I heard that the SVTF has a top speed of 130 because the compter limits you to that. I saw someone else on hear saying they hit 160, how is that possible. How can the factory speed limiter be bypassed id like to at least try and get to 140 once.
SVT Focus top speed?

I've had mine to 138mph on lowes motor speedway. But I always seem to come up on lap trafic...so never had her wide open yet. And when I was doing 138 I was in turn N-3 and N-4 (N= Nascar)
Im gonna try again this year at the Hyperfest, but hopefully with a supercharger

If your car topped out at 130 and wouldnt go any more, you shoul dhave the motor looked at. You should be hitting 135 - 140 - 145 stock.

Gotta love top speed... dyno runs.

I've heard the gearing would allow you to hit 160 something before redlining, but unless you have some serious power, drag is the killer.

Wouldn't really trust speedo, especially with non-stock size tires.

Use this and punch in your numbers. I have 1.08 6th, with a 3.08 final. 24.5 inches Contis. I get 6588 rpm @ 145.
What size tires are y'all using? 6200 with our final drive isn't quite 145 with 215-45 Conti's. I've found banking really saps power, especially in upper gears.
We had this discussion several months ago. Physics being what they are, 145 lb ft of torque at 5500 kinda limits what we can do top end. I think 134-136 on level ground, alone would be about all you could expect stock.
At VIR last fall, 112-115 on front straight (fairly long) was about it in 5th, couldn't pull any faster in 6th (see torque). TurboTom with 2 x the horsepower/torque was in the 140 range.
Remember torque is what gets you up to speed. Horsepower is what keeps you there. (function of rpm-torque)

Haven't found a formula to factor in testorone levels and how that affects Top End.... yet.

I count 145mph or 233kph....not that I recommend trying it...I'd rather hit 1g in a corner on the track than 150mph on the street

Doesn't anyone else realize this is a gauge test? The foolish photographer took pictures but left the milage the same.Reaaly? This is what mine looked like, I can figure out what it says....![Image]()
