Regardless of what Ford may boast about how much horsepower and torque is being made by their 3.8L V6's, we had to find out exactly how much was made at the rear wheels. After all, in the end what your car puts out is what really matters.
The first to go on was our Option A: Hi-Flo Intake Package, these parts are of the most simple and basic bolt on parts that any vehicle should have.
Next was the Mac 2 1/2 inch dual conversion exhaust kit which gave the car a more stronger tone.
Later the car was lowered using MAC's progressive rate lowering springs. These springs gave it better handling and cornering, not to mention a more aggressive look.
Lakewood shocks were used to maintain a smoother ride and Kenny Brown stiffening components kept body roll and chassis flex to a minimum.
Finally the rear-end with its open 2.73 gears were replaced by Ford Racings Posi-traction unit and 3.73 gears. This gave the mustang a better take off with both wheels at work.
After all the modifications were done, the car was taken to a dyno to see how much power it was making.
The dyno showed 192.5hp and 218.2lbs of torque at the rear wheels. Comparing that to a stock 2003 V6 which produces 149.3hp at the rear wheels. That's 176hp at the flywheel next to Barbara's 228 at the flywheel!!
When determining the horsepower rating on a new engine Ford places the motor on a Dynometer and reads the results directly from the flywheel. When the vehicle is complete the transmission, driveshaft, tire size, weight, are all factors that decrease the amount of power from the engine so the end result is how much the Dyno reads at the rear wheels, or front for a FWD car. So depending on how much modifications are done to a vehicle and what type of parts are used determines the amount of power it can produce.
This is only the beginning for Barbara's V6, in the near future she hopes to put on a Nitrous kit and upgrade the fuel system.
