Por mais que o placar mude, torço por esta equipe.

Here por mais que means something like no matter how much, however much, or even if depending on context.

So:

• Por mais que o placar mude... = No matter how much the score changes...

It introduces a contrast: the score may change, but the speaker’s support does not.

This structure is very common in Portuguese:

• Por mais que eu tente, não consigo. = No matter how much I try, I can’t do it.

Because por mais que normally triggers the subjunctive.

• muda = present indicative
• mude = present subjunctive

The subjunctive is used here because the clause expresses something indefinite, hypothetical, or not the main point being asserted. The speaker is not simply stating the score changes as a factual event; they are saying even if / no matter how the score may change.

So:

• Por mais que o placar mude... = correct
• Por mais que o placar muda... = not standard

Placar means score or scoreboard, especially in sports.

In this sentence, o placar mude most naturally means the score changes.

Examples:

• O placar está 2 a 1. = The score is 2–1.
• O placar mudou no segundo tempo. = The score changed in the second half.

So here placar is sports-related vocabulary.

Torcer por means to root for, to cheer for, or to support.

• Torço por esta equipe. = I root for this team.

The verb is torcer. In sports contexts, it is one of the main verbs used for supporting a team.

Examples:

• Eu torço pelo Brasil. = I root for Brazil.
• Ela torce pelo Flamengo. = She supports Flamengo.

Notice that por + o becomes pelo:

• por o time → pelo time

Yes, but the meaning and usage can shift a little.

With teams and people, Brazilians often say both:

• torcer por um time
• torcer para um time

Both can mean to root for a team, and in everyday speech both are common.

But there is an important pattern:

• torcer para que + subjunctive = to hope that...

Example:

• Torço para que eles vençam. = I hope they win / I’m rooting for them to win.

In your sentence, torço por esta equipe is completely natural and clearly means I root for this team.

Both are possible, but esta is a bit more formal or careful.

Traditional grammar often says:

• esta = this, near the speaker
• essa = that, near the listener or already mentioned
• aquela = that over there

In real Brazilian Portuguese, essa is very often used where English would say this or that, especially in casual speech. So many Brazilians might naturally say:

• torço por essa equipe

The version with esta equipe sounds a little more formal, written, or polished.

Both mean team, but they have slightly different flavor.

• time is very common in everyday Brazilian Portuguese, especially in sports
• equipe can sound a little more formal, neutral, or broad

So:

• Torço por este time. = very natural, everyday sports language
• Torço por esta equipe. = also correct, slightly more formal

If this is a sports sentence, time would probably be the more conversational choice.

Because Portuguese often omits subject pronouns when the verb ending already makes the subject clear.

• torço already means I root
• so (eu) torço is optional

Both are correct:

• Torço por esta equipe.
• Eu torço por esta equipe.

Leaving out eu is very normal in Portuguese. You add eu mainly for emphasis, contrast, or clarity.

For example:

• Eu torço por esta equipe, mas meu irmão torce pela outra. = I support this team, but my brother supports the other one.

The comma separates the introductory subordinate clause from the main clause.

• Por mais que o placar mude, = dependent clause
• torço por esta equipe. = main clause

This is standard punctuation in Portuguese, just as in English you would usually write:

• No matter how much the score changes, I root for this team.

So the comma helps mark the pause and the structure of the sentence.

Yes, that is the idea.

The sentence suggests loyalty regardless of what happens to the score. It implies:

• whether the team is winning or losing
• whether the score improves or gets worse
• the speaker still supports the team

So the emotional meaning is something like:

• No matter what the score is, I’m still backing this team.

Sometimes it can feel similar, but although is not always the best match.

In this sentence, por mais que is closer to:

• no matter how much
• however much
• even if

If you say although the score changes, that sounds a little odd in English because although usually introduces a fact, while por mais que here has more of a concessive, open-ended sense.

So the best idea is:

• Por mais que o placar mude, torço por esta equipe. = No matter how much the score changes, I root for this team.

Yes, it is natural and correct, especially in a somewhat polished or written style.

That said, in everyday spoken Brazilian Portuguese, many people might choose slightly more casual wording, such as:

• Não importa o placar, torço por esse time. = No matter the score, I root for this team.

or

• Mesmo que o placar mude, torço por esse time. = Even if the score changes, I root for this team.

Your original sentence is perfectly good Portuguese, but it sounds a bit more elevated than casual sports talk.

Yes. Portuguese allows some flexibility.

Original:

• Por mais que o placar mude, torço por esta equipe.

You could also say:

• Torço por esta equipe, por mais que o placar mude.

That is grammatically possible, but the original order is usually better because it sets up the contrast first.

If you want the sentence to sound smoother and more natural, the original version is stronger.

Yes, but the nuance changes a little.

• placar = the score itself, like 2–1
• resultado = the result or outcome, which can be broader

In sports, placar is more precise if you mean the changing score during the game.

So:

• Por mais que o placar mude... = focuses on the scoreline
• Por mais que o resultado mude... = possible, but a bit less specific or slightly less natural in this exact context

For a live game situation, placar is the better choice.
