Dragy Evaluation: We Placed The GPS Efficiency Meter To The Test
Back in the olden days, when gauging an automobile’s performance, we utilized the seat of our trousers– stating that makes me really feel truly old. Given that we didn’t have a chassis dyno or any kind of fancy electronic gadgets to gauge performance, we needed to improvise well, kind of. We would generally make changes to our vehicles with high-performance parts like sticky tires, camshaft, exhaust, and nitrous, among others. After that, after the installment, we would certainly strike the streets to see if the vehicle really felt any kind of faster. If it did, which was 99-percent of the time due to the fact that we didn’t want to admit the parts reduced the cars and truck down, we mored than happy. Naturally, the method of performance testing was very crude and extremely unreliable.
The Dragy GPS Performance Meter takes the uncertainty out of adjusting and brand-new alterations.
The trouble during this era was that there were only a couple of methods to determine added efficiency: on an engine dyno or at the track. Sadly, our regional track closed down for some time to make issues worse, which meant we needed to take a trip an hour north to examination and tune.At site dragy review from Our Articles That was the only alternative we had at the time. Nonetheless, this is not the instance in this day and age. Also in many towns, you can discover a framework dyno to wheel your vehicle and see if a brand-new product makes a difference. Today there are other advanced approaches that measure efficiency, like a GPS efficiency meter.
The Dragy
One of the much more popular gadgets constantly filling our social media feed is the Dragy GPS Efficiency Meter. And while we know that a lot of you have experience with this product, we have yet to evaluate the unit ourselves, and determined 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 devoted drag racer. For the test, Thompson fulfilled us out at Wichita Raceway Park in Wichita Falls, Texas, where the Quarrel in the Loss no-prep race was happening. His notchback Mustang houses a turbocharged engine, Holley Dominator ECU, and a host of other go-fast goodies.
The bundle includes a Dragy with a magnetic base, 2 steel plates with sticky for installing, and a charging cable.
The Dragy is a quite simple tool outside. It’s absolutely nothing more than a little black box that’s 1-inch vast, 3-inches long, and 1/2-inch tall. The tool has a magnet on the bottom and includes two steel plates with an adhesive that can be mounted on the cars and truck’s interior. It likewise consists of a charging cable; nevertheless, you will certainly need to give a power supply. The only various other point required to make this device work is the Dragy Application, which can be downloaded from the Apple App Shop for an iphone tool or the Google Play Store for an Android. After we loaded the application on the iPhone, billed the Dragy, and updated the software, we were ready to do some screening.
How It Works
The Dragy is easy to use and set up. The system employs high-speed GPS satellites and afterwards determines your lorry’s performance within 1/100th of a 2nd. The software program will certainly tape-record the pass before keeping it on your gadget. You can likewise pick the criteria you wish to test, consisting of 0-30 miles per hour, 0-60 mph, 60-130 mph,1/ 8-mile, 1/4-mile, and 1/2-mile, to name a few. And if that’s inadequate, you can also utilize the custom-made setting and include more settings, 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 interior, we decided to toss it on the roof covering. The magnetic base was solid enough to hold the system in place pass after pass.

x. 5 & Prime; Installation Considering that the magnet
on the Dragy box seemed to be instead strong, we chose to toss the device on the roofing system of Luke’s Mustang rather than on the interior. And while the positioning doesn’t seem to matter for performance, we intended to see if it would certainly hang on during a launch. Plus, the blinking blue LED light in addition to package drew out the Fast and Angry in us –– well, the first motion picture and not the wrong of the most recent, anyway. We additionally used a mobile phone mount which we purchased 5 Listed below for just $5.00. The install had a suction mug on the base, which we installed on the guest side of the windscreen so it wouldn’t remain in the motorist s line of vision
. For video purposes, we also used a mobile phone install which we purchased Five Below for only $5.00. The place had a suction mug on the base, which we installed on the traveler side of the windshield so it wouldn’t be in the driver s line of sight.
At the Strip
As we hit the hosting lanes, we switched on the Dragy and synced it with the application. This process just took a few seconds, and we were ready to go. Luke was racing in the 6.0-index course however had actually refrained any previous screening to make certain the auto was on factor. So as he checked the tune-up one last time in the Holley ECU–– and since Quarrel in the Autumns 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 automobile. While he was switch on the laptop we secured the mobile phone in the install and changed the view for the video. As soon as we were next in line for the fatigue, we hit record and allow the Dragy go to function. We didn’t know if the system would certainly start data logging as quickly as the automobile relocated, which it does. However, after the pass, you can uncheck the things not desired, and the video overlay will certainly show the picked details.
Establishing the Dragy just takes a couple of mins since the app is easy to navigate. You can likewise change the efficiency setting, inspect the leader board, and look at the tempeture, thickness altitude (DA), together with a host of other functions.
Making Passes
Luke lit the tires up in the water box on the Mustang and after that continued to present the cars and truck. After that, as the Christmas tree lit up, he let go of the transbrake and the Dragy mosted likely to function. The auto went a 6.45 e.t. in the 1/8-mile for the first pass, lifting early. After returning to the pits, the Dragy information showed a 6.43 in the 1/8-mile at 81 mph. Unfortunately we couldn’t contrast every one 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. However, it was apparent that the Dragy was close, with a difference of only.02-seconds from the boards.
For the second pass, Luke made some modifications to the cars and truck to attempt obtaining 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 respond the same. Luke managed to run a much faster e.t. this round, at 6.39-seconds. Once again, the Dragy displayed 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 showed that the power was ramped in quicker than in the past 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 returned to the pits to check out the app. It’s basic to make use of and offers a great deal of features. You can establish a garage for your different cars, view background, and it even has a leaderboard that will certainly allow you understand where your times stand all throughout the globe. Our preferred function is the video clip overlay that immediately adds data to the pass. This details can conveniently be cut right from your tool so you can share it on social media or the leader board.
The Dragy’s video clip overlay is smooth. You can even trim the video clip in the application prior to publishing it to social media sites or the leader board.
On the whole, we were very impressed with the Dragy. The system is easy to set up and utilize, the app is easy to use, and you can figure whatever out in just a min or more by scrolling around. Yet most of all, the device is sensitive enough that when you make a horse power modification to the cars and truck, it will sign up, which implies we wear’t need to rely on the seat of our trousers any longer. In the future, we will have the ability to use our Dragy to examine parts and see if they are a renovation or otherwise. The only trouble is finding out exactly how to get our job off the jackstands to test. Yet that’s a different story for one more day.
We wanted to say thanks to Luke for letting us enter his way at Brawl in the Autumns and crawl all over his Mustang. Also intended to thank NXGonzo, Chris Raska of Wichita Raceway Park, and Matt Plotkin for putting on a great event.
