V8 Supercars use a hp limit rule without issue, all engine packages are homologated on the organiser's dyno and must comply with given maximum cumulative power over the useful rpm range. Engine components cannot be changed from the homologated parts, without redynoing and rehomologating.
This rule allows for 4-5 different engine suppliers in the field, but all with interchangable performance. When engine performance was unrestricted, they would use lightweight pistons which developed cracks after one to two race meetings... That is just a waste of money wouldn't you say?
Meanwhile, the homologated engines with minimum weights for pistons & conrods can run easily for 5500km and rarely see engine failures.
Actually limiting the power is a really good idea in my opinion (I also had it). It would shift development towards more efficient PUs (and lighter ones without a weight lower limit)
It seems exceedingly silly to me to regulate screws and bores and almost every measure of an engine to get to some power goal, instead of just setting a power cap. They could just open up almost everything (cost permitting) with a power cap, starting with fuel flow limits, so we could have a variety of engines.

What problem is this solving?
Most things engine related.
