Intercooler fan yes or no ?

[Hodge]

so the fan is only to get the IC temps down not EGTs, what would this translate to.
sitting in traffic what advantage would you acheive, Im lost with all this.
struggling to see where the advantage is. Its not going to be performance
cause your only crawling, just something else to fail imo,,lol

just saying lol

Erm IC temps inhibit egt temps ... So the lower the intake temps the better your egts are ... So yes there is benefit .

Naturally if your IC is cooler then so is the air inside it.
If you are just crawling along there will be SFA air flow to the cooler which sits on top of the motor and gets hot.
Pretty simple really!

I always thought boost kept your egt's down ,has anyone done a before and after fan install
or just assuming if fan is fitted the intake temps will be down in a hot engine bay.
Just not convinced fitting a fan gives you bang for buck results, lol

Well it does but where does this hot charged air go through before it gets to the motor? That's right the intercooler.

So naturally the more efficiently the intercooler brings the charged air (Boost) down before it enters the motor, the better.

Just to put the cat amongst the pigeons- our radiators run a fan to pull max air for cooling at all speeds so why would a fan on an intercooler be different? Even at highway speeds, I doubt the standard scoop would collect the max air that could be pushed through, so a fan should help as long as it has correct pitch. A variable pitch as on aeroplanes would be ideal but at what cost?
I remember my mother used to have a cheap chinese cooling fan that made a lot of noise and spun quickly at max speed but hardly moved any air because of shape of the blades.

Top bullbar mounted spotties or light bars wouldn't help bonnet windflow either at high speeds I would think.

even by fitting a bullbar you have compromised the aerodynamics
Who has high egts @ low speeds ???

Here's some of the boys testing their EGT's @ low speeds :-)

Hypothetical ( and maybe stupid ) question ...... instead of installing a fan on the IC, if one was to fit a motorized damper-vane on one of the AC vents, and then directed that conditioned air at the IC, would it have a measurable effect or improvement? I read somewhere that a similar experiment was done using a CO2 fire extinguisher and that they found that it was too cold and it hindered the performance.

Have you ever crawled up a very steep long hill in the high country or somewhere John? In low range? EGT's will creep up there easily.
