- Follow along as I show you the ends and outs of installing a 10,000 hp blower belt and getting as much life as you can out of it! Not only does this work for nitro powered machines but it also works for alcohol dragsters,funny cars, tractor pullers, it doesn’t matter, if it has a blower belt this will help! 
I love the friendly, info-packed, no bulls**t, clear and, concise style here.
I'm impressed with the nonstop tips in this one. Years in shared for free. You make this niche corner of UA-cam shine brother.
Agree
Sure appreciate that man!!!
@@SanjanaRanasingha this guy is just a national treasure for drag racing. To think that he cut his teeth working under the brain trust of Austin Coil and Bernie Fedderly. That would be like if Biden were to cut his teeth working for George Washington, Kennedy, and Reagan…….Crazy!!
"Garfed up"... Another excellent technical term from Rob. 😁👍
I'd of never thought of the air getting compressed in there, but it makes perfect sense! Brilliant, brilliant stuff!
Appreciate it brother!
@@robwendland I remember learning at Deutz engine training that they were able to get almost double the timing belt life by directing some cooling air to be routed into the timing cover.
Same but different 😁
@@MrTheHillfolk very smart stuff!
Very interesting. I wouldn't have thought as much detail goes into this seemingly simple aspect. Thanks so much.
Rob you are a true genius... I love these videos.. Hope to see you and big Terry back very soon... Rock on cam...
HI I have been a drag racing fan for 50 years and a big fan of your channel for the past year ! I really like all the information you present on each video . You ask what we want to see on your channel. I have learned something from each of your videos . I say do and film whatever you want to it is all great!!! THANKS for doing this .
Thanks Daun I sure appreciate the kind words and we will keep it coming!
These videos are great. You're truly in YOUR OWN LANE...🔥😎
Your the man. Thx for the videos. As a street rod guy drooling and wondering how the big dogs do it and u show us.
This guy is so informative and detailed in his videos. So much to know and learn. Very enjoyable to listen to him.
When we ran those brackets on boats we had them engraved and it was a massive help. Belt walk was a big problem and adjusting them in a bilge was a nightmare. Granted we didn't spin them as hard as you guys but we'd spin them for days compared to a fuel car. So getting them to ride right was critical.
Simply amazing the attention every aspect of a top fuel car needs. Was good seeing you again Rob.
You too Mark!
That was a great belt class Rob thanks!!!
Very informative Rob. Thanks for all you do!
BRILLIANT!STAY WELL ROB..I NEVER KNEW HOW MUCH WENT IN TO BLOWER BELTS..
I really enjoy watching your videos. The no-nonsense approach and wealth of knowledge and experience are a joy to watch. Thank you very much!
Sure appreciate the kind words brother!
Damn, I had forgotten how goes into just the idler pulley and belt. Great insight and tutorial Rob. Keep putting out the awesome videos and info. It’s greatly appreciated.
Appreciate it brother!
Thank you for these videos Rob! Great tech and advise for a young(ish) guy starting to run a nostalgia nitro fuel altered in the UK 😎
Hey Rob That domain Star Racer) you're listing has a re-direct in place to a app install prompt. Just making you aware so your customers aren't getting malware extensions installed thinking they're going to your trusted domain. Love the content. Keep safe.
Thanks Rob , great information as always. Very much appreciated !
Look forward to your videos, always something to learn.
One thing to add, speaking from engine timing belt experience.
Always run the belt in the same direction. In operation, belt teeth get pulled in one direction and flipping the belt over will cause the teeth to be pulled in the other direction. This flexing can tear the tooth off the belt. This was a big problem with the old square tooth belts, could be less of an issue with round tooth belts but I'm not taking that chance.
Great advice. One thing I didn’t mention is I always put the belt on so that I can read it if I was sitting on the motor. That way it always gets put on the same direction but what a great point!
@@robwendland said: " if I was sitting on the motor. " Cue pic of of Slim Pickens riding a atomic bomb. . . ..
So much great info. Thanks for all your vids.
Wow a lot more goes into just putting the belt on than i ever thought would. Thanks for sharing. Stay safe an God bless.
