Dont forget guys, I'm running a 16 at up to 15psi on a non turbo motor, but my car was originally a turbo car, so I have all the turbo parts(ecu, injectors, ect.) I get no knock at 15psi. Just so u know. Been running 11 for 3 years, i hit 15psi(profec A) if I'm racing something realy fast.
Have had no problems, and no rods bending.
