Subject: Car Talk - Air Induction / Intake

I_was_ going to spell the thread title ‘talk’ as ‘torque’, for fun …

Anyways, I’m really keen on replacing the factory air box with a performance air induction kit on my SV6

They all claim better overall performance than the stock units, citing more power, better throttle response and improve fuel economy.
Anyone have any experience with this upgrade?

The two that interest me are the SS Induction’s ‘Growler CAI kit’ (using a pod filter)

or
The OTR (over the radiator) style, with either the pod filter or panel filter.

My logic makes me think that the OTR type would perform better or more efficiently??
As it provides a much shorter pipe which also has a ‘straighter flow’ directly into the intake manifold. Plus drawing cold air directly from the front grill region.
But what about the heat from the radiator?

Where as the first type above only provides improved box and filter section, keeping the existing length and type of curved pipe.

Any thoughts?

I asked a simlar question a while back on the other forum and the answer was the systems improve performace by drawing in colder air from high up off the road and before it went through the radiator.. Any Air-Ram type effects were marginal at best.

The performance improvement would only be one or two percent with either. The purpose of these kits are to make the engine sound better, and most people think that it goes faster because it sounds like it does. The stock inlet system is pretty good, a lot of design went into it to make sure it was not restrictive.

As long as the inlet pipe is a large enough diameter, it does not matter how many bends are in it as the engine will get plenty of air anyway. The length of the inlet tract from the valve to the plenum does have an effect, but that can’t be changed without replacing the whole inlet manifold.

Often the easiest performance improvement is to fit a better exhaust system.

So Kingy, are you saying that the claims made for these air induction kits are bollocks?

They all claim a power increase of up to 12kW rear wheel. (6 cylinder)
Better throttle response and better fuel economy.
The stock square air box on my car doesn’t look very conducive to smooth or efficient air flow.

Sure, a new performance exhaust will do great things however that costs a crap load more than an easy fit cold air induction kit.
Especially with a stailess steel exhaust, then you need to re-tune your engine.

The claims are usually vague enough to cover any lack of power increase. “Up to 12kW” = anything from 0 to 12.
Better throttle response and economy could mean as little as 0.0001%.

Ask for some independent dyno results.

it also makes me wonder if you had a venturi system being used for the exhaust that you could draw the exhaust out more effectively by creating a low pressure zone in the exhaust

air passing over the exhaust area would draw exhaust from the engine

the faster you go the more efficient the engine becomes

Um, I don’t think so.
The A/C’s compressor is run via a drive belt, usually off the crankshaft pulley.

In other words, it is a mechanical load, not an electrical load.

*although the system as a whole does require some electrical power for full operation, the “power loss” from the engine is mainly due to the mechanical load of the a/c.

I think Wookie is suggesting it be replaced with an electrical drive, in which case it would reduce the mechanical load.

There are quite a few things to consider regarding the a/c load, such as local weather conditions, vehicle glazing, vehicle skin, amoungst others. The range could be anywhere from 1kW – 4.5kW

http://www.nrel.gov/docs/fy00osti/28960.pdf

Next time you’re out and about have a look at the size of a 2kW or 3kW pv array on someone’s roof.
Then consider the logistics of incorporating this into the vehicle’s exterior.
Don’t forget you then have cloudy or rainy weather to contend with and night time driving.

you can get solar cells with higher efficiency that the ones on the roof

perhaps you could use the cells used by the solar challenge/race dudes who travel around australia?

i’m also thinking that the shading on the windows could be solar cells as well (as in tiny dots)

you could fit an electric motor to assist the turning of the wheel connected to the AC compressor or fit the motor to the otherside of the compressor

it could just be driven by an electric motor rather than driven by a pulley

i’m thinking that you could have a dedicated unit that incorporates the compressor and motor together – when it goes kaput the whole thing comes off without touching the pulley wheel

one problem is that as energy is transformed there is always a loss, this loss might be more than made up for by the solar cells

another thing to consider is this

car design might change

an I-load for example would have much more light gathering capacity on its roof than a car, its virtually flat and can be mounted by simply using the roof racks

you might use a photovoltaic system to make the car more streamlines at speed that is air is pumped to strategic parts of the car to make it more stream lined and keep bugs from smashing themselves all over the body

what about this foir a crazy idea

instead of having air rushing in through the grill you pump air around the engine using PV cells and eliminate the grill

you even might use the passing air to help suck air through the engine cavity like a VW beetle (though there is also a fan to do this)

instead of having a pulley to turn a fan there is an electric fan to do this?

if you drove of a night you’d need open up a grill to allow air in.

what about this

you use solar cells on top of trucks, the surface area on a truck is huge

the best way to improve economy is by dropping the weight of the car

cars will be accelerating and deccelerating make the wheels lighter and body work lighter. the bonnet could be made from something lighter rather than metal.

maybe we could make cars on an injected plastic production line?

making the bosy and chassis of the same material could make it easier to recylce

maybe cars should be designed to last for a long time

maybe when you buy a car it should last maybe 7 years then be recycled , this way components within it are designed to last for a shorter period than 10-20 years?

with each component designed for a much shorter period the component would be lighter?

