Hi, so I’m looking at purchasing the FMIC in the pic. 
1, I just want to know if anyone had any experience with this and if it was a decent fmic? 
2, my car is already stage 1. If I fit the fmic will it need to be mapped again or can I just plug in and play etc. 
 

Thanks in advance!  

The standard intercooler on a VRS is side mounted so it isn't going to be plug 'n' play.

 

There will be bodywork cutting and drilling necessary, if you're not skilled or tooled up for this then it's probably not worth bothering since a FMIC really only brings benefits with bigger turbos.

...and no, you won't need another remap because you aren't increasing anything so no more fuel is needed.

No, but there's no point unless you're doing further tuning and/or racing the car.

 

What would be a good idea is one of the variations on a Swiss cheese, pikey or Audi grille mod for your RH inner arch, to let out more hot air faster.

I have the opposite problem of a hybrid 1756 with the standard pipework and SMIC - car is mapped and Ive never had anything nasty like boost leaks, limp home mode or heatsoak happen mine 

 

Well I do give an odd bootful now and again but not on a constant basis and the car still exceeds my expectation ! 

 

I know that mine has a lot more potential and my next step is to fit a FMIC and hard pipe kit but at the minute its well down my priorities. And I aint going tracking or rallying my daily driver Ken 

 

If I was to go for one the common fitment is an Airtec which a search on this forum will reveal an absolute treasure trove of info on fitting and pitfalls that others have experienced !

How good that one you came across is hard to know but If you do decide to get one the true potential will only be revealed after a bigger turbo is fitted.

mines been a nightmare, everything is standard atm except a stage 1 remap running just shy of 180bhp. And the boost pipes keep popping off because the clips are worn. Replaced and put on egr delete with all silicon tubing to replace the standard boost pipes which worse fine. But then the next standard connection further down went. Tehn the next and now I’m all the way to the smic near enoigh and it’s just a bit of a bodge and I still can’t blast it 🤣

 

so that’s why I’m looking at a fmic plus for when I get a big turbo in the next few months 

 

I’ve messaged the company asking what potential their fmic is actually capable of. I don’t mind spending the money if I need to but if I can get the same gains from a 350 unit than a £600 unit it’s a no brainier don’t like paying just cause it’s ‘airtec’ or ‘dark side’ etc 

Just repair the standard pipework using self-tapping screws instead of relying on the clips.

 

It isn't a petrol engine so a FMIC on a diesel just doesn't heatsoak so quickly when on full boost, it doesn't improve power or reduce detonation, it just reduces the rate at which it loses power.

 

It's nothing like a petrol turbo at all in fact.

Ah, that's a very different question then. There's no need to remap with a FMIC itself, but you will need a remap with the big turbo, and it would be best to have the FMIC in place first.

 

Oh and ignore anyone who tries to say that the gas laws don't apply to diesel engines. If that were the case, why would TD engines even have intercoolers?

Heatsoak Ken.

 

Heatsoak loses power.

Ok, now read the actual facts - Gas laws - Wikipedia . Do you still say that compressing air with a turbo doesn't make it hotter?

Did he ever say that?

Please stop Ken.

 

Hot intake air on a diesel simply reduces power, on a petrol engine it cause pre-ignition which destroys engines.

 

Theory crafting Ken, I haven't looked at the gas laws since university, out here, experience is king.

Before going bigger turbo when I just had a remap I fitted an Airtec FMIC and it made a noticeable difference, I was surprised as I was not expecting any difference, some of this is probably due to the horrible leaky original connections.

 

If you watch this video from Darkside he says a FMIC on a remapped VRS will add 10bhp every time.

 

I can recommend the Airtec FMIC, the intake temps sit between 5-10 degrees above ambient temp however I drive which I think is very good, you do though have to cut the crash bar, trim the bumper and cut off one of the bumper mounts for it to fit.

Come on cupcake, he's SELLING it and you bought it.

 

It can't add power because a diesel needs more fuel to make more power and that comes from a remap, what it does is reduce the power fade quite dramatically, probably by about 10 bhp!

 

Mugs.

So I gather from this thread that its not a direct power gain, it just stops loss of power from heatsoak.

