Blow off valves, dump valves and screamer pipes

Blow off valves and dump valves.
When the throttle is closed (when you lift off the accelerator) in a turbo driven engine there is a build up of pressure as forced air is still coming from the turbo. Lifting off the throttle is a lot like putting a plug in the sink – the flow through is stopped and water would just build up and overflow the sink.

Sports ignition coils and performance coil packs

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.

What is a turbo and how does it work

Tuning turbo engines. "A lot of hot air." What is a turbo and how does it work?  If you go back to your childhood you probably remember those windmills sold at the seaside. Now imagine a windmill with 2 propellers back to back. As the wind blows the first propeller a shaft turns the second […]

Alloy wheels and their impact on handling and performance.

Some rally style alloy wheels are lighter – (less weight = more speed) and also are designed to increase the cooling of the brake disks.

Some designs hold up better to being curbed than others and some break very easily when hitting a pothole or curb at speed.

Always go for the best quality alloy wheel that you can afford and read the reports and reviews. If you do go for a different overall size you must get the suspension and tracking realigned to avoid uneven wear under acceleration.

Boost controllers and remaps

Boost controllers
The turbo is driven by the exhaust gases and the faster the exhaust flows the quicker the turbo spins and more air gets forced in to the engine.

If too much air is forced into the engine then it will run lean. This causes an intermittent loss of power and you also risk putting too much pressure on the engine with a surge of power.
