E68

[E36UDM]

Airmax2 is identical to E68 Maybe u can try Green filter out

[E36UDM]

If you intend to take in cool air then u shud be doing CAI instead.

Hi Coyote.

 

If you wish to achieve better fuel consumption, the best way to do it is to be careful with your driving style. Hard acceleration can burn up to twice the amount of petrol than casual push offs, while you gain zero benefits from time savings (after all, when a light eventually turns red and traffic stops, even the fastest cars will have to halt, and the slowest ones will catch up). And from certain air-fuel ratio readings I came across in the past, engines are usually programmed to run with lower air-fuel ratios at higher revs (e.g. 4000 RPM and above), which means more fuel being injected given the same quantities of air. This doesn't work out well for fuel consumption.

 

As for AirMax2, it is identical to E68. Perhaps they come in different colours for owners to show off on highly infrequent occasions when they pop their hoods off for friends to see.

 

I have spoken to some highly competent mechanics on E68/Micro compressor/AirMax2, and they can readily tell you that such implements don't improve your engine performance at all.

 

VenturiOne and Ecotek work a little differently by using an engine's vacuum to bleed in air from a different source (i.e. the brake servo connection). These little gadgets do have much better air filtration properties. However, for fuel savings purposes, gains, if any, may be negligible. If you seek performance improvements, I suggest you test these devices out first before committing to a purchase.

 

As for performance filters, they will give you better pickup (again, at the expense of fuel economy), but you'll have to keep replacing them with similar items (which cost more than stock standard items) at service intervals.

E36UDM,

CAI=cool air intake? pardon me, i v novice duno term used.

is it take away resonant box and re-position intake hose

opening to draw cool air from outside engine bay? i

understand can b quite noisy.

[S2P2]

not a noise you cannot live with

[Hitman]

The information you provided is very timely.

Actually, I am thinking of installing E68.

My purpose of installing it is mainly for better FC.

 

As mentioned by you, VenturiOne & Ecotek are better

as compared to E68. What about AirMax2?

Do all of the above have same functions.

 

So am I right that we should just change to a better

air filter (like K&N - which I had) and stick to the

stock.

 

Thanks.

 

Bro I must say .... better FC is not wat you should be looking at for the E68. I also realised this ... its not a such a good item to have for top end speeds.

 

Was going up to KL and I had to shut off the E68 was top end acceleration was suffering with hesitations ...... It is only better used for the lower ends.

Hi Silverarrow,

my objective of adding E68 was actually to take in more cool

air as i experience much better ride at nite

(when air is cooler). guess it din

work cos maybe come in effect only above 3500 rpm or wat.

 

cool air mod may be the next option but dunno how noisy.

ADM advertised in wheels mag.

wld certainly prefer a simple add on if possible.

 

cheers.

 

Hi Lazy.

 

I'm not exactly sure why you'd want cool air in your engine.

 

The reason why turbochargers needed to cool down scorching hot gasses fed into engine cylinders is to enable better compression from forced induction. And they cool down hot gases via intercoolers.

 

But for normally aspirated engines, I don't see much benefits from cool air intakes. In fact, from my experience in chassis dynamometer tests, we needed to let the engines warm up sufficiently to extract more power and get more consistent readings.

[Coyote]

Appreciate your lenghty explanation.

So I guess, have to give E68 & AirMax2 a miss.

 

Does VenturiOne and Ecotek, similar to Capsule?

Cos Capsule also uses the brake servo connection.

 

[Coyote]

Thanks for sharing your experience.

Actually intent to go up to KL early next month.

[King]

with the ecotek, cai and K&n is still ok........FC suffer only after installing the capsule

u put so many thing.....

capsule?nigel put where for u?

hello Silverarrow,

cos in sunny, an air-intake is in engine bay. it draws in lots of hot air

(less oxygen) therefore combustion presumbly not very efficient.

response is much better when driving at nite so i guess cool air (more

dense) is d trick. dunno whether correct??

[Silverarrow]

Sorry to say this, Coyote, but I'm not familiar with this Capsule thingy at all. It looks kinda huge though, so I don't know if it can fit into some compact engine bays.

 

If the seller allows you to try one out before buying, perhaps you may want to give it a go. Don't commit to a purchase before testing, unless you're absolutely certain that the seller has a full refund policy in case you're not satisfied with the product.

The air in the engine bay is taken in from the environment. Thus, oxygen content is the not affected. I'm not exactly sure what you meant when you mentioned that you get a better drive at night.

 

Personally, I find my vehicle's engine to be at its harshest when starting off cold in the morning. At noon time, the engine performs much better, and it's no different at night.

 

If you only drive your car to work in the morning, and drive it home from work in the evenings, you'll definitely have a better drive later in the day, due to higher ambient temperatures that built up during the day.

[Lazy]

drive alot during work ,unless idle

[E36UDM]

cold air has more mass or denser, so more fuel can be burned for the same volume of air. This would gives u better power Thats why intercoolers are impt for TC cars.
