Just a F.Y.I., detonation normally aspirated is different when using a forced induction application.
Forced induction detonation is much more severe.
With the advancement of electronics,knock detection devices,methanol injection you could run more boost w/cast pistons.
My Syclone has stock weak cast pistons & I have run up to 25 psi of boost.
Others have run as much as 27 PSi on stock cast pistons.
It all depends on how much you want to spend to protect your engine from detonation.
