Any guesses?

That’s right.

OK, yeah, hefty tailwind...

This one was going cross wind though, any explanations? For the record “normal” would be 6.8-7.2 seconds. I have my theory but I’d like to hear from someone that knows better

I could do it faster

Down hill, better than stock tires, and you used an app not a calibrated piece of measuring equipment?

GPS update rate, error, and jitter.

I’ve used the same app and got similar garbage results. Some runs were quite plausible others in the same location under the same circumstances were clearly physically impossible. It just doesn’t work.

GPS is accurate for speed over distance, but in a short space it’s useless. It’s actually kind of amazing it gave you any remotely close time, that speaks to good software, in my opinion - it probably eliminates the occasional outlier data point.

The GPS nav I had in an old Kenwood head unit used to always have hilarious “Max Speed” data points. For my 2001 Suburban, the Max Speed was usually in the 800-900mph range. I’m sure there’s a term for this. [edit: I see below, someone calls it “jitter” - sure, that sounds good]

1.2 seconds quicker that a CR-V.

With this logic, a Vulcan v6 Ranger should be laying down a solid 5.1 to 60. Raptor beware.

There’s a road I use sometimes that gives me consistent results with about the same drop. Runs in either direction don’t vary by much (camera on speedo method confirms this).

Better than stock... they’re snow tires but the stock tires were utter shit so maybe. My 7 second runs were on snows too.

The app is admittedly the weak link but it seems to have been reasonably accurate up until now. Even with error allowed it seems quite quick. Of course it could be far more out of whack than I thought

Seems to have been pretty good until now. Of course, GPS can cast a fairly wide net

Maybe I just haven’t done enough runs and got lucky, up until now it didn’t seem too bad.

Is there another you’d recommend? I’d imagine it’s a limitation of the system as much as anything

My Ultragauge does 0-60 times too... problem is, my 1-2 shift chirps the tires. When I used it I got something ridiculous like 5.5 seconds, which I imagine was the moment of upshift. Haven’t used it since.

I should have used that yesterday, the wind was coming so hard the tires weren’t even close to breaking loose. Quite a comfy shift, actually.

About 5.5 seconds. Don’t forget the Raptor gets the same boost. I’d be curious to know whether more aerodynamic cars get less help from the wind than pickups (probably) and how much.

I heard the wind was gusting around 60+ knots. In other words... literally no aerodynamic drag.

If the samples aren’t taken at tiny fractions of a second, there’s got to be some interpolation or guesswork.

The only GPS I use for speed/distance is for running and hiking. As soon as the signal gets weak under the trees, it goes a little haywire trying to fill in the gaps.

I’m honestly curious as to how much effect a 60+ knot tailwind would have on a more aerodynamic shape.

This is fair enough. It’s been fairly good up to this point. And in any case, it should be at worst within a second. I guess the second one is fine

I had a friend in college who used to drive his GMC Jimmy around in 4-LO all the time in the city, using it to beat literally anyone off the line, up to about 30 - I don’t imagine he had much success beyond that speed.

He also blew an engine, which was kinda hard to do to that 4.3.

Videotape your gauge cluster an see how long it takes to 60, though speedos can be fast sometimes. A wireless obd2 reader should be able to log it aswell but it depends on the program you use on your phone

One thing the 4.3 didn’t like was revving. One thing he would have done in 4LO was rev the shit out of it.

I’m amazed he didn’t completely shred the driveline leaving it in 4WD all the time.

I did that a year or two back. Best result was around 6.8, worst about 7.1 seconds. I also verified it by pinning cruise control to 100km/h and double checking against GPS... within 0.3 km/h iirc.

I have an Ultragauge too, but that seemed to pick up the wheelspin on the 1-2 change.

For extra accuracy you could look at the rpm and than do the conversions for your diff, tire size, and particular gear. Either way 6.8's probably what your doin
