I would guess that the Bellhousing is literally the perfect mount for the bearings needed to hold it straight. Its not that far off the front of the tranny. Bolt a flat plate to it and bore a hold dead on the shaft for the bearing housing and then add stabilization fins. But thats me. VW trannies to hook up well built VW's (and last) are usually a good few bucks. Audi transmissions are far stronger but heavy. I am wanting to go find and Audi and measure it for length. I do not doubt an Audi tranny would hold up well to the power of a Hayabusa though. Especially if the car was light. Built VW 091 with Weddle parts are capable of 300ft.lbs. torque input.Not to mention that ANY 90 degree power transfer (like a ring and pinion) is MUCH more parasitic drag than gears running in parellel. This drag gets worse as speed and power climb.I agree completely but are stronger by far. Makes one wonder if a simple square aluminum box (budget) or a fancey case (high end) three gear box could not be made to couple directly to a bike motors output shaft then send power back to where it feeds out to the car tranny. Instead of fancy gears take VW gears right from VW as they are already made and cheap (compared to making) It sounds sooooo easy! Others have done that with varying success. Yep,it SOUNDS easy. I have heard that the street bike Vmax is a shaft drive. But the little part that converts the power from the motr to the driveshaft can be removed and it can be made into a chain drive. IF this is true you may be able to use TWO of those to get the power to the tranny but you get a lot of drag compared to a chain. They are tough as Vmax street bikes are brutally fast. But stock Hayabusa being newer and faster may still be able to put the hurt to them. Open chains SUCK. The quest is to avoid them if at all possible. IMO a built or t'boed busa with the added weight and drag of a mid size buggy would kill them. Just toss all the chains and gears in the dumpster and put a hydraulic pump on the motor and feed it to Hyd motors at the wheels. I always wondered about this watching HUGE bushhogs with hydraulic spun blades. They spin those massive steel discs of knives up to speed brutally quick. And they hit some dang good RPMS. Just need a big oil radiator. And talk about parasitic losses!!! Then I think back to a Vmax street bike or a Honda gold wing. They have a small and lightweight 90 degree drive at the rear tire. These are VERY strong as most of you know. Set the Hayabusa sideways in the chassis and feed it into one of these then into a Hondas car tranny. You would have to fab the adaptors but NO CHAINS.
I think they used a type 1 so the could flip the ring a pinion for a mid engine application
I think its a great idea. A built bus box should be able to handle 300hp and the lower torque #s from a bike motor will help not killing the trans. If I did this I would make it a rear hanger and not flip the box. I wanted to do this and was talked out of it by a couple of trans shops and a couple of forums. A bus box in standard configuration is a well proven setup. I woud love to see one of these setups.
