- Reducing the wear of your engine components while increasing reliability and performance is a constant battle for casual enthusiasts and motorsport professionals alike, and Gary Huffman of Calico Coatings runs us through some of the options they offer to help us reach this goal.
We’re going to discuss some of the main engine components you might consider coating such as valves and piston wrist pins, along with some you might not like bearings. The ability for clearances and oil weights can be advantageously adjusted thanks to the extra lubrication Diamond Like Carbon (DLC) and Chromium Nitride (CrN) PVD coatings provide is touched on along with how the environment a vehicle is racing in, such as NASCAR or offroad racing can impact what coating is used.
Gary also talks about how coatings can help in situations that shouldn't happen in an engine in regards to metal to metal contact, but sometimes on race day do anyway despite best intentions and practices. With this in mind, a coating can potentially help the engine, car and driver get across the finish line instead of just a DNF in some 'worst case' situations

That guy seems well grounded. Not trying to over sell the product. Nice content.
His comment at the end was a nice nod towards how they operate =) - Taz.
Been using them for years, Bearings, Turbo Manifolds, DLC Pins, Skirt Coatings. The cleaning/finishing is second to none! Great turnaround time, fair pricing and great products.
Love these interviews, be hard to talk to the hp guy staring comp everytime, always wonder who is guna break eye contact first 😂
The engine in my 370Z(VQ37VHR) has a DLC coating on the intake valve train components and the skirts of the pistons. The combination pf this coating plus the properties of the Nissan ester oil, formulated for this particular engine, supposedly reduces the sliding friction between parts to that of the rolling friction of ball or roller bearings.
I have just been involved in the nightmare concerning flat tappet cams and lifters. I had three cams in a row fail immediately with normal lifters. I thought I was at fault as from the beginning I had to reset the valve clearance. I was wrong. The cam and lifters had worn away.
Then I watched a video on You Tube and at the end he mentioned DLC coatings. I phoned Summit Racing and asked if I could exchange my normal lifters for the DLC lifters. They agreed. I paid the about $15 extra for the DLC lifters. They are amazing. Because after I broke in the cam I then had blown head gaskets I got to take a look at the cam and lifters with the DLC. The lifters looked like they came out of the box. The cam looked like it had been polished, not worn down. I will never put in a flat tappet cam without DLC.
Everyone, if you want to avoid all the extra work and expense with normal lifters failing as they are doing massively go to Diamond Like Carbon Coating lifters (DLC).
Always great advice and information on the channel. 💯🏁🏁🏁🔥🔥🔥
Great interview. The products seem like they are worth taking a chance on. The man seems to be very knowledgeable and straight forward.
Thanks for the upload. Keep up the great content HP Academy!
Cheers David, glad you enjoyed it - Taz.
Please do a test using two rotary engines, WPC coating versus their friction reducing equivalent.
Instead of running, measure the torque to turn at a given rpm
*Also WPC with DLC Applied Afterwards!*
"Microinch"
*Americans are going in to Imperial measures not thought possible*
I used Calico on my turbo VW Bug's heads, pistons and valves years ago. 👌🏾
There are manufacturers who gives this coating as a standard on some of their products I know Mahle have their own proprietary coating
Thanks to the team for this feature
this is great for older engines i think
i'm gonna be building 3sge engine
i'm thinking of giving the bore HVOF Tungsten Carbide coating as a test
Those skirt coating don't last too long.. If you're running a race motor and planning to tear down in short intervals, its ok. We've seen Pistons get DLC's completely.. Since pistons are made from Aluminum they arent ferrous and DLC wont stick typically. But there are ways to embed ferrous metals into the piston surface so it can accept DLC
Nicosil it perhaps
This DLC might be a good coating for rotary engine surfaces as well 🤔
Good idea
WPC for the housings and irons
@@dj4monie WPC and Deep Cryogenic Processing. You DCT first then WPC.. and applying Ceramic Coatings and Thermal dispersants to the correct areas does some amazing things
That was very interesting.
This is gold, amazing interview.
