I read through all the archives on = evaporator=20 cores and radiators.

I have a few questions for Ed in = particular and=20 anybody else who has any answers or recommendations.

I am going to use radiators mounted = in the wing=20 behind the spar like a ME109. There will be variable inlets and=20 exits.

I have a Ford evaporator core that is = 4 inches=20 thick. The actual core minus the tanks is 8X9 in. So the core volume = is 288=20 in^3. I will use two of these in each wing.

The reason I am interested in this = core is I can=20 use two Fluidyne or Earl's coolers stacked back to back to form a = 4 in=20 thick oil cooler that is the exact same core size as the evap core. = There=20 would be two oil coolers that measure 4X9 in by 4in=20 thick. The hot oil is plumbed into the rear 2in cooler and then = goes into=20 the front 2in cooler.

The evap core and the stacked = oil coolers=20 form a nice cooling block that is 12X12.25X4. All of=20 the plumbing points in the right direction. This is a fast = airplane and=20 will cruise in the 250 mph range, I am not opposed to putting spray = bars in=20 front of the coolers for the occasional very hot day climb. = The=20 coolers are aligned with the outer portion of the prop arc under the = wing so=20 they will be in a fairly high velocity air stream on the = ground.

Do you guys = think that this=20 will be adequate cooling for a Pport = 13b?

Any big = problems with the=20 Ford Evaporator cores VS GM? They look to be the same except for = the=20 thickness and dimensions just happen to coincide with the oil=20 coolers.

Here are the = evap cores 2=20 req:
