Improving air intake on the 3.0 V6 24v TFSI

You need fuel and air for an engine to work. If there is little supply of fuel then it will run lean, if there is a lack of air it runs rich resulting in lost power and potentially damaging the engine. We'll pick up on fuelling later in this article but for now we shall look at air supply.

So Forcing fuel and air into the 3.0 V6 24v TFSI engine is the aim to any car tuning project.

It is common that there is a limit in the air flow sensor (AFM/MAF/MAP) on the 3.0 V6 24v TFSI when loads more air is being pulled into the engine.

We note 4 bar air sensors coping with quite large power gains, whereas the OEM air sensor limited torque at a much lower level.

Intake carry the air from the filter and allow it to be drawn into the engine and mixed with fuel.

The size of bore and shape and rate of flow of the Air Intake manifolds can make a big improvement to fuel mixing and power on the 3.0 V6 24v TFSI.

We often see intake are crying out for motorsport parts, although some OEM provide reasonably well designed intake.

Increasing the 3.0 V6 24v TFSI valve size, getting port work and head flowing will also improve bhp and torque, the fantastic side effect is it will afford you a better bhp and torque increase on other upgrades.

3.0 V6 24v TFSI performance cam tips.

Each engine responds better to more aggressive cam durations so view each engine as unique.

The ecu map and injectors and fuel pump also have an effect on the torque gains you'll get.

Extending exhaust or intake durations can alter the torque band and on most engines the exhaust and intake durations do not need to match, although most cams and tuners use matched pairs there are some advantages to extending the intake or exhaust durations.

Altering your 3.0 V6 24v TFSI cam will make a dramatic difference to the engine power band. Choosing a higher performance cam profile raises the power band accordingly.

NB: Fast road camshafts usually boost the performance across the rpm range, you may lose a little bottom end power but the high end rpm power will be higher.

Motorsport camshafts, boost the high end rpm power band but as a result the car will not idle smoothly and low end power nearly always suffers.

In a road car you must carefully try to optimize your engines power to your driving style.

I would be surprised if you have found a 3.0 V6 24v TFSI Motorsport and race cam is a pleasure to live with when in heavy traffic.

Stage 1, 2 and 3 mods for the 3.0 V6 24v TFSI

Before we break the best tuning upgrades down into stages of tune, let's list the most effective tuning upgrades for you.

  1. Suspension Upgrades - always improve your cars handling
  2. Brake Upgrades - Even before adding power improve those brakes
  3. Intake - make sure the intake is not restricted, use filters and intake upgrades to improve this
  4. Exhaust - as with 3 ensure there is not restriction in the exhaust, cats are the usual bottleneck
  5. Tunes - remapping, piggyback ECU's and aftermarket ECU's can all make decent gains
  6. Fuelling - when you've increased power you'll need to match this with more fuel
  7. Turbo upgrades - Improving the intake with a large turbo and better flowing intercooler will be the biggest power gain you'll see (but one of the most complex).

This video guide to tuning cars is a great starting point to work from in your project.

Stage 1 3.0 V6 24v TFSI parts:

Remaps/piggy back ECU, Intake headers, Sports exhaust manifold, Fast road camshaft, Drilled & smoothed airbox, Panel air filters.

Stage 2 3.0 V6 24v TFSI parts:

high flow fuel injectors, fuel pump upgrades, Fast road cam, Ported and polished head, induction kit, Sports catalyst & performance exhaust.

Stage 3 3.0 V6 24v TFSI parts:

Engine balancing & blueprinting, Adding or Upgrading forced induction (turbo/supercharger), Crank and Piston upgrades to alter compression, Competition cam, Twin charging conversions, Internal engine upgrades (head flowing porting/bigger valves).

Carefully think through your options and then buy your modifications and set yourself a power target to save yourself from expensive mistakes.

Remaps will help fully realize the full potential of all the parts you've done to your 3.0 V6 24v TFSI.

You will typically expect to see gains of approximately 20-30% more power on turbocharged vehicles and you can expect to see around 15% on NASP engines, but the outcome often differs on the parts you've carried out and the condition of your engine.

Turbo modifications on the 3.0 V6 24v TFSI

To get a turbo working on a NASP engine there is a lot involved, from lowering compression ratio to improved fuel supply and mapping, so we have found a great guide to helpavoid the common pitfalls or end up with an unfinished project because you were not told what you were getting into by doing this on the 3.0 V6 24v TFSI.

The more air you can get into an engine, the more fuel it can burn and uprating the induction with a turbocharger upgrade makes major power gains.

When a car is fitted with a turbo tuning mods are more reliable and you will discover turbo engines are made with uprated components.

There are common areas of failure for every engine, with some being incredibly solid and some only able to handle stock power

Research these restrictions and upgrade to higher quality components to cope with the power.

We see many people spending a loads on turbocharger upgrades on the 3.0 V6 24v TFSI only to experience the whole thing catastrophically fail on it's first outing after it's used on the roads.

Bigger upgraded turbos tend to suffer low end lag, and low capacity turbos spool up quickly but do not have the high rpm torque gains.

Over the last 20 years the range of turbo chargers is always improving and we commonly find variable vane turbo chargers, permitting the vane angle is altered according to speed to lower lag and increase top end power.

Twin scroll turbo chargers divert the exhaust flow into 2 channels and feed these at differently profiled vanes in the turbo. They also improve the scavenging effect of the engine.

Beefing up the air intake by adding a supercharger or additional turbo will help you achieve very large performance gains, although more challenging to setup. We have this article on twincharging if you want to read more.

Tips about fuel supply on the 3.0 V6 24v TFSI

When you lift the power you will need to look at to the fuelling.

More power needs more fuel. We strongly recommend you to be generous with your injector capacity.

The accepted safe increase is to add another 15% when buying an injector, this accounts for injector deterioration and affords you some spare capacity should the engine need more fuel.

Don't forget that different fuel grades will usually require different settings, a high octane fuel will burn more efficiently than lower octane fuel for example. A car will trim fuel supply to keep within the ideal air fuel mix but at the extreme ends you may need to adjust your injector capacity, or the mapping or you'll get flat spots and potential lean or rich fuel issues..

Recommended 3.0 V6 24v TFSI performance exhaust upgrades

You should look to upgrade your exhaust system with an upgraded one is if the existing exhaust is actually creating a restriction in flow.

On most factory exhausts you'll find your flow rate is still ok even on modest power gains, but on a serious tuning project with a big boost in power you will certainly need to get a better flowing exhaust.

Sports exhausts can help increase the flow of air through the engine.

But if your exhaust pipe is too large, ie: over two and a half inches diameter, you will lose a lot of your flow rate and end up sapping power and torque.

Usual exhaust restrictions are in the catalyst installed, so adding a higher flowing high performance alternative will help avoid this restriction.

Decatting (NB:catalysts reduce harmful engine emissions) is illegal in most countries and regions.

Faults issues and things to look out for on the 3.0 V6 24v TFSI

Like most engines an 3.0 V6 24v TFSI, should have few issues if it gets properly serviced and looked after.

We cannot stress enough the need for oil changes with the correct grade of oil on the 3.0 V6 24v TFSI, failure to do this will exacerbate engine wear, on a tuned 3.0 V6 24v TFSI this is more important than ever and close attention should be paid to your maintenance schedule.
