- เผยแพร่เมื่อ 23 ส.ค. 2022
- Our high performance Predator 670 dragster CVT blows up! The turbo 670cc V twin is ok, but the CVT torque converter driver blew to pieces, taking out a turbo oil line, cracking the carburetor bowl, and knocking off the air filter. The CarsandCameras drag rail blows up in this episode, but we will find a snowmobile transmission, and we'll take our Predator 670cc dragster back to the drag strip soon!

thats about the most impressive way of breaking a torque converter ive ever seen, get yourself a polaris cvt driver those can handle a whole lot more power
Yea it can handle a lot of power but not a lot of rpm they engage at like 3000 and stop at 5500 I think so nah
Comet clutch and a small metal shield for possible failure would work great so you dont catch a clutch weight to the face at 5k+ rpm
Cvtech from canada can handle upwards of 200 hp for a power block the trail block 100+hp polaris and brp guys usualy buy thos or the daltons cvt's
@@BeetleSmasher that’s not how a cvt works
@@BeetleSmasher that’s not how a cvt works look it up if you don’t know
The fact that the engine survived 8,000+ RPM is insane. We definitely need a dedicated CVT guard next time around!
Throw a Sportster engine in there, and put a Hammer Performance 1275 kit in it. Easy 150hp 👍 Plus you get the benefit of a 5 speed gearbox, would be easy to run the clutch cable to a foot pedal and custom fabricate a shift lever that simply goes back and forth. If you're feeling really creative, you could maybe even have the shift lever work the clutch and change gears in the same movement. Would be kinda awesome.
Or use the Honda 919 engine with turbos it would give out about 150 hp
Luckily the oil didn’t catch fire. The firewall didn’t do its job.
@CarsandCameras pin me if you guys want.
well i did warn you that you needed a transmission and not a chain drive
as i promised before. I TOLD YOU SO!!
now next time get a three speed bike transmission and mount it longitudinal. remember as i said before. guys in the 60's did what you guys are doing. and it worked but it was unreliable and often was prone to failure. thats why the front engine formula always was a longitude style engine postition. i knew something was gonna break in the drive line.. so. will you start taking my advice now?
Scatter shield.
I love the Harley transmission idea. Having a sequential stick shift(or pedal shifters on the steering wheel like on your offroad projects) would be really cool on this project.
HARLEY TRANSMISIÓNS Rob a lot of H. P. But it will Never Blow up. 👍
@@donalbershardt9290 that’s why they just need a hyabusa drivetrain
Harley parts????
It's already laying down enough oil....
Softail five speed perfect
@@Louzahsol If you ask me the Ducarti has too much power on such a short wheelbase, awesome as it is. That setup with a sequential over paddles in the rail would be insane.
Hey guys, crazy Canuck here. I’ve ridden high performance mountain sleds that have produced up to 320 hp, that particular sled ran a Polaris four post primary clutch on the engine and could withstand the 9500 rpm the engine turned at. Talk to sledders, they can help you determine the correct weight and spring combination to obtain optimum shift rpm while maintaining maximum grip on the belt. Plus as an added bonus you have limited adjustment of your stall speed which should help your hole shot tremendously. Also keep in mind snowmobile belts can handle huge horsepower and not fail. On a safety note! Put a belt guard on that thing! I once got hit by a piece of belt frac after it bounced around engine compartment than came out through the hood and hit me in the shoulder, it left a bruise and sore shoulder for about three weeks! You fella’s are entering fatale speed territory, take some precautions please! I just found this Chanel and I want to see lots more of your ingenuity and insanity! I love it! A machine built from scratch using components never before mated and than tuning it til it goes killer fast…. What more is there!?!? Oh! Wait! (HEADSLAP) That’s right! Make it go faster!! Thanks for the great content from a new subscriber, stay safe, motor on!

Mel from Quesnel
I respect the fact they show and explain the failures. Back yard ingenuity at it's best. Thank you, gentlemen.

