My Setup, Will This Work?

[bgsengine]

If an axel has no differential, how are you supposed to figure out the speed?

if there is no differential, (I.E. a solid axle shaft with a sprocket or pulley direct drive) then one would a assume a 1:1 ratio - but same math is used as with a differential - if you know the input, and the gear ratio, then you can calculate the output . likewise if you know the input and the output , you can calculate the ratio.. and if you know the output and the ratio, you can calculate the input . Its all the same math.

if you have an axle and an input pinion, you generally would assume a differential , or at the very least a right angle drive, and ratio can be calculated by making a mark on input and output shafts and count the number of turns on input that it takes to move output 1 turn. Simple. It ain't rocket science.

Yeah i dont have the axel yet haha thats why and thank you! I am htinking about just getting a whole new go kart frame instead because this frame cannot work without some of the components i dont have... so thank you!

If you look at the axles I showed you...they have the diff built in . You change the final drive by getting a bigger or smaller sprocket....
They will run you about $120 and up..then you need brakes....
I was going to mention the whole new frame a long time ago....but you were pretty insistent on not listening....



And you really really need to think about gear ratios when you consider the size tires you want to turn. It's gonna take a lot of torque to get them rolling. This is why you want a TC, but even with one,I think you may find that IF you can get it moving...your buddies will already be on the green by the time you get up to speed. Especially on grass.....up a hill...with a golf cart body.

Since this thread has taken on a similarity to Frankenstein's Monster, "It Lives", it may not be wise to fuel the fire but here goes.

It has been several decades since being on a golf course or golf cart but many are far from being glass smooth. At the speeds you want to go flying across the course if you don't have an off road suspension on that thing you will crack open the family jewels.

Just another variable to toss into the blender.

Or, go back to the drawing board, throw in a Briggs 30 HP Vanguard, torque converter, and 28" ATV mudder tires, 1-1/8" axles, bolt on an 8" lift kit with suspension and six shocks per wheel, and call it "mini bigfoot" - then your golf buddies won't care how fast it goes, they'll still get the heck outta the way

Bo
Yeah i shouldve paid more attention to what you said. Its just that i thought i had all of the parts. When the golf course mechanic decided it no good, he took it apart, put all of thee extra pieces into a pile, and left it. Once i got the frame, i got all fo the parts, and realized that some of the screws and bolts are missing. Also the entire steering column is snapped in half (its almost a half a ft thick i dont know how that managed that). So sorry for not paying more attention, i can be a little thick sometimes.

Yeah i get what you mean i forget that it weighs lamost 200lbs

That would be a kick @$$ golf cart! I wish i could do that but 30hp... i make some money but not like that!

Hey also my friend, we were talking, and aparently he used to race go karts. He sai he got his little go kart up to about 40-60mph on a 120cc engine. Now i think hes pulling my leg but he insists it happened. Is a 120cc engine going 40mph possible?

[bgsengine]

Yes.

[TheWingnutSquid]

How?

[nevadawalrus]

2 stroke. While your Briggs red lines around 3600 rpm a 2 stroke just keeps revving to 3 times that.
