Piston rings - what are you using and why?

[429244]

I've always used moly. Max boost has been 19psi...

What manufacturer? I have not seen one manufacturer say that their moly rings are good to 19psi.

Nobody in their right mind will "guarantee" a performance part to work. There are far too many variables that can go wrong.

I used Mahle 4032 pistons and moly rings with the 19psi setup. If all you are going to do is go by what advertising a manufacturer uses then why are you even here asking questions from people with experience?

Want to know someone else who uses moly rings that are known to hold high boost levels? Ford. Terminator and GT500 motors use Mahle components and hold tremendous amounts of boost right from the factory. That's with all the tight ring gaps and ptb clearance.

I've always referenced what has been successful for others, not what advertising claims. Ford has given us one of the most successful examples of motors that thrive with forced induction with the mod motors. For this reason I've always based my builds on what has been proven to work with mod motors.

Some builders and manufacturers think that everything needs to be built and clearance like it's a sbc sprint car motor. If that's the route you want to take then this site isn't going to help you much with success stories.
