Cooler piping pattern?

[JH32]

I am thinking I might put my cooler in myself ... and a mate said that if I got some pipe and measurements his brother would bend and weld it for me.

Does anyone have a pattern or picture or measurements of the piping that I would need to fit a cooler to my R32? The end tanks are on either side so go in one side and go out the other, not entry/exit on the same side.

Cheers

Any exhaust shop should be able to sell you 90 and 45 mandrel bend pipe in whatever diameter you require.

................no bending james, mandrels

remember least amount of bends as possible

hot out of the turbo passed the radiator cooled charge up the passenger side.......

non rusting pipe

Ive been browsing Japanese catalogues in the past few days looking at kits. Most have diagrams to show you what you get with the kit. Most of them for the RB20DET have a length of pipe running along the bottom of the core back to the standard piping. This seems like not only the shortest route, but the easiest too.

If you see this years Blitz catalogue, it has a half page size diagram of it, should give you a clear idea of how to pipe it.

Only problem with teh under return is loosing some core exposure trying to keep teh pipe off teh tarmac but James's bar might be ideal..... also returning that way makes a cold air box a lil more difficult but,,,,, you do avoid bay soak alot more

[JH32]

Steve ..... so I would want the pipe from the turbo to go into the left hand side of the cooler (if looking at the car from the front), go through the cooler, and then out the right hand side. Then up and over the top of the engine?

edit: here's a little pic

cheers mate

[MrMayhem]

that teh over rad style

If you go red's suggestion it might be a better way with such a low lip....

keep teh majority of the pipe outta the warm bay for teh longest time

[meggala]

mine is like that

here

[MrMayhem]

its teh better way if you dont loose surface exposure due to having to lift teh cooler up to avoid the return pipe exposing itself

[rev210]

keep the pipe from the ic back to the plenum as short as possible , that means you have to buy an aftermarket plenum (joke). The hot pipe (turbo to ic) should be thermal wrapped and again as short as possible. Don't worry about trying to cool of intercooler pipes or anything, they don't tranfer heat efficiently, that is the intercoolers job. Keep them from getting hot in the first place or if they are hot ,like the turbo to ic one, trap the heat in the pipe for extra gas velocity and reduce any radiated heat.

remember : the shortest pipes possible, the ic to plenum ought to be the shortest if you have to make a choice.

Yeah Mayhem ive got a GTR front bar so hopefully when my time comes for the FMIC ill have enough height on the gaping hole in the front so that the pipe can run under the core without too much exposure.

I was going to try running the pipe along the top of the core inside the bumper, but unfortunately ive got N1 slots on it which would have to be hacked up in order to fit a pipe behind them.

PS: Mayhem, mate of mine tells me hes got a deposit on a VH41DE youve got? Whadda donk!

[MrMayhem]

I had a trust fmic return under itself but cos of my bar u lost about 50mm off core exposure.... so i chopped it into a cross flow with a custom plenum

removeing 1.4m of useless pipe

Yes teh lil VH41 should be a excellent install

VH V8s are a untapped source of serious horse

might be a trend about to start

[JH32]

So after reading all this ... and then referring back to my picture ... if I routed the red pipe underneath the cooler, or even above if it would fit, could I then have the blue pipe coming out like that?

That way, I could fit it in the same positions as the stock pipes go as Meggala said, and also the return pipe would be shortest, as rev said.

Cheers heaps for the help everyone!

[JH32]

btw: how many metres of pipe would I need to buy to do this?

And who in Perth can bend 2.5" stainless pipes?

I can get the piping cheap ... how much would it cost to bend it?

Thanks!!

[red17]

Dont bend it, construct it out of straight pieces and pre bent mandrel bends which can be bought separately at various angles. It'll cost more but the finish is much nicer and I believe someone wrote extensively another thread about why press bends should not be used on intercoolers, efficency wise.

Yes you can run the blue pipe as is, just use all of the stock pipes up to the front bumper, then add to it with some nice stainless bitz. I believe thats what meggala's pic shows.

As for cost, i have no idea. But let us know, coz im thinking of doing the same soon

[JH32]

Yeah ok mate no worries!

I'm now thinking what you said ... might use the stock pipes down till round the front bar when i can add in some aftermarket pipes.

Cheaper solution me thinks
