After the Line to Line coating on the oil pump remember that the high helix parts will become parts that need to be "timed" so that the two pieces per section and the lobes of those pieces are always together. You wouldn't want to have them re-clearance and basically negate the benefits of the coating.
Steve Morris is one of the best UA-camr out there I’m a certified millwright and watching how in detail you are willing to go on any topic inspires me in so many aspects of my life. So thank you Steve
@@stevemorrisracingthose pumps aren’t made in the USA. If you check the US import manifest you can find the manufacturer in China. I was able to track them down, make contact and receive photo confirmation that they did in fact manufacture the multistage pump. The cost of a two unit sample (before covid) was $160 plus shipping and import fees. $160 for two pumps that retailed for $1,600. They also offer multiple anodizing with units in stock in the old red color and clear. The markup is outrageous. Same company makes rear mount fuel / powersteering pumps for multiple racing manufacturers for penny’s of what they retail. It’s crazy.
Back in the day, when I ran a 76mm turbo limited class. I used paint to coat the interior of the compressor housing trying to take up the space. We won a lot, but don't know exactly how much it helped.
TJ!! Good to see you here!! The turbine wheel Steve runs is a work of art, and the “science” would indicate that they are better than stock. (Turbine wheel? Impeller thingy?😂)
These tech videos are among my top favorite videos on the Tube. I love geeky stuff and enjoy the process of making things better. Thank you Steve for not only taking the time to do these videos but also sharing yiur knowledge and explaining things in a way that some of us "dummies" can comprehend and actually learn.
I started using coatings like these on oil pump gears in 2006 in South Africa Cape Town. Company called PowerKote. And they have a massive variety of different coatings. The same time I was there they did a whole bunch of coil coolers and radiators woth a special black coating that helps it reject heat.
In my perfect world. I would definitely have an SMX in my 76 camaro. Unfortunately for me, I'm definitely dreaming. Personally, I think the SMX is a perfect built work of art. In a perfect world, if I had a tea spoon full of your engine building knowledge, 1 could almost build a bullet-proof engine of any kind na, blown, supercharged, or turbo. You are the man in my eyes for a perfect drag and drive engine combo.
Steve is always innovating the race world. The idea of coating those inner rotors to prevent pressure leakage is pretty dang smart. I think you are right about not coating the housing of the pump. Only the rotors should need coating.
Merry Christmas Dewey! Leave the metal shavings, ... have a treat! Dewey's Three Wisemen bearing gifts are, the FedEx, UPS, and Prime delivery drivers.
I simply can't wait to watch every new video you post. I love your in depth tech and it's refreshing to see that even a pro like you gets stumped every now and then. Keep these coming and all the best to you and your team this holiday season.

That long oil pump is just a string of tiny Roots’ blowers. Fun fact… the Roots blower was invented by the Roots brother to be a one-way air blower for mines.
Gene Berg, VW legend and really smart guy, used to blueprint the factory Shadek gear type used to blueprint the oil pump by hard anodized the housing. This would decrease the figure 8 cavity and bottom. The hole for the shaft would be honed to the proper clearance. The steel spur type gears were only verified as to proper size for gear to gear clearance. The stacked height of installed gears and the housing was corrected to flush and the very thin gasket allowed the end clearance needed. Also, our hard anodizing chart at Glenn Tool showed for a .001 hard anodizing call out, that .0005 would be subsurface and .0005 would be the build up above the original surface.
The leakage on both that style blower and oil pump is where the inefficiency comes from. A little bit always leaks back through the rotors. At higher pressures more leaks and the efficiency drops. That leakage pumping the air or oil is also why they create more heat than other styles. It quite literally pumps the same air or oil more than once. Which gets worse as flow is restricted.
Thought provoking for sure ; it will be most interesting to see how the coating works out. Thanks for the great video , and looking forward to the next one.
