anti-wear coatings

[dieselgman]

Here is an item I thought might be of interest to the members here... Calico (name brand) anti-wear coatings on CS 18/1 parts: A friend of mine is building up a DES 18/1 with turbocharger and other mods. He is sparing no expense to make everything bullet-proof.



These are CS pistons with CT2 Metallic Ceramic coating on the crowns and CT3 dry-film anti-scuff on the skirts.



Here is a CS connecting-rod bearing with applied CT1 dry-film anti-wear coating.

This stuff is typically specialized for use in the auto racing industry but it didn't cost too much - ($160 covered application costs for 2 pistons and 4 rod bearings), so I think it is within reason for most of us with the single cylinder engines. You just have to plan ahead and send out your parts to North Carolina for the treatment.

wow...great idea !
It would be most interesting to learn what other things he is doing to this engine.
I would love to make a similar project of my GTG 6/1 Listeroid.

keep the pictures coming !

If he paints the engine with flames, it will run smoother and faster too.

Take a look into what the professional race builders do with their main wear parts... specialized exotic materials and coatings.
Calico in North Carolina is a specialist in getting the most performance and life expectancy out of these kinds of parts in the most severe duty imaginable.

I will post his other stuff when I can get his pictures (and permission), but you will be very impressed - as I was. He is turning the rough Indian iron into a work of art!

Would you be interested in stocking bearing shells with CT1 coatings?

Is this the same coating process? http://www.dowcorning.com/content/publishedlit/80-3384.pdf

As far as I know this is the same technology for bearings and piston skirts except that particular spec sheet does not detail the ceramic coating Calico used on the piston crowns.

I think we may prefer to let this trial run its course and check results later on to see exactly how the CT1 fares over time before taking the steps to include it on our bearings... (the product is baked in place so it does subject the shell to high temps). Pistons I think are an even better candidate. We already have the graphite and ptfe coatings available from manufacturing for these parts but have not yet decided to include them in stock. I have thought about including it though, because I have seen far too many scuffed piston skirts and ring failures due to lack of lubrication.

In reality I guess I am of two minds on the overall subject. KISS (Keep It Simple) does apply to these decisions, but technology moves on. I know the old Lister engineers never had these kinds of options on the table or the coatings might have become an integral part already.

Yesterday at the California NASCAR race, I saw 9,000rpm on a tach ; they must be highly stressing the valve train as well. Anyone use PTFE in their Roid oil? I use some in my rail 300MB diesel for many years.

I like it! Please do keep posting if he doesnt mind.

Thanks for the post. I am particularly interested to see if the ceramic coatings on a piston top and face of the cylinder head improve efficiency in any way. It seems to me that by reducing heat loss into the piston and head might produce more power with less fuel.

The BMW guys have had some success with bearing coatings on the 330hp inline six E46 (and other) engines.  Those engines are really hard on bearings. Not sure if it's the same coating, but it looks similar. 

Many modern pistons are coated, however, that's often to help compensate for, and enable amazingly tight piston to cyl clearances. I have to wonder if it will offer any benefit on a listerioid with old world clearances. 

The ceramic coating on the piston crown is still a questionable thing.

i also have thought about a liquid additive for my lister. but read a review from a scientist and he said they do not do a lot. ptfe is Teflon now to get Teflon to adhere to a pan first a special primer is used then the ptfe is sprayed on and placed in to an oven at an extreme heat setting to get the ptfe/teflon to coat the metal. ps his words not mine. must admit if i thought i could spend 50 pound on an additive that worked i would buy it tomorror.
