You mentioned new car, and i was wondering if this GT in question was broken in? Still, how much can it gain after break in process? This goes against the manuals 300lb-ft of rwtq by a whole lot, and i kind of attribute that to Ford's poor automatic transmission record with the mustang and their unpleasant performance sapping tendency. 300wtq for the manual to 267rwtq for the auto is too big a gap.

 

one dyno posted last month had 279 HP...doesn't 253 seem like a pretty wide range in factory output?

 

Well, maybe a strong manual vs a weak auto. We could be looking at the 2 extremes here.

 

True.

I wonder if they were corrected numbers.

 

12 years? How about 19 years. The Buick Grand National was putting down those numbers. Sheesh. Guess in 1993 the Buick GN guys were saying the same thing "Seven years later and the Camaro still can't put up better numbers than my GN."

 

Coudln't have said it better myself. Short, to the point, and oh so true.

It says SAE (actually SEA) in the original post, so I assume they are corrected numbers...

 

The Cobra is a limited, performance version of the Mustang.

Take the 25k-28k Z28 and SS Camaros compared to the 25k-28k Mustang. Not the Cobra, not some special model. Mass produced, the Mustang is still behind the old and outdated Fbodies in performance. Even there skid pad numbere were below the GTO!
When the GTO posted mid to high 13's, everyone knocked it calling it slow and how you could get an Fbody for cheaper and be faster.

 

funny how you guys jump on some oddly low dyno #'s posted by some nobody on the internet, yet, there was a post on stangnet about some dude pulling a 13.2 with a '05 auto and nobody takes that one as the whole truth.I call BS on both of them until I see some verification.Why are some people here just hoping the new stang is a dog???Its American muscle isn't it???I surely do not hope the '07 or '08 Z28 will be a dog,man,I hope its an animal.


By the way............my '05 feels as fast as my mach 1 did.Soon I will have some #'s to back that up.Any stock '98-02 f-bodys wanna meet me at Orlando speedworld anytime soon????

 

That link says 240rwhp and 245rwhp w/ exhaust. He is not counting the runs that had a spike in the graph that gave higher numbers.

 

Don't you guys get tired of saying the same sh*t time and again?

 

Seriously though, we've all in this post so far compared Camaro top engines over the years to this car, L98's, LT1's, LS1's, they were all engines in top models. 4th Gens had no true base V8, it was top model and then there was a top model with add-on's both having the same V8 engine. The GT is to the M*stang what the Camaro RS 305 TBI or later 5.0 TPI RS was to 3rd Gens. Real base V8's work extremely good for sales, have decent power, and give the people who just want a V8 a V8. We haven't seen their top model yet.

Something that Chevrolet needs to look at is how the M*stang does it's special editions these days, they actually make them mean something, in looks and in performance. They need their models to have real differences and options to set them apart from the others.

 

 

The correction factor for Automatic transmissions is 15% not 20%. It's 13% for Manuals.

253.2/0.85 = 297.88rwhp, that's right on for the RATED FWHP.
267/0.85 = 314.11rwtq.

If you read the entire article, however, those weren't the SAE corrected numbers. Corrected they were a baseline of 240rwhp and 245rwhp after the catback install. If you assume a 15% loss for the A5, that's 282fwhp. If you assume a 20% loss, which would mean that tranny sucks bigtime, you get 300fwhp exactly.

As a side note if I use a 20% correction on my baseline run, that equates to 383.6fwhp (361fwhp using 15%).

 

I think a fairer comparison will be when the mach1 and Bullits come out because they will be closer to what the LS1s cost back then. In 2000 your average Z28 sold for 28-29000 and the TA for 30-32000 so even back then our cars were more money then todays Mustang. Now factor in inflation and you get the picture.

For the money the Mustang is a great performer. Now factor in the rest of the packaging improvements and you got real winner. I just hope the Camaro can offer as much car as the Mustang for the price. I have no doubt the F5 will be faster, but at what price? If it starts at over 30, it will be a real disappointment and IMO will turn into another GTO/SSR debacle. It HAS to compete with the Mustang price-wise to be successful.
