In another thread some of us discussed a variety of methods to get fresh, cool air to the engine to assist in engine cooling.

I ran this setup at M-O last weekend and my CHTs dropped to under 400 degrees for the first time since my engine rebuild. Before these ducts, I could only run 1 or 2 hot laps before my CHTs got too hot. Now, I can run 20 laps at M-O and the temps stay under 400 degrees.

2-3" ducts from each turn signal opening.
