But tough marking Brisbane coach Anthony Seibold says he won't be satisfied until Tevita Pangai consistently produces the powerhouse display that inspired a rampant 29-10 NRL win over North Queensland.

Pangai set the tone by thumping fellow Tongan heavyweight Jason Taumalolo in an earth shattering tackle before bullying the highly touted Cowboys pack at Suncorp Stadium on Friday night.

He was a one-man wrecking ball, running 115m, with five tackle busts and even helping himself to a 47th-minute try.

Pangai - who is eligible for NSW selection - clearly impressed Blues coach Brad Fittler, who quickly caught up with the runaway prop post-match after completing TV commentator duties.

But Seibold said he wouldn't be happy until Pangai produced the same effort each week.

"The challenge for him is to be consistent and back that up week in, week out," Seibold said.

"I just want to see him reach his potential.

"There are some outstanding forwards in the competition..but certainly Tevita has potential.

"I don't want to overstate where Tevita is at. He's just got to be consistent."

Pangai clearly enjoyed his battle with Tongan teammate Taumalolo, who the Brisbane forward claimed would one day become an Immortal.

Former Dally M Medallist Taumalolo did not have a chance to repeat his staggering 301m effort in last week's win over St George Illawarra after coming off second best with a knee medial strain following Pangai's shuddering eighth minute hit.

And it seems Taumalolo only has himself to blame.

Pangai said his game had improved since chewing Taumalolo's ear in the Tongan camp last year.

"He's a hard man to handle. He's going to be an Immortal one day," Pangai said of Taumalolo.

"He ran 300 metres last week. He's one of the greats of the game.

"And he has taught me a lot. I used to get too fancy. He was always in my ear to just run the ball hard first.

"Now I just want to earn my teammates' respect. I haven't been consistent with that - I have a few rounds to do that now."

Asked about his quick chat with Fittler, Pangai didn't exactly talk up his Blues chances.

"I just said hello (to Fittler) that's it. I am just focused on the Broncos. My job is to play for them," he said.
