How much horsepower does a 1991 Stealth RT have?
The 1991 Dodge Stealth R/T delivers about 250 horsepower in U.S. specification, with small variations by year and drivetrain.
Engine and model context
The Stealth line shared its architecture with Mitsubishi's 3000GT, and the R/T trim represented the early performance-focused variant. While the top-tier Mitsubishi 3000GT VR-4 Twin Turbo produced about 320 horsepower, the Stealth R/T was tuned for a high-performance but lower-output package appropriate to its market positioning. Exact horsepower can vary slightly by model year, emission controls, and whether the car uses a manual or automatic transmission.
Note: horsepower figures for the Mitsubishi 3000GT VR-4 Twin Turbo are higher (around 320 hp) but apply to a different model than the Stealth R/T.
Power figures by source
Before listing the common published ranges, it's useful to acknowledge that early-1990s ratings could differ depending on whether SAE net or older gross ratings were used, and whether the vehicle had catalytic converters installed at the factory.
- U.S.-spec Dodge Stealth R/T (1991–1992): typically around 245–250 horsepower (SAE net), with torque commonly cited in the mid-260s to mid-270s lb-ft range, depending on transmission and exhaust configuration.
- Some contemporary materials and road tests show figures closer to 240–245 horsepower for certain years or configurations due to differing measurement standards and emissions equipment.
- Related model context: the Mitsubishi 3000GT VR-4 Twin Turbo, not the Stealth, delivered about 320 horsepower, illustrating how the Stealth R/T sits between the base NA models and the higher-performance VR-4 variant.
In practice, most credible references place the 1991 Stealth R/T near 250 hp in the U.S. market, with minor year-to-year and drivetrain variations.
Related model context
For comparison, the Mitsubishi 3000GT VR-4 Twin Turbo offered substantially more power (about 320 hp) in the same era. The base Stealth and other trim levels carried lower outputs, aligning with their market positioning and equipment.
What to verify when researching horsepower today
If you’re checking a specific car’s power output today, verify the exact model year, market, and drivetrain, as well as whether the vehicle retains factory equipment and emissions controls. A professional dyno test can provide a current figure, though results may vary with wear, maintenance history, and aftermarket modifications.
Summary
The 1991 Dodge Stealth R/T is commonly cited at about 250 horsepower in U.S. specifications, with typical ranges from roughly 240–250 hp depending on year and measurement standards. This places it below the top-tier VR-4 variant (around 320 hp) and above the base models, reflecting its role as a capable early performance trim in the Stealth lineup.
