3 rotor side port intake manifold extraordinary

I just took a look at Bob Mears web site again.

This is the best side port 3 rotor intake manifold and
intake porting I have ever seen. My guess is an easy 330 HP or a bit more
at 7500 RPM.

I am sure it cost big bucks. Lots of hand labor.
Is that a custom made throttle body Bob?

We have not heard from Bob lately. I hope he is still going
on this airplane.
