Why Twin Turbo For 454 Big Block is Necessary

I have a 454 big block Chevy engine in my 1970 Chevelle SS. It’s a great engine, but it’s also a thirsty one. I’ve been looking for ways to improve the fuel economy without sacrificing power, and I think I’ve found the answer: twin turbos.

Twin turbos can help improve fuel economy by forcing more air into the engine, which allows it to burn more fuel efficiently. This can result in a significant increase in fuel economy, especially at highway speeds.

In addition to improving fuel economy, twin turbos can also increase power. This is because the forced induction of air into the engine allows it to produce more power at lower RPMs. This can make the car more responsive and fun to drive.

Of course, there are some downsides to twin turbos. They can be expensive to install and maintain, and they can also make the car louder. However, for me, the benefits of twin turbos outweigh the drawbacks.

If you’re looking for a way to improve the fuel economy and power of your 454 big block engine, I highly recommend considering twin turbos. They’re a great way to get the best of both worlds.

Here are some specific reasons why twin turbos are necessary for a 454 big block engine:

• Increased power: Twin turbos can increase the power of a 454 big block engine by up to 50%. This is because the forced induction of air into the engine allows it to produce more power at lower RPMs.
• Improved fuel economy: Twin turbos can improve the fuel economy of a 454 big block engine by up to 20%. This is because the forced induction of air into the engine allows it to burn more fuel efficiently.
• Better throttle response: Twin turbos can improve the throttle response of a 454 big block engine. This is because the forced induction of air into the engine allows it to produce more power at lower RPMs.
• Less lag: Twin turbos have less lag than single turbos. This means that there is less of a delay between when you press the gas pedal and when the engine produces power.

Overall, twin turbos are a great way to improve the power, fuel economy, and throttle response of a 454 big block engine. If you’re looking for a way to get the best of both worlds, I highly recommend considering twin turbos.

My Buying Guides on ‘Twin Turbo For 454 Big Block’

Introduction

If you’re looking to add some serious power to your 454 big block, a twin turbo setup is the way to go. Twin turbos can boost horsepower and torque by up to 50%, and they can also improve your engine’s throttle response.

But before you start shopping for a twin turbo kit, there are a few things you need to know. In this buying guide, I’ll walk you through the process of choosing the right twin turbo kit for your 454 big block.

What to Consider When Choosing a Twin Turbo Kit

There are a few factors you need to consider when choosing a twin turbo kit for your 454 big block. These include:

• Engine size: The size of your engine will determine the size of the turbochargers you need. Generally speaking, you’ll need a larger turbocharger for a larger engine.
• Horsepower goals: How much power do you want to make? This will also affect the size of the turbochargers you need.
• Budget: Twin turbo kits can range in price from a few thousand dollars to tens of thousands of dollars. It’s important to set a budget before you start shopping so you don’t get sticker shock.
• Installation: Do you plan to install the kit yourself or have a professional do it? If you’re not comfortable working on cars, it’s best to have a professional install the kit.

Types of Twin Turbo Kits

There are two main types of twin turbo kits: sequential and parallel.

• Sequential turbo kits are the most common type. They use two turbochargers that are arranged in series. The first turbocharger compresses the air, and the second turbocharger compresses it again. This type of kit is more efficient than a parallel turbo kit, but it’s also more expensive.
• Parallel turbo kits use two turbochargers that are arranged in parallel. The two turbochargers compress the air at the same time. This type of kit is less efficient than a sequential turbo kit, but it’s also less expensive.

Choosing the Right Turbochargers

The size of the turbochargers you need will depend on the size of your engine and your horsepower goals. A general rule of thumb is to use a turbocharger that’s about 1.5 times the size of your engine’s displacement. For example, if you have a 454 big block, you would need a turbocharger that’s about 680 cubic inches.

You also need to consider the boost pressure you want to run. Boost pressure is measured in pounds per square inch (psi). The higher the boost pressure, the more power you’ll make, but the more stress you’ll put on your engine.

Choosing the Right Intercooler

An intercooler is a heat exchanger that cools the air after it’s been compressed by the turbochargers. This helps to improve efficiency and prevent engine damage.

The size of the intercooler you need will depend on the size of your turbochargers and the amount of boost pressure you’re running. A general rule of thumb is to use an intercooler that’s about twice the size of your turbochargers.

Choosing the Right Fuel System

A twin turbo setup can put a lot of strain on your engine’s fuel system. You’ll need to make sure that your fuel pump, injectors, and fuel rails are up to the task.

If you’re going to be making a lot of power, you may also need to upgrade your fuel tank.

Choosing the Right ECU

Your engine’s computer (ECU) needs to be able to control the twin turbo setup. You’ll need to make sure that your ECU is compatible with the turbochargers, intercooler, and fuel system you’ve chosen.

Installation

Installing a twin turbo kit is a complex job that requires specialized tools and skills. If you’re not comfortable working on cars, it’s best to have a professional install the kit for you.

Conclusion

A twin turbo setup is a great way to add power and performance to your 454 big block. But before you buy a kit, be sure to do your research and choose the right components for your needs.
