20HP, 9,000 RPM Engine Build! 88MPH Kart Pt. 3
ฝัง
- เผยแพร่เมื่อ 12 ก.ย. 2024
- We’re building an 88mph back to the future inspired go kart from the American Express 2.0 go kart kit from Go Power Sports. To achieve 88mph, we need a very powerful engine, which is why we’re building a hemi head Predator 212cc engine with really high performance and brand new engine mods, like a 24mm flat slide carburetor, elongated billet rod, oversized valves, and more. We’re taking this popular 212cc 6.5 horse power go kart engine and making it turn 9,000 RPM and put out about 20 horse power.
Thanks for Watching!

As an engine builder.. you need to know that the aluminum rod will expand when it heats up, about twice as much as a steel rod. Measure your deck clearance at TDC after you assemble everything to make sure the piston wont smack into the head. I'm sure the maker of the rod will have a recommendation, but on the engines I build, aluminum rods usually need .060 to survive... CC your head, and piston, so you can calculate your compression. Will let you know how much room you have to wiggle.
How would I do this? Would I adjust the valvelash to a different spec? Please get back to me as I’m interested in making a high rpm engine build
"Opened her up and smoothed her out"... Id buy that tshirt. ;)
LoL
I really enjoy watching you guys do mods to these small engines. None of which I've ever tried. Now however if I was so enclined to do so, I'd feel more comfortable doing them.
Keep up the fantastic informative/educational help video's!!! 😊
Wow! Go Power Sports should really bundle all these engine parts together to make an ultimate performance package! I would love something like this for my go kart
I see channels like this installing the kits, but I totally agree they should make signature kits designed and tested by them. It would be a great partnership.
Love the little transitions you do when you go places
Isaac,s girlfriend just giggled a little at the end of the porting section
What time
if you cant work it out you probably dont need to know LOL
rob burdack no I'm just lazy
fingers does usually open her up hahahaha
skrewy lewy No joke so true
I realy like the post-commentary. It gives more time to thevideos and makes the building parts more exiting.
This new build style where we get to watch how you do everything is AWESOME! The explanation and speed were perfect. Hope to see more detailed builds like this!
If you ever decide to build another amphibious go-kart or maybe a Predator powered paddle-wheeler/stern-wheeler boat I might be willing to give you my 1974 Boston Whaler 13' boat (w/title) if you would use it for the channel.
Could become a cool little river boat to travel from Washington, NC to Greenville, NC and back? Just a thought...
thats my area n.c.
thank you for having proper audio levels during the voice over. i dont know why so many people have trouble with that part but you nailed it.
@ 13:20 that just doesn't look right... LOL
JeepCollector91 neither looks or sounds right hahah
That Shit Hurted
JeepCollector91 😂
Prison style polishing
he opened her up and smoothed her out
I love the voice over it allows you guys to keep working without stopping every 2 seconds
That little crankshaft is so cute lol
Hey guys, big fan. Love your videos. Just want to point out that there are dramatic differences on torque specs with wet or dry bolt threads. Torque specs are generally dry unless specified. If you use provided torque specs, it is intended for dry threads, no lube or thread lock. If you use those specs with wet (lubricated or thread lock) threads, you can over torque the threads. Keep making great videos. You've brought life back to my love for go karts.
*IT'S HEAD TIME*
Dude this is the nicest build yet
I can't wait to see this engine running. Great video guys
Mini Bike Addict216 yeah I'm stoked to see if they hit 90 or better. Here's to hoping!
I dig the editing cuts you guys keep putting out better and better content 👌🏼👌🏼 love you two!
Lol how did it take this long for you guys to get a torque wrench
6:33
dont you get it ? ill be fine.. and then some broken engineblocks later they changed mind xD
They still don't have one. They bought 12-point sockets^^
me and my brother dont have on and he just bought a cylinder for his 2stroke moped 1 week ago now its lost its power
you did a top end rebuild without a torque wrench, dumb fucks
Y'all are really stepping up your game with the transitions between shots.
Like kids on Christmas morning!! Enjoy!!
GREAT TIP for beginners..."EXAUST ONLY" Love it.
