F1 » Horner: RBR rivals 'overestimate' benefits of blown rear-end

Red Bull Racing team principal Christian Horner warns any rivals who think they will be able to leapfrog the early-season F1 2010 pace-setters with their own exhaust-blown rear ends to think again...

It's now been reported that Red Bull have a special engine setting for Q3 that keeps the exhaust gasses constant to give it better downforce even in slower corners, and that the setting has to be used sparingly as it can damage the engine.. This would explain why they only show there pace on the last lap of Q3

Horner was right about rivals over-estimating the effect of the RBR ride height adjuster. In fact they overestimated the existence of it.

So this might all be hot air. Then again, if you can't build a F-uct, blow it out your diffuser.

The report about the special engine setting to keep the exhaust gasses flowing is hot air.
To keep the exhaust gasses flowing at a near constant rate which is the way to help the air flow through the diffuser means the engine revs have to be kept constant (high revs) the F1 engine revs (power band) drops down 2500/3500rpm.

go read any site etc dedicated to sports car design and the "blown diffuser" has been a pretty standard design step for a LOT of sports cars but most agree that the affects of doing so are negligible

I guess much in the same way RBR Over estimated the F duct??? Well if you look at the whole picture. RBR has their work cut out for them since they were not able to take advantage of the gap early on. That gap is much smaller now almost non existant in terms of race pace. The Blown Rear end cannot hurt the McLaren as it is already pretty much on par with the Bulls in terms of RACE pace where it counts.... If this gives them 2 or 3 tenths.... It certainly will not hurt their cause.. Mclaren has beaten RBR to the top step 4 times in 9 races without the blown rear end... So...
RBR cannot take anthing for granted especially given that they have a fragile car

i dont beleive that any other team is overestimating the rbr style exhaust, just as they arent overestimating mclarens f-duct, get both working efficiently on a lotus and they may be able to challenge sauber, williams etc, get both working efficiently on a mclaren, ferrari, mercedes or renault though and results may be different, at some races three tenths can cover up to six cars so it is all about getting the cars to be at least as competitive as the competition
