Max boost on a stock motor

['97-2.3L-ranger]

What do you guys think aboyt 14.7 psi on stock pistons and cam rods "factory motor" will be okay?

im pretty sure the answer will be no

maybe 9 if you are saying they are the stock cast pistons an that would be with a good tune. 5 most if you dont have a tune. dont run anything more unless you have forged , then you can crank it up.

10-12 PSI with a safe tune, 15PSI with race gas. At your own risk. :=)
