That is a velocity stack

whats its purpuse?

Velocity stacks reduce turbulance of the in-coming air.

thos things are sweet!

"I have read a great deal concerning this topic since I posted this awhile ago. Basically a velocity stack forces the air to go from turbulent to laminar as quick as possible. The laminar air entering the turbo inlet would be less likely to heat up as turbulent air. This would net some gain, but nothing really significant. The gains that are seen on N/A engines are due to the vacuum conditions the engines operate at. The velocity stacks increase the airflow from turbulent to laminar flow, and therefore speed up the airflow allowing for more overall flow to be generated. On a compressor inlet of a turbocharger air is already quite laminar so the gain is minimal. If you would add internal velocity stacks inside of an intake manifold, greater flow would be achieved and more power would be made. There arent any aftermarket intake manifolds to my knowledge that have internal velocity stacks for Honda's. Flow would improve around 10-12%."

"Now modifying the compressor housing tolerances to enduce a more laminar flow has a profound effect on efficiency and power..."

wouldnt use it on daily driving cause theres no filter and you dont want any dirt getting sucked into your turbo

Hey, thats our stores supra. Old pic though, **** is looking way better now
