In theory it is possible. I'm not really sure of the situation where you would have excess boost under maximum acceleration though.. but it should be possible.
MGU-H transfers recovered energy in KJ (not kw), and that energy is unlimited. Doubtful anyone actually recovers enough to reach K 160 bhp limit. ~90kw was a number thrown around some time ago.

Highly unlikely anyone has more than 120 kW from the MGUH. I did some calculations earlier in the 1.6 thread - can't remember exactly but it was well under 120 kW. The only way would be much higher boost and higher compressor and turbine efficiencies. (I assumed 80%)
This.
The transfer of energy as time flows is called power... Read the article... power is the word used her and that does indeed make sense. Energy itself is nothing without power. all the sorts of things that transfer energy must be rated with time as a factor.. (How you derive the ampacity of your cables, your cooling system and such).
I only plucked that horsepower out the air for the sake of argument but I can do some rough and dirty calcs if you want. Going by the backpressure you would not want to see, the power that the MGUH sends to the KERS and the Energy store would definitely be less than 160hp.... I just threw the number out there..
A typical turbo for your average 300hp sports car needs 70 hp to compress the air... A dirty calc.. assuming the 1.6L engine is around 320hp without turbo @ 12,000 rpm the F1 turbo would use need around 150hp or so just to compress the air for the engine to bring it up to 620hp or so (you can do a quick thermodynamic calc too using air pressure ratio and AFR if you want, but this way is shorter for me!). That is it's primary job with these regs to power the engine and then the ERS is second- (i think!) So one can easily conclude that the additional power from the turbine that is drawn off for the ERS must be much less than this 150hp.
