Oil cooler fans?

[mx1311]

you will see a lower oil pressure when the oil is warm due to the stock thermal pellet opening

i was thinking i might mount a fan somewhere down that way on one side (but not stuck right up on the cooler) to generally increase air circulation at standstill, since theres a bit of room with my setup, might reduce heatsoak. Should be able to tell if its doing any good when i get round to installing the faster temp sensor thingie.

had a bit of an experiment today, took out the bumper indicator (wasn\'t plugged in anyway) and made a grille, then stuck a fan in utilising a quick alu bracket and the existing front splitter bolts - and made some ducting channelling the air out the grille. I wired it via a fuse to a spare switch on the centre console, it works whether the ignition is on or off. It was a spare switch normally used for the fog lights. I do intend to put a timer circuit or maybe thermostat circuit in there someday. It blows a fair gale out the side, but havent been for a drive to see if it makes any difference to oil temps in traffic yet.
the fan is a 12v waterproof fan, low amps and good flow.

Well I managed to score myself a brand new slime line elecy fan from an aprilia motorcycle (one of the super bike ones not a 125!) cost me 20 notes deliverd! hope to have it on Tuesday, then it\'s just to fit it to the drivers cooler & away we go!
Shall report my findings as soon as I test it (which wont be long!) also show a step by step in my project post!

having run mine for the last week or so, i am quite pleased - just with one fan blowing out the side port, it manages to drop the oil temps by 10 degrees when i switch it on whilst cruising, when booting it it seems to drop it by about 5 degrees or so.

Where is your fan mounted Ash?? Is it the inside of the bumper by the mesh, or on to the oil cooler itself?

it stands about 5cm from the side of the bumper, sucking air across the back of the cooler, and ducted up to the mesh i made where the light was. I\'ve replaced the light unit on the other side with mesh too, but havent put a fan in yet.

[Jono FD3]

what did you use for the mesh matey as it looks alot better than those horid amber jobs!!

[ashc]

i made a quick mold of the original light in wood, and bent the mesh over it using a rubber hammer. If you leave a tab a couple of inches wide and perhaps three inches long on each long edge, you can fold it round the inside of the bumper (if you get what i mean!) and it stays there solidly without any other attachments. I expect youre well capable of making a mold but i could send you mine if you want?

Awsome matey... cheers for the info no worries about the mould Like you said LOL

how about something like these:
 
radicalrc.com ducted fans
eBay
 
i was thinking of building a shroud to go on the rear of my intercooler and sticking two or three of these on to suck air through.

think you would be better off with motorbike cooling fans as they are totaly weather proof!!

[ashc]

my fan is supposed to be wterproof, but i don\'t reckon the flow would be as good as a bike fan - can you post up some pics of your project jono?

will do matey!! hopeing to get this sorted the weekend all going well!! lots of pics & text will be posted somwhere

[Jono FD3]

Well, not quite as straight forward as I was hopeing and I still have to wire it up (hopefuly today!)
Anyway, here are some pics of what I used & how I fitted it!

The fan is a cooling fan of an aprilia superbike (not sure what one!) Basicaly I took a gamble on the size & for once I blagged it!! Here\'s a pic of the fan:


Next was to make the mounting brackets..... I opted for a through cooler mounting system. all you need is a few cable ties Spongey foam & some plastic!


Now you need to cut the zippy bits off a few ties to make the securing bits:


Now you need to strip the inner arch back so you can see the cooler (on which ever size ou want) I opted for the driverside on mine, so I had to unmount the header tank for the coolant system!


I also had to unbolt the lower mount for the oil cooler & take it out to allow me enough space to get the fan in!!

Now you need to feed the cable ties through the cooler fins (spongey bit between the fan & cooler on each mount point)


Now put the secureing zippy bits on the outer side/ (again foamy bit, then plastic, then zippy bit)


Pull them tight:


Now cut the excess off:



Hay presto, fan mounted... now wire it up & rebuild the inner wing
