With the standard system, turning on the fans at a lower temperature does not stop the engine from eventually boiling. It just takes longer.I believe tune ecu let’s you programme the fans to come on earlier and there’s a guy on Facebook who’s selling uprated water pumps......
The downside of reducing the 'on' temperature is that the 'off' temperature is also lowered, to a point at which they may not turn off until you turn off the ignition.. This happened to me. You are just wearing out the fans for no good reason.
If you replace the oem pump with an uprated mechanical pump, you need to be mindful of its operation at peak revs. It is unlikely to pump at full capacity at those revs due to cavitation. If that happens, and you sustain those revs (eg. trackdays) the chances are very high that the engine will overheat. A bad idea when it is producing 100 kW. It will all go to hell very quickly at those power levels.
here's to another year of Benelli riding
TNT 899 (2013)
MV F4 1000 (2010)
TNT 899s (sold)
Tornado 1130 (sold)
Aprilia Dorsoduro 750.(sold)
Of course, I no longer have to worry about it. I have an electric pump capable of 38 lpm which has proven to have solved the problem.
Fitted an upgrade mechanical pump to my original tre. Fully concur with errols concerns re cavitation but to date (and limited miles) it has been fine. Certainly takes longer to get hot and not got close peeing itself so far....used to be a regular occurance.
I have done one very short trackday, which was curtailed by a somewhat painful and very close examination of the grass at craner curves, Donington Park...
Wasnt on the bike long enough to worry about overheating
