From a diesel perspective, anything that isn’t turbocharged is a waste of time from a tuning point of view. Similarly, anything that isn’t using electronically managed direct injection is a pointless tuning proposal so we are somewhat limited to modern Turbo Diesels.

What is brake fade and what causes brake fade?
This phenomenon known as brake fade can be quite unexpected and lethal and I would hazard a guess that 1 in 4 cars are likely to experience brake fade to some degree. Brake fade manifests itself by a spongy feel on the pedal and little or no braking force. Do not confuse brake fade with bad brakes or a mechanical fault as it applies to brake systems in relatively good condition.
Electric water pumps
In a performance engine you should never underestimate the need for adequate cooling.
All water cooled cars work on the principle of water being pumped around the engine and then to a radiator where it releases the heat.
Most water pumps are mechanical and run off the crank.
How to avoid engine knock and pinging
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”.
