The usual schism between the Orthodox and the Reform LOL.

On the question of turbocharging a flathead. I have thought for years, that the flathead was well suited to turbocharging for various reasons. But in a discussion on another board someone pointed out that most flatheads suffer from cracking around the exhaust valve seat area indicating excess heat buildup.

If flatheads are prone to overheating in this area of course, a turbocharger will only make the problem worse.

The solution is to use a belt driven supercharger, either a positive displacement salvaged from a late model Thunderbird or Buick, or else a centrifugal blower like a McCulloch or Paxton.

Dick Datson has done some interesting work adapting turbos to belt drive. He has a web site I'm too lazy to link to.

I still think a blown flathead would be a very interesting project. There are a lot of angles to consider aren't there?
