Arse dyno’s, unless very finely calibrated, (lets put it this way, I work with a lot of racers, I trust one of them to give me accurate arse dyno feedback. One) feel the change in acceleration, acceleration squared, effectively. Which is why engines with a broad spread of torque (S2000, RX8), get blasted by idiots on the internet for being torqueless. Because they can’t feel a constant surge, they’re waiting for a kick that never comes.
To the extent that Honda actually deliberately put a dip in the torque with the S2000 so that when it kicked back in again you got to go VTEC YO!
Engines with inconsistant torque curves that suddenly jump up and drop off (big turbo’s, etc), feel fast because the rapid change in the acceleration of the acceleration. Even if they’re not.
I can make your car feel a lot faster with the engine mapping even when it’s actually going slower by putting ramps in the torque curve - a fact many flight-by-night chipping/remap firms exploit.
