Just an old fart from Florence Oregon

As long as you can properly support the input shaft it should work. In the car it came out of the trannies input shaft usually rides in the end of the crank on a bronze (usually made of that) bushing. This supports the trannies input shaft dead on. If you get that shaft off center much it will likely have issues with it. If you did not cut the bellhousing off as Arrowhead did then you could not get a straight shot at the input and the hondas I have looked at with motors off had pretty short tranny input shafts compared to the VWs I was looking at before. I wonder if the Honda is better supported inside the tranny VS say the VW jetta type trannies? (I know they face the opposite directions. But the VW may work great for a sled motor with a CVT that already has a long jackshaft to stabilize the driven CVT. Then a sprocket down to the VW input. The Honda really favors the bike motors due to the way it faces. I saw one MBNer on here who wanted to feed right off the bikes output shaft into the VWs input shaft. If it did not offset the motor OR the tranny to far that would be a heck of a setup.

I guess my thinking is custom splined sprockets would cost more than a good quality made adaptor that fit a common sprocket you could already buy that fit your adaptor. Maybe not if you got a line on good custom parts?

Plus a person building their own adaptor might even be able to use the clutch disc plates inner springs to help cushion a hard hit. The springs take a hell of a bang when you try drag racing the full size car. They may be to stiff to give relief in a small buggy? Lighter ones could likey be found if this was a desired thing. Instead of connecting diretly to the spline part like Arrowhead did you would have to weld on a disc to your sprocket adaptor that would then attach to the clutches outer circumfrence. Just an idea. Might not be worth its trouble. Bill

laser cut the sprocket and be done with it...

Something I was thinkin about.

I would make sure that whatever tranny you use is known to handle about 4x the torque of whatever your bike motor is putting out. After you factor in your primary reduction and then your 1st gear reduction you will be around a total ratio of 4. This is assuming you are running 1:1 on the sprockets. If you have more reduction there, then you have that much more. If you plan to run 2:1 on the sprockets your 100 ft lb of torque busa motor will be up to 800 ft. lbs before it even hits the tranny on a first gear launch. I would avoid running any reduction in the sprockets. I think this is why the trans works stuff has had problems. The old VW components just can't deal with the mechanical advantage of all the gear reduction prior to the gearbox's input shaft. A honda tranny has been known to deal with more which is why I am guessing arrowhead's is staying alive?

Make sense?

I see where you are coming from Standfast.

Arrowheads machine is quite light and toss in sand (even big paddles slip) Its all in all likely a lot less than the tranny ever saw in the car.

I wonder what kind of forces a tranny like that actually see in the car when some kid ( no matter what his age... :] ) Revs the motor to 6000 plus rpm and sidesteps the clutch. The twenty plus pound flywheel and some wide sticky tires on pavement gotta make for some real jolts to a tranny when this happens and you know it happens many times over for a lot of cars. Some of those honda motors are not slouches in the power department either. especially the newer ones. Bill

That would work for a low HP setup but you still have to support that input shaft because of the tremendous side load as the chain is trying to pull the shaft sideways.

I snapped 2 inputs before I supported the keyed shaft on BOTH sides of the sprocket s all the spline has to do is turn the Honda input shaft

It finally seems to be happy

What model '88 Honda model did the tranny come from? I've looked around a bit here and haven't seen one that matches yet. That's a great set up ... I love the DIY stuff.

This is out of an 88 Accord which is a little tougher than the 78 that I used first but any Honda will work

Weasel dropped to check it out today

[whiplash]

Hey Arrow still no vids of this beast?? I really want to see it in action!

[weasel]

There's so much buggy action goin' on in that Florence area it's just a blur on nice days. He lives right next to the dunes, just an arrow's flight from where they launch those monster dune buggys hauling about 30 to 40 people at a time.

I'd move down there if I liked runnin'on sand, it's the real buggy hub on the Oregon coast.

I have no doubt there's plenty video but nuthin' see's as good as your own eyeballs and the thrill in the pit of your stomach.

He's an active man, every buggy is ready to go on a moments notice from what I saw.

Sorry the video deal just didn't work out last weekend but I'm due to run with the mini's for the first time this weekend so hopefully we will get some then
