Passing the Test

May 3, 2013

With dynamometer testing, speed shops can quickly learn where to find more power and efficiency.

Designed to be a realistic simulation of real-world driving and racing conditions, dynos allow technicians to save time and money by fine-tuning in the shop before ever hitting the road, while proving the power upgrades particular products provide.

A serious investment with serious potential, it makes sense to fully investigate the types of dynos available, their strengths, and how they can best-serve your shop, your customers and even potential partners that can elevate your business in the surrounding area.

The following is a roundup of some of the latest dyno products available to the performance aftermarket, their features and ways shops can use these important tools to increase the quality of their work.

Our hottest new dynamometer product is…

…our Motoring AC Dynamometer Systems. These systems are available in our rolling-road, axle-hub and engine dynamometer configurations.

Its best features include…

…an example can be found on our axle-hub dynamometer system. These units can come equipped with our ActiveSync Modules that deliver axle synchronization-precision matching of the unpowered axles during 2WD dyno testing.

The AC dynamometers’ best features include precision load control with a typical response time of less than 0.01 seconds, for a 90-percent load change. AC dynamometers are low-inertia systems that provide instantaneous reaction times and are best used to simulate the inertia associated with different types of driving cycles (required for emissions-style testing).

New technology is affecting the dyno market by…

…above all, these dynamometers have the ability to motor your test engine. In addition to providing convenient engine starting, motoring allows for testing friction losses. This is why these systems are a must-have tool for serious performance shops.

Smart shops use dyno test results to increase business by…

…today’s fuel efficiency requirements mandate that all engine developers try to reduce parasitic losses (i.e. friction), whether it be through the driveline or engine components. If friction can be reduced, that translates to more available power to the rear wheels and increased efficiency.

An added bonus for shops offering dyno services is…

…shops offering AC dyno services have the ability to use the power produced by the motor while it is operating in generator (load) mode and return it to the electric grid via a regenerative unit.

Regeneration can use the test engine’s power to actually lower your shop’s monthly electrical bill. This is something that a standard water-brake or eddy-current absorber cannot do.

Our hottest new dynamometer product is…

…the refined SF-Blackwidow. It’s a dynamometer we launched in 2010, but recently made several enhancements that took it from a custom, application-specific dynamometer to a turnkey piece for high-horsepower and high-torque engines.

We added the Boom system found on both the SF-902S and SF-Powermark dynamometers, added an integrated dual starter and standardized on the same driveshaft and adapter system used on the SF-Powermark so they are easier to build and they offer more available options for different testing needs. We also changed the water system to enhance control and repeatability.

Its best features include…

…its versatility. We use it in many different applications, ranging from performance diesels to Pro Mod motors. The absorber itself has incredible low-end torque capacity, but can still spin to 11,000 rpm intermittently, so the high-power Pro Mod engines are also a great fit.

New technology is affecting the dyno market by…

…demanding more integration between the dynamometer controls and software and ECUs. We’ve got some really exciting things to announce in this area in the next quarter.

Dynos are a must-have tool for serious performance shops because…

…there are a couple of good reasons to have a dyno. One, they offer credibility to the shop, allowing it to instantly prove its worth by backing up performance upgrades with proof.

Secondly, they are a profit center if advertised correctly. We’ve got engine and chassis dyno customers that are booked months in advance for dyno services.

An added bonus for shops offering dyno services is…

…up-selling power adders. This is a common thing many shops don’t pay attention to, but having a skilled dyno operator with some sales savvy can really increase parts sales.

Our hottest new dynamometer product is…

…Dyno X. New for 2013, Dyno X is an affordable dynamometer that includes load control. The new VS (Value Series) lineup of dynamometers is low on price but high on features. You can tune on them with Steady State graphing, the Auto Weather Station automatically compensates for temperature, pressure and humidity variations, and their compact footprint allows convenience of positioning in both smaller workshops and a home garage.

Power capabilities are 0.5- to 800-plus max horsepower and 600-hp steady state max speed of 155 mph. They feature industry-standard knurled rollers and are also available in AWD.

Its best features include…

…price! And they are made in the U.S.

New technology is affecting the dyno market by…

…the same way ever-changing technology affects the rest of the world. For example, our latest software runs on Windows 8.

Dynos are a must-have tool for serious performance shops because…

…you can’t go 240 mph on the street without getting a ticket.

Smart shops use dyno test results to increase business by…

…selling more products. Just show customers before-and-after graphs.

An added bonus for shops offering dyno services is…

…drivability. Even if there is 6 feet of snow on the ground, you can still test and tune on the dyno.

Our hottest new dynamometer product is…

…Stuska Power Pro operators can now retrofit their existing system and add 16 more sensor inputs. This has been largely driven by the increased use of multiple O2 sensors. This includes four more pressures. Battery voltage can be recorded and we can work with a variety of third-party sensors.

