@MR01cobrasvt i agree but just a little bit of performance. The GTs are good compared to other cars but there is so much potential I LOVE MUSTANGS !!!!!!! HELLZ YEAH!
The 99-04 Mustang GT puts out similar power numbers as the LT1 F-bodies. Both models put out around 230-ish to the wheels (give or take) Of course the 5-speed Mustangs and 6-speed Camaros do quite better versus the automatic models..
@fightingscottish86 It is 260hp at the motor (flywheel), but by the time it gets to the rear wheelsm power is lost through the drive-train, and they put down around 230rwhp (rear wheel horsepower) "real world horsepower"...
Automatics lose even more power than the 5-speed cars.
i ran mine on the dyno stock i have a 2000 gt i made 263 hp 291fp @ 5750 rpms u cut the run at 4,000 rpms that car is just breaking in to the powerband in third gear. any how i got board with my 2valve 4.6 and found a cobra motor and trans on craigslist out of a smashed cobra. its nice having the extra gear also put a bigger gear in because of that reason. a blower is the way to go on these cars their only 281 cubic inch ford always make smaller engines for some reason

good numbers man, i just got my 03 gt dynoed today but he weird thing is the dyno told me that my car was putting only 191 to the wheels and 228 foot pounds anyone else think thats a little low even for a mustang. My gt is a 5 speed and has a k&n CAI and magnapacks exhaust
@derschlitza yea it was done on a mustang style dyno and i have heard the rumors that they put out lower numbers but i didnt think it was gonna be that low and i was not happy about the low numbers
@derschlitza this is to gottshallsvt too, the stock mustang gt in this year is 260 rwhp. so even the 230 mark with a cai and magnapacks is a little low.. but i dont really know how dynos go so i could be wrong
@Mustang4life321 260hp is the flywheel ratings... you lose power through the drivetrain, so by the time the power gets to the wheels you're going to lose a few ponies. 230rwhp is where these models come in on most Dynos. Some Dynos are high and some are low. I've seen them go anywhere from 220rwhp tp 240rwhp.
Those numbers are very low. There must be something wrong, either with the car or with the dyno. As for the Dyno: you have to make sure that they measure your car's ratings in SAE units. And as for the car do a basic tune-up and possibly a compression test to know where the problem is. Your numbers would be OK if you had a NPI Mustang (Pre-1999 GT's)
@gottshallsvt Mustang Dyno or Dynojet? Big difference including the weather. You are coming up short by a good amount. The 4R70W even does better at around 210 on a Dynojet.
@nickma71 it was a mustang dyno and i know they have issues so i went to a speedshop close to me and got it dynoed and it put out 231 to the wheels so i was like now thats better
@gottshallsvt hey man u can do all sorts of shit to ur car but if u dont buy a tuner for it then ur not getting your max potential. u can buy a new 2012 mustang and stick a tuner on it before you even leave the dealership and add 30-50HP Ford always gives u room to grow
Ok i still have the paper from my dyno test when i got the car last year. I hit 260 rwhp but 302 lbft? The owner didnt put in any mods, except for a new h-pipe so idk whatsmin my car. Oh its an 02 black premium gt
I have a 2003 gt: acufab 75mm tb and neck, steeda cai, steeda underdrives, slp ceramic coated lt, slp catless short x pipe, steeda axle backs, 4:10 with eaton posi, 31 spline moser axels, vt stage 2 cams with supporting springs and followers, custom tune by dyno speed of Memphis tn, and my numbers are only 297rwh and 310rwt? I'm going back to get a retune and hopefully hit 350 at the wheels unless my numbers are off some how or they did a shitty job tuning it that's alot of upgrades for me to o
@fs03301982 Ive heard that some mustangs make stock numbers on the dyno and some dont even make that. Maybe you started out with less than stock numbers. No big deal. I would also get a tune up.
people yes it did hit 175MPH because its on a FREAKN DYNO!!! OMG there is NO wind to hold it back and the car dont have to pull its entire WEIGHT!!! Its just wheels on a dyno bein turned free by the engine i had my 04 mustang gt dynoed when it was stock and i hit 177mph so yes it can happn on a dyno. People wow people really dont realize that on a dyno its a whole diff world hahaha man...
im in Fayetteville NC and i dont know the elevation here but I took the car to the track last week and ran a 14.2 @98 mph in the 1/4, my car is completely stock including the ford logo mufflers traction control was on and i took off at 2k rpms. just to give ya a heads up
