    Astra Coupe turbo with VXR injectors, what difference?

    I had my VXR injectors fitted at Courtenay today, for those who do not know my car here's it's basic spec:
    VXR turbo
    Full Miltek (pre cat, sports cat and system)
    CS LFMIC
    Water injection (intercooler misting only)
    CS filter and airbox mods

    Here are the graphs, the blue line is with the VXR injectors and the red before (CS3 spec as above), the only changes are the injectors and software (which is their new "low torque" software).

    BHP


    TORQUE


    CAR


    So the top end figures have not changed a huge amount, but the difference at 4k RPM is unbeleivable, the car pulls like a train all the way through the rev range and the extra power feels like the dyno is telling lies, heaven knows what the high toruque map would feel like?

    I am very impressed with the drivability of the car, especially when you consider the 24 deg C ambient temp today and the fact we think if the wteak the actuator a bit we'll see bigger improvements.

    How happy am I, very that how

    Before any one asks, yes you do need the software with the injectors.

    You gotta get a slice of the action, stick to 17" wheels and spend the money else where.

    Dont worry Keith, I have a few plans up my sleeve, apart from some nice new 18's and AP racing 4 pots I am selling my 03 Corsa 1.2 SXI to a mate and the money is all going on the engine, so I will be at Courtenays in the not too distant future with the money burning a hole in my pocket

    High torque is about 330 LBFT, but your clutch may not like it!
