The Mustang Dyno MD-1100-SE is a serious piece of hardware. It's built with massive 30-inch diameter balanced rolls and a dynamic strain-gauge load cell capable of measuring up to 3,000 HP while handling 900 HP of steady-state peak absorption.
The legacy PowerDyne software on older Mustangs is a massive liability for modern tuning due to archaic polling rates, so the fact that Bob has the Holeshot web-based controls upgrade changes the math entirely. The Holeshot conversion—which sheds Windows for a Linux Ubuntu OS server and utilizes a DAC32 micro-processor with an updated Jbox DAQ—costs between $14,990 for a single absorber and $16,240 for a dual absorber setup right out of the Mustang catalog.
Because of that modern software architecture, a clean, calibrated MD-1100-SE with functional air-cooled eddy current power absorbers (PAUs) and good roller knurling commands a premium. On the private market, this rig is solidly in the $35,000 to $45,000+ bracket depending on condition and shipping logistics. If it has the dual-absorber setup, do not let it go for less than $40K to a shop that knows what they are looking at.
