Hi guys!
Does anyone knows any site to give realtime timing from Bahrain of Jerez?

some kind of air flow monitoring ??
I would have to agree. Perhaps they will take photos of the paint ripples after a lap and analyze them. Clever idea.


McLaren's explanation:
"This is what we call a 'flow vis' (visualisation) - where we take a paraffin-based light solution and apply it to the car."
"The solution is light enough to flow over the car, drying quickly to determine the airflow over the bodywork."


McLaren explained this is a routine operation. "This is a common occurrence when testing new cars and is used to confirm the wind tunnel readouts."

Interviewer: The most exciting moment during the race weekend?
Kimi: I think it's the race start, always.
Interviewer: The most boring?

It's damned impressive that Webbo is that fast while still recovering from a broken leg!

I know testing really doesn't mean a whole lot but for us Webbo/RBR fans it sure seems promising for '09! 8)

I can't find Bahrain, but here's Jerez:

http://www.f1today.nl/live-update/2009/ ... -de-jerez/
F1 Today have times from both and is fairly frequently updated:

just click on the "live" link to the right of either Jerez or Bahrain.

The Bahrain one isn't Live but yeah, at least it's there.

Things are getting closer. * McLaren possibly with '08 wing configuration.

Yep, the Macca has its '08 wing on again:

I can't understand why they would do this in good weather? last time their excuse was because of the bad weather. :wtf:

They might want to check the differences to better understand what is caused by the '09 wing and what is caused by other changes.

What we do in law stuff sometimes, is to compare the regulations in different countries to better understand the differences. It might be just the same in terms of technical / aerodynamical developement and understanding.

McLaren's explanation:
"This is what we call a 'flow vis' (visualisation) - where we take a paraffin-based light solution and apply it to the car."
"The solution is light enough to flow over the car, drying quickly to determine the airflow over the bodywork."
At what point in the lap does it 'dry'?

What are the ambient conditions at the time it 'dries'?

Note - use of the word dry in inverted commas - as the viscosity will be changing right up to the point of 'drying' (i.e. eventually so viscous it ain't going nowhere anymore).

There are just so many variables to this testing 'method' that it reeks of desperation or a flat out decoy.
McLaren explained this is a routine operation. "This is a common occurrence when testing new cars and is used to confirm the wind tunnel readouts."
*snigger*

A common occurence when something is FUBAR.

What do they determine from that - there is indeed a front wing wake at approximately 5 degrees (give or take 2 degrees - or something similarly ludicrious!).

Without having exact control over the boundary conditions, the explanation given is bull. You'll verify f**k all in the way of wind tunnel tests from some paint streaks on a surface that changes direction all the time.

For instance - what happens when the car is going laterally at 3g? Is the paint not expected to move towards the outside of the car?
