Monty,
I believe you need to move the mouth of your scoop farther forward, as the picture indicates that it is currently at the leading edge of a low pressure zone.

Additionally, why do you angle the trailing edges of the strakes back towards the prop?  To my eye, this seems bad in that it (further) disturbs the air fed to the propellor, without any other apparent positive effects. Assuming you have no control surfaces on the trailing edge of the strake, perhaps you could use a curved trailing edge to address the intersection drag issue while still keeping the strake trailing edge far ahead of the propellor disk.
