Speed limiter


HeadlinesQuick

Recommended Posts

Unless equipped with a manual gearbox, it is not possible to exceed the maximum revolutions per minute (RPM) of the engine. This is due to the gearbox's electronic control unit (ECU), which automatically shifts gears at the engine's maximum RPM. The only circumstance in which it would be possible to exceed the maximum engine speed while in the highest gear, with the torque converter clutch engaged, is while travelling in a steep downward direction. Exceeding the engine's maximum revolutions per minute would be of little concern to you at that point.

Its only function is to interrupt the ignition system when the engine reaches the predetermined maximum rotational speed. Designed to produce flames from the exhaust (for what purpose?), and is incompatible with a conventional V8 exhaust system!

During my apprenticeship, we manually performed such task on BT Morris 1000 vehicles. Deactivate the ignition while descending and reactivate it at the bottom to generate a significant explosion. The exhaust system was forcefully detached.

If one chooses to exhibit childish behaviour and the vehicle in question does not belong to them, then this may be seen acceptable. However, as pwood has astutely mentioned, this behaviour will have detrimental effects on the catalytic converters of a P38 vehicle.

To the best of my knowledge, on the Classic model, the rev limitation is integrated into the ignition system. This prevents the engine from being excessively revved if the throttle is fully opened while the vehicle is not in gear. In essence, the rev limiter functions as intended by limiting the engine's revolutions per minute.

Additionally, it is important to modify the exhaust system to a "straight through" configuration and eliminate the catalytic converters. There will be a high level of noise at all engine speeds.
