@jakubmusil1109 I agree 500kw na out of 1.5l is absurd but 500kw out of 1.5l is not as hard as you make it out to be the bmw m12/13 used a stock block with 2 bolt main caps if i remember right(this did fail with the crank flying out in quali) just look at a b58 they get over 750kw with port injection, con rods and more ring gap. the thing with a wrc engine is that it is in a power class so limited to 300kw for example but very high torque with a flat power curve. wrc engines are not made for peak power. the more interesting claims are that of higher bsfc and bmep as well as better swirl and tumble without sacrificing ve.

@jakubmusil1109 bmw got 1000kw out of 1.5l when it was strong enough and didnt need to meet emissions the real question is can it make the power reliably without worse emissions. unless you are assuming that he is saying 500kw without boost then i agree however the bmep is more interesting and if a rotary valve can crack the 128nm per liter with petrol.
