The weight should stay about the same, too, since the 5L weighs about the same as the 4.6.

This car will surprise many, have no doubt.

Supercharger from the factory on a GT? Never been done, other than the GT500 no Mustang GT has ever come "from the factory" with a supercharger. Superchargers from the factory on mustangs are historically limited to SVT's (Cobras, GT500) only other options would be tuners such as Rousch at a premium dollar.

I agree. 0 to 60 mph should be 4.6 seconds, maybe 4.5!

If the GT's are prior to 2005 and your starting from a dig then I would believe you are "killing" GT's. But if the GT's are 2007 through 2009 I think you need to explain what you mean by "killing" because you certainly aren't "killing" them nor are you leaving them looking like their standing still. In 2007 the stock GT Vert had 3.55 gears and the coup 3.31 gears. In 2008 the Vert had stock 3.55 gears and the coup had stock 3.55 upon request at time of ordering. The 2009 GT Verts and Coups were running 3.55 gears stock. The 2007 GT Coups going to Shelby to be converted to Shelby GT's came from Ford with 3.31 gears but Shelby swapped them out for 3.55. Upon request and paying the net part cost difference 4.10's would be put in by Shelby. In short with the 3.55 or 4.10 gears you were NOT "killing" GT's running those gears. 3.55 would be head-to-head. With 4.10's the GT Mustang would be starting to pull away from you.

Sorry dude but I have owned and raced GT's, 350Z and 370Z and I will say you aren't "killing" GT's :bs: :bs: :bs:.

But....but.....but.....ZSteve says he's KILLING GT's all the time......:roflpuke2:

I had an 03 that ran 13.9-14.0 stock. 4.10 gears dropped that to 13.5. The 370 would ultimately pull it, but I can say without a doubt that my GT was quicker than my Z from a dig. From a roll would be another story, though, as we are talking 332+ to around 270hp.

As far as superchargers go, you can order your new 2010 GT with a blower. It's a FRPP kit that is usually dealer-installed before you take delivery. It's fully tuned and warranty supported.

As I said the GT's before 2005 I would believe the Z to pull but NOT "Kill". BTW the 03 GT's were making about 260 to the wheels not 270. The 2005 made about 265 to 270 to the wheels. The 2006 averaged about 275 to 279 to the rear wheels. The Shelby GT's were putting down 282 to 286 to the wheels...with an occasional Shelby GT freak putting 290 to 292 to the wheels.

I would say that the best claims that can be truthfully made by a Z owner is that they were trading noses with the later GT's from 2006 to 2009...they certainly were not "killing" them. ANother FACT...the 2010 Mustang GT's are about 2 to 4 HP short of what the Shelby GT's are making to the wheels.

I dont know stangs well enough to know them by years but I do know that Im beating the new style stangs which I guess could be the 05 to 09s??? and I pull on them very quickly and by the time we hit 80 -90 (which is where I usually cut it off for safety reasons LOL) Im more than a car ahead. Now I dont doubt I can do that to the 2010 but I havent gone against one yet that I know of. Im sure the 2010 will be about even with our Z. I can only say about the ones I ve had a go with what ever their year was. Take it for what its worth.

99-04s made 260 at the flywheel. The manuals dynod around 230. I said 270 flywheel because that's about what the CBE was good for on mine.

That is precisely why I said I think you really need to clarify what you mean when you use the word "killing" as the context of your post makes it sound like you were bitch-slapping all of them around with absolute ease...and that is what I take exception to...I know that context just isn't so with the 2006 through 2009 GT models. Anything before that I would say you probably were bitch-slapping them with ease.

Even if the 2011 Mustang is 3800lbs, it will break 13's easy, probably around 12.8. If Ford can really get it at 3500, it should be closing in on 12.5's. In general greater displacement also means torque per HP. Ford's problem may be more getting a good hookup than power.

I agree with you totally in regards to your observation of hookup and power. The Ford modular 4.6 in the 06 to 09 Mustang GT models make 300 ft-lbs of wheel torque in stock configuration. When the torque curve begins its drop the HP is still increasing to reach its peak.

The problem is the torque is all there at launch with Mustangs that the clutch has to be feathered into the launch off the line in order to get the tires to hook right away. And this takes an experienced driver to be able to consistently hook more often than not.....not some weekend wannabee...and certainly not by some puzzy-azz rolling start.

As I said before and I'll say it again...the best anyone owning a stock Z can say is that on any given run a stock Z or a stock Mustang GT (06-10) can win and most of the time they will be trading noses the majority of a race. There is NO KILLING of a Mustang GT (06-10) by a Z.

Figured i'd chime in with my .02, my car club usually does drag race night once a month at the local strip, so far I myself, have raced 3 current generation mustang gt's, havent lost yet with my best win being a full second faster, probably a bad driver, but they were all pretty simple wins. I consider a full second "killing" to be honest, but like I said, he probably wasnt the best driver. If you want to have a numbers battle, the Z outperforms the GT from 0-60 Acceleration, 1/4 mile, Slalom, Skid pad, etc. Here is a vid for confirmation. If i'm not mistaken, that is a 2010 GT.

I’ll be waiting for your .02 when the 2011 5.0 arrive!

Roxy will be packin a GTM or Stillen supercharger by then, im not too worried ;)

Already got 8k saved specifically for it.:happydance:
