Good Cooling Fans

[neal1980]

Hi,

I currently have some slim 12v SPAL fans and they were the highest CFM I could find at the time but there still not great at bringing the temperature down (will have to try and dig out the full spec)

I can see AXIAL fans which are 5 blade and seem to have much more cooling, worth changing??

Or can anyone point me in the direction of some powerful fans from another vehicle which would be suitable.

Thanks

Neal

Sorry should of put more details was a rush post on my phone.

Its got 2 spal Suction fans on an alloy rad (biggest I could get in) there is a 4" thick intercooler in front of the rad and basically zero space anywhere. Will get some pics later.

The temp just keeps creeping up when stationery, car is not on the road yet. I am just starting it and getting it to idle.

Its only just off keeping under control but I need reduction in temp. My thought were more poweful fans to compensate for the intercooler in place or re-do the front with a charge-cooler setup to allow space for the rad (major change and £££)

Oh and the temp climbs up and up slowly over 100 to the above poster who is clearly having a bad day

I see lots of gaps between the rad and the nose, seal them up.

Would this make much difference when the car is stationery ??

Me having a bad day? If you class me as having a bad day due to my asking the obvious, I have wasted my time trying to be of help and yet I do hope you solve the problem, it now looks a complicated task that you are facing and the above poster that mentioned shrouds and other fixes has definitely given the issue some thought and pointed you in the right direction

I like the look of your car. What are those 2 green things?

Cheers almost complete after 3 years!!

Space is tight as you can see...Green things are the air filters for the turbos - again not an ideal place but with the intercooler they are fine.

Maybe Im not seeing things correctly here but shrouds and sealing for the front will only help when Im moving ??

When im stationery im only relying on the fans to cool - so the power of the fans or the way there mounted (with the 4" intercooler im surely restricting them pulling in fresh air) hence my idea of more powerful ones or losing the intercooler and going chargecooler as an absolute last resort.

Hi Steve,

No I dumped the TVR gauges years ago, got a capillary one direct in the waterpump. Going to check some temps tonight with an infrared thermometer.

Its very slow to climb but just keeps climbing to over a hundred then I shut it down. There is a small gap between intercooler and rad which I can seal up tonight and try again.

Question time.

What stat is fitted ?

Are the fans placed so as to cover as much as the core as possible...ie staggered if need be ?

Ducting/shrouding is always sensible to ensure only cold air gets drawn through the core, and no hot air is re-circulated.

I see some lines, and what looks like it may be a remote header tank ? Layout looks a little confusing ?

Hi Steve,

This is the engine with your forged crank and rods in

It has an LS3 pump with a 71 degree Stat from summit. 2 X Spal Fans mounted directly to an Aluminium Griffin Rad. It has a remote header tank (also a cap on the rad which is not used)

I used this diagram for the design.




Does it matter on top and bottom hose configuration they appear to be the other way around on my radiator.
