I welded up some custom spindles and ran individual tie rods to each wheel. Toe can be set and Ackerman is now present for great low and high speed steering.

My electric go-kart on an American Express 2.0 yard-cart frame can pull 1G acceleration, but can it corner as well as a race-frame gas kart? Watch and find out!

Fat Guy on Electric Go-Kart (Short Drag Runs)
Переглядів 139Рік тому
I switched to using a Racebox Mini to log my GPS and acceleration data. It is absolutely better than using my previous GPS units. All stats are using 1mph rollout instead of the 5mph that I was using before since accuracy has greatly improved. I don't want to run this motor past 6500, so I ordered a motor with higher torque that will spin a bit slower and give me more usable non motor-grenade p...

I mounted a new 10Hz GPS to the kart and am able to get 10 updates per second instead of just one for better data. I also changed the gearing and hacked the controller software to increase field weakening for increased maximum and more sustained acceleration.

0-55 Speed Test KLS96701-8080NPS w/Max Field Weakening
Переглядів 92Рік тому
The new controller is installed and got some testing in today. It is a lot faster than the previous non-field weakening model (KLS72701-8080NPS). Times between speeds should be taken with a grain of salt since these are GPS data points and the speeds in between are interpolated. Controller: KLS96701-8080NPS w/Field Weakening Battery: 24s4p 38120HP Motor: ME1904 Gearing: 13/40 Electric Go-Kart
Gear Ratio Comparison (to last 0-60 video). Going from 2.57:1 to 3.08:1.
Переглядів 63Рік тому
Much faster 0-45 than the 14/36 gearing, but slows down to almost the same 50 and 55mph times (and no 60mph). I have a KLS96701-8080NPS en route with field weakening. Stay tuned for testing! Controller: KLS72701-8080NPS Battery: 24s4p 38120HP Motor: ME1904 Gearing: 13/40

Razor Dune Buggy Wheel and Axle Upgrade
Nice mod. I like the thumbnail image that shows the setup. Would would enjoy a more detailed video on this mod.
What parts did you use to make it go like that
I bought a 1000W 36V "kit" and regret not just asking how to copy this instead! Can you post some details on it? Your battery setup is so clean! Got the new motor mounted but can't figure out how to mount these 3 damn big batteries!
The major parts used are listed in the description. I have another video on the rear axle swap. I fabricated the front spindles with mild steel. You'll need a metal-cutting saw, welder, and a die to thread rods.
Can you do an in depth video about how you built this?
I did a video on the rear end. You will need that and improved steering before anything else. I can answer any questions you may have in the process.
@@EpsilonZeroKarts I saw the rear video. What did you use for the front steering links? I thought of buying the right hands side parts and mirroring it on the left, until that didn’t make any sense 🥴.
@@Nohoze I used angle iron, flat bar, and rod that I threaded with a die to fabricate the spindles. I also press fit an Oilite bronze flange bushing to replace the worn ones on the kart. Some regular tie rods connected to the pitman arm with the hole bored out a little worked fine.
Expert driver? What is that kid 6? All it takes is one car backing out of their driveway for this to turn ugly. Awesome mods though.
He has a couple more years of experience and has somehow escaped death so I'll be upping the power soon. If the kart does wheelies, he might be easier to see than just the headlight, wig wags, running lights, horn, and police lights that are on it now.
These look great! Can you provide links to the lights? Thanks!

Is that the ME1904 with a 72v100ah battery? Also what controller are you using?
It is a 24s4p 38120HP (Headway) 32Ah battery. The controller is a Kelly KLS96701-8080NPS.
dude that girl in the back was like wtf
_how much was eeverything in total and can u send me the link to all the stuff to build it
can you link the parts you used for this build?
Mannn those are quick! Invite me out lets race. 😂
Pretty close considering the EV is on a yardkart type chassis. Did you mod it to lift the inside tire when you turn?
Nope. I modded it with three axle bearings though so it can survive jumping raised manholes at 40mph.
I finally won at something! You’re gonna have to add some skirts and and a wing to beat me now
Nice!
Plaid Kart!
Check out the next upload for a 140lb driver instead of 253lbs. Just over 1G acceleration!
Maybe you can mount a bucket style race seat in there.
Please what size chain are you using
D.I.D. 420 NZ3. Stronger than regular 420 or 41.
@@EpsilonZeroKarts thanks man, I'm building a powerwheels converted to proper EV and will have pretty similar power. Wanted to see what people run for chain size.
@@straightouttheshed Sure thing. I have switched controllers a couple of times and have a different motor as well since this video. The kart has a lot more acceleration and the chain is still holding up. I'm considering another motor swap for more torque so maybe there is still hope for breaking the #420.
@@EpsilonZeroKarts sounds awesome man, for my build Im thinking about pairing up electro and co trumoto noisy cricket 375a controller with their qs165 and 60v on 420 chain. Electro has advised me this should be seriously powerful with good low torque
America is nuts, you'd never be allowed on the roan in that here.
Which GPS device are you using to get that frequency of data?
Columbus P-7 Pro
...and now I use a Racebox Mini. WAY BETTER.
Thanks for all the details in the comments.
Hey, I love your channel! Can we get a build list and specs ?
I have key components listed on most of my kart videos. The parts change over time, though, as I try out different configurations.
Very cool , what are you using for a speed controller,putting together a 48 v (4 car battery) and a fixed magnet DC starter motor from a helicopter and don't want to have just a on~off switch ,lol. Any input would be great
faster than my miata lol
are you running any cooling systems
this things 0-60 be faster than my pontiac g5😅🥲
Awesome. Thanks for posting specs
Crazy fast!
Man, I want a tutorial on what you did. 😂 my kids have one and we want to make it faster
Do you happen to remember the diameter of the stock axle? 5/8?
does a 3/4in axle fit without mods? if not, what did you have to do?
Dad projects .... I get it
How are those wheels / tires compared to the stock ones from the kit?
can i buy the axle you replaced?
The farting sound effect caught me so off guard I died laughing lolol
your videos never fail to entertain
Thanks! I'm going to have to get Chris in some more videos.
Nice😂
You had me worried for a minute... 🤣
how do / did the headway 38120HP take the shaking? I want to build a battery pack made with them to be used in a very shaky place... Edit: It's the physical durability i'm concerned about.
Cruising with a buddy is fun but them using the loud gas kart is going to draw way more potentially negative attention
That thang movin 🔥🔥
BTW, What BMS are you running?
Where can you get one that goes at least that fast?
I had to build it. As soon as my newest motor is delivered, it will be quite a bit faster!
@@EpsilonZeroKarts I really want one but i don't know how to build one
@@darkchampion4069 It can be pretty expensive. One with a small engine is a lot cheaper and easier to build, though not as fast.
So jealous you have a path like that nearby. I'd be doing laps on that daily.
I'm waiting for the road construction to finish on some development nearby. I'll have a "track" for a little while.
Are you willing to build one for a client?
Do you build for customers?
Dang those things are fast
Fun too!
What type of battery u r using
How you change the tires? My inner tube went flat.
2:24 was hilarious dude 💀💀
Yeah, your footage was perfect for that. Dean was cracking up all night too.
