I must admit, my thinking coincides with yours. I have actually cut two 40 x 15 mm (1 3/4 x 3/4') narca vents into the intakes just as they start curving inwards. Very much like we use to do with the fully ducted, ducted fans, ala BVM. I believe this will allow the air pressure to drop enough in front of the turbine during flight and thereby also reduce the drag it may cause.

I agree with you too. The intakes are not large, but not particularly small either. I was thinking I'll run it on the ground and then decide on whether to cut a further two narca vents on top of the tutbine in the bypass, should the bypass run too hot on the ground. This I hope will allow hot air, directly around the turbine, to be sucked out from the bypass - by the air coming in from the two narca vents up front.

Anybody else with experience of a small gap around the turbine in a bypass?
