Making a mistake at the start of a race is usually a negative, but for trainer Lee Curtis and his untapped gelding Turbulent Jet it was a turning point.

After the three-year-old finished sixth on debut at Canberra in March when he raced on the speed, Curtis took him to Wyong with a similar game plan.

"The funny thing is when we brought him to Wyong he missed the start and it was a blessing in disguise because he just sat back and went past them," Curtis said.

"He had 40 days between runs so I learned that he needs a good break between runs and to ride him quietly."

Those tactics were adopted for his next start at Canterbury.

Turbulent Jet settled near-last and rattled home to reel in Rastro by a half-length.

The performance was impressive, as was his time of 1.09.71.

"He actually broke Hot Danish's class record that had stood for six years. If he can break her class record, then wow," Curtis said.

"The horse he beat has come out and won again and run second yesterday."

Turbulent Jet will take the next step in his career when he tackles Saturday grade for the first time in the Freshworld Handicap (1200m) at Rosehill.

He will meet the likes of Chris Waller stablemates Oompa Loompa and Relaxed And Happy, along with the Darley-trained pair of Emblems and Knoydart.

The gelding goes into the race as one of the least-experienced runners and at 570kg, probably one of the biggest.

Curtis isn't sure how he will cope with a rain-affected track but long-term, he is excited about his future.

"We've got a wrap on him and he's probably the nicest horse I've had for a while," Curtis said.

"His two wins have been great and we've stepped him up to a bigger league here. I notice they've got him favourite so someone must think he goes alright."

Curtis will also saddle up Calvo in the Sydney Markets Limited Handicap (1400m).

The six-year-old's form has been hot and cold with a Warwick Farm victory in March followed but two unplaced runs.

Curtis said he may have been too kind to the gelding when he gave him a let-up after that win.

"He's tightened up a bit since his last run. I wouldn't be surprised if he runs a cheeky race and he likes it when he gets down in the weights," he said.
