You know we are all so excited about the new Mustang, but I'm starting to think it may not even be quicker than the old mustang. THey have done EVERYTHING right about the car except one detail they left out, the WEIGHT. The car has gained over a 100lbs over the last GT. Will it even be quicker? The old GT according to MT can do 0-60 in 5.4 and 14.0 in the 1/4 mile. The new Mustang has only gained 40 more HP and only 20 more TQ. Is that mildly increase in power enough to make it quicker?



To say the least I'm a little disapointed in the weight of the new Mustang. I'm excited about how refined and excellent the car is in every other way, but it's beefy!

 

i'm sure if you know the wieght of both cars you can do a power to weight ratio on each one and that will give you the answer.

i think the 40hp 20 tq will easily make up for 100 lbs.

 

Agreed, I think the 40 hp and 20 ft-lbs more than make up for it. Its going to be a mid to high 13 sec car.

 

yep another assurance is how those 800 dollar buggies have 20hp and with you on it can go haul pretty decent. So that is more than enough power to make up for the 100 lbs.

 

 

Heck yes. That's a pretty big jump in HP.

Can anyone REALLY notice a loss in quickness with 100 pounds? That's like having a kid or a small person in the passenger seat. I know I can't.

#1 you don't know its final weight
#2 if its underated, you don't know by how
#3 we haven't seen a dyno to figure out where that power comes in
#4 it has 3.55s
#5 it has a better suspension
etc etc etc etc

If it can't trounce an 04 GT somethings wrong,
considering its been said to have LS1 like performance #s on the street.
(thats what they were aiming for)

 

Exactly.

Expect Mach 1 performance..........I think I've said this 100 times. The Mach was the target, along with the LS1's. You can be sure that the 300hp engine is under-rated.

If early rumours are true, it may be closer to 330 fwhp and maybe 335ft-lbs?
This is pure speculation but there is a good chance we may see those numbers.

If so, it would be a 70hp increase and a 35lb-ft increase. Also consider that with VCT you will get gobs more torque across the range especially at low rpms.

This thing will haul rear.

I'll go out on a limb here but I say expect mid 13's at least. I would be VERY dissapointed at high 13's.

 

Oh, and to answer the original question......... I'm sure it will easily run the current GT.

 

MM&FF says rumors has it that the new 05 mustang will have as much as 290- 295 rwhp.... that makes near 350hp at the flywheel...

 

i dont read car mags but i thought the specs they usually quoted were rear wheel hp... i mean who cares how much it makes at the flywheel if it cant transfer it to the wheels. am i wrong?

 

You are right. If driveline losses are substantial (like some 4x4 vehicles) then what use is high fwhp.

But if you have high rwhp numbers, that is a GREAT thing.

I personally believe manufacturers should list approx. rwhp.

Oh thats good to here

BTW, I thought the weight had already been established...Someone had said it's over a 100lbs heavier...

 

its hard to get slower then the current car

 

Only the MTX's get the 3.55 rear end.
The Autos get 3.31, but the 5 speed auto has a real low 1st gear which will give the 05 auto great off the line performance.

However, the tire diameter is larger on the 05, which makes the combination of the tire diamter and 3.55 rear end work out to the same engine revolutions.

But with that said, the 05 will SMOKE the 99 - 04 Stangs.

The 05 has VVT which will give it a much better low end torque curve.

To really answer the question we would need the torque curves for both the 04 and 05 (how much torque at every RPM) and the real weight of the 05.

But let's take a worst case example and assume that the 05 is not under rated and has only 300 HP. We will also make a worst case assumption that the 05 is 150 lb heavier than the 99-04.

04 Stang 3350 lb / 260 HP = 12.9 lb / HP

05 Stang 3500 lb / 300 HP = 11.7 lb / HP

Any guesses as to which car will be faster?

 

100lbs more? that's nothing... get yourself and 3 buddys off beer and chicken wings and that will more than make up the difference with the 4 of you in the car.

Another weight reduction tip... drive around with 1/4 tank of gas

People forget that the old F-bodys were heavy cars, they were heavier than the Mustangs, that's for sure

 

100 lbs? So you're saying that a fat guy driving the car versus a skinny guy like me .. and I'd suddenly have an IMMENSE edge over the fat guy? Even with 40 hp more? Gimme a break dude.

 

good piont and funny too!

 

I thought the 05 was 200lbs lighter?

 

No that's the engine. It's made of aluminum now. And that's 75lbs lighter. The car's bigger, which is cool. What do you except? LOL. I think they did a good job totally re-designing and keeping it within 100lbs of the current model.
