You're negelecting that the 05 stang 3V motor has VVT which will give it a much broader power band.

That's true. I hadn't considered that. Let's hope they're right!

 

A decrease of 100lbs would actually be worth 1 tenth of a second in the 1/4.

 

Like I said, I'm not a drag racing expert! :bang:

 

You also forget the gearing. It has 3.55 now compared to the 3.27 (I think) of the older stangs.

 

I am still surprised that so many folks are hung up on hp, weight, and nothing else when taking into consideration how "fast" or "quick" a vehicle will be. When discussing a potential 500hp Z06 and 500hp Cobra, the Cobra is not destined to lose simply because it weighs more.

There is this thing called torque that largely determines who wins and who loses as well. As a matter of fact, torque is the reason that a n/a 500hp car is slower than a similar 500hp turbo/blown car more often than not. Take a look at Mercedes 600hp twin turbo S Class.

That car packs 700lb ft PLUS of torque. A naturally aspirated motor of anywhere near the same displacement, or even a liter more for that matter, is very unlikely to make 500hp and still get close to that peak torque number. And, there is no way it will make as much torque across the rev range as that turbo 12....especially down low.

Chassis dynamics matter quite a bit too as the 03 Cobra has shown us. With a slight hp advantage and a huge tq advantage it still manages to lose to a current 405hp Z06 stock vs stock, but that has much to do with chassis dynamics. And likely, it has a bit to do with gearing as well. However, my point still stands. A Mustang need not weigh as little or make as much hp as the Z06 to potentially outrun it. Especially if said Mustang is supercharged.
