If you just want to make a VW or Corvair windmill, just lower the compression ratio to the same ridiculously low level that aircraft engines are, and you too will have a windmilling engine. From the Corvair's 9:1 down to the aircraft engines' 7:1, you'd probably lose about 10% of the power, but if that's all it would take to make you happy with the Corvair or VW, it might be worth it to you. Lowering the compression ratio is as easy as buying twenty bucks worth of barrel shims or head gaskets, and doing a proper "cc'ing" of the chambers, which is something every engine builder should do anyway. See http://home.hiwaay.net/~langford/corvair/valvejob.html for excruciating details on how to cc a Corvair (or VW, for that matter)...
