Back in the olden days, when gauging an automobile’s performance, we utilized the seat of our pants– saying that makes me feel actually old. Since we didn’t have a framework dyno or any fancy electronic gadgets to gauge performance, we had to improvise well, sort of. We would basically make changes to our cars with high-performance components like sticky tires, camshaft, exhaust, and nitrous, to name a few. Then, after the installment, we would certainly hit the streets to see if the vehicle really felt any type of much faster. If it did, which was 99-percent of the moment because we didn’t want to admit the components reduced the automobile down, we enjoyed. Of course, the technique of efficiency screening was really crude and extremely inaccurate.
The Dragy GPS Efficiency Meter takes the guesswork out of tuning and brand-new alterations.
The issue throughout this era was that there were just a couple of methods to determine included performance: on an engine dyno or at the track. Regrettably, our local track shut down for a while to make matters worse, which suggested we required to take a trip an hour north to test and tune.you can find more here dragy review from Our Articles That was the only option we had at the moment. However, this is not the instance in this day and age. Even in a lot of towns, you can discover a framework dyno to wheel your vehicle and see if a new item makes a distinction. But now there are other advanced approaches that determine efficiency, like a GPS efficiency meter.
The Dragy
Among the a lot more popular tools frequently loading our social media feed is the Dragy GPS Performance Meter. And while we understand that a great deal of you have experience with this product, we have yet to evaluate the unit ourselves, and made a decision to do just that. For our test, we reached out to a friend of ours, Luke Thompson, proprietor of Mike’s Lube Shop and a passionate drag racer. For the test, Thompson met 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 various other go-fast rewards.
The bundle consists of a Dragy with a magnetic base, 2 metal plates with glue for installing, and a charging cable.
The Dragy is a pretty basic tool outside. It’s nothing greater than a little black box that’s 1-inch broad, 3-inches long, and 1/2-inch high. The device has a magnet on the bottom and comes with 2 steel plates with an adhesive that can be mounted on the vehicle’s inside. It likewise includes a charging cable; however, you will require to supply a power supply. The only various other point called for to make this gadget work is the Dragy App, which can be downloaded and install from the Apple Application Shop for an iphone tool or the Google Play Shop for an Android. After we filled the app on the apple iphone, charged the Dragy, and upgraded the software, we prepared to do some screening.
Just how It Works
The Dragy is easy to use and set up. The device utilizes high-speed GPS satellites and afterwards determines your automobile’s performance within 1/100th of a second. The software will videotape the pass prior to keeping it on your device. You can likewise select the parameters you want to evaluate, including 0-30 mph, 0-60 mph, 60-130 miles per hour,1/ 8-mile, 1/4-mile, and 1/2-mile, among others. And if that’s inadequate, you can additionally use the custom mode and include more settings, which we did, like 60-foot time, 330-foot times, or any others you might need.
While you can place the Dragy on the automobile’s interior, we made a decision to toss it on the roof. The magnetic base was solid sufficient to hold the device in place pass after pass.

x. 5 & Prime; Setup Considering that the magnet
on the Dragy box seemed to be rather strong, we opted to toss the device on the roof covering of Luke’s Mustang as opposed to on the interior. And while the placement doesn’t seem to matter for efficiency, we intended to see if it would certainly hang on during a launch. Plus, the blinking blue LED light on top of package highlighted the Fast and Furious in us –– well, the very first motion picture and not the wrong of the most current, anyway. We likewise utilized a mobile phone mount which we purchased Five Below for just $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 remain in the motorist s line of sight
. For video clip purposes, we also made use of a mobile phone place which we purchased Five Listed below for only $5.00. The place 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 view.
At the Strip
As we struck the hosting lanes, we switched on the Dragy and synced it with the app. This process only took a couple of secs, and we prepared to go. Luke was racing in the 6.0-index course however had refrained any type of previous testing to make certain the automobile was on point. So as he examined the tune-up one last time in the Holley ECU–– and given that Brawl in the Loss was a no-prep race, and he couldn’t go faster than 6.0-seconds for the course –– Luke placed an A-to-B tune-up in the auto. While he was pushing buttons on the laptop we secured the cellular phone in the install and readjusted the sight for the video. When we were successor for the burnout, we struck document and allow the Dragy go to work. We didn’t know if the unit would certainly start data logging as soon as the cars and truck relocated, which it does. Nevertheless, after the pass, you can uncheck the items not wanted, and the video overlay will certainly present the chosen details.
Setting up the Dragy only takes a couple of minutes given that the app is easy to browse. You can also transform the performance mode, inspect the leader board, and consider the tempeture, thickness elevation (DA), in addition to a host of various other functions.
Making Passes
Luke lit the tires up in the water box on the Mustang and then continued to stage the car. After that, as the Christmas tree lit up, he released the transbrake and the Dragy mosted likely to work. The auto went a 6.45 e.t. in the 1/8-mile for the initial pass, lifting early. After returning to the pits, the Dragy data presented a 6.43 in the 1/8-mile at 81 miles per hour. Unfortunately we couldn’t compare every one of the data from the Dragy to the timeslip given that this was a no-prep race –– no slides were being distributed to the racer. However, it was evident that the Dragy was close, with a distinction of only.02-seconds from the boards.
For the 2nd pass, Luke made some modifications 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 were curious to see if the Dragy would certainly react the very same. Luke handled to run a faster e.t. this round, at 6.39-seconds. Once more, the Dragy showed a 6.35, this time at 89.30 mph. And while there was a.04-second difference this go-round, it was still close and showed that the power was ramped in quicker than before with a faster e.t. and far better mph.

Back In The Pits
After making a number of hits with the cars and truck, we went back to the pits to discover the application. It’s basic to use and uses a great deal of functions. You can establish a garage for your different vehicles, sight history, and it even has a leaderboard that will allow you know where your times stand all throughout the world. Our favored feature is the video clip overlay that automatically includes data to the pass. This information can conveniently be cut right from your device so you can share it on social networks or the leader board.
The Dragy’s video clip overlay is smooth. You can also cut the video in the app prior to posting it to social media or the leader board.
Generally, we were extremely satisfied with the Dragy. The system is simple to set up and make use of, the application is easy to use, and you can figure whatever out in simply a min or two by scrolling around. However most importantly, the device is sensitive sufficient that when you make a horsepower modification to the cars and truck, it will certainly register, which indicates we wear’t have to rely on the seat of our pants anymore. In the future, we will have the ability to use our Dragy to check components and see if they are an improvement or otherwise. The only trouble is figuring out exactly how to get our project off the jackstands to examination. Yet that’s a various tale for another day.
We intended to say thanks to Luke for allowing us get in his way at Brawl in the Falls and crawl all over his Mustang. Additionally wished to thank NXGonzo, Chris Raska of Wichita Raceway Park, and Matt Plotkin for placing on a great occasion.