Nice content as always. Can you make a video on coatings for performance diesel? Than you
Have u guys done a review in WPC or can u. Cheers
Looks like this is an item that each engine builder will need to evaluate what parts to coat. I imagine there may be greater benefit to coating bearings and journals, perhaps on valves. I'm not certain how beneficial coating a wrist pin might be, I suppose it's the last piece to get lubricated so minimizing wear there might help with minimizing failure in that area.
@@sepg5084 yeah but you need to evaluate which parts are worth coating and which might not be. Maybe you do all your wrist pins and gain 4 HP. Eh, not a bad bonus.
I think coating the cams and contacting valvetrain could be a good option!
Longevity and perhaps some slight HP gain from frictional losses, any applications to the rest of the drive, transmissions (auto and stick) and rear ends?
I Feel Less As Bad. My Engine Has Wiped Out The Mains Bearings 2 Times. First Time The Crankshaft Balance Was Wrong. It Lasted 5000 Miles Before Oil Pressure Hit Zero At Idle. Corrected The Engine Balance And I Got 20,000 Miles Out Of The Engine. Mains Were Wiped Out Again. Main Bearings Clearances Were About .0024". Using 20W50. It's A 2.489" Journal. Our Next Try Is Going To Be .028" Oil Clearance And Switch From P Bearings To H Bearings. We Are Thinking The Crankshaft Is Bending Under Power And It Needs More Main Clearance To Keep The Engine Alive A Little Longer When It Bends. It's The 2 Inner Main Bearings That Have Always Shown The Most Wear.
what you think about SPC treament ? looking very nice
In nitro radio controlled cars, engine manufactures have been using DLC on crankshafts for over a decade.
Coating crankshafts and camshafts as well as rockers would be great in full scale applications.
From what i understand only steel can be dlc coated
Titanium (?)
@@willnzsurf yes He does mention coating titanium valves
There's two main problems with pins . Oiling, and most if not all racing pins flex, or bend, and go out of round, but only while running .
just out of curiosity does this product expand with your components especially when it comes to your pistons expansion
Ive put some on my head ans on my piston tops :)
💯
Would be interesting in which part of the world you can get this coatings and how much you pay for it.
Hey there Nico, Calico is US based and some pricing is discussed. For anything specific you can get in touch with them directly here: www.calicocoatings.com - Taz.
Millenium coatings, up in the PNW. Best quality work, and best prices in the country
Happy this is on my Apple Watch Stainless Steel
I hope these things are better than GMs coatings used in the engines used for Vega cars. That financial disaster(to me and my bank account) left a big old nasty taste in my mouth for GM products. I’ve tried since then, Buick 225, Pontiac Bonneville and Sunbird, Chevy pickup truck, and the taste just wont get out of my mouth. I’ve gone to VW, Ford, Chrysler, Jeep, and I fully like that taste!
Eh? These aren't the same by a long shot. Everybody from Formula 1 to NASCAR uses coating on several parts and Cryogenics & WPC on others. This became mandatory as many series thought one way to keep series cost down was to use force teams to use the same engine over several races. Teams would incur penalties if they have to replace an engine inside the usage window because they don't want to see hand grenades for qualifying which is what teams did in the 80's and early 90's. Only well healed teams could afford to build such things to ensure pole position and then put more reliable race engines in during practice.
Newer common rail injectors also.
Should of talked more about piston coatings.
WPC treatment or DLC treatment?
Both?
I was waiting for you to ask about pistons. A major flub. Or, did I miss it?
Can someone please test WPC TREATMENT ffs
Moto IQ
@@dj4monie ya but does it do anything
@@sniperpronerfmods9811 my jap mate used it on his turbo k20 lotus 550whp. Everything in the engine and the sleeves itself is WPC, after a few years of beating the crap out of it on the street, the drags, he's done about 20 tracks days each with 6 x 20mins sessions and he pulled the engine apart and i kid you not it looked just run in, bearings, rings, sleeves, crank jounal, cams was just unbelievable for the abuse it copped. Im totally sold on these coatings
Wouldn't it be a VERY BAD idea to coat bearings, since the main quality they have is embedability?
Pretty sure Dre picked up on the fact this guy was blowing smoke. Dude is a hack. Look up Millenium coatings, they'll treat you right and not feed you a bunch of bs
Edit: Had to give the first dislike, as much as it pained me to do so. Coatings and treatments are great and all, but this particular company, or at least the salesman they had representing them, didn't really impress me.
