Hi Mark, Forgot to mention that Rudi Greyling' KR as per the KRNet link recently took part in a race against a Pioneer 300. Can't remember the distance, but definitely over 200 miles. His average clocked speed there & back (both ways, no tail wind influence) was 185mph using a Turbo Type IV VW.

It's at least twice as tall as the stock distributor, closer to 10", and twice the diameter, unless there are others than the one I remember being the rage in the early VW racing days. > I've read somewhere that Roy Marsh' stretched KR2 wings joined at the > fuselage. I.o.w it was tapered from the fuselage. I'll leave the Roy Marsh questions to Bruce, but it's a different airfoil than the plans call for and is also thinner in terms of percent chord. It also had a higher stall speed and landing speed than a stock KR. People are often impressed with the roughly 192 average mph speed that he scored in a race, but consider that his engine was turbocharged, and it may have been a one-way race like Airventure Cup, where a tailwind can make your speed look really good...
