i found this golf cart but it's way too slow. how do i make it faster?

this is what the insides look like. my budget is $0. thanks in advance for your suggestions

some great suggestions itt but unfortunately like i said there is a budget here of $0. my original hope was that i could just switch the batteries from parallel to series but that's how they are already. it's absolutely tragic that this golf cart won't drift at all. like even hitting a 90 degree corner full-throttle on gravel at the bottom of a steep hill, nothing. this must be what it's like when you're old and your dick quits working. even tied to the corvair it won't spin the tires

Find a really tall hill. Push.

i tried this one, but the golf cart wouldn't make it up the hill as-is. i was tacking back and forth and it was super lame. new batteries aren't in the budget but i will be cleaning the connections today. yesterday i tightened up the steering, brakes are already great. except the parking brake is like built into the brake pedal and i set it by accident sometimes which sucks.

my initial googling hinted that there might be a governor to remove, but it sounds like electric carts don't have those. this link had some helpful suggestions, but unfortunately most of them look like they'll cost money. #4 was bigger tires = more top speed, i'm going to see if the trailer tires i saw in the field yesterday will fit. #2 is a cleverly placed resistor? sounds promising, but i'm not sure exactly where it goes.

i want to smoke tires so badly. i will humbly accept any speed parts or advice and offer to livestream my death by golf cart in exchange if we can get this thing going fast enough to kill me

Hey, I just finished phase 1 of my golf cart project. So far It stops/goes and I can use it to tow my little landscape trailer, I spent way more than $0 however.

What does the water level in the batteries look like? Make sure you use distilled water if you need to add any, its cheap enough. Take apart all the battery connections, wire brush until shiny/clean, reassemble with electrical grease. Make sure the tires have good pressure and aim downhill. That's about all you can do for free if you already have the wire brush and the electrical grease. Bigger tires wont do anything if you already don't have much power, it will just suck more battery current trying to spin the motor against even greater resistance.

If you do a resistor across the field terminals on the motor you will need something pretty big, with my old resistor speed control and my clamp on meter in inrush mode I saw 220ish amps from the battery and 60ish amps continuous at full throttle/full speed on a flat gravel driveway. Without getting a calculator out I can tell you for sure that you will need more than a 1/4 watt resistor.

From cheapest to most expensive you next options are probably upgrade your cable size, change your controller, change all your batteries to 8V or find a place to stuff two more 6Vs, and if you still have money left over you can change the motor.

thanks for the advice man, i really appreciate it. water level in the batteries was super low so i topped em off, $1.06 on a gallon of distilled water. scrubbed the terminals and connectors clean with an old grill brush but they wanted $10 for a tube of dielectric grease at the napa in town so i didn't use any. it doesn't feel any faster really, but seemed to maybe handle the hill a little better. probably just wishful thinking

i'm really interested in the resistor thing, but also woefully ignorant. it sounds like One Weird Trick to go fast if you don't care about your motor, which is perfect for a free rusty golf cart that is too slow to enjoy as-is. can you tell me anything more about it? maybe even what to buy and where to solder it?

i was kinda bored with the cart on account of being able to easily outrun it on foot, but an inspiring series of renders got me fired back up again
