R1 cooling fan, whats the norm?
sdh2903 - 10/5/11 at 07:07 PM

Hi all

I have my r1 4xv lump installed, wired and plumbed and was just wondering how people wire up their cooling fans? I'm using an R1 rad but a beefier 10" fan. It's currently hooked up to the bike engine loom which i beleive controls the fan through the temp switch in the rad.

My question is will this suffice for in a car application? or do people tend to use an adjustable controller or simply a switch in the cabin for when the temps get up?

cheers
Steve

ive seen a few people using the little fiat rads which seem to do the job.

my zzr1100 uses the standard rad but i do see the temps rising higher than i would like. ill go with a bigger rad when ive finished.

upgrading later in the day.

On my 5vy I have the fan controled by both the ECU and a manual override. The rad is a Polo/Golf 1.3. The ECU switches the fan on at 105'c and off at 98'c. Thats fine, but I find the engine easier to stall above 95'c. So I tend to override if I see it creeping up in traffic or have a sudden stop from speed (m/way hold up, etc) where it tends to climb quickly. If I forget the ECU cuts it in before things overheat.

Oddly, if I forget to switch off the override when driving, it runs hotter than without it running.

Sounds very sensible that having the manual and the automatic switch, sounds like a plan!!

As with Adithorp both Blade & R1 use std bike temp switches, but with manual over-ride and warning light, Freaky part is the warning lamp comes on on it's own when driving, think it's something to do with the fan acting as a generator when not in use.
