Principles of porting an engine and big valve conversions
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.
Gearbox RemappingWe look at ways to improve gearchanges on your automatic gearbox. Remapping the gearbox will improve shift times, improve acceleration and provide a more lively drive. So OBD port engine tuning/remapping of modern gearboxes is possible and certainly a mod you should consider.
Lightening the flywheelLightening the flywheel – the flywheel works in a similar way to the wheel in the toy cars you used to rev up and release and let it zoom off. The heavy wheel located between the engine and the gearbox builds up rotational force with speed and momentum.
Effectively storing the energy and helping the car resist changes in engine speed – good for cruising at a steady speed but bad when you need a fast engine response.
Stage 1, 2 & 3 tuning mods explainedWe hate to shatter the illusion but they are fairly meaningless terms if applied to power gains and cannot reliably be used to explain how much power a modification adds. There is no consistant difference in part makers between their classifications of stage 1 stage 2 and stage 3 mods.
Some tuning companies will just box their parts in packs labelled stage 1,2 and 3 and maybe even 4 or 5. Such labeling is as helpful as a product number and should not be taken as any sort of guarantee of the power gains or suitability for your car.
