What is a billet camshaft?
Billet Camshaft is made from a semi finish solid metal form.
In theory, an engine camshaft if made from billet, it will give very good high-end performance if fitted to an engine.
With a billet camshaft, a manufacturer will be able to determine exactly when the opening and closing of the valve will be, how long the duration of the lift will be and last but not least, how much will the overlap be.
Keeping in mind the above, depending on how the billet camshaft is profiled, the performance will vary.
Google will be your best friend to read up on more details.
The product that we will be reviewing today will be non other then
Works Engineering Performance Billet Camshaft.
Why this particular brand?
Because Works Engineering has been developing products particularly for this specific car model which coincide with the car that I am driving now.
Which is a Proton Satria Neo.
They, Works Engineering, even purchased a Proton Satria Neo for their product development purposes, as seen in the pictures below.
Initial assessment of the performance camshaft by people in the automotive industry is very positive based on the specification of the camshaft itself.
How is this Works Engineering Performance Billet Camshaft different from others out there in the market?
Take some time to study the information below.
Diagram shows 61 degrees of overlap which in theory will translate to a very rev-happy engine.
Image above shows the different part of a camshaft.
Below is the information with regards to the diagram above.

Too much technical information to digest?
Me too.
But I will be glad to introduce someone to you who can explain everything clearly to you.
Anyway, from the above technical detail and description of Works Engineering Performance Billet Camshaft, everything sounds and looks good on paper right?
It has all the right specification at the right place, all chart and graph shows that it is superior in every way.
Now for the million dollar question, how will the real world performance be?
