Ported Throttle Body gains??

[2112]

Does anyone know what kinds of gains in horsepower or seat of the paints increase I would see with a ported TB? I have pretty much a stock setup except for chip and cold air kit. Thanks.

Imo

The hole in the throttle body (turbo side ) should be the exact same size as the hole in the turbo inlet. Also it should line up perfectly.

It all depends. On a stock turbo, probably no gain. On a bigger turbo, definately a gain.

Can you feel in the seats? Depends on how good your seat is.

On a stock turbo, you probably want a smaller TB to match the turbo inlet, or, enlarge the turbo inlet to reduce turbulance and pressure drop where the parts meet.

Carefully read Lee's post. Not too many have ever done what he has.