The question that begs to be asked is, what negative issue is present in the oil pump that needs to be addressed? Reducing clearance on the impeller rotors in relation to one another. and the housing? if that's the case, the CAD design program such as SW has a virtual feature that affords an empirical value between mating parts at MMC. We addressed the issue of measuring a continual helix in rifled barrels through SW when designing the buttons pulled through the barrel blank prior to having the bores hard chrome plated for durability. Merry Christmas to Dewey and his subordinates! Oh and that style of zippered hoodie is absolute fire, Steve. Cheers!
@@strykerentllc Small amount of bypass up the middle but I bet the main advantage is just a sacrificial wear layer that can be refreshed without replacing an extremely expensive part.
@@Ammoniummetavanadate I don't think that coating will hold up to something like trash going through the pump. If it was going to get damaged, I think it will whether there is a coating there or not.
Didn't he say the main benefit was the leakage? The coating creating a tighter tolerance will solve the leakage? I thought he said that was the number one thing after he thought about it and was looking at it. Plus he mentioned its performance at idle
@@--_DJ_-- I agree, he even said that the it's to tighten the tolerance decreasing the leakage allowing better oil pressure when the pump isn't spinning as fast during idle.
Steve back in the day when we were racing we used to throw a couple of shims different thicknesses underneath the impellers of a small block Chevy oil pump and it would increase the oil pressure I'd be worried about putting them on the helix side. I also love when you're thinking I can almost see the gears turning in your head keep up the good work
So you went to PRI. You ended up talking with Line2line. Came up with a plan. Shared plans with Peterson and will report what you find. THAT IS WHAT PRI IS FOR!!! L2L changed my thoughts on coatings. Had so many race engines come in with a piston coating laying in the pan and stacked in the filters. Some with only a few laps. I refused to build my engines with a coated piston. I knew the advantages including tolerances. But I figured that if they couldn't stay on the material then the tolerances would be worse. L2L's actually stays. Only one I trust. And I don't have to tell customers no.
I love the way you guys leave in all the time that the “brain” aka Steve is thinking about what to do and how things are working. I know that a lot of us do the same thing but usually not to the caliber of what he has going on.
I remember hydraulic pumps blew my mind the first time learning about them, for sure. Same with blowers, I always thought it was like dual augers pushing along the middle, lol. Cool what they can do with coatings to the micron these days. Next step would be EDM! I saw a modified 3D printer doing that on a show vid so cheap home units are coming, woo!
Another thing u can check is the compressor wheel tip height vs the gap in the outside edge of the housing. If the wheel tips are taller than the outside gap it is pushing the air into that outside wall at a 90* angle and it can hurt efficiency. You can put the housing in a lathe and try to cut like a 45* or so angle on the entry to the volute to give the airflow a smoother path into the volute. This can help increase compressor efficiency.
20:49 theres several ways to measure the tolerance or clearance between rotors. Plastigauge being one. Modeling clay, wax, or to get real scientific you would use a C.M.M. machine. You would make a CMM model of all included parts and analyze the data to determine clearance.
When you first tested those coatings in the engine, I've been really interested because you talked about turbos. Can't wait to see results on that, but that pump could be a game-changer. Helix is a tricky one, especially that small. Still won't help if you lose a belt!😂 Merry Christmas Morris Family!!❤
must be cold out there Dewey looks like he's staying warm on the shop seat lol more boost for the wagon and oil pressure too .. win win! thanks for the education Steve. From Cali Dancing Manny's Burrito Coverings and Chevy II's
A while back dont remember exactly i read on the forums how the piston skirts was being coated on the Harleys, during a rebuild , clearance was set to what was desired on piston to cylinder. The shops said they had good results with the coating. I certainly use it on my money pits
Merry Christmas to you my Teacher Mr Steve Morris , i truely do deeply appreciate the effort you put into explanations and your Teaching 's . ❤ You input and honesty . God Bless You Val Kyle and all the employees stay safe of Christmas ❤❤
I used an electric gear pump for changing oil on big marine engines. It would rwally move the oil. Some held 11 gallons in each engine. Took no time to empty and fill the engines.
