As if it was born for boost, the Gen 3 Coyote 5.0-liter engine under the hood of the 2018 Mustang GT delivers the goods when the psi starts pumping. With the advent of the latest Mustangs, Roush Performance updated its superchargers with Eaton’s latest 2.65-liter rotor pack for increased efficiency and performance.

We chose the Roush blower because we have had such good results with the 2300 in the past. — Matt Alderman, ID Motorsports

The standard kits come complete with everything you need to install them, right down to the companion calibration. However, those complete systems were designed to keep things safely within the parameters of the Roush warranty. However, there are always those willing to push the performance envelope.

“We chose the Roush blower because we have had such good results with the 2300 in the past,” Matt Alderman, of ID Motorsports, said. “When we saw the new design we couldn’t wait to get our hands on it.”

Before he could start custom-tuning the Roush TVS R2650 blower on the ID Motorsports’ 2018 Mustang GT, Matt Alderman needed to install the system. He had experience with the previous system on 2015-2017 cars, so the install was straightforward. He removed the factory fascia and induction and bolted on the supercharger.

Once he did, Matt was quick to install the new 2018 ROUSH Mustang Supercharger Kit (PN 422090; $7,699.99) on the company’s in-house 2018 Mustang GT project vehicle. Having previous experience with Roush’s previous 2.3-liter TVS unit, Matt immediately saw the improvements from the bigger more efficient unit.

“We definitely noticed some differences with the new design,” Matt explained. “With the new heat exchanger, we have seen less air-temp rise than with the 2300. Even in the Florida heat we have only seen an average increase of 7 degrees in downstream air temp. We also noticed the increased airflow from the new front-feed case.”

Developed in conjunction with Ford Performance, the Roush TVS 2650 looks right at home atop the dual-fuel Gen 3 Coyote. While he didn’t use the Roush calibration, Matt installed all the hardware as-delivered.

The improved efficiency is great, but to make the most of it, Matt created a custom calibration.

“When dealing with a calibration from a manufacturer such as Roush, the ‘canned tune’ has to account for so many variables,” Matt explained. “It is a very stout calibration out of the box but with a custom tune we can support a few more mods and tighten up the window of the intended use of the vehicle more specific to the customer needs.”

TVS R2650 Phase 1 Supercharger System Features

• Eaton’s R2650 rotating assembly w/ new high-flow front inlet and outlet ports

• Supercharger rotors feature 170 degrees of twist (vs. 160 degrees on previous R2300)

• New 2650 rotor geometry with better sealing and optimized length-over-depth ratio

• Increased durability thanks to bigger bearings and thicker timing gears

• Pressure relief ports in bearing plate for reduced input power

• All-aluminum, high-efficiency intercooler and full-face radiator w/ high-capacity degas bottle and separate reservoir provides

• Roush-designed upper and lower aluminum intake manifolds

• High-flow induction system w/ larger throttle body provides increased airflow

• Heavy-duty, first sheave FEAD system reduces stress on the engine

To do so, Matt turned to his trusty SCT Performance hardware and software. A skilled calibrator, Matt used these tools to fine tune the 2.65-liter TVS/Gen 3 Coyote combo.

“We were the first to custom-tune the Roush 2650 using SCT and still retaining the MAP sensor but not using the MAF as Roush does,” Matt said. “We like using SCT because we can get all of the data needed when calibrating for a new platform. They are also quick at supporting the new parameters we need.”

Adding the RoushCharger 2650 TVS and a custom ID Motorsports/SCT calibration delivered 663.62 horsepower and 552.05 lb-ft of torque at the rear wheels, which accounted for peak-to-peak gains of 267.37 horsepower and 200.74 lb-ft of torque.

After working his magic with those parameters, Matt’s Mustang responded nicely. Rear-wheel output jumped from 396.25 horsepower and 351.31 lb-ft of torque to 663.62 horsepower and 552.05 lb-ft.

“We have a whole list of tests we have lined up for this project,” he added. “Next up will be race gas, high-pressure fuel pump, direct injectors, and E85 to name a few.”

Sounds like a lot more power is coming from this boosted Gen 3 Coyote, so stay tuned.
