Engine coatings continued.......
So a few years back we had a spirited debate about engine coatings. Seems a couple of folks were encouraging others to go out and spend $800-1000 coating engine parts with the promise that if they did they would stand to gain 50+ hp just by doing so....:
A fella entered the thread and proclaimed that he hoped they were right because they had just done it. He privately pm'd me and said he would be in touch with results. I'd love to hear more in this thread how that all worked out.

Had several components coated with different types of coating(s) in a build prior to the discussion mentioned being originated.
Recent freshen revealed that the coating in the combustion chambers and piston tops was flaking off. Seemed more concentrated closer to the exhaust valve. Coating seemed to adhere to valve(s) well. Backside of exhaust were a PITA to clean. Most bearings looked good #1 rod coating was "wiped" clean full circumference of both shells in line with the oil hole. No scoring, the Coating material was sort of balled or rolled up. #2 main upper shell had the same condition starting. Didn't hurt the crank fortunately. Piston skirts showed normal type of indications of wear, slight scratches in bores. Coating in exhaust ports did seem to help get the heat out of the head, barely burns paint off the exterior of the head. Satisfied with that. Questioned the company that applied the coating(s), no help, sacrificial in some cases? Application process? Can't comment on any real power gains, but in comparison to others with similar type builds, any gain would be negligible at best.

Hmmmmm.
So not 50 hp. INTERESTING And the balling or rolling up on the bearings is the same we found. That's why we stopped running coated bearings. Ditto on pistons skirts and tops.

There's a proprietary polishing process for reducing surface friction while keeping super-precise dimensions. It's not a coating.
As for the combustion chamber & slug face...that's the Coating Topic i had assumed was in question for proclaimed HP benefits |

LOL ^^^^^
I have some cool coating on my intake valves and anticipate quite the power increase. |

The only coatings I've saw work are carbon skirt coatings. They wear fit to the bore to deal with bore distortion without scuffing. The work well and keep engine noise down. Other than that?

Yup, that's pretty. Looks like chrome.

Eagle has a similar finishing process they claim increases power. It looks promising but I have not tested the process. Anyone have any non supplier data?

My girlfriend uses some sort of coating on her hair. One of the 12 or so bottles of stuff in the shower. Can't say it helps with HP or wear, but it does smell good

One way to tell if the various coatings and products make a measurable HP difference is when specific sanctioning bodies and rules committees ban or outlaw the coating product or process. If no one pays any attention, in my experience, the HP gains are anecdotal or negligible.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
