Range Rover Sport Tuning

"Thanks for reading this Range Rover Sport tuning guide."

The Range Rover sport is one of the best selling cars for the Land Rover group.

There are many off road sports utility vehicles around but the big daddy, the one that can actually cope well off road is the Range Rover sport.

We'll look at mods for the Range Rover Sport to increase power, and improve the handling, the two areas we get asked about the most.

The Range Rover Sport is a good project car to play with. If you do your homework then you can create an awesome Range Rover Sport but don't be fooled there are lots of high performance upgrades out there that will simply not suit it read our unbiased guides first.

Handling/Suspension upgrades

Handling modifications are top of many to do lists for the Range Rover Sport.

We found that most Range Rover Sport factory suspension setups need tweaking, a few degrees of toe out for cornering or toe in for stability, -0.9 to 1.5, and some negative camber will greatly enhance your cornering and handling.

We would go to a maximum drop of 22mm - 38 mm on most models. You risk ruining the cars flexibility and handling on the arches if you go lower than this. Most Range Rovers sports we've seen have had higher suspension fitted, to make it a more capable off roader!

To be frank though, the Range Rover Sport is an offroad enabled car and only looks right on higher suspension. Fitting good springs and slightly firmer damping will help the cornering without compromising the look of the car.

Don't just look at the peak power figures, you need to see the whole torque curve when determining if a mod is right for you Range Rover Sport.

Enjoy your Range Rover Sport to the limit with our dependable modding guides - do the right mods in the right order.

Smaller engines do not provide much of a return in terms of power so start with a bigger engine. Engine swaps are a good option if you have a small engine size.

Engine tuning mods.

The following sports modifications are usually carried out by our members, decide how far you wish to go in your tuning project before you get going.

Getting the best modified upgrades for your planned usage of the car is vital. Stage 3 motor sport mods just won't work well on the road and will make the car undrivable.

Best Engine Mods for your car

  1. Mapping - remapping provides the most advantage in terms of cost savings,  aftermarket ECUs, and piggyback ECUs are all alternatives.
  2. Fast road cams are one of the most significant mechanical changes, but they must be installed by someone who knows what they're doing and they are not always easy to source but you might find a local firm to regrind a stock camshaft.
  3. Intake and Exhaust - Note that on their own these mods will NOT ADD POWER in most cases, but they can help enhance power after other mods by removing the restriction.
  4. Upgrades to turbochargers and superchargers - forced induction is the most efficient approach to increase air supply, allowing you to burn more fuel and make more power. It is one of the most costly upgrades but provides the best gains.
  5. Head work - The goals of porting and flowing the head are to get air flowing into the engine while removing flow restrictions and turbulence.

Typical stage 1 mods often include: Suspension upgrade (drop 22mm - 38 mm), Panel air filter, Lighter flywheel, Alloy wheels, Sports exhaust, Remap.

Typical stage 2 mods often include: fuel pump upgrades, Ported and polished head, high flow fuel injector, Fast road cam, Power/Sport clutch.

Typical stage 3 mods often include: Competition cam, Adding or upgrading forced induction (turbo/supercharger), Internal engine upgrades (pistons/head/valves), Engine balancing, Sports gearbox.

Your aim when tuning the engine should be a flat and wide torque range. You don't want all the torque to be at the top end of the rev range unless you are creating a competition car.

The point of our advice is to give a limited introduction of customizing upgrades and point you in the right direction, our forum is the place to go for detailed advice and tips on your modified car project, the best motorsport parts and all aspects of modding cars.Fast road cams offer one of the biggest torque gains for your money as far as a bolt on sports parts goes on a NA (naturally aspirated) engine.

It improves the intake and exhaust durations and increases the power if done right. Ideally you'd add other mods and finish up with a reflashed ECU. We'd also caution you not to go with a motor sports profile cam as this upsets the engines idling and general town driving characteristics.

When pushing up the power you will need to look at to the fuelling. More power needs more fuel.

If you find you get flat spots and surges after your sports mods you should check the fuelling and try a higher octane fuel as well. Higher capacity injectors will enable you to supply sufficient fuel to the engine.

Uprate the fuel pump to cope with the extra fuel requirements of your tuned Range Rover Sports uprated injectors.

Intake and Exhaust Tuning.

Now we move on to the intake and exhaust and ensure proper flow through the engine. Induction kits will only help to increase power if the cars air intake is restricted! Adding an induction kit to most stock engines will see LITTLE LOW END POWER GAIN AT ALL. If you have heavily modified your engine and it's need for air INCREASES DRAMATICALLY then an induction kit is the answer and will help remove this restriction.

Maximum power gains come from a full induction kit with a cold air feed on heavily tuned engines, this can be sited within an air box but a performance panel filter should suffice for most applications. TorqueCars suggest you use a panel air filter as these are easy to clean and maintain and generally perform better than paper ones.

Sports exhausts equal out the flow of gases through the engine. But if your exhaust is too large, ie: over 2.5 inches bore, you will lose a great deal of the flow rate and end up lacking power and torque.

Head porting and polishing the head will allow you to maximise your air/fuel charge. Leave this to a professional though with a proper flow bench and machine tools A good heavy duty fast road sports clutch will help to keep that power going where it should. Never skimp or expect a standard clutch to cope. The best mods in our experience for your Range Rover Sport are fast road camshaft, remap, induction and exhaust, suspension.

Turbo engines are just crying out to be Upgraded. You will see massive power gains on most modern turbo engined cars including diesels making a remap one of the most cost effective and massive modifications for your money.

We've also seen some tuners toying with twincharging conversions and making some very high power figures.

Despite the large cost involved adding forced induction to a NA (naturally aspirated) engine will give large power gains. Superchargers are generally easier to add than turbos. It is difficult to map fuelling with a turbo as the boost builds exponentially with engine speed.

It is easier to map a supercharger because the boost is proportional to engine speed on a linear curve. Adding forced induction will often require a lower compression ratio or water injection.

Alloy wheel upgrades.

Due to the fact that alloy wheels are less heavy they improve performance and they can help to cool the brake disks. Pay attention to your choice of tyres (tires) for your car, a good directional tread pattern tire can really enhance your cars handling. Large Range Rover Sport alloys can decrease performance. If you get big alloys you will be changing your final drive ratio.

Due to this we would advise sticking to a maximum wheel size of 19 inches, although we know some of our members have installed larger rims with no problems.
