Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
60hp would be about right. I’ve read that the cooling fan can pull 20hp as well, so you are at 80hp plus whatever you loose with other stuff spinning. It don’t think they would intend to operate it while it’s driving, so it seems doable. I don’t think it would push the limits of the engine and I’d bet the cooling would keep up (maybe). With the horizontal orientation of the radiator, it doesn’t get the same airflow benefit at speed like normal cars. That fan moves a lot of air when the engine is spun up, whether the truck is moving or stationary.More pics on it on the auction site.
I would guess that unit at full tilt will use at least 50 to 60hp out of the anemic NA 6.5. I would also think cooling would be a big issue with the truck static.

Yeah, but at some point you are maxing out what's possible with a belt driven unit of a reasonable size. From the pics I've seen of the 400a generator, that's got to be pushing the max. That puts out a bit of power, but nowhere near 30kw. I'm guessing this failed because it just makes more sense to buy a generator and stick it in the back of the truck or tow it. PTO-driven generators can make a lot of sense for equipment that has a PTO, but a lot less sense when you have to redesign to accomodate it. Yeah, it's possible to mash it all together and make a hmmwv power station, but it would never make sense adding the complexity in parts, service, etc. when you will still need stand-alone generators.I think they would have been better off with a large alternator and inverter producing 10k watts and spike to 12k. This would be more doable and give a fair amount of power. The electronic governor reliably would be concerning. Just my .02 cents
Then you saw a rare bear. The were only 4 battalions of S/P Hawk. All in Germany. 3/7 ADA, 3/60 ADA, 1/1 ADA and 2/2 ADA. Each had 18 launchers. And there was at least 0ne "Float" to cover things like the burned out track above. There were 2 at the school house in Ft. Bliss.Guyfang, I helped scrap one of those M548's with the 400Hz generator back in the early 90's.
I still have some of the engine parts today.
