EGR Delete Kits for Detroit Diesel Series 60 Engines: What You Need to Know

EGR delete kits for Detroit Diesel Series 60 engines are aftermarket parts designed to remove the Exhaust Gas Recirculation (EGR) system from the engine. The primary purpose of an EGR system is to reduce nitrogen oxide (NOx) emissions. While deleting the EGR can improve engine performance in some cases, it’s essential to understand the potential benefits, drawbacks, and legal implications before making any modifications.

What is an EGR System?

An EGR system functions by recirculating a portion of the engine’s exhaust gas back into the intake manifold. This process lowers combustion temperatures, which subsequently reduces the formation of NOx. The Exhaust Gas Recirculation system is a standard component on many diesel engines, including the Detroit Diesel Series 60, to meet emissions regulations.

Why Consider an EGR Delete?

Some truck owners consider EGR deletes for several reasons:

• Improved Fuel Economy: EGR systems can sometimes negatively impact fuel economy due to reduced combustion efficiency. Eliminating the EGR system might lead to a slight improvement in fuel mileage.
• Reduced Maintenance: EGR systems are prone to clogging and failure, leading to costly repairs. Deleting the system can eliminate this maintenance concern.
• Enhanced Performance: Some believe that EGR deletes can improve engine performance by allowing the engine to run cooler and more efficiently.

Potential Drawbacks and Legal Considerations

Deleting the EGR system is not without its downsides:

• Environmental Impact: Removing the EGR system increases NOx emissions, contributing to air pollution.
• Legal Issues: EGR deletes are often illegal, as they violate federal and state emissions regulations. Performing such an action could result in fines and penalties.
• Engine Damage: Removing the EGR without proper tuning can lead to engine damage. A professional retune is necessary to ensure the engine operates correctly and safely.
• Warranty Voiding: Modifying the emissions system will almost certainly void the engine’s warranty.

Proper Installation and Tuning

If you decide to proceed with an EGR delete, proper installation and engine tuning are critical. It’s highly recommended to have the work performed by a qualified diesel mechanic with experience in EGR delete installations and custom engine tuning. The engine control unit (ECU) will need to be reprogrammed to account for the absence of the EGR system and avoid error codes or engine damage.

Frequently Asked Questions

Will an EGR delete increase horsepower?

Possibly, though gains can be marginal. The primary goal is typically reliability and reduced maintenance, not significant horsepower increases.

Is an EGR delete legal?

In most jurisdictions, EGR deletes are illegal for on-road vehicles due to violations of emissions regulations.

Can I install an EGR delete kit myself?

While possible for experienced mechanics, it’s strongly recommended to have a professional install and tune the engine after the EGR delete.

Will an EGR delete affect my truck’s resale value?

Potentially. Due to legal and environmental concerns, an EGR delete can negatively impact the resale value, especially in areas with strict emissions standards.

What happens if I don’t tune the engine after an EGR delete?

Running the engine without proper tuning after an EGR delete can lead to engine damage, poor performance, and diagnostic trouble codes.

Summary

EGR delete kits for Detroit Diesel Series 60 engines are a modification that involves removing the EGR system to potentially improve fuel economy, reduce maintenance, and enhance engine performance. However, these modifications can have severe legal and environmental consequences. If you’re considering an EGR delete, carefully weigh the benefits and drawbacks, understand the legal implications in your area, and always ensure proper installation and engine tuning.
