WRC have secondary air injection (antilag system)?

The ALS stands for Anti Lag System.Quote:

The boost check is done to make sure the launch control strategies are working and to check the turbo speed to make sure the entire system is working correctly.
The ALS on the modern WRC cars is called a fresh air ALS. (explained above)
How the 2017 Aero Revolution transformed WRC

I've waited years for an article like this. Thanks for posting!Quote:

About the first time Toyota is clearly copying rival teams when it comes to aero.
EDIT:
Speculation: The renewed interest (they evaluated this before Mexico as well), could also be due to the brake issues Meeke had in Argentina. The dust entering the rear brakes trough the lower entry point could have been a factor.
Testing this why Haninen is entered for Sardinia ?

Well, when they use a WRC event for testing, they can only use homologated parts. Mäkinen said in a Finnish interview thay they have many things to do testing for in the heat of Sardegna.Quote:

Didn`t M-sport state that they made a sole rights WRC deal with Sachs for 2019? And Hyundai (at least so far) only changed the tarmac damper supplier and it`s not Sachs...Quote:

Spoken with many mechanics in WRC/WRX teams, and the general opinion is it was not Sachs that was something superior in VW (both WRC and WRX) but VW:s geometry, for instance only for WRX they tested over 30 different geometries before they made a decision.
With a great geometry the demands from the actual damper is not as crucial as in a bad geometry..
EXT seems to still be involved with Hyundai: https://www.facebook.com/ExtremeShox/Quote:

At least in Riihimaki rally the damper bodies were EXTQuote:

For a long time I was regulary reader of this forum and now i have registration too, because i have a question :)
Does anyone know what is the purpose of the panels in front of the cooler?
Attachment 1785
They are used in too cold conditions (Sweden) to reduce the amount of cooling air flow, or when cars are not in competition mode (cerimonial starts and so on)
Thank you. I understand reason due too cold conditions. Using in non competition mode less. Lower power - lower amount of air?Quote:
