FAQ: Can I use PVC pipe for intercooler piping


Recommended Posts

wen i smashed my r33 gtst ( 2002) i had sum pvc piping in the garage and thought wat the hell why not.(standard cooler) quick fix until i could buy replacement parts. front end was fixed except for the pvc piping because its been on for 6months and not a sign of trouble. car was thrashed hard everyday.

all said and done i dont think pvc is better than steel ( strenght - heat - crack resistent ) a small investment for peace of mind.

imo.

i used to have a pvc pipe connected to the pod filter in my cough cough excel, I sprayed it with this heat resistant black paint stuff, not sure if the paint did anything but it never melted or warped or anything.

but the excel wouldnt have enough power to generate enough heat to melt it :(

hey guys i know this is an old thread but when i saw it, it made me think why not. i work as a PVC/ABS machine operator we make all types and sizes of pvc pipes here in melbourne. as i can get my hands on anything i want i might as well give this a try.

we test 1 out of every 100 pvc pipes made b4 they go out in the yard to be sent off. they will hold pressure up to 30bar(441psi) for 1.2hours (depends on wall thickness and size)

and i see this as no problems 4 pvc to hold vacume and boost pressure of say 30psi. as for the heat on the turbo side i would use thick walled pvc pipe on that side only. as it only takes about 2-5mins on 180Degrees for pvc to start to soften in a oven.

so i would use thermo warping around the turbo side to stop it from Direct heat. but u will Notice as soon as pvc is Exposed to direct air or anything under 180Degrees it will Harden right away.

dont Underestimate the strenght of pvc. and remember that all PVC has a 20year Warranty/Guarantee of any burst/rupture or Impacted Failure. if it has failed call up the Manufacture where the pipe has been made and they will replace it with no questions asked...

PS- if ur plaining of doin this make sure u only use pressure pipe only coz there is lots of crap out there like Stormwater pipe lol

with this information no is Responsible for any damage but yourself. so do it at ur own risk and post up on here wat u f.u.c.k.e.d up hehe :laugh:

Dont underestimate pvc

i made a 60mm spud gun/cannon that (bullet made from 2x18mm mdf cut outs from a 60mm holesaw held 2gether with 10mm bolt) went straight through my lunch room door (18mm mdf double laminated) from 30m away and through the back wall (further 5-6m away) into the store room and found a further 10m away!

made a few hundred shots since then, still strong as hell!

but for cooler piping, alloy painted black in MY r33 is strong and looks standard keeps the bacon boys away! and when u think about it its not that much more expensive and u dont have to worry about cracking, melting ect.....

I ended up using a small peice of pvc pipe to temporarily join 2 air hoses between IAC(I think?) and the cooler piping, and suprise suprise it melted

I totally forgot about it and didnt replace it with metal, on a full track day it only lasted a few hours before the thing melted and warped.

DON'T USE PVC PIPE its ghetto and wont hold.

Edited by midnight

Have a mate who used to own a R31 GTS Import RB20DET, had a heap of big truck stainless bullbars. cut them up and used the straights and the bends etc, few silicon hoses and wallah@ intercooler piping.

Worked a treat, never had a problem for about 8 months he had it on there. car has since been sold and im aware its still on there, and it looks the part.

vote for most full of shit thread ever !!

ps my username is "gts-4 dreamer" hack on that username, as im to lazy to log out of the misses username and login to mine, ask on that username if you need to, its all good

ps..

this thread isnt even funny its so stoopid... but hopfully the members section larfs ard eh !!!

I have had PVC pipes on my Soarer for over 7 years and have done track days and 1/4miles as well it’s my daily driver.

At first I had the white plumbing PVC but after a year of heat it started to suck inn on its self under vacuum, after really long runs, but never popped, or melted to the point of something going wrong.

Then I put some orange Telstra piping found at the rubbish tip. And has been good for six years on 12psi 297, rwHP.

Also you must use pressure bends, pressure PVC glue and must put a steel ring where ever you put a hose clamp, or it will go loose when it gets hot.

Back in the day a mate of mine did the exact same thing on his MR lancer when he turboed it (he just couldnt wait and was dying to hear the flutter sound). Anyway it worked...from memory it lasted about a hour or so before it melted. He was running about 10-12psi wwith his T3.

Ha ha ha, I've done the old PVC, but for a different reason..

We were stuffing around with different plenums and turbo positions, and so the cooler pipes had to be moved around alot.

I got sick of rewelding pipes so, PVC it was.

The car made 365hp and the PVC worked well. It was only ever a short term 'fix' so we could try a few different things and route the piping a few different ways. The owner of the car is a plumber, he thought it was very funny, even though he suggested it! The heat did get to the pipe on high boost, so he braized together a copper pipe cooler setup until he got some alloy pipes made. He sent the PVC pipe 'kit' to some place in melbourne i think, who coppied the design and made the alloy pipes. The best thing, we didn't pay freight twice. they binned the PVC cooler pipes and sent the new pipes back!

If you can keep the heat away from the pipe, and not get to much compressor temp, the humble PVC works well.

    • Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve. 
    • I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.
    • No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.
    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
    • Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.
