How have other builders dealt with the relative trimming of the upper cowl inlet air ramps and the forward part of the baffles. Also how did you trim, mount and form the airseal at these interfaces? The plans are very one-dimensional.

I set mine up so that the inlet ramps (attached to the top cowl) were wider than the baffles. That way, the seals on the baffles just reach up and then bend inward as they hit the top cowl ramp.

When I originally built my baffles, I thought the sides of the baffles were supposed to "bound" the ramps on the top cowl. I had it backward. The ramp should be wider than the baffles.

Not sure if that's clear as mud or what, but here are some half-as s pictures:

Hope this helps. Best thing to do is go take a look under the cowl on an RV that you trust is reliable and FAST. Short of that, beg for some more photos on the web... :rolleyes:

Thanks Dan - Makes perfect sense and sounds like a plan.

I was hoping that there was a simpler solution though :)