With all those flying parts that’s a good indication you might need a scatter shield. Safety safety.
th-cam.com/video/JqzuJaeykW8/w-d-xo.html
I always warn people to put a guard on their torque converters because they blow up like a grenade. they dont care
Yup, 100%. Even if they are too cool for all the safety, they seem quite embarrassed about oiling down the track and a good shield would have solved that too.
Agreed, scatter shield is a must. It was lucky those pieces flew up and forwards a bit.
Keep going guys, 60 something year old guy here is pulling for you all.
gotta protect them primary investments. never underestimate the bottom line.
I saw my name on the Dragster! I didn't realize I'd be this excited about it. I haven't felt this happy in a long time. Barely keeping a roof over my family's head, but seeing my name really felt awesome. Thanks guys
Good thing he stayed right in the middle of the track to ensure maximum oil coverage.
massive facepalm seeing that - no1 rule broken!, so ignorant
With all the fuel that came pouring out, you can see the need for a fire proof hood, worn under the helmet, that covers your neck. So glad the fuel did not ignite. I have seen the results of fire on a slingshot style drag rail at 2 of my drag strips and the end result was horrifying and sad. You have a nice set of race trim leathers, but really need a little more protection. Your fans want you to remain healthy and safe. Just finished watching and found out the liquid was oil, not fuel. You're extremely fortunate Ike. I was wondering why, what I thought was fuel, did not ignite.
th-cam.com/video/JqzuJaeykW8/w-d-xo.html
the fuel was pouring on the battery.. plus hot oil..
so glad that guy from 1997 with the puka shell necklace is fine!
They severely lack in safety equipment and almost every video that I have watched. They are very lucky the serious injury to Isaac's shoulder was the only thing that has occurred so far. Riding bikes most of my life everyone knows when you go down even on a bicycle the first thing you try and stop your fall with is your hands and they turn into hamburger but yet they don't wear gloves at least 90% of the time. A lot of young kids I'm sure watch these videos and this is no example as far as safety goes they need to look into that or it's possible someone might report them. And yes everybody wants all of them safe and healthy it's not that big a deal and you don't look like a wuss just because you protect yourself with proper gear but it appears they don't listen as I have made this recommendation well over a year ago multiple times. I'm surprised the track doesn't require it.
Disaster awaits for those who disrespect safety considerations - like the dude who was severely injured at one of the Cleetus Freedom Factory events who should have been safety flagged. Any type of open wheel vehicle has a whole different set of safety concerns.
He was damn lucky, he coulded burn to death.
Use a snowmobile CVT. Right off a sled. Many are good for 150hp. Plus much aftermarket support with weights and spring's to keep the engine in the perfect RPM.
I would love to see you guys try a XCR Polaris 800 engine and clutches. That would pull 100mph in the 1/8th
th-cam.com/video/JqzuJaeykW8/w-d-xo.html
Yea, it would be nice to get them rippims up past that stumble before you engage drive.
Something tells me it’s not a great idea to use a cvt because if it slips the belt like this one did it could make a bigger more potentially lethal bang, a trans and clutch from a motorcycle makes more sense just for safety, sleds are robust but they’re not built for top tier traction on prepped surfaces and could be even more prone to slipping a belt and blowing up the cvt, I’m not completely for or against a cvt but from seeing how everything went down that idea should go to a future project where centrifugal force, who knows how many rpm, and potential belt slipping upon launch is less likely to harm Ike
Yep use a snowmobile clutch Some of them will handle a lot of power and rpms wont be a issue
@@stevenbryant3055 clutch blowing up isn’t an issue, You usually have the entire cvt system enclosed in stainless steel.
It was a great honor meeting you guys at a RC shop. I am the Autistic guy that loves people. Thank you so much for making the trip to see everyone from Anderson RC. God bless you guys. From Mark Hunter!
Dude I’m so happy I made it on the firewall! That means so much to me, love the t shirt too! You guys are awesome and I hope you guys keep motivated with the drag rail it’s my favorite project so far! Have you thought about drilling out the emulsion tube in the carb? That could be limiting you on the fueling side, I think the reason the 38mm didn’t work was the engine wasn’t pulling enough air to create a strong enough signal to pull fuel through it.
