Additional pressure is required for the disks, hence the reason for the difference in pedal ratios. Don't recall if I updated the tech info after running the s-10 setup for a while. I did drill a new hole lower in the pedal to increase the pressure. This lowered the rod attachment point and increased pressure. Found the need to do this with the 38" tires.
If you desire an assisted pedal feel, a manual master will not provide this. I went from manual drums to the wardens adapter/mini boosted master and hated it. Pedal was way too touchy for me, overboosted actually. The S-10 was a manual disk setup and gave me back the pedal feel I was looking for.
This is not for everyone. Since then, and after dedicating my rig to a full on comp rig, I have modified my firewall and installed the Wilwood manual 3 master pedals. This setup has the correct pedal ratio, and the balancing from front to rear is done by master bore selection, and the adjustable balance bar. No prop valves or residual are used.
This firewall mod was easier than I had previously thought, and frankly I would do it again on a street rig (drum cruiser) to get updated braking.
I also found that that using a seat of the pants/lock up test became useless once I went to the Krawlers, and again when I went to the "red" Krawlers. Funny how little traction the swampers actually provide!
