VW T-Roc Tuning

"Thank you for reading our VW T-Roc tuning article."

The T-Roc is a good car modification project to do.

With the right mods your T-Roc can be transformed into a stunning project.

Don't waste money, do your homework and follow our unbiased guides to each performance upgrade to avoid disappointment.

Handling/Suspension upgrades

Improving the handling for loads of people first priority in your T-Roc tuning project.

We found that most T-Roc factory suspension setups need tweaking, a few degrees of toe out for cornering or toe in for stability, -0.8 to 1.3, and a tiny bit of negative camber will radically benefit your cornering and handling.

Drop the car optimally somewhere in the region of 28mm - 39 mm and fit motorsport grade stiffer dampers, bigger drops will need other modifications in most instances.

Top end bhp should be your overall aim with a nice fat wide peak torque band.

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.

Please watch our video introduction to VW Tuning.

Tuning modifications.

These are the upgrades are usually carried out by our members, decide how far you wish to go in your tuning project before you get started.

We have guides for the following VAG group engines. (More will be added soon)

Engine swaps are quite popular mods for this model, here are engine guides to all the VAG engines we've covered.

• 1.4 1.5 TFSi tuning
• 1.4 TSi/TFSi/Twincharge tuning
• 1.8T engine Tuning
• 1.8 & 2.0 TFSi (mk1) Tuning
• 1.8 2.0 TFSi (ea888) Tuning
• 2.0 TFSi carbon issue & care guide
• 2.5tfsi tuning
• 3.0 V6 24v TFSI Tuning
• 2.8 V6 30 valve, 24 valve 3.0 V6 30v and 3.2 VR6 Tuning
• 3.6 VR6 Tuning
• 1.6 TDi tuning
• 1.9 TDi tuning
• 2.0 TDI 140-170 tuning
• 2.0 TDI tuning (EA188)
• 2.5 TDI tuning
• 2.7 & 3.0 TDI tuning

Getting the right performance parts for your planned usage of the car is essential. Stage 3 (competition) mods just won't work well on the road making the car difficult to drive.

Best Engine Mods for your Car

1. Engine Tunes - engine tuning/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: Remap, Sports exhaust, Suspension upgrade (drop 30-40mm), Lighter flywheel, Panel air filter, Alloy wheels.

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

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

Your aim when modding the engine should be a flat and wide torque band. 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 whole aim of our advice is to give a starting base of customizing mods and point you in the right direction, our forum is where you can ask for more detailed advice and tips on your customized car project, the best modified modifications and all aspects of modding cars.One of the most cost effective mechanical uprated mods you can do to your NA (naturally aspirated) engine is to fit a fast road cam .

The exhaust & intake flow play a large part in your cars power band, but be careful here, getting this wrong can upset the idle and make the car hard to drive in traffic. You'd need to follow a cam upgrade with other mods and finish with a tune/remap for the best performance gains.

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

Using high octane fuel is another option if you find you are suffering from detonation or premature ignition on your VW project after fitting other tuning upgrades. Uprating the injectors is another beneficial modification and will deliver sufficient fuel.

A fuel pump will only deliver a finite amount of fuel, so you may need to uprate this if your injectors are demanding more fuel.

Intake and Exhaust Tuning.

Now we move on to the intake and exhaust and ensure proper flow through the engine. Please note that WE DO NOT FIND IMPROVEMENTS WITH INDUCTION KITS, unless you have tuned your car extensively and are finding that the standard air intake has become a restriction.

For most T-Roc engines TorqueCars would suggest you just go with a washable panel air filter. On heavily tuned engines and turbo vehicles an induction kit will help release the power providing you address the problem of supplying cold air.

Sports exhausts can help equal out the flow of gases through the engine. But if the exhaust pipe is too big, ie: it's over 2.5 inches bore, you will lose much of the exhaust flow rate and end up lacking power and torque.

Head work including a head port and polished and 3 or 5 angle valve job will really help to release the potential of the engine. In nearly all cases of T-Roc tuning your clutch will start to fail and this should be improved - read our tips on clutches for more information. The best mods in our experience for your T-Roc are remaps, sports camshafts and induction improvements.

Turbo engines are just asking to be remapped. You will see massive power gains on most modern turbo charged cars including diesels making a tune/remap one of the most cost effective and massive modifications for your money.The most impressive power gains for NA (naturally aspirated) engines usually involve the addition of forced induction. Turbos are generally harder to add than a supercharger. With a turbo the boost curve is related exponentially to the engine speed making it difficult to map fuelling with.

The nice proportional boost and rpm characteristics of the supercharger make them easier to map. Alternatively you could add water injection to reduce the risk of knock.

Alloy wheel upgrades.

The benefits of alloys include lowering your unsprung weight and more efficient brake cooling via the extra air flow they allow. Don't forget that your choice of rubber greatly affects your cars grip and handling. It is not worth compromising performance with cheap tyres when you can buy soft compound performance tires.Large T-Roc alloy wheels can decrease performance. If you get big alloy wheels you will be changing your final drive ratio.

Due to this try to keep the overall rolling diameter of the wheel the OEM setup. In all cases we do not recommend going bigger than 17 inches. (18's reportedly work fine but in our opinion they really hamper the handling and are prone to tram lining and can be quite crashy.)
