Super Cart

[Honda king]

I finally learned how to weld last week(iam a natrual)and i decided to construct a go kart(for offroad). i have the fram built almost.the motor i am putting on er is a 16hp auger motor. if u have any sugestions on how to make it go faster plaese tell(speeeeeed freak/old poo dont go fast enough)me. i may post some pic l8er to show. but i need princess auto right about now.. thanx

Buy my Yamaha Maxim, pull the motor out and drop 'er in the cart... oh ya...and hang on !!! :burnout:

[Always Muddy]

That would be a great idea actaully

[B Man]

wouldn't a auger engine have a verticle crank? hows that gonna work in a go kart?

oh ya, and check ebay for a polaris 800 twin, that should be quick enough for ya!

[Always Muddy]

A verticle crank would work not? a sprocket on the engine and then a sprocket on the rear axle and then have a chain turing it ?

vertical means up and down.....how are you gonna put power to a horizontal axle with a vertical crank shaft? unless you rig up a transfere case some how but i can't see it being worth it on a go kart.

On an auger motor the shaft is out the side to drive the belts. Put a smaller sprocket on the rear that should gear it up higher.

I think a smaller sprocket on the rear would gear it up way to high, it would be a dog at lower speeds. my buddies had go carts in their teens and they had larger sprockets on the back and still did about 60 mph.
Just my 2 cents.

the augur has the shaft on the side to dive the belts and i think i go with a medium size sprocket on the axel and a smaller one on the motor. if i go with to big of a srocket on the axel it will need a puch to get going. if i go to to small on the axel it with go slower wont it. i think a medium sized on the axel will do good. wut do u think

Wow sorry I wasn't thinking. Guess I should read better next time lol!

the motor he,s talking about is off a grain auger and not an ice auger but wow a 16 hp ice auger would be cool:cheers:

ya thated be sweet . wouldent take long to drill holes or to break ur arms

[DRIFTER]

Put a NITROUS system on it!!!

A big sprocket on the axle will be easy to get going but not much top speed, a small one on the axle will give you great top end but you will have to push to get going or it will just be real slow to get going.
Think of your old ten speed bike everyone had. if you put the chain on the big back sprocket it was easy to pedal but you didn't go very fast and if you put it on the small one on the back you could go faster but was harder to get going.
Good luck with the cart.:cheers:

ya somthin like that lmao... ill get pics tom hopefully

[sled_head_440]

Ideally I would try to locate a belt drive from an old sled something small like a scandic or elan, and insure they have small springs inside so you don't have to over rev to get going.

And to figure out axle speed is simple Drive/Driven gives you your ratio
ie: 10 tooth drive(motor)
----------------------- 1:4 ratio so at 2000 rpm axle would be at500rpm
40 tooth driven (axle)

And to to remmeber torque is directly affected by speed more rpms less torque

[QUADZILLA]

Check out the comet Torque converter Belt drive CVT system. Princess auto sells them for 3/4 and 1 inch shaft size. Gives you the bottom end you will want and shifts out for lots of top end. I think they run around $250 bux but I think only good up to 8 HP. Maybe Comet has applications for larger hp or maybe look for a smaller motor. 16 horse and a CVT would make a really fast gocart.

[Honda king]

thanx QZ ill look in to that some more.

[GrizzleyPeg]

Sounds like a great project. I think you need some sort of clutch at a minimum, and a CVT would be best. You could make it work if its geared low enough with a heavy belt drive and an idler pulley to put tension on and off the belt. Won't give you both bottom end grunt and top speed though.

Crazy thought. What if you had 2 belts driving it (or driving a shaft that is chain drive to the rear axle), and idlers on each belt. A big and a small pulley on the motor, a small and a big pulley on the other end. You tighten one and loosen the other. Gives you a high and low range? Have the two idlers on a teeter totter kind of pivot, one lets off while the other tightens. Push pull on a lever, forward is high range, back is low. You'd have a 2 sp powerglide.

[Honda king]

ummm ok lol. very complicayed. ill see wut i come up with

[B Man]

when are you building this thing?

[Honda king]

its already half built