You may have to buy like a Comet 102c or 108c setup. They are upgraded CVT clutches for older 2 stroke snowmobiles. They hold up to 100hp or so.
They would run the secondary backwards and have the same problem!
and are good for 10000+ rpm
@@NotMeeither How would they have the same problem? It has a much higher rating than most anything on the market. They would need a 30mm tapered sleeve and get weights for it. Also need the 90D driven or 100D driven pulley.
I've personally run 200hp through a 102 and it held up good
@@bolkegard they would have issues with it not fully engaging if the engine can only rev to 8500 rpm, they could spray with nos for those extra revs but then probably only get 9k out of it
Time to go EFI with launch control and a hard RPM limiter.
(Check out speeduino!)
That's over a $1000 there
I was thinking the same thing.
For sure
@@Ratkill9000 only if you purchase new. and considering what they're trying to do its definitely worthwhile
@@Ratkill9000 that’s why we’re buying merch tho right
A 4 or 5 speed Harley trans would give you obvious gear abilities while being compact. Clutch gives all the extra control you want and of course a huge aftermarket.
You guys are so humble. I love that. But I believe everyone understand the situation. I’m glad the driver is 👍.
You forgot the Golden Rule always pull over to the railing's as soon as you have a problem it makes sure as little as possible fluids are dropped on the main track, clean up can be quicker.
I thought of that too, but the smoke screen didn't help, might just as easily hot the wall. By the time the smoke cleared it was nearly at a standstill.
I was thinking the same thing but you can see as soon as it blows The camera and Ike's goggles were covered. Maybe he wasn't able to see well enough to get to the side
Did you see his goggles? They were covered in oil and he probably couldn’t see well. Also, he was between the grooves. Had he moved to the side, he would have dumped oil across the actual surface that most cars have rubber on. You can see the two tracks that cars follow, oil in the middle is less of a problem than oil crossing those tracks. In this case, staying in the middle was probably the best option.
I was thrilled to have the chance to witness this first hand! Hate that it broke but glad everyone was ok! I’m happy to meet y’all as well! Hope to see y’all at the track again soon!
I just remembered why I like your rail goKart so much. Reminds me of the Zingers Cars of the 70's 👍🇺🇲🇺🇲
BUMMER ! GLAD HE DIDN'T GET HURT ! I like the Harley Transmission idea. Or something like that . That is One Tough Engine y'all have Built !
No damage on the firewall yet it's scratched to high hell 😂
My vote is to go for snowmobile CVT next, it's will definitely hold up to the RPM y'all are looking for to run through it, you'll get a better gear ratio and there's a huge aftermarket. 👍👍
No third Jack shaft 🤦
This ^^
Its not scratched at all, if you pause and look closely you can tell its all wet grass and stuff thats stuck to it
Sure you can find used snowmobile parts online cheap and get them sent south. Check marketplace or Clist from Michigan or Wisconsin
Yeah they definitely handle the rpm around 8k on the regular not sure why they even bothered trying to run this tc.
just a little advice for the next time something happens at the track. As soon as you can get pulled over as close to the wall as possible to avoid dumping oil in the Grove or right in the middle of the track. people will hate you less
That that crew left chunks on the track the rest of the night is pretty sad.
what I can't understand is this whole thing is, 1off. why not start with a Jr. dragster. or better yet run em 4 deep.
I'm happy that no one hurt when the cvt let go, I got idea for build for you and all the TH-camrs you know and some don't yet know I saw a show of lawn tractor pulls and thought it would be great to see all of the TH-camrs challenge each other to build one and see how far you could pull the sled.
Wow glad Ike is not injured. That waz close.All the best to you all.
