While the new SRT Viper is struggling to find suitable buyers, the previous-generation Dodge Viper still is still getting plenty of attention. For example, Racing Solutions is now offering an impressive list of upgrades for the fourth-gen Viper.
The tuner offers two different set of upgrades. For between $34,950 and $74,950, depending on options, customers can opt for the RSI Twin Turbo Street Systems that increases the engine’s power to 750 rear-wheel horsepower on the stock engine, 1,000-plus horsepower at the rear wheels on regular gas, and 1,100-plus rear-wheel horsepower on racing fuel. All three levels are downright awesome when considering the base fourth-gen Viper’s 8.4-liter engine hit 600 horsepower and 560 pound-feet of torque.
The RSI Twin Turbo Street Systems includes a pair of 62 mm Presision turbos with blow-off valves, wastegates and piping, a Racing Solutions Fuel System with triple fuel pumps, billet fuel rails, RSI injectors and braided fuel lines, an engine management system update, and custom wiring.
Customers can opt for an RSI blueprinted and balanced shortblock with a custom crankshaft, connecting rods, camshaft. pistons, wrist pins and spiral locks, bearings, and head studs. Additional tuning includes optional RSI cylinder heads, T&D roller rockers, valve springs, ported intake and oversized valves.
Buyers can also update the driveline with a billet-carbon, triple-disc clutch; a spec-built transmission; a custom-spec differential; and racing-spec rear axles.
Along with the engine upgrade, this package also includes RSI badges, painted engine bay and custom floor mats.
