RCZ, thanks for the comments... does this mean your supercharging ambitions are on hold? Mine are, at least until I figure out which TA and race classes I will run with... don't want to put myself in 'unlimited' categories everywhere and not be competitive (with 650hp vipers, purpose built race cars, etc)
Chris, I'm really interested in what you find out on the brakes... Figure it out and you've got some +reps coming your way !!!
Perhaps you could test combination of ducting and ABS bypass both?? I think the lack of air is a serious issue as well
