Looking for a good low cost engine options for your Kitfox?
This might be it (VW powered):

Sort of an explination about the VW Kitfox: http://www.youtube.com/watch?v=ficAqG07liA&feature=related

It's been pointed out that because the VW engine requires the larger cowling, and has a limited diameter, so it can't be all that fast. I agree with this myself, and am trying to verify the typical cruise speed of a Kitfox-4-1200 with the 2180 engine (note; a 2300 cc engine with aluminum cylinders is now available too).

In the mean time, I believe it to be about 100 mph at 3000 ft msl, based mostly on hearsay, guess work what the guy at the psychic hotline told me (Also Great Plains VW). Is that fast enough ???? Shoot; my Kitfox 2 with a 582 would only cruise at an honest 75 mph, so 100 sounds awful fast to me !!!!! (Note: The guy in the video is running a super climb prop, with a very flat pitch for quick off-the-field performace).

Really, my concern is the rate of climb, and obstacles 50 feet in elevation at the end of a short runway, cruise speed is secondary to me.

I am looking at installing a 2300 cc VW engine with low compression (7.5:1) so that I can run car gas. It should produce about 75 HP at 3500 rpm, which I think might drive a somewhat fair'ed Kitfox-4 at 100 mph, but like I said, I am trying to verify this with some other flying planes (I see a VW powered Kitfox 4 on barnstormers).

Agree?
