Mustang Myths Dispelled

Those aren't really myths though...those are just things that piss guys off about Mustangs.

In my original post i meant myths as reference to mods people do because they read about everyone else doing them and think they will gain HP. These are things like the tornado fuel saver and fart cans.

To sum it all up, a Mustang myth is incorrect tech

Here's my list of myths for the Mustang


#1.) EGR spacer hoses. Everyone thinks bypassing these hoses will gain you HP. They seem to overlook the fact that the 200* coolant is cooling down the 400* EGR gases. Delete the EGR and it's a different story, but i laugh every time i look under the hood of a stone stock Mustang and see the EGR hoses spliced together

2.) When you put on control arms, you can ditch the quad shocks. My answer to that is NOT always. It's hit or miss. It depends on a lot of factors to who is to say if you will need them or not. A lot of people say they are a factory band-aid, but the truth still remains that they work. If you want to remove them for larger tires that's one thing, but if you can keep them in place, it's in your better interest to do so.

3.) Dogbone on rear can be removed after gearswap. Fact is this dogbone comes on every Mustang and is the same exact peice on ever car no matter if your car has 2.73's, 3.08's, 3.27's 3.55's or 3.73's from the factory. They are a dampener for driveshaft vibrations and should remain. There was a really good thread on the t-bird forums i'll see if i can dig up. If you are so concerned about 9 lbs go run around the block a couple times.

4.) TPS sensor. Some guys spend hours trying to set their TPS to some magical 0.97 number or whatever. Just set it somewhere in the 0.9-1.0 volt range and forget about it.

5.) ACT sensor under the seat tricks the EEC into thinking it's seeing cooler air. Honestly..if that made a difference we'd see Z06's with ACT sensors on the roof.

6.) World Class means it's a super strong T-5. Wrong. The World Class T-5 has come in every Mustang since 1985....4-banger or 5.0. All World Class refers to is the synchro style and bearing setup. World class has 3-peice synchros for 1-4 and tapered roller bearings while non-WC uses brass for all 5 gears and straight bearings. The only year a NON-WC T-5 was run in a Mustang was late 83 to 1984 i beleive. The t-5 that everyone thinks is called the World Class is really the 2.95 Z-spec T-5.


I'll edit and add as i think of more.

I know a lot of guys mentioned the silencer as a crappy idea by Ford, but you guys need to realize that EVERY car has an air silencer. There is a reason for it which is to quiet the car down in order to get it certified for noise regulations. If it costs 3HP to do so, well that's the trade-off you need to take. Also, i remember reading that only 1% of vehicle ownersmod their car to the extent you and I do. That means 99% of owners don't care if their car sounds like the world is coming to an end and they gained 2.4HP in the process. The world is full of people who use a car as basic transportation. You and I are a sever minority
