@JORDIRX8 Exactly. If a stock car revs as high as a fully built one, there's something wrong...
Also, i didn't talk about Valvetrain upgrades because Rotaries don't have Valves/Cams and those were the most noticeable back in Payback. But at the same time, engines that aren't capable of higher rpm's stock, should be revving higher when built, it's just logic really.
