A supercharger compresses air using a belt-driven compressor, allowing the engine to consume more fuel and air mixture. This results in significantly higher power output compared to naturally aspirated engines.
Enter your engine's naturally aspirated horsepower, the boost pressure in PSI, select your boost type, and set the system efficiency. The calculator will show your boosted horsepower and power gain instantly.
Superchargers are belt-driven and provide instant power but consume engine power. Turbochargers use exhaust gases, are more efficient, but have turbo lag. Both compress air to increase engine power output.
A turbocharger typically adds 30-40% more power, but this depends on boost pressure, engine size, and tuning. Higher boost pressures can add 50-100% or more power with proper supporting modifications.
Turbo size depends on your horsepower goals, engine displacement, and desired power band. Smaller turbos spool faster but limit top-end power, while larger turbos provide more power but with increased lag.
System efficiency accounts for losses in the intake system, intercooling, and combustion efficiency. Typical values range from 60-90%, with well-tuned systems achieving higher efficiency ratings.
Yes, but it requires significant modifications including fuel system upgrades, engine management tuning, and potentially internal engine strengthening. Professional installation and tuning are highly recommended.
