Yes, but show me a standard VW head that does not melt down at more than an
honest 50 HP continuous, and I'll change my tune. *I don't think I'll have
to buy a new songbook anytime soon! *They just can not get rid of any more
waste heat than that.

Hoover write's about thrust being more important that HP. That jibes
with other stuff I've read.

The christmas engine blog sounds like he's doing all this direct
drive?

Can you really get max HP out of an automobile engine at lower RPMs
required for a prop not to spin too fast? Don't you pretty much have
to have a PSRU to match max auto engine HP to sub-sonic prop RPM?

Well, okay this should be asked over on homebuilts. Anyway the OP was
all about having fun in low n slow. I think these guys are
outrageously low n slow.
