Chevrolet Corvette C5-R

Yeah, it was painful.

I mean, it was certainly, well, so the genesis of that manifold actually goes back to my days at KTEC because I drew inspiration from the C5R manifold.

The C5R race program was an individual butterfly, cross ram, massive, long runners, awesome for torque.

And I always loved ITVs, but the problem with an ITV, especially back then, less so today, but back then, was manufacturing tolerances and the controls.

It was really hard to get right.

Now you're talking about two four cylinders, right?

Well, you're right.

We've got two on-fire inline fours, right? We separate the plenums, and the C5R had a communication tube between the two plenums.
