If you read back a few pages you’ll get the run down, basically I have been doing some testing and taking temperature readings on the return line of the injection pump, where I saw near 180* keeping in mind this is with no hood and 90 mph of air cooling the engine and injection pump. With a closed hood I’m sure the temperatures would exceed 200*
Diesel fuel thins drastically as temperature increases which means the pump is not able to displace as much fuel. Additionally, the increased heat decreases the effectiveness of diesel as a lubricant, and the high temperatures are terrible for longevity of seals.
In short my goals are to lower the fuel temperature to get more fuel out of the stock pump and to possibly increase the longevity of the db2 with less internal heat and better lubrication. We’ll see how far I can get with that
