    throttle bodies

    anayone try boring out there throttle bodies, or finding bigger throttle bodies from a different application that would fit?

    I just think that the stock 36mm ones could be made bigger or something. everything we are doing to our skis, to allow more flow, and we have those restrictive TB's I don't think fuel will be a problem with the EFI, we just need more air.

    I think someone needs to try to have them bored out. Abbott, do you still have your old EFI stuff? maybe we can test with that stuff.

    The stock EFI TB are 40mm and I have checked into this already. There is not quite enough meat to bore them very much. Plus EFI is more efficient than carbs so you dont need as much CFM to make the same power as carbs.

    I have found some TBs that are 48mm from a snowmobile w/a return line port. I dont really know how much you would gain.

    Kerry tried to bore out RaceRobs awhile ago, but didn't have much success. Rob went with carbs.
