Swap hard limits
Not a parts list. A map of what typically becomes the bottleneck as power and grip increase.
Limits are usually conditions, not universal numbers
Practical context
A component does not have one universally safe horsepower limit. Engine condition, detonation, fuel quality, torque curve, RPM, temperature, lubrication, calibration and duty cycle all change the stress it experiences. A part that survives a short dyno pull may fail during sustained track use at a lower peak number.
When evaluating a community-reported limit, ask what actually failed and under what conditions. A connecting rod bent after knock, a clutch slipped when hot, an axle broke during wheel hop and a gearbox lost a gear during a clutch kick are different failure mechanisms requiring different fixes.
Use limits as prompts for inspection and margin. If your target sits near a widely reported weak point, budget the supporting system or reduce the load rather than assuming the exact number printed on a chart separates safe from unsafe.
