Front Mounta Intercooler - dissappointed

Are you guys saying I could potentially convince the little miss that an FMIC would increase fuel efficiency?

Yes! If you have power ready to be delivered, you will use less throttle.. less fuel..

[Plautos]

on another note, yes mods will 'free up the engine' so to speak, but only to a certain point. mods past this point (don't ask me where it is) will force more power out of the engine, beyond it's capabilities. i don't believe this forced power was already there and it's just been restricted.

You are right, however if you start changing mechanical parts of the engine, you are giving to the engine new limitations… and that is other page of the book…

[Plautos]

Plautis, thats kinda like saying i already have the fuel in my petrol tank, so how can a bigger set of injectors increase my power?

most mods are about actually realising a cars potential. Yes, a stanfdard turbo will deliver well on cold days, but how often do you get this. The FMIC will deliver colder for longer, thus realsing more of the cars potential

If you are using larger fuel injectors, you should have more boost to compensate.
One don’t work with out the other, it’s always a war. If you use a larger fuel injector, the ECU will try to compensate. If the injectors are too large, the ECU will not be able to correct the fuel mixture. You will spend more fuel, and lose in all other aspects.
The worst thing you can do is change the fuel injectors in a Stock ECU.

You have to understand that the ECU doesn’t know how much fuel it is injecting.
It knows when and for how long the injector should be on and off. It corrects the fuel mixture by the Lambda sensor at the exhaust pipe. But always inside its limitation.

If you want more power you should look first where the engine is restrictive. If after that you are not satisfied be more radical, go for a new turbo and ECU software.


For example take a look on the problem I’m fighting.

My car is chipped, however it have a hi peak of boost.. at this moment it is running lean.. after that, the pressure reduces and the mixture go back to rich again.

All right..

Therefore in my next tune I’m going to install a FMIC, that will bring more efficiency to the chamber, so to make a good burn more fuel will be required… and I don’t have it! That’s a problem! I will need to change the fuel injectors or the FPR and I’m hopping to let the ECU alone. But why? Because the changes I’m doing are getting out of the “flight envelope” of my ECU.

Haha Plautos, your statement is only hypothetically true. In reality, you will spend much more time with your foot buried to the floor harder, and will use more fuel!!

Hi,

I dont know how it could be installed wrong? cramps on site yes, hoses on correct yes. the cooler bolts up to the crash bar so that cant be wrong either..

There are no leaks the clamps hold it together very well..

The intake hose last time i checked was boiling hot. that is after intercooler..

I dont see how the intercooler will cool that hose in any event. The underbonnet temps will make that hose hot.

I just dont think the stock cooler is that bad.. A bit of hysteria.. The tests must have been done under the most extreme conditions to feel any difference.

[shaneth]

Mate there has been many dyno runs done both before and after putting a fmic on and also comparing a stock inlet temp to one with a fmic and all the proof is there. It does give extra power and decrease inlet temps. and it does make the hose to the throttlebody cooler as i have gotten out after a run with sharkie and felt his and my TB hoses and the difference was amazing.

HAHAHA thats true!!!

Yes, it will be hot.
The intake manifold it is just behind the radiator, the hose delivering air to the intake is also positioned where it will take a bath o hot air from the radiator.

But don’t think the air inside the hose is hot just like the air out side. If you want to improve ventilation inside your engine compartment, remove the black noise protection and the rubbers from the hood. I felt difference, and the engine sounds good inside the car.

Hmm this might be a little but off topic. Just want to ask, from my understanding...

Fuel consumption is based on the work done on the car. Now if it takes, say hyphetically, 90kw to move your car to a speed of 100km.h. Now after having inter miler n larger injectors installed into the car, wouldn't it still tak. Just 90kw to move ur car to 100km.h

So even if tour car can produce 200kw, si your fuel consumption (work required) will still b the same if you have only 90kw?

...

As said before wouldn't the benefit of a Fmic sill only be shown with a tune because of the stock ecu parameter o ly limited to a certain leeway. This flexibility is what gives you that extra power you see in the car.

[Chipped]

ok so can one expect to 'feel' the extra power the FMIC produces (aside from eliminated heatsoak). Can you feel it through the accelerator? My car with stock SMIC (APR V2) the a FMIC (with APR V2) would I feel it?

Tnx

If you are talking about acceleration, no. If you give full throttle, the engine will require those 200kw and will feed then. Now if you drive looking for fuel efficiency, yes, you will only use 90kw.

Do you know the difference between torque and kw? Torque will put your car to move, kw will give it speed.

Yes, you will get torque! You are not going to fell the car weak anymore.
If you drive it in a hot afternoon you will feel the response of the car like driving at night.

It will give you better results.

Hey Petrina Polo. How is the FMIC going? still disapointed?
In hindsight would you do it again?

[Spec83]

Check to make sure your turbo is not overboosting if you have some sort of re-map... Sounds stupid, but overboosting to a non-efficent part of the turbo curve would cause intake temps to rise dramatically negating the effects of the new FMIC.

This is what happens with a lot of jap cars with aftermarket boost controllers
