Back in the olden days, when gauging a lorry’s performance, we made use of the seat of our pants– claiming that makes me really feel actually old. Since we didn’t have a framework dyno or any type of elegant digital devices to measure efficiency, we needed to improvise well, type of. We would primarily make changes to our vehicles with high-performance components like sticky tires, camshaft, exhaust, and nitrous, among others. After that, after the installation, we would certainly hit the streets to see if the lorry felt any much faster. If it did, which was 99-percent of the time due to the fact that we didn’t intend to admit the parts slowed down the cars and truck down, we enjoyed. Obviously, the technique of performance screening was extremely unrefined and extremely inaccurate.
The Dragy GPS Efficiency Meter takes the guesswork out of adjusting and new adjustments.
The Dragy
One of the more preferred gadgets continuously 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 test the system ourselves, and decided to do simply that. For our test, we reached out to a friend of ours, Luke Thompson, proprietor of Mike’s Lube Store and a serious drag racer. For the test, Thompson met us out at Wichita Raceway Park in Wichita Falls, Texas, where the Quarrel 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 goodies.
The package includes a Dragy with a magnetic base, 2 steel plates with glue for installing, and a billing cable.
The Dragy is a pretty straightforward gadget outside. It’s nothing more 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 comes with 2 steel plates with an adhesive that can be placed on the vehicle’s interior. It also includes a charging cord; nonetheless, you will require to supply a power supply. The only other thing called for to make this tool work is the Dragy Application, which can be downloaded and install from the Apple Application Shop for an iphone tool or the Google Play Store for an Android. After we packed the application on the apple iphone, charged the Dragy, and upgraded the software program, we were ready to do some screening.
Just how It Functions
The Dragy is easy to use and establish. The unit employs high-speed GPS satellites and after that gauges your lorry’s performance within 1/100th of a second. The software will record the pass prior to saving it on your device. You can additionally pick the parameters you want to examine, including 0-30 mph, 0-60 mph, 60-130 mph,1/ 8-mile, 1/4-mile, and 1/2-mile, among others. And if that’s not enough, you can likewise utilize the customized mode and include more settings, which we did, like 60-foot time, 330-foot times, or any others you may need.
While you can mount the Dragy on the automobile’s indoor, we determined to throw it on the roofing system. The magnetic base was solid enough to hold the unit in place pass after pass.

on the Dragy box seemed to be rather strong, we decided to throw the system on the roof of Luke’s Mustang instead of on the inside. And while the placement doesn’t appear to matter for performance, we wished to see if it would certainly 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 very first movie and not the wrong of the most recent, anyhow. We also used a cellular phone install which we bought at Five Listed below for only $5.00. The install had a suction cup on the base, which we placed on the passenger side of the windshield so it wouldn’t be in the motorist s line of vision
. For video functions, we likewise made use of a mobile phone place which we purchased Five Listed below for only $5.00. The place had a suction mug on the base, which we placed on the traveler side of the windscreen so it wouldn’t be in the driver s view.
At the Strip
As we hit the staging lanes, we switched on the Dragy and synced it with the app. This procedure only took a couple of secs, and we prepared to go. Luke was competing in the 6.0-index class but had not done any type of prior testing to make sure 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 Autumns was a no-prep race, and he couldn’t go much faster than 6.0-seconds for the class –– Luke put an A-to-B tune-up in the automobile. While he was pushing buttons on the laptop we secured the cellular phone in the mount and readjusted the sight for the video clip. Once we were next in line for the fatigue, we hit document and let the Dragy most likely to work. We didn’t understand if the unit would 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 show the selected info.
Setting up the Dragy just takes a couple of minutes considering that the application is easy to browse. You can additionally change the performance setting, examine the leader board, and consider the tempeture, density elevation (DA), together with a host of other functions.
Making Passes
Luke lit the tires up in the water box on the Mustang and afterwards continued to present the automobile. Then, as the Christmas tree illuminated, he let go of the transbrake and the Dragy went to work. The car 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. Regrettably 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 evident that the Dragy was close, with a distinction of only.02-seconds from the boards.
For the second pass, Luke made some adjustments 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 react the very same. Luke handled to run a quicker e.t. this round, at 6.39-seconds. Again, the Dragy showed a 6.35, this moment at 89.30 miles per hour. 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 previously 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 of the auto.
Back In The Pits
After making a couple of hits with the automobile, we went back to the pits to discover the app. It’s basic to use and uses a great deal of features. You can set up a garage for your various autos, sight background, and it also has a leaderboard that will let you know where your times stand all across the globe. Our favored attribute is the video overlay that automatically adds data to the pass. This information can quickly be cut right from your tool so you can share it on social media sites or the leader board.
The Dragy’s video overlay is smooth. You can even cut the video clip in the app prior to submitting it to social networks or the leader board.
On the whole, we were extremely amazed with the Dragy. The unit is very easy to establish and utilize, the application is easy to use, and you can figure whatever out in simply a min or 2 by scrolling about. Yet above all, the device is sensitive sufficient that when you make a horse power adjustment to the automobile, it will register, which indicates we don’t need to trust the seat of our trousers anymore. In the future, we will certainly be able to use our Dragy to check components and see if they are an enhancement or not. The only trouble is finding out exactly how to get our job off the jackstands to test. However that’s a various tale for another day.
We wanted to thank Luke for letting us enter his means at Quarrel in the Autumns and crawl all over his Mustang. Also wanted to thank NXGonzo, Chris Raska of Wichita Raceway Park, and Matt Plotkin for placing on a terrific event.