2:51 when the music started and jon's voiceover kicked in i thought you had completely lost your mind and were rapping :D :D
Thanks for all the great videos Ike and john will always watch forever.
I love how you left the go pro on the helmet! Haha
That was misleading Ike building us up for the valve job with John just to have him close the video.
i had build up problems last night
that exhaust port is beautiful :O
can't wait to see her rip
just saying, i love the camera mounts for the montage
That exhaust port polishing with a finger, just gold.
Best channel EVA!!!!
Still onpoint with your transitions store to shop 645. Lovin it.
so John leaves for the day, and comes back to end the show just when it's getting good, that sux!!
I used the polish wheel and compound from my Dremel to polish. That makes for a mirror finish!
camjamsdad correct. That's all I polished was the exhaust.
We use the exact chain and clutch on the mini cup. I love the videos. Gonna run out of data watching them
Looks like one wicked predator. Can't wait to hear the rpm hit 9k!
I just got done tearing into a 5.5 hp engine to get a free log splitter running so i had to watch this. One thought, I was told once that torque specs are only accurate for clean dry threads, so any substance from never seize to silicone to motor oil throws off the accuracy of a torque wrench. Not sure how much, probably a whole video worth of research here but thought I'd chime in when i saw y'all lube the threads of the one bolt you wanted to be sure about torque-ing down.
ON A PREDATOR!!!.... HELL YEAH!
Go boys go! Good luck. You guys are on somthin here!
Looking forward to seeing the end project.
If you are going to shave the head with sand paper get the glue back stuff and stick it to a piece of glass and hand sand. This technique leaves the best/perfectly flat mating surfaces you need at those rpms. Also you really should polish the exhaust runner as well as the combustion chamber as it will reduce the heat that transfers into the head during and after combustion which may cause your valve seats to eventually fail at those rpms not to mention mess with your valve lash settings (best way to lash valves is with the engine at operating temperature too).
I cant believe the amazing work that comes from your channel. Keep it up guys
Wow, stage 47.20. I love it.
Fingering the Exhaust port... pretty good idea lol
That was a great goody box from go power sports. And the con for was a thing of beauty
Impressive Engineering on that rod
Thanks guys looks like a fun build.
I can’t wait a week for the next episode!!!
That clutch tho ...😎😁 ,its about time...
More ct70s please?!! Enjoy the videos😄
Now this is the kinda videos I really like to see you guys doing!! Great work so far
So happy this video is out! Love all your videos both of you! Thanks for the best entertainment for me and much more:)
I enjoy watching your videos hopefully you record. Hopefully we see you guys can video the older rigs that you're going to go see this weekend that be cool
Gotta admit, you sanding that exhaust port really got my motor revving!
That is one hell of a engine
Hey guys love your work from Australia
Finger banged to perfection that exhaust port..
Its cool to see all these youtubers from around my area. We need a mr.beast and c&c collab
You should contract *cc specialty tools* , I bet you they would Give you a KickAss Deal of a Full Set of Porting tools!
Great guys to deal with , i got a few toys from them over the years.
don't shave that head, really!! at high RPM the higher compression is going to hammer wrist pin and rod bearing even harder. for really high RPM's you want a little lower compression, because high compression can also act to limit RPM's lower. really high compression is great for more torque+power at lower RPM's, but you're trying to spin this up like a 2-stroke!
you've already got .020 gain with that rod, you can always try a thinner head gasket or head shaving later, be safe!
model nutty I agree
This^^^
no, compression has nothing to do with rpm. and if so it helps to get even higher rpm since there is a bigger explosion to push the piston down the bore. and they said that the original rod is weak the ARC rod will easily take the forces
Alright man
13:20 lol... opened her up and smoothed her out. 😂😂😂
I have been waiting 5 hours for this video
Nick Schmidt me to
more like a week but yeah
This was very satisfying to watch! Thank You for Your awesome content!
great flow work on the 212 head !!!!!!!!!!
The engine is looking nice guys. Keep up the good work
9 grand out of a one banger . . . Sounds wild can't wait to see
dude..the memes is strong with that one..especially the whole exhaust port section!!!
ur vids has been getting better and better i think this is the time to not change a thing anymore, i like!
