What you said is true under a theoric point of view, but you need to clash with reality and the 2014 regulamentation. What kind of benefits could have toyota to use a 3.0L or however a poor torque/high rev engine? Surely will be powerfull (as you said a NA petrol engine higher revs and more hp developes) but will lack of low-mid rpm torque, ok there is the hybrid boost, but the torque release will be less than the low-mid rpm range developed by porsche engine, and most of all how could be able to rev so high respecting fuel flows?
As reported in the super GT thread, the RV8K used in SGT had a torque peak lower than 400Nm reaching the 520-530hp over 9000rpm, let's specualte that the motor used in the TS030 and rebellion lola had an optimized torque of >500Nm (I mean only by the thermal engine) with a final power reached however over 9000rpm but not less tha 550hp. Consider also that the TS040 must to consume less than TS030, so well, in my opinion because of new regulamentations is simply impossible to develope a so high power from a so high rev motor, for the simple reason that a 2014 engine can't burn anymore the amount of fuel allowable in 2013.
A larger engine can solve problems:
if at 9000rpm are required 435Nm to have 550hp
at 7500rpm are required 520Nm to achieve the same power.
An optimized larger engine revving at 7500rpm has a more competitive torque curve and consumes less than a smaller engine revving over 9000rpm. Both achieving the same power.
Don't forget that a 7 speed gearbox will be allowed, and we know that a car consumes more during acceleration, helped by the hybrid boost, toyota and porsche could use an electronic revlimiter to 6000rpm in first 4 or 5 speeds to save fuel and use the torque peak of the thermal engine + hybrid boost to have a better and more efficent AWD acceleration, using the whole rpm range of the engine only in 6th and 7th, and only where is needing: long straights.
