Sport Auto has a Boano in the shop, and I had a chance to work on the cooling system. It’s owner takes this car on the track, and says that she overheats at speed. In normal street driving, the temps seem fine, but oil and water temperatures rise all too high when driven in anger.
This is a very clean straight car with very nice details. I love the simplicity of the older 250 series cars. Everything was previously restored to close to original condition on this car except for the racing seat for the driver.
The engine compartment is largely original except for an external oil cooler and remote oil filter. The radiator had an electric fan installed and should be enough to cool this engine.
The temperature sensor that operates the fan is simply stuck between the fins of the radiator to tell when the coolant needs the help of the electric fan to help cool things down, and an adjustment knob can vary when the fan turns on. Everything seemed to be working normally, but I tried having the fan turn on a little earlier to help cool the radiator before things got too hot. It’s hard to mimic track conditions by driving a car on the street, but the 95 degree day certainly helped!
