Right, if the engines put out the maximum allowed amount of power (3 bar, 15000rpm) then they would run out of fuel well before the race is over. 3.5 bar boost (4.5x atmospheric pressure) is about ~3-3.5x atmospheric density (depending on intercooling), the displacement has been cut to 2/3rds and with the electric turbo there's no reason the engine can't hold full boost to the rev limit, so you're looking at about 1100-1200bhp + a little bit more from the turbine.
With this 100kg/hour rule, at 37% thermal efficiency you can't produce more than 633bhp, so at 10500rpm the cars will only be running maybe 1 bar boost, and there should be a mountain of torque well below that.
Drats, I really wanted to see engines that could pump out 1200bhp. These engines should be capable of that maybe with a little tweaking. Imagine they were driving around with 1200hp on tap but could only use like 600 average while accelerating, that would make things very interesting (aka a shitload of overtaking). With the current setup it seems like they'd pretty much burn through the tank right on time if driving flat out.
