REFLECTOR:MORE ON COMBUSTION AIR AND COOLING

[Chuck Jensen]

Steve,

Those are interesting values, however, I've found that at 220 knots in the
Velocity...never mind.

The Airflow Performance auxiliary air intake manifold does not have a double

butterfly system...That means that, when you open the system to ram air, 
excess pressure bleeds off back though the alternate air intake...You loose 
ram pressure...How much you say???...Well. that depends on how fast your 
going and the pressure differential in the cowl...Normally, about 1/2 inch 
of MP at 200 knots...Total MP at sea level, standard day, 220 knots in my 
Glasair is 32 inches...



Best... Steve
