SAE (contact-patch ratio) Hp Capacity:*

*Power capacity is unlimited, but subject to roll diameter-induced tire deformation (safety) and traction (efficiency) limits. Continuous capacity depends on selected absorber and test speeds. Higher torque transfer requires tie downs.
13" = 100 Hp (500 / 1.4"deform*μ) – “scooter duty” tires
16" = 385 Hp (500 / 1.3"deform*μ)
20" = 450 Hp (500 / 1.1"deform*μ)
24" = 500 Hp (500 / 1.0"deform*μ)
Note: μ = 1.00 (coefficient of friction for typical 24"-diameter rubber tire on grooved steel roll).

MPH Range (tire-deformation limited): **

**Range is subject to tire's speed rating (sr) and roll diameter-induced tire deformation (safety) limits.
13" roll = 5 - 100 MPH – “scooter duty” tires
16" roll = 6 - 163 MPH (186sr / 1.3"^.5deform)
20" roll = 7 - 169 MPH (186sr / 1.1"^.5deform)
24" roll = 8 - 186 MPH (186sr / 1.0"^.5deform)
30" roll = 10 - 250 MPH – “Bonneville” tires

Steady-State Power (absorption units):

*Absorber capacities are RPM dependent. Air-cooled absorber loads are rotor temperature dependent. Water brakes require a minimum water flow of 1 gpm @ 30 to 60 psi for every 20 continuous Hp.
