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.

[@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

[@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

[@seansysig]

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

[@markwashington2412]

Next project

[@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.

[@addicted2fuel245]

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

[@CarsandCameras]

Thanks man!

[@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.

[@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!

[@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.

[@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

[@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 :)

[@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.

[@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.

[@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

[@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!!! \(^_^)/

[@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!

[@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....

[@dbman992]

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

[@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! 👍🏼👍🏼👍🏼👍🏼👍🏼

[@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.

[@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

[@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.

[@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

[@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.

[@michaelvangundy226]

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

[@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!

[@Joe0898]

This kart is just mental

[@ghomerhust]

great scott!

[@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.

[@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

[@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.

Send the address and times y'all are at work to also is there a trailer in the property ?

[@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.

[@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]

[@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

[@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

[@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/

[@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.

[@akkudakkupl]

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

That was so cool !

[@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.

[@rokkstar115]

nice drift into the driveway at 06:55 john!

[@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.

[@guy_incognito7538]

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

[@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.?

2 things. 1.Water (even just a little) = friction. 2. Lubricity in ANY moving parts. Best light lubricating oil you can get. Ok I lied... 3 things. 3. Maybe consider a "nose" to make it a bit more aerodynamic.

[@patthesoundguy]

Ike! You are one brave dude! Glad you didn't die 😉 That was Faaaaasssst!

[@holtpage8226]

One thing that will help with it being twitchy on bumps is adjusting the kingpin inclination. A line drawn from the top of the kingpin through the bottom should intersect the ground close to the middle of the tire contact patch. Typically go karts don’t do this. When not set correctly it can create a situation where bumps can push the tire, allowing it to pivot on the kingpin, causing the kart to pull to one side or the other.

[@BigD1395]

Awesome runs brothers!

[@jamescole6846]

I was just about to say it but someone already did. You need a Tach. With that you would be able to see what your RPM's were at 70 and then do the brain math and extrapolate from the size of your gears and the circumference of your tires, the exact gearing ratio needed to change to get to 88 or faster.... As close as your are it's not going to take much. I would put back in the slightly larger engine drive gear on the clutch. You only have 14 miles to go. Also, The sticker on the floor-pan to keep the paint from getting all scratched up works for now but you should cut a piece of aluminum diamond plate to stick up there about the same size as the sticker with a few pop rivets to hold it in place. I did on mine for the same reason and it looks great , BTW, you can cut aluminum diamond plate with a carbide tip skill saw. I used a 18V on mine 1/4 inch thick. The blade will most likely will not cut wood very decent anymore but it leaves and nice clean cut on the aluminum. Change the blade afterwards and keep the metal one for next time.

[@MrArmydad0621]

Living is definitely a win. Badassery gentlemen.

[@mealex303]

Get a large plug and a foot of chunky cable and have it dragging from the back somewhere. LOL a tv aerial on top and two smoke machines aiming at rear tyres for cool effects on takeoff and high speeds

[@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.

[@johnelledge6685]

Not gonna lie, much respect even at that speed!

[@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.

[@breezysbikeshop7220]

Would it be better to put the tie rods on each side of steering wheel block? It seams to me both on one side would cause come play. ty for considering that change.

[@Acoustic_Theory]

Are there narrower tires that you could use? That would lower rolling resistance, and you don't need cornering or handling.

[@ShaneMatthews27]

my go kart frame that looks like one of those old was mart special frames drives totally smooth at 50 mph and is very controllable. the rear tires sit up some from when I welded on a live axle kit so it has some rake forward, I wonder if that has anything to do with it?

[@ghomerhust]

a slight rake will help with keeping the wheels straight on a smooth surface, but when turning, or when on bumps, it can get darty

[@rayditzenberger9517]

A forward rake will actually decrease caster an make it more darty

[@franksantarcangelo1950]

Oh boy you guys are so cool I wish I had neighbors like you😁👍🏻
