How to smooth your airbox, we look at smoothing and drilling airboxes, provide a how to guide and show the benefits and drawbacks and performance gains from having a smoothed airbox.
Particulate filters and FAP Performance gains.
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).
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.
Hybrid turbos
As a rule the turbo engines are stronger than the NASP equivalents and are able to handle substantial power gains.
The key thing in a turbo engine is the flow rate that can be generated and this depends largely on the internal profiles of the impellers inside the turbo.
