a friend of mine is going to help me make a hoodscoop for my car but there are a few problems. First, how would I make it water-proof. Secondly, If i decide not to do this, what kind of box could i use to get more air in the engine.

Is this for a turbo car?

if it is carb, hook it up to the hot air intake, use flex pipe, and a coffee can, and your imagination

Anyone have pics of a hood scoop (Besides TWE's car) on an EA81?

Yea it is a carb, are you talking about that inlet that comes from the exhaust and goes into the carb on a cold day? If it is then how would i stop that flap from closing when the engine is warm? Secondly could i just put that hose somewhere else. And yes lastly what do you mean with the flex pipe and a cofee can
