A conventionalengineproduces its power by burning thefuel. Thecombustionprocess releases the heat energy which results in the generation of expanding forces known as power. The engine’s power is commonly measured inBrake-Horse-Power(bhp),Pferdestärke(PS) which is the German translation of horsep...
Scottish Engineer James Watt invented the horsepower metric in the late 18th century to compare the output of steam engines with the power of draft horses. Watt realized that horsepower could be used to express the rate of engine power. How do you calculate horsepower? The answer is simple: h...
The basic approach to car tuning is to allow the car to burn more fuel. This requires an increase in air supply, and in some cases, the fuel systems will also need to be upgraded. The cut away engine diagram below shows the engine intake charge in blue, and the exhaust charge (red) ...
A small supercharged 1.4 engine could produce 230bhp easily whereas a 2.0 NA (naturally aspirated) engine would struggle to get above 200BHP. Most tuners accept a theoretical ceiling of 100bhp per liter on a NA (naturally aspirated) engine. With a supercharger you can push way beyond this. ...
Pete's box doesn't change the map/curve, it only fingers 'conditions seen' - the ECU simply goes by that to calculate - per revolution - the quantity of fuel to be injected. It does not 'communicate' with the ECU CPU/ROM to make a difference. It only influences indirectly by making...

Many thanks toentrypointfor our web hosting and SEO who are based inDeal, Kent. My motivation for creating this site was the misleading claims made by the manufacturers of performance parts. They often quote power gains of 30bhp and in reality this was achieved on a v8 engine in ideal lab...

Under light load a fairly standard engine should not overheat.Major mods resulting in a fair increase in BHP may require additional cooling, but only to deal with the extra heat generated when using this extra power.If you don't use it for long periods you may not need to do anything as...
Most turbos come with airflow maps that can be used to calculate the fuel requirements. We have a video that explains ECU mapping in more detail. Aftermarket ECU's - good for turbo upgrade projects It helps you to get more out of your vehicle than the OEM ECU. Stock ECUs are typically...
