Double overhead cams have separate profiles for inlet and outlet ports and are more tunable than single overhead cams.… Read More...
Our members frequently talk about their latest mods and power figures. Many of our members have remapped their diesel engines and boast of more power, better economy and unchanged reliability.
But do the claims live up to reality? What sort of power figures can you get from a diesel remap? Diesels have really come so far in a very short time. Read More...
