i would like to report back another successful 150 mile drive.
ambient temps was 51F / 11C
speed varied upto 60mph, it was also raining on and off
running temp is a constant 194-198 deg F (90-92deg c) peaking once i think at 201f (94c) after a long slow climb on a hill. (according to gauge)
i have seen it run 198-203 but on a much hotter day with ambient temperature 77f (25degc).

it was raining today so i got free charge cooling!.
boost is nominally 2-5 psi when just coasting about, when freewheeling its zero of course.
when foot is down i am showing only 6psi max.
The gauge i am using is fairly low cost so i expect a psi or two either way tolerance.
Given the fact it a low HP engine (85ps) and 3500lb weight constantly on boost i think it would be advantageous to intercool it, wether i get the time or not is another factor, it certainly has the room where the stock air filter fits to squeeze in a cooler and fan and a drop the air filter lower


i have not yet dialled in my F5 fan controller properly but it seems to work good, i set the ON temperature fairly low on the POT , so it comes on at a low temperature , i am unsure what the actual temperature is but the way i see it as soon as the thermostat opens at 180f the fans should come on so the 'low' on potentiometer should be lower than the thermostat.
i dont know at which road speed the fans make no difference, i think i'll wire in a dash led so i can have a look at the fan habits at higher speeds.

there is a speed signal cut off for the fans which picks up off the vehicles speed signal wire so if i can find the VSS wire i may use it later.

its a ball driving these vans
