are those housings cerment coated?

Nope, those are my own coatings. Cermet does not work well with movement, tends to break apart.

Customer just wanted a small streetport and a few extra goodies, hopefully he will be very happy with how it turns out. I just have to finish his header over the next few days and we will see...

is it a secret brew coating? or something you'd be able to disclose when i need my housings coated https://www.nopistons.com/forums/pub...IR#>/smile.png

Well its still in the R&D process. If it works I will be offering it. I have several coatings that do work. Extreme oil attraction/rentention coatings for bearings/oil pumps. Heat rejection coatings for rotors/exhaust ports/behind and on exhaust sleeves, headers/turbine housings and downpipes etc.. Those I do know work, last and perform better than anything on the market hands down. The rotor housing and sideplate coatings are being tested...

very interesting.

i like the way you R&D the hell out of these engines.

is that loctite bearing retainer in the first pic?

Did I see a Lamborghini Diablo in the background?

Thats just some grease to help slide the bearing in.

My uncle lets me operate out of his Lamborghini shop....

Breakdown on the synthetic ceramic coatings are:

$15 per bearing- oil retention/attraction/friction reduction

$55 per oil pump-^^

$35 per exhaust sleeve- heat rejection

$300 for a set of rotors to be done- heat rejection on the combustion faces, oil coating for the 2 faces

$300 for both rotor housings to recieve a thermal barrier/oil attraction coating-also includes heat rejection for port/and area behind exhaust sleeve

$500 to have all 4 iron faces - oil retention coating

All the coatings are self clearancing, and the motor parts have to undergo intensive cleaning preperation.

I am still in the R&D process for the coatings on the rotor housings/irons. The rest of the coatings do work, and will outlast the motor. I have even seen motors loose all oil pressure, and if immediatly shut down the bearings still look just like they were freshly coated, versus normal bearings are completly shot. I have also seen motors blown apart, and the thermal barriers coatings have not came off. A valve hit a piston that was coated on a 800hp drag car and the thermal coating did not come off, not to mention it already had 3 race seasons on that motor.

nice work! i wish i had the skills to do my own rebuilds, maybe one day.
