Intercooling
« on: December 21, 2012, 12:16:25 pm »
Hi there all
Been doing a bit of research into intercooling my 1.9TDi engine...
now normally i'd just go for a huge FMIC and stick it infront of the radiator
The trouble is that the engine is now in the bed of the caddy, and doing that would lead to a boost system about 5 metres long, which as you can imagine, not ideal...
So my other options seem to be:
-floor mounted air scoop in the underside with an intercooler mounted above that. may result in ending up with a high pressure bed area and reduced efficiency (assuming tailgate and bed cover are on)
-cheap ebay water to air intercooler of unknown quality, possibly welded into the intake manifold for a nice short simple boost piping. then stick the pump, reservoir and second radiator (v mount?) in the engine bay
-as above but using a 4x6 barrel intercooler mounted inline
-get some Laminova water to air intercooling 'bars' and integrate into a DIY intake manifold

Just curious as to what the thoughts are on this forum.
would love to hear any advice on the subject

i've seen people piece together air to water intercoolers for pretty cheap, gotta be creative.  i think one guy used a ford probe or mazda oil cooler or something.  aren't air to water intercoolers more efficient as well?

Air-water. If you're doing it on the cheap you can re-purpose oil coolers or regular radiators for the cooling end up front. A decent pump is the Rule live bait well marine pump, about $40 new. Model 401 I think...
I used 5/8" garden hose (the red industrial type) for all my lines, w/ brass barbed fittings.

I have a U-shaped intercooler for sale, if you're interested PM me, I went with a straight-thu type instead.

never considered building an intercooler like that i must admit. they tend to go for fairly cheap on ebay anyway
There's a lot of argument about the efficiency, i suppose they will be if you can keep the water cool enough, they're also better at flowing the air from what i understand
ideally i'd like to get my hands on a pair of long but low radiators so i can run the 2 in v-mount up front, but will probably just end up being one infront of the other
i did consider ducting, but a bit bigger than that ;)

just come across this on ebay, http://www.ebay.co.uk/itm/LAND-ROVER-4-2-SUPERCHARGED-O-S-INLET-CHARGE-COOLER-2W93-9424-BH-E9531000-NEW-/251190765142?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item3a7c22e656 having a water to air welded into the intake manifold looks like a damn fine idea, boost piping would be nice and simple too.

cheers for the heads up on the pump, i'll see what i can find over here.
Using hose pipe sounds good too, although i'd probably want to get some nice stainless overbraid pipes in the future.
Can't imagine it'd be very economically viable to send it all the way over here, but thanks anyway!

A properly designed air to liquid intercooler will outperform an air to air system in every way.  Lower intake temps, better flow and reduced intake volume (faster spooling).  The downsides are higher cost, added complexity and more parts to fail.

glad to hear that, sounds fairly win-win then. only part really liable to fail would be the water pump surely?
As long as i have a temp gauge for the circuit(or post-IC charge temp?) i can make sure it's working properly anyway

you going to have a roll bar on your truck ?? if so why dont you make that your intercooler , discharge pas side inlet drivers side , you be able to put your hand out of the window and feel your inlet temp when 200horses are geting set down , how sweet would that be  ;)

Well, no.  While the pump is the most likely failure, you can also have a hose fail or most expensive would be to have the extra radiator leak.  You will also need to incorporate some accommodation for coolant expansion (e.g. tank) and that can also fail. 

All that said, I am in no way opposed to air/water installs and will likely go that route on my '79 rabbit.

probably not, i want to run a bed cover for a little discretion (apart from it's going to need an engine bump in it  :P) plus it'd be nice to have a bit of a 'boot' left to put cr4p in.
It's a nice thought though! I wonder what kind of cooling standard pipework does... as i'll have the pipework for both radiators running up the underside of the tunnel.
hmm true, but at least it wouldn't be fatal for this system to go down (would just run worse). rather that than main radiator or water pump fall apart!
will definitely have a tank, any extra weight over the front will be a bonus, as odd as it sounds i'm very worried about understeer
That's good to know that there are others too, have seen quite a few running W2A intercooling
Anyone UK-based that could recommend me good/cheap radiators?
I'm a long way off doing any of this yet but the more i can get planned ahead the better
Still struggling with M-TDi setup :(

landrover pump one noch forward (clock wise) on std 1z fixed pully on the pump pully , and the rest of engine  TDC no1 and you should be able to fire her up and fine tune from there ,
how about a SS roof rack intercooler ,man that wood be sick  :P

you don't realise how little i know what i'm doing  ???
i'm going to make another thread about setting up the engine/pump to keep things tidy
And i'm not scene enough for a roofrack  :P

my god....

that car is amazing..
