[mustang 1]

These figured were all from the November issue of 5.0 Mustang magazine.
Peak Horsepower
Cobra-274.4 at 5800rpm
Bullitt-236.7 at 5000rpm
Mustang GT-223.1 at 4800rpm
Peak Torque
Cobra-278.8 at 4800rpm
Bullitt-276.2 at 4200rpm
These figures are from a rear wheel dyno.If you use 15% as the correction factor for rated crank horsepower you get the following.
Cobra-315.56 (rated at 320)
Bullitt-272.2 (rated at 265)
Mustang GT-256.5 (rated at 260)
Interesting that the only one to exceed it rated horsepower was the Bullitt.Also on the dyno chart you will notice that the Bullitt bested the Cobra in TQ and HP from 0-4000rpm.
Also note 0-60 difference only 5/100 of a second.A little over 2/10 of a second difference in the 1/4 mile.So as too the people that say only 5 horsepower difference,print this and show them!Actually the Bullitt produced 13.6 more horsepower than the GT and 10.8 ft/lb more torque.I just wanted to share what info I have.Thanx
Mustang GT-265.4 at 4000rpm

 

[BULLITT #1042 (Ray Ackerman)]

Great inf. mustang1,

But i think if the Bullitt made 236.7 at the rear wheels.Using 15 as the correction factor the Bullitt made 278 at the fly wheel,not 272.2. 278 looks even better.... :-B

 

[mustang 1]

Sorry Ray,I just did the math again.236.7 x 15% is 35.505.Add 35.5 to 236.7 is 272.2,at least on my calculator.

Your math is incorrect. You must divide the 236.7 by .85 if you are figuring a 15% drivetrain loss. Remember, the 236.7 is 85% of some higher number. Ray is correct.

 

[donwil]

Right on DilloDave and Ray, your calcs are indeed correct. So we now have ~278 HP at the FlyWheel, this makes it even easier to BITE the BULLITT over the Cobra comparisons. How does Ford get off releasing the 265 HP numbers?

Is this more of a protection statement so that we owners get a "SAFE" repeatable number from Ford?

 

[Dillo Dave]

I believe the reason is twofold. One, if the horsepower got too close to the Cobra, SVT would scream hurt sales and two, remember the 99 Cobra horsepower issue. Owners got very irate when the 99's didn't meet published HP specs. Had Ford said 275HP and then the bullitt only made say 270, wouldn't the Bullitt owners scream bloody murder too??

 

[mystang99]

The issue of 5.0 / Super Ford is the December issue.
if someone has a scanner, they show the complete HP and torque figures from 2600 RPM up to 5700 RPM(Bullitt) and 6600 RPM(Cobra)
it's interesting to see the figures other than peak too
thanks for all the effort you guys!!

 

[MOLJAY]

Regardless of what Ford's CYA talk says, I reply 275 when anyone asks me how much HP it has. That's my story, and I'm sticking to it. :smile:

:bullitt:

 

[GTBULLITT02321]

yeah ha--- My goal either way is to have 350 at the real wells with out nos or a super charger

We all know its basically (hopefully?) impossible to add the freer flowing exhaust, intake and computer, and underdrive pulleys for only 5 hp? It has to be underated---at least thats what I think. :smile: Also, in Mustang Monthly, there was talk of the SVT heads, this isnt true, is it??

The REAL trick is to get 350HP at the REAR WHEELS! hehe

 

[TXBullitt]

Hey 259,

We have Power Improved heads based on Ford Racing aftermarket heads. I posted the stuff that Art Hyde and Mickey D'Armi e-mailed that contained some good info about our cars.

D'Armi also explained the Hp rating although a little on the windy side. The number is "advertisable" not actual.

 

[Bullit1823]

Interesting math fact:

Using a drivetrain loss of 14.25% (div by 0.8575) and the 5.0 article dyno results, you get the following flywheel hps:

cobra 320.00 (rated 320)
GT 260.17 (rated 260)
Bullitt 276.03 (rated 265 :smile

Seemed interesting to me.

Scott

EXACTLY
I've thought that from the begining. After seeing dyno results, 1/4 mile times, and trap speeds posted here it only confimed it.

[From the other side]

I just had to say this, isn't anybody considering that it might just have been testing irregularities inbetween theses two cars? Maybe the next two tested would only have a 5 horsepower difference?

I wondered about the HP so I test drove a GT and Bullitt back to back when car shopping. I tore into each one. The Bullitt has much more noticble power, especially when starting off from low speeds, the great thing is as my car gets more miles on it, I have noticed more power. That's one of the reasons I bought it. The recent numbers don't lie, that's for sure.

 

[donwil]

Hey Bullitt XTC, have you noticed the runs comparing the Cobras and Bullitts? Now a Cobra is minimally another $3000.00 more than a Bullitt. What's up with that? Especially for a car that has troubles putting an extra 55 HP to the ground where it really counts and a questionable IRS.

 

[Pony XTC]

I had a very bad week. My wife just got out of the hospital. I nearly lost her. I don't hate my car, I was just feeling mean and sorry for myself. Please forgive me. I will not post until I feel a little better emotionally. Again, I'm sorry!!
