Quad Throttle Body Setup for 951
There's a company in the UK, called 9M, that's producing this intake for the 968.
They are considering making a version for the 951 if they can get enough orders in.
This is a beautiful piece of engineering and will certainly do things for the 951's out there with cams, Garrett style turbos, and big open exhausts.
Obviously the runner lengths would be shorter, and without as much curve, so as to fit a turbo car. Also, there would be no velocity stacks. Instead a plenum would be in their place.

Thoughts?

in the photo the injectors are in the stock location, not sure that the remote mounted injectors in the second picture wouldn't cause gas to pool at lower engine speeds. It sure is pretty though, also looks very expensive.

The second photo is a CAD mockup of what you see installed on the 968.
The injectors are in the stock locations.
The price, according to Collin at 9M, is about $3200 (according to my conversion which could be wrong). The exact price is $1995L (UK Dollars). So convert from there.

I am apologize for my ignorance, but could somebody please explain what exactly velocity stacks do and how they work? I would really appreciate it. TIA!

In laymans terms:
Velocity stacks straighten out the air flow before the air enters where ever it's going. In this case a throttle body.
Also, Velocity stacks increase the velocity of the air entering where ever it's going. Again in this case, the throttle body. They [velocity stacks] do this by starting out large, then tapering down. The taper down, is what increases the velocity. Increased velocity (speed) means more air can enter.
Velocity stacks are only effective on a normally aspirated application where the engine is "sucking" the air.
In a turbo, or any forced induction application, the velocity stacks are useless since the air is being forced in.
This is why the proposed individual throttle body induction pictured above, isn't going to have velocity stacks.... but rather a common plenum, which is what the turbo will feed into.
Hope this simplistic explanation helps.

The setup pictured is for a 968 and will be used for dyno pulls ONLY. The final product will have a plenum, and complete air intake/filtration setup.
Like Tony mentioned, a 951 setup will not require the velocity stacks. It will use a plenum and full induction setup with filter. He's trying to gauge SERIOUS interest in a quad throttle setup like this for the 951 because the 968 manifold is nearing completion.
