One more thing I thought of.....

the ram air intake may yield you a bit on the dyno, but it should really shine at speed....when it is actually providing a ram effect! Too bad we can't get "in the field" measurements to see what the ram air does when "working" at speed. That would be cool. I bet when you are at speed, your HP increase is more than 38.
