Supercharging An R1
#1
Posted 27 May 2009 - 01:18 PM
Just wondered if anyone has put a supercharger on an R1 powered mini yet? I've found a few references to R1 supercharged bikes but no car derived applications. It seems to me that most use a rotrex charger but which one I've no real idea. If someone has investigated or actully done it I'd love to know the details...
Thanks

most supercharged bikes use rotax type charger as small and gives good power

Shaun - is that a bolt on and go conversion, or would you need modified pistons n stuff?

how many years you known me and still spell my mane wrong lol
most turbo/supercharged bikes do one of two thing lower compression using either thicker head gasket or put a base plate under block raising block lowering pistons and compression
depends on how much boost would think know on busa turbos normally change pistons for hi boost
was bike at bike meet last night bike there with turbo and nos 400 bhp with out nos 100 bhp nos kit as well

Carillo do an R1 rod. They are around £200 each. Yep. Each.
You cannot shim under the cylinder body to lower comp ratio on an R1 - the crankcase and block are one casting unlike the Suzuki engine (other bike engines I am not sure about as I have only worked on Hayabusa's in the past other than the R1 engine I have now).
Thicker gasket is a possibility as mentioned, but personally speaking I think thats somewhat of a bodge. The head joint is usually the weak point in a presure charged enine. JE will do you a 9:1 CR piston. £600 a set though, and also they say you need a "special" gasket... I'm not sure what the "special" feature is; couldn't get an answer from the JE guy. It may well be thicker.

i head with bikes you have to do something like run superchargers backwards because of the engine layout... i think its just on V-twins? you heard of this before stig?