Hey Ike, when you blow up at the drag strip you’re supposed to pull over to the side so oil doesn’t get strewn all the way down the track but glad you’re alright , no need to be embarrassed guys, blowing up at the track is part of it, I really wish it would’ve stayed together though cause that sucker really took off at the line til it ran out of gear an went caplooy , patch her back up an make a triumphant return for redemption lol 🤙🏼
Based on the goggles he showed in the pits I'm thinking he couldn't see... Better off to keep it in the middle then run it into the wall
Get over.
@@tylerrussell6779 Well since the helmet cam represents what Ike is seeing, it was also covered in oil. So definitely he wasn't able to see anything to drive or pull over properly.
Definitely needs a transmission. Would love to see y'all banging gears down the track.
Yep, I totally understand their hesitation of "well it would require redesigning...", but it looks like its that time. CVTs only get you so far. I think that was the biggest weakness of RBGs supercharged buggy too. He basically stopped doing videos on it after he built it.
Yep a Harley transmission would get the job done and aren't overly expensive for a used stock one
@@reviewaccount469 I mean there's snowmobiles that make 200 hp, they can run a CVT on a 670 harbor freight engine. Only question is getting the right CVT
I think they need to do like a CRF450R engine or maybe even a 2 Cylindr CBR500 Engine.... Or a 2010 or newer EFI/Electric start YZ450F engine. Honestly they need to get rid of the Harbor Freight garbage engine. The YZ450F makes already 60 HP stock plus boost would probably put it in the 100 HP range all stock.
@@Robert-qm7yi For the price of the "right CVT," it might be cheaper to just screw in a tranny from a busted Harley.
Whatever you do add a scatter shield around the setup. Glad to see no one got hurt.
It was great being there. Unfortunate that it broke after just half a pass but thankfully it wasn't worse. Tracks can be cleaned up! While in staging and waiting for the track to go green again I didn't hear anyone complaining about the situation. Everyone was just chilling around their cars and checking each others out.
CVTech makes a great cvt that’s typically used in snowmobiles. I’m part of an SAE baja team and we also use a custom CVT made my gaged engineering however I’m not sure what their max power and rpm specs are. CVTechs have like a 3:1 starting ratio and finish at like a .47:1 and gaged starts at 3.9:1 and finishes at .9:1. Hope this helps.
Yep, have to agree. Time for a snowmobile transmission, and a decent shatter guard.
I'm surprised you've stuck around with this particular CVT for so long seeing how it wasn't fit for purpose at all
The actual Comet rating is like 18hp so I'm surprised it lasted this long. I've looked at the spec sheets, you can down load the PDF sheets still
@@Ratkill9000 things a piece of 💩. I have one. only reason it works on there application is because they're sponsored by GPS
That was just stupid to even try the dragstrip with that CTV...
th-cam.com/video/JqzuJaeykW8/w-d-xo.html
@@villemil not only stupid but also reckless and ignorant. They're lucky this didn't happen sooner.
I love it when John breaks out that Carolina twang!
Ike looking like he is getting ready to haul ass to the Roxbury. Killing the 90's from part love it
It was loads of fun meeting you guys at the dragstrip! Keep up the great builds!!
“We’re gonna show exactly what happened”
Bruh in the last episode, you said the torque converter was for like 16 or 18 hp. We all expected this.
Dude I called it. A few videos ago I made a comment on how the torque converter was too flimsy for that power output and how they should switch to a more powerful one or they would have problems (lo and behold), I recommended a NORAM 50hp centrifugal clutch.
That is why the newer dragsters have the driver in front of the engine, with a shield separating the engine and driver. That could have been really really bad, glad the driver is ok.
You guys are awesome! You have experienced what all those who push the limits experience, the limit. Now you know your equipment's present weakness and have a place to focus on. Keep on pushing!
"It'll be fine" is a nice, chill attitude to have in general, and great for youtube content when things goes sideways.
But sometimes it just isnt good enough. Especially when playing with more power, nitro/methanol fuel, and parts that are, in all honesty, likely to blow up.
Disregarding oil and pieces on the track, tech inspections and safety regs were often written in blood. Flying parts and potential alcohol invisible fires are no laughing matter. Please take this just a bit more seriously, we want to keep having you around.
