Stage 1, 2 & 3 tuning mods explained

We 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.

Clutch tuning: performance clutch modifications and triple plate clutches setup

The clutch takes the engine power, and puts this down through the drive shaft, to the driven wheels on the road but allows you to disengage the engine whilst performing a gear change.

Contact like this requires a lot of grip and a fast response. The more power you have the harder it is for the clutch to operate.

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.
