So what exactly is engine knock and how dangerous is it? What causes engine knock and how can it be avoided?
You may notice a knocking or rattling noise from your engine or a sudden loss of power under full throttle.
Immediately back off the throttle and only use low rpm engine speeds until you can get the engine investigated.
The chances are that you are suffering from a condition known as “engine knock”.
Increase engine displacement with a rebore.
You can increase the power of an engine by increasing its capacity. This is a fairly involved process and requires a good deal of research and preparation. Unless you want to have to retrace your steps and go a different route midway in to the job.
Some of TorqueCars.com members have had their engines rebored ,and this does seem a good way to increase power. However there are a few things we should take into account.
Principles of porting an engine and big valve conversions
The inlet and outlet ports on the engine block are usually larger than those of the manifolds that connect to them.
This allows for scope in the manufacturing process to allow for mismatched alignment.
Generally the engine ports are larger in the upstream flow direction avoiding turbulance but power gains can be made by matching these up.
Remaps for diesel engines
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.
