No. Do not make 14psi on a KA with 370cc injectors. The KA makes more power per pound of pressure than a SR. Not opinion. Not a engine debate. Just stating that you can't use SR boost levels as guesstimates.

Is this due to the displacement of the engine?
Displacement = more air = need more fuel = 370's way too small?
370's even on an sr at 14psi is asking for trouble... so the extra displacement makes it a definet NO NO huh?
