  • THEIR are several companies that sell H.O.alternators DENSO POWER BASTARDS MEAN GREEN etc ... that have out puts of over 200 anps @ 650 to 2000 rpm use less than 1 hp per 25 amps made. = RIDE 24/7 These alts R made 4 cop cars taxi etc... They work . you may also note the Tq Converter J.C. Whetney (sp?) made yrs ago . mike peine

  • @perpetualmotion100 I fail to see how I would use an alternator

  • Maybe you were taken it easy cuase dad was there, but that thing is slow. Might have the potential to get to 40hp but I've seen 7hp briggs and stratton go carts accelerate and go faster.

  • Please tell me where you bought the just the frame, i have been looking forever were to get just a frame. i love your idea on your go kart and i want to build my owe. please respawn.

  • I didnt know there were so many engineers wasting time in youtube

  • Nice Video That You Share , So Very Nice Thanks You 40 HP Electric GoKart

  • I Really Like The Video From Your 40 HP Electric GoKart

  • Your Video Is Very Useful Sharing 40 HP Electric GoKart

  • Why use fiberglass seats if you have loads of heavy battery's everwhere, looks very dangerous in a crash. Can also use a asynch motor for more rpm range & torg.

    Ok i admit i'm jeaulous and this is indeed a fine project pure craftmanship!

  • Put those batteries in a box. Apparently, you have never seen one explode or had battery acid in you eyes and on your skin.

  • dose more volts make the battery stronger?

  • After taking that crappy of a video I sure wouldn't show my face on camera. TURN THE MUSIC DOWN SO WE CAN HEAR WHAT THE HELL YOU'RE SAYING!

  • why not use the money to get a good used 25 hp vtwin kohler sideshaft model motor and put it on a homemade frame like i did,now that is badass compared to an electric go kart,i had to put a wheelie bar on it its so fast,or sink the money in a briggs raptor capable of 120 mph running staight methanol on my other homemade off road frame,my go karts are better,this is just useless to me,i get the point of being green and all but go karts are made for fun and racing

  • howdid u make it

  • I think you left the decimal point out of the 40 should be 4.0

  • wait a sec...... "IF" you hit a wall you get Sprayd With Battery acid ???

  • your dad is cool

  • that not a 40hp motor ....... the output shaft look's like it 7/8 or 1 inch ..... it would snap right away ....lol i use to rewind electric motors , i known what im talking about .... that's maybe a 7.5hp ......

  • good luck going through water

  • Wow, that's some great footage... of the ground! Seriously, let's see the kart go!

  • or you could get a 125cc shifter kart 3 times as fast and 10 times cheaper

  • @THEJBUDS this one is 0 emisions, and thats the point of the project, electric accelerates faster and does not brake apart as a gas engine, it also has no clutch and it is 10 times better than 125cc !

  • less talky talky, more riding

  • great project, but please for heaven's sake don't use HP for electric cars, it's bad enough for regular ones^^

  • master link clip on backwards

    

  • THE Pb Batterys cannot deliver 40 HP. why not just go lipo mate. need 30 C battery cells... does not look anything like 40 hp

  • @11trevord - I've always wanted to build an electric car based on a square tube frame and use the Meyers Manx SR body. Great little kart you have. You did a fantastic job.

  • The only thing I would change is strapping the battery's first and then putting the leads on.... my buddy had an electric cart and we strapped a little 2 stroke honda engine and alternator onto it to keep the battery's charged up while we used it.... wouldent run it non stop but it would play catch up when we took breaks or switched riders. Not very quiet or green but it kept the fun going

  • AWSOME, BUT YOUR GONNA GET BATTERY ACID ON YOUR BAG FROM THAT ONE BETWEEN YOUR LEGS.

  • where can I buy a cart frame like you purchasede to build our own? When you mentiioned Cameron carts, do you mean in Hamilton Ontario? or? Thanks and great Job

  • your tire is touching the frame????

  • where did you get the brakes

  • I take it the Final gear is 1.636

  • And actually I don't know if the numbers he was spitting out was mph, doesn't look like 50 in the video. He says 42 and later 50, whatever that's for. Maybe I just wasn't paying attention.

  • tooo damn cool... and I use to race 2stroke back in the day... sprint and enduro...

