EFR6758 can hit 400, people have already done it on other platforms. Theoretically the 6258 can hit it too but would take a killer tune and very well designed parts all over the engine bay.
That 8375 is insane, you make the same torque as I do at my peak torque rpm, with a freaking td04, although I hit 300ftlbs sooner. Like holy ****.
