Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
Yes, air-cooled Continental. 1790 CI fed by two massive Stromberg 2 barrel carbs. Each cylinder is dual plugged powered by 4 magnetos.
The big Continental air-cooled gas engines are 895 (opposed 6) or 1790 (V-12) All 1790s are crankshaft-drive centrifugal supercharged. Some 895s are natural single carb.
Right you are!
They do have a great sound!! Its a bit on the scary side when they fire the first time and you don't exactly know whats going to happen but it doesn't take you long to get all happy!! I start ours on a stand we built every few months just to keep them lubed and to hear them!! They will only run about 10min on the 2.5 gallon fuel cell we use (it takes a fair amount of that just to fill the float bowls). After you warm them up and rev them some they will shoot a blue flame 2 ft into the air!!!! Maybe not a good indication of fuel efficency but it sure is cool!!!!
If you ever in Iowa Im just 3 miles off I-80 between Des Moines and Omaha stop in Ill fire one for you. Its way better in person!!I may or may not have watched this video several times.
Just curious...Do you have hulls for your 1790 packs? I drove M-47 as a teenager at an Army Reserve armory, 1959. The unique 'side-stick' steering is memorable. The thing has some WEIGHT. We have a nice M-41 here and it has become (after lots of hours work) a treat to drive. A great crowd-pleaser, not to mention driver-pleaser. Current project is a Stuart, with 6.2 GM/Turbo 400 trans. Runs 30MPH on dirt, sounds fabulous. Turret will go on this summer.
I understand that in certain duty stations in Germany and Korea they installed 24V sump heaters powered by the APU. That sort of thing might be dead-easy to install...even in 115 or 230. I bet you will find the access cover for installing a heater directly in the sump. Our MTU 538s would not crank until oil pressure and temperature were up. Pre-lube pump and heaters are mandatory on ALL big recips.
