Dragy Review: We Placed The GPS Efficiency Meter To The Test

Back in the olden days, when gauging a car’s efficiency, we used the seat of our pants– claiming that makes me really feel really old. Since we didn’t have a framework dyno or any kind of expensive digital tools to determine performance, we had to improvisate well, type of. We would essentially make changes to our vehicles with high-performance parts like sticky tires, camshaft, exhaust, and nitrous, to name a few. Then, after the installment, we would strike the streets to see if the car felt any type of quicker. If it did, which was 99-percent of the moment since we didn’t want to admit the parts slowed the cars and truck down, we mored than happy. Obviously, the method of performance screening was extremely unrefined and very imprecise.

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

The issue during this era was that there were only a couple of methods to measure added efficiency: on an engine dyno or at the track. Unfortunately, our local track shut down for a while to make matters worse, which implied we required to travel an hour north to test and tune.Join Us dragy for sale website That was the only option we contended the moment. Nonetheless, this is not the situation in this day and age. Even in the majority of villages, you can discover a framework dyno to wheel your vehicle and see if a new item makes a difference. Today there are other high tech approaches that measure efficiency, like a GPS performance meter.

The Dragy

Among the much more preferred devices constantly filling our social media feed is the Dragy GPS Efficiency Meter. And while we understand that a great deal of you have experience with this product, we have yet to test the unit ourselves, and decided to do just that. For our examination, we reached out to a friend of ours, Luke Thompson, owner of Mike’s Lube Shop and an enthusiastic drag racer. For the test, Thompson satisfied us out at Wichita Raceway Park in Wichita Falls, Texas, where the Quarrel in the Autumns no-prep race was happening. His notchback Mustang houses a turbocharged engine, Holley Dominator ECU, and a host of various other go-fast rewards.

The bundle consists of a Dragy with a magnetic base, two steel plates with sticky for installing, and a billing cord.

The Dragy is a rather straightforward gadget outside. It’s absolutely nothing greater than a little black box that’s 1-inch large, 3-inches long, and 1/2-inch tall. The device has a magnet under and includes 2 metal plates with an adhesive that can be installed on the cars and truck’s interior. It also consists of a billing cable; nevertheless, you will certainly need to offer a power supply. The only various other point called for to make this tool work is the Dragy Application, which can be downloaded and install from the Apple Application Store for an iOS device or the Google Play Store for an Android. After we filled the app on the iPhone, charged the Dragy, and updated the software program, we were ready to do some screening.

Exactly how It Functions

The Dragy is easy to use and set up. The unit uses high-speed GPS satellites and then gauges your lorry’s efficiency within 1/100th of a second. The software application will certainly videotape the pass before saving it on your gadget. You can additionally select the criteria you want to examine, 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 not enough, you can additionally use the custom-made mode and add more setups, which we did, like 60-foot time, 330-foot times, or any others you could need.

While you can install the Dragy on the vehicle’s indoor, we made a decision to throw it on the roof. The magnetic base was solid sufficient to hold the device in place pass after pass.

x. 5 & Prime; Setup Since the magnet

on the Dragy box seemed to be rather strong, we opted to throw the unit on the roof covering of Luke’s Mustang rather than on the inside. And while the placement doesn’t appear to matter for performance, we wished to see if it would certainly hold on during a launch. Plus, the blinking blue LED light on top of package drew out the Fast and Furious in us –– well, the initial motion picture and not the atrocity of one of the most current, anyway. We also used a mobile phone install which we purchased 5 Listed below for just $5.00. The mount had a suction cup on the base, which we installed on the guest side of the windshield so it wouldn’t be in the driver s line of vision

. For video clip objectives, we also used a cell phone place which we purchased Five Below for just $5.00. The place had a suction cup on the base, which we placed on the guest side of the windshield so it wouldn’t be in the chauffeur s line of sight.

At the Strip

As we hit the staging lanes, we activated the Dragy and synced it with the application. This process only took a couple of secs, and we were ready to go. Luke was competing in the 6.0-index course however had refrained from doing any kind of prior testing to guarantee the vehicle was on factor. So as he examined the tune-up one last time in the Holley ECU–– and because Quarrel in the Falls was a no-prep race, and he couldn’t go faster than 6.0-seconds for the class –– Luke placed an A-to-B tune-up in the vehicle. While he was button on the laptop we protected the mobile phone in the mount and adjusted the view for the video. As soon as we were successor for the burnout, we hit document and let the Dragy most likely to function. We didn’t know if the unit would certainly start information logging as quickly as the auto relocated, which it does. Nonetheless, after the pass, you can uncheck the items not wanted, and the video clip overlay will certainly show the picked info.

Setting up the Dragy just takes a couple of mins considering that the app is simple to navigate. You can likewise transform the performance setting, check the leader board, and take a look at the tempeture, thickness altitude (DA), in addition to a host of other features.

Making Passes

Luke lit the tires up in the water box on the Mustang and then proceeded to stage the automobile. Then, as the Christmas tree lit up, he released the transbrake and the Dragy went to work. The vehicle went a 6.45 e.t. in the 1/8-mile for the very first pass, lifting early. After returning to the pits, the Dragy data showed a 6.43 in the 1/8-mile at 81 miles per hour. However we couldn’t compare all of the data from the Dragy to the timeslip given that this was a no-prep race –– no slides were being dispersed to the racer. Nonetheless, it was obvious that the Dragy was close, with a difference of only.02-seconds from the boards.

For the 2nd pass, Luke made some changes to the cars and truck to try getting 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 react the exact same. Luke took care of to run a much faster e.t. this round, at 6.39-seconds. Again, the Dragy showed 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 in the past with a faster e.t. and much better mph.

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

Back In The Pits

After making a couple of hits with the vehicle, we went back to the pits to check out the app. It’s simple to make use of and supplies a lot of features. You can establish a garage for your various automobiles, sight background, and it also has a leaderboard that will certainly allow you understand where your times stand all throughout the world. Our favorite feature is the video overlay that instantly includes data to the pass. This info can easily be trimmed right from your tool so you can share it on social networks or the leader board.

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

On the whole, we were very impressed with the Dragy. The unit is simple to set up and use, the app is user-friendly, and you can figure whatever out in just a minute or 2 by scrolling around. However above all, the gadget is sensitive enough that when you make a horse power adjustment to the auto, it will register, which means we don’t need to trust the seat of our pants any longer. In the future, we will have the ability to use our Dragy to evaluate parts and see if they are an improvement or otherwise. The only problem is determining how to get our job off the jackstands to examination. Yet that’s a different tale for an additional day.

We wanted to say thanks to Luke for letting us enter his way at Brawl in the Falls and crawl all over his Mustang. Likewise wanted to thank NXGonzo, Chris Raska of Wichita Raceway Park, and Matt Plotkin for putting on a fantastic occasion.