i have a 99 gt with a kenne bell supercharger , even with the tune i dont belive i would see 175. im not a hater but that is a little high. i made 408 rear wheel hp at 115 mph. in a 1/4 mile run i dont think you would reach 100 mph, it would take a while to reach that speed.
@TheBatman498 - Remember this was on a dyno, so no wind resistance. some say the had a limiter.. I guess i was lucky.. this was on the stock ford tune.
@derschlitza The problem with that is a stock gt wont do over 150 period without blowing the engine to hell. ITs not a hp problem you still have plenty of power at top speed (i know from experience). It's that the car is geared for 150 max.
how much power did the dyno tune give you? i have an 01 gt, looking to get a plenum, throttle body, and possibly a tune. car sounds great too...i love my gt.
@gtvapsamtik Yeah. but they are rated at 260 HP. thats crank horsepower. usually everyone uses Crank HP because what sounds better 260 HP or 230 HP. i know what your thinking 230 RWHP. its like stores "buy one get one free....after mail in rebate" no one ever reads the Mail in rebate part. they just see 260
I have a 2000 Mustang Gt auto. I know some of you guys are very knowledgeable when it comes to cars, specially Mustangs. Can someone give me an idea of how much power my car is making to the ground? My mods are: CAI, X-pipe, Flowmaster and 93 octane Diablo Sport tune. What ya'll think?
@jfabian7 well you lose a little more power through the drivetrain with the automatic. so the car started at 260 crank HP, lets say your parts added 25 at the crank, putting you at 285 crank HP. if you lose 15% of your power through the drivetrain you're looking at 242 rwhp. hope that helps if you haven't already dynoed your car.
@V2P22 As far as i know, only the v6 stangs had a speed limiter for the 03 model year. this car did not have a custom tune prior to this dyno. But I have heard of some people hitting a limiter around 132mph i believe. Guess i was just lucky. could have been a different computer program revision..who knows. If you find more info send me a PM i would like to know as well.
Nice Mustang bro. I have a 2000 mustang gt myself and i always wodered how much rwh im making. Mines is auto with CAI, X-PIPE, flowmasters and diablosport tuner. I know there's some very knowledgeable individuals out there. Anybody has an idea. This dude is making 231 hp with just magnaflow mufflers so im guessing im making more than 231 hp.
@jfabian7 A recent run with a 2003 GT auto with magnaflows/K&N/Diablosport tune 70mm throttle body and plenum running on 99 ron (UK) pulled 242rwhp and 281rwtq. Just an idea of what your might pull. The 260 hp that ford rated the car was very modest. There is evidence to suggest its slightly higher.
99-04 limiter doesnt stop at 120 ive hit 145 on mine stock... engine is rated at 260hp lose 20% threw drive train... but dyno jets do read higher then mustang dynos..
Nothing surprising about those numbers and they are actually quite good. A general rule of thumb is that 17% of your rated horsepower is lost in transition from the flywheel to the rear axles. That would mean this GT should have only put out 215hp, but the fact it reached 231 means it's healthy and efficient. Great vid!
yea there is no way, i just got my 2003 gt last sunday, n i hit 110 in 4th gear, n i know that the guy who owned it befor me did somework to it, but idk wat. its deeff not 120 for sure
My '03 GT has weld-on FlowMaster 40 Series mufflers and a stainless BBK CAI, but is otherwise stock. Save for the Mach 1 chin-spoiler. If this car puts out 231 rwhp, i wonder what mine is putting out.
@CBRuRedE maybe 10HP more. True the stock Mustang intake is the closest thing to a built-in CAI, but the plastic chamber that holds the crappy paper filter is very restrictive
i ran my 04 gt 5 speed stock on the strip posting a 13.9, after quite a few mods i shaved a second off posting a 12.9 and thats without drag radials, no nitrous
some charge by the hour others do it per run. figure about $100 to get you some workable numbers. not sure how much it would vary by location. I got mine done for $60.00 But that was for 3 run's.
@ralatorre9 Superior Automotive off of woodland Drive (714)503-1880 has a Dynometer dyno that would be a good place to start. Let me know how you do :)
Hey i need some help....I have a 2000 mustang GT auto. Which i know sucks but i have mande some inprovements to it. I have an Slp loudmouth cat exhaust, upper plenum, throttle body, spacer, BBk cold air intake, mid pulleys and sct performance chip ...i want to dyno it soon...but with all the stuff i got does anyone have a guess to how many horepower i have? alos i was planning to hook up headers and Xpipe....give me some ideas what other bolt on performance parts i should put on?
