Not on an NA no, depends on engine though.

Yb cossy 11:1 cr running 6psi via eaton. Using bike carbs and to get it right overall would need a different profile needle tbh.. Just trying to get the profile I have to behave.

I would go for 12/1, ideal under low boost with that compression, any more boost 11.5/1

For reference I run 11.5:1 on a 3sgte with 18psi with chargecooler.
Engine should be running 8.5:1 cr but I'm not convinced it is,
getting my comp tester checked as it reports 190 psi.
