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 tune a car engine for power or economy
Let’s take a look at ways to tune a car engine and what exactly we mean by engine tuning.
First up we have to accept that there are many different types of engines.
We can only cover generic theory in this article on how to tune a car and suggest if you want more specific advice you sign up to our car forums where our helpful and friendly members will assist you further.
Benefits and drawbacks of engine water injection systems
You’ve finished tuning up your engine but you find that at full throttle the engine splutters or stalls. When you get the car on a diagnostic you find that the knock sensor is kicking in to protect the engine.
Engine knock is a condition where the fuel inside the engine ignites prematurely and occurs within an engine running at high compression. (It can also be caused by other factors including low octane/poor quality fuel or hot spots within the engine.)
Particulate filters and FAP Performance gains.
The particulate filter is a stand alone unit. It is located upstream of the cat in the exhaust system and its purpose is to remove soot particles from the gas stream. The cat the proceeds to do its usual job of converting CO to CO2 and is in no way dependent or relied upon by the particulate filter.
In diesels the cats are two way devices and run in unregulated mode (ie. no O2 sensor like a petrol car).
