Now thats just daft.

It would be far more sensible to install a secondary air-con system to keep the fmic at optimal temp

You can greatly improve the airflow of the SMIC location by venting the plastic arch line (area shown in pic)

Just drilling lots of holes will help

Also how about those Milotec front bumper air outlets like rob has I believe, they gotta help also?

One of the best vents I have seen so far is the one from a Hyundai Tucson TDi. But stupid breakers that have them want 20-30 quid posted. they are only £29 from the stealers? I Drilled my arch originally but I have compared the actual area of the holes to some of the DIY vents and a drill is no substitute for a good vent. I recently went DIY with the plastic household vents, I made sure to check the different designs etc and although metal would be nice then are just not efficient. So I have a plastic vent that I have cut notches out of to allow it to bend to the wheel arch liner shape and it has been sprayed black with the good old BBQ paint, I just need to get the arch out and get it fitted. Reason I looked at this was after looking at the way a Boxter is setup, the IC is at a slight angle (so it has increased size vs frontal area of scoop and a good sized vent in the arch. Plan on giving the IC a good clean at the same time as corrosion on the aluminium causes slower heat transfer

Will get some pics up when I get round to it.

Millsey, have you checked out the size of the tyrol sport one yet?

Well, I've done the arch mod using than Hyundai grille.

Bought the whole locker in the parts shop, not the dealer, and it was worth 3 times cheaper.

Here's +36C (97F) by now and it feels running way better after the mod!

When servicing the car in April I also did the full cleaning of the SMIC - washed the pipes with the gasoline and cleaned the fins with pressurized air, its lower third was filled with loads of ****!

Anyway the pipes weren't dirty at all, no oil, no dust, and almost no result - the car ran just as before.

Millsey, we're (here in Russia) watching your progress with great interest and hoping that if you succeed there will be ways to buy the upgraded item abroad! There are no easy or cheap ways of getting the proper IC for chipped cars, so people are making DIY from anything ranging from Chinese ebay cores to some Audi IC's with custom piping, like Rob wrote in his thread.

That is not true mate.

Any wheel arch linner vent fitted behind an Octy vrs standard smic.... inc a B&Q special, Audi TT, Hyundia etc ect, will not improve the thermol efficiency of the IC.

And anyone who says it will, does not understand the basic working principals of how an air to air IC core functions.

Bill.

Please explain? As I was under the assumption that an A to A IC relied on air flow through the IC to provide the cooling (which is one of the reasons that a tube and fin is more efficient that a bar and plate of the same size), there fore any imrovement in air flow should yield an improvement in efficiency. Other wise why would a Porsche Boxter have wheel arch vents? VAG engineers with their hugh R&D budgets must have found some benefit to venting the arch liner otherwise why would they bother with the more expensive tooling involved in producing them?

Please note this is not a flame I really am curious

What about this FMIC from Allard http://www.allardmotorcompany.com/pages/information/pdf/SKODA-OCTAVIA-1.8-TURBO.pdf Keeps piping like robs from passenger side to drivers side so no back and forth of piping from drivers side to outlet on FMIC on passengers side back underneath to the TB. Just an idea.

But of course to eliminate the crash bar problem dont make it as high.

how much is one of these from allard motor company and has anyone got one?

any progress ?

any progress ?

give him a chance!

give him a chance!

its been two whole days, the way he was talking i thought it would only take him a few hours,

only joking didnt read the dates....

Lol, im building the unit next week, should have it fitted and tested on the saturday morning (next week), providing everything runs smoothly of cause :p

Brilliant keep us all informed as most of us I would imagine are interested in this project

I think thats safe too say!

I just remembered another company I visited once.... Pace.

They make a FMIC for the 225 TT and LCR: http://www.paceproducts.co.uk/public_html/php/products_info.php?parent=4&productID=car/auditt

Just for reference.

Guys,

Ive got a couple of questions to ask which im hoping someone on here can help me with:

Whats the pipe diamater on the standard SMIC?

Has anyone got the dims for the MAF flange (centres, diamaters etc)

Cheers in advance

I think the Valeo website has all the dimensions on their drawings

The ID of the pipes connected to the SMIC is 60mm

MAP sensor port is 12.5mm and the screw hole hole centres are 36mm apart

Any update? I'm thinking of going stage 2 so will be needinfg a front mount

Millsey is looking more at producing a decent side mount or TWO :D

.......

soon

? ? what have you heard then ? ?

Agree with that bit, although if i was to make a core to the same size as the ebay ones, it would still out peform it.

Is it a big job to modify the crash bar?

I put the modded crash bar that forge supply up against the standard one and there is not much difference other than a little shaving off the metalwork to accomadate the FMIC then some large round holes being drilled in the bottom of the bar to allow airflow up through the front of bumper through crash bar and into the FMIC, and drilling holes and inserting rivet nuts for the fitting of the intercooler. I have converted a standard one before

I thought the idea of the vents is not to cool SMIC down but let out warm air from the SMIC doing it's job, and thus reducing heat soak?

Also I read this article (2/3rds down the page) explanning the results of a twin SMIC set up which appears very good. (same as S3's) As the VRS may have the hook up points to accomadate the 2nd SMIC for passenger side already? maybe this is a cheaper option to reproduce using better materails over the forge FMICset up and be just efficient as a FMIC.

I was wondering yesterday if twin SMICs wasn't a better idea anyway as with a large FMIC you're obscuring most of the radiator so the engine will be running hotter than it should be?

there is some data out there that suggests a GOOD uprated SMIC will perform as well as a GOOD FMIC and even outperform one in certain situations.

There will be some more info shortly on the uprated SMIC, rather than fitting another SMIC and routing pipework etc over, i think an uprated core will be enough.......we shall see!

I'd be happy with an uprated SMIC, just want to see rolling road figures to make sure its effective. I think I am going to go stage 2 so will defo be interested if they work and are cheaper.
