Av you lads been down the pub at lunch??? ;)

I have - so, are there any downsides to having a skinny, non-existant ar$e? Or would this be an advantageous "ass'et" ?
01 RS4, Milltek, Dahlback Racing rears, RS6 fronts and a few bits to be added.

Also, as I hate driving, my toy to play with - a Honda CBR F Sport

If you had a 12v dyson in the car and turned it on would this stop the doors getting sucked out?!!

John
If any thing i would expect it to potentially add to the pressure as the air leaving the cleaner would be at a higher pressure than the air being sucked in to the dyson inturn sucking more air into the car from outside as it would be acting like a turbo but with no proper exhaust to the outside of the car

Dr-Al feel free to add the full white paper science explanation on pressure build up

Pup quiz
I think it's illegal to interrogate young dogs - RSPCA may get involved......

Probably okay for Al seeing he is a Doc, now why would Philip want him to interogate dogs, makes you think him being a Doc an all :wink:

Not sure about other folks, I only get the noise above 140mph, sometimes it only starts at 150+.

Is this in hot or cold weather as the outside atmospheric's will also affect things.

If it's colder outside the outside pressure is colder combined with the hot air circulating inside the car from the aircon creating a greater pressure differance

The lower the car is would also have a effect due to the air being colder nearer the ground due to hot air rising

A mixture really, it seemed to do it less at vmax (34c).

that would be down to hotter weather and higher atmospheric pressure's and that fact you probably had the aircon off or on cooling lowering the cabin pressure

Don't do pub quizes - too many sports questions for a geek like me

Anyone attempting this should avoid the use of thumbscrews. The canine species lack opposable thumbs thus rendering this tool ineffective as an interrogation device.
