I referred to cold blowing, something Renault engines use since 2008/2009. This has nothing to do with the blowing we've experienced in 2011. This cold blowing, which creates a similar noise like 2011, albeit by far not as present as in 2011, is what every Renault powered car still uses as Renault uses this for cooling the engine.gilgen wrote:[I doubt that Renault need to improve reliability, as their engine is almost totally reliable.

Strangely, this winter there is so much paranoia and gloating....those who want the RB8 to fail post apocalyptical things about exhaust blowing etc.....those who want macca to lose claim their nose concept is conceptually just soo wrong....and Merc is either a WDC car or the dog of the year again.
Can't we stay rational without panicking and finger-pointing?
It is not illegal to leave the throttle open when at idle or off throttle. What is illegal is to partially close the throttle coming off idle and then progress to full open throttle.Mr.G wrote:As i understand this, they need to use illegal opening of throttle valve to achieve the required bolwing efect.
It's "creative engineering" if you get away with it. It's "cheating" if you get caught.Mr.G wrote:Is this only loop hole, or it is cheating? As i understand this, they need to use illegal opening of throttle valve to achieve the required bolwing efect. I'm not sure if I get it right, but this wasn't capable to monitor, so they (FIA) wan't to update the ECU software to be capable to chceck if everithing is allright.Fredy4 wrote:The sport is all about using loopholes to be faster and this is no different.
If I understand it right this is from my point of wiev cheating not loop hole as there are regulations for the opening of throttle valve.
But maybe I understand it wrong. So corect me.
The very nature of that implies energy loss too. So you could argue that this type of exhuast has a compromise VS The exhaust that shoots straight backwards as seen on the RedBull. Of course it as all about how much is sacrificed to get the exhuast where you want it. Maybe Newey rather high energy in a not so fancy location VS low energy in a fancy location.Crucial_Xtreme wrote:When an exhaust jet exits into a cross-stream, the jet almost behaves like a deformable solid.hardingfv32 wrote:I wish to research what happens to the exhaust plume when it enters the atmosphere. What thermodynamic or aerodynamic word descriptions could be used to describe this activity? Using simple descriptions is getting me nothing.
