ah ha, the slightly smaller housing, will come on full chat awesomely quickly and with bags full of torque.
same turbo housing that doug is now running on.
i think 550bhp may be optomistic, but 520bhp should be realistic, not knocking it mate, just ive had the convo's with Martoon myself.
thats going to be an awesome drivers car, and i bet the smile will stay on your face for some time
my rev limit is up towards 8300rpm