what about this for a freaky idea? over the lifetime of the vehicle less or no major component would ever need to be changed ie timing chains – you could design spark plugs to live in the engine until its scrapped

when you buy a car , in the 7 years you have it you’ll rarely need to visit a garage except for brakes, steering etc. airfilters can be changed by the owner, that is you save money on rarely taking it to the garage.

normally you might spend 700 – 1500 dollars a year on maintenance over 7 years

you could make the draining process mess free so it could be done by the owner without getting covered in oil, the owner changes the oil and filter and the sparks stay in place.

you have NO/ LITTLE re sale value , the car simply returns to the dealer and brand new car is sold.

buying a car would become like buying shopping in the end AND you might actually BUY cars at the supermarket, you drive in and drive out with a car bought at the supermarket. COLES and WOOLWORTHS might just become the next car dealers.

A further 1-2% each might be picked up by fitting a bigger throttle body, porting the head/s, fitting headers &/or free-flow exhaust, playing with the EMS… Tune it like a madman, run the best oil and fuel…

Spend a small fortune and half a year and you’ll still have a slow old car.

cars normally have insulation inside to stop radiation from the metal. if you made the body from something naturally insulative then the heat inside wouldn’t be as much. if the windows stopped heat more effectively then again less heat would get in

    I know from reading, that the ECU’s on the SV6 VE commodores come out of the factory quite ‘flat’ and some simple firmware changes combined with some basic air flow mods can help, not only improve fuel economy but improve engine responsivness.

I can see some truth behind the first point except that they are competing against other companies that are not all in the same position of the model cycle.

Point two says you can sacrifce reliabilty for performance. That ain’t rocket science… and once again the car manufacturers probably have picked the best compromise.

Well they do, they are competing with other companies but they do like to increase the performance of their own during its facelifts, point two is a bit of a reverse, they sacrifice performance for reliability. If careful owners are willing to spend more on maintenance they can access greater performance. This is one of the many reasons why they generally void warranties.

Today’s cars have changed so much over recent years, with the advent of car ECUs that take control of all aspects of car management, from the maximum power and torque an engine delivers to its economy and driveability. Whilst the huge advances in technical management of the way your car drives have made it far simpler for the consumer, it also means that tuning cars has become a far more complex task involving many small variables that can effect the ways in which your car performs.

Cars are usually manufactured with their stock ECU settings made to suit highest point of stress tolerance, meaning that they have conservative settings for power delivery and often run the engine ‘rich’ to deal with variances in climate and ‘worse case’ conditions that they may encounter. Because of these highly conservative’ restrictions placed on the engine, simply re-tuning the ECU can deliver a good increase in engine performance and increase in fuel economy while still keeping the car well within the boundaries of safe operation.

Cars are usually manufactured with their stock ECU settings made to suit highest point of stress tolerance, meaning that they have conservative settings for power delivery and often run the engine ‘rich’ to deal with variances in climate and ‘worse case’ conditions that they may encounter. Because of these highly conservative’ restrictions placed on the engine, simply re-tuning the ECU can deliver a good increase in engine performance and increase in fuel economy while still keeping the car well within the boundaries of safe operation.

Interesting comment about running rich. I wonder if it would help with my DPF problems?

The bogans on the 4WD forums reckon retuning the ECUs in the newer diesel 4×4s makes a large difference to either power or economy depending on which they want.

I was just looking at one site that says it offers a DPF removal remap in some cases. My main worry about removing the DPF is blowing up the turbo.

Yea, I considered it, but there were stories of blown engines or poorly performing engines.

What about replacing the ECU? If it doesn’t work that good put the old one back, is that possible?

One site says that they will retain your original settings and put them up in the cloud.

It would seem to me that they should be able to do the whole thing over the internet if it is just a re-programming thing.

There seems to be some copycat activity happening.
I have just emailed this mob

I guess it’s possible that some remapping or ECU adjustment/firmware changes could be done over the internet.
Although you’d probably need the correct adapter for the comm’s port on your vehicle, connect via a notbook with wireless connection (unless you have a workshop setup with easy access internet) Then you need to load the right drivers and software to interface etc.
It wouldn’t be a ten minute job.

From what I’ve discovered so far, you have to have appropriate software program for your vehicles ECU for a start, to make any changes to its firmware.
You wouldn’t want to stuff things up!

From my experience in electronics, it is possible to damage an EEPROM (Flash Memory) if things are not done correctly and could turn out to be an expensive mistake if one screws things up.

It is all beyond my ken. I have had a response from the UK company I linked earlier. They say that they have agents in Oz. I have replied and asked a few questions.

Ok, cool.
Do you want to disable the DPF on your diesel vehicle or genset, morrie?

It is my vehicle that is the problem. I have just had a response from the bloke in the UK, indicating that he will follow up, so I will see where it goes.

Well, it’s currently 10:20am in Manchester, so if they’re not too busy they might get back to you tonight.

There used to be a radio show called ‘Beyond our Ken’. I enjoyed that. It is probably played somewhere in the wee small hours today. A bit like ‘My Word’ or ‘My Music’ which I sometimes hear even now.
