I see that you have got 8000 rank in ews category in homestate quota , and you want to join nit surathkal. See , as ews quota is included for the first time this year, so we can't find any record so that we can say which branch you will get. You can although see the mock seat allotment , it will say better which branch you are more likely to get.

But what i think is that 8000 rank is too much according to me. 

Hope it helps.

thank you.
