Youll be fine. Just dont racecar ur racecar while ur running 87

Doesn't really work that way. You are most at risk from peak cylinder pressure. This is in the midrange at peak torque. So you can innocently hit the happy pedal while at 3K on the HWY or in town to pass someone and there you go with a 4000 RPM pull. You won't likely be able to hear any knock.

Yes, there is knock detection in just about every modern car which helps to shift the timing map entirely upon detection but why rely on that if you don't have to
