You are correct!
Calculated top speed in 6th gear at 7400 rpm = 167.3 mph.
Figure the rev limiter cuts in just a bit above redline and you'd have 169 mph.
It is clearly drag limited in top gear, unable to pull redline.
There's a guy on youtube who pulled 230 km/hr (142.9 mi/hr). Who knows for certain what the conditions were, though. But, I thought I read in some auto mag that it is around 142 mph.
Now this is for the manual transmission. The auto has an impossibly tall 6th gear, hence the superior fuel economy on the highway, but in 5th it would probably pull close to the manual transmission car.
Our MT cars should pull 128.3 mi/hr in 5th gear at 7400 rpm.
On a side note, I would discourage bouncing your engine off the rev limiter. Yeah, I know people do it all the time, but it's still hard on the machinery with all that vibration at such high stress levels, so ... I wouldn't do it. Jackie Stewart doesn't like it, either. When Sir Jackie talks, I listen.
(I watched Jackie Stewart coming up when he was a youngster. Something to think about. LOL!
)
Here's a pop quiz for you, Shawn. How much is the drag increased by when we double the speed? Speed = 2x, then Drag = ?x
(roughly)
