Keeping heat/noise down inside cabin?

[Michael Fling]

Micheal,
I have a few question about putting vents in the air supply to the engine. I realize there will be some high pressure in front of the scoop when driving, but once the air is in the line, doesn't it then becomes a low pressure area due to the vacuum being pulled by the engine. Is this a correct assumption?? If it is then how are you going to get the air to flow into the cabin?? The cabin is not a low pressure area. Those round vents would seem to be mounted at right angles to the air flow. If that is so, then you will have a venturi effect and air will be drawn out of the cabin and into the vent. What about sound waves from the intake? Lot of question here that I am not sure what the answers are. Are you planning to bifurcate the air scoop?? To me that is the only way you are going to get air to flow into the cabin from that scoop.

Bill... maybe you are on to something? I could isolate part to the tunnel to go directly to the air vents. I will give that a go.

So here's what I've done so far to combat heat/noise. Let me know if others have feedback.

I made some aluminum .040 plates to go between the inner tub and the shell and coated the bottom side with heat/sound material. I also wrapped the coolant tubes in header wrap as well as the mufflers to try and reduce heat under the rear clam.

I'll add a question... Do you think it's worth it to apply more heat/sound material to the top of those plates?

Update:

Since installing the plates and muffler wrap (not sure if the muffler wrap did squat) but I can hear at conversation levels inside the cab with the doors closed! Best idea ever!
