looks like there is an LSD there and sounds like an aftermarket ECU of some description, as the cam swatch sounds very smooth and very different to standard... also a higher rev limit by the sound of it... nice work Mike... now to get a 1/4 mile time ;) ALSO... A little OT, but still on the same lines not really worthy of a new topic... Does anyone know how to get clips off a DVD so I can post them in you-tube? I got the DVD of the day out at Wakefield Park I'd like to post bits up from :D
