Caulfield has been a happy hunting ground for Snowden Racing and the father-and-son team is poised to make an impact again at one of the Melbourne track's biggest meetings of the year.

The Sydney-based Peter and Paul Snowden have already won three stakes races at Caulfield this season from 10 starters.

Russian Revolution and Defcon won the Vain Stakes and McNeil Stakes respectively and another three-year-old colt Acatour is one of three early favourites for the stable on Saturday.

Acatour is $2.50 in the Listed Gothic Stakes (1400m) while Tycoon Tara returns to Melbourne racing and is at $2.70 for the Group Two Tristarc Stakes (1400m).

Flippant is the $4.80 equal favourite in the Alinghi Stakes.

Acatour has won three from four in NSW and makes his stakes racing debut after winning a 1500m benchmark race at Rosehill.

"He's a really nice horse," Peter Snowden said.

"He works OK without working brilliantly but he certainly races like he might be a bit above average."

Snowden said there was plenty of merit in his recent win.

"He got a long way back and they did go very fast but he had them rounded up in four strides. Only good horses can do that," he said.

"This will be a test for him the reverse way, but a good draw helps and he's definitely got ability."

Acatour is scheduled to head to the Carbine Club Stakes at Flemington if he performs well, but Snowden is unsure about pressing further into spring.

The team is quite keen to pull up stumps and give him a break (after the Carbine Club). We think there's some good races for him in the autumn," he said.

Tycoon Tara is no stranger to Caulfield having raced there seven times when trained at Warrnambool by Symon Wilde.

She claimed two Group Three wins at the track in February 2015.

Tycoon Tara has won the Missile Stakes, Show County Quality and Golden Pendant since joining the Snowdens, with her only defeat in the Theo Marks Stakes two starts ago.

"She's certainly surprised us and keeps on surprising," Snowden said.

"She's in good order and worked very well on Tuesday morning so she hasn't lost any of her form."
