Well, I was joking (see laughing icons), but now that you mention it, a stock SE won't push 7K in 5th gear. Not enough HP, not even a stock SVT can go that fast.

So, either you were in 4th, your tach is off, or your clutch was slipping.

My guess is a stock SE prolly can grab about +/- 125MPH before it runs out of steam. You need the xtra 30 ponies in an SVT (plus some of the aero stuff) to reach 143 (and that still isn't 7K RPM).

Twice the speed is 4 times the horsepower. It takes about 4x the HP to do 100 as to do 50. it takes 9 times the HP to do 150 as to do 50. (This is only accounting for wind resistance, their is some rolling resistance too, but I am disregarding that for this example). So if your car needs 20 horsepower for steady, 50 MPH, it takes 180 for 150MPH.
Add in rolling resistance now, and drive train friction and you are just over 200 HP. There's your SVT territory.
170HP ain't going 150 without a 50 mph tailwind and downhill run. FWIW and IMHO

So does your clutch Slip?

IIRC realest car was doing some crazy good 1/4 mile times by his accounts. Maybe there is some validity to his claim?

7K RPM in high gear is mighty fast...

.......over 150 MPH?

He has to have more than exhaust and intake, must have a turbo or sumtin' to do that kind of speed...

Chip too, as rev limiter would be kickin in..

Not too many people can go 7K RPM in high gear..

Anyone else here hit that? (Non 3L, Non Turbo)??

Well I know what I saw and I know I was doing over 125. I guessed 130. Besides speedos and Tachs are hardly ever correct at high speeds but I know what I saw.

I'd believe 130.........

That was what I guessed, by how I was passing people doing 90 and it looked like they were standing still and by the RPMs. I think everyone should wind out their Tour atleast once like that. On the track of course.

I recall Sam (Phat SVT) doing 160mph once in his SVT. Of course, thats what his speedo said, and they figured out that it was probably around 152.somethin'. Course, he's got one 'o 'dem vortechy blower thingys on his SVT... Contour I think it is.
