Does anybody know what the CFM intake air flow is on the rotary?  I am thinking about the size of air filter I would need.  For instance, what size K&N filter would I use?  I would like to provide ram air thru the filter.

I was considering the conical type filter, but it looks like the size of it may be a show stopper.  I am pretty limited in the space available for a filter and do not want to make too convoluted a path to the throttle body.  What is the best guess on the number of square inches of filter required?

Any help would be appreciated.

Thanks,
