    QUESTIONS & ANSWERS

    • Q: Tomei MX8265 turbo  1012sti3 months ago

      When they say “good for 450hp”, is that crank or wheel hp? How much psi is max?
      • 0 of 0 people found the following answer helpful

        A:  The horsepower would be measured at the crank. The max PSI is not information that is provided to us, but should be somewhere around 1.3 bar.

        A:  There are many variables depending on your setup, but as a general rule, this would make slightly more power than most 20G setups.

    • Q: what are the difference ?  darkwave837 months ago

      hi, i was wondering what changes they made between the old m8265 and this new model, i have the m8265 now installed its very laggy specially on first gear its kicking full power at 4800 rpm and all other gears at around 4300, i was wondering if this new model have lower spool ? otherwise ill go with the mx7960
      • 0 of 0 people found the following answer helpful

        A:  The biggest changes are an upgraded wastegate actuator and a billet compressor wheel. This will spool better with these changes, although your turbo will typically come on at slightly higher RPMs in lower gears, since the motor is under less load.

    • Q: Boost  22_STI_Tbriggs7 months ago

      on a 2019 STI, what modifications would be needed in order to put this turbo in so that i dont blow the engine?
    • Q: Inlet   JulianSTi7 months ago

      I have a cobb silicone turbo inlet will this fit?
      • 0 of 0 people found the following answer helpful

        A:  Tomei recommends running this with their inlet, as the compressor inlet on the turbo is just slightly larger than an OEM-sized inlet.
