THE DRAGSTER DOES (BABY) WHEELIES! | 50HP 670cc Drag Rail Kart
Вставка
- Опубліковано 17 жов 2024
- Our vintage Predator 670cc V twin drag rail has been down for over a month because of defective magnets in the billet aluminum flywheel, causing weak spark. Today, we install new magnets and test our new 780 torque converter weights. With the new weights, the dragster launches hard enough to do a small wheelie!

2:26 smoothest transition ever
2:11 was awesome too
@@FastLaneLyfe *2:07
I'm an oldtimer(68) living vicariously through the two of you .Please keep it up.
I loved the editing at 2 minutes 15 seconds where you're going to take the fuel tank off of the other Dragster and as soon as you open the door boom there he's sitting great editing that was
@2:15
Johnny V baby it’s more like 2:07
The sound on this is so amazing 😍 idles like a Harley Davidson haha
“Get me something to drink dude”
*opens refrigerator*
*man with solo cup appears*
“Ahh delicious”
Oh that was so good
Speedskid The cooooolest!!!
These guys got me back into Mini Bikes, we have bought two of them, a Coleman and a Trailmaster. We are going to have lots of fun with them up on our Ranch. What is wonderful about Cars & Cameras is not just the informative videos but watching the genuine friendship between these two young men as they build various projects. It is also heartwarming to know that John's parents support their son's hobby. John's parents obviously love and spoil him, look what they let him to to the garage and property with his projects. The neighbors must be pretty understanding as well. This is a great American story about a wonderful friendship of two mechanically minded young men.
Man, who else waits for these videos to come?
I know i do
Max leonard every week !!!
Your editing skills are on point
Watching that clip of Ike pulling away from the camera, it looks like the left rear wheel was moving from side to side on The axel. Love this build!
It's gonna run great with a new carb. Can't wait to see the time slips.
Ive been following your channel for years, Ive gotta say, these last few months have been your best! The content is great as always, but I really like the extra time youre spending editing the videos, all of the cut ins and such. Im still laughing at the fridge door lol!!
I love all the 70 s in the back ground, brings back a lot of memories, who’s grass are you tearing up,lollollol wow nice place, kool guys thanks BigAl California.
I think fuel slosh may be a part of your problem. Since the carb is sideways like the whole engine, you nail it and all the fuel sloshes to the back of the bowl during acceleration. That may be enough to cause a lean running front cylinder or even a misfire. Whatever new carb you get, I would suggest taking it apart and seeing where the main jets get fed from and put that toward the rear of the rail so when you nail it, it’s always got fuel.
Gotta love that 60s Slingshot Dragster look! You guys know how to have fun!
the transitions in this video are so good. Nice work on the editing
Thanks I needed that the dragster racing in the grass (Issac doing a good job to keep it under control) was GREAT! Thanks Guys!
How can such a small engine sound so mad!! Love it!
removing that "barrier" will make it (essentially) a single-plane intake, so in theory it should also make torque at a higher rpm....but then that's why experimenting is so much fun...
Sounds like the chain is skipping...you can hear it and see it at 13:22 .Looks like the shafts are deflecting also..
harry guy I too noticed the movement/"slop" of the back wheels on takeoff. Wonder if its shafts or those wheels deflecting?
Yeah, and I've always wondered why you don't use a spring loaded tensioner on your chains???
I noticed that too on the last run, that rear shaft looked really sloppy.
Yes both the left and right side of the axle is bending toeing both the rear wheels forward 13:19 when he hits the throttle and it looks like the chain skip might be caused due to the axle flexing cause as the axle bends forward it takes tension off the drive chain just enough to skip by the looks of it.
You can see the final drive chain to the axle get real loose on take off 13:34 ...you can see the left tire wobble back and forth when the chain skips 13:22 use the slow mo function and you can really see it good.
Thicker axle might be in order...
Neil MacPherson
Haha I just about pooped myself.
You have my uncles name , spelled correctly and everything.
Good to see another Mac!!
got a lot of rear axle flex , that beast is twisting the rear tires too !!!
