Key Features

1000+ WHP Capable Stock-Location Turbo Upgrade
Designed for high-power builds while maintaining factory-style installation.
Perfect for street performance, track use, and high-boost applications.

Custom Cast Compressor & Turbine Housings
The IFX1100 turbochargers feature custom cast housings that retain the OEM A/R profile while increasing overall airflow capacity.
Larger A/R sizing improves efficiency at higher boost levels while preserving spool characteristics.

Ceramic Dual Ball Bearing Center Cartridge
The IFX1100 uses a ceramic dual ball bearing center cartridge to reduce friction and improve turbo response.
Compared to journal bearing turbos, this design provides:

• Faster spool time

• Improved boost response

• Greater shaft stability at high RPM

• Increased durability under extreme heat and boost pressure

Ceramic bearings also offer superior heat resistance, making the turbo ideal for high-performance street and race applications.

Enlarged Compressor & Turbine Wheels
The IFX1100 turbochargers use larger, optimized wheels to increase airflow while keeping quick spool characteristics.

• Enlarged compressor wheel for increased boost capacity

• Enlarged turbine wheel for improved exhaust flow

• Optimized blade profile for smooth power delivery

This combination allows the turbo to support over 1000+ WHP with strong mid-range and top-end performance.

MAR-M246 Alloy Turbine Wheel
The turbine wheel is manufactured from MAR-M246 superalloy, a high-temperature material used in extreme motorsport applications.

• Excellent heat resistance

• High strength under extreme boost

• Increased reliability at high RPM

• Designed for long-term durability

Point-Milled Compressor Wheel
Each compressor wheel is precision point-milled to ensure perfect blade geometry.
This improves airflow efficiency, reduces turbulence, and allows stable boost at high pressure levels.

Complete Replacement Units – No Core Required
The IFX1100 turbos are full replacement units.
No core exchange is required, allowing you to keep your factory turbos for resale or backup.

Custom Cold Air Intake System Included
This kit includes a cold air intake system specifically designed for the IFX1100 turbochargers.
Optimized airflow helps reduce turbulence and maximize turbo efficiency for higher power output.

Race-Proven Performance
Tested on stock engine vehicles producing 900+ WHP, with verified results from RaceBox in Houston, TX.
Designed for real-world performance, not just dyno numbers.

1-Year Manufacturer Warranty
Spool Performance backs the IFX1100 turbochargers with a 1-year warranty against manufacturing defects, ensuring confidence and reliability.
