20HP 212cc Top Speed Run | Delorean Go Kart Build

[@tacocat8884]

73.9mph on a predator powered yard kart. That's INSANE guys!!!! Keep up the awesome builds!

[@ThriftStoreHacker]

You know things are getting serious when Ike puts on safety gear.

[@seansysig]

Crazy 70+ mph on those tires you could easily hydroplane.

[@markwashington2412]

Next project

[@markhall3434]

Love this project! As someone who used to love to throw Rods in $10 yardsale 5HP Flat Head B+S engines.. they didn't last long, but had another block in the wings to swap parts onto. As they loosened up, they make even more power. IMO, your 20HP isn't winding high enough. Have you checked Engine RPM? In my experience: If it sounds like it's going to explode, you're close to max power. Just my two cents from hacking flat head 5HP's w/o ANY aftermarket parts. My Recipe: Big Lawn Tractor Carb + homemade conduit intake manifold, HOG ports way OUT, Footlong homemade exhaust pipe, Give flat head a fire channel from cylinder to intake port, Thin homemade copper head gasket, belt sand the head, two Exhaust Valve Springs (much stiffer than intake), Springs shimmed close to solid at full lift, Grind off back side of cam maybe 0.1", make backside round till the ramps, Weld a "Bump" on the lifters and Grind off for proper valve clearance. Homemade Offset Keyway to advance ignition timing.. Total HACK JOB (Loved it!), but results were astounding.. If the block didn't have a puddle underneath, there was more RPMs/power left. Rod always failed, usually sticking out the side of the block, with piston pin pulled out the bottom of the piston, and a pile of metal pieces in the crankcase..

[@markhall3434]

another trick was to squirt some oil on the centrifugal clutch to raise the engagement RPM.. had a worn out Yardsale OLD mid 60's Margay cart (Simple!) with a McCulloch 100cc that I could NEVER get to run, so switched to B&S..

[@markhall3434]

instead of Patreon, Can I just paypal you guys a few bucks? To what email address should I send?

[@CarsandCameras]

This engine on a more aerodynamic frame would definitely be faster... Do you guys remember that lay-down kart we picked up in Virginia a few years ago?

[@andrelafond7474]

CarsandCameras yes i do, that would be awesome, also, quick tip, if you lean down in the kart it’ll be more aerodynamic, all of the kart racers do it.

[@JohnWheels]

CarsandCameras, I remember, ya’ll should swap the motor over

[@robertgabelucio6647]

CarsandCameras please bring back the black widow!!!!!

[@ashleylong4272]

yea but if you made the videos longer i would enjoy it more i love this channel ive been watching for about 3 yers not great channel keep up the goodwork guys

[@bigbellyracing2527]

Sounds like someone is jealous dont be a hater lol

[@rejjohnson2004]

Thanks again guys for another great upload 42 years old here and I get giddy as hell when you guys put out a new video keep up the great work your guys's videos Rock

[@bob8085]

Everyone's saying you need to build a 2 stroke build, i agree take that dirtbike engine and fab it on a cart

[@eclipsegaming5998]

your not talking about that old kawasaki they got running earlier on...

[@bob8085]

Eclipse Gaming Yeah I am, pretty sure it just sits

[@frankozunic3229]

I would like to see them make a 2 stroke mini bike

[@koreywilliams4570]

I found a turbo vw bug engine online for a reasonable price and I thought about tossing one on a gokart. Vw bugs are pretty small to begin with so the engine and trans should fit.

[@Gone_rn]

Two strokes are unreliable

[@upsidedowndog1256]

Nice chassis tuning! The clutch never sounded like it locked up. Steering "damper" is needed, to dampen is to wetten. Nice job guys!

[@ctpctp]

Came here to say the same. Steering damper would do you soooo much good on there.

[@ctpctp]

Also remember that all the play in any front end parts, all added together, will add up to toe out if your toe in isn't sufficient.

