Everybody should at least once in their lifetime see topfuel dragsters live, such an impressive experience! The power of the sound and shockwaves is something else and the technical aspects are absolutly crazy aswell! By the end of the run they completly melted their glowplugs and they are essentialy dieseling/its a runaway to the end of the run until fuel gets cut off, completly mindblowing :)
Note, turbos and 4v dohc is banned in top fuel. They could be much faster, but... many tracks in the us are too short now, even @ the shortened 1000', and the NHRA does not want them to go faster. If modern engine configuration was used, tf would be much faster.
If you want to try aluminum wheels, have the surface of the aluminum prepared with a knurling tool at the machine shop. However, I think I have a better idea. At work, we use a lot of urethane and epoxy for casting, and they are quite impressive. You could have an aluminum wheel machined with channels through the diameter of the wheels, then cast urethane around the wheel. This way, the tire would be mechanically locked to the wheel.
I get the feeling you're going to run into ballooning issues there, and I think, especially with how often the current tires are being completely destroyed, it's not going to be cost effective, I think the current technology needs to be refined and I think we need to stick with plastic wheels but design them so that their structure accounts for the crazy forces that their experiencing.
Top fuel is no joke. Those things are controlled explosions down a 1/4 mile. The first time I heard one my hands couldn't cover my ears fast enough. Power!
I'm glad you are at the pod and giving it the recognition it deserves, if you live in the UK and you have never been, i 100 % recommend it, it's 100 % family orientated, it's an experience you'll never forget, just don't forget your ear defenders,
We need on-board footage of these speed runs. It would be epic! Also a good way for research on what all the components are going through at these speeds
Insta 360 is small and clear enough yo do it now. Camera technology has definitely gotten better since gopro came out. You couldn't fit those in small spaces.
Loved the ride with Terry. He sure manages to keep a loose relation between the 'front of the car' and 'direction the car is traveling'. And all during a friendly chat. Impressive.
Maybe the diff blow was due to the sticky part of the road, all that 100hp was put through the diff as the wheels were locked to the road from the sticky road, maybe usually the wheels spin up a bit on normal tarmac and takes strain off the diff. love the vids!
I am almost 100% sure that the problem was too much traction, all the power suddenly went to the drive shaft which simply couldn't handle it. Under normal conditions, the wheels would spin and the power from the engines would be distributed. It's one thing to withstand the power transmission at high speed, and another thing to withstand the power at the start, especially from the electric motor which provides full torque from the very beginning. The cause of the car jumping is also too much grip, this is what a wheel behaves when it has too much grip.
I am not sure if anyone else has covered this in the comments....but I have watched hundreds of drag racing videos from Santapod. That track as wonderful as it is for full-size cars has a fine 'washboard' surface undulation in the prepped section. I have noticed it many times when watching short wheelbase drag cars, such as Karts with bike motors. They hop about fiercely. In your video, at 21:18 you can see that washboard quite clearly. Great videos. Great fun. Please keep up the super work.
Here in the states we use aluminium rims with proper (albeit tiny) steel belt tyres. They are filled with foam but its the only way to keep things from exploding like that.
I think you are pretty on point at what happened when you lost drive. The dragstrip is so sticky that when the car hopped it sent massive shocks through the drive line every time the car landed. It's amazing that a dragstrip is still not smooth enough for a perfect top speed run! They feel like glass in a car!
My uncles got a 1500-2000hp suppercharged outlaw car. It's awesome only thing is the motors don't stay together. 😂 fastest she has ran is a 6.90 on the "big engine" winsor and runs 7.36's with the clevo. I absolutely love working on it. Hasn't been together for 7 months becuse we have been waiting on piston sleeves and after that pistons then measure gaps and put it together
Hey, One way to solve the problem with the exploding tires would be to increase their diameter. The centrifugal force that lets them explode decreases exponentially with increasing size (at the same speed of the car!!). In other words, the tires would tend to explode way, way less by increasing their diameter by only a small amount, even if the car is driving at the same speed. And the smaller the tire, the bigger the gain with small changes, so it's especially applicable to the rc world. Decreasing the mass of the tire would decrease the centrifugal force too, but changing the diameter has a bigger impact (because of squared values in the formulas). Of course, the gearing would have to change according to the new tire size.
Standing by the starting line as a top fuel car takes off is an experience. I'd suggest doing it at least once. Fun Fact: Top Fuel cars idle at 100+mph.
