You have to envy the crew at Latemodel Restoration, they have not one, but two 2015 Mustang project cars. The other project ’Stang is a Guard-hued GT upgraded with a host of mods, including a Roush Phase 1 supercharger. It put down 546 horsepower and 496 lb-ft of torque to the rear wheels. However, being in the business of selling upgrades, it behooves the Latemodel team to have experience with as many combos as possible, and for the company’s Triple Yellow 2015 GT, the team chose to add one of Hellion Power Systems’ Eliminator turbo systems.
“Dare to be different,” Jonathan McDonald, Marketing/Research rep at Late Model Restoration, said. “TVS and centrifugal blowers are all over the place. Pull up to Cars & Coffee with a set of twins under the hood and you’re the only one; not to mention the massive power potential with good gas and a few button pushes on the boost controller. Plus we’ve already done a TVS 2015 and wanted to go a route we hadn’t been down before.”
Up until now, the Latemodel team worked over its yellow project with some of the basic bolt-ons we all know and love. They started with a JLT Performance cold-air intake, a Bassani mid-muffler cat-back, Eibach lowering springs, and a set of gorgeous DF5 wheels. They also tweaked its appearance with hood struts and a set of Roush hood scoops. In deference to the car’s new upgrade, they first swapped out the first Bassani system for one of the company’s 3-inch cat-backs, so the exhaust could handle all the additional airflow.
If you need a refresher on Hellion’s potent twin-turbo systems for the latest Mustang, you can flash back to our previous coverage. In short, the Hellion kit mounts two Precision turbos in front of the new-school Coyote engine using Hellion-design hot- and cold-side piping bent up by Bassani exhaust. The system allows you to opt for either 55 or 62mm turbos and it includes two TurboSmart VeePort blow-off valves, and two Turbosmart 40mm wastegates.
Here’s a look at how the project got started…
“I would say difficulty would be a five out of 10 with the most difficult part being the wrapping of wires and components such as hoses and the steering rack. Most of the install is straight forward and goes very smoothly,” Jonathan explained. “We did take extra time and purchased extra heat wrap to protect a few harnesses that were not called for as this is a tuner kit and felt a need to take extra precautions. All the mounting and trimming called for were minimal and the finished product looks as if it could have been a factory option.”
For big hit of streetable power, Late Model choose the 55mm turbos, which as we have already learned, are quite potent. They also added an optional Turbosmart’s E-Boost 2 boost controller, so the adjustment of the boost from those 55s is available right in the cockpit. And, to feed the turbocharged Coyote, they swapped out the stock injectors in favor of an octet of Injector Dynamics 1,000cc squirters.
With the new Hellion combo in place and a custom tune from Late Model’s SVE Custom tuning division, the Triple Yellow GT responded with over 700 horsepower and over 600 lb-ft of torque at the rear wheels. That’s definitely enough to get your attention, and for this beautiful S550 to back up its good looks with awesome performance.
“…The car drives like stock under ‘normal’ conditions and turns in to a monster when you press the pedal,” Jonathan said. “The S550 chassis is quite controllable and predictable, so harnessing the added power on the pavement isn’t as ‘white knuckle’ as it has been for Mustangs past.”