  • NO SOUL

    

  • @11trevord Very cool vid. Cool gokart. Could you tell me what them two songs were in that video please :-)

    Charliecrazydj

  • Might have to increase the size of the tires.

    I want to say Ez-Go Freedom series golf carts weighing in above 900 lbs would move upwards of 18-20 mph on a 3 hp motor. This being the case, the motor on your cart should be capable of much more.

  • grats, but learn how to hold the freakin camera. my head is dizzy

  • The motor kit he has is a 120v system, but the motor is only rated for 72v, so he has no warranty for the motor. The thing that questions me is why in the world would you use a chain drive instead of a belt. This would be completely silent with a belt drive system, but just sounds stupid with the annoying chain winding. What is the max speed on this thing, because 40 hp should be a shit ton faster than what you were going. Racing karts usually have 20-30 hp gas motors and go 100 mph, why so slow

  • @hitmanskilz Just because it's a 40hp engine, doesn't mean he's going to be getting 40hp. We don't know amperage/wattage. If you watch the video, he outlines they only got to 50mph because they ran out of room, note the skid marks. Also I believe this is just 40hp peak, 12 continuous.

    I don't know about go-karts that much, but I know on scooters high-performance electric engines have a reputation for snapping belts due to the torque.

  • @5PYZ3R That's false, there is belt drives out there that can handle up to 200 hp, used by Orange County Choppers on a lot of there bikes now

  • @hitmanskilz Ah, alright. Well like I said I'm basing on goped experience with what I said about belts. Maybe the people I was reading didn't know what they were doing, I found out later after posting my comment that you would typically get a thicker belt just as you would chain numbers.

  • @5PYZ3R and actually these motors are very powerful, on the home page of evdrives.com a guy in sweden used the same motor in his compact car and gets a top speed of 70 mph 67 ft lbs of torque with this electric motor is equivalent a very large street bike engine

  • Lead-Acid batteries have a large capacity, but are really heavy. I built one this past summer that weighed 53 lbs and ran off of airplane lipos. A123's LiFePO4 batteries are nice too if you want to avoid fiery death at all costs. If you're still working on this, go for weight reduction. Great job anyway!

  • Is sure 40hp? very slow for 40hp....

  • @Luca77azmodelnet :O do you guest the HP´s just for the speed on a TEST in a neighbourhood?

  • @Luca77azmodelnet it might be a 40 hp but he doesnt have enough power going to the motor for it to be used completely if you know what im trying to say

  • @Luca77azmodelnet 40 HP is the model name or the max health of the gokart rofl

  • @mapukmapuk LOL

    

  • @Luca77azmodelnet its probably quite heavy. batteries weigh a ton

  • This is why the USA will lead the world. It is called innovation.

    Do you export to Australia? I can't be bothered building myself, and the Australian Dollar is strong enough. If you can't find a job build one. P.S Use Lithium Batteries

  • How was the stability at 40 MPH? Was the thing wiggling all over the place?

  • thats a sick cart you got there man i would love to own that or something like that

  • you realize that you run a serious risk of electrocuting yourself while driving

    that thing with all those exposed wires and connectors, rite?

  • MONGO!

  • "Better than the Joneses" environment here.

  • nice work but you better get the batteries inclosed if one decides to blow it might be your last ride fyi look up battery acid burns

  • Too much noise hard to hear anything...

  • the motor is AC or DC! who many HP? is urgent please

  • wow I can't even get my dad to call me!

  • Great build!

  • Great video, minus the horrible screamers in the background.  Do you have a copy sans the music?

  • not bad

  • STOP OVERDOING IT WAIT ITS AWESOME

  • thats a camera with no stabalization

  • hey whhere did you get that motor?!?!? i want to design a man carrying tricopter

  • WOW LOOKS SLOW...  LOOKS LIKE A GOOD BUILD BUT SLOW AS HELL.

  • @hopcup1 40hp on a kart wont be slow at all, Guarantee its faster than most karts

  • check out the 70,000 watt go cart. you should do that man.

  • @K2Jennerator cause it rapes yours

  • /watch?v=3UOToi0fHNs&NR=1

  • haha,proud dad :)

    Nice kart.

