0-60 time

[Shoppinit]

How are you getting on with the repairs?

[JCviggen]

OK I hope lol, it's at the mechanic's now. Flight back home tomorrow and hopefully I can pick it up tomorrow eve after phase 1 (IC sealing, venair hoses, replace MAFs, N75 and DVs along with oil change to 505.01 5w40 now that winter is gone) so that monday I can go for mapping. Wednesday is a trackday at the Ring and maybe I'll take it out there for a photo op, driving a volvo on track. After that I'm back to Russia for a week and i'll give it back for doing the alternator/timing belt/suspension if it ever arrives.
And I'll have the ATF replaced by OEM stuff since they used their own "compatible" fluid at the Shop and who wants to gamble. That's another 120 quid worth of oil down the drain.


I also picked up a set of PS2's (non R01) to be fitted when knobbly has been removed. Will be nice to get the sottozero's off.

You can save some money by getting the same stuff from peugeot or citroen. See my topic on useful information for part numbers.

Fantastic tyres. You won't be disappointed.

[JCviggen]

Yeah I saw that, in the end I just went for what I could buy online since I'm abroad...PITA constantly being away from home.

Did get a good deal on the OEM stuff through a german website, about 10 pounds per litre and free shipping. Just my mechanic wanted 13 litres to use some for flushing the other stuff...

Tires I found on Ebay germany, slightly used but near new set of 4 @ 7.5-8mm thread manuf. 2009 for 450 pounds.

Evo mag recorded 0-60 in 4.8, but that seemed a slow time to me.

Also, all those moaning about the guy driving to 60 with one hand, get a life. 4wd car and if you can't drive it to 60 with one hand you need to go back to driving school

One-hand is fine.
Moan switched on... BUT, One-handed + ESP off + full throttle + one eye on binnacle + stopwatch button = much criticism and a huge fail waiting to happen... Not the smartest thing to do no matter which way you look it, now take your medicine... besides, that was months ago, now we all know Mavada is stupid we don't need to criticise him openly anymore.

Last car I 0-60'd was my Mazda 6 MPS, highly tuned with a 3071R bolted on, it managed a this below on the dashdaq, a great tool by the way , it uses a simple stopwatch that starts the moment the car moves and stops the moment the speedo reaches 60mph. Good for 4wd as no wheelspin to create a false reading.


sold the bloody thing before it brought the 6, wish i hadnt

@JC, yes the Performance box is a GPS based tool. I have not looked into the technic of a GPS antenna, but it is quite sensative: as soon as I drive under a bridge it will mention loss of GPS satellites. So I would think the accuracy is pretty good.

About the Vagcom and the 0-60 run...: how does the Vagcom get the speed indication?
the NAV gps? Will the audi GPS be as accurate as the PB antenna?

Thanks Bam Bam to let me know on behalf of all the users on this forum im stupid.
So you think you can speak on behalf of all the users without really knowing all of them have the same thoughts...
Smart guy.

Maybe interesting to know i did it on a 10 meters wide track without traffic, corners and on a dry track.
You dont have to look at your stopwatch while doing it, just push the start button when start accelerating and push the stop button when reaching 60. if a had a car with 4 spinning wheels on full trottle yes that would be stupid.
You dont have to look at the dials the first 4 seconds because it wont reach 60 in 4 sec.
And as said before, go to a drivingschool if you cant do that...

[bam_bam]

Juicy what have I missed?

So, this driving school, where they teach you how to 0 - 60 launch with one hand and a stopwatch, where is it and how much do they charge?
It sounds like a strange discipline and I've never seen that offered on any driving course before, sign me up...

Mav - I was joking. I was saying you're accepted in my own retarded way. You've become a great contributor and I like you.

However, you're wasting words on explaining how to time a 0 to 60 with a stop watch, it's not rocket surgery, we get it! Although you may as well give up now, knowing that you'll never convince all of the users on here that what you did was safe or 'smart', why? This is a forum based mostly on opinion, it's not the real world.
That said; IMO - It's accepted that full throttle, no TC, one-handed and less than 100% concentration (stopwatch operation) 0-60 runs are, waaay riskier than performing the same task, with two handed control and no stopwatch operation. Let technology do the timing.
You could argue against it all you like but it ain't gunna change a man's opinion.

Personally I don't really care what you do with your car and a stopwatch but you must admit, posting your escapades on here does leave you somewhat open to opinion, so just eat it up and do what you want anyways.
It never really stopped Mooch doing what he wanted, he entertained most of us and divided the rest. It didn't bother him none, he'd just take it and move on. It's all just words.
Just think of it as us giving you a "told you so" before anything has happened and may never happen...

Here's one last thought.
Given you had to stand at the 1/8th mile marker on a ten metre wide drag strip, with nothing but a string fence to 'stop' a launching car mowing you down. Would you be more comfortable with;
A. The single handed stopwatch user
B. The two handed control freak

It'd be interesting to see what odds the bookmakers would offer too.

Rant. Over.

It's not about sensitivity it's about the speed calculation. (actually if sensitivity was really good you would not lose the signal under a bridge) If you look at the acceleration data as a curve (speed) it will go up very steeply at first and then level off slightly. Here and there you will see little peaks in the curve. If one of those peaks happens to just cross a speed point then you get a time that is several tenths better for that interval, but you lose it on the next one because you never really gained the speed where the calculation had a little hiccup. With GPS it is unavoidable because of the update frequency that is not entirely in sync limited by the GPS signal's own baud rate. Complicated I know but trust me I've done it a lot

This really only happens less than 1 in 5 runs, so doing multiple runs will clear it up.

Had me chuckling big time, but I knew where you were coming from. The written word is easy to misinterpret at the best of times and when you chuck in a language and culture difference I can understand why mavada got the hump.

For the GPS thing, its accuracy will probably be about 5m. On a 0-60 run you'll probably cover about 80m (can't be bothered to work out the actual number) so you're looking at a calculation error about 6%. The further you go, the more the error is absorbed and the more accurate the reading is.

Unless it's a very recent (and expensive) GPS unit then it's accuracy is more likely to be 10m than 5 making it even less accurate.

Has anyone tried this app http://www.dynolicious.com/ ?

[Shoppinit]

Yes. It's like the g-tech but about 30 times less accurate.

All fascinating stuff but personally I prefer the video approach.

Just mount a video recorder (or get a second person to hold it) where it can see the speedo and any GPS speed measuing systems (eg speed camaera detector), then do the run, and track the launch point and 60MPH on the video using the timer. Since you can see both readings you can also make a judgement about instantaneous differences in the readings etc.

I think there is alos a facility in Vagcom for those with the equipment to measure using the car's systems.
