I was watching a show about the making of Disney Land and they have a show where they drive cars around... The cars have street bike engines in them, and this got me thinking. How would you go about doing this? How would you get a transmission to work on this?

The cars they used had custom transmissions so they had 4 gears forward and 4 in reverse, so is there anyway to use a normal transmission for this since I wont need 4 in reverse?

Just an idea I thought of, doubt it would work, but thought I would ask.

if its anything like the golf cart we are building (Yamaha FIZZER 600), we are going to get an ATV solid rear axle with a sprocket and adapt it to the carts swing arm suspension and it will be chain driven. If you ever get a shaft driven bike motor you can weld up a driveshaft that will adapt the shaft drive on the bike motor to a car style rear axle with U-joint etc.

I attended that show in the Magic Kingdom last month. I think they are R1 engines. The cars are some euro car that has been lightened and they have like 3 inch wide tires on them. They always dumped the clutches and spun the tires. Also I noticed about 10 pallets of tires for them as I waited in line.

Yeah, they run the pressure really high so I think they said the tires last about 2-3 shows... lol

I was thinging about the R1 engines since they put out 180hp. Just didint know how to get it to work on a stock truck axle. If the R1 is chain (maybe belt) how would I go about doing this?

I dont see a chain being a good idea on a truck, and what kind of axle would I use? I dont see an atv axle working. If the engine was wounted in the bed that would make the chain shorter, but still the problem of what kind of axle.

Are there any shaft driven bikes out there that put out a higher HP, and would the transmssion even be strong enough to put the stock axle?

Thanks

We run bike engines in Dwarf Cars for racing. There is a company that make driveshaft couplers that go where the chain sprocket is and you have a driveshaft made. Look up dwarf cars. Two sites are http://www.cdcra.com and http://www.vradwarfs.com

was just about to mention dwarf cars. I've never really looked at what setup they use but I know they run a bike motor and they are fun as hell to watch at the local track.

the reverse part of it sounds interesting. its obviously a separate gear box who's only function is to convert the forward gears into a reverse gears probably at 1:1. I'd like to see how they do that.

I have built and raced Dwarf Cars for several years before stepping up to sprint cars. They are the best bang for the buck as far as dirt racing goes. Now the forward and reverse gears is easy. Allot of the bigger sail boats run 4 cyl diesel engines and have a transfer box. It has forward, neutral, and reverse. It also comes in several ratios, but 1:1 is most common. Did I mention I used to race sail boats also.

i dont know jack about honda's but I believe their motors (if not the rest of the drivetrain too) rotate in the opposite direction than most other motors making it impossible to bolt a honda motor up to a TH350 or like trans for example. somebody jump in here and correct me if I'm wrong.

an adapter and the 1:1 boat trans (or similar) that luvrv8 is talking about is most likely how it was done for the cars on that show.
