Many Beyond Standard Model theories predict an increased number of boosted top quark events making the ttbar system an important stepping stone in the search for new physics. The ATLAS experiment has just finished its second run December 2018 with a total of 140 fb-1 worth of data collected through 2015-2018, with this luminosity, the run 2 data allows an analysis of a greater number of boosted Top quark events with P_T > 500 GeV. This analysis focuses on highly boosted ttbar events decaying via an all hadronic channel being compared with predicted values near high ttbar invariant mass. The prediction values are calculated via Monte Carlo samples for the ttbar decays and a data driven estimate for multijet background. This poster summarizes a simple counting experiment done using a BumpHunter algorithm in a search for a general excess in boosted ttbar events.