What I’m thinking is the g forces from the launch is pushing all the full to one side of the dual bowl and only feeding one pick up
thats what I was thinking also since its not a high G application Engine to begin with , we have slosh control plates or stuffing in hard launching car carbs and jet extension tubes to prevent it from leaning out , also the cutting of the spacer will make the carb look bigger to the engine since its now pulling from both bores instead of one bore .
Scott Grumpybastard yeah this happens in real drag cars ( naturaly aspirated )at the track during launches but most all cars have a drop in oil pressure due to the oil being pulled away from the oil pickup so they need a sump system, but I thought this might apply here.
That door transition...man that was pro level stuff
I don't give a damn if it was slow, that was the best GP run of all time.
awfulinternet agreed. And a slightly shorter wheelbase would have made it a shitload faster.
No doubt... How's your back, Isaac? LOL
That is the best sounding "Lawn mower" engine I have ever heard!..She sounds MEAN!..Hopefully once you get the Mikuni carb installed & tuned it will really come alive
Cryptonight thanks
Kick ass project. Been following for a long time.
FriscoBoater's Garage what’s up Jay? Ready to see the new projects soon.
I am ready to work on them. The Scimitar should be here later this week or early next.
hey Frisco's, love your vids!
Thank you! I have a big series coming up. Right now I just get my fix watching carsandcameras
Same here. Been watching this from day one... There needs to be an NHRA class for hkme built vtwin cars.
Man I look forward to watching y’all every time I see a new video pop up so keep building
Awesome video guys! The dragster is too cool and I love the way it sounds! Thanks for the great video... Subbed!
Omg, the scene switch at 2:06 is so clean😂😂 has to watch it 3 times before I knew it was a scene switch
yeah, even tho the time doesnt seem different, it does look like it launches a lot harder. i think you're dealing with some wheel spin at this point. sounds beasty too
"You need to look at your rear tires and axle"... the hub at 13:15 has a wiggle with next clip on left side also. Its not deflection, maybe it's from tooling around the yard with that frame. I liked when it jumped the tree roots. This thing sounds so cool. Just like the movie with Cheech and Chong...... he has the harley on porch just to bother neighbors when he hits the throttle . I'd do the same thing and stay stationary just flooring it, LOL
I think we need to go back to the drag strip before we put a new carb on it!
Mine jr has a 1.78 60 ft at drag track
CarsandCameras you think you should that would uh old be awesome
It would be fun to see the difference the new car makes.
CarsandCameras swap it at the strip so you can do before and after in the same day.
Why dont you go dual carb setup?
The fridge transition lmao
Beautiful
Mommy and Daddy are going to get mad at the tracks you left in the yard LMAO
Johnny V baby but at least the ....boys.... aren't in the shed smoking crack!
Johnny V baby dont be a hater
Jealous much?
Johnny V baby yeah lol
Na just mommy
Nothing beats doing shenanigans in a garage with a likeminded friend
you guys are not using the stall correct. for example: if you guys have 3500 stall springs you need to bring the rpm's up to (around) 3350-3400 . right before it locks and then launch the rail. try it when you get it running right. I think you will be happy with it. also you need to find out what kind of rpm's your running at the drag strip. for example again: if your motor is good to 6000 rpm's ? then you need to make sure you have it gear to pull that kind of rpm's at the finish line.
goodluck guys. you need to come to symco wis this august and drag race one of your minibikes on a clay track,125ft. 85 bikes, 5 classes last year.
I was thinking the same thing, but their torque converter is just a belt driven CVT, not a fluid torque converter with a stator like a car, it would probably help to run the engine up to stall before launch but they're gonna toast their belts real quick doing that
It's a variomatic... Exactly The same as a jr dragster... Belt does not slip..
they won't chew the belt up. it's made to handle that kind of power.
Yeah it can handle the power, but it will just melt when if they stall it for too long, even if it doesn't melt it will get flat spots on the belt and it won't be nearly as effective after that
have you every run a torque converter with a stall setup. it won't melt or flat spot. I run a salsbury 340 unit on a 15+hp minibike engine. setup for clay/dirt drags with 3400 stall springs with a 20 series comet belt...…. no problems.

really cool refrigerator edit. super clean!
that thing sounds great.
Like a mini Harley lol
That was an amazing transition to the next scene through the door.
Dragster on the Cars and Cameras GP!?!? YES!!!!
