Intercoolers

Years ago a farmer from the other side of the county had our local dealer put an intercooler on his 8030. I think his 8030 was a stock machine, but i don't know that for sure, and don't know what the horsepower level was on it. I was told that they did a before and after dino test and with the intercooler, the tractor had 2 horsepower less. 

Water coolers are the most efficient - and expensive. Heat 2 pieces of metal and pour water on one and blow air on the other and see which one cools faster. Ford once had a twin turbo engine that used the air from one turbo to blow air through the air to air intercooler.  As the good Doc stated it takes fuel to make hp - the intercooler allows more HP to be made w/o sacrificing engine life due to increased combustion temps.  Also remember that putting on an intercooler will transfer that 300 degree air temp INTO the tractors cooling system sometimes causing heating issues.  All the radiators on 7000 series and 8000 series are the same size (some early 7000 were different) but have more (thicker) rows of flues to handle the increased temps.    As to 'losing hp' I would suspect different temps or some other influence - the intercooler should not have had any affect on HP.  IF the fuel was turned up the engine should have gained hp with the addition. I have always questioned the water flow/efficiency of the AC factory intercooler. On some of the ones we  installer we added a cooler attached to the front grill - ran water from it to the cooler thru a plate we made that was from a rear cap that has a divider in it and tapped two 1/2 pipe holes for inlet and outlet - the other end was stock end cap.  The water goes in the bottom side , goes thru the cooler and up and out the top side or vice versa. There was a bulletin a long time ago that some intercoolers were installed 90 degrees in the housing which virtually negated the effectiveness. Just a long ramble on a rainy day before the temps plunge.

DR is right.... We had 21000 engines in the 21C dozers at 325 HP with a turbo.... Put an intercooler on it and you could CRANK UP THE FUEL PUMP due to the extra air available... That made 375 HP for the 945 wheel loaders (25000 engine)... If you just cranked up the pump on the 21000 it would get excessive HOT and also more black smoke.

Oh yes, it was a water cooled cooler.

7045 radiator has 4 rows of tubes. 7060 has 5 rows of tubes for 20%+ more cooling capacity. 8030/8050 have same radiator size.

7045 and 7060 are thee exact same driveline. 8030 has 2-pinion differential and lighter final drives. Same size equipment a gear faster and that driveline will be OK fine.

The 7060 was more efficient in the Nebraska tractor test than the 7045. The 7020 was more efficient than the 7010. I always thought that was the result of cooler air, but maybe it is the result of cooler air with more fuel that drives that efficiency.

Very interesting topic.
Ive always questioned the water to air coolers, vs air to air.
Ambient air plays such a huge
part.
Running in arizona in july the water version is probably the way to go.
But say running northern canada late fall one would think that cooling the intake air with 32 degree ambient is better than 180 degree coolant.

there must be something with the ATAAC engines, that about all that is on any mobile equipment now days,, so,, WJAC must be a thing of the past, or limited to specific applications?