/old racer.
Somebody get these boys a clutch assembly out of like a ZR-600, STAT!
Did a snowmobile clutch years ago from a 70’s Kawasaki that needed a taper shaft mount. Never touched the straight shaft out of the engine. Made the taper sleeve piece that did not have a key way for the fit piece. Kept taking small shavings off the turned shaft to find the right taper angle. Had a longer undersized though bolt inside the taper as an extra long sleeve mounted in the lathe chuck. I could undo the nut check the taper fitment with lapping compound. Once satisfied with shaft taper then re-chucked to do shaft bore with a thou to a couple thou undersized press fit. Did lots of measuring to figure out the cut off length for clutch and engine wall clearance good fit. Heated the taper sleeve, placed on shaft and left a blunt nose on taper mate end for another sleeve to hammer tap taper to engine shaft. Used many different lengths of bolts when finished mounting clutch to new tapered engine shaft. Also left a step collar on engine side for a pickle fork or 3 jaw puller in case I had to pull it off the shaft if I had to replace the engine. And yes it’s like 3 engines later on this flint stone backup high seat open floor full suspension kart. The Kawasaki clutch needed to be tweaked every time the engine changed for spring tension and dawg weights changed for engaging rpm speed, to also not over weight the cvt to find the engines power band of an even acceleration power curve. And not do the fling to high rpm and full clutch engagement and radical tire burn. I wanted the pleasure ride of a full suspension go karting off road crawler if need be driving machine. Just add or remove material till you find you sweet spot. Yeup I bought a couple of belts for the figuring of the right sized parts for my ride. I even had to re drill the low end spring engagement side cause snow machine were like plus 3000 rpm and I was running stock Briggs at first. And then I figured out the dawgs issues... blank slate learning. Oh read up on old sled torque/hp specs and took a guess on the engagement side as I knew most clutch designs as the kid mechanic that I was.. I simply made it work. That frase going back to the drawing board was really a good part of the journey. Lathe and milling machine often are required parts for this type of play... enjoy the go
I can't believe that tech let you out on the track in the first place, but good effort, lost of fun now time to rebuild.
I have been following this channel for several years and I'm generally a fan of what y'all do, but there are several mistakes being made with this build and the result is inevitable.
Firewall, transmission, turbo, nitro, the transverse layout, the socks over the air filters... I would love to see this project succeed but you _need_ to rethink your strategy otherwise this could end very, very badly for someone.
correct, its a nitro sidewinder drag rail. which is the worst drag rail u can ask for. im sure you know these things competed in the NHRA Top fuel class
@@jackmagnium6115 with 6 extra cylinders
Also starting the rail on the ground in the pits is dangerous considering it's belt driven. They need to slow down and think.
That's such a bummer man. I love this project and I enjoy this channel so much. Keep at it guys and I can't wait to see this drag rail full send it soon
So happy to see you guys running this master piece! Maybe adding an under pan will keep oil and parts safe. Also, drilling a bigger orifice on the return oil passage on the turbo will help oil get faster into the oil pan!
CVT is definitely the best for that setup I’d say,the ability to hold constant power output vs using a shifter transmission,plus shifting gears would add time down the track,if it were me I’d try and CVT setup off a higher CC atv,you’d have the ability to upgrade if needed ,love the channel and creativeness that goes into the projects
Might be time to consider a scatter shield for the torque converter as well 😁
Ike, when you have issues like this you need to get out of the groove as quick as you can and to the side to keep from oiling down the whole track. You also need to buy an alcohol carb for it.
I’m sure he knows to get over to the side or out of the grove, he’s been around the drag strip lots. The way his helmet was sprayed with oil he probably couldn’t see.
@@scottjohnson29 obviously not.
He let it coast to a stop, and let it sit.
Ruined the evening for alot of guys that actually have business on the track.
