Improving air intake on the 3.0V6 30v

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

So Feeding more air and fuel into each cylinder is the whole point to any tuning task.

It is not unusual that there is a limit in the air flow sensor AFM/MAF on the 3.0V6 30v when considerably more air is being pulled into the engine.

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

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

Design and rate of flow of the Plenum can make a noticeable effect on to fuel atomisation on the 3.0V6 30v.

It's not uncommon that intake headers are improved through an upgrade, although some car makers provide decently flowing intake headers.

Big valve conversions on the 3.0V6 30v, doing some 3.0V6 30v port enlargement and head flowing will also lift torque, and as an added benefit will allow you to get a better torque increase on other mods.

3.0V6 30v performance cam tips.

Different 3.0V6 30v engines respond better to extreme camshaft durations so view each engine as unique.

The ECU mapping and fuelling also have a large bearing on the torque gains you'll achieve.

A longer valve duration 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.

Significant air intake, and exhaust improvements on the 3.0V6 30v can be made from camshaft upgrades. Changing the camshaft profile alters the intake and exhaust durations on the engine and can dramatically change the torque and power output.

NB: Fast road camshafts commonly boost the power across the rpm range, you may sacrifice a little low down bhp but the high end rpm power will be higher.

Race 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 daily driver you should ideally to optimize your bhp range to your usage of the car.

I'd be shocked if you find a 3.0V6 30v Race cam is a pleasure to live with when driving in heavy traffic.

Stage 1, 2 and 3 mods for the 3.0V6 30v

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).

Stage 1 3.0V6 30v parts:

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

Stage 2 3.0V6 30v parts:

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

Stage 3 3.0V6 30v parts:

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

Review your options and then acquire your tuning mods and set yourself a power target to avoid wasting your time and money.

Remaps will help unlock the full potential of all the upgrades you've done to your 3.0V6 30v.

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 results may vary depending on the upgrades you've applied and the condition of your engine.

Turbo modifications on the 3.0V6 30v

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 3.0V6 30v.

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

When a car is fitted with a turbocharger upgrades are going to net you a larger power gain and you'll see that turbocharged engines are made with better components.

There are reliable limits for every engine, with some being incredibly solid and some just sufficiently able to handle stock power

See where you'll find these restrictions and upgrade to more solid crank and pistons to cope with the power.

There are many tuners spending a loads on turbocharger upgrades on the 3.0V6 30v only to suffer the indignity of watching the car throw a rod when it's been finished.

Bigger upgraded turbochargers tend to suffer low end lag, and smaller turbochargers spool up much more quickly but do not have the peak end bhp gains.

In recent times the selection of turbos is always developing and we are seeing variable vane turbos, permitting the vane profile is altered according to speed to lower lag and increase top end power.

Twin scroll turbos divert the exhaust gases into 2 channels and direct these at differently angled vanes in the turbocharger. They also increase the scavenging effect of the engine.

Beefing up the air intake by adding a supercharger or additional turbo will help you achieve very large power gains, although more difficult to get working. We have this guide to twinchargers if you want to read more.

Tips about fuel supply on the 3.0V6 30v

Don't overlook the need to look at the fuel delivery when you are increasing the bhp - it makes the car more thirsty. It is important to be generous with your injector capacity.

The accepted safe increase is to add another 20% when specifying an injector, this allows for injector deterioration and gives you some 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 3.0V6 30v performance exhaust upgrades

The only time you should look to replace 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 find the flow rate is good 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.

Please dont run with the largest exhaust you can buy this will reduce the exhaust flow rate - the best exhausts for power gains are usually between one and a half to two and half inches. Your exhaust design, the bend angles and construction are what have more effect on flow rates than your pipe width to a certain extent. So the exhaust design is a big factor.

Typically exhaust restrictions are in the catalysts installed, so adding a freer flowing 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 3.0V6 30v

Like most engines an 3.0V6 30v, 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 3.0V6 30v, failure to do this will exacerbate engine wear, on a tuned 3.0V6 30v this is more important than ever and close attention should be paid to your maintenance schedule.
