Mark, that would be true for the VW Type 1, 2 and 3. But the Type IV is a
complete redesign of the VW case, complete with new alloy and thicker
walls, and much more. It was designed right from the start for high power,
with the Porsche racing cars in mind. The stock 2.0 liter, non
turbocharged, non injected, was good for 65 hp. There also is a rare 6
cylinder Porsche version of it which is pretty mean
This being said, if I could get my hands on a Corvair, I would build
something bigger tha a KR2 to match it! ;-)

And contrast that with the VW, which was designed for 46 hp (the most
recent
fuel injected engines were 60 SAE HP, but they used the "same" case), and
we
are asking it to put out 70-80 hp continuously, and then taking that power
out of the engine through the "pulley" end of the engine, which was
designed
to power only the fan and generator. As Bill mentioned, VW crankshafts
have
evolved to a point that greatly improves their reliability, but they still
break cranks, and the engine cases still have longevity problems. Standard
VW rebuild practice is to inspect the crank bore in the case for fretting,
and often they are "line bored" and oversize crank bearings are used to
bring them back to a useable condition. Corvair cases are so strong that
there is no such procedure, because that problem is virtually
non-existent.
