Why is turbo lag a thing?
A turbo is a impeller that is spun via exhaust gas. It then spins an impeller that sucks in air, pressurises it and forces it into your engine. So your turbo takes something that you weren’t using anyway and turns it into more horsepower. Add in the fact that it often makes your car more
What is a egr valve and how does it work?
An EGR valve sounds like it belongs in your heart. It doesn’t involve ventricles or aortas, it involves exhaust gas, the intake manifold, air and fuel, and emissions. EGR stands for Exhaust Gas Recirculation, it is a valve that car makers turned to in the fight against emissions and for fuel economy. It sounds really
What is a sway bar and how does it work?
When you hear sway bar, you assume it has something to do with swaying. You’d be on the money. Also known as an ‘anti-roll bar’, it helps to distribute weight transfer and reduce body roll during cornering. It is a fairly simple idea but the engineering boffins make it an excellent one. A sway bar
What is a mass airflow sensor and how does a maf work?
To keep your engine running you need air to combine with your fuel, at the set air fuel ratio. This mixture is what gives your engine the potential energy to combust. What amount of air and what amount of fuel though? Well you have a fuel injection map to scale up and down depending on
What is a muffler and what does a muffler do?
Your internal combustion engine does many interesting things. Most noticeably, it powers your car. To do this it needs fuel and air.

What’s a crankshaft and how does it work?
Your car’s wheels spin around, the pistons go up and down. So the question is how you take the lateral movement of your pistons and turn it horizontal to make it rotational energy? The answer is your crankshaft. It takes all the energy from the pistons and sends it to the transmission. This is super
What’s a camshaft and how does it work?
Your car idles at about 750-900 revolutions per minute, rpm, this requires the valves to open and close 750-900 times a minute. Without the camshaft you wouldn’t have a working engine. It is what allows air into, and exhaust out of, the engine via the intake and exhaust valves. What is a camshaft? What a
What are radiators and what do they do?
Your car’s engine gets really hot. Mainly due to the thousands of explosions per minute. To cool the engine your car uses coolant, to cool the coolant, you have a radiator. Modern cars use newer and more high performance radiators for coolant to pass through the cooling system. So whether you’ve got an aluminium radiator,
How do brake pads work?
Your car has brakes. The size of the brakes determine stopping power, the ventilation deters brake fade, and your brake components range far and wide. There’s a lot going on with stopping your car basically. Your brake pads are what make contact with your brake rotors. This contact creates friction, which creates heat. The friction
What is abs and why do I need it?
