### S7 Competition rivals

This should have been compared to the Veyron when it debuted and now the Gunpert. Why these FIA legends aren\'t lapping VIR and the Ring is beyond me.

I wanted to show the kind of difference in CD a wing/more power could make, my estimates used only the basic formula with a very basic estimate for drivetrain loss. Though the much lower CD of the real ACR seems to show that it\'s even easier to spoil the top speed with additional CD than my estimates predict.

If that rear wing is not for visuals, it will greatly increase drag. The goal of any serious racer is downforce, not speed.

Drag = rho*A*CD*V^2

If the S7 TT reaches 230 mph with 750 hp, then it has a .33 CD, for the S7 C to reach 230 mph, it will have a CD of .44. If the S7 C maxes out at 250 mph, its CD must be .343, which is barely more than the S7 TT.

For comparison, the CD for the Viper and Viper ACR [using my estimates] are .39 vs .55

There is no such thing as fast enough. lol. Especially as suspension and aero technology increases.

@E:"I don't see how it could possibly be faster than the Twin Turbo anyway, it has a rear wing."

wow. and you spend all your time chewing my ass...

this car has 250hp more than the tt. and you wonder why its faster?

E 9y ago

I don't see how it could possibly be faster than the Twin Turbo anyway, it has a rear wing.

Also, I could have sworn the car was added already.

Top speed is not even claimed!

Here is the wiki text about this car:

In 2006, Saleen offered an optional competition package for the S7 Twin Turbo. The package offers a 33% increase in power, to a total of an approximate 1000 horsepower (1014 PS/746 kW), as well as changes to the suspension, a revised front and rear diffuser, and an optional aerodynamic package with carbon fiber front and rear spoilers.

Currently Saleen claims a top speed of 240 mph (390 km/h) for the S7 Twin Turbo but with the 1,000 bhp (746 kW; 1,014 PS) upgrade there are whispers that the car has already topped over 260 mph (420 km/h) in testing.
