piston coating

[lou schmouder]

I just recieved a set of wiseco piston. Noticed that there coated on the side. Plan to send them to be coated on top. Will the coated on the side help the piston or is there for looks????

It's a dry film lubrication to help prevent wear IIRC.

Why are you coating the tops? I assume it's ceramic coating, I had it done and didn't notice much of a difference at all and opted to go without it for the next set.

If anything, the ceramic coating just helps in the event of going too lean during boosting to help deter melting.

yea I want the extra because of my meth or e85 tune. more then likely meth because Icant get e85 where I am

What would meth or E85 have to do with the coating?

Those 2 fuels burn colder than gasoline you know.

better safe then sorry

No need to spend money where it doesn't need to be spent either.

Which Wiseco pistons are you using?

Thats exactly what it's there for, but seeing as how 4g63 engines like being at around 11.2-11.8:1 afr they don't usually end up with melted crowns or anything like that......you won't really notice alot but because the ceramic crown helps with hot spotting on the pistons to ward off det you could run a little more timing. It really helps on cars with in-efficient cylinder heads though this isn't an issue with the 4g. Crown and combustion chamber coatings allowed me to run nearly 4 degrees more timing on my XR4TI (2.3 liter single cam turbo 4)...made pretty good increase in torque without having to run much boost (stock is 15psi and I made more power without det at stock pressure than I did before on 18psi,but then again thats what running more timing can do for you....but I'm not telling you anything new here you guys know that already......