Building my first kart! Thanks for the inspiration guys.
Could you please do a detailed video on the wiring for a 12v ct70 swap. There’s no good videos online.
Just finger it out on your own, bro!
It's only as hard as we make it out to be!!!
YOU CAN DO ANYTHING YOU PUT YOUR MIND TOO, MY FRIEND.
THE SKYY IS THE LIMIT!!!
@@austinsears1637 WOOOOOOOOO BEANS
Been watching for 2/3 years love the vids
I've never seen rolls of sandpaper like that! Definitely would be MIGHTY handy!
Yes back to the 212's
13:20 Ike just proceeds to finger blast the exhaust port on that poor little head.... and he didn’t even ask for consent 😑 No but for real! Love your videos guys! Keep up the good content! I know this was made like 2 years ago, but the new content is so great too! 😂
You're editing skills have gotten so good!! I've been watching you videos to the end because you have content, and an interesting video. Keep it up! 😃
We want more videos weeklyyyyyyy! Please I’m needing more vids
I love the transitions
Awesome, this will be great to watch. You may even get 88 if you can turn some serious rpm
well sayd Get INN there 13:16 and the movement Priceless i see you got a lot of practise
i dig the funky music tho
Fave episode yet! Thanks guys!
To get more power you can get the air to go through a container full of gas before it gets in to the carburettor .
13:30 you opened her out and smooth her out with that finger action. LOL
It would be awesome to see you guys build a big offroad kart with huge tires on the front and rear.
That thumb nail just forced me to watch this video...cleeeaaaaannnnn!!!!
You guys should invest in a nice flat piece of glass. Glue sandpaper on the glass and use that to shave the head. Move the head on the sandpaper/glass in a figure 8. Do that 5 times then rotate the orientation 1/4 and repeat.
They just hit a million
a good torque screwdriver is so expensive, but extremely useful when you actually need it
My dad and i have gotten a couple of the Predator engines to do 32HP and would rev over 10k all day long. The things were mad!
you should have put a 400 stroke crank in it and changed the carb to run on methenol too. then it would have ben a monster. i used to build these engins like this all the time when i raced co karts . good job
Welded head, 28.5mm intake valve, stock 25mm exhaust valve stainless. Stainless 2 peace keepers 26lb springs ported and polished all done by Brad Hill Performance. Stock piston billet rod .020" longer then stock rod dyno 335cl grind cam and a 22mm-26mm carb. 22-24hp easy thats with stock rockers and stock push rods and lobe tappets.
Also for the life of the engine and most hp i would highly consider having the crankshaft balanced after 4,000rpm. Everything you do to a car/truck engine you do to the small engines. Same concepts if that makes any sense. Hope this helps more then the other comment😂
104 views in 34 seconds. Geeezzzzz !!!!! Lol
Great video guys!
Ike, instead of wrapping sandpaper around your finger you can get various grits of flap wheels for your die grinder & you can carefully cut a slit into a piece of 1/4" steel rod and use pieces of roll sandpaper to make a polishing flap wheel. It sure beats using your finger...unless you just really enjoy that kind of thing... ;)
@1:53 And that is why we can't have nice things.... LOL
The original Lucas engine oil additive is a GREAT engine assembly lube me and several friends have built some very high horsepower twin turbo LS motors and never had a problem. It has awesome sticktivity and stays on the parts till you fire it up
"It's head time" and "open her up and smooth her out", this is such a dirty little channel!! I guess you could call the sand paper wrapped around the finger ribbed for the exhaust ports pleasure! I think we might have just watched a secret smut movie.
You really did polish that exhaust port good with you finger
Lol
Love watching you guys, really wish I had the time to do what you guys do. Seen an off road cart here like the redone you guys have for 200 but they said it needs lots of work. If your looking for more carts ill pass it along to you guys. Good luck with this build I nearly cried when Isaac's motor blew on the other cart. Sorry for the loss.
Cant wait to see it run. Im so excited.
Can't wait to see the finished product, and how long it can be beat on before it's toast.
I like the idea its looking good
kind of funny seeing 2 big guys working on a little engine and even one of them going oowww lol
