Originally Posted by chiromikey anyone care to answer a question that has been asked twice now... The vbox/pbox is a data logger.

After a certain amount of time it will create a new file (graph) and start the data logging process over again until you run out of space on the flash card (which is pretty hard to do...but you can delete the old files once you have read the flash card and saved the runs onto your computer). Since it is a data logger, and you can do the analysis at home, there is nothing special you need to do to get a 60-130mph (aside from making sure you pass 130mph). However, if you don't put the flash card in, you would have to set the vbox/pbox up to do a 60-130mph run....which it will only display on the small screen...but it will be lost forever once the power is turned off. Those runs wouldn't count anyway, as there would be no way to confirm the slope of the run without having it saved on the flash card where that information is stored in the data logging. Tom

My Pbox should be arriving next week. Can't wait to see what kind of numbers I can pull off.

Does anyone know how accurate these are at measuring 60' times? I'm curious if it can be accurate/consistent over a relatively short distance?

They are not exactly comparable to the 60' time measured at the track. The GPS measure "exact" 1ft roll-out, whereas if you stage deep at the track (as I try to do) the timing doesn't get triggered until the front wheel rolls out past the staging timing light. Here is a sampling of 5 runs from my car made at the track while simultaneously running my vbox:

Timeslip 60': 1.727s vs vbox: 1.98s (Drag radials)
Timeslip 60': 1.706s vs vbox: 1.97s (Drag radials)
Timeslip 60': 1.730s vs vbox: 2.04s (Drag radials)
Timeslip 60': 2.167s vs vbox: 2.49s (Stock Tires)
Timeslip 60': 1.994s vs vbox: 2.39s (Stock Tires)

As you can see, the timing lights lag behind .25-.40s compared to the GPS based vbox. I would speculate it is mostly due to the how deep you stage at the track.

Can you bring the vbox to the track on the 30th? I'd like to see what kind of 60-130 times I can pull

which track on which 30th?

not sure if Tommy Boy is coming or not (he will give in ) either way I will have the VBox

I will make sure that the vbox gets to the track (not sure if I can get away from work yet). It might make sense that you bring your own SD memory card (under $10) so you can take your data with you when you leave the track and use a card reader at home to analyze the data. You can download the "performancetools" software from this website:

i see, I didn't realize 60-130 tests could be run at a drag strip. i was thinking more like air strip

thanks

Thank you for posting up your data. Seems consistent enough to at least let me know if I'm improving. Hopefully I can try it out this weekend.

Ok I will go buy one if I remember lol. Thanks

MIR has a long runoff. I expect to be trapping close to 130 in the 1/4 anyway

So wait...

Does the Vbox automatically start the clock at 60mph and stop at 130mph or do you need hit some sort of "GO" button on it when you hit 60?

Forgive my ignorance with this unit.

It records your whole run and then you calculate your 60-130 later

Can't believe I didn't put that one together. Some engineer I am. Ugh. I did grow up near power lines, ya know.

learned something new again. I would consider a 60-130 test a run that started at a steady-state speed of 60, not one that was accelerating through 60. Now I see why this will work at a drag strip, i guess you keep going until you hit 130 rather than the 1/4 line.

thanks again

No problem. One would think it would be a steady state 60 to 130mph but it isn't.

I would say your drag strip time will be marginally worse 60-130 as you would have a fraction more heat soak built up before you hit 60... gunning from 40 roll would probably be the best as long as you dont get wheel spin...

Also, the specific track (MIR) is virtually flat. Some of the best 60-130 times come on a slight down slope but within the 3% decline stipulated by the 60-130mph powers that be...

I didn't read entire thread above but, anyone use this Vbox for extrapolating 0-1mile data I.E. like the texas mile? (I know Dragstrip isn't long enough etc) But plenty of daring peeps on here have posted 170-200mph speedo vidz, any 1 milers out their try this w/Vbox on E55/CL65/600 etc?

Good afternoon Mr. Banner....I never have, I personally dont like to go that fast and it takes a lot of road for us in our area...I dont think I have been much over 180ish, although quite smooth its very dangerous as any corrections at this speed are quite tough and on public roads wrecks can be catastrophic....just my .02......man did I just sound old?

Phukin A you did, you spikin' that 600 w/Geritol these days gramps mr. Banner For your information, I've been practicing Pilates & Macramé Serinity NOW!!! Muther Bit_ches

[mthis]

this is great. i have to get my self a vbox.

[nrgy]

ARGH! I went out to find the perfect empty private road to make my run, but I ended up letting off at 128.9 MPH I was just going to abandon the run as I thought I only clipped past 120, and the road was a little too bumpy for my liking, but if I knew I was only 1 mph away I would've stayed on it. I was too paranoid to try again (every worst case scenario running through my head), but at least got a good vid clip of it. I really wish there was any empty airfield around here.

use (M) M goes longer in 4th gear sport switches before 130. (M) 134MPH

i have a vid of mine in my vid mess in youtube check it out.

I finally got hold of a Performance Box and headed towards Mexico. My place in Mexico only allowed one run last night and the results were less then desirable. I had my brother in the car and started the run from 20-140. I spun all the way past 65 with ECU cutting back right around 55...totally sucked. I ended up getting a 8.4 but I guess for my first run it wasn't that bad. After this pass I noticed a helicopter patrolling the area and decided not to take any chances with the Mexican Police. I'm a little disappointed with my times but it wasn't a very clean run at all. I also noticed that my 100-130 time was right around 4.4....this isn't that great.

I'm not sure what the numbers mean but I decided to wait for the track to get some accurate numbers for my car. Things are getting a little too risky around Mexico with a few racing fatalities this month. I was really disappointed that I couldn't get my car to hook on my first run. I honestly believe I'll be in the mid to high 7's during my next track event...we shall see.

Wow...an 8.4s time is pretty good for your first try. BTW, I tried calling you a couple of minutes ago.