Excellent video Rob! Loving every video you post! Btw I'm heading to Steve Gibbs Nitro Revival in November. and I'll be riding shotgun/road tripping with 2 GOATS of NHRA: Herm Petersen and former Top Fuel world champ Rob Bruins. Needless to say I'm gonna soak up every nitro story they have to tell, it's gonna be a helluva trip! Kuhl and Olson car will be fired up by Herm, John Wiebe car and another one not sure yet?
Very informative! BTW it was a pleasure to talk with you for a bit at the Indy race, even if we didn't get to see any cars run Saturday! You are a class act.
Sure appreciate that brother! Good to see you!
Rob had a lot of coffee before shooting this one. Great vid!
Very Cool Info..Thanks
Awesome stuff Rob! Keep them coming 👍
Man, you have the coolest job.
Another great video. I was talking with a friend and he remembers you from back in the day. He used to build chassis and still fiddles around. You might remember him, Rick Esparza. He had only nice things to say and I told him about the youtube channel.
Rick is a great guy I met him through Bill Terrell.
@@robwendland Rick and his son are running a front engine dragster in southwest superchargers these days. Beautiful car he built and he took home a Wally a few weekends back.
I've never given much thought to a nitro-engine belt but I can see Rob has. Interesting stuff. I'm now looking at the blower snout (between the case and the belt) and am wondering what crazy stuff a crew chief needs to know about that.
Another good one Rob. Im headed to the shop now to check on my blower idler setup now.
Don’t hesitate to reach out with any questions!
All right thanks for the video
Thanks for another great video. Cheers 🇦🇺
Appreciate it!
Just subscribed- your last two videos were really well done. Put my vote down as well for a reverser video one of these days- also curious how you balance that motor's power output front to back
Very cool. Neat stuff no one thinks of. Glad i saw u and subscibed
Great video! Thanks
It would be interesting to know whether making the toothed-idler with a convex shape from end-to-end. This is a trick often used to keep a flat belt tracking on a cylindrical pulley.
Great stuff! Thanks for sharing your tricks.
Yeah we’ve ran those and it seems to work on the plastic belts OK but it tries to deformed the tooth by pressing against it.
Another great video!!!
Yes. Awesome stuff!!!
Thanks Rob , can’t get this kind of info anywhere else !
Hmmmmm very interesting 🤔 great vid rob thnx.
Thank You !!!
Very interesting, thanks.
Man. You need to film it in action for us, even better if it has slowmotion to it
That's great thanks Rob
With those belts transferring 800+ h.p. from the crankshaft to the blower pully, its amazing that the stuff even lasts as long as it does.
It is the buffer as well or the damper between the madness!
@@robwendland I can totally understand that. 👌
This will come in handy.
Just a thought, time permitting you could do a fuel school for people trying to get into the sport as a crew member. I hope Terry will make a race soon. Are the bearings ceramic? I've seen some radius tooth belt pulleys modified, kind of looked like a #1 center drill was used to machine a small groove along the root, for other types of racing to get air and debris out from under the belt. Cool video, thanks.
Makes me think about normal auto work and assessing all the belts crazy how that works
Great video sir . Are you going to be at illinois this weekend? September 25th ? Nhra.
Hey Rob. Hope you see this- For some reason (racer brain I guess) this video popped into mind when I saw Bill Millers’s car back on track this weekend. If I remember right, he helped Goodyear when they came out with a blower belt for top fuel cars that had a V pattern in the teeth instead of straight across. Pretty sure Mike Klober jumped on board running it also. It was supposed to be the next big thing, but seemed to disappear almost as fast as it came in. Any particular reason???
More video ideas: Always heard that you can smack a drop of nitro with a hammer and it will explode, and explain reverser operation!
Great video! thanks for posting. When is a dmpe/that style idler system needed vs the old school single bolt style?
I guess it depends on how much overdrive and RPM the engine is running but definitely any alcohol version with a roots style blower and up.
Hello Rob i have a question about cleaning the belts. Do you recommend WASHING the belts with soap and water?
Hey Rob, unrelated question, when Leah Pruitt broke in half a year or two ago does NHRA conduct an investigation on the car to try to ascertain what exactly happened? Where the failure came from ? If so I’m sure it’s a team of people. Is it a collection of crew/car chiefs or is it is it an outside team of guys that no longer or never competed at that level?
