Its an Eaton M45, perfectly suitable for using on something else, you can buy adaptors for the inlet and outlet to get normal pipework onto them easily.

They are good for around 200bhp, you need to get the gearing right though.

On something like a Zetec motor you would want to be gearing it about 2.5:1 so it spins quick enough when the engine is only doing about 7K rpm, obviously if using it on a bike enough though by comparison you would get it more like 1.5:1

What application are you thinking of Neil?
