Audi RS7 Tuning

"Thanks for reading this Audi RS7 tuning tips."

The RS7 is a great tuning project to play with. The key to RS7 tuning is doing it right - a lot of money can be wasted if you do it wrong.

This actually feels fun to drive, you could easily forget you are in a practical(ish) family coupe, and think you are in something much sportier.

Audi have done a great tune tuning and fettling the A7 chassic and have created what I feel is the Ultimate Audi.

We detail the best approach to RS7 tuning and point out the optimum modifications. Audi RS7s make awesome project cars and with the optimum performance upgrades you can positively enhance your driving fun.

Handling/Suspension upgrades

Many RS7 owners uprate the handling of their cars with tuning suspension modifications as a priority, this will certainly increase your enjoyment of the car.

We feel that the RS7 suspension is a little harsh, but this could be due to the massive wheels fitted.

Good suspension tweaks that radically improve handling for the RS7 include a couple of degrees negative camber and 1-1.5 degrees of toe in or out on the front wheels. Toe in for stability, or Toe out to improve cornering. It would also pay to improve the brakes, by adding larger discs and or higher friction pads. but this may compromise straight line stability.

We would go to a maximum drop of 23mm - 39 mm. on most models. You risk rubbing on the arches if you go lower than this.

Top end power should be your overall aim on the RS7 with a nice fat peak torque band.

Keep the car looking standard and remove the badges to make an awesome sleeper!

To be completely frank and honest, on the more modest 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.

Getting the best performance upgrades for your planned usage of the car is essential. Stage 3 motor sport parts just don't work well on the road making the car difficult to drive.

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 23mm - 39 mm.), Alloy wheels, Panel air filter, Sports exhaust, Lighter flywheel, 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: Engine balancing, Adding or upgrading forced induction (turbo/supercharger), Internal engine upgrades (pistons/head/valves), Competition cam, Sports gearbox.

Your aim when modding the engine should be a wide torque band. You don't want all the power to be at the top end of the rev range unless you are creating a motor sport car.

The point of our articles is to give a brief overview of modding 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 sport parts and all aspects of modding cars.A fast road camshaft will be one of the best NASP power mods you can do with a single part fitted to your engine.

It maximises the intake and exhaust durations and pushes up the power if done right. Ideally you'd add other mods and finish up with a remap.

We'd also caution you not to go with a motor sports profile cam as this affects the engines idling and general town driving characteristics.

Don't forget to ramp up the fuelling when you are increasing the power - it makes the car more thirsty.

If you find you have flat spots and power surges after your tuning modifications you should check the fuelling and try a higher octane fuel as well. Larger injectors will enable you to supply sufficient fuel to the engine.

If you are increasing your fuelling with bigger injectors you will also need to get a bigger fuel pump to supply it.

Intake and Exhaust Tuning.

The next area for modification is the intake and exhaust. Please note that WE DO NOT RECOMMEND INDUCTION KITS, unless you have tuned your car a lot and are finding that the standard air intake has become the bottleneck.

Derestricting the air flow into the engine is the primary part of car tuners 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 sporty but due to the warm air in the engine bay they will not really increase power and more often than not rob you of power on most cars.

Sports exhausts can usually air flow from the engine but do not go too big or you might just stuff your flow rate and make things worse. So generally speaking, keep to a size of 1.5 to around 2.5 inches to maximise flow rates, and this should take into account the amount of air your engine is moving.

Getting the cylinder head ported and polished will further help more air into each cylinder. This is definitely a job for a professional with a flow bench.

Your clutch can lose you loads of power as you increase the power if it starts to fail and the standard clutches are only ever good for power gains of up to 30%.

Fit an uprated clutch to avoid power leak through the transmission. The best mods that we recommend for your RS7 are fast road camshaft, remap, induction and exhaust, suspension.

NA (naturally aspirated) engines do not achieve big power gains if you remap them, unless you have done extensive modifications. With turbocharged engines this is another story.

A remapped turbo will give big power gains and take full advantage of the strength of the block. The most phenomenal power gains for NA (naturally aspirated) engines usually involve the addition of forced induction. Superchargers are often easier to add than a turbo. It is harder to map a turbo as the boost comes on exponentially with revs.

Superchargers however will give a boost which is proportional to engine speed so is easier to map. Adding forced induction will often require a lower compression ratio or water injection.

Alloy wheel upgrades.

Alloy wheels will help the brakes cool down and are usually lighter than steel ones. We can't go into too much detail here about tires but they are how the car puts the power down on the road so are a critical choice.

Directional tread pattern tires work well on RS7s, and make a big difference over budget tires. Large RS7 alloy wheels can decrease performance. If you get big alloy wheels you will be changing your final drive ratio.

Because of this try to keep the overall rolling diameter of the wheel the standard factory sizes. In all cases avoid going above 19 inches and I'd personally stick with 18's for a daily driver as I prefer the handling and ride quality.
