WD45 blower

In the 1970's-80's Dennis Lucas from Indiana pulled a turboed WD Allis nationally in the 5000 class and did pretty good..I'm sure that he broke some stuff doing it..About 40 plus years ago the Bentlage family in southwest MO pulled a turboed WD-45 AC that did pretty good as a state 4500 class puller..The tractor is sitting in a shed...There is currently another  turboed WD-45 pulling in southwest Missouri...I'm sure that Mack pulled one in the good ole days..Those 226's are some tough little engines if built right..

Seen reports both ways on them but Id guess the reason for opinions  would  be  the various expectations and capabilities of the buyers. Have seen the kit in person and did not see any issues with the actual parts.  I would expect that at stock compression ratios that only a very small amount of boost would require at least 91 grade fuel, maybe better and some ignition timing adjustment. A real good candidate would be a tractor with kerosene pistons, then you could throw some PSI at it and see a real HP change 

Drive train ultimate strength and working life is two entirely different things that is often talked about as one subject.  Is 100HP going to break a 4500lb WD45 the first time a load is applied? Obviously not as it's been done many times over the years. That doesn't mean you can build a 100HP WD45 throw a 5-16 plow behind it every spring and expect your grandsons to inherit it with an intact drive train
