Intercooler or "interheater" Cummins 5.9
I was looking at my engine a while back and it appears that the intercooler actually uses engine coolant in the intercooler. If this is the case, then the coolant that you use to HEAT the interior of the bus is the same as what is used to COOL the incoming air charge. Does that make sense?? If I understand intercoolers, it is to take the heat out of the incoming air so it will be more dense when it enters the combustion chamber. I've read articles about cold-air intakes for Japaneese cars and they substantially increase the power. Temperatures are relative. The air may be cooler than without the intercooler, but there still has to be some heat in it.
A solution??? So, I look on ebay and this guy has water pumps that are used on a Ford, F150 Lightning. I bought one. What I would like to do is by-pass the intercooler and send the coolant right back into the engine. Then, construct a totally separate cooling circuit for the intercooler. I'd put in a resevoir tank, a little radiator like what is found in a heater in a car and my pump. The only heat I would be dealing with is that picked up in the intercooler--not the engine itself. Cooler air, more power, more fun.
I do wonder if the engine would run lean with this modification. It is a '90 and it doesn't have a computer to monitor things. Any comments?
