Power Adding Steps

I wrote previously about exhaust opinions for my girlfriend's '04 GT and I thank all of you for your suggestions. Now that she knows what kind of exhaust she wants my girlfriend would like to have more horse power. I have no experience with late model Mustangs since I have a '65 fastback so thats why I am asking for some power adding suggestions. My girlfriend isn't rich so a mod here and there every few months would be fine. So what should we look at doing after installing a cat back exhaust? Also, is the Triax shifter better than the Hurst shifter for the Mustang? I have a Husrt in my Ranger and its a vast improvement over the stock shifter. Any suggestions would be helpful.

All the cheap bolt on mods from the past are now pretty much factory standard. You can spend a couple of thousand dollars for a few upgrades, but will probably not get more than 40-50hp more unless you start spending big bucks i.e. super charger. Rear end gears is your best bet for now. I would go for 3.55 or 3.73 ratio.

...Or 4.10 ;) I have 4.10's in my car and I kinda like it. If I was buying I would have went with 3.73's but only because I had never driven a car with 4.10's. Now that I have 4.10's I think its the best gear out there for out of the whole performance. Oh, and I drive about 750-1500 miles per week, so there are really no driveability issues with the

4.10s. Gas mileage is actually better in the city but worse on the highway, most of my driving is city driving though. I get 18 in the city and about 23-24 on the highway I think from what I have seen(haven't been on a long trip in it yet). As far as shifters, I had a triax in my '93 mustang and I loved it. I'll be making the purchase for one of them soon. Erik D. '94 white lightning '01 white GT

I guess everyone has their own preference, but 1st gear with 4.10's would drive me crazy for normal street driving. I might as well start in 2nd. Gumby '04GT

Yeah thats definitely the truth. I hardly ever use 1st. I can start in second and spin the stock tires easily without giving it any extra revs. I only use 1st when I want to have fun or if I am at the track. Erik D. '94 white lightning '01 white GT

You have a diff. tranny than mine.. so get 4.10:1 rear-end gears. Motive gears are quite nice I hear. A buddy of mine uses them & they have lasted a couple years so far w/ no issues at all.

hasthe best prices that I've seen & I've done a lot of research. If you had mycar.. I'd say 3.73's simply due to the damn high RPM's that 4.10's make yourun even when cruising. Other than that.... do something with the suspension. A set of subframe connectors works wonders & it's there whether you're on the gas or not. Great mod. Steeda Tri-Ax short throw shifter is awesome too.

The tri-ax is a great mod. Makes shifter SO much better. Make sure you get a gasket to put between the tranny and the shifter, it will cut back on noise dramatically.

As all the other posters have pointed out there isn't much you can do to the stock engine to bump up the power without going through some radical re-design. Handling, however, is a different story. Subframe conectors, shock tower braces, castor camber plates, brakes ect. When your done it's like driving a whole new car.