Glad to see y'all bringing it back. Hope to see the her dog or Murray at busco
You guys are my go to UA-cam channel !!! Greetings from Arkansas. Keep it up guys !!! It'll be fine...
Thanks!
Hi fellow Hillbilly! (^_^)/ [meant as a compliment, not an insult, I too live in Arkansas]
did you see the rear wheels during the slow mo... pure power...nice guys
GUYS its time... 2 motors on the dragster .. tractor pull type, but for the strip.. Guys it has to be done the dragster is to awseome and to beautiful not be able to smoke the tires off an make screaming passes on the track...you guys know it would be so fun, and for us to..
Wisconsin Robin = 2 Predators. A bit heavier, but amazingly compact small V-4 which would almost fit without mods [I said 'ALMOST' people...] and, although a bit heavier [cast iron block and heads] its one excellent block to power build!
I found a few on E-bay, this one is moderately priced, great photos of how they are laid out, perfect for flat plate mounting, although you have a whole lot of sheet tin that you might want to negotiate with fiberglass to save a little weight, in the end, even though it is ONLY rated as 30hp with the dinky little 1bbl carb, with a few tweaks and a good set of motorcycle carbs it would probably turn out 120-150 Hp pretty easily.

Delicious DeBlair hell ya
Just put on a Hemi v8 lol. But in all seriousness, the dragster needs some linelock so it can do burnouts (I'm new to the channel so Idk if it already has linelock or not)
Delicious DeBlair. The Wisconsin Robin V4 is 1760 CC. Making its width at least equal to an 875 CC engine. Vs their 670 CC V twin mounted longitudinally. Which would be a least 350 CC width engine.
Aries Might
There is no such thing as a V4
The transition are gold!
This is so cool
The dragster sounds insane, Never gets old.
HAVE YOU THOUGHT ABOUT DUEL CARBS??? It is a V-TWIN type of engine isn't it?? So i figured DOUBLE-DOUBLE,.. Basically same way the Yamaha Banshee 350Twin... Mine had duel carbs and she really screamed, eh!! depends on taste of builder i guess, some would put the single carb on them but bigger size(a lot bigger) i think i had duel 36mm on mine:factory was 28mm i think but i'm not 100% on that, been a long time ago...
MY POINT being; wouldn't a double carb setup bring out or unleash THE BEAST?
However i enjoyed the video clip.. KEEP'EM COMIN' ! ! !
BlkiceMike single keeps it simple
Banshee comes from the factory with dual carbs
uh??? yep...
Enjoying this dragster video. Reminds me of my friend when we were having fun making toys like this.
Looking from the rear when you start to move it looks like the axel or the frame is flexing or is not tight in the frame Guys. when you are in slowmo on take off.
pretty sure that's axle flex when its under load. don't look good! and damn the chains look scary lol in the slow mo
WA. PREPPER that isn't a car bro in you pic check out mine. 71 mach1 cj 429 ram air. 982 hp.
If you now cars this car is a full custom from the ground up never came of off a assembly line it does have 429 twin turbos and NOS on full cage . I will let you think what the HP is.
Okay. I haven't watched one your videos in like 3 months, but I am still subscribed. This was definitely like a nice welcome back with my favorite, the dragster!
S B thanks for watching
Isaac it'll be fine No thank you! You've been making these awesome videos. Keep it up!
Heeyy carsandcameras!!! I love the videos and your channel, keep up the good work!! This is my favorite channel on youtube!! 👍👍👍
Mason Dagenais thanks for watching
no problem! by the way do you have a suggestion for a new go kart engine? the one on mine died...
Predator 212 is definitely best bang for the buck!
How could we not laugh at Ike's reaction while he sticks his leg on the brakes! xD
keven977 it made me laugh. After
that was good editing man
Mount the battery behind the seat!(for wheedles) Or get a smaller battery/ lighter? the big battery on it must be like 50 lbs. just a good place to start with reducing weight :) ps I love the cuts in the editing + the burnout on grass was super cool!
Crazy cal
Yea I got a Braille.
It’ll start my diesel car down to 30, it weighs 15 pounds and is half the width of a normal garden tractor battery.
Not cheap at around 180 but I saved about 30 pounds off my front end in my car.
