People had asked me about the PVC intercooler pipes and if I was serious or joking.

I was not joking. I just finished the turbo-to-intercooler pvc pipe.

I have tested it one time, and it seems to work excellent. No problems thus far.

I'm going to have it painted or powder coated silver metallic. Nobody will know it's pvc...

The big thing here to note is that instead of a sharp 90 bend coming out of the turbo, there's a very gradual bend.... (less pressure drop).

mu ha ha

Ummm, no. It looks like it needs a Viagra.

What are the Habritrail tubes for? Crankcase venting?

 

You can forget about powder coating.

PVC aint gona hold up to a 400 deg. cure oven!

Paint in you only option, polyurethane.

When the boost hits... it's practically a shot in the arm of Viagra! :-)


And yes the plumbing is for the air/oil seperator.

When you say "tested" have you run it on the track at all? Or for an extended period of time under moderate to high boost? Just curious to see how well PVC in that application holds up under high temp conditions.

Pretty cool idea. See if you can make an oil filter out of a Campbell's soup can next!!

Seriously, if that works out that's a pretty good cost effective solution.

 

I'm not a materials science major but I think that PVC is too brittle and would have a tendency for failure by cracking and or delaminating. I am not sure what it can tolerate with regards to repeated heat cycles and micro/macromotion at the interfaces. I guess the price would be low enough to allow for frequent routine replacement, and showering the intake with small fragments of plastic is preferrable to metal shards if failure was achieved. I would lean more towards the composite material now used for intake manifolds instead.

 

What Tony has there is CPVC gray. I have seen it installed on pool heaters with 180 degree supply temps. It Should hold up fine.

 

jimbo - you beat me to it. Yes schedule 40 and 80 pvc can be brittle but cpvc is somewhat flexibly and definitely more heat resistant. We use it in industrial water treatment for higher temp apps.

 

I like your imagination and innovation Tony.

Keep it up!

 

Great idea!

CPCV has a rated service temp is 210F, softening temp is 295F and it becomes Viscous at 375F. Max temp of the turbo air discharge should be around 250F. The price is so low it could be replaced for PM.

It looks gay. Kudos Tony. Nice innovation...

 

Hey..

Yes it's CPVC. I've only run it on the street thus far as I just finished it today... and it started raining.

But once the rain stops, I intend to give it the full street test.... which should heat it up real good.

Also, I'm going to have fabricated up a cone shaped tool that I can press into the heated CPVC to flare the end such that a transition will be formed to to go from the standard size of the pipe to that of the throttle body.

Sort of a mandrel.... but not really.

I'm going to make the throttle body to intercooler pipe with this new tool once it's finished.

The nipples for the BOV are a simple solution as well since you can drill the correct size hole, then glue in the nipple with the correct cleaner/primer/glue, etc...

After that's it's the MAF manifold that will get replaced with PVC.

So... we'll see how it does on the track. But what I'm really interested in is the gradual bends (reduced pressure drop) of the PVC with no internal seams or misalignments caused by welding two pieces of pipe together (which screws up the air flow).

This is all the prelude to the plumbing that I will doing for the new dual intercooler setup. I just thought I'd start playing with it now... plus since I recommended it other Rennlist members... I thought I'd put my money where my mouth is :-)

How about an intercooler that incorporates a water injection function?

 

Where are you picking up the pressure for the wastegate?