  • by doing things like picking an efficient motor/motors that has more torque per amp reducing weight improving aerodynamics changing gear ratios etc etc

  • @anewlow23 that is true, I would continue if I had funding but I am trying to get funding at college so I wanted to think on a larger scale that would draw attention to it and make it appeal to professors/funders

  • @11trevord how much are these go karts without all the mods on them? and what are they called?

  • Respond to this video... If I had the money, I would deliver an electric sprint kart, but since I don't I can only wait for a way to get the funding to upgrade to the lithium batteries, and AC motor I have mocked up in some designs

  • Sorry for my noob question, but it isn't A/C, is it? And where did you get the motor?

  • @lofams no its not, it is a DC current from the batteries, and a DC motor AC motors are much different and far more expensive

  • @11trevord and where did you get the motor?

  • @lofams Cloud Electric

  • Respond to this video... If ur interested I can sell you mine

  • @11trevord Very cool, Is that Lee High school in Jax, Fl?

  • @11trevord an ac motor is useless for this application anyway

  • You built an electric go kart and you only have one video? More videos please . Nevereverthesame 's go kart did 40 at 72 volts . Does yours spin the tires?

  • @anewlow23 no, it doesn't spin out, all those guys who spin there tires have no clue how to utilize their microcontroller to control the amperage output to their motor, unfortunately I have stripped this frame however I am starting on a superkart project that would be much more applicable to the industry since it mimics road driving conditions, not sprint conditions

  • @11trevord Applicable to the industry? What industry? I thought electric go karts were mainly for fun on a track not road driving conditions since your not allowed to be on the road with them. If you want industry build an electric car. It just seems like it would go faster at 120 volts you should have done more videos with every possible programming configuration besides doing burn outs and donuts is fun why do you think you have slicks! Mine went about this fast at 48 volts with a seriesmotor

  • @anewlow23 applicable to the race industry, electric motors and batteries themselves could never stand up to sprint racing, have u ever driven a gas kart on a track? The tight corners and hard acceleration would drain the batteries at an incredible rate, believe me, I have run the kart on a track. Additionally it provides a platform that can be applied to better understand what commuter electric cars would need to extend their range

  • @11trevord Well your motorcycle starting batteries are not deep discharge so how do you know from your experience with them during the testing of this kart that electric motors can batteries couldn't stand up to a track. Believe me its already understood what improves range its called more batteries or to be more specific better battery chemistry which is done in labs not on the track. Go karts are for racing and trying to improve your performance cont..

  • how much does it weigh?

  • @breezy785 it weighs in at around 320 pounds

  • @11trevord wow holy crap. acceleration?

  • what is the engine? and how much was it?

  • @pvtmeives i have mine laying around since I ended the project on that frame, I can sell it to you for 800, online I have seen it for a grand. The engine is a sepex (separately exited motor) commonly found in golf carts, this particular model is made by D&D

  • got batteries?

  • @jimmehjimm I do, are you looking to buy?

  • looks like a frigging super speed bomb

  • wow 40HP!!!!

    

  • nice close up sit shot

  • how long can it run on 1 charge??

  • This would be much nicer with LiFeP04 setup, once you go to lithium, you will never want to go back

  • @cleanairaus thats what I am currently in the midst of

  • My GAS kart has 45hp and it is a lot faster than that it is not 40hp

  • @11trevord how much did it cost to make

  • how fast? :3

  • I'm curious where would we find that micro-switch? or what would the appropriate title for it be? how much did you shell out for the motor?

  • swap the brake disc with the rear sprocket, position the motor centrally behind the seat, centralize the seat and put more batteries on the right and get some LiPo's gaaadammit.

    and your chain circlip is on backwards.

  • Hi, can you share the link of the motors manufacturer and the datasheet? Thanks!

  • Master link on backwards

  • could you send me what the parts are used, im going to build the same one (i got the same frame) and want to easy-build with a time sheme. Ill post everything on my blog!

  • The go cart would beat the smart car

    

  • @lukeyj15 yes, by a mile

  • i imagine the acceleration would be very linear, compared to say a Yamaha KT100S??

  • @fixitdude74 yeah very much so, I have a parilla leapord and a honda cr125 as well and i can definitely say the elctric kart has a linear power band

  • yay. 5 minutes watching the ground and simulated earthquakes.

