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.
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.
Comparison of Turbo’s and superchargers
Both work on the same principle they blow air into the engine under pressure. Both have a turbine which spins up depending on the engine speed and the higher the revs the greater the volume of air is forced into the engine. But there are some major differences between the two and which is best for your project?
