Understanding Engine Power Measurement It is important that one understands that there is no written rule to measure power directly. It has a lot of dynamometers which can measure the torque and allow the power to be calculated. This is a basic equation which allows one to develop design and development work. There are two main methods to find the right power which is used in the automotive industry. Dynamometer Testing Methods The automotive industry relies heavily on precise measurement techniques to evaluate engine performance. Dynamometers serve as the primary instruments for these assessments, providing accurate torque readings that form…

Introduction This Engine Tuning Guide is intended to give a broad idea of the sort of power increases one can realistically expect to get from normal tuning modifications. Of course there will always be engines which break the rules in some area or another but in the absence of a specific tuning article on a particular engine this guide will give you an idea of what to expect. It is applicable to road and fast road engines only. Race engines are too specialised a subject for a general guide like this to be of much use. The percentage power increase…

If you already operate your own motor trade business, there is a legal requirement that indicates that you must have some form of insurance. If for some reason you don’t already have motor trader insurance, we’ve got news for you and you’re breaking the law. When you get a motor trade insurance quote, you’ll find cover that is tailored to the automobile services that you offer. This ensures that you’re protected in case you need it. With that said, cover is offered on several different levels. Third-Party Only is one of the most basic forms of cover. However, there are some restrictions which…

From the moment that goods that require delivery enter your possession to the moment they are safely placed in the hands of the recipient, they are the responsibility of the courier. This means that if the goods get damaged, lost or stolen during transit, the courier can be held liable for the replacement of the item or items. And despite calls to reduce congestion during rush hour, city traffic is getting worse. Replacing just one item can be costly and replacing multiple items can be a huge financial loss, especially for a new courier. Insuring goods is therefore highly recommended for all…

Power and torque are just twin aspects of the same maths that determines how an engine performs and anyone wanting to tune an engine ought to benefit from a better understanding of the what the figures mean. To start we need to explain some definitions. Torque Torque is a twisting force about an axis of rotation. It is measured in units of force times distance from the axis. When you tighten a bolt you exert a torque on it. If the spanner is 1 foot long and you exert a force of 10 pounds on the end of it then…

Understanding Turbo Engine Fundamentals There are some very common misconceptions out there about tuning turbo engines. In particular whether improving flow through cylinder head and induction system porting makes any difference to power or whether all you have to do is turn the boost up. The simple answer is that improving flow can be even more important on a turbo engine than a normally aspirated (N/A) one. All engines make power in proportion to the amount of air they can breathe and anything that increases air flow into the cylinders increases power. A N/A engine relies solely on the 14.7…

What Is Computer Simulation of Vehicle Performance? Engine dynos should be capable of very high accuracy in the measurement of flywheel bhp – easily within a couple of % or so. The main problem lies in the amount of care taken to ensure that the engine is tested in exactly the same state as it will be when installed in the vehicle. Often the car’s full exhaust system is not used, sometimes because of space limitations in the dyno cell. The manifold may just be plumbed into a dyno exhaust system which doesn’t sap as much power as the car’s…

When a car moves along a flat road the engine has to work to overcome two main resistances – air resistance and rolling resistance (the drag in tyres, wheel bearings etc). The top speed of the car is determined by the amount of engine power available and the size of these retarding forces. The maths to work out these equations for an actual vehicle are very simple. In order to calculate the top speed we need to work out the size of the retarding forces. Rolling Resistance Defined as the force needed to just start a car rolling on flat…
