Stummel,

Yes, 60-130 mph.
I think of them as Clydesdales due to the torque.

After reviewing the data my 5.37 time for 60-130 was on a downhill, so I'm redacting that time.
I will leave the 6.60 as my posted time.

Hey Jim, 6.6 is really fast! Are you able to record the run and email me or Jean the data file from the camera card (plugged into the front of the AX-22 operating in continuous mode)? Then we can add it to this collection.

Woodster

anything under 9 is good,
under 8 is fast
under 7 will flatten your eyeballs,

Be careful, Jimmy!

Jim has shared the data with me, however he is keeping the equipment a couple more days to do more runs.

The runs were done in timed mode, which seem to be very prone to errors. All the runs must be done in continuous mode as suggested earlier.

I will write to Race Technology about this.

So are you saying the data you have in timed mode looks incorrect ?

Have to say IMHO 6.6s for 1578kg 4WD does look a bit unlikely - unless the Andial uber torque lump has been substituted for a qualifying grenade special

Jean

Yes, it seems like this way of timing (set speeds from: to: ) is very sensitive to tilt and calibration parameters. I just shared the findings with Jimmy the felon.

JJayB is going to try the "continuous" mode instead, when he gets a chance and right place. I expect the results to be quite different.

Not just dyno's that have potential set-up errors!

You haven't heard of NOS.

You are spot on I did think a lot about this, however it remains a great tool (accuracy/simplicity) to compare performance between users across the globe, with some marginal errors or correction factors for temps etc..that can be accounted for. I personally never had any errors with it. Next step will be integrated video with the AX22 data.

These words from Konstantin say it all. ( I took the liberty to correct his misspelling)

Felt like i'd just inhaled some when I read those numbers

Scepticism is healthy- not to sure about cynicism though! I have been watching all the various debates with great interest . I have a reasonable amount of experience with dynos(as a customer)and have been involved in debate for a number of years- not quite on a worldwide scale however.A lot of dyno know how in my part of the world and customer expectations and the industry serve to add to confusion.
The parts I have found interesting in recent times-- an outstanding 1/4 mile time in Bahrain generally thought to be suspect( no fault of guy who did time and posted on a forum) and anaylised from every which way as not possible.So that method of comparison goes out the window.
Now it seems even the AX22 needs to be used diligently to get accurate result.Did I also see the video could not be relied on to be accurate?
I will soon be able to compare performance numbers on a number of relevent cars and engine types and it would have been great to have had a foolproof method. Come to think of it-- there is one. It's called RACING!

The AX22 is the most accurate means we have for comparing cars over the Web when it's not possible to race. To be sure the AX22 is accurate:

1. Always calibrate from a complete stop.
2. Use only the continuous timing mode with data recorded to a Compact Flash card and then plotted using the AX22 software.
3. Be sure the AX22 is reading 0 MPH when you're not moving.
4. Be sure the AX22 is level and pointing straight ahead.
5. Be sure the AX22 antenna has a clear view of the horizon and is mounted securely, preferably in the center of the roof.

Note that the raw AX22 data contains detailed location data, so you may only wish to share the plots over the Web, and not the raw data.

Bill,

With a large flash card (1-2 mb) can I store 100 miles of fast running? I would like to archive two fifty miles legs of an open road race I will be running.

Comments please!

Cheers

Roland

Roland, a 2GB card can record way over 2 hours of runs, so if you average 50 mph, you would still be fine.

Edit: In fact I just checked, a 10 minute run was only 1.9MB.