Hey Rob, where are you. Are you with a team or have you been busy. Hope this comment finds you well. Some of us older guys have wondered about you. We miss your work and lessons.
Appreciate it brother! Dealing with some cancer stuff but on the repair. Couldn’t talk fir a while….
👍🏻
Who cuts your pulleys Rob? I have to make my own and cut them on a gear hobber since nobody seems to know how to cut large diameter pulleys. As you know the geometry and tooth shape changes slightly when the belt wraps around different diameter pulleys. Synchronous timing belts, difficult boogers to work with ha ha. Great videos as always!!!!!
Rich Schendel makes pulleys and does it the same way as you. We have noticed that we have to cut the profile a little deeper on bigger diameters. Where are you located?
Out in Lubbock Texas. Middle of nowhere bud.
@@robwendland Hi Rob, great, informative video. I was wondering if you, or anyone else ever considered using Pulleys with a Concave, or Convex Pattern to help with Belt Wander? I machined a 1° taper on the upper pulley from both ends on a worn out belt sander. The belts ran true after that. (The belts had been sliding off into the cover, and just never tracked straight.)
Your guy could program in a Tool Path of a Slight Arc negative, or positive while the pulley is held on an Arbor in a Indexing Head, or a Trunnion on the table of the CNC Mill. Might be worth a shot.
Pretty good chance your sanding belt is slipping on the roller since belts like to climb to the high side when they have grip and are able to flex across the width as in a crowned roller's ability to self centered. Cogged belts usually have a fair amount of grip in the travel direction. Does the heavy pull cause them to slide across the width? Interesting stuff.
The devils in the details
I assume it has been tried but would placing idlers to get more wrap on the pullies improve life any?
Yes depending on how small the pulley is and how far away the idle is from the centerline of the motor.
Rob is clearly a Black Belt.
I know this is strictly top fuel stuff… but did the guys as star racer ever say anything like “our belts like more tension”?
Only reason I’m asking is, I just put one on my 565 and set it up like my old rubber/nylon belt was slack wise. Now when I whack the throttle, you can see the “slack” side of the belt rise up off the blower pulley. Basically trying to jump teeth…
Wondering if I need to run it a little tighter, or will it hurt anything. I definitely don’t want to stress the crank or blower snout…
Definitely run it a little tighter. Jumping a tooth is the kiss of death! Doubles the working tinsel strength and will break the belt.
I always thought the belt was changed out for a new one every run (ie you got you some belt manufactor sponsorship).
A lot of the times they are just depending on budgets. But the star racer belt has changed the game.
Some one is super hyped up over belts and idlers
Nailed it!
I don't want to poo poo the design but why is the track straight instead of being curved/convex so you're getting the mechanical advantage and stiffness, have you also considered making the teeth on the pully itself an involute cut? Maybe they are hard to tell but the advantage is that there's only one constant flow contact point throughout the tooth engagement. Finally if you get the sprocket but with EDM you can get the exact profile to match belt and sprocket engagement and not have excess belt strain. Small relief holes could be added so to not trap air and cause vibration.
Who makes plastic belts so I can read up on them?
Thumbed
might better start it!...
Is this guy retiring? Diagnosed with a terminal illness? I'm shocked to see such detailed "tricks of the trade" shared freely.
Did my sticker make it down the track?
Have you not monetized your channel yet sir? I may suggest you please do
?

Hey Rob, Does the 1440 long 8mm come in a 2" wide version or can a 3" be cut down? I want to bring the blower back an inch and narrow the the drive up on my little buggy ua-cam.com/video/e3HU9l3d2nQ/v-deo.html
She doesn't make enough steam to need all that belt anyway
I can have one cut down for sure. Email me
Bill, belts like this are made in a large band and are cut to width. I've worked with many toothed belts in industry and they are frequently cut to order since there are so many variations.
@@robwendland thanks Rob.
@@bobroberts2371 thanks for the input Bob. I was aware they are cut to size just wasn't sure how wide of a market Rob is targeting as 2" wide is not standard for max effort stuff with the exception of a few centrifigal set ups.
How about some English captioning.
