I see you have put the dump valve before the cooler, any reason why??

He did the same on my car, works great as far as I can tell
Makes sense if you think about it, it is there to protect the turbo, something about back pressure or something, so closer to the turbo it should be more efficient, why dump the air after it has been cooled by the IC?
Well thats how I figure it anyway, but I think Calibrator should rather explain this tho.

I just fitted my new intercooler kit and I put the dump valve before the cooler. It would be nice to hear what The Calibrator thinks as he used to fit them after the cooler.

I read it best for turbo reliability (before cooler). Mine is after cooler, it dumps and you can still hear pigeons.
For response its the other way around... but that piping is so short it wouldn't matter.

The theory is that you are dumping hot air not air that has been cooled. I particularly did it on the land cruiser because that is a charge cooler and I need it to be as cool as possible.

By putting the DV before the IC, instead of dumping cooler air into the engine bay, you'd be dumping crap-hot air into the engine bay, near the turbo and air-intake area. I don't think the IC has to "work" to cool air down, so you're not loosing out by dumping air that it's cooled. Makes for a cooler engine bay, I'd think.

its not that much air, so it wouldn't really affect it...
I've done quite a bit of reading on this, the most popular reason why people install the DV on the hot pipe is S13/S14/S15 is that its easy to install there and there is space, also the hot pipe is metal instead of plastic / rubber
Then another thing guys mentioned was, for drag racing, they install it before the cooler, for circuit / track after or keep it closed.
Most manufacturers say as close to the TB as possible but before any air temp / any injection device (Think I read that from Turbosmart).
I don't think there is a right/wrong way, it works either way

Well by dumping it before the cooler you give the cooler that second to cool down with out any hot air flowing through it.

That Cruiser is heavy... would like to see it smoking up the tyres.... trying to catch the SX

Do you think the hot air from the BOV is hotter that the air around the turbo? There is so much air flowing through the engine bay at speed its not going going to make a measureable difference.
AS for intercoolers "working" evry atom that passes through it contributes to heating it up. This was discussed some time ago and I said the same thing I am saying now" I doubt it will make any difference to a street car"
Charge coolers are a different kettle of fish there is 6l of water getting heated up and it has to be cooled again so if I can save 2deg by venting hot air I am happy to do so.
That cruiser smokes all 4 wheels into 2nd gear. Pulls from 120 past 160 and accelerating in 5th up krugersdorp hill.
It smokes Honda Vtecs, Polo TDi's and Chrysler Crossfires and I mean SMOKES.
A stock S14 may put up a show but I suspect that a stock S13 will be toast.
Like I said be warned

So in what area do we find this toaster

Wow, what a sleeper, I'd probably go home and cry if I got smoked by a land cruiser

Looks like all this chop can do is throw around insults, dont you have homework to do?