That’s a big help when it’s only rated at 52hp.
when i say baby i was like wut then i saw wheelies and i was like oh ya baby time fuh wheelies!
It's so good to see the drag rail again. I've been missing it
What about a turbo, or even crazier twin turbos. I know you put a turbo on a go-kart a while ago, but it's a dragster, it needs the acceleration.
Single turbo would be better. Especially with 2 cylinders feeding it instead of one.
Vz21 turbo would do it
Turbo would have too much lag on it. A belt drive centrifugal supercharger would work better. Basically a turbocharger with a belt drive system. Had one like that on my GTA.
Thomas Strickland a single turbo would be mechanically simpler ...and if sized correctly the wouldnt be much lag at all especially with their stall setup. If they wanted to boost more volume at less pressure to make more power they could set up a nitrous system either in the induction system or in the exhaust as an anti lag wet shot
We would need either a draw-through setup (which has performed poorly for us in the past on the drift trike) or an expensive custom EFI system. On top of that, we'd need a custom ground cam with minimal overlap- forced induction gains are marginal without the proper cam.
Found your UA-cam channel and man I like it! Once I get my house renos done and shop organized. I so want to make my own drag go cart. I like wrenching and making thing and on here you do both. In my province up in Canada i don't think we have anything like this and I do want to try this at HOME.
turbo the drag rail
Mighty Marshmallow buy a N0S kit for it, they make one for the 212 😂
jeff wheeler why not both
Nitrous wet shot right after the exhaust ports. Anti lag, anyone?
both👍
Yes , turbo the drag rail
Ok, I am new here. Happen to run across a recent vid you guys posted. Would like to say. This machine is a beast. Sounds killer!
I don't much about these engines. Although I have been around small motors my whole life. The quad in my profile pic is a single cylinder 450cc and after tuning we got it to 53hp at the rear wheels. Keep it up! Enjoy this!
Lord Motorsports I like your name, LM!
TammySue PattyPan - Thank you!
Thanks!
Lord Motorsports thanks for joining us
Who ever reads this have a great day and also first.
jordan shope have a good day to, my friends name is Jordan
Thanks for subbing
offroadz bro no problem man
Those transitions had me a little stunned. Great video and awesome dragster!
It looks amazing, but it just does not look like it making a full 50hp, seems like it would be a lot faster
I don't even think they have shaved the heads on it or anything yet, have they?
Keagan Knapp its heavy
some of the smoothest editing on UA-cam, nice work gents. im loving all the infamous projects and the cars and camera grand prix is great. Love from socal
Can’t you put a VOLKSWAGEN VW 1968 PORSCHE 912 SMOG PUMP as a supercharger
CykelPotatis little bit small, but a amr300 or 500 would be awesome
Would be great on the rail.
They run about 1500 bucks in the states
Get one from a salvage yard or E-bay?
огромная эрекция if I knew a crackhead smart enough to know what one was I'd be all over it
the transitions in your guys videos are amazing
fuel injection guys!!
sweet edit opening the door and going to the next scene
I love the dragster its real american just made my morn thanks guys
Michael Mcginnis. The engine is chinese isn’t it?
Im not to sure the dragster is all american and they built it minus the cast parts.
Michael Mcginnis. Let’s compromise and call it partly american. ;-)
It’s a nice build and it’s looking good. A lot of time and effort certainly went into building this thing.
Hey guys! Japanese 660cc Kei cars have little mini roots superchargers avaliable on some models! Do it!
Still misfires... WTH? Frustrating issue
it's the plug gaps.
Too wide?
BWX is there ground clean it up.
11:13 - That's what she said! And Ike knows it too!!!! 😂
360p club boys
Rhys Aistrope
720p60
144p 😂 I can hardly tell why i’m looking at lol
1060p
mi550key that’s not even possible lol
13:24 onwards it looks as though either your axle is twisting or the wheel nuts/bolts are loose. Bit of wobble on those back tyres. Probably nothing but thought I’d mention it. Awesome video, that cam sounds mint!!! 👌🏻👌🏻
Lmao, get a drink out of the fridge
Awesome guys! Try to get rid of the wobble from rear wheels might give you some extra speed, kinda clear what's going on in the slowmotion @13:30
Just put the ducati engine in it for god sake !!!!
