I have t3/t4e .57/.63 garrett turbo. Sorry to ask the what if questions but my friend is curious, and in the interests of selling my turbo I am hoping someone on here can give me a rough idea. On a stock b18b motor + DSM450 (and tuned) with that turbo installed @ 7psi: What rpm would the turbo start boosting? What rpm would the turbo hit full boost? How much horsepower would he put down with that setup on the dyno?