I think that glued section of the quarter mile is the car killer. I would run them from the other end of the track and use the glued section as part of the breaking area. Also that wind was like gale force it’s too bad the driving conditions weren’t a bit better. I think that must have been filmed in the summer right?
It's a good thing they didn't go the opposite way! 2 cars already overran the track... they would have hit the building and not been invited back. Think about when these cars blow out the tires before hitting the prepped surface... Better to hit dirt than a building / flat wall.
I know very little about RC cars but seeing how the wheels are like a "sponge" material I feel like the glue just rips the tyres off their rims, it's just too sticky.
Although the surface seems completely flat, it isn’t. Nothing is. IMHO, either use higher profile foam tyres, or install shocks. The car needs something to absorb the surface’s irregularities. At that speed, any tiny bump is magnified tremendously. That’s why it hops. Nice job. Keep on pushing!
Would love to see some data logging on the normal tarmac vs the sticky tarmac on the drag strip!!! Thinking the amps and voltage drop will be massively higher on the drag strip⚠️⚡️🪫🔥 Kev please make some testing on it🙏🏻 Would really love to se how much more the setups sweat on that strip!! Thanks for the video😊
My suggestion if you are going to try a special wheel is to go to a skateboard wheel manufacturer and see if they will help you. They make hard to soft compound wheels and everything in between. I would think that a solid compound wheel would solve your problem of the rubber de laminating and the rim failing. Won't hurt to try good luck
225mph is around 100m/s, so now divide per 4 to get the acceleration, u get 25 m/s². One g is around 10m/s², so this basically accelerate in average from 0 to 225mph with 2.5g force. That's crazy knowing that a standard scale 1 car accelerate at around 0.3g.
Hi Kevin if you would increase tier radius the centripetal forces in the wheel drum would decrease, (f=m(v^2)/r). Maybe line the periphery of the rotating surface with uni directional carbon fiber band and epoxi and then put on the foam / rubber. Great content by the way.
I would try aluminium wheels with perforations on the road surface, then set into a mold allowing the foam to pass through the perforations from the road surface into the inside of the rim. Would be difficult to setup, but once done the foam no longer needs to be bonded to the wheel.
Been there in May watching them, they really have to be seen to be appreciated. They actually register about 2.4 on the earthquake ricter scale! Awesome spot to get behind the Xmas tree too, top stuff 👍
Great video. Soo cool you guys got to run there at santa pod. Hated seeing all of the carnage though. Im a speed runner myself soo I know how crashes can be heartbreaking. My PB is 155mph soo far with an open wheel Limitless and 2028 1700kv w/ xlx2. Its all Scorched out too! Awesome parts!
@@KevinTalbotTV thanks man. Those 2028 1700s are no joke. Kinda hooked on speed running now. Im gonna turn my infraction into a GT speed car. A hobao is on my list too!
I watch a ton of car content, so its fun to watch ya have a blast inside the stunt cars and stuff. Imagine drifting like that but at 70mph downhill lol!
The move to larger diameter wheels is certainly a good idea. While they require more initial torque, larger diameter wheels can sustain much higher speeds.
Love the video Kev! A couple observations... Your car definitely looks too heavy for plastic wheels at those speeds and loads. Carbon fiber or aluminum wheels do sound in order. Perhaps you can afix a plastic ring outside the circumference of an aluminum wheel, then glue the rubber/foam to that plastic? The solid link instead of a spring and shock is certainly where the wear and tear on your suspension arm joints is coming from. If the arm can't pivot, it's going to try and move somewhere, and those pivots looked to be the weakest link. Perhaps go for a very strong spring and use bump-stops to prevent travel going too far. A suggestion for stopping the cars when you lose driveline or tires: rig a parachute system on another radio channel. It's how the big boys do it!
