aaz intercooler pipe route? ?

Post by rgeneration »

hi all. right i know this is allot to ask and yes it is easier to click off this topic but i was kind a hoping someone would be able to help/advise me on position and routing of the charge pipes in relatively crowded aaz t3 engine bay? its a small 18"long 10"tall 3 inch deep cooler with 2" charge pips. im guessing ill have to pipe around engine to the right but honestly i just dont know, and my air cleaner uses the left hand snorkel at present but will take advice on moving that, maybe a photo or yours if poss? any info welcome . . . . thanks

ant.

Hi there, yes I know what you mean. I have seen the crowdedness of my aaz engine bay also and wondering where to put an intercooler which has been recommended several times.
my inlet/filter also uses the left hand cluster hole...

The key is to minimise length of pipe to/from an intercooler to reduce turbo lag, so what would probably be best would be to put the air filterbox behind the right hand cluster (inlet piping a bit longer) and go for an intercooler behind left one (shorter run then). I've not got round to this on my aaz yet as I just want it running first and will make improvements later. One slight hitch with this setup is the filterbox (JX - cylinder type) is a bit long and the outlet kind of gets in the way of the battery tray (if you have one back there, some have them behind the seat up front) so could just extend that battery tray 1-2"?

I'm in the process of doing this with a TDI install (1Z) to my '82 van - have just tie-corded the snorkel into the right hand air duct, flexi pipe down to airbox behind r/h cluster, then flexipipe thru MAF sensor on rear wall, more pipe across the rear crossmember to turbo inlet then intercooler slotted in behind l/h cluster. The tray that is the 'floor' in the l/h cluster space has to be cut and bent to make a place for the air to go - out the bottom, ideally with some kind of scoop at the air duct inlet also, even better would be a temperature operated fan (computer fans around 8-10") to push air through.

The Intercooler I got was from a SAAB - it has the inlet/outlet on the same side which is handy. Also a lot of pics/chat on this from the TDI forum (http://www.onelist.com/community/TDI-conversion" onclick="window.open(this.href);return false;) I have some pics on there, not sure how recent mind - easier to get my new AAZ running in the short term :wink:

Failing that option, could be as you say to go routing the other side of the engine where there appears to be a smidge more room but to get any real kind of cooling benefit, would need to have a cowling and fan pushing air through the intercooler and also some routing to take the hot air out of the engine bay (that will be like an oven). I don't like the sound of that mind, open to ideas though.
