hey guys just looking through all the pics of cars, (really nice job on them all by the way - the couple with cannons(im not a fan))

anyz looking through the pics and found this one.....under the strut brace where the TMIC normaly is whats the round tube looking thing on there?

That is what they have used to connect the twins to a Front mount intercooler instead of a Y pipe.

big_smile not too bad of a set up. it takes up a lot less room then the Y pipe design and looks neater too

I thought it looked like a barrel inter cooler. Commonly seen on 4x4's and small TD trucks.

mmmmm looks like we have the makings of a good forum thread....hehehe,

the guy is or was a memeber on this forum joined back in 05 so who knows if he ever gets on here these days: BRAWLA

the thing is soop that there is piping for a FMIC mmmm

Yeah its definatly just the replacement for the Y Pipe.
I have seen the Barel type intercoolers on Subaru's but thats not one of them tongue

So how do they actually work?
Like the WAIC??
Whats the advantage to that, versus the other methods?

i would have to say it would be a water to air set up, other than that im stumpted

does look quite neat though

Yeah, some form of fluid, it runs the hoses to the rear of the car to a resevoir where it is cooled. then sent back up big_smile I beleive it would be fairly effective considering the fluid would have a long distance to travel to cool before it reaches the rear and then on the way back, the set-up in my picture is of the engine bay in a Brumby that had been converted to a new AWD/EJ20T combination.

I reckon seen as though the piping is a lot shorter then FMIC you wouldn't have quiet as much lag. Probably a negligable difference but

So why dont people use these, instead of the FMIC?

I am not sure if they are widely known about or more so they may be pretty difficult to fit, the reason why they don't use them I am not sure. I might look into this I think and find out a bit more.

Cool, i'd be keen if its a better alternative.

Im quiet reluctant to use an FMIC if i dont have to.

AGAINST -

Complexity & Cost. You need a second radiator, water pump & preferably some form of pump speed control, 2 speeds will do the trick. They are much harder to size, this is why we have pumped hundreds of hours into data logging & creating a sizing spreadsheet programme. Under the same circumstances, drive in/out will be approx. 20 to 60% dearer.

It also became apparent after a couple of years testing that I had to down grade my initial cooling estimates of air/water intercooling, which is a disappointment, but necessary. I thought that I could design a system that at speed, would cool the charge air within 4ºc of a front mount - both systems being equally engineered. It appears 8 to 12 ºc is a real world figure. Please put this into perspective. A 'front mount' car - Skyline GTR, 180 - 200 Sx, Supra etc. will give results on a 25ºc day of 31 - 36ºc into the plennum. An air/water setup will give 42 - 48ºc under the same circumstances, but a 'non front mount' car - Skyline GTS-t, VL Commodore, Subaru - any car that doesn't have a front facing throttle body towards the radiator support -  will give similar  temps. due to heat soak in the long return pipe from under bonnet heat - approx 70 + ºc, even though the charge air in both air/air setups, exits the 'cooler at 31 - 36ºc.

FOR --

Now, the above paragraph is the only time a front mount will out perform an air/water if both are set up properly - at speed .  Stop/start, drag racing, towing, 4 x 4 offroad etc. all gain from air/water. The charge air temps. into the engine are also much more stable with  logging showing a spread of  35 to 40ºc around town & 35 to 50ºc laden in soft sand, 2nd gear low range, whereas, front mounts have logged 30 to 65ºc around town & 30 to 95ºc in sand. This is with turbo outlet temps of 140ºc  as for a top mount, 38ºc c to 116ºc have been recorded ! When you have your foot right into it at slower speeds is when detonation is most likely to happen, air/air intercooling is performing at it's worst efficiency. A very big fan under a top mount will make a fair difference & to a lesser extent, behind a front mount, but none can get near the fact that water 'holds' heat 37 times better than air & a thin radiator at the front of a vehicle cools better than a thick intercooler (air flow), & also has much less effect on the volume of air flow too the engine radiator - very important with some vehicles - eg. 70 series Landcruisers. Take a Toyota MR2 & they have no opposition really. Also, this small heat spread allows safer 'set it on kill' tuneups, if that's your need. It also in a small way, helps engine component longetivity with head gasket, top piston rings & valve seats benefiting most.

Another big plus is is with the length of the inlet track. Some cars have a bunch of pipes to get from the turbo to the front & then back to the throttle body - Subaru WRX springs to mind. It's not so much turbo lag as, filling the volume lag.         Sometimes big holes have to be cut in the inner panels for these pipes, so when you go to sell the car, you have to leave the intercooler on as the holes give it away. Two 25mm hoses can be routed to the front so when they are removed, no evidence exits of a performance enhancement being fitted - higher trade in ?, & your air/water setup could be sold for maybe a 50 % return.

Add an engineered ( or even a simple ice bucket) ice water chiller & the results of air/water intercooling over air/air are undeniable. 1 to 1.25 % power increase for every 10 deg. Farenheight decrease, is the possible horsepower gains - note the imperial measurements.  If you have an all out engine combination, this can give you the winning edge - safely !  If you are making 600 hp with 150 deg f charge air temps & an air/water setup reduces this to 70 deg. f. - then a power gain of 60 hp is possible.   I buy most the turbo magazines from around the world every month & have done for 6 years. Over the past 2 years I notice that 85% of featured new drag cars are fitted with air/water intercooling now. It is the only legal way of getting the charge air temperature down near or below ambient air temperature, running petrol. Methanol as a fuel can get reasonably close, & as an injected additive does a good job, but watch the corrosion. Water sprays can be banned at Dragstrips & some Dyno competitions, although fine for the street. 
Big post I know... but yeah I do beleive that the benefits out-weigh the Cons, of which can be negated.

This jigga sounds like the go for long term start stop action. I,e Everyday traffic.

Im not going to use an FMIC.

Re: what is this??????

thats a basic way to connect the turbo pipes together, it wouldnt flow that well either.

as for WAIC, theyre expensive complicated and fairly application specific
great for intercooling where you cant get room for a air to air or run pipework or for drag use when used with refrigerated systems.

theyre not great for track or high load use but good for a city start stop application, although a fmic would stil outperform most waic's

like we have been talking about in the other thread that turned into the WAIC im using a WAIC with a front mount, now i dont c y if u needed better cooling for the IC y not just get a slightly larger radiator part of the WAIC would achieve same as a stupidly big Air IC.

theres more than that to it.
you need Flow through the core.
you need to dissapate the heat
most waic have high pressure drop, you also need to be able to get rid of the heat as fast as it comes in, which under sustained conditions a waic simply wont do.

waic's generally act as a head dampener to soakup quick heat increases for short perids of boost then disapating it through the cooler at the front. a large air to air disapates the heat at a huge rate compared to waic's

running a waic and a fmic is pointless and just reducing flow through the intake
