Internal Diameter of Radiator hose
Anyone know the ID of the Radiator hose on the 919? Microfiche pictures I can find just list the part numbers, not any actual measurements.
I'm considering putting a Thermo-Bob in, to get this engine up to a decent temp faster, and keeping at that temp (195-210) more reliably than stock. The manufacturer of this device has a 1 inch ID setup...but if the 919 hoses are larger than that, I don't want to be putting in a bottleneck. Also, I haven't yet been able to find a good diagram of the cooling system to see if this will even be able to be made to work correctly.