As you were talking through the pump coating, I was thinking it really only needed to be on the rotors, no different than only on the piston skirts, well, not much anyway. I think I'd be interested in a laptop pad if you end up getting some. Merry Christmas Steve, Kyle and Val!
Yo steve...might be obvious but all your videos are to me like giving to my little boy all the secret how it works... At that point it's like,do it what you want, that's what i know. For sure you're like an encyclopedia and damn all your knowlegde you're givin free is unbelievable. Thanks for your hard work!!
Steve, The lobe geometry tries to squeeze the oil forcing it out. As the drive and driven lobes are always touching, pressure loss/leak is not at the lobe/lobe interface, but at the lobe OD with the case and the lobe ends with the case. Tightening up the lobe/lobe clearance will help, but not as much as you think. Tightening up the tolerances on the helix will do the same. PS. Anti-friction coatings work, they reduce oil temperature. Hopefully, the rotors and case are the same material, so they expand together.
Some jet engines use a liner that the blades wear into. It''s a honeycomb material made from hastelloy. I designed a laser welding machine years ago that makes it.
I am from South Africa and would LOVE to come over to your shop and learn from you. But financially, it is impossible for me to even get there. So I am trying to learn through your videos and hopefully one day be able to apply s9me of your teachings in my own build. Thank you for all the effort and time you (and family) put in to explain all the workings and how to fine tune every opponent. 🙏
The largest leak point on a spur gear type pump is end clearance as in side of gear to cover / housing. I've reground end plates , housing depth on milling machine high pressure pumps and brought the pressure back up even though gear tip to housing was pushing 0.050 " .
Hey Steve, wonder if you could run some plasti gauge through the rotors and see if that gives you an idea of what clearance is where. Thanks for the info!
I like your videos, Steve and enjoy watching you, trying to improve things and track down problems. I have noticed that I’ve been getting more frequent headaches after watching your videos. I think it might be caused from you trying to help me learn things and no brains no pains doesn’t apply anymore. 🙃
A few questions that crossed my mind while watching. Does the pump need that clearance between the rotors so there can be an oil, thus preventing contact with each other? And does that oil film also help seal up the clearanced areas? Would the line to line coating be sufficient in replacing the oil film if it is necessary; or would it self clearance back to allowing oil film and only fill larger voids? Thanks for the great content Steve. I learn a lot and really enjoy watching. Your integrity and Christlike nature are impressive. Merry Christmas!
I put the red titanium piston cerakoat on the exhaust side on my 6.0 turbo i put on my 5.9 Cummins an its been on there 2 years and the coating is still there. I live in the rust belt iv been cerakoating everything down to all the nuts and bolts I love the stuff. thanks for sharing
The factory coating on my little l67s m90 rotors had failed and I looked into either sending them away to be re done or buying the gear to do it myself, I had used high fill primer to close the gap on cheap turbo compressor housings with pretty loose tolerances in the past with good results so long story short I experimented with a few primer and paint’s and ended up using a high fill primer! On the lil m90 It lasted 6 months on first inspection and it’s been a couple of years now, it’s got a rear main leak and I’ve got some plans for a couple extra hp so it’s soon to be rebuilt! When it’s apart I’ll find out if the dodgy coat lasted but I sorta have my doubts.
In my experience i had machined a cover for a larger comp wheel. My amature skills led to excessive clearance probabably like 10-15 thou over factory. Did not have the assembly balanced either. Turbo has performed fine daily driven and beaten on for a few years now. Little tdo5h 20g turbo 42lb/hr wheel making about 320-350hp to the ground on a very basic 4 banger setup. Boost usually around 24 psi but have pinned the gate shut many tines for 30 psi falling off to low 20s by redline. Im sure its not optimal but it works well enough. Your car is a work of art keep up the good work.👍
Thanks for sharing the line to line coating purpose lets do a follow up the next time you take the turbos to the track and go on sick week 🤞 you can complete in the wagon. Video after sick week of turbo wheel and housing . Merry Christmas to you and your family Steve morris
Id imagine for the oil pump once it's spinning and has oil going through it the clearances will greatly reduce. I think it'll be more of a longevity thing then a tighter clearance thing. If that makes sense. Or maybe they're one in the same.
