"REVERSE-ENGINEERING A TIME SLIP IS LIKE SOLVING A CRIME SCENE WITH NO WITNESSES - EVERY NUMBER IS A CLUE, BUT THE REAL STORY IS WHAT HIDES IN THE PHYSICS." DYNAMO HUM AUGUST 2025
Welcome
Here is what our Dragy-Dyno Excel Programs can do for you.
Calculate HP and TQ that your car produces on any particular 0-60, 40-100, 60-130 dragy pull or full Quarter Mile pass. Several of the programs will correct your Elapsed Time and Velocity for % Road Grade, Track Wind Speed & Direction. ​
If you don't own a dragy GPS device, no problem, simply input the data from any NHRA or IHRA Drag Strip Time Slip and our Extraction Programs will pull out the 0-60, 40-100, 60-130 and Quarter Mile Performance Profiles of your car automatically in each of those categories
There are a total of over 30 different Performance Metrics that our various Dragy-Dyno programs can reveal about your car including Hook Rate, Jerk, BMEP, Indicated HP, Brake HP, Wheel HP, Tractive Effort, Optimum Shift Points, WHEELSTAND ABILTIY (Patent Pending) and DYNAMIC DRIVETRAIN EFFICIEINCY (Patent Pending) simply by inputting the results of a dragy device 60-130 Performance Report THAT YOU ALREADY HAVE STORED ON YOUR PHONE
Included in some versions of the Dragy-Dyno programs are some fun tools that provide quick answers owners want to know. You can input a weight loss (or gain) for your car and the program will tell you how it will effect your ELAPSED TIME and VELOCITY. Tell the program how much time you want to shave off your current best 0-60, 60-130 or Quarter Mile Elapsed Times and the program will tell you how much MORE WHP you need to achieve it.
The programs will take the atmospheric condition data that is provided on the dragy Performance Report and use it to calculate all the required metrics to calculate HP and TQ to within 1%. IMPORTANT NOTE: The DA provided by your dragy Performance Report is a fair estimate at best. QUARTERMASTER SOFTWARE WILL CORRECT THE DENSITY ALTITUDE.
Who is Dynamo Hum?
​​
I was born in the Bay Area of California but grew up along the North Coast of the U.S. As a young teen in the late 1960s, I watched my father race our family’s 1965 Ford Country Squire station wagon at the dragstrips of northeast Ohio. Then, in early 1969, my mother gave him the green light to buy a brand-new Crystal Blue Dodge Dart 340 Swinger—column-shifted 3-speed TorqueFlite, no radio, all go. I still remember his first pass at Dragway 42 later that September and how thrilled he was to run a 14.97-second quarter mile. Back then, cracking into the 14s meant you were officially “fast.”
My high school years were pretty average academically, but I was locally famous thanks to Dad owning one of the quickest street cars in Euclid, Ohio. After graduation, I joined the U.S. Navy with my best friend Chris, eager to see the world. Coincidentally, I was stationed just 80 miles from where I now live in Florida.
After earning my first degree in mechanical design, I moved to Houston in 1980 and began working in the booming oil and gas industry. Over the next 19 years, I got married, raised three daughters, and worked in engineering departments across several energy firms. I completed my undergrad studies at the University of Houston with a BS in Structural Engineering & Analysis—along with the Outstanding Engineering Graduate Award for my class. My employer later sent me back to school, where I earned an MBA in Finance and Statistics from Houston Baptist University.
By 1996, after wrangling with Einstein’s shadow and deciding theoretical physics had enough smart minds already, I returned to Ohio to wrap up my career. I spent the next 20 years designing scroll compressors for A/C and refrigeration systems, eventually earning a master’s in Project Management from Georgetown University in DC.
As a hobby, I began crafting Excel spreadsheets to calculate horsepower and torque from quarter-mile times—simple tools at first, but deeply rooted in real-world data. By 2019, the 60–130 mph Dragy benchmark was gaining traction as the new quarter-mile surrogate, so I shifted my focus. One day, I stumbled across a Mustang forum where someone asked, “Can Dragy’s 60–130 time determine horsepower?” Most said no, or “maybe a rough estimate.” I chimed in with, “Sure you can”—because I already had.
Despite pushback from postgrad and PhD math candidates claiming there wasn’t “enough information,” I had developed the math to prove otherwise. I was even booted from a physics and math forum for insisting it could be done—one admin flat-out called me “delusional.” I took it as confirmation I was on the right path.
Back at the ranch, I went further. I refined the equations needed to calculate a drivetrain’s dynamic efficiency during acceleration—and then developed the math required to predict when and how far a car is likely to lift its front wheels off the ground. We used to just call that a wheelie.
Now, as of July 2025, I’ve decided to share my Excel programs at bargain prices so the Dragy crowd can finally unlock the wealth of performance data hiding inside their time slips and GPS logs. Because there's way more in there than most people realize—and I’ve got the math to prove it.
