In 2005 Ford (USA) released the fifth-generation Mustang to huge fan-fare. Finally Ford had taken the Mustang back to its roots with design and styling that strongly resembled the original first and second generation (pre-foxbody) cars. Ford also, despite a world of ever-more stringent emissions regulations, stood strong and made sure these new Mustangs were equipped with snorting, naturally aspirated V8’s, and remained rear-wheel-drive.
The fifth-generation Mustangs were such a strong base to work from, they were almost immediately picked up by various tuning companies who put their own spin on the car (usually involving adding MUCH more power) and existed to satisfy customers who wanted that little bit more! One of these companies is Roush.
Roush was formed in 1995 as an automotive tuning company. They’ve always specialised in aftermarket performance parts for Fords. So strong is the partnership between Ford and Roush, that Roush-tuned Fords are usually sold through select Ford dealerships. Roush are best-known for bolting their own superchargers onto Mustangs. They first did this with the 360R in 2002 – using the fourth-generation Mustang.
In 2007, they got their hands on the fifth-generation Mustang and created the formidable 427R. With the 427R they took the factory-standard 4.6 litre V8, and added a (yes, you guessed it) supercharger to it. This supercharger is called the “Black Eaton M90 Supercharger” and is developed in-house by Roush.
Along with adding a supercharger, Roush also upgraded with engine with special intake manifolds, intercooler & radiator, air induction system, and a calibrated ECU. Customers would also find underneath the car a full custom exhaust system, uprated suspension, bigger brakes, and a tweaked chassis. All of these modifications put together gave the 427R a whopping 435bhp, and 400 lb-ft of torque. These cars are not only incredible performance machines, they’re also rare with only around 50 made.
With so few of these cars made, we couldn’t miss an opportunity to feature one on the website when we saw some videos of Brian smoking around in this snarling beast of a Mustang. The crazy thing about Brian’s Roush 427R though? Well it turns out even 435bhp is not enough… this one’s got 500bhp courtesy of some further modifications to the engine.

Interview with the owner
- Wow Brian, this thing's a bit of a handful we imagine – when did you buy it?I bought it in January 2020!
- What made you buy a Mustang?I always wanted a muscle car since I was able to drive!
- What's it like to drive?Absolutely awesome once you get used to left hand drive. It's hugely powerful, sounds incredible and constantly wants to light up the rear wheels, wet or dry!
- And you mentioned the car is running EVEN more than the standard 435bhp offered by Roush?Yes, it's actually running closer to 500bhp, and 600nm (440 lb-ft) torque.
- So what did you do to the engine to achieve this?It wasn't actually me, it was the previous owner. He took the engine and made it fully forged – pistons, conrods, you name it. Not sure how much it cost, but the performance is incredible.
- Do you plan to do any further modifications to it?No, it's enough of a handful as it is!
- Is the car a "keeper" or will you sell it one day?I'll take it to my grave
- Ok final question – ignoring cost, and assuming you couldn’t go and sell it for profit… what’s your dream car and why?Well this is really my dream car, but I'm also looking to build a 1953 ford F100 pickup as that's another dream car for me.
