i own a '97 mustang GT and if i were to upgrade the gears, clutch, exhaust and CIA. how much hp would i approximately gain?

[StangAddiction]

EHEM...like...10-15...

Gears & clutch = no hp

and your hp depends on exactly how much of your exhuast u upgrade, but dont expect too much from just a CAI and an exhuast.

[Thewolfman456]

If your looking for sheer horsepower power its good to go with turbo or supercharger and then find ways to eleminate the back pressure caused by the exhuast. The pulley's and gears just help you maximize the efficency of the power created by your engine.

you do need backpressure just to tell you

the average catback exhaust gains you roughly 15 horse depending on the system, and the average CAI and tune is good for roughly 15 - 25depending on the manufacturer and the car. I wouldn't get the CAI without a tuner, in fact, and some other guys can correct me if I'm wrong here, but I don't think you can install the CAI without a tuner and expect to see all the benefits from it anyway,but I'm not sure about the 97's on this. Diablosport & SCT are two great tuners, & C & L makes good CAI stuff. Here and Here

thats it? you spend all that money to gain only 10 - 15hp?

i dont even think you gain 15 from and cat back system bcuz i have a borla cat back and im pretty sure i havent gained 15 hp from it....but there is a gain...

you might gain 3-5HP from a catback exhaust

a true CAI might net you another 2-5HP

and yes.. you can most certianly can add a CAI without the need of a tune

a handheld tuner will help you out and probably give you another 5-10 to the wheels.

all in all i'd say you'll see 15HP with the above mods (including the handheld)

[FastBack71]

with a full exhaust you gain at least 20hp

[FLA Dreadhead]

when you say full exhaust you must me headers too im guessing, cuz aint no way in hell you get 20 just from cat back....

Maybe the numbers are lower for the 97's with these upgrades? Every test I've watched, read, or researched has shown at least 10 horse with a good catback, and with all 3 mods done I've always seen at least 30 horse to the wheels, but then I'm researching a different year of car on this. Different numbers for the 97 then?

Yes, backpressure helps with torque. Modulars are known to have low torque compared to windsors.

Nah i dont think so. Not on a stock engine you wont. Maybe if the engine is modded, then you'll seen a 20hp gain from a full exhuast.

----------
And on top of that, i've seen mags with dyno tests proving between 8-10 hp and 5-7tq from a CAI.

No way. Thats just an urban myth. Do a search and you will see. What engines do need is exhaust velocity. If the velocity is too slow (too big of pipes) then the scavenging properties will also decrease as will your volumetric efficiency. So if you have too big of an exhaust system you can loose power, but it has nothing to do with back pressure. Sticking a pressure gauge into the exhaust system is the correct way to determine if you need bigger pipes. Most mustangs will do fine under about 400hp with the stock system. After 400hp you will start to see decent gains from exhaust upgrades.

Gears will make your car feel a lot faster (but no extra hp). As far as the other mods i highly doubt you will feel any change on the butt-0-meter. Most CAIs claim their hp gains because they alter the airflow to the maf in a way that makes the car run leaner. Sometimes they will cause major problems if you do not retune.

no thsoe numbers are for 99-04 i dont know shit about sub98s. i can tell you now you arent going to see 10HP to the wheels from bolting on a catback... maybe if you were twin 67mm turboed =)

[06dkkiser]

with full exaust, which is including headers, modpipe, and catback.. would roughly get you 20 hp and then with a cai and tuner i say you could get 30 pretty easily from it.. long tube headers for the most power.. get ceramic coated.. this is just what i have researched, heard, and seen..

[1SLOW46]

with a 97 i would just do a PI swap before anything else
