Not sure there'd be any benefit as all the heat is produced under boost.

In theory i agree.
.
the amount of airflow a fan can produce is negligible compered to air flow from driving
.
.
but rads have fans so could help
.
.
must admit i'm curios to see if they help air charge temps at all

trust me this is a genuine question

why has every car i've owned over 23 years had a rad fan if it dosent cool the water Peter

up fan be used independently from the engine radiator fan, to help cool a charge cooler radiator? And could it be wired to come on when the car comes to a standstill from maybe the speed sensor? Appreciate any thoughts.

I wired in a fan override switch in the dash that turns both the front fans onto max.
However I don't actually use it!

There is a theoretical benefit IMHO.Keeping the water flowing through the charge cooler as close to ambient as possible is always going to be of benefit, so anything that helps remove heat is good! The question isn't whether the car will be more performant with a mod like that, because the answer is
"yes, although unnoticeably so and only in a small set of situations".
The question is whether the effort is worth a practicably unnoticeable change? I'll agree with Peter here, and say it's unlikely to be worth your time unless you're both a dab hand at electrics and have run out of things to watch on NetFlix!

Agreed.![]()
Theoretical benefit.

But the practical benefit proven by data logging wasn't worth the hassle.

Also depends on the c/c and rad sizes.

Probably core placement too..
.
the ST205 core, although oh so neatly positioned over the cam cover, does heat up relatively quickly if the pump isn't running.

Would love it if someone could give me some tips on how to wire it to the speed sender without it affecting the speedo reading if that's even possible.
