- Follow along as I try and save a 10,000 hp producing 1471 supercharger. This video shows you how to re-strip a supercharger used in top fuel drag racing. This shows the technical side of rebuilding and saving a supercharger that others might throw away. This covers about 40% of what it takes to build in-service topfuel 10,000 hp Supercharger. There are so many steps in rebuilding one of these and little by little we will show you how it’s done!
Finally! Now I know what to do when I buy my 10 000hp blower, thank you!
Your welcome. 🤣
🙄 never heard a joke like this before…
I like that PROFESSIONAL description of the high-performance material "what we call PLASTIC!"...lol! Hahaha
🤣🤣
This is so cool! In a world that considers everything a consumable, it's nice to see someone putting in work to save something. It's a lost art.
Throw away Society!!!!
a grass roots effort called right to repair or fight to repair is brewing
@@cdoublejj Yup were all sick of throw away crap and a $1.50 part we cant buy because of whatever corp. So we get to buy another $1k whatever again... Total BS.
In a world of JIT manufacturing, near zero tolerance, and material cost optimization it's nearly impossible to appease both ends of the spectrum.
Make it durable enough to last forever ($$$$), or make it efficiently as possible to get the job done until the next model comes out ($).
Unfortunately, the only thing that hasn't changed is the price to consumers.
@@johnspurrier0001 I'd rather rspend more. People always chase the cheapest price. No wonder the US economy has been in the crapper for 50 years!
This is a lost art that needs to be passed down. Thanks Rob
Holy hell the size of this beast is a monstrosity
It’s a big bitch! 🤣
That's what she said
@@robwendland I’ve had to say that a few times in my life😂
There are even bigger ones in industry applications like vacuum pumps
Seeing those end pieces I now see how fidget spinners where discovered 😄
Good one!
Cool video did not know this was done.
Beautiful. It still astonishes me that 10,000 HP can be pulled out of An engine.
It’s nuts. Shit doesn’t last very long for sure!
@@robwendland Isn't it, a rebuild after each run, and a complete new motor after 10-12 runs? 2 miles per engine 😆
I saw a video a while back of a top fuel injector for a single cylinder running in a visual display. It literally looked like Andre the giant was giving a bare hug to a 5 gallon gas can.
Edit, I found the video.

@@BryceAWD Every part on a front running Top Fuel teams car has run count limit if it was not FUBARed during a run
That blower takes about 900hp from the crankshaft at 8500rpm. Wrap your head around that, next consider nitromethane/10% methanol burns with 1 part fuel to 1.7 part air and the whole thing runs on the verge of hydrolocking. The flames coming out the exhaust? Oh thats the cooling system....
@@richardturner8630 The whole thing is an absolute marvel of mechanical engineering.
Dude! You’re SO good at explaining how things work and what you’re doing. Awesome video!
Thank you!
This is absolutely amazing. I was well aware the plastics had to be changed from time to time but I had no idea what all was involved in getting it right. Love this!!!
DEFINITELY not long winded!! LOVE this stuff! seeing PSI, vs. JFR, etc. is really cool (and JFR, or Prock anyway, have the guys restrip EVERY pass is crazy) -- back about 8-10 years back. 🤘🏻🤙🏼😊
They still do!
@@robwendland I remember how happy the supercharger guys were when another car went out during eliminations...because one of the guys could come do one of the two rotors for them, haha
Rob, you're a true craftsman. Thanks for sharing this with us. Great lessons like these are dieing every day.
Thanks for watching!
Love this stuff. So damn interesting and I just have so much respect for your craftsmanship and absolute knowledge. I make it a point to enjoy the hell out of men of knowledge like you because as with everything you work on you are finite as well and the day will come when no more men like you exist. Only machines.
Thanks for the kind words I truly appreciate it
Great video!
Now that is your old school hot-rod talent. I hate throwing high end equipment on the scrap pile just because it’s got a little ding on it.
Good save.
Thank you!
Some of us pull from the scrap piles, but just wish folks would throw things into it more gently, LOL...
Im liking how you know when my little bit of freetime is....
Facts!!
Bro, I know just how you feel! I installed a cold air intake on my Honda Civic and the box said I’ll get “up to” 15hp and…. yeah… I’d say that’s true! 🤓
Since those blowers aren’t exactly cheap, I’m sure the work you put into saving these components doesn’t go unappreciated since it probably helps the race teams save a good bit of money versus having to put a brand new blower on their engine.
Stuff like this is what makes TH-cam awesome. I'll never need to rebuild a top fuel blower but I enjoyed every second of this informative video. Great job. Thanks for posting!
