  2. N54: Hydra Performance Official Product Release Thread

    Quite some time ago we saw the need for another TT N54 option , despite the market being quite crowded already. Existing offerings were, in our opinion, either outright sub-par, overpriced for what...

    You should have unplugged the rear (high-side) PCV connection before pressurizing the intakes. Removing the oil cap (by itself) wouldn't have allowed you to build any boost while testing as it would...

    Pure just posted that an E92 335xi with their turbos did a 10.9 @ 133mph. So that is "faster" while the car above is "quicker". Shame my man didn't get to do further runs due to the crash, because...
  9. N54: new E90 335xi world record - 100-200 5.5s 135+ mph trap speed

    Hey guys,
    I've been kind of out of the loop lately with all things N54-related, however I did manage to e-tune an E90 335xi in Romania a couple of weeks ago, and the results exceeded our...
  10. N54: Don't forget about traction and tranny...

    Don't forget about traction and tranny limitations, both 6MT and 6AT. Manuals don't hold full boost during WOT shifts and have poor traction off the line, while autos can't process high torque/boost...

    I am correct.
    The photo above does not depict the turbine housing "A" in A/R, and is therefore meaningless as the choke point is further downstream of the V-band inlet flange.

    I have personally...

    The Zage/VTT turbos use an investment cast stainless steel turbine housing (a la Tial) that is unique to that application and not available anywhere else. A/R is ~20% larger than stock and this is...

    Don't forget the 22lb cast iron counterweight in the rear crash bar as well!

    N54: I've said this before and I'll say it again,...

    I've said this before and I'll say it again, injector pulse width is meaningless if there is not enough HPFP throughput to take advantage, just like with a conventional PI setup where you are pump,...

    FWIW I don't see coils doing much for boost after spool up since the wastegates/PID would take care of any increased desire to boost for a given map. Keep in mind the stock DME is supposed to run a...

    Would fitting a hydraulic handbrake help with controlling traction by allowing you to apply the rear brakes when it gets squirrelly?
