“We'll see how we go tomorrow,” said the man who took the #17 Mustang to wins in both races at last year's Adelaide event.
“I think we probably don't have, at the moment… We probably need to keep searching for a 19.2.
“I think we're not too far away but really, for me, (it was a) promising day because we didn't really roll out that well and we've sort of just tuned it up over the weekend and it's really nice now.
“So, I'm really excited for tomorrow.”
McLaughlin also had praise for the 27-year-old who made the off-season switch to another joint venture team.
“Just showing what those blokes had last year,” commented the back-to-back champion.
“I think at the end of the day Chaz has come in and first time is pretty impressive.
“I think he's doing a great job; it was a great lap.”
Both Mostert and McLaughlin earned direct passage to the second part of both of the qualifying sessions which set the grids for this weekend's 78-lappers around the Adelaide Parklands Circuit.
The first of those qualifying sessions takes place tomorrow from 11:55 local time/12:25 AEDT.
