I wouldn't put any money on that bet.

 

The new Duratec 3.5L Dohc won't come out till the 06 model year. The 3.8 will only be in the new Mustangs for 1 year, and Ford has already said the 3.5L Dohc will replace it in the Mustang. Rumors hint at 250hp (nothing official) for the base 3.5 Mustang, and the 3.5L is said to be capable of as much as 275hp which i'm sure is reserved for higher-end models within Ford motor Co.

SNEAKY NEIL, 275rwhp is not LT-1 #s. But i'm assuming you were reffering to the 255rwhp low-side figures. But i highly doubt that low 255rwhp figure. I personally think the GT will be rated over 300hp. I don't know why you’re set on thinking it'll be lower.

USHotRod, Depending on weight of the GT, and gearing, the new GT might be right smack in Ls-1 territory. There's Ford playing catch-up with the GT once again . The 3400lb-3450lb 305hp Mach-1 which also dyno's at around 275rwhp has already layed down some good low 13 sec 1/4 miles. MM&FF has gotten 13.0 figures and even Motor Trend pulled a 13.2@sub-107mph times with a 5spd Mach-1.

The current GT weighs in the 32XX's. Assuming a 100-150lb weight gain to Mach-1 weight or even a weight-loss, 3.55 gearing, the 3v 4.6 having more low-end grunt, and it coming with a live axle; this low 13 second 1/4's could very well likely be duplicable with a new GT.

 

This thread is everywhere.

Good, LS1 owners are safe from 05' and up stock GTs.

 

oops...
maybe I said too much?

 

My point is, how do you know that the 275 hp should be the one quoted? It seems to me that the lower numbers would be more believeable because you are not going to restrict the car when testing it on a dyno, but, someone could easily do a few things to bump it up. We don't know how many cars dynoed what to see if there are some patterns. Maybe all of the cars but 1 were in the 250-260 range or maybe all but 1 were in the 265-275 range, we don't know. So until the new car comes out and real people get some baseline numbers, I will stay on the conservative side................and I still believe that the new GT will be rated below 300.

 

Fair enough.

A rating of less than 300 will be a real dissapointment though.

 

I'd be real disappointed if it were below 300, also. Although maybe they're really trying to differentiate (sp?) the Cobra when it comes out with like 5098293043 hp or however much it'll have

 

Another thing to note here is that no 2 dyno's will produce the same numbers. They are all independently calibrated and work at different ambient air temps, and even different elevations (as in sea level). You can dyno 281hp on one unit, go right down the street and dyno a 265hp run on a different unit. That is why it is important to do your before/after tesing on the same unit to help assure you of actual gains from your mod.

I myself have not seen any data sheets from an actual dyno run, but my understanding is that the cars (I am referring to anyways) were dyno'ed in stock trim to establish a baseline for engine performance and design parameters for add-on equipment. I really don't think any of these were "ringers" or factory freaks - especially this early in the game. Remember, these cars were released under confidentiality contracts - they were CERTAINLY not released to the press for thrashing and rag-stats.

I have been honest about it... I'm not the guy who dyno'ed the car(s).
Just take it for what it's worth.

 

that's exciting news about the GT. But I thought there was talk of putting the truck based 4.0 (or was it 4.2?) in the base V6 until the Duratec 3.5 was ready. And if the 3.5 will only be ready in 2006 then technically it won't make it into the new Stang for 2 years.

 

If the new GT does have 275 hp then that is the same #'s that the '01 Cobra put put. That is one hell of an improvement.

 

Could be. The details aren't exactly clear yet.

The new Mustang is a 2005 year model. The 3.5 will come out in 2006 year models. That's 1 year after new Mustang is introduced, not 2.

 

Which is odd, because there's nothing that should go "out of calibration" on a Dynojet. You've got a big mass, and some speed sensing - I don't see where the inconsistancy comes from, at least not in the dyno (now, the operator may make a big difference).

 

I found this on the base 2005. According to this article, the base engine will be a 215hp 3.0 duratec for 2005. The 3.5 duratec will replace in 2006. No mention of the ancient 3.8L or the 4.2 truck motor.

I thought this was interesting.

"Look for Mach and GT variants to continue, followed in model year 2006 by an all-new SVT Cobra"

I thought the Mach-1 was limited to a 2 year run (03/04). Has Ford changed their mind and decided to keep the Mach-1 around much longer? If so, that's really good.

I'd like the lineup to look like this:
base= sub-250hp 3.5L 24v duratec
GT= 300-315hp 4.6 24v modular
Mach= 350-390 5.4 32v N/A modular (think 390hp Falcon GT)
Cobra= 460-500hp 5.4 32v S/c'ed modular
