Of course most people get all excited about the so-called "cold air intake" systems out there that really end up sucking hot air from the engine compartment. But, to me, it looks like the real flow "bottleneck" is not the intake but the tube from the intake to the throttle body--especially where the air must take a sharp 90-degree bend at the throttle body.

It seems like there should be some enterprising vendor out there who could produce a tube that smooths out the flow a bit better--no?

Very True, but actually there are even two sharp 90 degree bends after one another, one form the intake tube onto the throttle body, and next from the throttle body again 90 degrees forwards to the supercharger.

I have eliminated both for the twin-screw kit, and obviously that does make a difference, the more power you select (via upper pulley change) the bigger the effect.

The higher the pressure difference (so vacuum in intake elbow before the SC, and outlet pressure) the more power the supercharger consumes from the engine, especially for the Eaton due to its roots design consuming more power from the engine in the first place.

So by reducing the vacuum you have a win win situation, 1) less vacuum equals less engine power needed, so more power to the wheels. And 2) more airflow so more engine power.

You would need to redesign the intake elbow for optimum performance, then the intake tube would fit right on without a bend.

 

Does the twin screw kit turn the throttle body sideways to the right then? That's what I'm picturing in my mind from what you said above.

 

Yes indeed, there is only a large U bend, from the airbox to the supercharger.