[@ExperimentalFun]

Yes, Please do the back to the future sketch, make sure you have the flaming tire marks and everything, You can use some of Ike's old cars and get some of your friend to dress up, It would be hilarious :)

[@addicted2fuel]

The kart is awesome. I really like the sound of the engine. Can't wait for the next video

[@CarsandCameras]

Thanks man!

[@joetri1970]

Y'all are time masters you keep me entertained 10 or 15 minutes once or twice a week.

[@CarsandCameras]

Thanks!

[@leebraddock9789]

We were always told you wanted the front wider than the back, it always worked for us! Raced go carts for 8 years

[@MRT_H]

Let's see more on the drag rail!!!!

[@DeliciousDeBlair]

AMEN!!! \(^_^)/

[@CarsandCameras]

Video next week!

[@MRT_H]

CarsandCameras 😁😁😁👍👍👍 thanks! Also, this video was pretty sweet too....

[@DeliciousDeBlair]

YAAAYYY!!! \(^_^)/

[@billcohnen6326]

Now that the 750cc cross kart is running properly, install a 3 point harness, taller weels/ tires, and drive it on the mining roads in Colorado, that would scary fun, and also show off how awesome the CK is.

[@Splungers]

The springs on the spindles are your last twitch. The movement steers each side on hitting the bumps, the tie rods travel in an arc, toeing either side in or out independently.

[@bobcatfiveoint0cj7]

I was thinking the same thing its getting bump steer , either shim them tighter or replace the springs with some homemade spacers.

[@kevinhorning3624]

you guys are having the kind of fun i had in the very early 70,s. built a shifter kart outta a rupp kart with a 125cc yamaha 6sp bike engine. almost died on that one. dad should not have bought me a new stick welder lol guys. kevin in pa.

[@kellytaylor3915]

Nice job guys. This is a really nice kart setup. Makes you wonder what an extreme 420 single could do. We are looking forward to what is next! 👍🏼👍🏼👍🏼👍🏼👍🏼

[@armancha23]

I just purchased an old Manco dominator with 5.0 subaru motor. I ordered the performance carb, double seat and am stoked to start the project with My 10 yo son. THANX for the CC10 Discount! I have been watching all of your videos for the past few months and feel confident to make some monsters haha.

[@edwardwerick2420]

Was thinking of the enduro (lay-down) kart chassis you guys picked up in Virginia a while back when I was watching you test the Lifan powered shifter kart. I'd like to suggest you extend the rear of that chassis and mount the engine as low as possible in the center of the frame. This would reduce your frontal area as much as possible. This was the idea behind the Enduro kart set up and it was effective. Lengthening the wheelbase would also make the kart More stable at high speed. When I was racing I had the thrill of racing at the Watkins Glen road course in New York. I was running a Maculloch MC 93 in a sit-up kart. My best speed was 92MPH. The 2 stroke engine topped out at 12,500rpm and my gearing was 12/64 with 35 roller chain. You do the math. The top class at the event was B & C open and the winner was an Enduro Kart with dual 125cc engines on alcohol. He was clocked at 135MPH and was lapping the 3.2 Mile course 30 seconds slower than the track record for all classes including Formula One. Too bad he didn't have a flux capacitor! Great Scott!

[@akkudakkupl]

It's best to use prime number teethed sprockets - longer chain life - links hit the same sprocket tooths way less often.

[@hugofreak9990]

Can’t believe a predator could go up to 74mph

[@ghomerhust]

there's kits that push that engine upwards of 30hp, all from a tiny 212. but, the mods put the engine up to similar levels of engineering that you'd find in something like a lambo v10, lots of HP per liter

[@michaelrodgers6559]

It's barely a predator any more

[@vito_pito1o175]

Michael Rodgers true 😂

[@michaelangelod5008]

Yeah but its such a waste of money heavily upgrading a 212cc because gopowersports is such a rip off and of they had too pay out of pocket all the mods together would be $1000 because each stage kit is like $300 a piece on go powersports because they are a rip off and that is outrageous for a chines engine plus you could get a low cc manual engine and easily make it go that fast for less than half of the money in predator

[@electricdeckhead3083]

probably didn't relying on a speed app.

