TECH: NACA / NASA Duct

Let's take a quick detour from the Echo and have a look at on my (other) favourite cars right now, the Nissan GTR.

A cool feature of the GTR is the twin vents/scoops on the bonnet. Ever wonder what they are?

Supercharger or Turbo oh noe!

Since buying the Echo I've had my heart set on the BLITZ Supercharger.

After reading numerous forums and reviews, it turns out TRUST/GReddy also do a supercharger but they also bundle their e-Manage piggyback Engine Control Unit (ECU) with it! The BLITZ Supercharger has its own little ECU box but is not as tunable as the e-Manage so I switched my sights to the GReddy supercharger! But...

The Pursuit of Performance - Part 2

Previously, weight reduction was discussed as a method of improving an automobile's performance. So how else can we better move the weight? Improve the motor! Let's look at how (in general) a motor works.

The Pursuit of Performance - Part 1

Tuners out there are in an eternal pursuit of performance! So many elements, big and tiny, affect an automobile's capacity to accelerate faster, run further and be more efficient. So let's take a look at what affects the car's power and it's ability to use it!

Modification Harmony (Yin and Yang)

I've talked about whether or not to boost in a previous post and perhaps I might elaborate on the consequences and compensations of modifications.

A lot of people think that modifying a car from it's original design (without compensating its effects) will always better for the car. I believe this isn't the case.

Fried Rice: Sinangag

As promised, here's the first of many fried rice related articles! So, let's start with something super simple!

To Boost or not to Boost?

Ever since owning a car I've been wondering whether I should boost it or keep it Naturally Aspirated (NA). Boosting is the pressurisation of the intake (boost pressure) to force more air (forced induction) into the motor to increase the motor's power output (through combustion). NA is simply that, the natural aspiration of the motor without forced induction.

The main reason for boosting is for more power. As more air is available for combustion, the motor can create more power when the correct amonut of fuel and timing is applied.

But there are also some hinderances including but not limited to:
