Anyone Looking For a '185' ZZR1100?
Discussion
Not planning on changing any internals... taking my lead from the ZZR bike-tuning boys - low boost is (apparently) safe for 225-ish BHP on stock engine.
Got a great deal on a variable-vane blower and ZZR manifold, so will keep install costs reasonable (and WELL below the cost of a Busa install).
Will let you know when it all goes horribly wrong and the engine explodes... lol!

I don't know about yours but as my 1100 is running a big bore kit and 13.75/1 comp ratio can you still run a turbo? or would I need to reduce the comp ratio first.. I would have thought the standard rods were a bit dodgy?
Stick a turbo on a an engine with a comp ratio like that and it'll be atomized; 'starting point' for four cylinder turbo engines is usually a compression ratio of around about 7:1: I've come across turbo Kwacker engines running just over 9:1, but it usually involves some very special (and appreciably pricey) kit, pistons, rods, cranks, water injection, clutch etc etc.Turbocharging bike engines that weren't produced with turbochargers and started life with a pretty high compression ratio is pretty specialist even compared to car engines and frankly, I'd stick to tuned naturally aspirated. IMHO going turbo on the premise of cheap power is usually an illusion.
.............or run it on methanol?
This could be an option worth exploring with a specialist eg TTS
Methanol has a reputation for causing fuel system corrosion but I suspect that this has much to do with its hygroscopic qualities. By adopting non-atmospheric handling regimes that border on the obsessive, a friend has run a Honda VTEC on methanol for many years with no apparent fuel system problems.

AFAIK my engine has the stock 11.0:1.
Will be lowering the CR considerably (most probably with a spacer - not the best solution, but if I get a summer of turbo fun out of it before it gets completely shagged then I'll be more than happy)!
Busa for next winters upgrade... just can't afford it at the mo!