I was standing on the brakes to try to get it to stop and i couldnt see. I think the brakes got oil on them so it took me forever to stop
A complete rebuild would be very cool, and adding com’s while at the drag sounds like a good idea too just to check in on the driver
I end up with a lot of assorted spare parts in my world, channels like this one give me ideas of how to use them 🙂
There's a reason rear-engine dragsters came to be. Glad Isaac is A-OK.
@DAMNED SHARP KNIVES I alway think of Garlits at the Winternationals in '70 when I see a front engine rail.
I just recently subbed. You've got to be safer, as I'm sure you've learned. That dent in the exhaust is terrifying. Glad Ike dodged that bullet.
th-cam.com/video/JqzuJaeykW8/w-d-xo.html
I Love the Sound! Like a big dragster...
This is awesome. I was looking up 670cc rotax engines. lol I run those engines in my 1985 honda odyssey. You guys are doing awesome work.
You guys also need one of those switches (maybe one that you have to press while holding the steering wheel?) that you can easily get to that kills all ignition because that was running for a while with all that fuel going everywhere.
Love all your innovation, starting to go fast enough to start thinking about a better roll cage!
That’s right! Not a terrific example but if you recall Formula 1 - also now 2 and 3 etc - created that Y shape which has proven to be a serious contender of safety for the driver. In this situation, a relevant-to-the-frame shape would certainly be advisable because that aside, Cars and Cameras wouldn’t be the same with any one of these boys out of the picture! Health and Safety first……PLEASE!!
@@2earache Especially Ike, without him, the channel is ruined. Just like Jeremy Clarkson leaving Top Gear, and then later, the channel fell apart since then.
You guys are awesome 👌. I always look forward to seeing new videos from y'all
Didn't have a tach on there. Yeah, and apparently a rev limiter either. Outstanding video! And I'm glad no one got injured.
The 670 has survived the wreck on the mower which needs a revisit it survived the magnets in the flywheel seizing the engine and now a grenaded cvt pulley and 8,000 rpm like a cat it has 9 lives
Get a Baker Transmission and you can bang gears just like a harley. Eliminate the weak clutch’s
You're CVT was wobbling at 4:46. It was damaged before sending it down the track.
Don't be too upset about the blow up. Many people go to the track just to see that sort of spectacle. They may not want to admit it, but we ALL know it's the truth! Keep on keeping on.
Time for drag rail 2.0 hang that one back up on the ceiling and start frame up incorporating everything you learned from the first one to make it even better
One thing you guys don't have to remove your primary clutch to put a new belt on. You just have to put belt on primary clutch and then push in your secondary clutch and slide the on. If you race snowmobiles you change the belt every race so you have a cold new belt for best performance 👌
You need to put a Comet clutch on it.When I raced snowmobiles I ran 180 hp over 100mph in 60p feet.
had a friend whose snowmobile clutch blew up, pieces went through clutch cover/guard and a weight shattered his leg bone right below the knee, be sure to build a heavy guard over the clutches
You guys are getting crazier and crazier, keep having fun!
I think a Harley transmission is the way to go. They'll hold up to the hp and torque and when the engine nears its redline, just shift it. Also I'd recommend a tachometer.
The redesign wouldn’t be that bad surely
I've been saying that since the beginning. They are loosing to much power through the torque converter setup. Then they can rev it dump clutch and go
@@mesanders1113 I have too but I feel like they have to run cvt with their gopowersports sponsorship fr. Back in 2018 when they first ran it I knew the engine wasn't in its powerband, but now that is in its powerband, it blew the cvt up and almost seriously hurt Ike. They need gears STAT
It’s time you put a Streetbike/Harley/snow mobile engine in it and turbo that!
Terrible idea.
They are NOWHERE near ready for that.
“Well we’re using a torque converter rated for 30hp and we are running 60hp…” “yeah I don’t know what happened “ 😅😂
This is why scatter shields, guards, etc...are important. It wouldn't have stopped this but kept stuff from flying everywhere. Drilling holes in the firewall isn't a good idea either. Glad to see everybody is safe but quickly shows how all that fuel could have caused a fire on the driver.
I cried reading the title and my heart dropped into my chest. Thank you guys for the content!
