Horsepower Gain Calculator
Calculate potential horsepower gains from modifications like tuning, exhaust upgrades, intake systems, and more. See how much power you can add to your vehicle.
Step 1: Vehicle Details
Understanding Power Gains
Different modifications yield different horsepower increases. Performance tuning can add 5-15%, while forced induction (turbo/supercharger) can add 30-100% or more. These values are estimates and actual results may vary based on your specific vehicle and setup.
Step 2: Additional Options
About Power Gains
Horsepower gains are typically measured as a percentage of your engine’s base power. Multiple modifications can have cumulative effects, though sometimes with diminishing returns. Always consider supporting modifications (fuel system, cooling) when making significant power increases.

Power Gain Breakdown
Power Gain Formula
New HP = Base HP × (1 + Power Gain Percentage)
To calculate horsepower after modification, multiply the base horsepower by (1 plus the power gain percentage expressed as a decimal). For example: 300 HP with 10% gain = 300 × (1 + 0.10) = 330 HP.
