heres a couple pictures of my new buildup.. arias 11:1 pistons after being coated and the head just after being surfaced before sending it to polydyn for coating.. i'll post pictures of the coated head, manifold and turbine housing after they get back

 

Looks great!!

I am sending my Endyn pistons off to Swain to get Moly and Gold coated....

-How much did you pay for all 4 pistons to get coated?
-What engine is that head for?
-What are the plans for this setup.....

11:1....damn.....I hope you have a good tuner

hm, why do people coat their pistons? For what is that good? What kind of coat is that --- powder? j/k

 

very sexy

 

The moly coating on the side skirts (black) is a self lubricating polymer that will reduce friction and wear.

The gold coating on the top will reflect the heat of combustion away from the piston, instead of having the piston absorb the heat.

If the whole combustion chamber is coated, There will be less heat aborbed by the intake charge, and thus more power. This also allows people to run higher CR's safely.

 

very interessting...and how much is this coating? how much is the benefit from it, I mean how long does this coat hold, doeas it burn away after 10000 miles or so?

 

Polydyn charges $128 for this (dry film on the sides and heat resisant on the top)

this head is for my b16a ported by GTP with full ferrea valve train, cams and roller rockers.. hopefully good for 10000 rpm at 25psi

 

What's a "hoss"?

 

NICE!!!....

do you have a link or a phone # for them?

Swain was going to charge me 200+!!!

Do you know if they can coat bearings as well?

 

I have read about the coating lasting more then 80,000 miles on a modded supra. It was using stock internals that were just coated. I think the article said he was running around 24psi at the track, and like 20 on the street.

Thats all I really know though about that setup.

 

Polydyn's # is 713-694-3296 my company has a pretty good relationship with them so we might be able to get your parts done cheaper then they would do retail.. they coat bearings and basicly anything else you can think of..

you can email me at brianb@gtp-racing.com, btw i can get all ferrea parts (and basicly anything else cylinder head oriented) at great prices!

 

Why does the CC look distorted?

 

here are mine haha, imjust posting cuz im from houston too . http://www.hpcoatings.com costs about 130 to coat the pistons:



the b16 head:
