WOHM 5 TBR DEVELOPMENT

This is the very first WOHM "5" TBR diesel engine that we built. The case is machined from solid and anodized black. This engine was built as a test engine to establish a baseline performance data from which we could then change and modify the design to find the best overall performance for the least weight and simplest manufacturinf process.

This engine is the number 2 prototype engine and includes a number of design parameter changes compared to the first engine. This engine has a bolt on back plate and slightly different porting and timing. It also has a smaller case diameter in an effort to reduce the weight.

Here is the 3rd development engine is this WOHM "5" series of prototypes.
