Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
Yea I wish that info was a little easier to find for the 3116, that and the engagement torque figures(usually specced around 800 RPM for manual transmissions/clutches). Cat made so many different tunes of the 3116 engine for customers it isn’t funny. I ran across an Eaton clutch table that listed peak torque numbers around 1550 RPM for the 3116, but surprisingly had no engagement torque figures listed anywhere. It also didn’t show the 225HP@2600 RPM Tune we have, just a 230@2600 with 605ft/lb@ 1550RPM. From the marine tables I have seen, I am estimating engagement torque just under 200ft/lb@800 RPM. Of course these charts only show the high RPM side of the torque curve…A little more information for those following along. I copied this from the internet somewhere. Torque/horsepower graphics

Perhaps that would be about the ideal, but I don’t know that 7th will be unusable with the 3.9. If peak torque is 1450-1550 RPM, 60MPH in 7th is only going to be ~100-200 RPM below peak torque. 6th and 7th are not really very far apart with 7th being about 87% of the 6th gear ratio(smallest ratio change in the trans).Seems to me the ideal gear ratio might be around 4.30 , makes 7 gear usable and a little lower first. You can put me down for a set for a 1083.
Could you do a video accelerating from a stop to about 55mph?Great to hear the interest, I’m going to produce them! I’m trying to get the EDM cost down. Not a deal breaker either way.
If you get to this area and want to test drive please contact me. You will be impressed with the drivability for sure!
I will be contacting everyone that expressed interest in purchasing these to complete order details. No money will be required until
that order is ready to ship.
Thanks everyone for your comments.
I understand and don’t wish to break the rules. Will limit my info to technical only…. I will Post in the for sale section when they are available…. Sorry for bending the rules.I have cleaned up this thread since it's turning into a classified ad. Or really more of a vendor related ad. It's ok to discuss the technical aspects of this. But there needs to be a ad posted in the correct area when it comes to the sales/marketing of this.
I assume you mean from inside the cab, sure. Will get to it when the roads clean up a bit.Could you do a video accelerating from a stop to about 55mph?
I have visions of parts flying off and the tires exploding......I wonder what would happen to those with the faster gears already installed? I am guessing that would be too far….

I think they would work fine. They would look a little silly on something like my 1079 where it already almost needs larger tires as it's a bit visually out of proportion...Any thoughts on using the smaller tire?