Why not just rebore the case to give more clearance for the strips and to make it true again?
It’s actually bored like a football somewhat. Along with the tight spot, there are loose ones on the wrong areas. Say 4 and 8 o’clock. Rebooting the case is possible but a 5 hour process and it there’s a possibility it won’t be any better than it was.
I was thinking the same, even maybe lapping it with a custom lap to make it deadnuts and perfect along the length
@bcbloc02 havent seen a barn shop update from ya in a while ;-)
Why do Americans say "maysure" and "heighth"? Stop making up words! There's already words for those!
I stumbled across your videos a couple days ago and I can not stop watching. I love understanding the fine details of how they work, including tools used. Love the videos and keep them coming.
Thank you!!
That was awesome. I'm a new subscriber. I'm going to be going through all your video's. Thank you.
Thanks for watching brother!
Instead of "How It's Made" they should make "How It's Maintained". You don't really think about this kind of maintenance on things until you get a random TH-cam recommendation. Very well constructed video, informational and top notch commentary.
Thank you for the kind words!! Really appreciate it!
My good man I believe that "clover leaf" is called a fidget spinner (for the dense ones I'm joking)
Lol 10,000hp fidget spinners lolol
Exactly what size is the supercharger? Maybe 14-71 or bigger?
Is this one of the jobs Drew Mitchell did for the team a few years ago? I know Drew from racing with him locally.
It sure is I sure miss Drew!
Thanks - I had never seen inside a super charger before.
Wouldn't it be good to test it while running even at say 1000 rpm?
I knew my 2006 Honda Accord coupe was missing something
Man you have the coolest job!
This is such cool information! Thanks for sharing this!
Thanks fir watching!!
The first shop I worked at was right off the Mississippi and we'd get engine work from the workhorses pushing barges. We spray welded the shaft to build up and turn down and it too was from a 10,000hp blower, except the lobes of this guy were about 18" in diameter. It was a sight watching that huge part spin with a madman wearing torch glasses blowing a three foot flame into the fucking thing.
I sure would’ve loved to of seen that !
Man, working on these cars is my dream job. Thanks for sharing!
It seems like after rebuild the blower still takes quite a bit of force to turn, my question is; what kind of hp does a blower like this take away from the block to turn? I understand it overcomes the loss but there has to be some accessory loss from the pulley, right? Great video!
400 hp!
Still bet it will make some serious hourse power lol. Thnks Rob for sharing.
It will, just a couple of percent of overdrive more
That blower had been blown before maybe?......that's how most get raised centers
100%
I seen blowers were the wipers are gone.. They sold it for nothing...They thought it was trash...
Send them my way
Hey rob, could a bit psychotic guy like myself be able to do this with an eaton m62? just changing the eurethrane and cleaning it up.
that machine, i cant afford 1 of those though lol
cleaning up after yourself aint all that bad!
Very interesting. 10k hp is insane especially out of such a small engine. I wonder what one of those giant Caterpillar 3616's or whatever would produce if fed nitro at a rate comparable to the engine size. Of course you would need probably 12" feed lines to push that much nitro and a 2000hp engine running the fuel pumps.
We would have to shorten up the stroke a bit. It would be a great video....😜
@@robwendland It would be exciting that's for sure.
I'm 50 years old ... And I would love to be your apprentice....
That means a lot! Thank you!
that case has probably seem a few "back-fires"..... and thats why its all "bent" out of shape
Even in the shut off. Just a little sneeze.
Do blowers run any type of lubrication. Is that what they pour in the blower on start up from that small bottle?
They are starting on gas. The fuel is the lube.
just a question from the outside looking in but where those rotors are worn . does that not create an efficiency loss ? or does the urethane striping just take all that up ? or on the other side of that are you just not concerned with a slight loss due to the change out of blowers etc ?
They definitely are worn but that’s also an indication that the lobe size is not too small which a larger lobe size tends to be a better blower
Always interesting to see how other guys do this. My blower jig is at least 30 years old and I torque the case down to get that distortion out. Kinda like using a torque plate when machining a block, then you know if it's flat, then I check the manifold too. It's a bit of a forgotten check since we all use o rings to seal the blower to the manifold. I love the seal machining jig, I still machine them in the lathe. Had some shocking cases that had to have the rotors taper turned to get correct clearance front to back. That was a pretty nice blower to start with (I never get the nice ones!). Had a couple that had some big bangs go through them that needed all the clearances done and re dowel the front and rear plates, re pin the rotors, new shafts, the works. Cool video Rob, keep em coming.
