Supercharging a GS
Does anybody know if it's been done.
Any links or pictures?

Number8 said:...possibilities are a diff alternator , or rework this one so it has a shaft of the back to run the blower ..
Number8 said:.......the plans have been drawn up to have a piece made up to house both injectors and a double K&N roundabout where the airbox was.
Number8 said:...Was looking at a rotrex C15 but having to find space for the inter-cooler would be a pain
sproggy said:I had in mind the same thing - driving the blower off the back of the alternator would mean no need to modify the belt setup, as long as the gearing was appropriate.
sproggy said:That's true. Modern blowers like the Rotrex are generally driven by 'ridged' belts of the same type as the standard alternator drive, but you might need to use wider pulleys/belt. This would mean fabricating a new belt cover but that wouldn't pose much of a problem. There might also be an issue with the belt tension required to drive the blower - this might overwhelm the alternator front bearing.
Number8 said:im aware of the inlectors being os far away and just hoping that it wont be to much of a prob , tbh with a blower i cant see how to get round it , unless u put it before the injectors and i dont know if that will work? will it ?
borrachadog said:Have a look at this http://www.marineturbine.com/motorsports.asp they say it does 0 to 227 mph in just 15 seconds
sproggy said:Quite a lot of turbo applications work that way - blowing fresh (or intercooled) air through a carb or throttle body (e.g. Maserati Biturbo). All you'd have to do would be to ensure that the system was airtight under pressure, perhaps using silicon 'turbo hoses' instead of the rubber links, and ally tubing instead of rigid plastic pipes.
Makes it much easier - you just need to mount an air filter (that will withstand the suction!) on the inlet to the blower and then split the outlet to run to to the existing throttle bodies (no change to throttle cables etc). As you said the injectors might not have a high enough flow rate at high revs but if you're only looking at a 30bhp increase they might just be up to the job, otherwise I'm sure there are Bosch alternatives (from a car) available off the shelf.
