As far as a cheap stretch I've seen those adjustable swing arm extenders anyone have feedback on the strength of them? I do need to find a dyno to tune. My s2000 was great I put a blower on it and tuned it on about 10 pulls on an empty street at 2 am lol. Don't have the luxury of a passenger seat to put the laptop.

 

While I'm not sure how bad the lag would be, it seems Volvo turbos are a some what popular choice for some sport bikes - here's a 600F4 with a S60 turbo on it.

 

Hm I would think the gt15 would be a better fit but if it works it works. Just depends on price. I want something to spool quickly with a lower psi.

 

if you extend the swing arm there will be plenty of room, surely there is a way to put a supercharger driven by the rear sprocket??
