Is this true? 2007 Mustang GT Slower?
#21
your point is the same as mine. only those that race for a living care about 4 tenths. but the majority of people dont race, so its not a big deal for most people. and if you're racing with what you got from the factory, you need to rethink your stategy

Also, all times are subject to human error and track and atmospheric conditions at the time. Who the heck makes up these times anyway. MM&FF consistantly tests Mustangs versus CD and MT numbers with improvements that can equal more then 30hp or gear mods- just through sheer competence over a mainstream magazine hack. I think they beat MT with a stock GT500 by over a second in the 1/4, the same improvement you hope for by putting a $6000 supercharger on your GT...
All I know is the shifter is better by far(at least on job 2 07's). I believe the floor pan and some other parts were beefed up for the GT500 on the 07's. The only real weight adding new option would be the power passenger seat. The seat heater elements, additional nav antenna, auto dimming mirrror, aluminum shorty shift ****, and padded dash/armrests couldn't total more then 10-12lbs additional weight on a loaded 07 GT. What do you think the additional nav DVD disc adds 100lbs?

I would be willing to bet that if you added up the added weight from all the options on my car I doubt it would even top 50 extra pounds over a 2005-2006. I also bought mine with the 3.55's.
I think the Wiki's probably used a non broken in car with a different ratio (possibly even a vert).

If true, I'll happy trade four-tenths of a second for tighter build quality and increased refinement.
Those four-tenths - and a lot more - can be made up in the aftermarket readily enough.
If I'm not mistaken, here in Canuckville, GT Premium 5-speeds automatically come with 3:55 gears.

The curb weight for the 07 GT remains the same. The shipping weight on the invoice is with only 1-2 gallons of gas. If you factor in a full tank of gas, the curb weight of 3450 lb for a 07 manual GT is right on the money (isn't heavier than 05-06). A fully optioned out GT/CS, on the other hand, will be heavier.

Are the strut modifications on the 2007 the reason that the 2005-2006 Roush supercharger won't work on a 2007 without this additional purchase?

Or is it something else that is different between the 05-06s and the 07s?

I think with no mods break in will have an effect. My 05 I only had for 2500 miles so I can't say, my 06 I did not get on it enough and now with the 07 I am driving it like a rental and it seems faster than my 06. Even if it slower I am just glad it is Orange with a black interior.

I can't believe you are using theoretical times spewed on wikipedia by unknown drivers as any type of standard....
With repeated perfect runs every single time on a car at the exact same temperature and altitude-a .4 sec swing in its true time is more then 100hp difference in a mustang. Anything other then actual time slips by a reputable driver is stupid. Who even knows what gearset was in the car? Bleg, I'm magazine racing even reading into it...

I'm not 100% sure, but I'll bet a dollar that the parts in the kits are just 05-06 parts that you swap onto your 07 to allow the standard kit to work.
