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.

High performance engine tuning mods that improve performance.

Careful selection of your internal engine tuning modifications can lift your engine from a purring kitten into a roaring lion!

While it is tempting to throw in every modification you can, it’s worth noting that not all mods work well together. This is something we cover in our articles as we steer you to the right decision on mods for your car.

The more power you want from a turbo the greater the amount of heat it will generate and the bigger the stress on the internal components.

How to add a turbo to a non turbo car.

The basic reason for forced induction (turbo or supercharger) is not to increase compression or the maximum pressure in an engine cylinder, it is to increase volumetric efficiency (the efficiency of the engine at drawing in air) although forced induction is the most effective method of upping compression.

In computer games we just tick a box, and within seconds our car is fully turbocharged and running much faster. In the real world things are very different.
