Hi John, your Scud is fantastic and one of the highest spec'ed I have seen, but its not a Challenge car as I know it. I have only been lucky enough to be in one Challenge car and you would have to strip half your car out just to get close. Has yours had the drivetrain up rated from the scud spec?
By the way I was definitely shaken not stirred after that ride in the Challenge...they are seriously raw....and smile enduring.
