    Good to hear/see a nice screamer :)

    Kind of wish you guys would post the full dyno graphs too. I would like to
    see the torque sometimes.

    Very nice. FB is quite right, this is a lovely example of what a tuner car
    should be.

    Is that a screamer pipe chucking those flames?
    Sounds smooth

    400kw is some serious mumbo.

    What a dream car! This thing must be a blast on twisty B-roads. And it’s a
    stunner too.

    Voiceovers have improved a heap since you started doing them

    Yess! Such a great way you threw this video together, I’d love more of
    these type.

    Peter’s 2009 GT spec street RX8 is a great example of tuner build done
    well. Rather than persist with the factory 13B 2-rotor Renesis engine the
    Promaz team has installed a 20B 3-rotor engine using a turbo race port.
