I created a reverse cowl induction air chamber in my hood to draw air from the air dam coming over the radiator support. After testing with temperature sensors in the engine bay and air chamber, there was a huge drop in temperature going into the engine compared to just an under hood 14" air cleaner that I was using before. Also, when I get on the throttle, the engine bay temperature rises, while the air intake temperature lowers during acceleration. Here's a picture of my work, and a video of my testing.

what was ambient temp that day? looks like it works pretty well..
Outside temperature was 55 to 60 degrees during testing. I checked the gauges before I installed them and they both matched ambient temperature. I can feel an improvement in how it runs and performs. I'll take another video when the weather gets hotter.

I ll bet you can...for every 10* below 80* , you lower the temp of incoming air to engine , you gain about 1-2% hp....whats the power level of your engine? Vettex2 is right, sounds healthy

Looks like you have a sweet setup also. Thanks, good to know yours dynoed so good. Yeah, I figured around 500 was a good guess. How about the looks when you're sitting at a traffic light? For the rest of the drivetrain I have a T56 with a Fidanza aluminum flywheel, Centerforce DF clutch, and 370 rear. I knocked some weight off too, with it at 3,180 no spare, no one inside, and 1/2 tank of gas. Aluminum heads would be nice. :thumbsup:

Here's what the cold air modification cost me.

Fiberglass panel was free. My work was throwing it away. (An unused wind deflector for a semi truck roof).

Nortons Speedgrip panel adhesive was $35. I already had the applicator gun.

I already had the K&N air cleaner. I used a 16" 16 gauge aluminum cake pan cut and sealed with rivets to the drop base, cost was $20.

Moroso Cowl Induction foam hood seal cost $20.

I think I paid about $20 for a roll of the thermal insulation.

So, my total cost was under $100.

Also, I paid about $10 a piece for the 2 temperature displays with sensors.
