No, shifting at the redline is not safe in a stock 1995 Honda Prelude Si. The redline on a car's tachometer indicates the maximum safe engine speed. Regularly revving the engine to the redline is putting excessive mechanical strain on the engine and can cause premature wear and tear, leading to costly repairs. Additionally, excessive redlining can lead to engine knocking, detonation, and even catastrophic engine failure.
When shifting gears, it's generally best to shift before reaching the redline to ensure the engine's longevity and reliability. Consult the owner's manual for the recommended shift points for your specific vehicle.
