Roush’s new 810bhp Mustang supercharger kit gives it GTD-spec power for $10k

Roush is no stranger to pumping up the Ford Mustang to brave new heights, and now it has revealed a very brave, very high height. For its new supercharger bolted onto the Mustang GT V8 helps it punch out a massive 810bhp.

That’s around the same as the limited-edition, GT3 RS-baiting Ford Mustang GTD, though you’d stand a better chance of seeing a lightweight Range Rover than ever getting one of those $325k+ track monsters. (As of May 2024, over 7,500 people applied for one... from a limited run of just 1,000 cars.) 

The GTD of course, isn’t just a power car, because there’s a tonne (not literally) of aero trickery at play. Roush swings for the rafters with its engine-only upgrade, courtesy of a dual-throttle body kit. So, there’s an inverted Eaton TVS R2650 supercharger with a front inlet, dual intercoolers and an 84mm pulley.

That maintains 13psi at 7,000rpm – reusing Ford’s original 80mm throttle bodies and induction bits – to produce that headline horsepower figure and 630lb ft of torque.

Other bits that contribute include a large heat exchanger, a Bosch intercooler pump, new injectors and fuel rails, and... sparkier? Yes, sparkier Ford Performance spark plugs.

Prices? The 'Launch Edition' - that comes bearing Jack Roush's signature, no less - starts from $9,995, which feels like fairly exceptional value next to one of those $325k+ track monsters.