I have a 2000 mustang gt conv. AUTO...which i know it sucks....bcs its not stick. I have a new slp catback, BBK cold air intake, new throttle body, upper plenum, spacer, mid pulleys and sct chip...the car is 100 times faster then when i first got it...even though its automatic i burn manual cars all the time....from the stuff that i got in it..does anyone have a clue to how many horsepower i have approx? i was planning on putting headers and an xpipe as well...more opinions are welcome.
I have a 04 gt mustang conv auto and I have a cai, t-body & upper plenum, off road xpipe, catback, sct mail order tune and on the online dyno says Iam making 259rwhp btw cino I beat mustang gt sticks all the time.
Listen, I have an 04 mustang gt stick full bolt-ons, complete altered race suspension and full racing exhaust setup. and that's just touching the surface. Stick shifts are fun but many times I wish I had an automatic with my nitrous setup. Launching in 1st gear on a 100 shot of nitrous in my car is pretty scary and not in a good way. Get's some nitrous and enjoy your automatic!
im sorry bro but magnaflows suck balls... i didnt even know ur car was on till u started going, and i still didnt even hear it. sounds stock if not quieter... still a beautiful car tho
the magnaflows i have are just as loud as the flowmasters that were on it before. they dont have a cutting tone which makes it seem quieter. i have a shitty video of them.
does anyone feel like the 99-04 mustang is a let down ? because its torture to turbo due to the k-member issues and boltons get you nowhere, no offense. im planning out mine and i went to a local shop and for a intercooled ati procharger setup fully down they said it'd run me 6-7k which is freaking rediculous. just curious
i guess it depends on what your looking for in terms of horsepower etc. the 99-04 gt's respond fairly well to mods. a set of gears alone well really do wonders for your car. also, that seems a little steep for a supercharger setup to me, If you shop around, I know you can get the job done for under 4k, from what i have seen. dont be afraid to piece your own system together. you can always do a tuner kit, then select your own fuel pump inter/after cooler. that will save you some cash as well
yeah man i appreciate it, when i looked at what all composed of these supercharger kits i was shocked they cost so much considering they came with very few componets. i have a buddy who worked on his cars a ton and has all the tools. so im going to install it with him and go get it tuned. last questino though is what gears do you recommend if im supercharging ? thanks
The rule of thumb seems to be 3:73's for a power adder. I have been in a procharged 01 gt with 3:73's and i can say he was in his power band really fast. anything over that and you would be burning your rears off. I would also advise you into maybe going with some wider tires in the rear to help with traction. Be sure to have your gears done by a pro, thats one area you dont want to go cheap. Throw some video up of your stang when its done, would love to see it!
i love mustang's but they lose mad hp to the wheels most say they produce like 220whp versus the 260 crank which sucks when faggots drive around in srt-4 neon's who put 222whp to the ground versus a 230 crank hp dodge claims
i know, the hp loss is a killer. im getting ready to add a fidanza 2.1 clutch with a billet alum flywheel, that with a new alum driveshaft, im hoping it will free up some of those ponies. plus im also thinking about throwing in some 3.90's, that should put me at my powerband faster.
sweet man let me know what that does, unfortunately mines a automatic but i bought that bc i wanted to turbo and not worry about missing shifts in low gears. plus the one i got was already modded some. let me know how your car runs
89 Iroc with the 5.7 is rated at 240 and 320 lbs of torque. And the body style is the best out there. But the new stangs look way better than new camaros.
There are alot of Stock 6 spd z's running into the high 12's with a set of drag radials and a good driver. I have a friend with a 6spd z stock motor, 4.10's, lid and cutout 12.70 @ 110. He weighs 330 lbs LOL
some of the ws6 trans ams pulled over 300 whp from the factory stock, when they're only rated at 300 at the crank, that's a pretty good amount being underrated so the corvette would look better
