlet offset down. I THINK the offset will allow the flow to distribute more evenly to all the runners. From what I know, on a basic manifold where the inlet is lined up with the runners, it's possible to starve the first runner of air at high flow levels. But hell, I've been known to be wrong before
And the angle of the inlet relative to the runners plays a big role too I think.
Also, I spoke with one of the Cosworth guys about it and while it's not specifically mentioned, the volume of the plenum is adjustable. If you want more volume, just make a spacer to go between the base and the cover.