It's not that big of a deal bro 🤣
Did you run to your safe place also and hug yourself? 🤣
Sorry about the dragster and I'm most glad that nobody got hurt I love your drag kart it's awesome
Just got my shirt... love it .. thanks for the extras too...you guys are extra awesome now!!!😁
This could have been so much worse guys , I’m glad you’re safe though but please don’t skip safety 😕🙏🏽
Take care 😉✊🏽
Love the channel and content, but must say I think after "no surprise" "we knew we were Greatly exceeding its limits" and similar comments it was a bad idea to run on a public track for everyone else's sake. Glad no one was injured; best of luck on repairs and future runs, can't wait to watch!
Wait you think these are public tracks? All tracks are private property and people who go to the track are aware of the risks. This was the perfect place for this thing to blow up at. The whole point of having a track is a place to race that’s safely set up for racing and potentially crashing or blowing up
Disappointed at the amount of people who agreed with you enough to leave a like on your comment
@@fernandop937 He ruined EVERYONE else’s fun at the strip that day. I’m sure the OP meant “closed” track. Meaning just him to blow parts everywhere and not annoy fellow racers with the 1 hour of cleanup
@@fernandop937 Gee, I can't imagine why people might criticize someone when they half-ass things frequently, _knowingly_ run parts way beyond their limits, and inconvenience other people as a result.
If only people in the comments had been saying from the start of this that they should get a snowmobile unit that's actually rated for this kind of power...
@@fernandop937 Tracks are private, but they are not there for you to blow stuff up and waste the time of others who also paid to be there. They took out something they knew wasn’t built for what they are throwing at it, and wasted other people’s time and money. I don’t bring a car to the track if I think it’s gonna blow up, I fix it first. Why waste other people’s time that they paid for?
Can't say I couldn't see this happening lol. Next time try to side track the rail to minimize oiling the track
Yeah you should immediately pull to the side off the prepped part of the track fast as u can even if you don't no your leaking anything stop someone will pull up and let you no. The track workers get pissed when people do this.
these guys a few years ago were just like 11yo me and the neighbor kid. if necessity is the father of invention. we got to learn the hard way about things like throttle return springs and kill switches... and now blast shields. love watching these guys.
Been racing SCCA F440/500 for 30+ years - you were using the most primitive of drive clutches - you got the result you prepped you drive train for.
Bad luck, you'll get it right, all the best to yous and your loved ones
love the videos, I hope you keep going to get the next generation into engines🙏👏
Geez that thing was spraying nitro methanol everywhere I was almost certain it was going to ignite…. Guys that was WAY closer to a disaster than I think you’re willing to admit
So glad no one was hurt!
Now you can say.....This Dragster will blow your socks off!
Sounded lean as well, should definitely do a tuning session under a load after switching to nitro and methanol mix, also like they said, use a fire suit rated for what you are doing, no one wants to see you guys fried crispy, sick build, hope you guys meet your time goals safely in the near future!
Man, it almost wasn't fine, might be time for a steel cvt cover/ guard and a perforated fire wall doesn't stop fire, if that fuel or oil had ignited Ike would not have been safe
Dude...you're supposed to pull to the side of the strip so you keep the majority of the liquids off the center of the track.
The second it blew you should have done that.
Exactly.
I love this channel, but they're playing a bit out of their league right now.
This is like Cooper who used to work with Cleetus. Big oil down guy
I never go to the track without the cooler packed with Gatorade/water just in case something like this happens so I'll have a nice cold peace offering! I've been lucky enough to not have to use it yet but I've been handed a couple Gatorades/waters and it always hits the spot. Awesome video man and don't sweat oiling down the lane because it happens and everyone is more concerned with you leaving in the same shape you arrived!👍👍👍
It sounded like it was on the max rpm. Good luck guys love the videos.
When going from gas to methanol or nitro you must increase the size of the orifice tube directly under the jet as well as the jet to run right. The other fuels like a little more timing too. You may already have this information, just checking. I like your videos, keep them coming.
