Gears N' Stuff

Hmmm,
I think factory install for a 96 is 2.73 for 5 speed, 3.08 for auto, and 3.27 were optional for both. Are you running a 5 speed or auto?

3.73 is a great choice for the GT's power band, and it doesn't cut much off the top end or much off your gas mileage either.

I'm also still learning the details of the gear=torque=HP issues, but I am pretty sure that you do increase torque by increasing your gear ratio...(ie 3.73)

The formula for HP is HP = Torque X RPM/5252

But hear's a more down to earth explaination:

Think about riding a 10 speed bicycle:
If you put your bicycle in a low gear, you can accelerate faster, but your top speed is less (in that gear) because you reach your maximum RPM (leg HP ;-) at a lower speed. Put a bike in a higher gear and you can go faster, but you can't accelerate as fast. However, your body strength (HP) will stay the same in any gear.

When it comes down to it, the 4.6's power band is much higher in the RPMs than a 5.0's.
You want to get to that power band as quickly as possible to maxinize your performance.

The air silencer is located on the side of the air filter housing. It connects the air filter housing (where your filter resides), to the inside of the passenger side fender. If I remember correctly, there is just one bolt and one clamp to remove both the housing and silencer. Take the silencer off, replace the housing, and viola! You're done... You should be able to see part of the filter through the hole on the passenger side of the housing....

The Chilton's manual for your vehicle is #26608. Haynes manual is #36051.

Hope this helps...