[@TC-zi2yp]

Man I love how you don't over use the jump cuts while editing. Awesome videos!!

[@michaelvangundy226]

You guys are doing great! A lot of improvement. The sound and video quality is getting fantastic. Drone time?

[@wonemorethought8009]

Ike sounds like king of the hill. "Dam it Bobby". Another sub, keep up the shenanigan's.

[@keithlester9152]

Did some math, with 11 inch tall tires you need a gear ratio of 2.975 @ 8000 rpm to go 88mph. 3.161 @ 8500 3.347@9000 rpm

[@dbman992]

More tension in this top speed run than the end of infinity war!

[@elijahbabcock6609]

Buy a wig like doc browns crazy hair to wear during a dramatic ride with some back to the future original sound track playing in the back!!! That would be great.

[@anthonywitz2924]

You guys didn't seem to thrilled about the top speed. Yeah it's not 88mph but 70+mph is still a great achievement. All from a little 212 predator. Hats off to you guys. The things you accomplish with go carts is amazing.

[@isaacitllbefine7231]

Anthony Witz lol. Thanks

[@Joe0898]

This kart is just mental

[@ghomerhust]

great scott!

[@weetzerswoodshop]

Make sure to connect a plastic flag pole (painted silver) to the back of the seat to make it look like the hook that grabbed the electrical line to get back to the future! You guys are great and I enjoy the hard work you put into making these videos!!! Keep up the great work!

[@CrazyIvan1337]

"Well then why are you doing it?" [It'll be fiiiiine!] Missed opportunity, lol

[@azhunt0996]

I'd put this motor on the 200cc shifter frame, jet it for methanol and see what you got. Better handling at higher speeds and a faster cooler running motor. It's what we ran in our Briggs race motors. Great videos!

[@mrmadmike427]

Great video guys !’ Needs the iconic box vents (exhaust) or whatever those square thingies in the back are lol

[@bobcranberries5853]

I think it’s ready for some aerodynamics! I think Ike is kinda tall so his chest Square footage would be like ? What? 4 or 5 sq ft thats a lot to over come at 70. Try putting a text book out the window of a car at that speed! It’s approximately one square ft.

[@mopardude6969]

70 MPH is pretty damn fast on a go-kart. You guys have a winner far as im concerned.

[@isaacitllbefine7231]

[@addictedtoshinyhunting5447]

Your my favorite KZbinr

[@allenmckinney9533]

GREAT SCOTT! you can't forget the frizzy white wig.

[@natevanbynen6595]

Again a tiny tack (knock-off) $20, will let you know engine RPMs. no guessing needed or relying on listening to taped audio.

[@ClumsyCars]

Nate Van Bynen could use a knock off Arduino with Bluetooth module, $10, and have speed and rpm on the phone

[@AntonBabiy]

Nate Van Bynen yeah... And where is that tach going to get its signal and power?

[@natevanbynen6595]

super simple, Tiny Tach has 2 wires; 1 is grounded to the engine and the other wraps around the spark plug wire (for the signal). and that is it. The tach itself has a build in battery that is good for 3-5yrs. bad part is built in battery cannot be replaced, you have to replace the whole meter. Also this will work on multi-cylinder applications. I have one thats been going for 4 years and still kicking strong :-)

[@chillwill3109]

Nate Van Bynen mine cost 10 bucks off of eBay

[@AntonBabiy]

Nate Van Bynen k my bad. I though those things needed 12v power

[@natparker4845]

Love the high speed runs guys. Some comments are saying to get a rev gauge. I think that’s a good way to gear it correctly for max power. Also love “back to the future” and if you were to do a skit that would be funny as hell. Some more stainless steel panels (for aerodynamics) and to look more authentic

[@NckGarage]

A few things. Do you think putting gussets to the tubing going to the spindles would strengthen that part of the cart and remove some bump steer? Is there a way you could run smaller tires because if so you cut down on wind resistance rolling resistance and inertia the smaller the better. You could also air up the front tires more and last thing you could get a cheap teach and not guess on engine rpm. By smaller I was referring to width not really height but you could change height and then change gear sizes to compensate with the tire height being smaller which would also help with wind resistance

