99-04 GT wheel horsepower/torque
 

What kind of horsepower/torque does a bone stock 99-04 GT 5-speed make at the wheels?

Can anybody chime in please?

Thanks!

About 215/225hp at the wheels.

~220-230hp depending on condition

Here's my graph bone stock @ 700 miles

Depends more on the type of dyno. ;)

not enough! its sad. my wifes odyssey has more power.

Wow, really? 215?
I know we have to factor in loss of power due to other components but thats pretty low.

Without getting too off topic, how come a car like the Chevrolet Cobalt SS S/C makes more power at the wheels (stock) than its suggested manufacturer's rating of 205hp? Does Ford measure cars strictly on crank HP while other manufacturers (such as GM) measure it using Wheel Horsepower? Is GM just being conservative and factoring in power loss in their rating while Ford isn't?

I've heard a lot of the Dodge guys complain about the dyno results they were getting on their 5.7 HEMI's. Some were as low as 270 whp. Thats ridiculous for an engine that supposedly makes upwards of 340 HP.

Either way...
227 whp and 273 tq isn't THAT bad. I guess...but 215 is low. Dang.

Regardless, the 99-04 'Stang GT posseses some pretty decent performance (at least to me) on paper. Motor Trend did a test on a 99 GT 5-speed and they were able to come away with a 5.4 sec 0-60 and 14.0 in the 1/4 mile. That is pretty quick by my standards but I'm not too sure how accurate that really is. Seems pretty damn fast and somewhat unrealistic to me for a car that makes as low as 215hp at the wheels.

I'm just doing more research because I will be buying a car next year. No matter how many different cars I look at I always seem to be coming back to the Mustang :)
I was considering a 5.0 but am now strongly considering a modular 4.6 with PI heads (99-04).
The prices are good, they look great and make better power than the 5.0's out of the box. And thats what I'm looking for - a car that will be quick and fun to drive "out of the box". Aside from maybe some intake,headers,exhaust and diablo predator, I will be keeping it stock. Its going to be my daily driver and I won't be going to the track on weekends, no need for supercharging or anything.

our cars are heavy and lack the get up in go. Put a s/c on her though and she bucks like a bronco.

The 14.0 in the 1/4 is about right. Most people that can drive will walk away with that time on a bone stock motor.

Like I said, the HP numbers aren't 100% percent accurate. All numbers depend on the dyno, air temp, humidity, and yes, condition of the car.

Do you guys think the Diablo Predator is a good investment?
Is it relatively easy to use? It seems like a great upgrade to do, and the company makes some decent HP claims - 15-20HP at the wheels. Thats pretty damn good.

By the way Black35th and Purostaff - your exhaust videos make me want a GT Stang even more now! Very nice cars :)

I would recommend SCT. Basically the same price and a lot more tuning shops use the SCT software.

Thanks dude!

awwww you fag!!!

Stupid v6 F-body drivers. :rolleyes::rolleyes:

Very cool.
Seems like there is a lot to pick from.
Something like the SCT X3/SF3 looks interesting since it has pre-programmed flashes. This seems like a good route to take. Are there any drawbacks or limitations for this kind of flash?

Well, get one with a custom tune from Brenspeed.com or Americanmuscle.com. Basically you place the order for the Xcal3 and then tell them all the mods you have and they will write you up to 3 custom tunes.

The only drawback is that your not going to get every last bit of HP out of your car without a custom dyno tune. That's why I said get the SCT Xcal3, you can load one of those "canned" tunes that you get from the place of purchase, but later down the line if you add nitrous or a s/c then you wont have to pay for anything except for the dyno time.

Both are approximately correct for automatic transmissions. The general rule of thumb is that automatics have a 20% parasitic loss. That means only 80% reaches the wheels. Mustang: 260x.80=208 rwhp. Dodge: 340x.80=272.

Manual transmissions are estimated to have around a 12% parasitic loss: 260x.88=228.8.

I believe that all factory published horsepower ratings are at the block but manufacturers have published low number before.

Nice. Good to know.
Thanks!

isnt it sad? my camaro runnin on 7 cyl. still made more power than a stock mustang. they did a lil better with the 3v.


yup yup, i agree with you there.

Ive seen stock gt manuals make 240 at the wheels not 220 becuase what he's saying is that I picked up 30 hp with the simple little bolt ons I added which I know I can squeeze out more on a better day.

If you want a new edge I'd check into getting a 02+. The early years had a intake manifold problem, and coolant would leak. Just a heads up(I already replaced mine).

Really??? Thanks for the info, I'll definitely remember this.

yea but wasnt there a recall on that manifold? im pretty sure there was, and that if it tore up, you could take it to a dealership and get it fixed for free

Yea but it was only for 9 years past the original sell date of the car. Like in my case, I missed it by 2 f*ckin months.....