@anthony91693 chevy is notorious for underrating their cars so like the ls1 camaros, they said they had 320 hp when they really had 350ish to the crank. then to the whells they would have 315ish. chevy underrates their cars for insurance costs
no the new one is faster compare 260 t0 300 i have seen them running the new one wins for about 3 or 4 cars away.. But if you race a 99-04 with 300 hp you will beat the new ones.
Actually, no you wont. New ones may be a LITTLE hjeavier, but suspension, drivetrain is way more responsive, better aerodynamics. And S197's would definitely win at a road course, due to frame and suspension mods.
did you just say the newer ones are more aerodynamic?...they went from wedge shape to boxier shape for the sake of looks not aerodynamics. But YES the newer ones are faster, but not hugely. the old ones hit 60 in about 5.6 to 5.7 and the new ones in about 5.3seconds. So faster yes, but not murder lol.
i was beating mildly modded 05+ with my 99 mainly due to the 4.10 gear. the new ones are bulkier. why do you think an 04 cobra can pretty much pull the same times as an 06 cobra even with the 100 hp difference...
you obvoiusly dont know wdf your talking about... a stock 98-02 camaro z28/ss auto or m6 runs low 13s easy on street tires. Even the lt1 camaros run high 13s on street tires with a descent driver
Yeah it does depend on driver,I got a mostly stock 01 GT and I can run really close with the SS's until about 120mph then they really pull away from me.
No you don't run really close with LS1's. They dyno well over 300hp to the wheels and run low 13's all day long. Your stock GT is running low to mid 14's.
damn! wind resistance is a bitch. that hit 170+ on a dyno, when my 03 was bone stock itd only do 147 or 148. but then i geared it sod itd only do about 160 at redline.
(3.0L 230 hp 6cyl)vs(4.6L 260 hp 8cyl) mustang has 30 more horse and 102 ft pnds of trq. mustang weighs about 77lbs more. my dollar would be on the stang if the drivers are of the same skill level.
Hi, can someone please tell me the differences between the '03 and '04 GT mustangs? and I also heard that mustangs use an axel that makes both rear wheels nonindependant where if one wheel moves up or down, the other wheel will move the opposite?
Hey Strider, the only Difference between an 03 and 04 gt is going to be some badges that show the 04 is an anniversary edition. as for the Axel, Only the Cobra has an IRS (independant Rear Suspension) and all other mustangs of that year have a Solid Rear Axel.
my 03 GT dyno'd at 268rwhp with a TB, K&N, light weight fly wheel, high flow cats and an aluminum driveshaft...i was running 93 octane..not sure why you'd ever run anything under that in a performance car unless you're dumb.
I'm not trying to be a dick as i really like the 99-04 body style 'stangs, but an LS1 F-body would destroy a stock GT. Unless the guys you raced just got off their learners permits.
I've beaten quite a few LS1's in my stock GT. On paper and with a decent driver the LS1 will win every time, but good drivers are far and few between, and most of the time I end up beating the LS1 guys because they can't hook off the line. I even beat a Grand Sport Vette because of the poor driver inside of it.
its the same as the 2003. 231 hp is rwhp. meaning thats the HP that actually makes it to the pavement. 260hp is at the crank. so you loose a little thru the driveline.
231 HP at the wheels would equal 271.7 HP at the crank if you have 15% loss through the drivetrain. So the factory rating was pretty conservative. Also, some guys get about 245-250 at the wheels stock, which would mean about 285-290 HP at the flywheel...
No, all 99-04 Mustang GTs will have 220-230 hp to the wheels, and about 255-260 to the crank. Many cars aren't equipped with sport clutches, which is where they lose their horsepower to the wheels, which is what gives you your 15 percent. The Mustang has somewhat of a sport clutch so only about 30-40 hp is lost through the driveline.
well it depends on what your putting it up against. It also has alot to do with the driver as well. I can beat Z28's and Formula Firebirds, but ws6's and SS camaros give me a little trouble. as for is it fast, I like to think so :) It has no problems burning the rubber :) since this dyno I have added a Volant CAI, BBK 75mm TB, took out the stock H pipe, and put in a Pypes catted X (see my other video to hear it in action), Also have put in a custom Diablo Tune.
My friend has diablo tuned his mustang gt 1998, and after some time car started rattling. By the way, formulas have 10 hp less than ws6's and they re lighter.
If you have a GT at least run 91 Octane in it.. It boosts the performance a little especially for a Dyno run...

