    there too many variables. it all depends on the set-up example: is it a ball bearing turbo, what type of intercooler, housings size on the turbo, piping size. I can say that you can see up to 400 hp with those type of turbos dialing-in the set-up properly...

    I said 350 based on 20 psi. 330 could be right, too, at 18.

    I know it wasn't a dyno, but I ran a 2Rude back-to-back against a GT32 (similar to a 3071) at 17 psi and the turbo pulled a heckuva lot harder.

    dyno

    hi,

    I think if are you check on dyno SC applications at 18psi right 330hp, this boost with turbo applications close +10% minimum ( or 15% ) so you can see 360 hp sure.

    It would be good to see a dyno pull.

    I'd guess closer to 300hp and all the SC's being much lower.

    this is not easy questions! Not have info about your engine inside.
    Also GT28RS maybe can make a boost 40-60 psi at full. You can us with stock engine maximum 21 psi with Knot controlled ECU . I think 21 psi aprox 360+ Hp.
    But ask Jerry or Malvin from Turbo Tech PR.
