The inlet and outlet ports on the engine block are usually larger than those of the manifolds that connect to them.
This allows for scope in the manufacturing process to allow for mismatched alignment.
Generally the engine ports are larger in the upstream flow direction avoiding turbulance but power gains can be made by matching these up.
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).
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.
Remapping the ECU – tunes or remaps benefits and issues
Back in the good old days – the task of timing the ignition spark was performed by the distributor. The greater the RPM, the more the timing would advance.
This did a reasonable job but for the most effective power you would need to vary the timing to a greater degree than a fixed ratio advance curve. The electronic ignition system was borne.
