- 006: How does an ignition coil work?
**This is a replay from the old podcast series lost to the internet**
Original upload date: 15/04/2020
This episode is a quick discussion about how does an ignition coil work. All ignition coils work the same way using the process of electromagnetic inductance.
Ignitions coils are constructed using an iron core. This iron core is wrapped in thin wire called the secondary winding. The secondary winding is wrapped in a thicker wire called the primary winding and is normally with a lot less windings than the secondary winding.
Current and voltage is applied to the primary winding which produces a magnetic field. When a spark is required the supply to the primary winding is cut and the magnetic field collapses.
As the field collapses the magnetic flux line through the secondary winding creates a higher voltage (due to the increased windings). This higher voltage is directed to the plug and creates a spark.

5 min - 005: Spark plug heat range explained
**This is a replay from the old podcast series lost to the internet**
Original upload date: 16/06/2020
What to know what spark plug heat range is and how it affects your engine performance? A spark plug heat range is a measure of the spark plug thermal performance to transfer heat from the combustion chamber into the head.
If the spark plug does not conduct enough heat (a cold plug to NGK scale) it will remain cooler causing carbon fouling. If a spark plug conducts too much heat (hot plug on NGK scale) the plug can overheat causing damage to the plug as well as your engine.

5 min - 004: Do you use factory or manufacturer tolerances?
**This is a replay from the old podcast series lost to the internet**
Original upload date: 28/04/2020
Today's podcast episode is thanks to a question I received from David Moynihan. David hit me up on Facebook messenger about his unique stroker build and was which piston ring gap should be used, factory or the manufacturer's specification.

6 min - 003: Unequal, equal and tuned length exhaust manifolds
**This is a replay from the old podcast series lost to the internet**
Original upload date: 15/04/2020Do you want to understand the three main kinds of exhaust manifolds? Exhaust
manifolds can be grouped in unequal, equal and tuned length manifolds. Thereare a few key differences explained in this podcast.Links

12 min - 002: What is investment casting?
**This is a replay from the old podcast lost to the internet**
Original release date: 06/04/2020.
What is investment casting? In this episode I discuss what it is and how it is used by Whitley Tune to produce high end bespoke car parts particularly intake manifolds.
The traditional method of investment casting uses a die mould that is injected with wax. That wax profile is then dipped in a ceramic slurry and dusted with stucco to build a ceramic shell. The shell is built up a number of times until the shell has sufficient integrity to hold the molten metal.Whitely Tune uses a different method where by a sprue of the part is prepared in CAD and 3D printed using a bioplastic PLA. The sprue is suspended and cast into plaster. The sprue is then removed in a furnace leaving a mould ready for casting.Links:

I thought I’d start with a discussion about ignition
timing and what is the underlying principle for why ignition timing changes.Links

Do you want to expand your automotive knowledge with something a little more technical but don’t want to need a degree to understand?
I’m Aaron, located in Australia and love old JDM cars. I’m not qualified in the automotive industry but I have modified cars for over 20 years starting when internet forums were new and you had to figure out solutions by yourself. I’ve picked up a thing or two along the way and I share these things in this podcast (along with the occasional JDM car culture discussion).
