Automotive Build Guides
How to plan a modified car properly: what limits power, what has to be upgraded alongside it, and the order to spend in. Written guidance, not product advertising — always confirm specifications and certification requirements for your own vehicle.
Power & airflow
- How to plan a 500hp street car buildA staged plan for a reliable 500hp street car: airflow, fuel, cooling, drivetrain and braking, and the order to buy parts in.
- Turbo sizing guide for performance buildsHow to choose turbo size using airflow, target power, engine displacement and intended use, and why compressor maps beat rules of thumb.
Fuel
- Fuel system sizing: injectors, pumps and linesWork out injector flow, pump capacity and line size for your target power, including the differences between petrol, E85 and methanol blends.
- Choosing injectors for a performance buildInjector flow, dead time, spray pattern, impedance and idle quality — what actually matters when picking injectors for a modified engine.
Cooling
- Intercooler sizing and charge coolingHow core size, frontal area, pressure drop and airflow affect intake temperatures, and how to choose an intercooler that suits your driving.
- Cooling requirements for high-horsepower buildsRadiator, oil cooling, airflow and coolant choices for performance engines, and how to tell whether heat is a capacity or an airflow problem.
Drivetrain
- Clutch selection for modified carsChoose a clutch by torque capacity, driveability, flywheel mass and intended use, and understand the trade-offs of multi-plate setups.
- Drivetrain upgrades: what breaks and in what orderGearboxes, diffs, driveshafts and axles under increased power — how to predict the next weak point and spend in a sensible order.
Chassis, brakes & suspension
- Brake requirements for high-horsepower carsWhy brake fade is a heat problem, and how pads, fluid, rotors, cooling and tyres decide stopping performance on fast road and track cars.
- Suspension setup basics for modified carsRide height, spring rate, damping, alignment and bushing choices, and the order to change them in so the car improves at each step.
