· Must run full metal side shields around engine
· Turbo will be fitted with a shut down guillotine on the compressor inlet side. Must be able to shut the engine off.
· Full face helmet required
Special Note**
Due to the multiple manufacturers of compact diesel engines, and the different cubic inch size in each, there will not be a bore/stroke restriction other that a 100 cubic inch limit. The cost to pull the head off of a 3-cylinder liquid cooled engine is not something we want to do at the track. It is the intent to let the drive line and transaxle to limit the amount of usable power. Also tire size and weight are the reason you have been granted engine freedom.
