I see a tag on the windfire, so they must be street legal.
I've seen plenty of those too Type 2 and 3 VW engines Frank. I disconnected a few wires, took the linkeages off, unscrewed 4 bolts out of the engine and pulled them straight backwards and onto a spare tire. VW engines of that time were the simplest and easiest engines to work on. The gasket set complete was $4. I'd love to have a few now.
My bugs would go 120 mph, fastbacks went 145 mph and still get 20 mpg. In normal driving, they got about 30. All had minor work and a mild cam to help them breath better. Thee are still small planes that use them. They did eat spark plugs regularly too.
