National forward Faisal Saari grabbed a hattrick with goals in the 19th, 31st and 57th minutes.
BPSS-Thunderbolt’s other goals came from Firhan Ashaari (15th, 68th), Fitri Saari (16th), Faiz Helmi Jali (24th), Shaiful Nizam Aswan (46th) and Fahmi Zainal Abidin (52nd).
Ipoh City Council, who finished third in Division Two, got a consolation goal through Azrul Fazri in the 50th minute.
BPSS-Thunderbolt coach Wan Roslan Wan Abdul Rahman said he never expected his boys to chalk up such a big win.
“I was expecting a strong challenge from the Ipoh team but it turned out to be a very one-sided match,” said Wan Roslan.
“It was a good morale-boosting win for us ahead of the semi-finals.”
Division One champions BPSS-Thunderbolt, however, will have to wait until tomorrow to know who their opponents will be in the semi-finals.
This is because the quarter-final clash between Petaling Jaya City Council (MBPJ) and BPSS Juniors will be played tomorrow as six of the Johor sports school’s players will only be returning from Germany today after featuring in the four-nation Under-16 tournament.
Defending champions Bukit Jalil Sports School (BJSS) also reached the semi-finals with a 4-0 thumping of Division Two champions MSN Sabah at the same venue.
S. Kavin Kartik also bagged a hat-trick, with his three penalty corner goals coming in the 16th, 32nd and 51st minutes. Dangerous Lee chipped in with a goal in the 43rd minute.
BJSS will face debutants Universiti Kuala Lumpur (UniKL) in Friday’s semi-finals.
UniKL staved off a strong challenge from Division Two runners-up MSS Pahang to win 4-2 at the KL Hockey Stadium.
Nor Hizat Sumantri, who just returned home after playing in the Dutch Division Two, scored a brace in the 58th and 65th minute. The other UniKL goals were scored by Sabri Mohamed (2nd) and Manraj Singh (19th).
Fahmi Abdullah (10th) and Zulhannan Mazlan (67th) replied for Pahang.
