Getting the power from the engine to the wheels is the job of the transmission and this is an area where a lot of cars can lose power.
We look at the best Transmission mods from low ratio gearboxes, quick shift kits and slip differentials.
We look at converting a front wheel drive car to rear wheel drive. Problems and shortcuts and suggestions for a FWD to RWD conversion project guide. For this reason, most high power cars and motorsport cars have a rear wheel drive setup. Even front engined street cars are converted with a mid mounted engine and rear wheel drive.
Cars are more fun to drive when the power is to the back wheels. It makes for lots of oversteer rather than the safer and more predictable understeer manufacturers build into FWD cars.

We look at the benefits and disadvantages of solid flywheel conversions from a DMF and help you decide which is right for you.
It is our considered opinion that unless a car is used extensively for competition or off road you should stick with a DMF. The additional torque caused by tuning an engine or heavy competition use can quickly destroy a DMF. The solution would be to fit a stronger, higher performance DMF but the aftermarket industry seems geared up to offer solid ones as the upgrade option.

The clutch takes the engine power, and puts this down through the drive shaft, to the driven wheels on the road but allows you to disengage the engine whilst performing a gear change.
Contact like this requires a lot of grip and a fast response. The more power you have the harder it is for the clutch to operate.

Gearbox – Lower ratios give better acceleration times and lower fuel economy. Six or seven speed boxes are better matched to modern engines.
Most street applications are closer 1st and 2nd gear ratios for that off the line 0-60 boost or for the fast exec a lower 2nd and 3rd ratio give improved overtaking flexibility and 30 – 70 mph acceleration with a high 4th and 5th gear to give motorway fuel economy.

The array of available automotive engines continues to grow, we shall look at the main types of engines looking at how they have evolved over time.The gradual evolution of the automotive engine marches on and we discuss the major developments and innovations in engine technology and fuel types such as Petrol, diesel, LPG hydrogen and electric power.
The main areas for engine balancing. "A balanced article." We all know what happens when a wheel is fitted to […]
Lets look at the job of the coil in the spark system and see what it does.
Just as a power transformer converts mains 240 volts into a usable 9 volts for your charger or appliance a coil will increase the voltage.
A car battery/alternator will produce a paltry 12volts, certainly not enough to jump an air gap and create a spark.
An ignition coil raises the voltage in some installations between 20 and up to 40,000 volts and this allows the creation of a spark which can jump the air gap between the plugs.
