Just a friendly warning dude.

I did a little R&D on this venturi set-up when it was suggested a while back by a not much unliked friend.

It makes you set-up prowen to surging or boost spiking as the velocity of air increases. You will normally see bigger turbo’s have like little holes cut the housing this is to cause turbulence and control the surge.

I will get a picture garret uses another system to help control this, normally smaller turbo’s don’t do this but with a venture it is possible
