i took the bus out for a test run yesterday, maybe put 50-60 miles on it with just the cooler hooked up. no electric fans yet.
the bus ran great!!! on the interstate i hit 70 a couple of times which is real rare. before i thought my top speed was ~67mph, but i gained a bit of power/speed with the cooler transmission.
temps this week and last are right around 100f everyday, and the truck was running good and cool. the truck did get hot enough to kick the fan clutch in once, but overall, it was running cooler than expected.
this morning, i finish up the install of the cooler by adding 2 fans to the cooling system. one fan pulls air through the cooler, and the other fan i just mounted to the front of the intercooler to blow air when temps get up there.
i also wired the fans through a relay so that i can have them run off of a thermostat or i can turn them on manually in the cab with a button on the driver's control panel.
here's the fan one the trans cooler:
here's the new fan on the bus:
i got the fans from JEGS, they were cheap enough that i got 2 to make sure i got the right size. i knew i'd find a use for fan #2.
if i was gonna redo this, i see in the JEGS catalog, the have some nice coolers from Derale called "hyper cooler remote cooler", i'd probably start with that instead of what i did.
i'm done with the cooling system, gona see how this runs for a bit, probably update if i change fluids.
