What Garrett turbo do I have?

Look for the identification name plate of the turbo. In the T series you can usually find it on the body of the turbo or on the inlet plate, held by 2 clinches. Although in the GT series it is usually recorded by computer on the compressor housing or with a name plate held by 2 clinches. via

What size turbo should I run?

The calculation is simple: Divide the absolute outlet pressure that you think you want (14.7 + boost pressure) by the absolute inlet pressure that the Earth says you can have (14.7) and you've got your pressure ratio. Limiting yourself to a reasonable number is the hardest part. via

How much power can a GT45 make?

The GT45 clone seemed to fit the bill, as these were advertised online with power outputs ranging from 600 hp to as high as 800 hp, depending on the seller.

What's the highest PSI for a turbo?

With newer diesels, boost pressures can be as high as 40 psi, yet the engine will remain reliable, and make three to four times the power of a naturally aspirated diesel. A turbocharger in its most basic form consists of only a few parts: a frame, shaft, compressor, turbine, and compressor and exhaust housings. via

What turbo gives the most horsepower?

Twin Honeywell Garrett GTX5544R Gen II 106MM turbochargers boost a 670-cubic-inch hemi engine to 5,300 horsepower, making it the world's highest horsepower recorded on an engine dynamo-meter (dyno). via

What happens if your turbo is too small?

The turbocharger is too small. It cannot move enough air to creat much more power than you are already making. Boost pressure is merely a byproduct of forcing air into the engine. The engine acts like a big restriction in a pipe, the more fluid you force through it, the higher the pressure differential. via

How do you read a Garrett turbo number? (video)

How do you read a turbo number?

Using Precision Turbo's 'chargers as examples, the numbers represent the diameters of the inducer and exducer on the compressor and turbine wheels (measured in millimeters, from tip to tip of the blades on each wheel). With a 62/66, the first two digits are the compressor wheel size (62mm). via

Can I put a bigger turbo in my car?

Adding an aftermarket turbocharger to a car that doesn't have one can be a huge undertaking. However, you can upgrade the actual turbocharger itself, giving you more power due to it's ability to handle more boost. You can also tune up the system with a larger compressor or exhaust housing right for your system. via

What does a r mean on turbo?

A/R stands for Area over Radius. It is defined as the inlet (or, for compressor housings, the discharge) cross-sectional area divided by the radius from the turbo centerline to the centroid of that area. via

How can I make my turbo spool faster? (video)

What size turbo is needed for a 350 small block?

Owner John Urist says that to make 300 to 350 hp at 5 to 7 psi, you need a 54mm compressor. "This supports the power level but still has great response. A larger, 61mm turbo will support 400 to 500 hp," he says. via

How much HP can a turbo 5.3 make?

At what RPM do turbos kick in?

The turbo usually kicks on mine at 3K or just after. via

Is higher turbo PSI better?

The pressure is referred to as boost and expressed in pounds per square inch (PSI). A turbocharger may be able to move enough air than the engine can use even at low pressures thereby causing an instant boost that impacts power. The greater the turbo boost pressure, the greater the engine power. via

What is the normal psi for a turbo?

There's a wide variation, but back in the '90's it was clustered in the 10-12psi range for a typical 4-cyl turbocharged performance model. Nowadays 16-18psi is not abnormal for high performance factory cars. via

Is it possible to have 5000 horsepower in a car?

Devel Sixteen was said to be able to churn out an eye-popping 5000 hp from a quad-turbo V16 engine with a top speed that would exceed 300 mph (480 km/h). Production cars that broke the 1000 hp barrier have only recently come into being, so the Devel Sixteen seemed far ahead of its time. via

How much HP does a Stage 3 turbo add?

Is twin-turbo better than single turbo?

A twin-turbo setup also provides for the reduction of the lag. It helps produce power faster using 4 cylinders, while a single turbo requires all 8 cylinders for an optimal boost. This type of engine is excellent for regular driving in a city or a normal regime. Twin-turbo takes care of smooth engine functioning. via

Why is my turbo fluttering?

That fluttering noise is the sound of a turbo operating in compressor surge, as the compressor 'chops' through the air rather than pushing the air into the engine. Love it or hate it, it's doing nothing good for your turbocharger performance or reliability. This is where a blow-off valve comes into its own. via

What is overspeed on a turbo?

What is Overspeeding? Overspeeding is a term used when a turbo is operating well above its normal operating limits. If there are any leaks, cracks or poor seals between the compressor and the engine, the turbo will have to work much harder than it should to deliver the required air levels to the engine. via

How do I know what type of turbo I have?

The turbo part number can usually be found stamped or etched into the compressor housing of the turbocharger. Other numbers will be visible on the ID plate. These will be Vehicle manufacturer part numbers and build serial numbers. Numbers that you may also see are the turbo frame type ie: TD05, TF035. via
