Fuelling uprating the fuel pump, injectors and fuel pressure regulator

More power means that more fuel is required so we need to uprate the fuel system and we look at performance mods for your fuelling to avoid running rich or lean.

It is essential to keep the mix of air to fuel exactly right. Power is lost when the engine adjusts itself to stop it running too rich or lean. Many power losses, which manifest themselves as flat spots, at certain points in the rev band can often be traced to a fuelling issue so we will look at performance fuelling upgrades and parts.

Building a 10 second car

We look at what it takes to build a 10 second car and examine the power and weight requirements to reach the sub 11 second goal on the drag strip.

Follow our tips and you can make a 10 second car quite cheaply and within your budget with some power mods and serious weight reduction.

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.

Electric water pumps

In a performance engine you should never underestimate the need for adequate cooling.

All water cooled cars work on the principle of water being pumped around the engine and then to a radiator where it releases the heat.

Most water pumps are mechanical and run off the crank.
