Improving air intake on the B4164S2 B4164S3

You need air and fuel for an engine to work. If there is not enough fuel then it will run lean, if there is a lack of air it runs rich sapping power which risks damage to the B4164S2 B4164S3. We'll pick up on fuelling later in this article but for now we shall look at air supply.

So it's important to any performance tuning job to shove more air and fuel into the B4164S2 B4164S3 engine but this has a knock on effect with the air flow sensor.

It is not unusual that there is a restriction in the air flow sensor AFM/MAF on the B4164S2 B4164S3 when considerably more air is being drawn into the engine.

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

The intake plenum carry the air during the suck phase from the filter and allow it to be sucked into the engine cylinders.

Structure and flow characteristics of the Plenum can make a big change to fuel atomisation on the B4164S2 B4164S3.

Most air intake manifolds are in dire need of a performance upgrade, although some OEM provide fairly well optimized air intake manifolds.

Big valve conversions on the B4164S2 B4164S3, carrying out port matching and head flowing will also boost bhp, and importantly will raise potential for raising the bhp increase on other parts.

B4164S2 B4164S3 performance cam tips.

Some B4164S2 B4164S3 engines respond better to extreme camshaft durations so set your engine up on a rolling road.

The engine timing and fuel pump and injectors also will say much on the power gains you'll hit.

A longer valve duration can alter the power 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.

The camshaft profile plays a big part in the engines power output so camshaft upgrades make quite a large difference. The intake and exhaust durations will alter depending on the chosen camshaft profile, so large power band gains are on offer for camshaft upgrades.

NB: Fast road cams tend to raise the bhp and torque over the rpm range, you may lose a little low end bhp but your top end will improve.

Motorsport and race cams, raise the top end band but as a result the car will not idle smoothly and low end power nearly always suffers.

In a daily driver you must carefully try to match your engines power to your typical driving style.

I'd be amazed if you find a B4164S2 B4164S3 Motorsport camshaft is a pleasure to live with when on the daily commute.

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 your mileage will rely on the upgrades you've fitted and the condition of your engine.

Turbo modifications on the B4164S2 B4164S3

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 B4164S2 B4164S3.

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.

If the engine is fitted with a turbocharger mods are relatively easy and you will discover turbocharged engines already contain stronger components.

There are tuning limits for every engine, with some being very over engineered and some only able to handle stock power

It is important to find these limits and fit higher quality crank and pistons to survive the power.

We see many tuners spending a lots of money on turbo charger upgrades on the B4164S2 B4164S3 only to suffer the indignity of watching the engine block literally blow up when it's finished.

Big upgraded turbos often experience a bottom end lag, and small turbos spool up really quickly but don't have the top end torque gains.

In recent times the selection of turbo chargers is always improving and we now see variable vane turbo chargers, permitting the vane profile is altered according to speed to lower lag and increase top end power.

Twin scroll turbo chargers divert the exhaust gases into a couple of channels and direct these at differently designed vanes in the turbocharger. 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 harder to configure. We have this article covering twinchargers if you want to read more.

Tips about fuel supply on the B4164S2 B4164S3

When you raise the bhp and torque you will need to ramp up to the fuel system.

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

The accepted safe increase is to add 20% capacity when buying an injector, helps cope with injector deterioration and allows a bit of spare capacity should the engine require 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 B4164S2 B4164S3 performance exhaust upgrades

We'd only recommend you look to improve your exhaust system with an upgraded one is if the current exhaust is actually causing a restriction in flow.

On most factory exhausts you'll see the flow rate is 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 generally help improve air flow from the engine but do not go too big or you may end up will reduce the flow rate. Stick to one and a half to two and half inches as a rule of thumb.

Usual exhaust restrictions are traced to the catalyst installed, so adding a better flowing race alternative will help avoid this restriction.

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

Faults issues and things to look out for on the B4164S2 B4164S3

Like most engines an B4164S2 B4164S3, 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 B4164S2 B4164S3, failure to do this will exacerbate engine wear, on a tuned B4164S2 B4164S3 this is more important than ever and close attention should be paid to your maintenance schedule.
