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). Read More...

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. Read More...
Giggle gas – something to put a smile on your face.
"Giggle Gas – Nitrous Oxide (N20) the power button!"
NB: NoS is a brand name of a company but many confuse this with the name of the gas Dinitrous Monoxide AKA – Nitrous Oxide N20, Dinitrous Monoxide, Dinitrogen oxide also referred to as Nitrous or giggle gas (from its medical usage as an anaesthetic.
It was used in wartime to boost the engines in aircraft and later became a big hit in drag racing in the Pro Mod class. Not a flammable gas in itself it is injected into the intake manifold where it mixes with air & fuel. The main benefit of Nitrous comes as it burns and becomes an oxidiser releasing more oxygen into the engine.… Read More...

Tuning turbo engines.
"A lot of hot air."
What is a turbo. If you go back to your childhood you probably remember those windmills sold at the seaside. Imagine a windmill with 2 propellers back to back.
As the wind blows the first propeller a shaft turns the second one and it will blow air in your direction.
A turbo contains 2 impellers which are located in the exhaust flow and along the intake path. The exhaust side rotates as the exhaust gases flow and this turns the impeller on the intake effectively sucking in fresh air.… Read More...
