Eu vou torcer por esta equipe.

This is a very common Portuguese way to talk about the near future.

• vou = I go / I am going
• torcer = to cheer / to root

So eu vou torcer literally looks like I am going to cheer, and in natural English it often means I’m going to root/cheer.

This structure is:

ir + infinitive

Examples:

• vou estudar = I’m going to study
• vamos sair = we’re going to go out
• ela vai chegar = she’s going to arrive

So eu vou torcer is just the normal future expression here.

In this sentence, torcer means to cheer for, to root for, or to support a team.

Be careful: torcer can also mean to twist in other contexts.

For example:

• Torci o pé. = I twisted my ankle.
• Vou torcer pelo Brasil. = I’m going to cheer for Brazil.

So the meaning depends on context. With sports, teams, and competitions, torcer usually means to root for.

Because torcer often takes por when it means to root for / cheer for someone or something.

So:

• torcer por alguém
• torcer por uma equipe
• torcer por você

Examples:

• Torço por você. = I’m rooting for you.
• Eles torcem por esse time. = They root for that team.

Think of torcer por as a set expression.

Yes. In Brazilian Portuguese, both torcer por and torcer para are used.

Examples:

• Eu torço por esta equipe.
• Eu torço para esta equipe.

Both can mean I root for this team.

That said, many speakers strongly associate torcer para with sports teams:

• Eu torço para o Flamengo.

And torcer por is also very common, especially with people or outcomes:

• Estou torcendo por você. = I’m rooting for you.

In real Brazilian Portuguese, you will hear both. If you use torcer por here, it sounds natural.

Yes, you can leave out eu.

Portuguese often drops subject pronouns when the verb already makes the subject clear.

So both are natural:

• Eu vou torcer por esta equipe.
• Vou torcer por esta equipe.

Because vou clearly means I am going, the eu is optional.

Speakers may include eu:

• for emphasis
• for contrast
• for clarity

Example:

• Eu vou torcer por esta equipe, mas ele vai torcer pela outra.

Because equipe is a feminine noun in Portuguese.

So the demonstrative has to agree with it:

• esta equipe = this team
• essa equipe = that/this team
• a equipe = the team

You would use masculine forms with masculine nouns:

• este time
• esse time

So:

• equipe → feminine → esta / essa
• time → masculine → este / esse

Traditionally, Portuguese makes this distinction:

• esta = this, near the speaker
• essa = that, near the listener or previously mentioned

However, in everyday Brazilian Portuguese, this distinction is often relaxed, and essa is very common where English would say this.

So in real speech:

• esta equipe sounds correct and a bit more formal or careful
• essa equipe is also very common in Brazil

A learner should understand both. If you say esta equipe, it is absolutely correct.

Yes, very often you could say time instead.

Both can refer to a team, but they are not always identical in tone:

• equipe = team, group; a bit broader and sometimes more formal
• time = team, especially in sports; very common in Brazil

So in a sports context, many Brazilians would naturally say:

• Eu vou torcer por este time.

Your original sentence with equipe is still correct and natural, especially in a more neutral or slightly formal style.

Yes, vou torcer is natural.

But depending on context, Brazilians might also say:

• Torço por esta equipe. = I root for this team.
  (general habit or preference)

• Estou torcendo por esta equipe. = I’m rooting for this team.
  (right now / in progress)

• Vou torcer por esta equipe. = I’m going to root for this team.
  (future intention)

So the choice depends on the situation:

• general support → torço
• current action → estou torcendo
• future intention → vou torcer

Good question. Portuguese often contracts por + article:

• por + o = pelo
• por + a = pela
• por + os = pelos
• por + as = pelas

Example:

• Torço pelo time. = I root for the team.

But in your sentence, the next word is esta, a demonstrative, not a definite article by itself in this structure, so you keep:

• por esta equipe

So:

• pelo time
• pela equipe
• por esta equipe

All of these are correct, depending on what comes next.

A simple learner-friendly pronunciation is:

• torcer ≈ tohr-SER

A few helpful notes:

• the stress is on the last syllable: cer
• the r at the end of the infinitive is often softer in Brazilian pronunciation
• in many Brazilian accents, the final r may sound like a light h sound

So torcer may sound roughly like:

• tohr-SEH or
• tohr-SER, depending on accent and how carefully someone is speaking

And the whole sentence is roughly:

eu vou torcer por esta equipe
≈ eh-ooh voh tohr-SER pohr ES-tah eh-KEE-pee

That is only an approximation, but it can help you get started.
