There are many mis leading assumptions and products concerned with heat soak.

I remember after I got my larger upgraded Saleen heat exchanger for my Series VI Saleen SC, I ran the car for normal driving on a 90 degree day, and then stopped in a parking lot and did a test with my stock hood down with the car running, and occasionally revving the engine for 25 minute. I then opened the hood fully, with a decent cross wind, and continued to run and rev the engine in the same manner as with the hood down. No temperature change while the car was running what so ever. The temp was better than with the old exchanger for sure, but was not aided by a fully open hood with a cross wind.

The heat exchanger does all the work. Endless aftermarket hood designers claim that venting reduces the intake temps in your car as it is running, which isn't true.

The vents are for when you have stopped, and there is the need to release the built up heat trapped under the hood, which works, and the supercharged car with the vents will cool down faster while parked.

The fact that the newer supercharged cars have the larger heat exchangers over the ones in the 90's and mid 2000's is great. This is what reduces heat soak while pushing the car, not the vents. This can be misleading with supercharging. N/A cars also suffer a good deal of heat soak while running hard. Erik
