Dragy Evaluation: We Put The GPS Efficiency Meter To The Test

Back in the olden days, when measuring a vehicle’s efficiency, we utilized the seat of our pants– claiming that makes me feel truly old. Considering that we didn’t have a chassis dyno or any kind of fancy electronic gadgets to measure performance, we had to improvise well, kind of. We would generally make changes to our automobiles with high-performance parts like sticky tires, camshaft, exhaust, and nitrous, among others. After that, after the installation, we would strike the streets to see if the lorry felt any kind of faster. If it did, which was 99-percent of the time because we didn’t want to confess the parts slowed down the cars and truck down, we were happy. Naturally, the method of efficiency testing was really unrefined and highly imprecise.

The Dragy GPS Performance Meter takes the uncertainty out of adjusting and brand-new modifications.

The issue during this period was that there were only a couple of means to determine included performance: on an engine dyno or at the track. Regrettably, our neighborhood track closed down for some time to make issues worse, which suggested we needed to travel an hour north to test and tune.you can find more here dragy review from Our Articles That was the only alternative we had at the time. Nevertheless, this is not the case in this day and age. Also in most towns, you can locate a chassis dyno to wheel your cars and truck and see if a brand-new product makes a difference. Today there are other high tech approaches that gauge efficiency, like a general practitioner performance meter.

The Dragy

Among the extra popular gadgets frequently filling our social media sites feed is the Dragy GPS Performance Meter. And while we understand that a great deal of you have experience with this item, we have yet to test the unit ourselves, and decided to do just that. For our test, we connected to a good friend of ours, Luke Thompson, proprietor of Mike’s Lube Store and an enthusiastic drag racer. For the examination, Thompson fulfilled us out at Wichita Raceway Park in Wichita Falls, Texas, where the Brawl in the Loss 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 metal plates with glue for mounting, and a billing cable.

The Dragy is a pretty easy tool on the outside. It’s nothing more than a little black box that’s 1-inch vast, 3-inches long, and 1/2-inch high. The gadget has a magnet under and features 2 metal plates with an adhesive that can be mounted on the vehicle’s inside. It also consists of a charging cord; however, you will need to offer a power supply. The only other point required to make this gadget work is the Dragy App, which can be downloaded from the Apple Application Store for an iphone gadget or the Google Play Shop for an Android. After we filled the application on the iPhone, charged the Dragy, and upgraded the software application, we prepared to do some testing.

Just how It Works

The Dragy is easy to use and establish. The unit utilizes high-speed GPS satellites and afterwards determines your automobile’s performance within 1/100th of a 2nd. The software program will tape-record the pass prior to keeping it on your gadget. You can also select the specifications you intend to test, including 0-30 miles per hour, 0-60 miles per hour, 60-130 miles per hour,1/ 8-mile, 1/4-mile, and 1/2-mile, among others. And if that’s insufficient, you can additionally make use of the custom-made mode and include even more settings, which we did, like 60-foot time, 330-foot times, or any others you might require.

While you can mount the Dragy on the car’s interior, we made a decision to toss it on the roofing. The magnetic base was solid sufficient to hold the unit in position pass after pass.

on the Dragy box appeared to be instead strong, we decided to toss the device on the roofing of Luke’s Mustang rather than on the inside. And while the positioning doesn’t seem to matter for efficiency, we intended to see if it would hold on throughout a launch. Plus, the blinking blue LED light on top of package drew out the Quick and Furious in us –– well, the initial flick and not the wrong of one of the most recent, anyway. We additionally used a cellular phone mount which we purchased 5 Listed below for just $5.00.

. For video clip objectives, we additionally used a cellular phone install which we bought at 5 Listed below for only $5.00. The mount had a suction mug on the base, which we placed on the guest side of the windshield so it wouldn’t remain in the chauffeur s line of sight.

At the Strip

As we hit the staging lanes, we switched on the Dragy and synced it with the app. This process just took a few secs, and we were ready to go. Luke was racing in the 6.0-index class yet had refrained from doing any kind of previous screening to ensure the vehicle got on point. So as he checked 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 placed an A-to-B tune-up in the vehicle. While he was button on the laptop we protected the cell phone in the install and changed the view for the video clip. When we were next in line for the burnout, we hit record and let the Dragy go to work. We didn’t know if the system would begin data logging as quickly as the car relocated, which it does. Nevertheless, after the pass, you can uncheck the things not wanted, and the video clip overlay will certainly present the chosen information.

Establishing the Dragy only takes a few minutes given that the application is simple to browse. You can likewise transform the performance mode, inspect the leader board, and consider the tempeture, thickness altitude (DA), along with a host of other attributes.

Making Passes

Luke lit the tires up in the water box on the Mustang and after that proceeded to stage the automobile. Then, as the Xmas tree brightened, he let go of 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 information displayed a 6.43 in the 1/8-mile at 81 mph. However we couldn’t contrast all of the information from the Dragy to the timeslip considering that this was a no-prep race –– no slips were being distributed to the racer. Nevertheless, it was obvious that the Dragy was close, with a difference of only.02-seconds from the boards.

For the second pass, Luke made some adjustments to the car 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 react the same. Luke handled to run a quicker e.t. this round, at 6.39-seconds. Once more, the Dragy presented a 6.35, this time around at 89.30 mph. 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 previously with a faster e.t. and better mph.

Luke Thompson makes a hit in his turbocharged Mustang with the Dragy placed on the roof covering of the cars and truck.

Back In The Pits

After making a number of hits with the cars and truck, we returned to the pits to check out the application. It’s easy to utilize and supplies a great deal of attributes. You can establish a garage for your various vehicles, view history, and it even has a leaderboard that will let you know where your times stand all across the world. Our favored feature is the video overlay that instantly adds information to the pass. This info can easily be cut right from your device so you can share it on social media or the leader board.

The Dragy’s video clip overlay is seamless. You can also cut the video clip in the app before uploading it to social networks or the leader board.

In general, we were very pleased with the Dragy. The system is simple to set up and make use of, the application is user-friendly, and you can figure whatever out in simply a min or 2 by scrolling about. However most of all, the device is sensitive sufficient that when you make a horse power change to the auto, it will sign up, which indicates we put on’t need to trust the seat of our pants any longer. In the future, we will be able to utilize our Dragy to evaluate components and see if they are a renovation or not. The only trouble is figuring out just how to get our project off the jackstands to test. Yet that’s a various tale for another day.

We intended to give thanks to Luke for letting us get in his method at Quarrel in the Falls and crawl all over his Mustang. Additionally wanted to say thanks to NXGonzo, Chris Raska of Wichita Raceway Park, and Matt Plotkin for placing on a terrific occasion.