Merry Christmas to you and the entire family. You only Line To Line coat the pistons, not the bores. Therefore you should only coat one rotor, not both. You already figured out not to coat the inside of the pump case. Same for hard anodizing, coat one rotor not both. Peterson can send me the royalties for that idea. 😇
Another killer video!!! I wish ppl were more knowledgeable on wet/dry sump setups. They’re amazing and are definitely worth it on any high strung street/ racing motor. Spendy for sure. But when you’re talking about a 10k+ build, spending a quarter (+\- depending on how you go about it) of that to hedge your bets is worth it too me!!
Merry Christmas and God bless brother! We all need to remember one thing- the true meaning of Christmas like Steve said. I think I speak for all of us when I say we're so busy and caught up in everything that we forget the real reason and can't even enjoy Christmas. Slow down, take some time to celebrate Jesus and spend some time with your family. Thats the things that truly matter

Get this to the top 🔝
Excellent point!
First thing I thought as well, paired and timed.
He would probably get it re-coated if he tears is down, but your point is valid.
Had the same thought, and then saw that you had already articulated it well.

Another thing u can check is the compressor wheel tip height vs the gap in the outside edge of the housing. If the wheel tips are taller than the outside gap it is pushing the air into that outside wall at a 90* angle and it can hurt efficiency. You can put the housing in a lathe and try to cut like a 45* or so angle on the entry to the volute to give the airflow a smoother path into the volute. This can help increase compressor efficiency.

In my experience i had machined a cover for a larger comp wheel. My amature skills led to excessive clearance probabably like 10-15 thou over
factory. Did not have the assembly balanced either. Turbo has performed fine daily driven and beaten on for a few years now. Little tdo5h 20g turbo 42lb/hr wheel making about 320-350hp to the ground on a very basic 4 banger setup. Boost usually around 24 psi but have pinned the gate shut many tines for 30 psi falling off to low 20s by redline. Im sure its not optimal but it works well enough. Your car is a work of art keep up the good work.👍
Thanks for sharing the line to line coating purpose lets do a follow up the next time you take the turbos to the track and go on sick week 🤞 you can complete in the wagon. Video after sick week of turbo wheel and housing . Merry Christmas to you and your family Steve morris
Id imagine for the oil pump once it's spinning and has oil going through it the clearances will greatly reduce. I think it'll be more of a longevity thing then a tighter clearance thing. If that makes sense. Or maybe they're one in the same.
Those oil pump gears will be matched on their mesh. They should only be assembled in one orientation after coating.
Merry Christmas to you and the entire family. You only Line To Line coat the pistons, not the bores. Therefore you should only coat one rotor, not both. You already figured out not to coat the inside of the pump case. Same for hard anodizing, coat one rotor not both. Peterson can send me the royalties for that idea. 😇
Merry Christmas! Thanks for the reminder
You are the best. Merry Christmas to all here!!!
Another killer video!!! I wish ppl were more knowledgeable on wet/dry sump setups. They’re amazing and are definitely worth it on any high strung street/ racing motor. Spendy for sure. But when you’re talking about a 10k+ build, spending a quarter (+\- depending on how you go about it) of that to hedge your bets is worth it too me!!
Merry Christmas and God bless brother! We all need to remember one thing- the true meaning of Christmas like Steve said. I think I speak for all of us when I say we're so busy and caught up in everything that we forget the real reason and can't even enjoy Christmas. Slow down, take some time to celebrate Jesus and spend some time with your family. Thats the things that truly matter
Merry Christmas and a happy new year from the Netherlands for your family
Enjoyed your vids over the year 👍- Merry Xmas to you & yours.🎄
Very cool Steve. Looking forward to the results
