Horsepower844182

I was just wondering...what is difference between a '93 LX 5.0 and a GT 5.0? Is it just the body style? Interior different?

And is there a particular reason that in '93 the GT's dropped 15 horsepower?

hdwrench

dunno about the hp drop unless they were just figuring it a different way or something.

LX 5.0 is a GT without all the body moldings basically.

I had a 91 and 92 LX 5.0 notchback (trunk model not hatchback)

I just thought they were cleaner looking... and lighter

They're the same exact thing except for the GT body kit. Not even the VIN numbers can tell them apart.

Ford dropped the HP rating in '93 saying it was closer to the true output which was BS. All they were doing was trying to make the New '94's look better HP wise because they were rated at 215HP and they couldn't have a new design come out with less HP. They also used the Thunderbird intake on the '94 GT's which had a lower profile and aloud Ford to put the strut tower brace them.

Thanks guys

For real......I was wondering why the last year of a model would have lower Hp.

So is y'all guess on the 93...........225?

Could another reason be due to the release of the Cobra...so that there's a noticable difference to consitute the difference in price?

Redbaron93

Back during that time guys who had '93's said there was no difference between their's and earlier models. Ford said it was more of a truer horsepower rating.

But it was really underated? Or was that the actually output?

The GT was under-rated to make the cobra & the next-gen mustangs look better. They did have redesigned... pistons? (Im too tired to look it up) but that didn't make that much of a difference, from what i've heard (never drove a 93). 225 is about right for a 93.

The difference in HP ratings always bothered me too. I found this article in the July 1993 Muscle Mustangs & Fast Fords which didn't answer all my questions but it made some sense:

The Numbers Game: Is That All There Is

If the 235 hp rating of the 5.0 engine motivating Ford's new Mustang Cobra seems low, it is. Surely, the better-breathing GT-40 heads and intake, not to mention the 1.6:1 roller rockers, are worth more than 10 hp over the standard ('87-up) 5.0's 225-horse number--and they are.

So why the lowly 235 figure? Because the "standard" 5.0's horsepower rating has been lowered from 225 to 205 in 1993 due to revised methods of measurement. (The engine and its internal components remain unchanged). That would make the GT-40 Cobra 30 hp better than the bse 93 5.0. If you're of a mind that bigger is always better (and most of the time it is), simply add the 30 hp to the "real" 225 figure and you get 255 hp.

Certainly 255 hp sounds like a more manly number than 235, and it is. But it only begins to indicate the raw potential that lurks inside the 5.0 GT-40 Cobra engine. And it has plenty of that--S.C.


Then, after a little more research I found this more detailed explaination from the 1979 - 93 V8 Mustang Specification Guide by Al Kirschbaum:

For 1979-83, Ford specifications for net brake horsepower and net torque are derived from test results corrected to a dry air temperature of 85-degrees (F) and to an atmosheric pressure of 29.38-in./Hg. For 1984-93, Ford specifications for net brake horsepower and net torque are drived from test results conducted according to Society of Automotive Engineers (SAE) standard J1349 corrected to a dry air temperture of 77-degrees (F), (25-dgrees Celsius) and to an atmosheric pressure of 29.61-in./Hg. For 1993, Ford lowered the 5-liter H.O.'s output ratings without making mechanical changes (aside from hypereutectic pistons) to the '93 engine. The reduced ratings were influenced by a stack-up of minor mechanical changes and are by changes to Ford's engine evaluation processes. Dictated mainly by emissions, fuel economy and customer satisfaction requirements, a series of mechanical revisions had been made since Ford initially assigned the engines 225-horsepower rating for 1987. These include a restrictive resonator added to the inlet tract (1987-93) that produces a five-to-seven-horsepower loss. A small camshaft profile change (1989-93) reduces H.O. output by three horsepower. The restrictive mass airflow meter in the (1989-93) inlet tract yields two-to-three horsepower less than the speed density system. Some monor exhaust system revisions made between 1987 and 1993 also add up to another small reduction in engine output. The second contributing factor in the re-rating of the '93 V8 involves changes in the processes that Ford uses to select engines for testing, and the engine's state of dress (with all engine-driven accessories) during testing. Combined with the 1987-93 mechanical revisions, the revised-for-1993 testing procedures add up to the '93 model year's reduced output ratings. The 1993 Cobra GT-40 engine is rated by the same standards that are used to rate the '93 H.O. version.
