It's likely to be 'race through' if it's talking about present time or 'raced through' if it's using a past tense. If you race through something it means that you do it quickly. It's a kind of weak joke, based on the fact that it would take a long time to drink 165 million cups of tea in a day. In fact, if you work it out, that's only an average of a couple of cups of tea per day per person, so there's no need to race through them - you could drink them as slowly as you like. 'Raise through' doesn't mean anything. It's also more likely to be 'whopping' rather than 'whooping'. Whooping means to make a sudden noise; 'whopping' is informal English meaning 'large'.

Hello! People from the UK *LOVE* drinking tea. I know some people who will drink up to eight cups of tea per day! I think it is very likely that the host said "raced through". This is an idiom which means 'to perform something very rapidly'. In this case, it's tea drinking!

Hi, Alice, allow me to address the source of your confusion. Native speakers speak “automatically”, so are generally not consciously aware of how they pronounce their own language. As a phonologist, I would like to point out to you that the difference between the pronunciation of “raised” and “raced” is not just the final consonant cluster (/zd/ versus /st/), but really the length of the preceding vowel. This is true in all varieties of native English, and in some varieties this difference in vowel length is far more important than the quality of the final consonants. As a non-native speaker, your lack of bias should allow you to hear the difference more easily than a native. If you’re interested in mastering this skill, listen to the recordings below, and you tell me which word has a longer vowel sound:

It would be safer to say "raced" because I really cannot see the use of raised in tea cups. Maybe if they talked about the money involved, it would make more sense, but this is more of a "passed out" and raced through could get to "handed costumers in a timely fashion" or fast.
