    I bought a a pair of these from a friend of a friend.
    They have a 4in inlet with a 2.75 outlet. And an .81 a/r
    They are t4 67mm
    Journal bearing. In brand new condition.. What hp can these support? I've searched the forum every way I know how for the past two evenings.. Very little info on these.. I called precision and the guy said they were to old and he could not help.. They are around 8 years old..

    There old enough that they don't have precision on the compressor housings..

    Any help will be appreciated.. Thanks.

    Typical Precision..... Know what the turbine wheel measures? What are they going on? The compressor should support in the neighborhood of 800 fwhp each on the right setup, but roughly 650-700 each at 15 psi would put you in a good place on the map.

    What are your hp goals, at what rpm? Sounds like a decent fit.

    I want to make around 900 to the tires.. Really by 7500 rpm. Think that's possible?

    A lot of the older PTE stuff is Garrett based, thus they really want nothing to do with it anymore. They will do what you want just fine
