That is what they say in that video ;)

we ve seen that 1mm at restrictor at grN evos is about 20 bhp.
go figure that with this cheating, the air mass could inlet to turbo, was much much more, than from the difference of 2-3mm at restrictor ιincrease.
It is a massive difference,and no way drivers couldn't understand/feel that their cars suddenly had a huge power increase.
ie...
32mm restrictor evo = 300 bhp
33mm restrictor evo = 320 bhp
36mm restrictor evo = 360 bhp
FIA technical man in the studio say they increased the restrictor with 25%, theoretically increasing the engine power with 40BHP.
As I say, this what they say in the video, I haven't got the technical knowledge to agree/disagree :)
Except Toyota engineers at that time nobody knows exact values, but for sure it was a lot of advantage. And very nice trick.
10 months until we see Kalle's WRC debut? http://www.autosport.com/news/report...enough-for-wrc
About Kalle. I was thinking, where in Europe (except Latvia) can driver of his age compete with top machinery like R5? In Czech republic can driver compete in "Youth cup" for drivers between 16-18 years, but only with slow 2WD (like old N1 cars) and if I remember well, there was chance to drive in GB when you were 17, but I´m not sure. Thank you :)
