lads thought id share my finally completed setup. it came to a standstill for a while there as i couldnt find a cooler that was of a decent size with an easily adaptable tank arrangement. i got a intercooler from a mate when he upgraded his WRXs cooler so for a carton of beer i got a fitting welded to it for a good fit. also fitted a fibreglass copy of a gu scoop. happy days

Cheers. Has anyone on here drove their patrol before and after fitting an intercooler? Just wondering as after fitting mine i havent noticed much power difference or egt changes. Im sure there would be an improvement but i cant really notice it. A bit disappointed

I am considering the same type of intercooler yet around the other way with the forrester type bonnet scoop.
I am thinking the intercoolers may work better with the little baby turbos that are being pushed to extremes and creating a lot of heat.
My egt's are low without one i have never seen 500 degrees pre turbo.

I wanted to fit mine across the motor too but with mine being hi mount i couldnt make it work.... mine will creep over 500 if im flogging its guts out on a hill but wont go over 550. But thats what it did before i fitted the cooler anyway. I was expecting a big improvement..

Those egts are post turbo.

Did you turn the fuel up and see what it does compared to no intercooler .
probably not a good idea if your already getting 500.
Makes me wonder if it is worth it myself .
do you have a decent scoop on the bonnet with the airflow sealed off around the intercooler.
My mate was saying just fitting a fan under his intercooler he noticed an improvement.

not yet. Thats my next thing to do. More fuel is more heat though ay. Dont want to push it too much more. But ill have a play and see

It is a small intercooler and being top mount would suffer a lot of heat soak. I thought that the wrx intercoolers were water to air and this would possibly explain the 2 blanking plates you have. If it is meant to be a water to air this would explain your egts not changing much.

Those blanking plates are just over the original air inlets. Its air to air still. Matbe sti's are water to air, never seen a subie water to air from factory but not too sure. I know its fairly small but i was expecting an obvious gain. Saying that its a fair bit than a standard td42 cooler

Had a look bloke and you are correct. My bad. I know with my Gu factory TD42Ti i have wound fuel and boost up and can push to 500 if i want to. I also notice if i get in and drive it from cold its good but if stop for fuel or anything the heat soaks into the intercooler and i can certainly notice the difference in power and intercooler efficiency.

Haha yeah i noticed that too. Have to keep moving.. well if youve wound yours up too and getting similar figures to me then it must just be the norm. Cheers for that! By the way, what economy you get? I get about 750km to 120litres

Yeah im getting rid of top mount in favour of a 600x300x75 front mount as its our general tow rig. My economy is slightly better than that i can about 650 ish out of about 90L. Yours works out to 16L/100 mine is about 13.5L/100.

It was the first mod that was done to my stock GU pre boost and EGT guage . fitted a changeover / welded core to end tanks PWR performance unit . massive difference , noticeable staight away , no more flat spot during accelleration . So much better . cheers

thats a fair difference hey, thats why i dont want to keep winding up the fuel, as i have noticed my economy turn to poo. i used to get over 1000km to 120l before i turboed it

No they are just air two inputs one output standard they have a y branch into the two inputs.

Yeah I havent seen my get to far over 15 per 100 and thats when im towing. What sort of boost are you running?
snowy

Running 13 psi at the moment. Im thinking about fitting a boost compensator to reduce a bit of over fuelling on takeoff. Not that its that bad.

I wouldn't worry about a compensator to much my GQ runs 14psi unintercooled and often returns figures around the 13.5 to 100 have you ever had the pump off the old girl?
snowy
3rd July 2012, 02:46 PM
Righto. I thought it would have improved economy with it. One thing ill definetly do soon is an injector service. Hopefully that might make a difference

They are really only for emissions you could probably utilize one a lot more efficiently if your chasing bulk hp cos you will need bulk fuel. I have basically tuned the compensator out of my gu pump as its makes it's so much nicer to drive between idle and 2000rpm. Diesels need heat to make boost and to make heat you need fuel a compensator doesn't allow fuel til you have boost so it's kinda working against itself.

Gotcha. Makes sense. I just figured if turbo models were fitted with it from factory then it must be beneficial. But obviously is to reduce emissions. Fuel is power and makes sense that if leaning it out down low will reduce power... i think a injector service and a dyno run will get the most out of it. Ive been playing with the fuel screw and watching my pyro but i guess its a very 'there abouts' tune
