Default what is my next step to get this thing up to the normal 19 - 20 mph?

ok guys,

Took my 48 v 2006 cc iq ds (with 2006 trojan batteries) last week for speed upgrade - speed code 3 got me to 14 mph. I took my cart in today to get the speed code 4 programmed in. I watched the guy program it, his computer thingy told him I was only using 85% throttle so I watched him replace and explain how the throttle pedal linkage would wear down slightly. we even changed out the mcor to see if that would boost the speed any. we made several test runs today and finally got a max top speed of just over 17 mph ( I was hoping for the 19 blistering mph). i'm a little dissappointed.

so....I started the day off with a full overnight charge. It was probably about maybe 45 degrees today. (I've read that may affect it some).

I just checked the levels earlier last week in the batteries - all my readings with the walmart hydrometer were 100% charged. My last volt test was showing batteries at around 12.4 to 12.5, 12.6 12.8. and even the guy at the dealer said his computer showed the batteries showing 49 volts which to them was normal.

so.......I'm working on replacing the battery cables, lifting it and slapping on some 23" tires. (for maybe 2 mph increase???????)

aside from getting the $325 alltrax controller....do I have any other ways to get this thing up to the normal 19 - 20 mph? have I missed something in my reading and research?

thanks

Read the bottom of the first entry in this Sticky see what you think about your 12 Volt
Battery charge "http://www.buggiesgonewild.com/electric-club-car/1296-golf-cart-battery-comparison.html"

Bigger Wheels and tires = more speed , less Torque
Bigger better cabes = More speed and More Torque and same run time per charge
Bigger Controller = More speed and more Torque but less run time per charge.

Also make sure you do not have any Brake drag - every little bit helps

this maybe a stupid - how can tell if my brakes are dragging, i mean other than pressing and releasing - can i see the brakes if they are making contact?

Jack REAR end up unlock brake and see how free they spin.
the spin won't be as free as the front but should NOT be very difficult to turn
and no grinding or scrapping coming from brakes.

right Tom ,
it appeared low to me also , but not being a 12 Volt Man , and since the CC Dealer
told him it was OK , I just bit my tongue.
It's not a little low compared to 6 and 8 volt systems , it's almost completely Dead (running wise)

While we're on the question of controllers for Club Cars, I have an '04 Precedent 48 volt with a Curtis Controller. The model # of this controller is 1510-5201. When I took my cart to a CC dealer, they hooked up the hand-held communicator and got an error message, saying that there was no communication. They said I needed a new controller at $600.

My question is, is this a stock controller from CC, or is this an aftermarket device. Problem is my max speed is 12 mph per GPS. I'm about ready to buy the Alltrax DCX 400 IQ.

so for all you 48 volters, for 48 volt system (4 12 volt batteries) I should get a voltage reading from the pack of......???? 49, 50, 53 volts????? from a overnight fresh charge.

thanks for the help

I'm no expert on 12v batteries, but, voltage is read per cell in the battery. A 6v battery has 3 cells, 8v-4cells, 12v-6cells. At 48v you still have the same number of cells no matter which voltage battery you use. I would say you need approx. 53v for a fully charged batteries.
