Not to get into a debate with you blackSSRS, I've had enough of those over the past few weeks but I've personally seen 147MPH without mods and there was no lack of power, it was still running strong and hard! Professional driver behind the wheel and it was still nervy but a surprising experience to say the least and it was a one time trip when new, just to see what it would do. Mods have since been added and the car has not made another attempt due to lack of safe locations around but it was achieved once and I was pleasantly surprised.

You may have gotten one freak run on the car, but it isn't the norm. Typically the V6 will Max out around the 145 mark, due to Aero drag and lack of down force. Anyone thinking they will run in the 160's stock, have been smoking something.

You're making an assertion of physics, then? Show your work.

No work to show, it's a known fact that the typical passenger car is designed to have lift and not down force and the Camaro is no different other than the ZL1.

[CamaroWinz]

Of course there's work. You're saying that drag and downforce contribute to limit the car's top speed. That's not an arbitrary assertion with respect to any individual car - there's actual math behind it, which determines the specific speeds at which that occurs. So with regard to that assertion, in the case of the Camaro - show your work. If you can't, then your assertion that the car is drag limited to 146 is just you makin' $hit up.

That's all well and good but it doesnt make him wrong, he could in fact still be correct because you havent done the math either. Just leaves it as a hypothesis that needs testing and proved...i've been out of college for 7 years now and I have to work. Find a college engineer to do the math.

He's only wrong in the sense that people have gone faster than he's suggesting is possible.

I don't think a ZL1, designed for down force can do this. LOL

That's pretty much impossible to determine the drag coefficient without precise measurements and a wind tunnel to prove anything. But common sense should tell you the V6 doesn't have the power needed to produce the numbers you are trying to tell. There are videos of drivers trying, and the typical numbers reached are 145 +/- 5 m

Now the ZL1 that is designed to create down force and with 580hp runs out of steam at around 184mph.

I'm saying 145 +/-5 and it runs out of steam ... For a stock V6

Assuming the gearing allows:

Power = Fd dot v = 1/2 * rho * Cd *A * v^3

= 1/2 * 1.2041 kg/m^3* 0.36* 2.35 m^2 * (65.3 m/s)^3 = 190 hp to go 146 mph

Of course, I haven't included frictional forces. This is just the drag.

If you only included that value and assume a 20% loss to the wheels, the camaro can theoretically go 160 mph.

Im not going to check your math but the minute you type out a bunch of metric values and then = hp i feel it needs checked

[camaro-dreamer]

Would the 1 hp / 746 W put your mind at ease, lol?

yes your conversion wasnt listed, -2 points
