Golf Cart To Go Cart!

[infidel]

I traded one of my rifles for this 1998 Yamaha electric golf cart.
My family goes camping alot so I decided to get rid of one of MANY rifles to start a golf cart project.The goal was to strip all of the electrical wires,motor and battery out of the cart and install a 6.5 hp gas engine in.I lost a LOT of weight removing all of the batteries and motor out. On the rearend the shaft will spin 9 times before the rear wheel makes 1 full rotation. I had a feeling that the motor and rearend were not going to work out but I tried anyways! After i mounted the motor and got a chain,clutch,and sproket I tested it out and when i first accelerated it took off like it was going to pull the wheels off the ground, but then it went like 6 mph at full throttle!
Not going to cut it at all....Now i bought a rear differential from northern tool and im going to install it into the cart BUT i dont know what sproket to get.
Also when i removed the rearend now i have no brakes,so i need to install a disc brake setup on the rearend,also dont know what hubs to use that will match up to my golf cart wheels that i believe are 4x100 pattern.
Alright here is the cart

THE ENGINE

THE OLD REAREND I REMOVED AND LOST LIKE 200 POUNDS OF WEIGHT!!!

NEW REAREND

ANY help would be apreiciated I am stuck on how to properly mount the rearend and what hubs,sproket,brakes to use.
THANKS

those arent the right bolt pattern but you could use the whole thing or if your golf cart tires are 8inch rim they could go on there

BUT i dont know what sproket to get.

After you make your final decisions on the height of your back tires, you could use this speed calculator to help selecting your gear ratio: http://www.diygokarts.com/speed-calculator.html

The calculator said it will do 39mph, if its true that will be great!

Im looking into brakes and was wondering if i could use this brake caliper and mount it and use my 60 toothe sproket as the brake disc.Would it work?

Or would it be best to just get a disc and put it on one side of the diff or would i need 2 one on each side of the diff (one on each axle)?

WOW that is a good price!!THANKS
Would it work with my sproket being the disc?

 

[B man]

no cause the chain would b in the way.

 

[infidel]

Well the chain doesnt wrap all the way around the sproket the gap that the chain doesnt go on i will make a bracket to mount the caliper.

 

[infidel]

Would the caliper work on the sproket is basically the question.If it doesnt then I will have to mount a disc and caliper.

 

[DaiSan76]

I have seen build threads where people did that, I don't know how well it works. Why don't you want to mount a disc? I would think that the chain lube would make your brakes slip if you used the sprocket.

 

[infidel]

just thinking of a cheaper easier way.

 

[DaiSan76]

Well, I was thinking that Toystory had used the drive sprocket for his brake disc, but it looks like he just used a sprocket.

 

[infidel]

I guess i will just have to measure and see how big the caliper is and if there is enough room between the chain to mount it up. THANKS for the pic I need to see stuff like that to get ideas.

 

[DaiSan76]

You should read all the build threads you can stand. There's good stuff in all of them. Except maybe mine.

Just went to northern tool and picked up some hubs,bearing kit,and a drum brake.
