Performance Upgrades

BMS Motorsports - Performance Upgrades

1. Engine Internals

Our vast experiences over the years have given us invaluable knowledge in producing quality street and race engines. Different applications require different engine specifications and tolerances, be it drag, track or street driving.

With a team of experienced mechanics and sophisticated equipment and facilities, we area able to build reliable and lasting engines. Customers can also opt for aftermarket parts which are strengthened and forged, like Cosworth, CP Pistons, ACL, Brian Crower etc.

2. Cooling Systems

Aftermarket radiators, intercoolers and oil coolers are available in assisting the overall cooling down of your motor. The following are especially essential to regular and hardcore trackies.

4. Forced Induction / Turbo

A turbocharger is a gas compressor used for forced induction of an internal combustion engine. A form of supercharger, the turbocharger increases the density of air entering the engine to create more power. A turbocharger has the compressor powered by a turbine which is driven by the engine's own exhaust gases rather than direct mechanical drive. This allows a turbocharger to achieve a higher degree of efficiency than other types of forced induction compressors which are more vulnerable to parasitic loss.

Aftermarket turbos like Blouch, Owen, IHI, MHI and Tomei are available here at BMS Motorsports.

5. Exhausts (LTA approved)

An exhaust system is usually tubing used to guide reaction exhaust gases away from a controlled combustion inside an engine or stove. The entire system conveys burnt gases from the engine and includes one or more exhaust pipes.

To maximise the performance of your ride, we have several options of aftermarket exhaust system (Both LTA compliant and non compliant) here at BMS Motorsports.

6. Brakes

A brake is a device which inhibits motion. Its opposite component is a clutch. The rest of this article is dedicated to various types of vehicular brakes.

Most commonly brakes use friction to convert kinetic energy into heat, though other methods of energy conversion may be employed. For example regenerative braking converts much of the energy to electrical energy, which may be stored for later use. Other methods convert kinetic energy into potential energy in such stored forms as pressurized air or pressurized oil. Still other braking methods even transform kinetic energy into different forms, for example by transferring the energy to a rotating flywheel.

We have a wide range of variety of aftermarket brake kits and brakepads available for u to choose from.

7. Transmission

Aftermarket clutch systems like Carbonetics, Ogura and HKS are available. Services like the repairing of syncros are also one of our expertises.

8. Air Intakes

A cold air intake is a device used to bring lower temperature air into a car's internal-combustion engine, to increase engine power and efficiency.

Standard air intake systems tend to be very restrictive sacrificing engine power or efficiency in order to eliminate engine noise. Aftermarket cold air intake systems come in many different colors and sizes, and are easy to install when compared with other performance-increasing modifications. Because cooler air has a higher density (greater mass per unit volume), cold air intakes generally work by introducing cooler air from outside the hot engine bay

9. Suspension / Chassis / Handling

The suspension dampers on vehicles are designed to achieve two main important functions during various driving conditions. They are weight transfer and absorption. For a daily street driver, the ability for the suspension to absorb and smooth out uneven road bumps is essential in providing a comfortable ride. For pro & track drivers, the ability in acceleration and braking (longitudinal G Force) and to negotiate corners (Latitudinal G Force) relies very much on the suspension’s characteristics in the weight transfer of the car.

Aftermarket suspensions brands like APi Racing, Tein, Cusco and KW are available for our customers to choose from.

10. Electronics gadgets

A wide variety of electronic gauges and boost controllers is available.

11. ECU tuning

The Electronic Control Unit (ECU) is the “brain” of the engine. It is a computer inside a protective metal box under the carpet in the passenger foot well. Taking information from many sensors, it coordinates the fuel injectors, spark plugs and, where appropriate, turbo boost. We will discuss each of these briefly so that you have an idea what's the minimum an EM system should have.

When a car comes from the factory, its ECU is set up with very cautious settings from the manufacturer, designed to take account of a wide variation in engineering tolerances, driving conditions and environmental factors. To fine tune each engine off the production line would take more time money and resources than makes sense for the manufacturer.

Closed loop – this method uses the lambda sensor to set the air/fuel mixture to 14.7:1 which is the point for complete combustion of petrol. This gives good emissions and economy at idle and cruise. It is not useful for high power.

Open loop – this method mainly uses inputs from the mass airflow (MAF) sensor and engine speed to control the amount of fuel required at higher engine loads – typically when on boost when richer mixtures are required for power and detonation control. When the MAF reads and translate a known amount of air going into the engine a desired air:fuel ratio can be achieved. A failed MAF sensor leads to poor running, and usually a check engine light and “limp home” mode where engine speed is limited to typically 3000 RPM and boost to 8 PSI. When the MAF fails, the consequence of this is that the ECU runs too lean and too much ignition advance. This can pose a serious threat to the engine from detonation. With a working knock sensor the ECU will sense this detonation and try to control it by adding fuel and retarding the ignition timing.

Ignition Timing

This is determined mainly from the MAF sensor and the engine speed. There are maps for high octane and low octane fuels and the ECU selects between them depending on knock sensor activity. The ECU also learns ignition timing from the knock sensor and effectively sculptures these maps over time.

The Subaru ECU runs highly active timing where it relies on the knock sensor to advance or retard the time the plug sparks. On boosted engines, very often the limiting factor on maximum timing one can run is the pressure within the combustion chamber. Boost is one that raise this pressure significantly. Minimum best torque (MBT) timing is the point to aim for on all engines – practically on a turbocharged engine detonation limits ignition advance before the torque starts to drop off from advancing the timing further.

Dastek Unichip

Unichip is a state of the art piggy-back ECU (Engine Control Unit), designed to optimise the tuning of your petrol car in harmony with your existing ECU. Because every UNICHIP is live tuned to your vehicle, you can be sure you're getting the maximum out of your car and any modifications you've made to it.

Using the up-to-the-minute tuning facilities of the UNICHIP we can guarantee to give you 100% of your engine's performance 100% of the time. What's more, using our unique modular design, UNICHIP can control just about any performance modification you can think of.
