if they are only using half of the allotted 400KJ for use with their button activation, that gives 3.3 seconds at 60KW
the other energy then being directly fed into the drivetrain is 200KJ. Now to eek that out for the remainder of the lap (lets assume 30 seconds as a reasonable time for total accelerating around a circuit) then that is only a power increase of 6.6 KW. Which is a fairly negligible power increase, certainly for the Renault RS27 which is rumored to be down on power by ~60 bhp.
However Renault have announced that they have gained ~ 20 bhp from not hot blowing and other reliability modifications, As RedBull only ever used Cold-blowing, they might have had a significant power advantage over teams who were hot blowing.
1. I always heard the RS27 was more like 15-20 hp down MAX
2. That Red Bull never used hot blowing is a myth IMHO, listen to their engine last year(the overrun sounds as rough as anyone's), and Renault have bragged that the RS27's fuel efficiency offered an advantege for hot blowing.
