Hi Mark, Yes - I tend to overcomplicate.
Could you expand/explain why this won’t help: > http://www.greatplainsas.com/bf2004.html > <http://www.greatplainsas.com/bf2004.html> Its not the full Wasserboxer - just the head, just like the Rotax 912. I keep reading that the VW is heat limited and heat stress the cause of many to most of its reliability problems. I don’t know how true this is. It makes sense, but I could imagine that perhaps multiple issues including poor manufacture tolerances, poor metallurgy, and just plain bad design contribute - perhaps. The Rotax 912 has developed a fantastic reliability reputation - pretty unexpected based on my experiences with Rotax in the early 80’s and the fact that it runs at 4-6K RPM through a PRSU. Clearly new Rotax engines have WAY better manufacture tolerances, metallurgy, and fantastic design - clearly. Ha. They reliably pull 100hp from that little engine - a feat that would melt our VWs. I really don’t have much experience with VW’s, but I’m trying to learn. So fill us in on the water cooled heads. Perhaps I’m flogging a dead horse (or hp;-), but I’d love to see a reliable VW. Cheers, Owen. PS - I’ve ben reading the AreoVee forum. Ouch! Some pretty unhappy customers. Perhaps as you say, keep it simple and keep it Revmaster. > On Mar 1, 2018, at 9:00 AM, krnet-requ...@list.krnet.org wrote: > > Message: 8 > Date: Wed, 28 Feb 2018 21:12:27 -0600 > From: Mark Langford <m...@n56ml.com <mailto:m...@n56ml.com>> > To: svd via KRnet <firstname.lastname@example.org <mailto:email@example.com>> > Subject: Re: KR> Waterboxer Heads > Message-ID: <00b4b703-d806-ca12-901f-ec9630b09...@n56ml.com > <mailto:00b4b703-d806-ca12-901f-ec9630b09...@n56ml.com>> > Content-Type: text/plain; charset=utf-8; format=flowed > > Owen wrote: > >> I've been struggling to come to terms with the reliability issues > common the VW conversions.