  • rich

  • nice kart! i am amazed it cost $10000. can you put a parts/price list up? wondering about the frame too. Also, not sure if Corey read it somewhere or was running mouth.. how long does it run on a charge? I am thinking about opening an indoor electric go kart track and even found nice carts, but they cost about $5000. if i open a track i figure i would need at least 10 to 15 cars and have extra batteries charging to switch out.

  • @thomaspmcguire I will look for my old documents, but if you want something that runs at a good race speed of like 50-60 mph, batteries, frames and what not will be insanely expensive. I

  • urgh so many imperial measurements!! nice build tho man check out lynch motors for the worlds best electric motors

  • i wish everybody that had the brains for building this great innovation tech had the mean to do it. i feel so limited in my small school and with my limited resources how can i ever get seen by the colleges! just gotta work really hard in pltw

  • @stampede1027 thats a great attituted, if you are driven, then you can accomplish anything

  • @Corey497 it was a learning experience about gokarts and engineering, also, not many can boast an accomplishment like this their freshman year in high school, besides, Purdue seemed to like it enough to accept me into their college and provide a scholarship

  • @11trevord Congratulations on the scholarship, mechanical or electrical engineering?

  • how much did it cost???

    plz some one make me one and ill pay u

  • @t4b15h it is a $10,000 investment and it takes months to build

  • what website or retail store did u get that beast motor from

  • @TheModificatioNation I found it online, search for D&D Sepex Motors, they usually run for 700 dollars or so.

  • wondering in the vid at 4:19 it looks as if the chain is resting on the plate is that how it is or is that just an illusion ??

  • how much did all of this cost

  • @CCSinventions no, his dad is rich, hes one of those punks that wont fund his own hopes and wishes, always turn back to daddy and his money, wont work for what you want good for nothings i call them.

  • @miketheredneckable It must be nice :/

  • Comment removed

  • 4: bolting battery trays to nerf bars is a no-no. Simply pinning the nerf bars on both ends, or running them loose can change cornering performance from great handling to binding up with the potential to lift the tire 12" off the track..

    Really a fantastic job and decent result, but you need to do some more homework and address many issues before it will be a practical machine for the market. Keep up the good work, sorry to burden you with the facts, but even unmentioned, they remain.

  • @thewayitisnt this is merely a prototype, and I have run over 100 laps in it with no problem on a true kart course

  • @11trevord slick good job nice work

  • which one of you is the electrical engineer or did you find plans?

  • there are so many deficiencies and things that are done wrong that a basic builder would do by mistake, but your project is all about learning!!! good job

  • @manuelbou finally a semi nice coment lol... any suggestions?

  • Hello =D

  • how long does it take to charge? max speed?

  • @lepardgecko120 it takes eight hours to charge, and its top speed is around 72 mph

  • gay way of using a 40hp motor, stupid batteries! get 4 deep cycle batteries.

  • @alexreuk no, the gay way of using the 40hp motor is shoving it up your butt and turning it on.... i agree with you on the batteries though.

  • @alexreuk how else would u use the motor?? what batteries do u reccomend?

  • word of advice.. clean up the wireing and use heatshrink...

  • how much were the tires i need some

  • how much was the motor?

  • Where do you get those tires

  • @iceman23332 they are standard race kart tires, I am lucky to live 2 minutes away from a go kart specialty store, Cambrian GoKarts

  • @67spudgun its a 2007 Birel 125cc Shifter Kart Chassis that i stripped down to put all the electronics on

  • @11trevord new that reading books about electronics but its not very nice getting a that kind of volt going thru your body

  • what rpm does the motor spin. if it spins half of what a two stroke does say 8000 rpms then your gearing is WAY too low. considering the motor turning 8000 max and your gearing of 1.63 your top speed would be 160 mph. way to high. i think that you should gear it higher like more the range of 3-3.5 but i dont know what these motors spin but i thought that they were around 8 grand.

  • @brunnemerc Since he said high torque motor that usually means low rpm. Probably around 3000 rpm.

  • @brunnemerc why is 160 too high.

  • watz crubs?

  • awesome job man

  • Sick, pretty good speed. Make sure to watch out for those curbs, I know this kid that had an electric go-kart and totaled it on a curb right in front of my very eyes...

  • @wilcofan14 I know him too.....
