The 2008 Srt8 Challenger marked the return of a legendary nameplate, injecting raw American muscle and formidable performance into the modern era. This initial year model of the reborn Challenger was exclusively the high-performance SRT8 variant, making a bold statement right from the start. For enthusiasts seeking a potent blend of retro styling and contemporary power, the 08 SRT8 Challenger stands out as a compelling option, especially in the used car market. Let’s delve into what makes this car a true performance icon.
The heart of the 08 SRT8 Challenger is its monstrous 6.1-liter HEMI V8 engine. This naturally aspirated powerhouse churns out a staggering 425 horsepower at 6,200 RPM and 420 lb-ft of torque at 4,800 RPM. The engine block is constructed from robust iron with reinforced bulkheads, ensuring durability under high stress. It features ported HEMI heads with a large cross-sectional area, optimizing airflow for maximum power. The OHV 2-valve per cylinder configuration with chain drive, a 4.06-inch bore, and a 3.58-inch stroke contribute to its impressive performance characteristics. A high 10.3:1 compression ratio, along with 2.08-inch intake and 1.60-inch exhaust valves – the intake valves being sodium-filled and hollow-stem – further enhance engine efficiency and output. Electronic Sequential Port Fuel Injection ensures precise fuel delivery, while cast eutectic high-load flat-top alloy pistons and piston oil cooling jets manage heat and friction effectively. Powder metal high strength connecting rods and a forged micro-alloy steel crankshaft with tri-metal main bearings ensure the engine’s bottom end is as robust as the top. The billet steel high-strength camshaft, cast aluminum intake manifold with core-dipped runners, high flow capacity fuel injectors, windage tray, and shorty clamshell exhaust headers all work in concert to deliver exhilarating performance.
Power from the potent HEMI is channeled through a robust drivetrain, offering a choice between a 5-speed Getrag automatic transmission or a 6-speed Tremec manual transmission, catering to different driving preferences. A 3.06:1 final drive ratio maximizes acceleration, while the Sure-Grip anti-lock differential and anti-spin rear differential ensure optimal traction, especially when putting down power. Electronic Stability Program and Brake Assist enhance control and safety, complemented by All-Speed Traction Control.
Braking performance is equally critical for a car of this caliber, and the 08 SRT8 Challenger does not disappoint. It features a high-performance Brembo brake system, renowned for its stopping power and fade resistance. The front brakes consist of massive 14.2-inch vented and slotted discs clamped by 4-piston fixed calipers, while the rear utilizes 13.8-inch vented and slotted discs. Vacuum-assisted ABS further enhances braking confidence in all conditions.
The 08 SRT8 Challenger rides on Alcoa forged alloy 20” x 9” wheels, wrapped in Goodyear Eagle RSA 245/45/ZR20 tires. This wheel and tire combination provides a good balance of grip and ride quality, while also contributing to the car’s aggressive stance.
The steering and suspension systems are tuned for performance driving. The rack and pinion steering with hydraulic assist offers a responsive 2.7 turns lock to lock. The suspension setup features upper and lower A-arms, coil springs, and Bilstein tube shocks at the front, and a multi-link rear suspension with coil springs and Bilstein tube shocks. Anti-roll bars, measuring 30mm at the front and 16mm at the rear, help to minimize body roll during cornering, contributing to the car’s surprisingly agile handling for its size.
The exhaust system of the 08 SRT8 Challenger is designed not only for performance but also for auditory pleasure. It features 2.75-inch diameter exhaust pipes with chrome tips, a high-flow muffler, and two resonators. This combination delivers a deep, throaty exhaust note that is unmistakably American muscle.
In terms of outright performance, the 08 SRT8 Challenger delivers impressive figures. It can sprint from 0-60 mph in just 4.7 seconds and complete the quarter-mile in around 13.0 seconds at 109.7 mph. The top speed is electronically limited to 170 mph. It can achieve .85g of lateral acceleration and navigate a slalom at 65.0 mph. Braking from 60-0 mph is achieved in a short 110 feet, and 80-0 mph in 212 feet, further demonstrating the effectiveness of the Brembo brakes.
While generally robust, it’s worth noting a few technical service bulletins and recalls that applied to early Challengers, including potential issues with battery cables, driveability reflashes, and key fobs. Additionally, like many vehicles of the era, there was a recall related to Tanaka airbag inflators. Prospective buyers of a used 08 SRT8 Challenger should check vehicle history reports and inquire at a dealership to ensure any necessary services or recalls have been addressed. For more detailed information, resources like the ChallengerTalk forum (Technical Service Bulletins & Recalls – Dodge Challenger Forum: Challenger & SRT8 Forums) offer valuable community knowledge and insights.
In conclusion, the 08 SRT8 Challenger is a significant vehicle that successfully revived the Challenger nameplate with a potent combination of retro styling and modern performance. Its powerful 6.1L HEMI engine, performance-tuned chassis, and aggressive looks make it a desirable muscle car for enthusiasts. If you’re in the market for a used performance car with iconic styling and exhilarating power, the 08 SRT8 Challenger is definitely worth considering, provided it has been well-maintained and any outstanding recalls or service bulletins have been addressed.
