Yes - I tend to overcomplicate.
Could you expand/explain why this won’t help:
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
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.
PS - I’ve ben reading the AreoVee forum. Ouch! Some pretty unhappy customers.
Perhaps as you say, keep it simple and keep it Revmaster.