@derschlitza The problem with that is a stock gt wont do over 150 period without blowing the engine to hell. ITs not a hp problem you still have plenty of power at top speed (i know from experience). It's that the car is geared for 150 max.

gtvapsamtik 1 year ago
@gtvapsamtik Yeah. but they are rated at 260 HP. thats crank horsepower. usually everyone uses Crank HP because what sounds better 260 HP or 230 HP. i know what your thinking 230 RWHP. its like stores "buy one get one free....after mail in rebate" no one ever reads the Mail in rebate part. they just see 260

I have a 2000 Mustang Gt auto. I know some of you guys are very knowledgeable when it comes to cars, specially Mustangs. Can someone give me an idea of how much power my car is making to the ground? My mods are: CAI, X-pipe, Flowmaster and 93 octane Diablo Sport tune. What ya'll think?
jfabian7 1 year ago
@jfabian7 well you lose a little more power through the drivetrain with the automatic. so the car started at 260 crank HP, lets say your parts added 25 at the crank, putting you at 285 crank HP. if you lose 15% of your power through the drivetrain you're looking at 242 rwhp. hope that helps if you haven't already dynoed your car.
jihadsquad07 1 year ago
@V2P22 As far as i know, only the v6 stangs had a speed limiter for the 03 model year. this car did not have a custom tune prior to this dyno. But I have heard of some people hitting a limiter around 132mph i believe. Guess i was just lucky. could have been a different computer program revision..who knows. If you find more info send me a PM i would like to know as well.

Nice Mustang bro. I have a 2000 mustang gt myself and i always wodered how much rwh im making. Mines is auto with CAI, X-PIPE, flowmasters and diablosport tuner. I know there's some very knowledgeable individuals out there. Anybody has an idea. This dude is making 231 hp with just magnaflow mufflers so im guessing im making more than 231 hp.
jfabian7 1 year ago
@jfabian7 A recent run with a 2003 GT auto with magnaflows/K&N/Diablosport tune 70mm throttle body and plenum running on 99 ron (UK) pulled 242rwhp and 281rwtq. Just an idea of what your might pull. The 260 hp that ford rated the car was very modest. There is evidence to suggest its slightly higher.

