Dear aspirant,
EWS quota is being implemented from this year only so we do not have any previous feedback or idea about how it will affect the merit list this year, it will completely depend on the fact that how many people opted for ews quota this year, out which how many of them are above your rank and how many of the them are applying to mech branch in IIT Kanpur since these stats are not available right now it will be difficult for us to predict anything right now, also for general category cut off rank for mech branch in IIT Kanpur was 1611 so you might / might not have a chance depending upon this years merit fallout.
Hope this helps
