nice pics,are you sure that bilge pump gives necessary oil pressure to turbo?

 

Hi, looks like a fun project. I'm working on a yamaha turbo sled myself. A couple things you'll need to do are; put an expansion chamber in the exhaust with the turbo at the end of it, stock pipe will work. You'll have to fatten up the mixture as well, raise the main needle a notch and install a power jet. Route a tube from your airbox to the top of the carb, above the slide, if you don't, boost pressure on the underside of the carb slide may cause it to stick wide open. Using some sort of EGT monitor like a "digatron" to find the right mixture is a good idea.

 

Any video of it boosting?
