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

Back in the olden days, when measuring a vehicle’s efficiency, we used the seat of our pants– stating that makes me feel really old. Because we didn’t have a framework dyno or any kind of fancy electronic gadgets to gauge performance, we needed to improvise well, type of. We would primarily make changes to our cars with high-performance parts like sticky tires, camshaft, exhaust, and nitrous, among others. Then, after the installation, we would certainly strike the streets to see if the lorry really felt any kind of much faster. If it did, which was 99-percent of the moment due to the fact that we didn’t wish to confess the parts slowed down the cars and truck down, we enjoyed. Naturally, the approach of efficiency testing was really crude and extremely inaccurate.

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

The problem during this era was that there were only a couple of ways to measure included performance: on an engine dyno or at the track. Sadly, our local track shut down for a while to make matters worse, which implied we needed to travel an hour north to test and song.Read about dragy review At website That was the only option we had at the time. Nevertheless, this is not the case in this day and age. Even in a lot of small towns, you can find a framework dyno to wheel your auto and see if a new product makes a difference. And now there are other high tech methods that gauge efficiency, like a general practitioner efficiency meter.

The Dragy

Among the much more popular devices continuously loading our social media sites 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 test the system ourselves, and decided to do simply that. For our examination, we connected to a buddy of ours, Luke Thompson, owner of Mike’s Lube Shop and a serious drag racer. For the test, Thompson satisfied us out at Wichita Raceway Park in Wichita Falls, Texas, where the Brawl in the Falls no-prep race was happening. His notchback Mustang houses a turbocharged engine, Holley Dominator ECU, and a host of other go-fast rewards.

The package consists of a Dragy with a magnetic base, 2 steel plates with glue for installing, and a charging cord.

The Dragy is a pretty easy device outside. It’s absolutely nothing greater than a little black box that’s 1-inch wide, 3-inches long, and 1/2-inch tall. The gadget has a magnet under and comes with two steel plates with an adhesive that can be installed on the vehicle’s interior. It likewise includes a charging cord; nonetheless, you will require to offer a power supply. The only various other point called for to make this gadget job is the Dragy Application, which can be downloaded from the Apple Application Shop for an iphone device or the Google Play Store for an Android. After we loaded the app on the iPhone, charged the Dragy, and updated the software, we were ready to do some testing.

How It Works

The Dragy is easy to use and set up. The unit employs high-speed GPS satellites and after that measures your automobile’s performance within 1/100th of a second. The software application will tape the pass before saving it on your tool. You can likewise choose the specifications you intend to evaluate, including 0-30 miles per hour, 0-60 miles per hour, 60-130 mph,1/ 8-mile, 1/4-mile, and 1/2-mile, among others. And if that’s not nearly enough, you can additionally make use of the personalized setting and include even more setups, which we did, like 60-foot time, 330-foot times, or any others you may require.

While you can mount the Dragy on the vehicle’s interior, we chose to toss it on the roofing. The magnetic base was strong enough to hold the unit in position pass after pass.

x. 5 & Prime; Installation Considering that the magnet

on the Dragy box seemed to be instead solid, we opted to throw the unit on the roof of Luke’s Mustang as opposed to on the inside. And while the positioning doesn’t seem to matter for efficiency, we intended to see if it would hang on during a launch. And also, the blinking blue LED light in addition to the box brought out the Fast and Furious in us –– well, the first movie and not the atrocity of the most current, anyhow. We also made use of a mobile phone mount which we bought at Five Below for just $5.00. The install had a suction cup on the base, which we placed on the traveler side of the windscreen so it wouldn’t be in the chauffeur s line of vision

. For video functions, we likewise used a cellular phone mount which we purchased Five Listed below for just $5.00. The mount had a suction mug on the base, which we placed on the traveler side of the windscreen so it wouldn’t be in the chauffeur s line of vision.

At the Strip

As we struck the hosting lanes, we turned on the Dragy and synced it with the app. This process only took a few seconds, and we were ready to go. Luke was competing in the 6.0-index class but had not done any type of prior screening to make certain the vehicle got on factor. So as he checked the tune-up one last time in the Holley ECU–– and because Brawl in the Falls was a no-prep race, and he couldn’t go faster than 6.0-seconds for the class –– Luke put an A-to-B tune-up in the cars and truck. While he was switch on the laptop computer we secured the mobile phone in the mount and adjusted the view for the video clip. When we were next in line for the fatigue, we struck record and let the Dragy most likely to function. We didn’t know if the system would certainly begin information logging as soon as the auto moved, which it does. Nevertheless, after the pass, you can uncheck the items not wanted, and the video clip overlay will present the chosen information.

Setting up the Dragy only takes a couple of minutes considering that the app is very easy to navigate. You can likewise alter the efficiency setting, check the leader board, and check out the tempeture, thickness elevation (DA), in addition to a host of various other features.

Making Passes

Luke lit the tires up in the water box on the Mustang and afterwards continued to stage the car. After that, as the Christmas tree lit up, he released the transbrake and the Dragy went to function. The automobile went a 6.45 e.t. in the 1/8-mile for the initial pass, raising early. After going back to the pits, the Dragy data presented a 6.43 in the 1/8-mile at 81 miles per hour. However we couldn’t compare every one of the data from the Dragy to the timeslip considering that this was a no-prep race –– no slides were being dispersed to the racer. Nevertheless, 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 modifications to the automobile to attempt getting closer to the 6.0-second time slip without blowing the tires off. He ramped in power a little quicker, and we were curious to see if the Dragy would react the exact same. Luke managed to run a faster e.t. this round, at 6.39-seconds. Once more, the Dragy showed a 6.35, this time around 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 mph.

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

Back In The Pits

After making a couple of hits with the car, we went back to the pits to check out the application. It’s simple to utilize and provides a lot of attributes. You can set up a garage for your different automobiles, sight background, and it even has a leaderboard that will certainly allow you recognize where your times stand all across the world. Our favored attribute is the video clip overlay that instantly includes data to the pass. This details can quickly be cut right from your device so you can share it on social media or the leader board.

The Dragy’s video overlay is smooth. You can also trim the video clip in the application before uploading it to social media or the leader board.

Overall, we were very satisfied with the Dragy. The unit is easy to set up and utilize, the application is easy to use, and you can figure every little thing out in just a min or two by scrolling about. Yet most of all, the gadget is sensitive sufficient that when you make a horsepower change to the car, it will certainly sign up, which indicates we put on’t have to rely on the seat of our pants any longer. In the future, we will certainly have the ability to use our Dragy to test components and see if they are an improvement or not. The only problem is finding out just how to get our task off the jackstands to examination. However that’s a different story for an additional day.

We intended to say thanks to Luke for allowing us get in his means at Quarrel in the Falls and crawl all over his Mustang. Also intended to give thanks to NXGonzo, Chris Raska of Wichita Raceway Park, and Matt Plotkin for putting on a great event.
