its not about psi its about hp and the d16 are good for 200-220whp, whether you make 220whp with 3psi or 20psi doesnt matterOkay bc I'd hate to blow the engine after investing lots of money into a decent turbo kit. I don't plan on bashing it or racing it , the most I would run is about 8 psi and I wonder if that's too much to ask for out of a stock Y7
