Blitz Induction Cover + CAI

[Evildoer]

got effect la...even psychological effect better than nothing right? tell ur frend to tape heat shield on metal piping lor...

[Sujoy]

Get the black tubing from Speedworks, durable and non-metal .

 

My stock airbox, done up with heat insulation around it, records in the range of 45 - 50 for its intake temp. Soon I might try insulating a closed pod and see its effect.

[Evildoer]

how much ah??? if i buy from them would they switch my piping for me??? wat brand for closed pod u looking aT???

[Sujoy]

$10 per feet. I doubt they do installation, I DIY my CAI the other time. I'm now back to stock w/ K&N drop-in, I have a Hurricane SS drop-in and a Simota Closed Pod lying around too . I just like to fiddle w/ air-intake .

Well if they enjoy wasting money on meaningless tin cans that add on weight and do jack all to the car, I'm not here to force them not to do it.

 

My purpose is to let people know that the mod will not increase performance. It is my goodwill that if it helps a few people save money, why not ?

 

I'll only dispense my advice once. If they hear it, great, if they wish to be stubborn, too bad. Their money not mine. I don't have the right to decide how they should spend their hard earnt money.

 

But like I said, the facts will show up very clearly on your ECU diagnostic screen / Dyno as mentioned above.

 

As you can see here, so far its all plain talk and no facts and figures.

 

If they still feel that their Butt dyno is more accurate than a $200,000 dynamometer, I have nothing to say.

 

All in all, its plain psychological effect.

[Zyrofillica]

Aiya ppl enjoy doing DIY on CAI mah. They see ppl do they also wanna try. U tell them no effect they very sad cos spend so much $$$ and effort.

 

I try telling my friends only sound effect but they insist they feel something.

 

Then I try asking them the aluminium pipe ducting or the stainless steel air filter aren't these conductors of heat. Furthermore the engine bay is so hot these metals become heaters for the incoming air.

They can shake their heads and tell me it wun happen.

 

I fu le u!

 

then better to do cai with a modified bonnet like an evo 7s bonnet. let natural moving air cool down engine bay significantly.

[Zyrofillica]

so whats the best type of intake for a 2.0l NA auto car with high compression ratio? CLosed Pod SRI?

[Evildoer]

i did experience FC improvement from 560-580km to 650-680km (numbers taken for 4 full tank after mod)...similiar driving style...supposed performance gain is zero...since no dyno...the FC improvement is fact enough for me...

[BMW320i]

As far as intakes are concerned regardless on a stock car, a pod filter typically provides better breathing for the engine.

 

In my opinion, I've been using Apexi Pod intake simply because of its low maintainence and excellent filtration capabilities. If you ever have a look at blitz and apexi's filter components, you would realise that they are relatively the same other than different design.

 

A pod intake or a close pod intake.

 

A (Gruppe M) like the one shown below will do just fine. The only difference you will see is just plain aesthetic.

 

 

Bear in mind unless you have 1 throttle body catering to 4 cyc. meaning, you are using 1 throttly body for each cyc, you won't run into any problems.

 

Benefits of a pod intake ? The response time it takes for you to rev from XYZ RPM to ABC RPM is quicker. However please note that this is not significant because the whole purpose is for the engine to breathe easier. Changing to a lighter flywheel will net a faster response time when reving but this is another story.

 

I said this once but I don't think anyone noticed what I said. Alot of people are going the cheaper option of getting ABC brand of pod filter. If you take this route, you are better off with your stock airbox.

 

The reason why you should get a pod intake or panel intake that is reputable is because,

 

1) Filters all the foreign particles out

2) Reduce turbulent air flow as air is drawn into the intakes.

 

No. 1 is self explainatory.

 

No 2. is important because as air is drawn into the intakes, the velocity before at which the air passes through the filter compared to the velocity of the air that is in the intake is different. The velocity of the air is slowed down due to the filters. As velocity of the air slows down, air becomes distorted and turbulent. As air because distorted and turbulent, the MAF sensor cannot get an accurate reading to feed the ECU. When this happens, you get a very inaccurate AFR. Once again if you dyno the car and look at the AFR charts, it'll look like its climbing up and down erratically as compared to a smooth line.

[BMW320i]

In that case I desperately need to do a CAI on my car.

 

I only manage 380km on a 55L tank.

 

If my FC don't improve, will you have an explaination ready for me ?

[Evildoer]

if ur ride is an NA 1.3- 1.8 auto tranny like thread starter, i would recommend a closed pod with CAI setup...that much i can vouch for... CAI alone do squat....

Sorry, but I can't help it but to ask, what is a closed pod?

 

I've been in the automotive scene for quite a while now and this term "closed pod filter" is getting popular among enthusiats. But what the hack is a closed pod filter? ke ke ke. Did some wizard named it out of the blue? What is the difference between a stock filter element and a "closed pod filter"?

 

Althought the surface area of the "closed pod filter" may be bigger, but the main restriction here is not the surface area but flow restriction of the enclosed design.

[Evildoer]

first pic is the common open pod with heat shield n cai....

 

2nd pic is closed pod with CAI...as u can see...the pod is enclosed in a casing and u attach a CAI piping routing to bumper or foglight area, drawing air from outside engine bay...

[Mroonws]

Is it those open pod filter that has been covered on the outside? Like those simota ones???

[Mroonws]

I don't think your ride will have an improve in FC with the open pod...If i'm not wrong about your car model, its should be about that range...Below 9km/l

[BMW320i]

I didn't say my FC will improve with a pod filter.

 

What I asked was if I had a pod filter and use a CAI method by means of either heat shield, cheapo plasticky PVC pipes from bumper to intakes etc, whether my FC will improve.

 

My FC is about 6.9km/L

 

My previous rex managed 7.5km/L - 8km/L on average

 

My record is 1.8km/L when I brought it to the track.

[BMW320i]

At the end of the day its still an intake.

 

However people wish to design or create special names like Ninja or Hello Kitty powah, its still an intake.

[Mroonws]

i believe what you mean is that the open pod is meant for the engine to breathe more freely not for FC...
