A trip to the Dynotech Engineering driveshaft facility
Every single one of them was putting power to the racing surface with a driveshaft from the folks at Dynotech Engineering in Troy, Michigan.
The automotive performance aftermarket is a massive market with thousands of companies offering performance components covering literally every item of every performance vehicle in the world so when you consider the list of clients using Dynotech driveshafts - it is clear that there is something very special about their products. I recently had a chance to head to their production facility in Troy, Michigan to check out the shop that builds the racing world’s most widely-used driveshafts as well as their popular offerings for the new Ford Mustang.
As I entered the massive production facility, I could only imagine the size of the assembly line that provides driveshafts for the majority of the current NASCAR race teams but Dynotech General Manager Steve Raymond lead me to a small corner along the rear of the building where every driveshaft Dynotech sells is hand built and balanced by a small team of experts. In this small, isolated corner of the production facility I got a chance to see how a simple looking metal tube is transformed into the driveshafts that power the world’s most powerful vehicles.
If you have dealt with a driveshaft in any way, you can probably imagine that the production is fairly straightforward with the various components being mocked up, then welded together before heading to final assembly – where the magic happens. Each and every driveshaft that Dynotech builds spends an extensive amount of time in the balancing area, as the low and high speed balancing areas are where Dynotech driveshafts separate themselves from any other brand on the market.
Once the driveshaft is welded together and ready for the balancing process it goes into a low speed balancing machine where each shaft is tested at 5,000rpm. Their high performance driveshafts then move onto another balancing machine that spins them at a stunning 8,000rpm, with both machines measuring any vibrations and allowing the driveshaft engineers at Dynotech to apply the proper weights to remove any detectable vibration. What does that mean? Well, when a new Ford Mustang GT is cruising along at 80mph in high gear on the highway, the driveshaft is spinning around 3,500rpm. This displays how much further Dynotech goes to prevent vibration during their production and balancing process. The industry standard for similar spin-balancing on driveshafts is an rpm range between 3,200 and 3,500 with a balance target of 0.20 to 0.35 in-oz compared to the 5,000-8,000 rpm at Dynotech with a balanced to 0.125 or less with a general target of 0.10 - showing how much further Dynotech goes compared to the OEM industry standard.