You get it for sure! Getting end frames at the right height can be a real workout. This case never was bored correctly. We do check the manifold when it is bolted on the car. Make sure the blower is flat also. I taped cut the rotors bigger to the back. Just add a shim under the front bearing on the cutter jig and rip it across!
Graphite is best to see high spots just like a dentist uses when you do bight checks on paper .
Good idea ‘nb
never saw the inside of a blower before. awesome and thanks!
You bet!
Man i like the info and all...but the ____10000hp tag is stale as balls.
Next one will be 10,001 then
No wonder everyone rebuilds turbos this shit takes too long
🤣🤣
Is the blower bolted down to your fixture as if it was to the manifold, or is that not an issue?
Manifold should be flat like the blower. Yes it does matter!
Lol, 2 Rob's on TH-cam talking about rotors!
Wait?! What?
May be long winded... but very interesting. Thanks
Could of been 45 minutes easy
Checking in before this channel hits the moon. Just got recommended to me-you know what that means
You videos are awsome. I am learning alot!
Appreciate it brother!
Do you use ceramic bearmiings on your blowers ?
We do not. I don’t think ceramic bearings take impact very well do they?
Great stuff
So not in a top ten on the NHRA circuit ... so what application would use this blower?
3.80 car. No problem!
Hey Rob, How many of those Lightweight DZUS FASTENERS do you have attached on the lower & upper rails? [Believe it or not -I’ve actually got 50 of them in 1:25 scale made in PhotoEtch] 👉This Video is the 1st time I’ve seen them in place on a bare frame, but couldn’t make out how many total there were….??
Thanks You 🙏 Sir for another Excellent Instructional Video for Top Fuel👏👏👏
Lee
aka: ☯️ZenModeling☯️
Great video Rob. Really want to put a blower back on my car now. Those things just suck you back into them....
I'll be here all week folks 😋
You don't check the runout of the lobe to the centerline of shaft bearing OD's?
Wow! Cool stuff! Do you ever have to check or set end play in the rotors or gears? Or would that only be if you were installing new rotors? Very interesting information. More please... Hahaha
Why not use a turbo. So easy to maintain.
Because the class requires a roots style blower....
Some spring action in the channel to push the seal into tension against the case would be nice.
At that rotor speed, too much friction! Melts!
@@robwendland Thanks for the reply. I don't know how the mechanics of it would work but if the polyurethane survives I don't understand how spring tensioner behind them would melt.
This is awesome. We hear the word supercharger all the time, but I'm only an engineer, so it's good to see what it's all about.
Awesome vid,I never knew they had replaceable seals on the rotors,last time I saw inside a blower I was a kid and didn,t pay too much attention,I always thought they were metal on metal even though I knew that would be harsh,and I had never thought about the ID seals either,so I,ve learnt a lot in the last 15 minutes,and even though I,ve put a few chev and fords smallblocks together,installed cams,valves,timing and everything else to do with engines,clutches and gearboxes,I've never had anything to do with supercharges,so thankyou for showing us and for the commentary and explanations and visuals. Awesome. Best wishes from,Auckland,New Zealand ⭐⭐⭐⭐⭐👍👍👍👍👍💯🙂🙂😉😉
This takes me back in time to where I was working in Bill Miller's shop making cases from sand castings, and the rest from billet. Setting the timing and pinning the 2-peace gears and pinning the bearing plates to the cases always took forever. It was cool to see one you made from scratch come back in for a rebuild and get it it back in a box, headed out for more track time. Just curious, why don't you turn down your OD plastic on a lathe?
We use to back in the day. The plastic changed and a lathe cut almost melts it now.
@@robwendland No kidding? We were using nylatron back then, warming it up in an oven before pulling it in the grove and capturing it with 10/32 socket head screws.
Oh it's like an apex seal kinda? I've seen small rotary engines and that's all I could think of. New subscriber here, started with building small engines (lawnmowers, miniature pulling tractors) I work on passenger vehicles now. My neighbor has a late model for the dirt track and when I saw his dry sump I needed to know more. I know Top Fuel is way different but man, you've answered so many questions I've had so far, especially about the rear end... I knew those things had to be SUPER narrow. Thanks for the videos, I enjoy every minute of them
Wish i could learn more about blown setups! Im a nitrous guy that wants to convert
Would have been much more pleasant without the background music...really detracts
Very interesting video thanks
Thanks for watching!
You don’t have any young folks helping you and learning these very specific skills? That is not ideal. The machining that went into the F1’s that powered Apollo can’t be duplicated by anyone today cause no one passed those skills and no one dedicated his/her self to learning.
