15.1 high torque gear ?

welderboy

Ok I am in the planning stage of my build, and am having trouble finding information on the high torque gears. I am looking at putting a 8" lift and 25 or 26x8x12 on my mid 90's club car. I know the stock motor will not want nothing to do with them large tires. Can anybody tell me if adding the torque gears will offset the larger tires and keep it drivable there are couple good heels in the hood I would still like to drive up? I am not looking for speed by the way just want it to be drivable. Sorry if the info is out there been looking and can't find it. Thanks for the help!

I would say that should help correct the larger diameter tire's affect on the final drive ratio. Think of when a truck is lifted with larger tires: The best thing to do is change the gears to compensate for the change in final drive ratio caused by the larger tires. You can compare the ratio of changing tire diameters to the ratio of planned gear changes to give an idea of how close you will come to a near stock final drive ratio.

Thank you that was my thinking. It seemed to me that it would not be any different than with jeeps ( my other love) . Just wanted to see if my thinyking was correct if my math is right its still a little lop sided for the carts the tires would be on the tall side a little.

That or you get a clone 420 and drop in there with the lift, lol. But yes you are correct, there are various calculators on the net that will tell you. Most stock carts don't go over 4K rpm and some go 5K without a governor. Most cvt overdrive .9 ratio but I don't know about CC the clutches are a little smaller. With a yamaha that turns a ~13 ratio trans into ~11:1 final drive ratio engine to axles, for the top 'gear'. You can also mod the clutches a little to help like by getting the secondary machined (cut sheave). You could try that first. Can also get springs for the clutches but the cut sheave I've used and it actually gives a lower gear, it would help no matter, I can even tell its there with a clone engine and it helps spin the clutch up faster. I can do a donut with that cart from a stop with 22s on it, in a dirt drive. I have to get video of that this spring.

Thanks for the replys I am actually looking into the 420 clones right now. Seems to me I would gain more from the clone for not to terrible much more money than the gears.

That is what I am getting at. It is a project but lots of help and posts here on it, if you can manage to do it. People don't even run torque kits in the clutches with them. The issue with the one I did is traction you climb or tow and it will spin a tire and dig a hole, posi becomes something you really want for that kind of stuff. A stock clone runs about the same top speed with no governor, just break it in good before you hammer it, but I'm trying to beef mine up a little more to catch a little more rpm still using stock cam. I will be able to compare it to the stock one. Stock but that one does have a larger exhaust and intake/air box and jetted much richer to run. There just is no substitute for power, riding the clone cart is amazing compared to stock yet it is not outlandish it just feels like two engines in there. I just bought mine for 250 plus tax, no shipping at home depot online, but I got a recoil I plan to keep the generator and make it start just like stock. One bad thing they don't charge the battery very well, I think only elec start charges at all.

I am a welder by trade so I think I should be able to fab the brackets. From whatz I have read so far I will be keeping the generator. I want to keep it as stock as possible just with the larger motor but starting like normal. I read about people us the stock clutch one the 420 does it have any problems with the extra power? I don't plan on modding the motor for any extra power stock should be plenty, and I would like to keep it reliable.

How hard is it to keep it starting like stock ?

For my G9 it was not that hard, I made 3/8 x 2" bars to bridge the stock mounts as the yamaha engine hangs between them. I put a 1.25" sq tube across the front to lower the front and level the clone (due to lift making it on an angle). I messed with it to get my same measurements between the clutches and mounted it up. Some people move the generator to on top of the engine. All you need is the gen, wiring, and a clutch with the pulley on it. Get the taper adapter from CPP for $50 or so and use stock clutch on the 1" shaft. I used a common bosch relay to kill the engine when I let off the pedal, wired to the original power for ignition. Just have it ground the clone coil all the time unless its powered up. If your cart has 12v ignition, if it don't then it may use the same deal as a clone and only need to ground that wire to kill it.

Some CC are CW rotation they run backwards, so you have to figure that out. It would run in reverse if you have that and reverse is a lower gear. IIRC newer than 93 do that but I'm not sure. Some put a jackshaft in those to get around that. Nobody has had a cam made to run a clone backwards yet, it should since it is a splash oil engine.

I just checked and my cart is a 94 so the motor is the counter clockwise. So I guess I will be runnin in reverse. From what I gather it won't hurt nothing and 26 tires won't bog it down to bad?