[@jasonleedham5678]

Surely air DOWN the tyres? hard tyres bounce more, air down and they will add a little suspension to the ride. I would drop 10psi, then try it, and add 2 psi at a time, if it needs more at least they will know

[@NckGarage]

Jason Leedham with the tires aired down it would grip the road more which would cause more drag with the roads if they air up it would cause the contact patch with the road to decrease the amount of energy to push the go kart especially at higher speeds especially with the front tires because they aren't meant to put power to the road

[@jasonleedham5678]

N1ck0145 Garage I was thinking air down to combat the twitchiness, I see airing up would decrease rolling resistance, and help the kart go faster, I was thinking of safer handling....

[@rokkstar115]

nice drift into the driveway at 06:55 john!

[@madtexauto415]

Am I the only one who instinctively looks away every time they weld

[@Ieatpeople2]

I flinch every time lol, its hard to watch

[@MedFireSL]

A burn of the eyes one time and you’ll never look at welding without a shield. Live or on video. I won’t.

[@yt0097]

For some reason I feel like my eyes are actually hurting while looking at it in the video, then again my monitor is ridiculously bright even on it's lowest setting (an displaying "white" just "bleeds" the back light through on a LCD).

[@theschwartz5260]

I definitely looked away each time...force of habit

[@DoRC]

Thats some pretty funky steering geometry...

[@augustsawzak5401]

That thing probably hits 88 mph faster than a real delorean 😉. Those things were really underpowered.

[@BuzzLOLOL]

Deloreans do 130 MPH...

[@danielmariscal3934]

BuzzLOLOL doubt it tbh

[@BigD1395]

Awesome runs brothers!

[@gokarting1018]

Mr fusion gas tank!!!

[@SportbikerNZ]

Awesome that Isaac did the speed run. Good job man.

[@waderedsox]

MORE TOE IN, a steering damper is a bandaid, a couple ticks between the front and the back at 18 inches is NOTHING

[@ImTheJoker4u]

Toe in brings the fronts of the tires closer, which makes it More responsive in corners, but twitchy on straights. Toe out has the opposite effect. Straight line stability in increased, but cornering grip will diminish.

[@BenHaskell]

John Ulicky pretty sure that's the other way around... Toe in for straight line stability, toe out for cornering

[@nicovanduin1553]

it's the other way around

[@frigglebiscuit7484]

john ulicky is right.

[@BenHaskell]

Just to put this to bed, have a read of this - toe in improves straight line stability, toe out improves cornering en.intraxracing.nl/techniek/camber,-caster,-toe-intoe-out/

Not sure they make superchargers for small engines, and I'm not entirely convinced it would be effective either.

[@DonovanBryant92]

[@g-man8008]

Put a rack and pinion steering on it. That might help. Also put a dampener on it.

[@brokecountry3965]

Great attempt guys!

[@colemanchapman8725]

Put the turbocharged 420 on something else other than the drift trike.

[@kerryhuston3669]

I think the bigger sprocket back on the engine, and leave the smaller rear sprocket. It did really Flux Cappasited anyway. Balls man balls. Thanks for the show.

[@hotwheelsdudereviews1370]

That was so cool !

[@rejracer]

Fellas, I think it needs bump steer spacers, get the tie rod ends on the wheel side close to level with the steering shaft end. The frame flex can change the geometry. If it steers away from the bump hit, then this may be something to investigate.

[@josepherickson7618]

[@noobsquad2652]

You did actually very well for a DeLorean because those adult couldn't get up to 88mph in the movie they had to edit the speedometer to 88mph so well done

[@isaacitllbefine7231]

Noobsquad2 lol

[@psygn0sis]

Adjusting the toe would have been faster, easier, and more effective at eliminating the frontend from darting. A car with excessive toe-out will have skittish steering, often darting to either side of the road very easily. The usual spec is slight toe-in to compensate for angular pressure that forces each tire outward as the car rolls down the road. 2mm over, what, 3 1/2 FEET (length of your measuring pipe).... is too little! You need more toe!