2020 supra engine has coated rod bearing from factory. i dont think they would give a coating if it's bad
@@n.shiina8798 It's designed like that from the factory, and only for idle stop/restart when loads are minimal. Not for protection in the event of catastrophic loss of oil pressure. I'm not saying coatings are bad in general, just that doing so on a bearing sacrifices the imbedability. We have good results by just treating and coating the crank. If you have an engine that shuts off at lights and the engineers put coated bearings in it, that's what it needs. But if it doesn't, then it isn't.
@@ldnwholesale8552 What you're leaving out is oil pump failure, pickup tube breakage, hole in the pan, dry sump pump or tank getting knocked out by debris, etc. You two/three are mainly talk about taking advantage of it to gain an advantage in competition. What he was talking about is system failure, no reason to have a oil system break down and lunch an engine. That is why F1 teams monitor everything and tell the driver to bring the car in if they see coolant temps skyrocket because THEY don't want to rebuild engines or have one damaged so badly that they'll incur a grid penalty.
@@n.shiina8798 Lots of OE performance cars and high MPG cars have coatings on the piston skirts. My Focus ST had a coating on the skirts of it's factory pistons.
DICRONITE!!! Can't beat it.
stupid question: can I get a DLC coating on my frying pan?
@Mr Goo User name checks out. :D
Mr Goo you must be trying to get in something tight and old and dry
I was legitimately curious about this. It *may* allow for “nonstick” pans without any Fluoropolymers etc
Also *better than copper heat conduction*?
My dream pan is some polished+coated steel, that or some crazy alloy. If i ever get a (Plasma Assisted) Chemical Vapor Deposition Setup, I’ll 100% try it!
NASCAR tech secret: every piston has a rebel flag etched onto the head.
Not true. Mclaren supplies all the teams with their engine management system.
Why would you choose the flag of a bunch of losers?
@@dj4monie engine management system is not a piston. Try again
NASCAR tems use any technology they can to make their hand built cars last for 600 miles at speed. Otherwise they would melt into the track before the first 100 miles. NASCAR also claims to be using their 'research' to better the automotive industry, but if that worked, their own tires would last more than 40 laps, we'd all be wearing helmets and fire suits, and our 1.3 liter engines would develop about 300 horsepower. So, NASCAR finds ways to make sure their 'stock cars' are nowhere near stock, and those secrets will never be leaked to the auto industry for fear that cars would actually become more fuel efficient, safer and cheaper. The auto industry is satisfied with selling passenger conveniences such as navigation and entertainment systems never found on a NASCAR racer. I mean, who wants to wear a Hans device to go to the grocery store?
They would probably introduce more of this tech into road cars, but no costumer will pay couple grand premium on coatings and other stuff that doesn't really do anything for them or the vehicle.
All motorsports have technology, F1 and Le Mans Sportscar racing are still on the bleeding edge. They turn Cup motors to 9000-9500 rpm, that was unheard of two decades ago. F1 is 13-14,000 rpm with turbochargers and hybrid electric motors. Same with the last generation of hybrids in Le Mans racing. Making 1100-1200 lbs of torque coming out of Le Mans hairpin launches the cars like a rocket to the Porsche Curves.
Genius, the reason why tires in Nascar only last 100 miles is because that's all the fuel the cars hold. The cars average just over 4mpg and have 18.5gallon fuel cells. It wouldn't matter if the tires lasted hundreds of miles if the cars still have to pit to fuel. It takes almost the same time to refuel the car as it does to change the tires with a full tire change taking less time than a full fuel stop. There is also the spectical of a full pit stop where it's an organized effort of the team and a show for the fans. If you think that it's not impressive that the cars last as they do, take any car that has an engine with near equivalent bmep and run it for hours at full throttle and see what happens. There will be few survivors. Some Porsche, ferarri or other high end engines, also hand built, might survive. It's unlikely they will just based on how much oil they will burn.
@@TheSpekkel1This. Engineering is about comprises, and sadly my dream “Internal Combustion Engine to End All Internal Combustion Engines” is probably a dream, and not in an affordable commuter car!
