Well, this mustang got a good launch with stock 235 tires, and thats a ****-poor time, especialy for a car that is supposed to run down LS1 Fbodies.

I think that the auto might have better gearing then the M5's. The spacing from 3 to 4 in the M5 might be to much, and there might be a lot lost, to where the A5 has a much nicer spacing.
Why cant Ford spend the money and give it an up to date 6spd manual? If this car means so much to Ford, why not give it the best? Its not like teh T-56 cant handle the massive output by the almighty 4.6 3v...

 

I don't see where it says what tranny this GT had>? The manual gear ratio spread is supposed to be better then the A5. M/T reported the auto fell on its face in 3rd or 4th.

Yeah a T-56, Was'nt like a LS1 could break it either.

 

Ah finally, in a thread on Stangnet the DocGTO guy says the GTs were both M5s...

 

could it be that the gearing , gave the mustang a good start, but a bit amemic in the top end... that, and the brick like aerodynamics of the front of the '05 stang

 

Ahh....who would have thought you'd be able to see a NEW GTO and a NEW Mustang go at it at the dragstrip again??? Very cool.

 

I thought that too.

Although, I fully expected to open this and see claims of 12's. (especially if it was a M*stang guy and with the way their performance claims have been going)

 

I have yet to see a Tremec 5 spd with worse gearing than the ford auto. Why cant you people see that its was most likly a **** poor track with **** poor drivers on a **** poor day. The bigger joke was the modded GTO's pass. In Chicago at Union grove (not a well prepped track) with less than 1 k on it I ran a 13.6 @103 and in Houston with 7k on the car it ran a 13.32 @106. Houston is at sea level and it was a pretty good day for tearin up the 1/4.

That guys GTO should dip into the 12s. That stock 05 GT should run 13.50s to 13.70s all day long. But if you guys still care in 2 months Ill have my GTO with about 10k square off against my Wifes 05 Mustang with about 2.5 k on her. (We are going to pick the car up and then go visit her parents in Chicago so we can break her in) We will run the cars in Houston on the same day with the same drivers.

 

That guys GTO didn't have any really big difference maker mods...How much difference do headers make in an F-body? like .2 or .3 in the 1/4? That GTO was about dead on where it should be.

 

There is more to driving than just the first 60 feet and that E.T. shows it.

 

ET shows that Mustang has NO top end. Whats this thing have, TPI?

His 60' is sub 2 sec. on skinny 235 tires. VERY good.
All his other times are dead on with the GTO, and even ahead...untill about 1/8 when the almost 300+lbs car pulls ahead.
Now, if this Mustang engine is "underrated", then it should be able to stick a lot closer then a half a second.
Where are these LS1 beaters?

 

**** poor drivers and conditions don't get 1.9 60's on street tires. How else was he going to screw his ET miss a shift?

TONY

 

Speaking of gearing....it is hard to draw an exact parallel between the gearing of a manual and that of an automatic. The reason is simple - the auto has a torque converter, which is a fluid coupling (until it locks), and thus has some amount of 'slip' that has to be considered. The manual is always a mechanical coupling (once slippage from the clutch is overcome). Thus, you cannot do a direct comparison.

The A5 does indeed have a nicely-spaced, low-ratio gearset. That is what is going to get it moving smartly, and likely keep it moving well in the first couple of gears (as the evidence tends to show). However, once it hits 4th gear, its a 1:1 ratio just like the 4th gear of the M5 (in fact, 3rd is also about the same in the A5 and M5). At that point, it becomes hindered by the inherent HP-eating tendency of Ford automatic transmissions, and its gearing 'advantage' is taken away. It then becomes a power to weight issue.

I do not know if the A5 locks when it hits 3rd or 4th - that would have to be considered.

About the M5...it is a Tremec 3650, and thus has a very low 1st gear (3.37), which is great for getting a car moving. The problem is that the jump to second gear is quite large, and being a mechanical coupling, there is no way to really compensate for it, vice running 1st gear out to as high an rpm as possible. As discussed above, 4th is a 1:1 ratio, the same as the T56 found in any F-body or Goat or Vette.

Related...based on the evidence in this post, it would appear the new suspension setup works pretty well. It will be interesting to see what happens when sticky tires, gears, etc are put into the mix.

In my opinion, it looks like the new Mustang has a pretty accurate HP rating...within 10-15 HP if its factory numbers. Given that power, its gearing, and its weight, it will make a decent stoplight to stoplight runner, but as we have seen, is likely going to "run out of steam" fairly early.

That said, its still early in the release cycle, so we'll need to see more numbers before we can make an accurate assessment. I think it is safe to say that stock for stock, an LS1 F-body would still outrun it (certainly an M6 would once you get into the higher speeds). The 05 GTO *should* easily take it.

I think it bears saying that I don't believe Ford set out to produce an "LS1 killer" or a "GTO beater" with this car. Perhaps they will with the special versions that are sure to come - but not with this car. It's made to sell to the masses. I bet it will....the local Ford dealer here in Va Beach got one the other day. I dropped by yesterday (Sunday) to take a peak. It was a rainy, gloomy day, and there were 5 people (only 2 came together) standing around the car looking at it. In the rain. The dealership was closed.

Think about it.

 

Funny you say that. Where I am dealerships are closed on Sunday also. My wife and I were looking at SUVs at our local Ford dealership when I spotted the '05 Mustang GT inside. It must have come in just recently as there were two guys inside setting up a display for it. One of the guys saw us staring in the window and told us to come in even though they were closed. Very nice guy! Obviously I took him up on the offer.

I've seen the new Mustang in person before, but this was the first time I had been able to really check it out alone without a big crowd around me. What a wonderful car. Very well built! Quality indeed! I'm 6'3" and 196 lbs. I wear a size 15 shoe. I fit in this car with absolutely no problems. There was plenty of room for my feet too! It felt great also. Seating position was something between a 4th gen Camaro and the 2004 Mustang. Not too low, not too high. Just about perfect. This particular car had the red leather interior with IUP (interior upgrade package). They used real aluminum on the dash (I already knew this, but seeing/touching it in person is quite different). If this car had been black instead of redfire metallic and a manual, I'd probably be trying to make a deal on it right now...and I didn't even drive it.

 

Jesus Christ Bob, if we keep agreeing on posts the world is going to come to an end.

Gearing, gearing, gearing... good point. See my post in the other thread about GT times, says pretty much the same thing, but uses the Bullit as a basis for comparison.

 

Holy mirror image batman! At least before I gained 30+ lbs post-highschool from just laying around Have the same problem I do at bowling alleys, try to get a 15 but they only have up to 13, and you still look like a clown even in those?

Did it feel like it had more front space than the 4th Gen Fbody? Did you have to lean up touch the shifter like the previous gen? I just got to peak at one at the local dealership. No salesman around at midnight on a Saturday night to let me step inside of it
