I drive a vito 111cdi it is a company vehicle and it is restricted to 70mph as most of my driving on motorways it pain when I have to go a long distance, does anyone know how I could gain another 10 or 15 mph.
if you want speed drive a petrol van they have a wide range of RPM scope. this will allow you to use a great range of revs.
Most diesel motors have a RPM range up to and not exceeding 4500 RPM.The reason they do this is because diesel are a slow moving motor designed for high torque ranges, heavy loads are easily towed at low ranges as speed increases you drop torque and vise versa. Most diesel have limiters on them, to protect the motor from damage.
advantages protects motors,longer service life, less service calls, restricted speed , better fuel saving. changes driving habits etc
to remove the limiters you need to go to the delear and have it removed.
Or put a plug and play device in it to increase power. when you get rid of the van you take it out and motor resets its self to original settings
