Larry. I owned a 54 VW and the instructions for that car, were to run
the engine to high rpm before shifting to a higher gear. Instructions
were to keep the rpm as high as possible. Don't know about the later cars.

In the case of the VW and Corvair I think we've learned where the
failure points are in using them in the KR. VW= carb's (a friend was
killed, engine quit, tried to turn back) heat / oil temp, valves,
engine case. Corvair was cranks but that may be corrected. I think
others had problems with internal gears, harmonic dampener, etc. The
problem as I see it is the engines are run outside their design
envelope and exposed to stresses they weren't designed for. No
different than the time I took a toilet bowl brush, taped it to a long
stick, and cleaned the debris from my gutter guards. Yes , it worked,
but...it did a marginal job and didn't last long. Certified engines
quit too but they were purpose built to handle the stresses that we
put them through in the environment we use them in. In our case it
boils down to your risk tolerance. What are you comfortable flying
behind? As long as we are free to "experiment", there will be
"experimenters".
