Hmm, wow! I hadn't seen this thread until just now (saw the link in the newb(ish) thread about adding multiple ports to an engine). That's sickly fast for an FD!!!

Now to look into procuring a VBOX so I can see what my car is *actually* doing (when it runs... lol).

DO IT!

I wish more people would get real and buy a VBOX.

I am happy to run calculations for anyone who sends me their VBOX files ;) Hopefully we can start a trend of real testing :auto:

Cheers man,

Do you know how much the VBOX III runs? Honestly the only stuff I saw prices on were the driftbox and stuff like that...

First things first... Get my car out of the shop, then I'll look at picking one of these up.

I assume you need the actual weight of your car and all that stuff entered into the VBOX for an accurate reading?

I use a Performance Box by Racelogic (same company that makes VBOX). It is an external device that mounts to the windscreen via suction cups. Me and a buddy split the cost of the unit and use it to log our times when we do track events.

You can use it for the acceleration tests like RICE does, but I have yet to log one myself.

^ Hmm... that seems very interesting. I bet you could also use that on a motorcycle... Does it have an internal power source, or do you have to connect it to a 12v in the car?


:edit: Also, will you be bringing this with you to DGRR? I'd love to snag it for a pull or two to see some solid data on how my car looks on paper!!

It uses the cigarette lighter for power

I had a VBOX III it was $22,000 from memory.
I now use a VBOX3i I can't remember the exact price but is around $27,000.

You don't need their top end unit though. Racing Beat use a VBOX II for chassis development (it's around $8,000 or so). But you don't even need to spend this amount.

I started out using a VBOX Mini > read here > http://www.ausrotary.com/viewtopic.p...66bc9be8914e1c

As I did more and more work I stepped up to the VBOX III then the VBOX3i with IMU unit and a whole host of other input boxes.

The VBOX Mini is copied in a hobby format in the Drift Box and Performance Box models, these are used 99% in the performance world *these are great products and do most of what you would ever need* These units from memory are sub $1000 or so. The VBOX Mini is around $2500.

These are THE reference measurement instruments across all vehicular platforms around the world and in so many testing labs, EOM's research centers etc etc ............ Buy a drift box or performance box it will be the best money you ever spend

Yes to calculate the power as I do (see here > http://www.riceracing.com.au/vbox-ii...ing-tuning.htm )

(I developed this formula from first principles myself) and use it on any RL .vbo or .dbn file to add a maths channel with power as the output (as I did for the dude with the fast fd)

you need to know the mass of the vehicle as run. I measure all the cars I test with my Tanner scale system.

Anyway read this > http://www.performancebox.co.uk/down...CHvPB_Test.pdf

And here is a good thread on Race Logic own site > http://www.racelogic.co.uk/Forum/showthread.php?t=727

Right on Peter,

I didn't realize they were that expensive! Lol, I went to the VBOX USA site and saw the capabilities sheets, but no pricing data. Now I know why! Lol

Will have to look into picking up one of those along with the new ecu this summer, lol

For $12 this application works amazingly well.

What did you enter for drivetrain loss? I'll just leave mine at 0.

I pretty much despise anything apple (except my ipod, but that's just for sleeping/working out anyway), so I might be needing to pass on that one unless I can get it for my droid by way of Verizon.
