Heat coating on pistons
A lot of people ask me about heat coating pistons. Is it worth it? Are there horsepower gains? Will it save my engine if it lean's out?
Years ago (25 maybe), we started playing with heat coated pistons. Poly moly on the skirt and ceramic on the dome. This was way before we had a dyno or any kind of data acquisition equipment. We had trouble on our nitro engine scoring out the bore. Only a 55% load. It saved us several pistons. then when we started running nitrous on our 2 cycle snowmobiles after one particular bad melt down we went with them in those engines. I think we burned a hole in one of them but that was a driver who was winning a race and wouldn't back off and temps were up over 1700 deg. This past weekend, I was talking to a friend who had built a 30 cube on over 80% load of nitro. We were reviewing his run on his Digitron exhaust temps were good through out the run until it started to pull down into the torque band and the rapidly jumped to nearly 1750 deg, We both started laughing and he told me it was a good thing he put heat coated pistons in. So, I guess its just a tip, piston coatings give you a safe margin. Typically 1500 deg you would start to do damage to the piston or bore. Doing dyno runs I've never seen a gain in horse power but I've never taken the time to tune a engine in without and do a piston only swap and document it either. any actual gains I always figured were from other changes that were done to the engine. |

That's a good bit of information. I'm still green with tuning and playing with these Kohler but that was well worth my time . Thank you for that tip.

Interesting! How do you heat coat a piston? Just curious, I know nothing about this sort of thing.

I did some looking into this last night and it looks like it cost between $25 or $45 per piston depending on what you want done.

you can dump a couple hundred bucks pretty quick, coat the top of the piston, skirt, inside chamber of the head, exhaust pipe, cam , lifters,

Just be glad your not paying the bills to coat a Na$crap Cup engine.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.
MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