99-04 limiter doesnt stop at 120 ive hit 145 on mine stock... engine is rated at 260hp lose 20% threw drive train... but dyno jets do read higher then mustang dynos..
ogarzajr1 1 year ago
Nothing surprising about those numbers and they are actually quite good. A general rule of thumb is that 17% of your rated horsepower is lost in transition from the flywheel to the rear axles. That would mean this GT should have only put out 215hp, but the fact it reached 231 means it's healthy and efficient. Great vid!

does anyone feel like the 99-04 mustang is a let down ? because its torture to turbo due to the k-member issues and boltons get you nowhere, no offense. im planning out mine and i went to a local shop and for a intercooled ati procharger setup fully down they said it'd run me 6-7k which is freaking rediculous. just curious
joshuaakakidboost 2 years ago
i guess it depends on what your looking for in terms of horsepower etc. the 99-04 gt's respond fairly well to mods. a set of gears alone well really do wonders for your car. also, that seems a little steep for a supercharger setup to me, If you shop around, I know you can get the job done for under 4k, from what i have seen. dont be afraid to piece your own system together. you can always do a tuner kit, then select your own fuel pump inter/after cooler. that will save you some cash as well
derschlitza 2 years ago
yeah man i appreciate it, when i looked at what all composed of these supercharger kits i was shocked they cost so much considering they came with very few componets. i have a buddy who worked on his cars a ton and has all the tools. so im going to install it with him and go get it tuned. last questino though is what gears do you recommend if im supercharging ? thanks
joshuaakakidboost 2 years ago
The rule of thumb seems to be 3:73's for a power adder. I have been in a procharged 01 gt with 3:73's and i can say he was in his power band really fast. anything over that and you would be burning your rears off. I would also advise you into maybe going with some wider tires in the rear to help with traction. Be sure to have your gears done by a pro, thats one area you dont want to go cheap. Throw some video up of your stang when its done, would love to see it!
derschlitza 2 years ago
i love mustang's but they lose mad hp to the wheels most say they produce like 220whp versus the 260 crank which sucks when faggots drive around in srt-4 neon's who put 222whp to the ground versus a 230 crank hp dodge claims
joshuaakakidboost 2 years ago
i know, the hp loss is a killer. im getting ready to add a fidanza 2.1 clutch with a billet alum flywheel, that with a new alum driveshaft, im hoping it will free up some of those ponies. plus im also thinking about throwing in some 3.90's, that should put me at my powerband faster.

Actually, no you wont. New ones may be a LITTLE hjeavier, but suspension, drivetrain is way more responsive, better aerodynamics. And S197's would definitely win at a road course, due to frame and suspension mods.

Hey Strider, the only Difference between an 03 and 04 gt is going to be some badges that show the 04 is an anniversary edition. as for the Axel, Only the Cobra has an IRS (independant Rear Suspension) and all other mustangs of that year have a Solid Rear Axel.

231hp??? The 2002 GT, bone stock is supposed to have 260hp. So the 2003 has less?
brianmef 4 years ago
its the same as the 2003. 231 hp is rwhp. meaning thats the HP that actually makes it to the pavement. 260hp is at the crank. so you loose a little thru the driveline.
derschlitza 4 years ago
oh, ok! sorry for the ignorance.
brianmef 4 years ago
no ignorance about it :) we all have to learn somewhere, and you dont learn by not asking questions.
derschlitza 4 years ago
231 HP at the wheels would equal 271.7 HP at the crank if you have 15% loss through the drivetrain. So the factory rating was pretty conservative. Also, some guys get about 245-250 at the wheels stock, which would mean about 285-290 HP at the flywheel...
LS1FirebirdTA 4 years ago
No, all 99-04 Mustang GTs will have 220-230 hp to the wheels, and about 255-260 to the crank. Many cars aren't equipped with sport clutches, which is where they lose their horsepower to the wheels, which is what gives you your 15 percent. The Mustang has somewhat of a sport clutch so only about 30-40 hp is lost through the driveline.

well it depends on what your putting it up against. It also has alot to do with the driver as well.
