dual cooler idea, 2 singles to make up 1 cupra style ICE

[waynemodz]

hi guys,

im really doing too much research with my fmic move,
just when i thought im going 550x230x65 i decided to check the dimensions of the cupra,

540x390x70 ,
so basically anything under that size will fit...

now the guys say the seat its the IC to have, not everyone can afford the oem cooler,
even myself,

if i look at the surface area of a 230 high cooler is 41% smaller? wud it not be 41% less efficient?
so im thinking what if one went dual coolers (390 / 2 = 195), closes is the 550x180x65
the coolers are 950x stil cheaper than a cupra cooler, bolt them up, 2 90degree's and a straight on the right hand side to link them and also less pipe work on the left side! the coolers are seperated so being on the same side it shouldnt transfer heat.

any comments on this?

Where are you buying and what is prices?

MR Turbo got IC U flow for cheap as well

[waynemodz]

using mr turbo as a guideline but i will not purchase from them, i am in kzn, and their are shops here cheaper than mr turbo.

this post is not about the price or the product,

im focusing on the principal of dual coolers, the efficiency of an aftermarket cooler vs the oem seat cooler vs dual coolers

Using 2 OEM VAG dual SMIC's will be Ok but will not be as efficient as the Cupra cooler. What may work is using the SMIC's off the Q7 or Cayenne for instance as they both use relatively big SMIC's...cost will be heavy though unless you can find at a scrap yard or the like

[Crawler]

After-market cooler like etuners, syndicate or unitronic use vs SEAT - I can't see why SEAT would be better

[waynemodz]

im talking about putting 2 FRONT MOUNT intercoolers on a car,
2 coolers sized 550x180x65.

stupid idea

[waynemodz]

so would you say the seat cupra cooler is too small? so why are tuners using bigger coolers?
we looking at surface area....

i would say a u flow is a stupid cooler when the inlet and outlet are on the same side, i work with aluminium,
it gets hot very quickly, having the inlet attached to the outlet is stupid because on heat transfer,
my idea separates that from happening.

lolwut.... how would that work? if there are 2 intercoolers in front...whats the point of the 2nd one?

thats like us 9n3 GTI/TDI guys running dual SMIC but both the the drivers side back to back...

[boost'd]

just use a normal X flow cooler and run the pipe behind the bumper

a very very long ago I posted this, cant even see the images now but I assume hand drawn stuff

I think the easiest way to answer your question is to direct you to go do more research on heat and mass transfer and material mechanics. Yes aluminium heats up faster compared to steel but it also cools down faster hence its use in many automotive applications. It also has a lower mass, good corrosion properties etc. When it comes to the cooling, heat and mass transfer,cross sectional and direct surface area will play a big role.

It does not necessarily mean that the bigger surface area will give you more cooling as the cross sectional area and width of the cooler can also give you gains. Also you need to look at the pressure drop across the cooler for your application. It's not as cut and dry as it might seem.

Oh and by the way the efficiency of the cooler cannot be assumed to be linear as in reduction of reduction area.

Not behind each other ,stacked on top of each other, im talking bout core height.

even dark side deveopments used high sized core IC's.

its like taking two coolers and bolting them together....

have you guys logged FMIC straight flow temps vs FMIC Uflow vs SEAT OEM?

or do you just do a fmic mod and are just happy with the difference it made?

i do not think a fmic 230 high is efficient for high boost application.

[SHAUN]

Run a twin cooler setup like the S3's



Cupra R setup

[MouseGTI]

eh, i'm not entirely sure that'll cure whatever problem you may or not have...

why not just go one FMIC with a thicker core? fabrication for your idea will be a b!tch of note...

[waynemodz]

@shaun doesnt meet my requirements

@my gti, 70mm is the max core i think it can take without grinding the crash bar.

i dont have a real problem, i would like a 2bar and above setup to run efficiently.

My Audi has a dual SMIC setup, it is ****...

[waynemodz]

look at the etuners cooler...

note the welds... its two single coolers joined.

if everyone had unlimited funds no1 would ask these questions,
they wud leave their cars at tuning shops...
and just pay..

people who cannot afford tuner kits or the oem cupra cooler
go for fmic kits,

now lets think out the box...

2x Straight flow coolers R2000 + 2 90deg bends (R300) + small straight joint (100) and 4 clamps, R100
R2500 ive got a cooler with the same application style and surface area as a cupra or tuner cooler worth over 5k.

even if i spent R1000 on piping, fit it myself,
and i saved over a grand.

to remove the bumper its easy, anyone with torx screw drivers can do it.

[boost'd]

etuners cooler is a cut and weld.
they cut the inlet off one side and weld it on the other side

[waynemodz]

compared too the cupra cooler





note to etuners / other tuners i got nothing against ur guys products,
i just have a personal preference on how things are done on my car.

I dont see the dual smic setup working there is limited space on the right hand side with the window washer bottle, horn and power steering pump.
The intercooler is only as good as its core, it may flow well but lack in surface area to cool the air enough like the smic or it could cool very well but it could have poor
flow due a dense or poorly designed core. Fit a cooler that meets your cars spec ie size, spacing and flow orientation and if it ends up not being very good at cooling just add watermeth later. If I could of I would of done the cupra cooler from the get go but it would of worked out too expensive with the brackets and piping, but knowing now a little bit of ally would make the brackets and then get the pipes made up. Yosh was telling me from my cooler the mr turbo one cooling wise is around 10 -15deg hotter then the cupra one with watermeth would sort out but whats the point might as well go the new cooler as I dont have to buy meth and water all the time and the cooler is around the price of a good WMI setup.

[Killerwatt]

Honestly, there is nothing wrong with your idea.
Having the 2 coolers may be a bit of a hassel to install and fit but it will work. You will get a bit more pressure drop though.

The way E-tuners does it is a neater and easier way of doing it. Doubt there will be any difference between your 2 seperate coolers and a single one modded to dual pass.
Get the tallest single pass cooler you can, chop it up, do some welding and bobs your uncle... Just make sure to seperate the inlet and outlet with a bit of aluminium so that the air flows through the cores.

[waynemodz]

@ boost'd , i never think of that! makes way more sense!

[dazza]

have you guys logged FMIC straight flow temps vs FMIC Uflow vs SEAT OEM?

or do you just do a fmic mod and are just happy with the difference it made?

Well the SEAT cooler is very efficient and is used overseas on cars that do serious power. That being said depending on your specs etc there may not even be a need for you to run two FMIC's, one may be enough.
You can get a cooler in the same dimensions as the SEAT cooler for probably cheaper than the SEAT unit if you look around so in my mind one bigger cooler would be more efficient than two identicle smaller units
