6.7 Cummins Compound Turbo Kit

A 6.7 Cummins Compound Turbo Kit is a performance enhancement system for the Dodge Ram 1500 diesel truck with a 6.7 liter Cummins engine. The kit consists of two turbos, an intercooler, and related hardware designed to optimize airflow and create more power than a single turbocharger setup would provide. This gives the vehicle improved acceleration, increased fuel economy and better overall engine performance while also reducing backpressure on the motor due to the extra boost provided by the compound turbo setup.

The twin-turbo configuration helps reduce lag time which improves response times when accelerating or climbing hills as well as providing additional torque at lower RPMs resulting in quicker throttle response throughout the entire rev range of operation.

Compound turbo kits are becoming increasingly popular for 6.7 Cummins owners due to the improved performance they provide. A compound turbo kit adds an additional, smaller turbocharger to your existing setup which helps increase horsepower and torque while also reducing exhaust gas temperature (EGT). By combining two different size turbos, you can get the best of both worlds – increased power and better fuel economy.

These kits often come with all of the necessary components such as intercoolers, piping, wastegates, and more so that you can easily install them on your own vehicle. With a compound turbo kit installed on your 6.7 Cummins engine, you’ll be able to enjoy enhanced power output without sacrificing reliability or efficiency in any way!

How Much Horsepower Does a Compound Turbo 6.7 Cummins Have?

The 6.7 Cummins is a powerful engine that has gained a lot of attention in the diesel community. In its stock form, it produces up to 850 horsepower and 1,050 ft-lbs of torque. However, when you add two compound turbos to this already robust engine setup, it can reach an astronomical amount of power!

With the right combination of upgrades such as tuning and fueling components, some have achieved over 1,500 horsepower from their 6.7 Cummins with compound turbo setups! It’s important to keep in mind though that achieving these kinds of numbers requires great attention to detail and experience with working on these engines. Achieving this kind of performance safely also requires proper maintenance and monitoring so make sure you’re well-equipped for any work before attempting such modifications yourself!

Is Compound Turbo Better Than Single?

Compound turbos are becoming increasingly popular in the automotive industry, as they offer a number of advantages over single turbochargers. A compound turbo setup consists of two or more turbos working together to produce greater power output than a single unit. The first turbo (high pressure) helps reduce exhaust backpressure and decreases lag time by spooling faster, while the second (low pressure) increases boost levels and keeps them consistent throughout the power band.

This combination can provide up to 50% more horsepower than a standard single-turbo setup and often results in improved fuel efficiency due to lower exhaust temperatures. Compound turbos also have the advantage of being able to run at different speeds depending on engine load; this allows for better overall control over power delivery during various driving conditions. Additionally, these systems are usually more reliable since there is less strain put on individual parts due to their multiple units working together rather than just one large unit dealing with all the stress.

All these benefits make it easy to see why compound turbos are becoming an attractive option for many car enthusiasts who want extra performance without sacrificing reliability or economy.

How Much Hp Does a Compound Turbo Add?

Compound turbos are becoming increasingly popular as a way to increase horsepower, torque, and overall performance in modern engines. Compound turbos, which pair two turbochargers together, can add anywhere from 30-75 additional horsepower to an engine depending on the size of the turbo setup. This is because compound turbos allow for more air flow into the cylinders compared to single turbo setups due to their ability to generate higher boost pressures.

Additionally, compound turbos are able to better control exhaust gas temperatures (EGT) than single turbo setups for smoother power delivery and engine longevity. Overall, compound turbos offer significant gains in horsepower when properly sized and tuned correctly by an experienced mechanic or tuner.

How Much Boost Can a Stock 6.7 Cummins Handle?

The 6.7 Cummins is a powerful engine and capable of handling an impressive amount of boost pressure. Depending on the condition and modifications, these engines can handle anywhere from 25-45 PSI of boost pressure with proper tuning. With higher levels of boost, you may need to consider upgrading the fuel system or other components in order to ensure it remains reliable under high stress conditions.

For stock 6.7 Cummins engines that have not been modified, it’s recommended to keep the boost level between 20-25 PSI for optimal performance without putting too much strain on the engine components and risking potential damage or failure due to overloading them with excessive amounts of power.

Best Compound Turbo Setup for 6.7 Cummins

Compound turbocharging is a great way to increase the power and efficiency of your 6.7 Cummins engine. The best compound turbo setup for the 6.7 Cummins will depend on the type of driving you do and how much power you want to get out of it, but typically, an S400 frame-mounted turbo with a smaller stock-location Holset HX35 or HX40 will provide good response while supporting up to 550hp. Additionally, adding an air-to-air intercooler can help reduce EGTs and further improve performance.

6.7 Cummins Add a Turbo Kit

Turbocharging a 6.7 Cummins diesel engine is a great way to increase power and efficiency without having to replace the entire engine. A turbo kit includes all of the components necessary for installation, including an upgraded turbocharger, high-flow exhaust manifold, new air intake system and custom tuning. With the right setup, you can expect up to 35% more power from your vehicle with improved fuel economy too!

5Th Gen Cummins Compound Turbo Kit

The 5th Gen Cummins Compound Turbo Kit is a great way to unlock the power potential of your Cummins engine. This kit includes two top-of-the-line turbos, an S300 and an S400, that work together in unison to provide maximum performance. The larger turbo provides more boost at lower RPMs for improved throttle response and torque, while the smaller turbo kicks in later for added top end power.

With this setup you can expect increased horsepower, torque and fuel efficiency from your Cummins engine.


The 6.7 Cummins Compound Turbo Kit is an excellent upgrade for those looking to take their diesel engine performance to the next level. It is a powerful and reliable product that offers improved power, increased torque, better fuel economy, and quicker acceleration. With its simple installation procedure and competitive price point, this kit provides an excellent value that any diesel enthusiast should consider adding to their vehicle.

Whether you’re looking for more horsepower or just greater overall efficiency from your truck, the 6.7 Cummins Compound Turbo Kit makes a great choice!
