[DeTomaso] Engine Bay Air Flow

[hoppe1 at cox.net]

You are correct.   Inlet temp is more important than ram air.
A lot of people argue that installing the air ducts in the side windows is not a good improvement because it is not in the wind pressure.
I have them with EFI and it really helped the car run better especially at idle when the temp in Phx AZ gets over 100 outside and I think inside was more than 185D .

> Yesterday, I taped some light string to my rear deck lid and went for a ride. I was told by a few people (including Wilkinson) that the air flow, at higher speeds, flows into the rear opening. This was not the case. At least until 80 MPH. The air flows up from the engine, out the decklid opening.
