Hey Jack, I just had an idea for your xflow 200

I know its a little late since its already assembled, but have you considered having the combustion chamber and quench area dry film coated with a thermal barrier?

This reflects majority of heat off of the head and back into the combustion process. Unfortunately you should do the pistons at the same time. By coating both heat is kept in the combustion process aiding effeciency and since the charge is hotter you get more pressure pushing the piston down so you get a power increase.

I was thinking that might be the ticket to keeping the heat out of the head and cooling system. You may not have a problem with overheating but if you do this could be a solution.

you seem to be firmly on this coating kick... what you got going on? a sales job? you got any sites with more info? i'll do some google action in a sec, but i wanna know where you are getting your info from, i'm gonna look into it (still need to decide what i want to do though, a 200 build up, or that 351... my mom brought up an idea, i need to think about that one too)

Jack, when/if you read this, just wanted to let you know, that pic in your sig is killing me...

Jealousy is all the fun you think they had.

BTW - Anlushac, i know what the beemers would think, i'm not allowed to post it, but i know what they would think....

I first learned of dry film coatings from "5.0L Tech Guide" published by Mustangs And Fast Fords, 1997.

In it is a write up on the hidden horsepower to found in dry film coatings. Dry films are part of the trickle down of the aerospace Industry brought about by layoffs and closeures. The guys that did those jobs in teh Industry still need to work and saw a market in racing technology.

It is still not widely known. The guys that run arent eager to be blabbing their secrets. Most everyone in NASCAR, Indy , F1, and high dollar racing run it. There are only a handful of companies around the nation that do it and one, Keco, is in Indianapolis.

Im still unemployed, but would love to get a job there.

Back in 1997 it cost about $300 to get all the parts coated on a V8, not including headers. And an engine tuned to take advantage of dry film coatings can pick up on average about 30hp.

Here are some links I have found:

Have fun and enjoy the reading material.

Coatings have definite advantages, but for this engine, I really didn't feel the need to squeeze every last horse out of it.

I have used the spray on anti-scuff coatings on pistons with good results. I've also tried the heat barrier coatings on a small block Chevy, but that was inconclusive. The engine ran well, but it probably would have run well without it. Sometimes, without a dyno and a baseline run, you just can't tell if what you did made a difference.