Also, it seems a CMM with a high quality scanning head could be very helpful.
It don't look that big kinda small
Sure
I am so glad I clicked on your 11000 hp block repair video..I have watched 3 of them and had to suscribe right away..this is good stuff !
First of all I would like to say big in the fabrication industry my whole life with wood metal and everything in between I'm in my 50s it's a pleasure to it's a pleasure to watch you. Kind of funny I was the first person to go to Frank Holly's drag racing school from the West Coast when the school opened up its original year. My my phone right now but I'm going to get in touch with you I might have a project you might be interested in I don't know can't be told no unless you ask I've learned that after all my years of working. Be in touch soon hope you have a great weekend
That OD cutter is awesome!
Right?! Badass!
Good job teaching🙏
Appreciate it!
Hey Rob. Why did you stop using nylatron? Is it a softer durometer urethane providing more conformity and perhaps a bit more forgiving?
I use nylatron on the end frames. Tougher stuff. The urethane is softer but it does burn up easier. So it creates a little better seal
I guess impregnated Delrin would be way too stiff?
Delrin AF is definitely good stuff
Nice breakdown of the process. It's not an issue to have maybe residual abrasive embedded in the urethane after you debur it? Back in the 1970s I worked with an older machinist who thought it was funny to tell the new guys to "restore" their worn windshield wipers with some abrasive. When some poor fool fell for it he destroyed his windshield because the soft material retained abrasive. But looking at the insides of that case, it looks like it's been eating bits of pavement kicked up by tires on the lead car. So maybe it doesn't matter.
I’m lovin this
Thanks for watching!
Good work, I enjoyed the video
Thanks for watching!
I wonder if one of these would help to keep my lawn tractor from bogging down in heavy grass? If I miss mowing day by just 2 days it really increases my time time on the back yard.
Anybody here seen the new engine Masters where they put a blower on a giant tunnel ram and was making over 1,000 horsepower over a thousand torque at like 7 PSI
Wow, this was extremely interesting and informative. Good video, and good work!
Appreciate it!
Rebuilding a blower for guy guy who doesn’t want to win 🤷♂️
Just found your channel. Good stuff! Well spoken and you clearly explain what youre doing
Great video!! Very instructive and very interesting!! Nice job!!
Why can't you put the rotor in a lathe and turn the exact diameter you want?
Although that tool thingy is really kool --
Thanks for these videos keep um coming
What I missed, how did you adjust the Clearence between the Rotor lobes with the timing gear.?
I want to bolt this into my prelude sh with 330,xxx miles. Any supporting mod suggestions?
I’ve been around industrial blowers I work at a flour mill. The mill and grain elevator has blowers to blow the product around the plant site. I have rebuilt them the rebuild usually consists of bearings and seals on the end plates and new rotors
Are they mostly screw style blowers?
Stork Marel use similar seals for de fattening chicken hearts in poultry processing.
Can you actually prove 10000 hp
Yes I will try and steal the video for at least give you the link to a test session that was done with a Cupler that was built for testing torque and horsepower
That gauge you set to read the depth would be a much better trimming tool than that jig if it had a motor attached to it. You could run it across by hand and have exact depth set. Instead of spining a spine on a lathe. Much like a hand planner if that makes sense
Do you think it would fit on my mini?
Yes!
@@robwendland alright, 10,000hp supercharger video coming soon!
@@kingmercyful7975 note, he didnt say anything about it working...
@@onedayiwillmakesomecontent not with that attitude it won’t lol
It is crazy that that is the most efficient way to blow air into an engine, you would think something like a fan blade or turbine from a traditional blower would be the best way. Pretty cool somebody figured that out
I built blowers for 671s way back when and understand the headache of setting gaps. THANK YOU SIR FOR REFRESHING MY PAST!!!
You bet! Thanks for watching!
now i know why pro chargers are so popular, i thought the seals would be centrifugal seal instead of a pressure seal, now i see why they require so much power to turn, interesting.
Excellent doc on procedure and tech... would love to build a cutter for use in the shop/build room!!! Thank you for the upper echelon's r&r.... Seth
Do y’all build roots superchargers with a empty case?
Could you run a bit more fuel at the hat to seal up and cool those heated strips ? Great job. I am so glad I found your Channel. Take care.
Great video, really puts a lot into perspective. 👍
Rob, when did mfg's start building them with the plastic strips?
You said there should be more plastic sticking up on the rotor. But didn't YOU cut it down? Did you cut it too low?
Great info, the second I pondered what the seals were made of, you said it.
Thanks for sharing this!
