What else?

txbonds

I've got the following setup:

2004 club car IS villager 2+2 (DS style body)
Altrax 400 amp programmable controller
3" jakes spindle lift
10" wheels with 20x10-10 all trail tires
4 guage upgraded battery wires running to motor as well
Stock IQ solenoid
Stock 3.2hp special service motor
Brand new 48v battery pack (8v dekka batts) reading 51.4 total and 8.6 per batt after 2nd recharge so far.


I've been using the cart with this setup for about 2 years now. It averages 22mph top speed on the flat and somewhere between 10 to 15 mph going up hill. Pretty pleased with top speed but wondered if hill climb could improve some.

After 2 years I'm replacing 2 Sahara classic front tires with the carlisle all trail II tires and will replace other two soon as well. Also got 5 years off batteries based on when prior owner installed before replacing this past weekend.

Anything I can cheaply upgrade for a little more torque or have I reached the happy medium of performance to price ratio here?

Thanks.

Maybe some pictures will help. :)

Here is cart as it stood a few months ago:



New 20x10-10 carlisle all trail II tires on front mounted today:


Rear 20x10-10 Excel Sahara Classic tires showing what I'm replacing:


I'm shocked at how much smaller the carlisle tires look to be the same size number wise. They are flush with the sides of the rim where as the Sahara tires overlapped the rim quite a bit. The front sahara's were completely bald so I'm going ahead and swapping all 4 tires to the Carlisle as I'm told they wear better on pavement.

So, other than wanting to swap out the top end stuff like seats, roof brackets and top for more modern styled DS parts, any one have any ideas on my earlier question regarding more torque without boat loads of money changing motor and altrax 400 dcx controller?

Thanks and hope the cart porn pics spur some feedback. :)

For more torque You either need to sell your controller and buy a higher amperage one (best choice)
Buy an upgraded motor (second best choice)
Or install shorter tires ( I KNOW you dont want to do that!)

Im running a 650 controller and a d&d motor and with stock tires it will go up any hill!

Your controller should be fine. And 20 inch tire are not that much bigger than stock. What I would do is upgrade the motor and then you have to determine what you want most, speed or torque or combination.

I had a 400 amp axe controller in my ds with the "bad boy" GE motor and it did 25 mph and had great torque on 18.5 inch tires.

You need a motor for sure so dont waste money on a controller.

Thank you both.

Any idea what motor makes sense to keep my speed in the 20+ range but increase torque with my 400 amp alltrax controller?

Im jaded of course because I have a d&d motor but I think they are the best. They consistently go faster than they advertise and make tons of torque while at it..
Here is a vid of mine with a d&d es 81-41 and a 650 amp controller. with Stock tires it does 28.8 mph on flat ,donuts in grass and go up any hill. Heres a vid of it

Thanks.

Mine would go up that sort of a hill without problem also. Where I'm looking for more torque is when going up a long sustained hill where my speed drops from 22 down to 12. Make sense? Maybe the answer is still the same but thought I should clarify.

Go here as it has the best desrciptions of motor options that I have found.

Also, GE does not make golf cart motors anymore and instead you would go with an Advance brand motor. And remember whoever you get a motor from that there is a difference between peak hp and sustainable hp as well as rpm. Advance motors are usually rated for sustainable hp while most others advertise peak. A 5hp sustainable might actually peak around 28hp.

Just did a test of battery pack. At rest this morning after fresh charge bats were 50.4v.

When first taking off at full throttle voltage drops to 45.5. After reaching full speed on flat it goes back up to the mid 47v range. Then on long sustained hill climb it drops to low to mid 46v range. When stopping it returns to 50v.

This mean anything good or bad with regards to setup? Any other tests I should run?

Also and this is a whole new topic I guess but I'm getting a real bad bumpy vibration at speed in cart and steering wheel. I had written this off to the old tires as the problem but now I'm wondering if the rims could be warped or some other problem.
