Audi Q7 Tuning

"Thanks for reading my Q7 tuning guide."

The Q7 is the large fun SUV from Audi, that still manages to tick the fun to drive box, whilst retaining it's practicality.

If you've got a big heavy car that you want to move quickly your only option is to fit a large powerful engine, and thankfully that is exactly what Audi have done.

Engine tuning mods.

All engines respond well to mapping and performance upgrades. We wouldn't want to spoil the Q7 with the wrong mods so lets take a look at the best mods for the Q7.

The Q7 is a good tuning project to play with. Think carefully and research Q7 tuning to save yourself making the usual expensive errors we typically .

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

With our pointers your Q7 can be transformed into a track car and maintain it's reputation reliable daily run around.

Sadly with smaller engine sizes you are wasting your time spending money on modifications, so if this applies to you get yourself an engine swap then apply the following mods.

These mods uprated modifications are usually carried out by our members, decide how far you wish to go in your tuning project before you begin.

Getting the right motorsport parts for your planned usage of the car is a time and money saver. Stage 3 competition upgrades just don't work well on the road making the car difficult to drive.

Stage 1 mods: Panel air filter, Suspension upgrade (drop 30-40mm), Alloy wheels, Remap, Sports exhaust, Lighter flywheel.

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

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

Your aims when tuning should be a flat and wide torque output. You don't want all the torque to be at the top end unless you are creating a motor sport car.

The whole point of our guides is to give a brief overview of modifying modifications 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 modified parts and all aspects of modding cars.One of the best mechanical upgrades you can do on your NASP engine is to fit a fast road camshaft .

The exhaust and 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 difficult to drive in traffic. You'd need to follow a camshaft upgrade with other mods and finish with a reflashed ECU to fully release the power gain.

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

If you find you suffer from flat spots and surges after your performance modifications you should check the fuelling and try a higher octane fuel as well. Upgrading the injectors is another beneficial modification and will deliver sufficient fuel.

If you've uprated your fuelling with bigger injectors you will also need to get a bigger fuel pump to supply it.

Intake and Exhaust Tuning.

Breathing mods are usually next up. Induction kits will only help to boost power if your air intake is struggling! Adding an induction kit to most stock engines will see NO 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.

Derestricting the airflow into the engine is a primary goal of tuning so get a better flowing air filter if you find that the car is running lean only if you find the car is running lean. Induction kits can sound great but due to the warm air in the engine bay they will not add noticeable power and often rob you of power.

Do not go with the largest exhaust you can get this will slow the exhaust rate - the best exhausts for power gains are usually between 1.5 to 2.5 inches. It is the shape and material more than the bore size.

Head work including a gas flow and 3 or 5 angle valve job will really help to release the potential of the engine. In nearly all cases of Q7 tuning your clutch will start to slip and this needs to be uprated - read our article on clutches for more information. The best mods we would do for your Q7 are fast road camshaft, remap, induction and exhaust, suspension.

Remaps offer phenomenal power gains on all turbo charged cars. On NASP engines the benefits are doubtful. However a remap on a NASP engine will help unleash the potential if you have done a lot of mods.

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

The most phenomenal power gains for NASP engines usually involve the addition of forced induction. Turbos are usually harder to add than a supercharger. With a turbo the power curve is related exponentially to the engine speed making it harder to map.

Superchargers will give a boost which is directly proportional to engine speed so is easier to map. To cope with forced induction you will usually need to decrease the engines compression ratio .

Handling/Suspension upgrades

Many Q7 owners uprate the handling of their cars with sports suspension mods as a priority, this will certainly increase your enjoyment of the car.

Good suspension tweaks that usually improve handling for the Q7 include a couple of degrees negative camber and 1-1.5 degrees of toe out on the front wheels.

We suggest that you fit modified suspension and lower the car by 22mm - 40 mm. Larger drops require arch work - especially on models already equipped with motorsport suspension.

Alloy wheel upgrades.

The benefits of alloys include reducing your unsprung weight and more efficient brake cooling.

Pay attention to your choice of tyres (tyres) for your car, a good directional tread pattern tyre can really enhance your cars handling. Large Q7 alloys can decrease performance. If you get big alloys you will be changing your final drive ratio.

Because of this aim to keep the overall rolling diameter of the wheel your OEM settings. In all cases without going bigger than 19 inches - yes we know the lads like running on 21's but it really wrecks the ride and handling in our opinion.There is a more updated version of this Audi Q7 Tuning article on TorqueCars.com.
