I agree. 400 amps at 24 volts is STILL only 9600 watts or 13 hp. Yes, an "array" of fans might be able to better utilize the surface area of a rectangular radiator, but it's still not much actual POWER to pull air through.Hal wrote:The electric fan package Chris refers to is a group of 8 fans in a 31"x51" design. It draws 400 amps, 24 volts. It would probably require a custom radiator and structural modifications to fit the bus. Even then, it may not be enough cooling to handle a high hp, heavy conversion in hot weather.
The tried and true belt and fan system can always be made to work when installed properly.There's a reason the OE's didn't use electric motors....
Good luck,Hal

Re: Model 01 with Cummins L10 overheating issue
During the course of another thread, an author reminded me that “all of us here do things differently…” Although I am somewhat at a loss over the response, I nonetheless tried to keep it in mind.
Hal, I can’t agree more. I just thought that IF an electric radiator fan system is preferred at any cost, THEN Engineered Machined Products, Inc. headquartered in Escanaba, MI can probably come up with the best solution.
EMP is currently the #1 manufacturer of diesel engine pumps in North America having established a solid market share. EMP has also built a solid reputation in the heavy-duty/diesel industry for its advanced R&D engineering capabilities. They are certainly qualified to provide solutions linked to problems with misapplied thermodynamics. They also make a 450 Amp, 24VDC, brushless alternator – a perfect Delco 50DN drop-in replacement.

Re: Model 01 with Cummins L10 overheating issue
Ahoy, Eagles,
The L-10 engine included a varient which used very small coolant plumbing, and a charge cooler in the intake manifold. This may or may not be a factor regarding the true engine configuration /coolant configuration of this bus.
EagleFolk with good knowledge of Cummins may be able to expand on this matter.
I agree with Hal -- Go with an engine driven fan. Far more efficient, powerful, simple and far less expensive.
My M-11 Cummins with a 34" 12 bladed fan running at 60% of engine speed is almost off the bottom of the fan power map at 1600 engine rpm, and NO cooling problems.
I have my removed Laycock fan overdrive unit listed on the Eagle Mall. With all the informed talk about cooling problems, I thought that it would be fought over and sold in an hour.
Not so. I guess that the cooling problems being discussed are not serious enough to do something about.
Enjoy /s/ Bob
