We would basically 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 hit the streets to see if the car really felt any type of faster. If it did, which was 99-percent of the moment because we didn’t want to admit the parts reduced the automobile down, we enjoyed. Obviously, the approach of performance screening was extremely unrefined and extremely inaccurate.
The Dragy GPS Efficiency Meter takes the guesswork out of adjusting and new alterations.
The trouble during this age was that there were just a number of means to measure included performance: on an engine dyno or at the track. Sadly, our neighborhood track shut down for some time to make matters worse, which meant we required to take a trip an hour north to examination and tune.Read about dragyreview.com At website That was the only choice we had at the time. Nevertheless, this is not the situation in this day and age. Even in many small towns, you can find a chassis dyno to wheel your automobile and see if a brand-new product makes a distinction. Today there are various other advanced methods that determine efficiency, like a GPS efficiency meter.
The Dragy
One of the extra prominent devices regularly filling our social media feed is the Dragy GPS Efficiency Meter. And while we know that a lot of you have experience with this item, we have yet to test the unit ourselves, and chose to do simply that. For our test, we reached out to a buddy of ours, Luke Thompson, proprietor 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 Falls no-prep race was taking place. His notchback Mustang houses a turbocharged engine, Holley Dominator ECU, and a host of various other go-fast goodies.
The plan consists of a Dragy with a magnetic base, two metal plates with sticky for placing, and a billing cord.
The Dragy is a pretty easy gadget on the outside. It’s nothing more than a little black box that’s 1-inch large, 3-inches long, and 1/2-inch tall. The gadget has a magnet on the bottom and includes 2 metal plates with an adhesive that can be installed on the car’s interior. It likewise includes a billing cable; however, you will certainly need to provide a power supply. The only various other point called for to make this device work is the Dragy Application, which can be downloaded from the Apple Application Shop for an iOS device or the Google Play Store for an Android. After we packed the app on the iPhone, charged the Dragy, and upgraded the software, we prepared to do some screening.
Exactly how It Works
The Dragy is easy to use and establish. The system employs high-speed GPS satellites and then gauges your car’s efficiency within 1/100th of a second. The software program will tape-record the pass prior to keeping it on your gadget. You can additionally choose the parameters you intend to evaluate, including 0-30 mph, 0-60 miles per hour, 60-130 mph,1/ 8-mile, 1/4-mile, and 1/2-mile, among others. And if that’s insufficient, you can also make use of the personalized setting and include more setups, which we did, like 60-foot time, 330-foot times, or any others you may need.
While you can install the Dragy on the car’s indoor, we decided to throw it on the roof covering. The magnetic base was solid sufficient to hold the device in position pass after pass.

x. 5 & Prime; Installment Because the magnet
on the Dragy box appeared to be instead strong, we chose to toss the system on the roofing system of Luke’s Mustang as opposed to on the inside. And while the placement doesn’t appear to matter for efficiency, we wished to see if it would hold on during a launch. And also, the blinking blue LED light in addition to package highlighted the Rapid and Furious in us –– well, the very first movie and not the atrocity of the most recent, anyway. We also made use of a cellular phone install which we bought at Five Listed below for only $5.00. The place had a suction cup on the base, which we placed on the traveler side of the windshield so it wouldn’t be in the chauffeur s view
. For video functions, we additionally used a cellular phone place which we purchased Five Listed below for just $5.00. The install had a suction cup on the base, which we mounted on the guest side of the windscreen so it wouldn’t remain in the chauffeur s view.
At the Strip
As we struck the hosting lanes, we activated the Dragy and synced it with the app. This process just took a few seconds, and we prepared to go. Luke was competing in the 6.0-index course however had not done any type of prior screening to make certain the cars and truck was on point. So as he inspected 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 quicker than 6.0-seconds for the class –– Luke placed an A-to-B tune-up in the auto. While he was pushing buttons on the laptop computer we safeguarded the cellular phone in the install and changed the view for the video. When we were next in line for the fatigue, we struck document and let the Dragy go to function. We didn’t recognize if the system would certainly begin data logging as soon as the auto moved, which it does. Nevertheless, after the pass, you can uncheck the things not wanted, and the video clip overlay will show the chosen info.
Setting up the Dragy only takes a couple of mins considering that the app is easy to navigate. You can additionally alter the efficiency mode, check the leader board, and take a look at the tempeture, thickness altitude (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 after that continued to stage the cars and truck. After that, as the Xmas tree lit up, he let go of the transbrake and the Dragy mosted likely 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 data showed a 6.43 in the 1/8-mile at 81 miles per hour. 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 dispersed to the racer. Nevertheless, it was obvious that the Dragy was close, with a distinction of only.02-seconds from the boards.
For the second pass, Luke made some changes to the auto 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 wondered to see if the Dragy would certainly react the exact same. Luke took care of to run a quicker e.t. this round, at 6.39-seconds. Again, 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 revealed that the power was ramped in quicker than before with a faster e.t. and far better mph.
Luke Thompson makes a hit in his turbocharged Mustang with the Dragy installed on the roof covering of the car.
Back In The Pits
After making a couple of hits with the cars and truck, we went back to the pits to check out the application. It’s straightforward to utilize and offers a great deal of functions. You can establish a garage for your various autos, view background, and it also has a leaderboard that will certainly allow you know where your times stand all throughout the globe. Our preferred function is the video clip overlay that automatically includes information to the pass. This info can conveniently be cut right from your device so you can share it on social media or the leader board.
The Dragy’s video overlay is seamless. You can even trim the video in the app prior to submitting it to social networks or the leader board.
In general, we were really satisfied with the Dragy. The unit is very easy to set up and use, the app is easy to use, and you can figure whatever out in just a minute or 2 by scrolling around. Yet above all, the gadget is sensitive sufficient that when you make a horsepower modification to the cars and truck, it will register, which indicates we don’t have to trust the seat of our trousers anymore. In the future, we will be able to utilize our Dragy to examine components and see if they are an enhancement or otherwise. The only problem is determining exactly how to obtain our project off the jackstands to examination. Yet that’s a different tale for another day.
We wanted to say thanks to Luke for letting us get in his way at Brawl in the Falls and crawl all over his Mustang. Additionally wished to give thanks to NXGonzo, Chris Raska of Wichita Raceway Park, and Matt Plotkin for putting on a wonderful occasion.
