Vortech Supercharged 2015 Mustang GT Is A Test Vehicle Turned Daily

Have you ever thought about how aftermarket performance parts get developed? It’s not often aftermarket companies get access to the latest OEM platforms before its market availability, which means many aftermarket companies have to wait to get their hands on the new vehicle just like everyone else. 

Once the part is developed and on the market, what happens to the car that was used to create it? Sometimes the vehicle belongs to someone in the company, a friend or family member, but once in a while, someone can be in the right place at the right time, much like Jose Flores was when he bought his 2015 Mustang GT directly from Vortech Superchargers. 

According to Flores, a sales rep at Vortech, this particular S550 was purchased in 2014 as a Vortech test vehicle. It was used to develop the 50-state emissions legal Vortech V-3 Si-Trim System and played a role in developing Borla Exhaust systems for the then-new S550 platform as well. 

“The car was basically brand-new when I bought it,” Flores said. “It had a few miles on it, but other than being used for development and being taken to a few events for promotion, the car stayed safely inside Vortech’s engineering department.” That is until he began using it as a daily driver. 

Of course, the car came with the Vortech V-3 Si-Trim System it was used to develop, and it came with the Borla exhaust it helped create for the S550. 

According to Vortech marketing materials, the complete system boosts a stock 5.0-liter GT Mustang to 630 hp and 483 lb-ft of torque with 7.5 to 8.5 psi from the intercooled V-3 Si supercharger system at factory redline. The complete bolt-on system comes with all the necessary belts, pulleys, and fasteners. 

The V-3 Si-Trim supercharger features a 78-percent isentropic efficient compressor for cooler, denser air and reduced parasitic drive losses. Vortech uses a suite of design and analysis software tools to create advanced centrifugal compressor stages. Performance quantification and further development occur with the use of an SAE J1723 compliant test cell. 

Flores said that over his two years of ownership, the car has significantly evolved. “It has been progressively changing since I got the car. 

“I was already a fan of the S550 Mustangs and the very potent Coyote 5.0-liter engines, especially when supercharged,” Flores said. He found the color was very appealing and it has become one of his favorite aspects of the car, noting “the Competition Orange is a striking color, but not a very common color.” 

The supercharged Gen II Coyote powering the S550 mates to an MT82 transmission with its stock 3.73 Torsen differential and a McLeod RXT Clutch. Flores has upgraded the car with Koni shocks, Eibach springs, Whiteline sway bars, and UPR suspension components. However, it retains its factory 15-inch performance pack Brembo brakes with Hawk ceramic pads. 

Except for Velgen Split5 20×9, 20×10.5 wheels wrapped in Nitto NT555 G2 tires for the street and Fifteen52 Formula GT wheels for the track covered in Toyo R888R tires, Flores says “the car is still stock from the outside as I cannot decide which route I want to go.” 

Flores shared that he has performed all of the work himself except the supercharger and an alignment. 

“I love working on cars, anytime I can get my hands on one I am happy.” Flores also built and still currently owns a 1992 Ford Mustang, 1969 Oldsmobile 442, and a 1971 Datsun 510. 

The best part of the S550 build? According to Flores, it’s “working on a new car without grease everywhere, it’s an amazing thing.” He added that he also enjoys the way it handles and its smog-legal 630 horsepower. 

Plans for this daily driver include a Tremec Magnum T-56, upgraded axles, aluminum driveshaft, more boost, “and possibly some exterior modifications.” 

Jose would like to give special thanks to: Brian Ellis and Jimmy Martz at Vortech Superchargers, Scott, Anthony, and Ray at Velgen Wheels, Sharad at UPR Products.