A buddy of mine went to see top fuel races and I kept telling him and showing him videos about how nasty they are but yeah until you see em live it can't be described. He called me after the first run and was mind blown. He said man you told me over and over but he didn't even begin to grasp the immense raw power. It's legit like a bomb going off. One cylinder makes more power than most super cars. Heck they idle with more power than most passenger cars, and even some sports cars. Absolutely bananas
Of course we love our Mad Max! Show me a man who isn't oddly satisfied by things being destroyed in a creative manner.. like the disk of ice from a vat of water hitting the ground perfectly parallel, a car getting impaled with a large steel dart or basically anything getting squeezed to death by a hydraulic press - there are entire channels, with two-digit millions of viewers, dedicated to that. 😆
If you scuff the aluminum pretty good I bet you could get a good bond. The biggest problem seems to be the foam needs tweaked to be stronger or more dense. Hopefully a rc tire company will come up with a better high-speed compound
Awesome video as usual been to santa pod a couple of times when in the UK every petrol head should visit at least once in a lifetime you have to feel it to believe it brings back good memories typical u k weather though rained for the whole 3 months I was there end 2019/20
I absolutely think the reason you are getting the bounce is because of the prepped track surface. Same thing happens to real cars when they have too much grip, it’s called wheel hop. Wreaks havoc on the driveline parts. Those little cars with all that power need to be able to have a little bit of wheel spin, I would think. Especially when accelerating early in the run.
No such thing as too much traction in drag racing. Wheel hop is caused by the driven wheels pushing forward and losing traction. On an IRS setup you see an increases in toe angle which causes the wheels to slip. Once the traction is off they snap back to their normal position, bite back in, slam forward again, rinse, repeat. It happens on live (solid) rear axles when the whole diff assembly rolls forward, compressing the lower trailing arm bushings to a point where they cannot move anymore. The sudden bump as the diff hits limits causes it to break traction, which allows the diff to fall back, wheels to bite back in, push forward again, also rinse, also repeat. The answer is always a stiffer bushing in your lower control arms (IRS) or sturdier trailing arms for live axle racers. Considering the twist visible in the lower control arms at the end of the video this is almost certainly whats happening. I would be putting a solid control arm at the front instead of a damper as Kev speculated. Hopefully he'll have a look at some drag car info for advice.
100% that's why. The prepped surface helps with traction but it also prevents the wheels from rotating by increasing rolling resistance and since it isn't consistent, you get wheel hop.
If you look at slowmotion video of racecars and dragster tires. The rubber tires have loads of flex so much you can see the wrinkle in slowmo on launch and match that with their suspension travel. Id say thats what keeps them from hopping on that prepped surface. The RC not having any suspension or flex at the wheels to absorb all that torque on such a sticky surface. It makes you wonder your wheels arent the issue of why they keep failing but maybe finding the proper surface to account for the wheel spin. Also having a lengthy run up to gradually build up the speed so all the G force isn't put on the wheel/tire so quickly just tearing it apart or so your not giving it the chance to spin the tires and make them blow out that way. But im just kind of shooting in the dark. Im not an expert and im not sure if all that makes any sense but yeah.
WOW! what an awesome experience!!!! so many different fun things happening!!! M2C 6 LUG HUBS MADE IT THRU!!!! btw, now you know what your infraction feels like!!!! Keep it up you'll hit the goal!!!!
That was sooo badass either way!!! The fact that you can build that like that is amazing to me!!!! I have a success Arrma Kraton, a Vee five and I think I’m awesome because I can kind of work on it! 🤣🤣
Unless your front and rear wheels are spinning at exactly the same speed you are going to hop on a surface that is super sticky. I'll bet that the single engine rear wheel drive cars didn't hop as much.
Absolutely epic! Santa pod is definitely the place for speed! Had me worried with that prep though! The base of the rc was never meant to see that weight/power and traction!Definitely a good idea with the shock’s Too! If it’s possible on those arms To limit torsional unloading of the control arms a pair of shocks per arm at the front and back of the tower will help reduce tramp and help keep dampen those vibrations when peeling the tyres also at that power and weight an extra trailing link or link’s from the rear of the chassis to the leading edge of the lower control arm or both will also reduce the unloading, I’d suggest going back to springs but source some seriously heavy wire! perhaps small engine valve springs or similar with heavy shock oil to suit,And for the wheels I’d go carbon fibre! the only wheels that stay on the front of my rwd speed run car are carbon/foam! It’s 1/8th scale rear drive but with a 1/10th front end, so the little wheels are properly spinning! Plastic wheels just expand or explode!
Went to japshow finale last Sunday at Santa pod with square society. You definitely went faster than my friends in their nissan cubes. Best was 18.8s at 72mph 😂😂😂 life's too short to be normal. Great video.x
Kev have you ever considered fitting a VR camera and use a live view VR goggles for these speed runs? The reason I suggest this is because one of the big issues you speed runners seem to face is keeping the cars running straight as possible, as they become tiny in the distance and very difficult to see and "feel" what the cars are doing, because you aren't actually "in the car" so to speak? Also, I would suggest you do more work to cover the front wheels atleast, because those open wheel arches are causing all kinds of air turbulence and subsequent instability of the vehicle? I sincerely hope you get this record eventually, you've really put everything into that car, it's super impressive.
