It’s hard to imagine Steve Saleen’s performance shop has been around for 25 years, but the company today is celebrating the milestone with the launch of the SA-25 Sterling Edition Ford Mustang. The car is based on the uprated S302 Extreme edition pony car, which means it’s packing a 620hp twin-screw supercharged V8 engine with more than 600ft-lb of torque. To ensure all that power is delivered reliably, engineers added a host of performance upgrades.

The list includes a forged crankshaft, forged connecting rods, individually blueprinted forged pistons, 5 axis CNC aluminum cylinder heads, high flow fuel injectors, and a set of high performance camshafts. The mega engine is then mated to a short throw, 6-speed manual transmission and Max-grip rear differential, which sees the Extreme edition reach 60mph in less than four seconds and clicks through the quarter mile in just under 12 seconds.

To get that kind of performance, the team had to get the S302E’s power to the ground. This is accomplished with standard 20in, five-spoke forged aluminum alloy wheels wrapped in Pirelli P-Zero Rosso tires. Handling is improved with Saleen’s Racecraft suspension set-up and brake package. The performance brake system features 15in vented, slotted rotors with 6-pistons calipers in the front and 11.8in rear vented discs with single piston calipers in the rear.

If all this sounds like something you’d like to see sitting in your garage then you’d better be prepared to front the $100,000 asking price.
