515hp could be the output release of gte cars like corvette, 488, ford gt and bmw. It's all about bop.
To me GT3 cars develope a gtlm comparable amount of downforce given by the size of splitter, wings and diffuser. Surely gt3 cars produce more drags pheraps.
Final power doesn't mean anything.... it's about the kind of engine.
take a bentley; bop can reduce the high end rpm turbo boost; it means that power @7000rpm may decreases from 530hp to 510hp at example. But the huge torque curve at low-mid rpm remains untouched!
the car will keep on having the same cutting edge acceleration, just will have a worse top speed.
While a car like lamborghini huracan has a low torque/high rev power NA engine. If you decrease restrictor size, the engine will develope less power at highest rpm, because engine will develope less torque at that rpm range. Considering that engine has a torque peak of about 520-530Nm at a medium-high rev (6000rpm). If you decrease restrictors size of a high rev engine, very likely you're wasting partially acceleration too.
That's why dyno engines suit better. Watch cadillac dpi.... they gave extra ballast, gave mandatory longer ratio at lowest speeds, mandatory settings for rear wing and got shorter restrictors size race by race.... car kept on ruling because bop can't kill low-mid rpm torque developed by the monster 6.2.
