Hey Dave it has an innercooling system i just drove it 1,000 miles it was about 95 to 100 degrees outside not once did it ever come close to running hot! Also when i had it in overdrive i saved alot of gas it climed hills beautifully in overdrive at speeds of 100 or so! When i had it in regular drive the rpms when up to about 3 and it was louder and seemed to hold back! but i like that drive sound it sounds like a beast coming down the street!

Generally speaking, overdrive (OD) is the highest gear in the transmission. Most automatic transmissions have three speeds and overdrive (fourth speed). Overdrive allows the engine to operate at a lower rpm for a given road speed. This allows the vehicle to realize better fuel efficiency, and often quieter operation on the highway. When you switch it on, you allow the transmission to shift into overdrive mode after the certain speed is reached (usually 70+ km/h ~ 45+ mph) depending on the load). When it is off, the transmission shifting is limited to the lower gears. For normal driving conditions, operation of the overdrive should be enabled only if the average speed is above 70 km/h (approx. 43 MPH).

I disagree with krys- overdrive is not for climbing. It's for highway cruising. It shouldn't kick in until you reach a speed of at least 45 mph. It is used to conserve fuel. If everything is correct with your transmission leave it in overdrive all of the time unless you are towing something or climbing or descending a steep hill at highway speeds. With all the extra stuff you have though I would keep an close eye on the temperature of your motor when on the highway. High performance add ons are not intended to run at a lower rpm and your motor may be happier running a little faster.

If you had the owners manual you would see that "Ford" recomends driving in overdrive ALL of the time with 2 exceptions.
1 when in very hilly situations where the trans will be constantly (searching) shifting back & forth from drive to overdrive.
2 when going down hill when you might need the engine to hold you back.
Other than the 2 listed above keep it in overdrive. :)

You have a performance car - sounds like a nice one.
The roaring sound is because you are in 4th gear not 5th.
You should have it in regular overdrive for normal driving,
drive is for towing and passing on your car.
Also better to leave a stop sign with in town - block to block
Anything above 45MPH, and you should get it in overdrive.
Unless your at the track - then no overdrive ! ! ! ! !

Overdrive off help a non-modified car (horsepower limitations) to handle the demands of high power/lower speed situation. (Hills, city zip zap, etc. ) You have bumped the horsepower up. Your engine is now stronger and can handle additional load. specially on the Highway, keep the overdrive ON.

Overdrive is for climbing. When going up an extremly sharp hill it will bog down then try overdrive.
I accidently blew up my tranny not realizing that it was in overdrive while driving around town.

Use OD when cruising. Better mileage and the engine will last longer
