Exhaust blowing is what has made Red Bull so dominant the last 4 years. They have/had got a better grasp of it than anyone else.
Does anyone else think this whole Exhaust Blowing Aero is complete garbage? It does nothing for the enjoyment of watching F1 unless your a big Vettel or RB fan.
If that diffuser had the effect claimed in the various reports linked here, why don't we see Webber constantly on #2?
Ferrari admit trouble's are more than tires. No shock but at least they admit they made mistakes. Korean Grand Prix: Tombazis: We can?t just blame tyres | F1 News | Oct 2013 | Crash.Net
From the BBC an explanation of their airflow at the back on the Red Bull CRUCIAL DEVELOPMENTS AT RED BULL-- BBC Sport - Korean GP set-up guide: Lewis Hamilton needs to return to form All the talk at the moment is that Red Bull have made a big step forward with their car, but I do a lot of analysis of the lap times in F1 and according to my calculations they have not moved forwards. They have stood still relatively compared to the rest - but at the front. I work out each driver's and team's off-set to the absolute fastest time of a weekend and in my latest data-set Red Bull's is the same as it has been all year. When someone else has dropped back a bit, it's not that Red Bull have done any better, it's just that they have done a very good job every weekend. I do these numbers as an average for the whole season and for each four-race chunk. Italy was the fourth race of a four-race block, also including Germany, Hungary and Belgium, and over that period Red Bull were no better or worse than before. They've just kept up that same strong overall consistency. If Vettel continues his dominance in Korea and beyond that we saw in Singapore then certainly they will step forward statistically, but it would be wrong to adjust the data-gathering period just because one team happens to have dominated in one set of races. There are too many variables that can skew the data in a small sample. Having said that, there is no question that Red Bull have been extremely impressive in the last three races. Play media Fernando Alonso of Ferrari drives during the Korean Formula One Grand Prix 2010 Korean Grand Prix highlights They have made two significant and inter-related changes to their car which are almost certainly at least partly responsible for this - one to the vertical vanes on the floor in front of the rear tyres; and another to the shape of the trailing edge of the diffuser, the upwardly-curved part of the floor at the back of the car. The vertical vanes on the floor, which direct the exhaust gases towards the critical area between the edge of the floor and the rear wheels, have been modified, with the intention of better directing the gas flow and giving it more energy, thereby increasing its ability to produce more downforce. Meanwhile, the outboard trailing edge of the diffuser has been shortened and made more curved, the idea being to enable the airflow coming off the diffuser to interact with the low-pressure area behind the rear tyres. Making the floor shorter in theory reduces the downforce it will create. But if you can get the floor to 'talk to' the low-pressure area behind the tyres, that makes a big difference and increases downforce. The idea is to turn the airflow coming off the diffuser outwards towards the rear tyres. If that airflow can then connect up with the low-pressure area behind the tyre it will speed up the under-floor airflow dramatically. So instead of the underbody downforce being created by the diffuser simply expanding the airflow coming through under the car, the low-pressure area behind the rear tyre is also sucking the air through the diffuser and rear part of the car, making it faster and therefore creating more downforce. Lotus pioneered this solution last season, but as you would expect Red Bull appear to have taken it to another level. Former Jordan, Stewart and Jaguar technical director Gary Anderson was speaking to Andrew Benson
Guys, do you remember when Paul Hembrey from Pirelli said that if we go back to the 2012 tires after the Silverstone race, it will give the Championship and the Races to Red Bull? As they will benefit most? It seems to have hurt Ferrari, Lotus, and Force India compared to the beginning of the season. LDM has also stated in the past his dislike for the level of Aero at the moment in F1, as opposed to letting the Engineers working in the Engine Department get on with it. Frankly, for the first time in 30 years, I could care less about F1. I just check the stats, if Vettel won, I don't even bother watching any longer. Wonder what is going on with the TV Ratings right now? I sure hope that the Exhaust Layout for the 2014 prevents this whole Blown Diffuser Crap from entering the picture. In fact, wouldn't it be much more exciting to see the return of more Mechanical Grip and Engines that overpower the tires, than this racing we are seeing today? Who cares if Adrian Newey finds a more efficiency and it makes the racing dull? Just a few thoughts IMHO as an F1 Fan.
Single central exhaust pipe exiting 17-18.5cm behind rear axle line and 300-525mm high - This should negate aero exhaust benefits. 2014 Rules: First Look | ScarbsF1.com
The tire change handed the titles to Red Bull. Ferrari kicked their asses in China and Spain and Red Bull got on their little soap box to complain. RB now plays the politics game way better than Ferrari, and it's a shame. Would have never happened under Todt and Brawn. Remember back to Silverstone 2011? The blown diffuser concept was banned for that race. Ferrari wins easily, then allows the blown concept to come back? Would have NEVER happened under the "old guard"
You are absolutely 100% right. I don't get it either, is it because of the money that RB is pouring into F1 by owning two teams and being a sponsor of the upcoming A1 Ring? Is it the fact that Bernie has asked them to sponsor the NJ Race? Under previous Ferrari Management, remember the 2003 Michelin situation, Todt let it be known in the strongest way that Ferrari would protest unless the changes took place. Is it that Domenacali is spineless? Ferrari should have never let the Tire Changes take place in the middle of the season when the F138 was so strong on those tires. Shame really. I honestly respect Vettel as a Driver and what RB has accomplished, but frankly I would rather not watch it. I could care less....
Spot on. That is exactly what I'm talking about. 2013 has been one of the most boring seasons ever, which is a shame since it had a lot of promise at the start of the year. Suddenly we had the tire change, illegal tire tests that received a slap on the wrist, and it turned into a bit of a joke. Personally, I think part of the problem in all this is that Vettel is Bernie's new golden boy. Just look at how the two schmooze it up after Vettel won his WDC last year. Bernie in his trailer, right by his side, etc. Red Bull has been found with too many devices on their cars of dubious (at best) legality and nothing happens to them. Flexi wings, their illegal floor and wheel nuts, ride height adjustment, and it's quite clear they are STILL blowing the diffuser which is completely against the rules yet the FIA refuses to clarify. Frustrating, but Red Bull has the political game on lock. The fans know all this and coupled with the bending of the rules, it's a big part of why Vettel gets booed. Other dominating teams or drivers never got booed. I think everyone is tired of Red Bull.
Of course Webber doesn't get the trick diffuser/engine mapping. His car was allegedly sounding as nothing strange in fact.
To have 50% fewer chances of being caught? And because Webbo is on some kind of internal gardening leave and can't keep his mouth shut? I'd do the same.
What's more likely is that they're actually using special mapping (again) which cuts firing to cilinders (effectively making it a 4 cilinder at times) as an alternative to traction control. Entirely legal.
just clever mapping really. What it does is smooths the delivery of power out of corners. Innovative but nothing others can't do.
Excuse my ignorance, but isn't the mapping done within the ECU? I know I'm missing something but don't know what.
