Intercooler piping

Ok there has been small discussions about this in the past but nothing really came from them.
What are peoples thoughts about the material to use for intercooler piping? Alloy or stainless?
Pros Cons?
Thanks

thermo wrapped aluminium is da bomb. Or thermo wrapped titanium if you can afford it.
I was quoted for a full pipes setup for Draven car - 3 inch piping for the cooler, all silicone hoses, $600. Entire kit weighs 580 grams
you'd prolly wanna wrap it though, cause it's thin walled aluminium so it'd get a bit of heat soak from the engine bay.

So alloy seems to be the trick? What wall thickness is recommended?

Mild steel with HPC coating is the way to go IMO, if you're not made of money that is. I did this on the poopra and it's extremely effective without costing an arm and a leg.

Isn't HPC coating pricey? If it's not, then I might have to go get it done! Stupid 7M and it's stupid cooler piping going over the block and turbo

It ain't cheap but you get what you pay for. If your inlet piping is going near hot things I especially recommend HPC coating! Aluminium alloy seems like a bad idea since it conducts heat even better than steel...

I got my intercooler piping bent up for $200 in 2" stainless 4 pieces of mandrel bent pipe... one hole in my chassis
Just ask around a bit... I found a lot of places didn't want to know about intercooler piping, until I talked AAA Exhausts into it

ment to add! joorsh titanium, mate get a life. tell me who on the planet is using titaniam mandrel bent intake on a car worth less than a million dollars. haha ived used sheets of titanium for undertrays but titanium is very hard to weld and expensive to weld. it needs a closed enviroment to do it. a set of titanium rods are around the $5000 mark and they are forged with a machine can you imagine the cost of doing you piping with it!
i can get titanium mufflers for $800 so intercooler pluming would cost arount the $5-7k mark. i suppose if your going to dream, dream big!lol

Yes, anyone who doesn't use uber-expensive materials like they do in F1 is obviously a 16 year old kid who knows nothing about cars.
For those of us who live in the real world, mild steel works fine. Sure it's heavier, but we're talking 1-2kg here; I'd rather spend the extra money elsewhere.

I run aluminium pipe work (not coated) on my car from filter to turbo to cooler to throttle body (so the whole lot).
Just about got another car back together which is essentially the same as mine but with all mild steel pipe work (used due to cost and ease of manufacture in the garage at home). Once it's running I will do some comparisons in air temps at various points along the inlet tract.
You can't beat the bling value of some polished aluminium pipes though
I doubt most people on here would notice gains/losses either way using one material or another. I think the cost and ease of fabrication usually establishes what most people go with.
I know sweet FA about the technicalities of anything, I just know about things I have tried, and will only comment as such.
I do enjoy reading these posts though when good info is forthcoming.
Cheers.
I hope this stays informative and doesn't degrade into trash talk.

Agreed Norbie!
I used stainless because it was easier, and cheaper for the exhaust shop, and thus cheaper for me. They couldn't paint it in house. They did give the outside a coat of paint though, which made the whole setup much sexier. They even lipped all the pipes!
kingmick, I don't need alloy intercooler piping... i'm not after a dyno queen, I think the money I saved will be better put to use getting my ARC intercooler cleaned up (thanks bbaacchhyy! i cant wait to try it out...)

norbie alloy isnt expenssive anymore. a 90deg 2.5 inch is about 35 dollars which is the same as most people used to pay for stainless. lol they have been using it for 20 years so its bound to get cheaper:)

The reality is that alloy is good for bling as it can be polished and can be lighter than S/S and mild steel.
As for heat conductance.
Think about heatsoak under your bonnet for a moment and after about 10 minutes driving, it won't matter a zack. Don't belive me ? get the car running for a bit and then climb in under the hood and close it and see what it feels like
Just because someone used it on a 100000 hp car doesn't mean anything.
The two points above that I have hightlighted, and Norbs last comment sum it up basically.
Go with what you can afford and what you like the look of.
I defy anyone to prove, that in the REAL world, the gains for the AVERAGE car (like most here) will not notice the difference.
Q.E.D.
Personally, mine is a mixture of S/S, Mild steel and connectors. Why ? 'Cos that is how it came, I'm adding in some mandrel S/S bends (cos the supplier that I go to doesn't do mild steel and I don't need bling) to adapt it from fitting a MZ20 to MA61.

well said ke382tg!well said. the only plus side of alloy is that its much cheaper now and ir weighs less and workes better!for day to day you prob wont notice a diffrence but track days like sprints or full field you will. the little diffrences add up, but to do it the cheapest it possable can you would go exhaust pipe etc and there would be little to gain but you also have to think of rust inside the pipe going into the engine etc. if i had a limited budget and skill i would go, steam pipe turbo manifold and exhaust pipe inlet plumbing. for day to day it will work well but you miss out on the horsepower gains. horsepower gains once you hit a point with an engine cost a huge amount of money to get 10 or 20 hp. the question was what is best for the job etc and alloy is affordable now, its taken 20 years to get to this point but now its the go.