Then it would be down right scary fast
J.Fish after they have gotten all they can get out of this I agree
They have a roll cage, what's to be scared of?
Ian s I was thinking the same, i think the 670 is limited by the CVT clutches. I think they maybe should have put the 670 in the margay chassis, and then put the Ducati Monster in the rail, first, it would get rid of all those kinda sketchy jack shafts they had to use to make it work and it would give it 5 gears to actually make it drag. But the ducati in the margay is pretty Absolute, just get another performance motorcycle engine for the rail.
Get a Ninja 1100 twin turbo! (~_^)-b
2:06 that transition was dope.
Since they don't answer messages on Facebook it's good to see they finally figured out there carburetion is way too small. It's misfiring because it's starving for air. I've worked with v twins since 1989 when the first Vanguard was made. They should be running a pair of 28 mm Mikunis. It seems like a lot but trust me it's what it needs.
Might not be your problem but when we build pipes like that at work for choppers. The Harley motors seem to respond better with a added “baffle” which we just put a dectorative cover on the end of the pipe or something on the end of the pipe to baffle it some seems to help with back pressure rather than straight through.
Your back wheels flex like crazy, can see it in the slow mo
I cant wait to see this thing go to the 1/8 mile!
It ran better when u cut intake, cuz that adds more intake volume and that gives you more low end torque... ive done tons of intake mods on v8s...
Make the straight edges more round, and it will get better fuel distribution
With the wheel spin. I would recommend softening the tires. A good brand to use is HMS extreme. Don't take much to soften the tires. Just need to deflate the tires, take out valve stem core. Squirt in side tire and spin tire till assumed dry. Then to have a more effective soften also spray the tires on the outside. Wrap in paper towler and then spray paper towel. Then wrap tire in some sort of plastic wrap (bag,etc) an let sit till paper towel is dry.
You guys are killin it!! Thankyou for all the haard work guys!
One of my favorite builds guys 👍👍 and I'm sorry (not sorry) but when ike hit the hot brake rotor I spat food out in laughter 😂😂 half cause itd funny af and the other half knows damn well what unexpected heat to skin feels like! Looking forward to the drag strip!
2:26 that was so smooth
3:55 eating the ground 😂
The mod you did to the carb is a great idea for a cammed engine, it does not need to be shaped to flow (it is better to set up as a H pipe like you did) the purpose is to equalise carb vacumm (enlarges your tuning window) and prevent reversion pressure from reaching the carb.....
In the 45mm Weber and dellorto world it's known as a balance bar
@carsandcameras you have the right idea on putting the gap in between the two barrels of the carb you gust did it in the wrong spot you should do it right behind the carb and the bigger the space the better. Engine masters actually tested that on the Dyno and made decent improvements I forget the episode number. Also by doing that you will effectively dubbe the size of the carb. From what I can tell you are spot on on it being like 2 separate carbs. Also on launch you should hold the break and gas so your rpms u faster on launch but you might break traction don’t know
OMG your Dad's lawn was all I was thinking
How to check the stall speed on the converter- Remove the belt, use a fairly accurate tach. bring the engine speed up watching the tach- when the faces of the sheaves (the part that moves to contact the belt) closes up, that's your stall speed. On a Jr dragster, you set the idle speed to almost that point, so the car creeps into the staging beams, without touching the accelerator. The high idle helps the launch.
Have fun and update us soon.
On my $8000 audio system the rail sounds great!!!!!
You guys are on fire lately ,keep up the good work
love the hole door thing but it made me a bit twisted for s few sec. then you got me again lol
Of all the builds, this is my favorite.
Love the door opening edit run dual 24mm carbs!
That fridge transition 10/10
A lot of comments regarding gearing. This torque converter wether stalled up or down still raises overall top gear as cart goes down the track correct? So set stall for maximum torque and final gear should be at max horsepower rpm going through the traps. 60 foot times may be slower for better overall elapsed time. Gonna take alot of different runs. A dyno for a day may be best option to run simulated 1/8 passes.
i can watch you guys ALL DAY
I had a twin Honda shadow do that same break up and I made the plug gap smaller and it ran perfect...big difference
