CTRX 45mm Wastegate – 2-Year Warranty

1. Warranty Summary

Comp Turbo Technology Inc. (“CTI”) warrants the CTRX 45mm Wastegate to be free from defects in materials and workmanship under normal operating conditions for a period of two (2) years from the date of retail purchase.

During this warranty period, CTI will, at its discretion, repair or replace any covered wastegate that is determined to be defective, at no charge to the customer, excluding shipping costs.

2. What This Warranty Covers

This warranty applies to manufacturing related defects only, including:

• Structural defects in the wastegate body, valve, or diaphragm
• Manufacturing or machining defects
• Defects in assembly (e.g., improperly installed internal components)
• Premature failure of the valve guide, diaphragm, or actuator components under normal, recommended use
• Any defect that prevents proper boost control operation and can be traced back to manufacturing or assembly error

Wastegates repaired or replaced under this warranty receive coverage for the remainder of the original warranty period.

3. What This Warranty Does NOT Cover

The warranty does not cover damage or failure resulting from:

• Incorrect installation, improper tightening of cap ring, or installation performed against CTI’s recommended procedures
• Disassembly of the wastegate beyond recommended service steps
• Use of non-CTI springs, diaphragms, or components
• Modifications, porting, machining, polishing, coating, or anodizing performed outside CTI facilities
• Damage caused by debris, foreign objects, or lack of maintenance
• Racing accidents, collisions, fire damage, or any external cause not related to a manufacturing defect

4. Warranty Void Conditions

Warranty becomes void if:

• The product is altered, tampered with, or disassembled improperly
• Serial numbers or identification markings are removed or damaged
• The wastegate is used beyond its intended operating pressure or temperature range
• Failure occurs due to improper routing or omission of cooling lines (if used in high-heat applications)

5. Warranty Claim Procedure

To submit a warranty claim:

1. Contact CT to obtain an RMA Number (Return Material Authorization).
2. Provide proof of purchase (invoice, email receipt, or dealer order confirmation).
3. Send the wastegate to CTI’s inspection facility with the RMA number clearly marked.
4. CTI will inspect and test the product to determine warranty eligibility.
5. Approved warranty items will be repaired or replaced free of charge (customer covers inbound and outbound shipping).

6. Limitation of Liability

CTI’s liability is limited strictly to the repair or replacement of the wastegate. CTI is not responsible for:

• Labor costs
• Vehicle downtime
• Engine or turbocharger damage resulting from improper installation or tuning
• Incidental or consequential damages of any kind

No other expressed or implied warranties exist beyond the terms stated here.

Installation Instructions

Thank you for choosing the Comp Turbo CTRX 45 mm External Wastegate. This wastegate is designed for high-performance turbocharged applications and is suitable for street, strip, and motorsports use when installed correctly.

IMPORTANT NOTES

• Professional installation is strongly recommended.
• Ensure the engine and exhaust system are cool before installation.
• Improper installation may result in boost control issues or engine damage.
• Base spring pressure represents the minimum boost level achievable without electronic boost control.

WHAT’S INCLUDED

• CTRX 45 mm Wastegate assembly
• Pre-installed base spring (as ordered)
• Additional springs (for tuning base pressure)
• V-band connections (if supplied with your kit)
• Multiple 1/8″ NPT boost reference ports

(Included hardware may vary by vendor—verify contents before installation.)

MOUNTING & PLACEMENT

• Install the wastegate on the exhaust manifold or turbo collector, as close to the turbine inlet as possible.
• Ensure the wastegate valve sees smooth, direct exhaust flow. Avoid sharp angles or dead-end placement.
• Position the wastegate so the valve stem is vertical or angled slightly upward when possible.
• Secure the wastegate using the V-band clamp(s) and ensure all connections are tight and centered.

SPRING CONFIGURATION

• The wastegate ships with a base spring installed (example: 7 psi).
• Base boost pressure = spring pressure only (no controller influence).
• To change base pressure:
• Remove the top cap carefully.
• Add or remove springs as needed.
• Reinstall the cap and tighten evenly.

Always ensure the cap and ring are fully seated and tight.

BOOST REFERENCE & PLUMBING

• The bottom port should be connected to a boost pressure source (compressor housing or intake manifold).
• The top port is used for:
• Electronic boost control
• CO₂ or compressed air control
• Unused ports must be properly plugged.

Basic setup (spring-only):

• Boost source → bottom port
• Top port → plugged

COOLANT PORTS (IF EQUIPPED)

• Coolant ports are optional and not required for operation.
• If used, plumb into a low-pressure coolant circuit.
• Do not cap coolant ports unless specified.

FINAL CHECKS

• Verify all V-bands, fittings, and plugs are tight.
• Confirm there are no exhaust or boost leaks.
• Start engine and check for proper operation.
• Monitor boost during initial test drive.
