Nigel, Yes I have a 914' but I am talking about the space
fed directly from a NACA inlet which gathers the air
before it enters the turbo. Like all the cowling inlets it
will be pressurised by the slipstream/propwash No doubt
post turbo the temperature will be higher still - which is
why 914s don't need carb icing protection.
Regards, David
