Wait my math was wrong.

heheh
i even had the guy who made that excel sheet check it out. he says its even better if i limit it to 8 inches of travel i would be 2.8
all good this is why we double check stuff. thanks

Well, if you increase steering angle, no need to limit it.
What people often mistake is that if you increase the angle it won't feel like you're increasing your steering ratio. It just goes further.
2.8 turns for 8" or 3.3 turns for 9.375" will feel the exact same and draw the same amount on the pump.
As an FYI :
piston area on this ram is 6.08 - 2.46 = 3.62
piston area on a regular 2.5 PSC ram is 4.91 - 1.77 = 3.14
You're gaining 15% of power and a shit ton of shat strength.

I did some rough calculator maths with a bit of computer sketching to figure out what size ram to use on the new build. Trying to get 45deg of steering requires shorter steering arms for a given ram throw. So a 2.5x8 cyl needs shorter arms than a 2.5x10 cyl, and subsequently will have a harder time turning the knuckle when bound up even though both of those rams produce the same force.
I was wondering if a 2.5x10 would be close enough to a 3x9 in force to make it worthwhile to use. Turns out the 3x9 still makes a good chunk more torque around the ball joints than a 2.5x10 ram would. Like not even close.
