Probably aimed at DIY engine builders and modifiers.

Just wondering what people are running?
General consensus is 0.0055-0.0065" per inch bore for top, then run larger gap for 2nd ring.

I've also been told to run larger than above, particularly if running high boost.

Thoughts guys?

Gapped my rings by hand using a diamond honing file.

Went for 0.022" on top ring so ~0.0064" per inch of bore.

This is set for high boost.
