Gotcha. My friend must have swapped his (or?). I thought it was odd that Kawi would do that. Except the new Brute does have 4/110 studs. So, it didn't seem too weird after that.

 

I don't think the wastegate is what is going to need to be sized for RPM, as much as the turbine and compressor wheels to make sure its something that will reach full boost quickly enough, and flow as much air as possible. Sounds like a fun project.

The Dyna has a 9200 rpm rev limit. You might also want to pay attention to how much advance it has, it may be too much if you are running a turbo.

If he were running too much timing for a turbo could he just install a 4 degree offset key backwards thus acheiving 4 deg less? He could then keep the Dyna.
Just a thought.
