Dragy Testimonial: We Put The GPS Efficiency Meter To The Test

Read 6 minutes

Back in the olden days, when measuring a vehicle’s performance, we utilized the seat of our trousers– claiming that makes me really feel actually old. Because we didn’t have a framework dyno or any type of fancy digital gadgets to determine efficiency, we needed to improvise well, kind of. We would generally make changes to our lorries with high-performance components like sticky tires, camshaft, exhaust, and nitrous, among others. After that, after the installation, we would strike the streets to see if the car really felt any quicker. If it did, which was 99-percent of the time due to the fact that we didn’t wish to admit the components reduced the automobile down, we were happy. Of course, the approach of efficiency screening was very crude and very incorrect.

The Dragy GPS Efficiency Meter takes the uncertainty out of adjusting and brand-new adjustments.

The trouble throughout this age was that there were just a number of means to measure included performance: on an engine dyno or at the track. Regrettably, our regional track shut down for some time to make matters worse, which indicated we needed to travel an hour north to test and about it from Our Articles That was the only alternative we had at the moment. Nonetheless, this is not the instance in this day and age. Even in the majority of villages, you can locate a chassis dyno to wheel your vehicle and see if a brand-new item makes a difference. Today there are other advanced approaches that determine performance, like a GPS performance meter.

The Dragy

Among the a lot more popular gadgets frequently filling our social media feed is the Dragy GPS Performance Meter. And while we know that a lot of you have experience with this product, we have yet to evaluate the device ourselves, and chose to do just that. For our test, we reached out to a good friend of ours, Luke Thompson, owner of Mike’s Lube Shop and a passionate drag racer. For the examination, Thompson fulfilled us out at Wichita Raceway Park in Wichita Falls, Texas, where the Brawl in the Loss no-prep race was taking place. His notchback Mustang houses a turbocharged engine, Holley Boss ECU, and a host of various other go-fast goodies.

The plan consists of a Dragy with a magnetic base, 2 metal plates with glue for mounting, and a billing cord.

The Dragy is a pretty straightforward gadget on the outside. It’s absolutely nothing greater than a little black box that’s 1-inch wide, 3-inches long, and 1/2-inch high. The tool has a magnet under and features 2 steel plates with an adhesive that can be mounted on the auto’s inside. It likewise includes a charging cord; however, you will certainly require to give a power supply. The only other point required to make this gadget work is the Dragy Application, which can be downloaded and install from the Apple App Store for an iOS device or the Google Play Shop for an Android. After we filled the application on the iPhone, billed the Dragy, and upgraded the software application, we prepared to do some screening.

How It Functions

The Dragy is easy to use and set up. The system employs high-speed GPS satellites and after that measures your automobile’s efficiency within 1/100th of a 2nd. The software will tape-record the pass before storing it on your device. You can likewise choose the specifications you intend to test, consisting of 0-30 mph, 0-60 miles per hour, 60-130 mph,1/ 8-mile, 1/4-mile, and 1/2-mile, to name a few. And if that’s inadequate, you can additionally utilize the custom mode and add more setups, which we did, like 60-foot time, 330-foot times, or any others you could require.

While you can place the Dragy on the automobile’s indoor, we decided to throw it on the roofing. The magnetic base was solid sufficient to hold the device in place pass after pass.

x. 5 & Prime; Setup Given that the magnet

on the Dragy box appeared to be rather strong, we chose to throw the system on the roof of Luke’s Mustang rather than on the interior. And while the positioning doesn’t seem to matter for efficiency, we intended to see if it would hold on throughout a launch. And also, the blinking blue LED light on top of the box highlighted the Fast and Furious in us –– well, the very first film and not the wrong of the most recent, anyway. We likewise utilized a cell phone install which we bought at 5 Listed below for only $5.00. The place had a suction cup on the base, which we mounted on the guest side of the windshield so it wouldn’t be in the driver s view

. For video functions, we also utilized a cellular phone install which we purchased 5 Listed below for just $5.00. The place had a suction cup on the base, which we placed on the traveler side of the windscreen so it wouldn’t be in the driver s view.

At the Strip

As we hit the hosting lanes, we activated the Dragy and synced it with the application. This procedure only took a couple of seconds, and we were ready to go. Luke was racing in the 6.0-index course but had actually refrained any prior screening to make certain the auto was on factor. So as he inspected the tune-up one last time in the Holley ECU–– and since Brawl in the Autumns was a no-prep race, and he couldn’t go much faster than 6.0-seconds for the course –– Luke placed an A-to-B tune-up in the vehicle. While he was button on the laptop computer we safeguarded the cell phone in the mount and adjusted the view for the video. When we were next in line for the fatigue, we hit document and let the Dragy go to work. We didn’t know if the unit would certainly start information logging as soon as the car moved, which it does. Nevertheless, after the pass, you can uncheck the things not desired, and the video clip overlay will certainly display the selected info.

Setting up the Dragy just takes a few mins since the application is easy to navigate. You can likewise alter the performance setting, check the leader board, and take a look at the tempeture, density elevation (DA), together with a host of various other attributes.

Making Passes

Luke lit the tires up in the water box on the Mustang and then continued to present the vehicle. After that, as the Xmas tree lit up, he released the transbrake and the Dragy went to work. The car went a 6.45 e.t. in the 1/8-mile for the first pass, raising early. After returning to the pits, the Dragy information displayed a 6.43 in the 1/8-mile at 81 miles per hour. Regrettably we couldn’t contrast all of the information from the Dragy to the timeslip considering that this was a no-prep race –– no slides were being distributed to the racer. Nonetheless, it was noticeable that the Dragy was close, with a distinction of only.02-seconds from the boards.

For the second pass, Luke made some adjustments to the automobile to try obtaining closer to the 6.0-second time slip without blowing the tires off. He ramped in power a little quicker, and we wondered to see if the Dragy would certainly respond the same. Luke took care of to run a quicker e.t. this round, at 6.39-seconds. Again, the Dragy presented a 6.35, this time at 89.30 miles per hour. And while there was a.04-second distinction this go-round, it was still close and revealed that the power was ramped in quicker than before with a faster e.t. and better miles per hour.

Luke Thompson makes a hit in his turbocharged Mustang with the Dragy mounted on the roofing of the automobile.

Back In The Pits

After making a couple of hits with the vehicle, we returned to the pits to check out the application. It’s straightforward to make use of and supplies a great deal of attributes. You can establish a garage for your different autos, sight background, and it also has a leaderboard that will certainly allow you know where your times stand all across the world. Our preferred attribute is the video clip overlay that instantly includes information to the pass. This info can conveniently be cut right from your gadget so you can share it on social networks or the leader board.

The Dragy’s video overlay is smooth. You can also cut the video clip in the app before publishing it to social media sites or the leader board.

Overall, we were really impressed with the Dragy. The unit is easy to set up and make use of, the app is easy to use, and you can figure every little thing out in simply a minute or 2 by scrolling around. But above all, the gadget is sensitive enough that when you make a horse power modification to the vehicle, it will certainly register, which implies we wear’t need to rely on the seat of our trousers anymore. In the future, we will have the ability to utilize our Dragy to examine parts and see if they are a renovation or otherwise. The only trouble is identifying just how to get our task off the jackstands to test. But that’s a various tale for an additional day.

We intended to thank Luke for letting us get in his method at Quarrel in the Loss and crawl all over his Mustang. Additionally intended to say thanks to NXGonzo, Chris Raska of Wichita Raceway Park, and Matt Plotkin for putting on a fantastic event.
