    Lol... High impedance injectors such as these are a bit flaky at duty cycles above 85%.

    I'm thinking the 031J from the Audi TT turbo is a winner as the TT makes 225HP with 4 of them @ 3b fuel pressure and takeoffs are plentiful.

    You should shoot me a price of what you offer so I can weigh my options

    You can calculate how big the injectors should be based on your expected horsepower; and best to not exceed 85% duty cycle for injector health.

    ...plus a touch more for turbo cars...

    EV6 vs EV12 dual cone test. Not super scientific but satisfying to my own curiosity.

    EV12 look good. Seems the vast majority of "in the wild" EV12 are dual cone but both cones spray the valve nicely with very little (if any) wetting of the injector port wall.
    EV6 is a bit dribbly since the injection point is higher and strikes the injector port wall. Single cone version would probably be preferred but I was having trouble finding them with usable flow numbers for anything but stock power levels.

    Have decided on p/n 0280155897 (06A906031S) - 30lb/hr EV12 which are super cheap and plentiful. I'll profile dead times and post the results.
