High Speed Gears...???

[dr.jim.b]

Just Curious... Does anyone have any experience in switching to Higher Speed Gears in an electric Club Car - I have an '05 Precedent IQ 48V Regen and the top speed seems to be right at 19mph (on flat pavement or slight downgrade). I'd like to get 5 to 6 additional mph out of this cart.
people have suggested: 1) Hi Speed Gears and/or larger tires. 2) Swapping out Motor and/or controller with heavier gauge wiring, etc.

I'm not sure which route would be more efficient - the cart is used primarily for golf but also for road travel in a golf cart community. Wouldn't want to give up a tremendous amount of run-time.

Curious to hear if anyone has switched out the gears in the rear end of one of these (Precedent) models and what (if any) the downsides of taking this approach might be.??

Thanks in advance for any assistance you may have to offer.

dr.jim,
Based what I have learned here, I would say forget the gears for now and get a 400 prog. Alltrax controller. I "hear" it will give a Precedent 24mph without compromising any torque(which regearing will do). It will actually give you a little more torque and speed. I know a couple of members here have had very good results, just upgrading the controller. Good luck.

Thanks..BS'r

I've read a bit about swapping out the controller but wasn't sure how much run-time (between charges) a person might lose... 10%? or 20% or...???

and I also haven't see if this 400 Alltrax controller must necessarilly eliminate the REGEN feature where the brakes help to put some charge back into the batteries.

If any of you folks out there can speak to these issues... it would be greatly appreciated.

Thanks Again!!

well as a rule nothing is free, add 10% to speed and it will come from somplace.
Bigger controller = more amps = More Torque, More Speed - less run time.
Bigger tires = loss of torque , more amps = more Speed = less runtime
Bigger wires = less heat loss (amps) in wires = more speed - same run time

But here is another way to look at it,
If you are covering 23 Miles in 1 hour
insted of 19 miles in 1 hour,
You will need to run the Cart less time to get from point A to Point B .
It's all relative.

Ahhh... some good points.

I'm thinking that perhaps getting bigger wires and slightly bigger wheels/tires might be the way to start. If I could get 22-23mph (instead of just 19), I think that this might be enough.

Someone else told me that if you switch controllers (i.e. 225 to 400 amp, for example) that you will use the higher amperage ALL of the time. In other words, whether we are driving the
cart on the golf course at 7-8 mph or on the street at 22-23mph... it would use the higher amperage level (say 400) and consequently reduce run-time even when only being operated at
the same lower speeds that the smaller controller is capable of.

Does this make sense to you? Is this your understanding of how these things work? I apologize for my lack of knowledge on these subjects - as I said earlier someplace on this thread....
I am a total NEWBIE to both this Forum and the world of cart ownership.

Thanks!! Again for your reply and the input/feedback.

That is just not true about using the max amps all the time.
If means you will get more amps with less peddle, so peddle to the metel point
changes :)

if you do a search of this and other golf cart sites you will see a lot of good things said of this company. I have never used them but all seem to be happy with them.

From what I have read of the precedents you can also add 20 inch tires without lifting them. this would also give a bit more speed.

Thanks, Aaron!

Yep! That's sort of the way I see the Co (EMP, Inc) too!

And, I also might (eventually) get the slightly larger wheels & tires.

Thanks Again for your input, Aaron.

check out plum quick i have a 06 precedent with PQ motor gps it at 25-27mph for 275.00 and you keep your stock motor,i didnt see using my motor as a core for only 50.00 and if you not going to keep your old motor 225.00 12"wheels 205-30-12 tires i just ordered alltrax 400 going to see what that will do, if not happy with that i will be going in the rear end plumquick.com they are some super nice people to talk and deal with

Hey Night.

That was a bit hard to read. Remember to break up your sentences a bit.

so you said. old motor is worth $50 bucks to them?

275.00 without a core
225.00 with a core?
