What does T3 and T4 mean on a turbo?

What does T3 and T4 mean on a turbo?

You have probably heard people talking about T3 and T4 turbos in their car. The “T3” number is a general CFM classification. T4 turbos are usually for larger motors and use a different exhaust flange. T4’s can deliver enough air for applications in the 400 to 800HP range.

How much HP does a T3 T4 turbo add?

The high-boost turbo is designed to spool fairly quickly and can support up to 500 horsepower. The high boost turbo is a Garrett TO4E 50-Trim compressor wheel with a stage 3 .

What’s better T3 or T4 turbo?

In general, T3 class turbos can deliver air volume for applications in the 200 to 300 HP range. On the other hand, the T4 turbo has a larger turbine on the exhaust side and larger turbine fins on the intake compressor side. This means that T4 can generate more air at full boost to achieve more horsepower than T3.

Is T3 T4 turbo good?

T3/T4 means bugger all, could be good for anything from about 350 to 700bp depending on spec, just means a big compressor and a T3 turbine flange.

How much power can a T3 turbo make?

around 300-400 horsepower
While power output varies wildly based on the engine the turbo is hooked up to, plus any supporting mods, most vehicles using a T3/4 are operating around 300-400 horsepower.

Do smaller turbos spool faster?

Smaller turbos spool up much faster than a single large turbocharger. Manufacturers may also use strategies such as using a small and a big turbo at the same time. The small unit spools up faster for low to moderate speeds, while the larger turbo kicks in at very high speeds.

How big is a T3 turbo?

How much HP can a T4 turbo make?

It will make 400 whp, but it helps to know what size turbine housing you will be using. There is no way a t3/t4 will boost 28 pounds and make power. It will top out of power in the low 20ish pounds.

How much HP does T3 have?

While power output varies wildly based on the engine the turbo is hooked up to, plus any supporting mods, most vehicles using a T3/4 are operating around 300-400 horsepower.

At what RPM does turbo kick in?

While your car’s engine revs, at cruise, at around 2,000 rpm, a turbo’s turbine can reach rotational speeds of more than 280,000 rpm.

How do you tell if turbo is T3 or T4?

t3 is a rectangle flange. T4 is a square flange. T4 can be a large frame, and uses larger bearings. T3 is small frame and uses smaller bearings.

Is the T3 turbo the same as the T4 turbo?

The T3/T4 turbo is a hybrid. It uses the turbine from a T3 turbo and the compressor housing from a T4 turbo.

What kind of Turbo does a Garrett to4e have?

The high boost turbo is a Garrett TO4E 50-Trim compressor wheel with a stage 3 .63 AR turbine housing and .60 AR on the compressor side. T-3 flange, 4-bolt turbine outlet. If you’re ready to make some big power, this is the turbo for you!

How is the Turbo connected to the exhaust?

The turbo’s connection to the exhaust downpipe is a V-band, so exhaust piping is easy to make. The same goes for air intake and intercooler piping on the compressor side, and like all turbos, you can loosen the bolts on the center section and re-clock the turbo to make it fit nearly anywhere.

Why does a small turbo spool faster than a big turbo?

The smaller exhaust housing (hot side) retains the responsiveness of a small turbo, so it can spool faster. The compressor housing (cold side) of the turbo is a little larger, but not by a lot; this allows it to flow more air without the lag traditionally expected from larger turbos.
