What happens if you redline an engine

When you bounce off the rev limiter during acceleration, the load on the motor in that case is within the stress limits of the motor and reasonably proportional to the rpm speed. It only just looks and sounds bad, and costs a fraction of a second at the finish line. Redlines are set with a buffer so that in any normal range of operation, the motor is within its stress limits.

Italian tune-ups also work! The goal is to get the motor close to max operating temperature and keep it there for a little bit. I do this by hitting the freeway in second gear for a couple exits.

This is the limit that the manufacturer has tested and found to be perfectly fine in regular operation.

Running an engine up to that point will in no way damage it. In fact, all modern cars incorporate a fuel cut-off that will stop an engine from spinning past the point where it could cause damage, typically just past the indicated redline itself.

Each and every engine has something called a power curve, which describes the relationship between engine speed and the production of horsepower and torque.
