    I'd certainly carefully check the drivetrain -- guibo and center driveshaft support bearing.

    Sounds like they slapped on the Holset simply to test a launch control feature they're developing. It's not intended for use in any kit.

    Very cool (or, actually hot)!

    I had a Racelogic traction control system some years back on a twin-screw supercharged '99 M Coupe. Set to allow 10% or 15% slip on launch, it sounded like an old...

    Quite right. But with the exception of drifting events, they're rarely seen on road courses.

    Loads of motor but they don't handle particularly well.
