If more air comes in than can go out, for instance at speed, nothing moves =
and there is no cooling. There are only a few ways to get air out from und=
er the hood on a TR, some cowl work, side vents as on factory racers and th=
rough the bottom. With coated headers most of the heat goes down the pipe =
and the electrics are not that sensitive. Only fresh ambient temp air reac=
hes the carbs. I have raced this setup at well over +100f/38c and all was =
good (water and oil temps). Less air in means less exiting under the car w=
ith lifting and turbulence causing drag.
Hey listen, its more work and complex, likely worth only a tenth or so. Ka=
s liked it and it was fun to engineer. Have a great summer racing, Ken

I'm not unhappy to have some fresh air under the bonnet.
It cooling everything, exhaust headers, electric, carbs, and stuff.
If all is closed only hot air comes in.
No advantage I guess.
Cheers
Chris
