On 11 May the colt was moved up in class and distance for the Group Two Prix Hocquart over 2400m at the same course and finished fourth behind Mot d'Or, Providential and Belgio, beaten just over two lengths by the winner.
Ridden as usual by Saint-Martin he moved into second place in the straight but was unable to make further progress and was beaten one and a half lengths by the 54/1 outsider Policeman.
Shakapour was then matched against older horses in the Grand Prix de Saint-Cloud over 2500m on 6 July and started the 3/1 second favourite behind the four-year-old colt Scorpio, the winner of the Hardwicke Stakes.
Shakapour, racing alongside the 1979 Pix de Diane winner Dunette, moved past Policeman to dispute the lead inside the final 200m.
The judge declared a dead heat with the supporters of both horses having grounds to consider themselves unlucky: Saint-Martin had dropped his whip 200m from the finish, while George Doleuze on Dunette appeared guilty of premature celebration, raising his arm in triumph a stride before the line.
The best of his offspring was the filly Khariyda who won the E. P. Taylor Stakes, Premio Lydia Tesio and Prix Fille de l'Air for the Aga Khan in 1987.
