So far this is one of the most stupid posts I have seen in the CEN forum.
If you equip the Fusion with a .21 and OPTIONAL gearing it will do 88mph alright.
If you just drop a .21 in a CT4R it will do 85mph without the OPTIONAL gearing.
What if you put a Hot Heads 528 with the OPTIONAL gearing 90-100 on either one.
The key word was OPTIONAL. To define as : involving an option : not compulsory

The point of the article was who was fastest out of the box WITHOUT option parts.
Bottom line stock the CT4 is faster than the Fusion. Now if Shumaker decides to install the OPTIONAL gearing on the truck so you don't have to then I'm sure CEN will counter back with something of their own.
