I've never been a fan of the Gates flexible hoses having used the Vulcoflex type in the past (maybe new version is different?).  They tend to take a fair bit of force to form a curve.  Good for mocking up a system though.

Thanks, I've got the Viperperformance hoses coming too, so I'll be able pick the better hose from that.

Mine does none of this now, stays nice and warm. Let us see what does it say to the race track.

Unfortunately the GoPro went flat, I thought charging it off the PC all day would work, guess there wasn't sufficient current from the USB when the PC was in standby.  Also didn't get an amazing run, however there's certainly enough data from the Easimap capture.

If anyone wants to take a look, here's the capture in csv and native easimap.

Having studied my chart now, knowing where I was and the speed etc. I would suggest this has more to do with the force on the thermostat rather than volume of air passing through the radiator.  The initial drop off in my graph was caused by strong use of RPM, but not high speed.  Higher speed sections over the mountain were actually lower RPM and didn't result in as much cooling, although I appreciate the temps were much lower by then.

Could this not be proved, disapproved by just revving the engine when parked up.

Replied.  -- Easimap logging setup.

Btw, the work we did last year on the ECU should provide the option to permanently log the car from the OBDII without the need for a laptop and then export in a similar fashion.  We should be able to to get the hardware to around the size of a credit card, costing about 60GBP.   Sadly it's just time and motivation to finish the project.  Hopefully, we can get there, and share the solution.
