Every install is backed by our in-house dyno tuning, ensuring your setup is safe, reliable, and delivering maximum performance. From street builds to full race applications, we design the system around your goals, fuel type, and engine platform.
Power Adder Options
- Turbochargers – Massive top-end power with efficient boost.
- Superchargers – Instant throttle response and torque on demand.
- Nitrous Systems – Affordable horsepower at the push of a button.
Turbocharger Builds
urbocharging is one of the most efficient ways to create massive horsepower. By using exhaust energy to force compressed air into the engine, a turbo provides explosive top-end power while maintaining drivability.
• Benefits: Huge horsepower gains, efficient boost, and strong performance at high RPM.
• Best For: Street/strip builds, road racing, and high-horsepower daily drivers.
• Our Approach: We select the right turbo size, wastegate, and intercooler setup for your engine platform, fuel type, and performance goals. Then we back it all with precision dyno tuning to optimize air-fuel ratios, boost control, and ignition timing.
Result: Safe, repeatable, and downright addictive horsepower.
Supercharger Builds
If you crave instant throttle response and torque everywhere in the RPM range, a supercharger delivers. Driven directly off the crankshaft, superchargers provide linear boost and unmatched drivability.
• Benefits: Immediate power delivery, predictable boost curve, perfect for towing or street performance.
• Best For: Street cars, muscle cars, towing applications, and anyone who wants torque on tap without lag.
• Our Approach: From centrifugal to roots-style blowers, we install and calibrate the system to maximize your engine’s strengths. With our dyno tuning, you’ll get smooth drivability around town and brutal acceleration when you put your foot down.
Result: Torque and horsepower you can feel the instant you touch the throttle.
Nitrous Oxide Systems
For the biggest bang for the buck, nitrous is unbeatable. A properly installed and tuned system gives you instant horsepower at the push of a button.
• Benefits: Affordable, on-demand horsepower with flexible shot sizes.
• Best For: Drag racing, weekend warriors, and budget builds.
• Our Approach: We install plate or direct-port systems with safety in mind—fuel delivery, ignition retard, and progressive controllers to keep your engine alive while making serious power. Our dyno tuning ensures your setup hits hard without risking reliability.
Result: Clean, controlled power when you want it—and a tame engine when you don’t.
