I think it's smooting the air flow to the intake manifold, and maybe giving a venturi effect like on Spoon TB. - but not sure.
Interesting . . .



so it's all down to physics as the equation above demonstrates?

Why doesnt it become V2 = V1 P1 / P2 instead?
I'm not sure, but surely the venturi effect applies to fluid/gas being forced from a pushing flow?

Air is being pulled in through a restriction so is this different?

i looked into these and they only seem to work on older cars, cant seem to find it but i did a google and a few people tested them and got 2bhp gain at most

You wont see 4.5 bhp gain from this at all.

You may see 1-2hp if you portmatched the TB to this, then to the inlet manifold. Its all about smoothing the airflow :)

This *used* to work with old cars.
Old cars with carburetors.

On modern engines it also works by making you, I mean.. your wallet lighter, thus car faster :)

hey people what you think about this mod? Is it okay for the money or not important?
Or will even the TB bypass?

I have a TSX TB with 68mm from airintake and 65mm to intake manifold.
P2R what you would make, with the 70mm?

Yes I know, but it is not better to install the P2R as a barrier to the intake manifold because TB his heat from the coolant passes to intake manifold?
There should be enough to do the TB bypass mod?!

If thats an issue for you why not stop coolant going through the TB?

the heated coolant through the TB, reaching and transfers the heat to the intakt manifold, and thereby the intake air is heated.

What think you about that fact?

exactly, stop the coolant going through the TB then. Unless you have really harsh winters?

What's for you a harsh winter? -20°C
I think too, the TB bypass is the cheapest way over the P2R.
