Roush has been on top of the supercharger game now for some time. Their M-90 based superchargers have been the backbone of their hot Roush Mustang and F-150’s since 2001. And in 2008 they introduced their new top dog TVS 2300 supercharger, pushing the horsepower envelope well past 500hp from a 4.6 liter Mustang engine.

To continue expanding their offerings, Roush has announced their new Phased R2300 ROUSHcharger. The new offerings replace the previous TVS 2300 packages and offer three levels from wild, to wilder, to wildest. The concept is that owners can buy in at the Phase 1 level and upgrade as they choose to Phase 2 and Phase 3

“The concept of being able to start at one level and over time increase the horsepower and torque is really unique in the automotive world, and something that I see as becoming very popular with Mustang owners,” said Jack Roush. “It used to be that when you chose a supercharger you were pretty much stuck with what you got, but these new Phased ROUSHchargers allow for a relatively simple upgrade process which offers major increases in horsepower.”

The new Phased R2300 ROUSHchargers are first being offered for the 2005-2010 Mustangs in both single-belt and dual-belt configurations. The choice between the single- or dual-belt configuration allows you to opt for the secondary sheave FEAD system that makes for a lot better drivability and engine longevity in the high horsepower levels. With the dual-belt system the supercharger is isolated from the other engine accessories, with a dedicated belt for the supercharger. This allows for a reduced belt length and the overall system inertia and demands on the belt tensioner is also greatly reduced.

The base Phase 1 R2300 ROUSHcharger starts at 475 horsepower (435 lb.-ft. torque) and has a suggested retail price of $5799.00 or $6999.00 with the dual belt upgrade. This comes in slightly lower in tune than the previous one size fits all TVS 2300 ROUSHcharger. This system can be put on the 2005-2010 Mustang GT 4.6 3V without the absulote necessity of upgrading the engine to forged internals. Roush however suggests that there is still a risk to the stock engine depending on tune and driving conditions. And this system will void the factory Ford warranty.

The Phase 2 R2300 ROUSHcharger model jumps to 550 horsepower (500 lb.-ft. torque) and retails at $6699.00 with the dual belt version costing. $7499.00. Both the Phase 1 and Phase 2 packages come with a 90-day parts-only warranty.

For those wanting the most under the hood, the Phase 3 R2300 ROUSHcharger will push out 625 horsepower (565 lb.-ft. torque) and retail at $12,999.00. The package comes standard with the dual-belt configuration and includes forged internal engine upgrade components. This package also is the only one of the three that comes with a 3-year/36,000 mile warranty from the vehicle’s original in-service date, or 12-months/12,000 miles on cars already past this mark. In order to qualify for the Phase 3 warranty, the kit must be installed by a certified Ford automotive technician or automotive service technician certified by the Institute for Automotive Service Excellence (ASE).

Roush has long been recognized as the leader in Mustang Powertrain development, not only for the development of the hard parts, but even more importantly from the engine calibration. Their team works on calibrations for many OEM-vehicles and has a level of experience that is virtually second to none in the industry. This is a prime factor in why the ROUSHcharger tends to run smoother and generate power through the entire curve.

All three packages of the R2300 ROUSHchargers come with a Roush calibration, air-to-water intercooler. The kits are expected to begin shipping in mid-June.
