4x4 Performance Packages

Exhaust upgrades

Exhaust systems directly affect a 4WD engine’s performance, and an exhaust upgrade is a simple way to improve power and fuel efficiency. Unfortunately, a factory 4WD exhaust system can often be restrictive with narrow piping and sharp bends. The simplistic and prohibitive product influences the rate gasses can escape the engine, meaning slower fuel combustion. An aftermarket exhaust allows your engine to breathe freely. The difference of quality is often easy to see, with larger pipe diameters, nicely curved bends and quality construction. A Newman Mechanical exhaust upgrade will allow exhaust gases to leave the engine quicker, allowing greater oxygen intake to improve power, torque and fuel efficiency immediately. Not to mention the impressive hum that comes with an aftermarket exhaust.

Tuning

Tuning can measure the power performance and the Air Fuel Ratio (AFR) of a 4x4 to assess its current performance capabilities. With that information, the 4x4 can be tuned to suit its needs. Thus, a 4x4 can be optimised to best suit the needs of the owner. Ideally, a balanced tuning will allow greater flexibility and not negatively affect power or fuel efficiency to satisfy the other. However, if a 4x4 purpose is primarily to tow heavy loads and navigate slippery, sandy or steep terrain, then Newman Mechanics can tune the 4x4 to prioritise maximum power output. In contrast, a 4x4 that is expected to accumulate countless highway kilometres and travel city streets would be best suited for fuel-efficient tuning.

Snorkels

Cool, clean and dense air intake is imperative for optimum 4WD performance. Engines love cool air to keep engine temperatures down, clean air to prevent particles from entering the engine, and dense air to provide more oxygen to complement the combustion process. Cool, clean and dense air will essentially allow a 4WD engine to run more efficiently and healthier. Commonly air intakes are positioned counter-intuitively on bonnets or at ineffective heights, both not ideal for off-road 4WD purposes. Installing a snorkel will ensure cool, clear and dense air intake to reduce the risk of water, dirt, sand, mud and dust from entering the engine and improving engine performance. Newman Mechanical will size a snorkel to suit your vehicle, allowing you to take on any off-road adventure you desire.

Turbo upgrades

Factory 4WD turbos tend to do the job; although, the job’s it can do are limited. In addition, 4WD manufacturers will often choose a turbo on a cost vs sales mentality, which can often mean a stock turbo is not necessarily the most efficient for the 4WD make or model. So why not upgrade your turbo to unleash your 4WD capabilities? The correct aftermarket turbo system will increase engine power and torque immediately, meaning it will boost your 4WD performance. However, it is highly recommended that all turbo upgrades are done professionally by qualified mechanics to avoid catastrophic outcomes. Newman Mechanical can perform the optimum turbo upgrade for your 4x4 to ensure you can get the most out of your driving time on and off the road. Once a turbo upgrade is complete, we strongly recommend one of our professional tunings, with significant power and torque increases guaranteed.

Clutch upgrades

A clutch is a critical component to engage and disengage the engine to the gearbox. It is more significant in a 4WD when navigating steep inclines and declines, maneuvering rugged terrain, pushing through sandy surfaces and crossing slippery river rocks. A factory clutch is simply adequate for the everyday 4x4 owner for the day to day commute, the occasion of off-road challenge and towing a trailer to the dump. It is not for the true off-road enthusiast. Newman Mechanical can upgrade your clutch to avoid slipping, squealing and the inevitable failure that will come with a factory clutch. It will complement your engine’s improved power and torque and the larger loads and unpredictable terrain you intend to drive.