Greatest RC content on UA-cam by far! Thanks for all the hard work Kevin CHEERS MATE! Love your channel from Washington State!!!!👍🏼👍🏼👍🏼👍🏼🔥🔥🔥🔥🔥💯💯💯💯💯😀😀😀😀😀🇺🇸
You got ear plugs in and “ears” on and it’s still loud AF. The camera does not do it justice but I know what it feels like and your expression is priceless Kevin. Especially when it caught you off guard…🫶🫶🫶
Kevin, you should come to the states for World Cup this year for dragracing, youd really enjoy it. Street cars going 6 seconds in the quarter mile. Its nuts.
Fun Fact: These dragsters are so loud and thundering that if it was measured on the Richter Scale, it would the equivalent of a 3.2 magnitude earthquake! 🤯
Just found your channel, very impressed, lots of great content to binge on. hope you manage to sort out the tyres and get the record Kevin, can't wait to see the next episode in this series, that's some seriously impressive engineering and knowledge.

Yup. Buying a Suzuki Cappuccino soon. Just saved up about enough for it so i'm going to be checking out some auctions. 63hp at 1550lbs.
Indeed, my last stationwagon before my current one had 100hp 😆
My current daily is a 72 220d with 59 hp.
Maybe he can use it as a skateboard..
Isn't the same
I have always loved drag racing, I grew up around it. I even travelled with NHRA for about 5 years. And I will never stop loving drag racing.
Maybe the diff blow was due to the sticky part of the road, all that 100hp was put through the diff as the wheels were locked to the road from the sticky road, maybe usually the wheels spin up a bit on normal tarmac and takes strain off the diff.

@@KevinTalbotTV no, just stay off the prepped surface, it's also weakening your foam.
If you look at slowmotion video of racecars and dragster tires. The rubber tires have loads of flex so much you can see the wrinkle in slowmo on launch and match that with their suspension travel. Id say thats what keeps them from hopping on that prepped surface. The RC not having any suspension or flex at the wheels to absorb all that torque on such a sticky surface. It makes you wonder your wheels arent the issue of why they keep failing but maybe finding the proper surface to account for the wheel spin. Also having a lengthy run up to gradually build up the speed so all the G force isn't put on the wheel/tire so quickly just tearing it apart or so your not giving it the chance to spin the tires and make them blow out that way. But im just kind of shooting in the dark. Im not an expert and im not sure if all that makes any sense but yeah.
This man is keeping my bank account empty. Thanks kev 😂
WOW! what an awesome experience!!!! so many different fun things happening!!! M2C 6 LUG HUBS MADE IT THRU!!!! btw, now you know what your infraction feels like!!!! Keep it up you'll hit the goal!!!!
Who let Max out of daycare? Boy follows Kevin around like a lost pup
salty boy jealous you dont have any cool friends
That was sooo badass either way!!! The fact that you can build that like that is amazing to me!!!! I have a success Arrma Kraton, a Vee five and I think I’m awesome because I can kind of work on it! 🤣🤣
Unless your front and rear wheels are spinning at exactly the same speed you are going to hop on a surface that is super sticky. I'll bet that the single engine rear wheel drive cars didn't hop as much.
Absolutely epic! Santa pod is definitely the place for speed! Had me worried with that prep though! The base of the rc was never meant to see that weight/power and traction!Definitely a good idea with the shock’s Too! If it’s possible on those arms To limit torsional unloading of the control arms a pair of shocks per arm at the front and back of the tower will help reduce tramp and help keep dampen those vibrations when peeling the tyres also at that power and weight an extra trailing link or link’s from the rear of the chassis to the leading edge of the lower control arm or both will also reduce the unloading, I’d suggest going back to springs but source some seriously heavy wire! perhaps small engine valve springs or similar with heavy shock oil to suit,And for the wheels I’d go carbon fibre! the only wheels that stay on the front of my rwd speed run car are carbon/foam! It’s 1/8th scale rear drive but with a 1/10th front end, so the little wheels are properly spinning! Plastic wheels just expand or explode!
Is way too heavy bro
It has 100 hp the weight don’t mean shit
Errinnt mich an Richard Hammond der gute Mann. Stabiler Bastler, danke für die wilden Videos
I think it was the sticky surface making the cars 'judder'.
