hey guys i just recently got my fmic fitted, and it is kinda defeating the purpose, my intake pipe is straight above my fan and my pipe is getting quite warm, why have a fmic to cool the air, if it is just gonna heat up in the pipe again? is there any type of covering i can put in between my fan and piping to stop the heat transfering from the hot engine air??

or would it make any difference at all?

its pretty dumb really, but all the piping kits route the cold pipe past the radiator.

the best way would be to customize your piping, so the hot pipe from the turbo runs past the radiator, an into the drivers side of the cooler.

then your cold pipe can run the standard route from passenger side into the plenum. its a shorter distance, and doesnt pass through any hot areas.

oh ideally yes that would be great, but i dont really have the cash to do that being custom and evrythin, my best bet would have been to go for the same side/ entry/exit cooler, but we live and learn, is this a common problem with us rb25 folk? what are u others doing to prevent heat transfer or are we just dealing with it?

Is it just me or would that make the piping length massive? :yes: Still has to come across the block to go into the plenum as well...

But yeah even though the pipe gets warm the cooling effect you are getting very easily outweighs any problem with making the air a bit warmer around that pipe. To be honest I'd never really thought about that, but I wouldn't worry at all about it. When I first fitted my fmic it came across the same way, but now my piping is modified on the drivers side and doesnt go anywhere near there :blink:

yeh fair call, it just pisses me off to know all that effort to have no change! even though the piping gets hot, would the air inside be same tempreture?i might get a vented bonnet ???remove some of that hot air, i know for a fact the cooler is working becuase its cold before it enters the engine bay then warms up like FARK

yeh true, just want my car to be getting the best out of what mods i put in :yes: might try some heat shielding tape or something! is there a way to test intake tempretures? from intake piping?

You should have asked me about it yesterday :santa:

The heat transfer from pipe to air will be negligible as the air is moving pretty fast and compared to the volume of air passing through, there is very little contact area. As mentioned, you can wrap it. You can also space the bonnet up off the hinges if you're worried about under bonnet temps. As for intake temps, you'd need a thermocouple inserted just before the throttle body with a seperate gauge.

OIC.

so tis will affect all rb25s?

im driving a r34 gtt and i was planning to purchase a FMIC.

so should i just get the intercooler with out the kit and get some custom work done?

any ideas how much to get it done in Perth?

thanks for the info.

and one more thing does this affects the hks type S intercooler kit???

if it does ill just get the intercooler by itself and get some custom piping done.

hehe didnt cross my mind dude sorry :(, so u dont think the air in the pipe will heat up due to amount flowing through

Put it this way.... You will not notice any loss of power whilst driving, as bubba said the velocity of air over the pipe is too fast to transfer any significant amount of heat. You will probably get more radiant heat from the engine itself!

If you are really that concerned get some heat wrap.

Ash.

yeh ill see how the heat wrap goes, or get bonnet raised a little, i am planning on getting it repainted and realigned so might as well do it all at the same time :action-smiley-069: be very interesting to see how cold the air actually is though compared to piping temp

i do custom piping and agree that inlet and outlet on the same side of the cooler is soo much simpler and shorter and doesnt require messing with the battery or washer reservoir . only problem is that the front bar mounting point may need to be modified depending on the cooler .

battery is in boot and washer bottle isnt affected

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
