RE: 4-tec really hitting 70?
well first of all Buckmaster119 you are totally right maybe they don't know how to drive them or break them in and specially they don't know how to TUNE them.
NitroHead5300 yeah they tested the fusion .21 a couple years ago when the 3.3 wasn't out and it's top speed was to be exact 67mph STOCK. The car can go over that but you have to change the gearing for top speed... and now that loses to the 4-tec cause out the box STOCK the 4-tec will do well over 73mph. Like I said earlier you can now change the 4-tec gearing for top speed and with the 3.3 motor you can get well over 85+mph the fusion .21 in the other hand with top speed gears will do the 75mph or lets just say 80mph and anybody that knows about those cars with stock motor and top speed gearing it takes a very long street to get 80mph.
Rushrtr3 my 4-tec with 3.3 with accelaration gears will do 0-65mph in 2.78 sec... Yes your motor has more power but your car has an all metal (aluminum) drive line including differentials, and shafts this creates friction and reduces power to the wheels and even worse when a shaft is a lil bent you lose a TON of HP to the wheels, compared to the 4-tec's drive line is made of belts and plastic keeping friction down to a minimum.
