I'm using the Sam James "Holey Cowl" but it is the Lycoming version (IO -
360 without the bottom air inlet for Lyc carb), not the Powersport
version. Primary reason was to get the round inlets spaced away from the
prop hub where the air is turbulent. Another reason was the length was
longer to better fit the longer 20B engine installation. You can
trim the aft end to fit the stock Van's length if you want.

question
I have a James aircraft rotary cowl for my RV7. I have not got
it
installed yet though. I am not using the Powersport package, and the
only
issue with the cowling is that it was made to fit the powersport
package,
which moved the prop forward 2 inches. I spoke about this with
Will James
(Sam's son), he said the cowl could be cut and refiberglassed to
fit the
location of the standard Vans prop location, or use a two inch
prop
spacer. I was originally going to modify the cowl, but after seeing
the
excellent workmanship or the glass, I couldn't do it justice, so I
have
decided to go with a two inch spacer (Tracy has no objections to using
a
prop spacer by the way). I am using a Conversions Concepts Mount for
my
Renesis engine, and am waiting it return from the powder coaters. I am
not
sure of the prop location on the cowl for the RV8, but if you call Will
at
James Aircraft he would be able to answer that question for you, he
was
very helpful to me.
Hope this answers or at least helps with your question.
