As we have seen with people putting these cars on dynomometers without the front wheels moving, the engine will begin cutting out (timing retarded) at about 4,300 RPM.

When we put these cars on a dyno that moves the front wheels like I did (Mustang dyno in all wheel drive setup), the rollers in the front drove the front wheels and we were able to do pulls all the way to redline.

So, there MUST be speed sensors on the front wheels.

Others have run 18 inch wheels all the way around as well as people running 20 inch rims all the way around.

As long as you maintain the overall stock wheel/tire height front and rearthen the TC should be fine.
