its a turbo off a cummins v16 50 or 60L. im not sure which one. The engine is used for a generator. They have similar turbos that they only use one of on their 19L engines.
It is certainly not a water pump. But if it gets to 88mph it does make time travel possible.
my friend has a nice little turbo sitting in his room sized for about a 1L engine. i think it would be pretty sweet on the buell but i doubt he wants to get rid of it. it looks so tiny compared to that big one.
like i said before though i kind of want to turn the big one into a turbine engine.
I'd rather build my own kit like I did with my civic... That way I know exactly what I'm getting with each part and normally end up with a lower cost... I would prolly go for an AEROCHARGER turbo: no wastegate no turbo timer no boost controller so less bulk added to the bike
