  • normal t3 boost with 3 turbo-back?

    People with stock t3's and 3" exhausts (no intercooler), what is your normal boost pressure?
    When I had the t25 it baselined out at ~6psi, and the t3 seems to be 8ish according to the super-sweet peak hold on my profec 8)

    Seems reasonable to me, but I've already spent a year dorking around with this, I don't want to blow it up now :?

    86T auto with 120K mile stock exhaust = 5.5PSI

    After CM 3" turbo back = 8PSI

    My 84 did exactly 7PSI on the T3 with no boost controller.

          It works out good post intercooler install because the slight pressure drop brings it back down to stock again like nothing happend :P