Another great video. It was sad but so much was learned. Mr C has a heart full of concern for Ike. I too was worried he would catch some metal.
Grinding on the clutches.....great idea
Man that sucks to have a failure like that, I just took my home made turbo 125cc dirtbike out last weekend, makes me glad I have a clutch and and transmission and a torque converter. Also super cool to see my name on the firewall!
If you ever have a failure on the track like that again, pull to the side as soon as possible to minimize the amount of oil on the driving surface. It'll make people a little less mad at you when they see you make an effort to minimize the spill. A converter guard might be a good idea too lol.
We all knew I was risky with that tourq converter, you guys weren't sure it would hold up to the dyno session... glad nothing really major broke and Ike wasn't injured 🙃 I think gears might be the only way forward depending how much you want to push the motor...

Excellent camera footage, glad no was was hurt
Gotta love the arm chair quarterbacks in the comments right? You guys are smart enough to come up with something that will work. As long as you are driven by your desire to have fun your channel will still be cool. Thanks for the slow mo explosion bit, super cool!
I did some very rough calculations using estimations of the size of the exploded pulley, and given the rpm those flying chunks left the engine at approximately 200mph.......congrats on the new speed record! That's gotta be a record or something for the 1/8th mile
In FSAE the torque converter is required to be covered with a steel shield for this very reason. Would recommend TC scatter shields in the future. Also have a look at Microsquirt EFI. It would be so much better for controlling this setup. Would suggest using Gates Barricade fuel hose, a Walbro GSL393 fuel pump, and an aeromotive regulator with 4an fittings. Use LS ignition coils for spark, 550cc denso injectors for fuel. Use a crank trigger mounted between the drive pulley and the block and run wasted spark. From there you need a 30-40mm throttle body mounted after the turbo with TPS, a 3 bar map sensor, and an intake air temp sensor. A proper plenum will improve cylinder to cylinder distribution of air. For a 670cc engine a plenum with a volume of 1 gallon should be about right. Executed right that list of parts should get you to 100hp or more. Many FSAE teams achieve 70-90hp with similar parts on motorcycle engines breathing through an 18mm restrictor.
How refreshing, an automotive sport that you don't have to be a millionaire to participate in. This looks like some excellent fun! :)
Snowmobile clutches are generally a 30mm taper bore. A little fancy machining of a collar that goes on the motor is possible
You guys should swap to a rear differential and driveshaft. You can turn the motor 90° and make everything much safer in case the motor or clutch comes apart. If you do a quick change then final gear changes literally take a minute to do. You could run a torque converter setup like you are just instead of going to a jack shaft you turn the driveshaft for the differential. The other option is a transmission which would be pretty sweet but what to use I haven't any idea. I suppose you could literally make a flywheel clutch and mount up a manual transmission but you would need to have an adapter plate made to mount to that specific engine.
They already have 2 carts with shifters. Gears is the way I would like to see them go for sure
maybe they could do something with a transaxle out of an old Volkswagen
@@drunk_by_noon9231 I think front engine rear wheel drive would work the best with a V-Twin engine. If it were me I would go to the local scrap/junk yard and pick whatever they have the most of as it will be the cheapest and easiest to find.
With this much power, in addition to your other safety practices I think you guys would be well advised to always start the dragster with the rear end on blocks.
I’m just happy no one got hurt in that show that was bad ass and that’s how you do it…. I’m glade you have the people doing that damnit the way you all do shit is so bad ass keep it up … I’m getting a new cvt today… I hope we learn from this and move on with bigger and better parts you guys are the baddest there is I’m glade you didn’t blow the engine WOW nice job and Ike don’t be sorry shit happens you did a great job keeping that Monster on the track….
It could happen to anyone of you…. I can’t now but willing to help…. WOW nice… now rebuild and go again….
Love ya all and be careful… it could have fired up on ya…. I’m very impressed let’s do it again boys…..
Just got my Vote for turbo shirt and yall signed a piece of the belt for me. Thats very nice guys.