When we had that heatwave a few weeks ago my monte was getting quite toasty with inlet temps. Usually keeps around 30°c and during all the heat it was getting over 40° and peaked at 50° more than a few times. Its got a front mount intercooler standard (albeit a rather small one). Take it with a pinch of salt, but it did seem to blunt the performance of it a little.

I'm guessing some proper heavy track work would do the same. On the opposite end of that, my monte absolutely loved the crisp cold air we had over last winter, Definately noticed a bit more punch even with it being then a mostly standard 105hp car.

Wellycooler style intercoolers used to be a cheap way to go for putting bigger intercoolers on VAG cars. 

I do intend on changing the intercooler on mine in the future, darkside ones seem the best job, but it seems to me that its "just" a bigger intercooler with 90° bends welded on to make it fit easier, nothing some 90° bend silicone hoses can do the same for much less. Not knocking Darkside in the slightest, I have one of their downpipes on my cars and they're a nice bit of kit, the welds they did to it were done to a high standard. 

 

An intercooler with alloy ends performs better than one with plastic ones (standard). Black intercoolers also perform better.

 

*Grabs popcorn*

Blah blah blah usual sepulchrave knows better than anyone else, give it a rest cupcake.

No need for insults, everyones opinion is as worthy as someone elses, its how we learn.

 

Can you describe what this "heatsoak" is and how it reduces power for my knowledge please.

 

I am very late to the party with diesels having spent most of my life trying to squeeze more power out of petrol engines, with them its a fight against voluletric efficiency, the more air you can get in to the cylinders the more fuel you can add, the more power you will get, turbocharging gets more air in but its less dense and contains less oxygen when the pressurisation increases the charge temperature following the gas laws plus the heatsoak (maybe its that you were speaking of) from the exhaust gases on the turbine impellor, an intercooler will increase the density of that charge and hence increase power.

 

Thats for a petrol engine but as you point out in most of a diesels operating range there is no shortage of oxygen and its only by limiting the fuelling that the engine does not run away, I think the forced induction increases the rev range beyond which the engine would struggle for air, I can see that a better intercooler, assuming that the standard one is lacking  could increase power at the highest revs or increase the point at which the power falls off, I doubt that it would make any difference in normal driving conditions.

Blimey, it was hardly an insult!

 

Not every opinion is worth anything, most people know sweet FA and just parrot rubbish they misheard down the pub, to learn about stuff you have to STUDY and learn the facts, whether that's in education or the workplace.

 

There are opinions and there are facts, they are two different things entirely.

 

An intercooler acts like a heatsink, it absorbs heat from the air travelling through it depending on it's mass and its internal area, therefore a large intercooler can generally absorb more heat from the pressurised air, it can also exchange this heat with the outside air which is why front mount is better, no intercooler can reduce charge temperature below the ambient air temperature so the most power an engine can make for a given boost pressure occurs before the intercooler starts to get hot, this is heatsoak. As the temperature of the intercooler increases the power drops, a FMIC is worth about 10 bhp less power drop than the standard SMIC.

 

Thems the facts, form your own opinion.

I couldn't agree more although it's a bit last century thinking that the parrots swallow their rubbish while down the pub, they have this new feeding station called the interweb now Same junk different shop!

 

You are not alone, I for sure am stuck in the last century,  a better place and the best place for me.

Or, put the other way, an FMIC suffers less from heat soak, so you can map more aggressively with a custom map and make more power.

No, the stock turbo won't do any more, it flies to bits, but you can fit a bigger unit that makes more boost.

What is this "heat soak" that an intercooler is supposed to suffer from?

 

Surely heat soak (transfer) is its raison d'être?

 

Unless I have misunderstood or the wrong terminology is being used then a FMIC far from suffering from increased heat soak would benefit from it.

Heatsoak is where the intercooler gets hot and cannot lose the excess heat quickly enough leading to a big rise in delta T which is shorthand for the difference between the charge temperature and ambient.

Delta T is the entire raison d'etre of an intercooler, bear in mind that it's not long ago that many turbo diesels didn't even bother with intercoolers at all because hot air actually improves diesel combustion, guess what glow plugs are for, hint: they're not for warming the cylinder head.

If you'd bothered to read the thread properly instead of doing your usual "I'm right and everyone who says something other than 'yes sir, how high sir? three bags full sir' is wrong" you'd have seen me say that up-thread.