I'm with Max all the way! Takes someone special to find the limit! Kev simply searches for it.
16:28 Never thought I'd hear an RC car sound like a spooky ghost lol
Seen that last vid… of you asking about other content…. & then this….Stick with it dude…!!
This is the why you got where you are….👍
Epic video.. I ❤drag racing the feeling u get when they take off. The Best is doing it yourself.
7:05 "whats goen on?!"😂❤
car on the tires🔥 8:34
love drag racing, havnt been to santa pod for years, all ways had a great time their.
16:48 I have been activated 😳 Very cool video, Kev! I love the sausage! I really think if you get those tires figured out, you will get that record 👍
Finally a new video for this car 🙏🏻
WHAT A FANTASTIC VID.
LOVING IT.!
Love this video mate. Keep going. Your determination to get that record has to pay off soon!!
I love it on that track...❤😂
Whatttt. I can’t believe you don’t have metal diff cases and metal internals or rally diff lockers
Traction control. Nice power curve. 👌
Went to japshow finale last Sunday at Santa pod with square society. You definitely went faster than my friends in their nissan cubes. Best was 18.8s at 72mph 😂😂😂 life's too short to be normal. Great video.x
Metal rims with neoprene or urethane wheels may be more suitable. Skate boards use them very effectively...
Dunlop, McGuiness, Martin AND Talbot? IOM going to get crowded with superstars 🇮🇲 🇺🇸
Kev, I was thinking you guys should run mini drag chutes. Would save everyone!
Glad you got to experience Santa Pod kev spent a weekend there once myself with a pit pass 😉
Awesome video!!!! Happy RC’ing Y’all!!
Kev have you ever considered fitting a VR camera and use a live view VR goggles for these speed runs? The reason I suggest this is because one of the big issues you speed runners seem to face is keeping the cars running straight as possible, as they become tiny in the distance and very difficult to see and "feel" what the cars are doing, because you aren't actually "in the car" so to speak? Also, I would suggest you do more work to cover the front wheels atleast, because those open wheel arches are causing all kinds of air turbulence and subsequent instability of the vehicle? I sincerely hope you get this record eventually, you've really put everything into that car, it's super impressive.
You now need to get the record!
Absolutely fantastic day out and Thank you 🙏 again to Santa Pod & Yourself Kev 🦾
yes mate!! epic day thanks for joining us
The percussion from a Top Fuel Car off the line definitely stands you in place!
Race tracks are finally getting smart and bringing in influencers to help promote the track.
And this is why I love drag racing
I like track racing so much more than a thing just going in a straight line and after 4 seconds the run is over. But to each their own :)
I absolutely love this series!
Good to see the free loader is there again . Even rc mann has clocked max and his agenda
Love max, he's the best
Just outstanding…. Brilliant.😎🔥
Greatest RC content on UA-cam by far! Thanks for all the hard work Kevin CHEERS MATE! Love your channel from Washington State!!!!👍🏼👍🏼👍🏼👍🏼🔥🔥🔥🔥🔥💯💯💯💯💯😀😀😀😀😀🇺🇸
You got ear plugs in and “ears” on and it’s still loud AF. The camera does not do it justice but I know what it feels like and your expression is priceless Kevin. Especially when it caught you off guard…🫶🫶🫶
I'd love to see Kev build a drag car - maybe not jump into top fuel/funny cars but maybe Super Comp or Street Eliminator
omg i was thinking the same. maybe pro alcohol. we know he wants a loud car haha.
Kevin, you should come to the states for World Cup this year for dragracing, youd really enjoy it. Street cars going 6 seconds in the quarter mile. Its nuts.
Classic Talbot driving
It would be cool if your group of speed runners could put on an exhibition intro as part of the actual show! 💡
that would be fun!
Fun Fact: These dragsters are so loud and thundering that if it was measured on the Richter Scale, it would the equivalent of a 3.2 magnitude earthquake! 🤯
All right, Kevin! Thank you so much for posting this we have all been waiting!
Just found your channel, very impressed, lots of great content to binge on. hope you manage to sort out the tyres and get the record Kevin, can't wait to see the next episode in this series, that's some seriously impressive engineering and knowledge.
I can see the world's Best Truck in the Background and Love the colour
Glad my cousin Terry gave you a good ride 🤣🤣 he is a nutter 🤣🤣