My alter ego is a bit geeky, it knows a bit about overclocking and materials used for heatsinks...
Aluminium is used because it is a great conductor of heat... and it can disperse heat into the air really well too. Steel however isn't good at all... it's terrible in fact.
For short runs, perhaps on a dyno or on the drag strip, aluminium would probably be alright since it kinda suites the scenario. Stainless however would be better in the hills where you are always changing speeds, and not always getting good airflow under the bonnet to help remove heat... but thats why we use intercoolers, which see much higher airflow.
I'll take a gamble and say stainless pipe work, aluminium intercooler.

bbaacchhyy not meaning to be rude but im guessing 18 and on your first car! to put what you said into the real world of cars and not text booking!a race car when it finishes a race it does a cool down lap! when you a racing or driving hard on the street everything gets hot ,but the under bonnet still has air flowing through it. so on the slower part of you street driving or racing the under bonnet temps lower. and the lighter something is the qicker it cools. things that heat soak are heavy like cast iron and billet steel and they take longer to come up to temp but take longer to cool. a little material heats quicker but also cools alot quicker so when you are going slower which is most of the time as even a race car goin flat strap around the track only has full throttle for about 35% of the whole lap or there abouts there is cool air rushing past the piping! how many stainless steel or steel radiator or intercoolers have you seen? theres a good reason for that. im just glad its this way otherwise my rolla would be 4 ton with lead intercooler etc.

I stand by my previous logic... stainless or even mild pipe work, aluminium cooler.

good thoughts HyDrA but its the same dyno,drag,circuit or hills(im not much into dyno or drags)but its all the same!on a hill you are using max load with lower speed ! so it is even more crucial that you use a material that gets rid of its heat quicker, so the lttle air that does cool it works as well as possable. my cooler core are acid dipped to an inch of there life so they can take 65 psi of pressure(no i dont use 650psi but it gives a saftey margin) and are as light and have a big surface area(hence why they are never straight up and down, even in my road cars)
!lmao like a skiny girl and a fat one. you can hammer away at a skinny girl and she will be ready before the next round, but a fat girl will need to get her breath back!sorry made me laugh

Oh dear. Can't be bothered separating out the issues here so I'll reply in one.
No. 36 and at least 3 cars and 4 motorbikes (not a huge amount, but still, none were std.) Airframe fitter by trade, Ass Dip in Aerospace Engineering, BTech in Mechanical & Manufacturing Engineering, Grad Dip in Manufacturing Management, employed as Senior Manufacturing Engineer at GMH.
So what about a cool down lap ?
Yes, the lighter something is the quicker it cools, but the rate depends on the material, shape, environment, temperature differential, and thermal characteristics of the surrounding environment.
Been racing, and I was at FT more than 35% of the time. Try about 70 to 80%. 13B J Port RX2 Improved production race car.
At no point did I say that steel should be used for cooling such as a radiator etc.
I merely pointed out that for the AVERAGE car in the real world, the difference would be minimal. No where did I say that alloy was no good. Due to the higher thermal loads in racing, once the air gets past the radiator/IC/oil cooler it is HOT !! The reason for radiators etc. Hence the heat in the engine bay is lots. No cool air in there !!! Don't beleive, as I said before, climb under the bonnet and see. Or if that is too hard, just stick a thermocouple under there
Sigh. Thats enough for now.
Oh, and next time, use punctuation to make it easier to read. Please.

if you race IP then you must use carbie or dont have data logging, because i would bet a national car against yours that you could never ever race a circuit unless its oval at 70% unless you are way under powered for handling. god if we use 2 litres per km at most tracks at 70% WOT we would use 5+ litre per km! as i said no offence ment. a rotary uses a bit more WOT because power comes on later than noraml engine but no were near 70% unless its a standard engine in a good handling IP car. 70% would mean in a full feild race of 5 laps you would use close to 50 liters. instead of 25-30 in a rotary.
SORRY about the punctuation and typos i type as quick as i can with my two fingers and no i dont have 6 on each hand!and i cant be bothered speel checking or looking at grammar

Hey Bbaacchhy, did I ever piss myself when I read the 16yr old kid comment. kingmick hacked into me something like a year ago when I was new to the forum and described me as a pimply faced kid crying because I nearly crashed my car and said he was going to beat me up. Now at least there are some people on the forum who have met me and know how absurd this is.
Mick my good man, I don't doubt that you have some experience in some of these area's, but dude, get some fucking social skills.

Mild steel is the best material for barbeque plates.
-disperses heat evenly, hard wearing generally non toxic
Stainless is shit for barbeque plates.
- poor conductor of heat needs massive burners to heat evenly without cold spots. harder wearing than mild steel but is heavier and some grades are toxic
Aluminium is also shithouse for barbeque plates.
- altho the best dispersion of heat for even cooking also has downsides of very soft so plastic utensils should be used to avoid shavings in your sausages and has also been linked to alzheimers disease.
in the end stop arguing like biatches over small things and think about your sausages

Holy shit this thread took off
Norbie, you think stainless will achieve the same results as the mild steel once its HPC? For me stainless is more convenient than mild steel because I don't have to get it coated right and not worry about it rusting, plus I can get access to stainless cheap.

Shane, The results after HPC should be virtually identical. I'm not getting mine HPC'd yet, as I have spent too much already , but will probably get done later.

Intercooler piping doesn't need any real strength and corrosion won't be an issue, so go with thin-walled stuff to save weight.

IN seriousness, I find this thread quite interesting... I am doing my cooler piping soon and am considering mild steel.. my main reason for choosing this is cost.. and the main reason I may decide against it is that I dislike the idea of that powdery surface rust you see on exhausts entering my engine!

1. That's why you HPC your pipes.
2. Even if you don't, the inside of your pipes will quickly be coated in a thin layer of oil, which means no rust.

If you are feeling cheap and just want it to it do it's job, then this is what I did.
Got some mild steel pipes made, included 3 pipes, AFM -> turbo, turbo -> IC, IC -> TB. Also included welding a BOV on to one, and installation for $170.
I then wandered down to Clark Rubber and for $20 got some heat reflective rubber stuff and zip tied it one. It makes a noticeable difference, especially in my engine bay where the pipes where getting bloody hot to touch, and now are near ambient temperature. It does depend a lot on your turbo, boost, IC etc... but yea, I found for $200 you couldn't complain.
