slimline radiator fans

[wildturkey]

does any1 know where to buy these and how much?

I've looked at the ones on trademe and ...........although they call them slimline.............they are actually no slimmer than the factory ones on my radiator (65mm).

point me in the right direction?

[Guest]

didn't silverdale radiators do them?

and AAP used to get them. they got bought out, so dont know who they are now though

Ripco do a 10" fan that is around 45mm thick

do the slimline fans work as well as the factory fans, cause the slimlines will have no shroud on them?

i have had a one or two on other cars i have owned, i thought they worked better than the factory ones, most slimlines are highflow. im goin to put on on my wrx because i have to now.

Running 2x 10" fans on the coupe with no issues on the road or track

They have shrouds and flow mega air ( more than a factory ) due to twice a many blades and more powerful motor (draws another 3 amps )

The slimline ones do pull more air, but they also only pull it through the area on the radiator that is behind the fan.

The only way i would be confident in saying they help the radiator work better, is if you got the biggest diameter slimline fan you possibly could and stuck that on there, atleast you would be using more of the radiator.

This is what i did for my fan on the tight gap on the EZ30R:

Went to pick-a-part and got an Air Con radiator fan off a STi they had there, they are paper thin and have awesome steel shrouds on them.

I then got my slimline fan, which happened to be the same diameter as the fan in the shroud, and fitted it across. Then to make it fit perfectly and look factory, you just grind off the mounts on the shroud and weld them back onto where you want.

This will give you awesome flow while using more of the area in the radiator.

fans only needed during low vehicle speed, at which time the engine isnt making much heat anyway = usually idle / in traffic

early fans come on with full throttle also , but this was deleted in later models

Also if there isn't much of a gap between your radiator and engine. Having a small gap means it cant exhaust the hot air fast enough due to the lack of ventilation, which means all of the cool air ends up going around your radiator, not through it as you go faster (which usually means a hotter engine). Having fans going on the radiator in this situation will improve airflow even at high vehicle speeds as it is forcing it to exhaust hot air, which will allow for more fresh air to come through.

put fan on the front of radiator to give more room behind

Agreed, but i think it looks ugly. But thats just me been an arse ;D

[swee]

you can get SPAL fans from paul manuell, they're 52mm thick from 8-13" i think

i have a front mount cooler and theres plenty of room. thats actually one reason for doing it, will draw air through the intercooler as well when idling/town driving, been alot closer to it.

nice..........wana send me sum pics of ur setup?..........or post them up?

i can watch the oil temp rising in my car when i stop after a decent thrash, only started since putting the alooy rad in and having no room between engine and fans, thinking slimline fans give more room for heat to escape, and not as ricey as a vented bonnet!

would that not create turbulence when moving forward and slow down air flow through radiator?

maybe a little but i have had them setup like this on other cars with no problems. and i will be running a alloy radiator, plenty enough to keep it cool.

.

i would say the fan on the back would have a very similar effect though and slow the flow.

i would if it was finished lol, the front mount is all in, and bumper on, just no radiator yet as that will be custom to suit my plans for intercooler piping. car has been off the road for around 5 months now check the impreza garage if you wana see what im doing.

but basically there is the width of the bottom radiator support empty, i can measure if you like but its more than 45mm thats for sure. your legacy should be similar in space there.