[@RV-jw7nb]

Was looking for this comment.

[@jacobparker4587]

One small, albeit important step, make sure the driver is sitting in the kart while you align it! At least with racing karts, they'll flex and alignment specs become dependent on weight distribution. With a European kart, it is not uncommon for karts to gain a few degrees of negative camber just from the driver getting the in the seat. Cheers, Boys!

[@sarahthibodeau6439]

First after that guy

[@Orbacron]

[@graememcleod1751]

it needs nos that will get you to 88 mph

[@tct72]

That's what I was thinking and it would be way easier then a turbo setup.

[@murphragous]

Can it be a different brand of nitrous oxide, or does it have to be N.O.S.?

[@sheldon6964]

I'd love to see you make a stainless finished sheet metal ferring on the front end of the gokart, I feel it would complete the look nicely and maybe get you the drag reduction you need for a larger rear gear, great video guys!

[@johnnotriddle7970]

51st comment

[@pathaze4299]

After changing the gear ratio, try adding a little sheet metal shroud that covers the drivers legs and the steering wheel to make it slightly more aerodynamic. Then you could even shape that shroud to make the front end look like a DeLorean with square headlights.

[@rager522]

Nice job guys!

[@MrArmydad0621]

Living is definitely a win. Badassery gentlemen.

[@TheRSGarage]

Ike is utter madness. I don't know how he fits those cajones in that leather!?

[@johntingle455]

You did add positive caster angle, which will result in the wheels straightening out after a turn. The main adjustment that would stablize the kart in the turn itself is being sure the Akerman angle is correct. Correct Tow in or out is desireable, along with scrub radius. This will prevent the steering tires from fighting one another in the turn and causing one or both tires sliding sideways and wearing them out prematurely. Each tire will turn in it's own correct radius...much like the shopping cart front wheels do. However the individual radius angle of the shopping cart wheels is determined by the friction of the surface you are rolling the cart on. This will not be the case on your cart because their angle will be determined by the "set adjustment" of the steering linkage.

[@jarekmace1536]

Ever thought about a belly-down position? Feet against the rear bumper, engine between knees, and lying over the steering system? Longer but much more streamlined.

[@guy_incognito7538]

Yea but if you hit something, you are goin in face first rather than feet first.

[@UnTamedMustang]

NICE! Very nice. The 70+ mph club.

[@alien200049655]

Don't forget the Cyan colored Electroluminescent wire That turns on when you hit 88 Mph. Also flame trails behind the tires would be cool too, if a bit dangerous. But it'll be fine.

[@austinlane5533]

15:40 "ayy dude you gotta come back.." I thought he was talking to the chicken chillin in the driveway..

[@stevebarnette]

That steering looked very reminiscent of Senna’s steering shaft; the one that theoretically broke at high speed and killed him. Glad you found that play and addressed it.

[@ChristopherHayniedd980]

Guys I was a welder for over 25 years. When welding with a mig vertical start at the bottom and spot weld it up to we're it looks like a vertical bead. Going down you are not getting the penatration you need. Just a tip.

[@dustinshort6207]

Your bump steer is from the (spring) spindles. As they move up they become closer together. If you hit a bump on the right tire that tire steers left, if you hit a bump on the left tire, it steers right.

[@Almightyrastus]

The big defining look of the Back to the Future car was the large rear vents

[@justjackfromsc]

Cool video. I still think you need a wider tire up front or at least take a little bit of air out of them. Thanks for the video guys.

[@vintagespeed]

20 degrees caster...!! i think you have introduced "chopper flop" into the front end on that go cart... keep it up!

[@gr8hairy1]

A ROLL CAGE that opens to get in and out styled like DELORIAN DOORS! That's one of the first things people think of with anything Delorean "style"

[@FordGTmaniac]

Smog pump supercharger is the way to go, the aggressive gearing won't be a problem then. There's a VW/Porsche model that's very popular because the outlet is 24mm, so it matches perfectly with the 24mm intake on the Mikuni.

[@franksantarcangelo1950]
