9" or 10" radiator fans

Other than the kenlowe ones are there any cheap ones that pump a lot of air?

Plenty on eBay but I don't know what one to get. It needs to pull air through an intercooler and a polo radiator.

I used one off ebay 12" i think curved blade which make less noise than straight and order push or pull depending which side your mounting also you could use a 24v one permenantly on it will just run at half speed to keep air flowing.

What size is a Polo fan??

jon200 - 16/1/13 at 08:24 PM

I don't know what size they are but I need something that's quite shallow. Do curved ones push more air?

Ford diesel fans shift a great deal of air - Eg Escort

Jon, the best advice I received was to ditch my Ebay cheapies and buy a Pacet Thinline fan. The difference is phenomenal and worth every penny. Fans are more efficient when pulling so if there is room on the engine side of the rad that will give the best results so I have read. In practice, I have not noticed any difference whichever side the fan is mounted.

Here is their link:

I have also heard very good reports on Spal Fans who I believe supply major manufactures.

If you are not convinced and definitely would like a cheapy, look no further. I have a selection

Cheers

Hi John, thanks for that. It will be fitted to pull through the radiator. What cheapy fans do you have?

+1, I could also be interested. I was planning on running 2 fans (1 push, 1 Pull) 1 set to the thermostat and 1 swithable, is this of any benefit?

I wouldn't put two fans on in that layout. Chances are you could reduce the flow.

Some OEM fans (I have a golf one) are two speed and have a twin switch, fan comes on slow at a certain temp, then full on when properly hot.
And do not underestimate the importance of shrouding the fan, makes a huge difference.

BTW a fan becomes pointless once on the move as the air is being pushed through anyway. The whole point of the leccy one is that it only comes on when needed.

I will have it from either the ecu to come on at 95 or on a switch in the cockpit for when on track. I am concerned that I will have cooling issues on track when it's finished.

When you say ducted you mean the nose to the rad/intercooler or a cowling for the fan?

When you are driving on the track the fan should not need to run, if it does the engine is undercooled or you have the wrong stat or fan switch combination fitted. When you are moving the forward motion will put more air through the rad than a fan ever could. Mine has a 88 degree stat fitted and a 95 degree fan switch. When I did hillclimbs and track days the water temp never got above 92 degrees but I generally switched the fan on manually (overide switch) as I slowed down and entered the paddock.

The intercooler is 3" thick so will block a fair bit of air, that's why I'm concerned. I'd like to be safe just incase.

the fan still wont make any difference once your driving unless its very slow driving.
main thing is to make sure you duct all the air through the intercooler/rad.