Along those same lines, last year we upgraded 20-year-old data systems for several customers. This enables them to operate their older-style control panel data system through a computer and take advantage of most all of the features in our Power Pro Data Acquisition software. At some later date they can update electronics and enjoy the rest of the current features and technology.

We have also made a few small changes with hardware and the Track Master frame. We build most everything ourselves here at Power Test Inc. Our employees are on the lookout, with skills and new ideas for continually improving our manufacturing process.

And as long as I am talking about our team, Stuska Dynamometer is proud to congratulate all Power Test employees for winning the Wisconsin Manufacturer of the Year award!

Its best features include…

…our Stuska Track Master dynamometer and test systems are intended to enable our customers to easily repeat their test procedures with confidence, discovering if the variable they are testing is a good one (or not). Customer feedback is very important in knowing that our dynamometers are achieving this purpose.

New technology is affecting the dyno market by…

…there is a lot of chicken-and-egg going on here. Evolving engine technology creates new dynamometer features and testing procedures. Of course, many new engine technologies are developed and proven by testing with a dynamometer.

Look for electronically managed engines to keep growing in the performance markets. There will be learning curves and even psychological hurdles to overcome. But as we see performance-oriented consumers embrace this, you have to believe that more will come.

Dynos are a must-have tool for serious performance shops because…

…otherwise, how do you know for sure? Engine testing is the last step in your production. When you break-in and tune the engine, you gain an incredible amount of control that is otherwise left in the hands (or foot) of others. Trust me when I tell you, after 25 years of driving around in circles turning left, using racecar drivers may not be the most consistent break-in procedure out there!

Smart shops use dyno test results to increase business by…

…producing quality engines. The efforts of your labor will shine in the marketplace.

An added bonus for shops offering dyno services is…

…I’ve probably said it before, but the first time the dynamometer “proves it to ya” is genuine fun.

Our hottest new dynamometer product is…

…the AWD-150 Series.

Its best features include…

…the AWD-150 series is based on our well-known and very popular AWD-500 mechanically linked series, but streamlined to decrease cost and the overall physical footprint. The AWD-150 has been on the market for over a year and the response has been extremely positive, especially since it offers a non-linear load control system that allows the user to perform true road load simulations.

This technology is accomplished with Mustang Dynamometer’s exclusive closed-loop control system, and Powerdyne software that allows the user to tune the cars properly right there in their shop, safely on the dyne instead of out on the roads. You can also tune the vehicle for optimal 1/8- and 1/4-mile drag racing, or even other types of racing like the Texas Mile.

Because the Powerdyne software allows for the actual vehicle weight and horsepower at 50 mph to be entered, it then allows the vehicle to be loaded correctly just like it would be if it was accelerating down the track, due to the wind coefficients being applied.

Most of these systems are being installed above-ground using our new lightweight composite ramps, which save the customer the expense of having to construct a pit. Our customers have been tuning cars well over 1,000 hp, and the AWD linkage maintains speeds at both axles.

New technology is affecting the dyno market by…

…today’s vehicles are getting smarter, and they can truly sense whether they are on the road or not, and some vehicles will actually go into a limp mode if it is not sensing that it is on the road. This will make tuning on a dyne impossible, and you will be forced to then go street-tune.

Mustang Dynamometer’s advanced engineering department helps put an end to street tuning by synchronizing the two beds via mechanical linkage. This technology in combination with Mustang’s non-linear load control system and Powerdyne software helps to make these smarter vehicles think they are actually on the road.

This technology also assists with the older (less intelligent) vehicles as well.

Dynos are a must-have tool for serious performance shops because…

…a dynamometer helps bring professionalism into any shop, just like an X-ray machine will do for a doctor’s office. Mustang dynamometers have been and continue to be the key to bridging the gap between delivering performance parts and delivering performance.

Our clients use our product every day and it really is an extension of the professional tuner’s skill sets-without the tuner, the dynamometer is useless and vice-versa. The Mustang dyno allows a professional tuner to deliver his or her skills to the marketplace by harnessing their knowledge and translating it into automotive performance for their customers.

Smart shops use dyno test results to increase business by…

…leveraging skills sets and knowledge. In a competitive marketplace the better, more experienced professional has to communicate their strengths to customers in a variety of ways. The dyno is only one way, but it is probably the most important.

The Mustang dyno serves two purposes really, one being to provide for a means to tune a vehicle safely and properly. It also provides a means to validate the work that was done and to show actual, tangible results. Our clients know these results translate to the real world, and this is the desired advertising-a happy client with a very fast car.

An added bonus for shops offering dyno services is…

…the ability to market services to other shops that have not yet made the financial decision to obtain their own dynamometer. Business-to-business marketing is an excellent means to stabilize revenue, and it is also an excellent networking opportunity.

Plus, a Mustang Dynamometer chassis dynamometer system with its state-of-the-art Powerdyne software also allows shops to solicit fleet accounts for diagnostics, and validations of such things like meter drops for taxi companies, or speedometer accuracy for AAA or police departments.
