I have no leaks in my cockpit. I have sealed, with old inner-tube, all 
of the holes into my cockpit and put 1/4" foam around the canopy for 
the winter. My NACA cockpit vents work very well at all speeds even 
high speed taxi. As a matter of fact, in flight, about 60% of my 
cockpit noise is from the NACA air inputs.
