Piston Ring gap

[German Boy]

I once again with a question.

Which end gap get the Manley Piston Rings for 90.2 bore.
Manley Piston with Thermal Barrier Coat and 8.5:1 compression.
The boost pressure will be 22-23 psi.
I mean 0,025 inch (0,635mm) range for all three rich, but am unsure.

Ralf
Thanks for the help.

At that boost pressure I would not recommend moly rings. Do you know what kind of rings you have?

The rings should have instructions with a formula that will get you real close, then it is preference beyond that usually. Also you can contact the manufacturer and they can help with your decision. FFS
