Loosely paraphrasing a Willie Nelson song "Mammas don't let you babies grow up to be NHRA Pro-Stock drag-sled racers," we say why the tarnations not? Who better to spend time with traveling from race to race? Mother and daughter bonding time is essential, some knit together, others cook, as in going really, really fast - down a grassy, or asphalt drag strip - or an icy one for that matter.

Tiina (That Girl) Duncanson is the mother, Kiersten (That Other Girl) is the daughter - together they are That Girl Racing. Both of the Duncanson girls are world record-breaking, grass, drag-sled racers living in Acton, Ontario, Canada. On the track their style is focused aggression, even when facing each other, putting an entirely new face to the expression "man-up." Off the track Kiersten defines their style as "Anything that's tacky. Big glasses, leg-warmers and cardigans, or just a plain tee and jeans."

"We started out last years' NHRA Pro-Stock snowmobile program with a completely new chassis and motor combo. Our first race was at Route 66 in Joliet, Illinois, and the new combo showed some real potential, but ultimately it was just not fast enough yet," explains Tiina.

"We spent many weekends at Toronto Motorsports Park in Ontario, testing the new combo and slowly getting it better. We ran quite a few more races after that, Syracuse, New York, Milan, Michigan, Epping, New Hampshire, and we slowly started to get it fine-tuned and progressively more competitive. Then at US 131 in Martin, Michigan, back in September, it all came together and we ran an outstanding 8.07 @ 157 mph. We qualified number 1, and went on to win the race."

"We are now getting ready for the ‘ice' season. On ice we use different sleds and run 1/8 mile. Our first race is at the World Series of Ice in Port Huron, Michigan, at the end of January. The next race after that is in Quebec, Canada, at St. Joseph de Beauce, on February 19-21. The weekend after that is our last ice race of the season, at Lake Morey in Vermont," continues Tiina.

In early March That Girl Racing moves back to their quarter-mile sleds, running in Valdosta, Georgia, at an AMA motorcycle event were they race sleds as an Exhibition-Class event. Their first actual race is in Atco, New Jersey, on April 10.

"We run the Lucas Oil NHRA Series in Division's 1 and 3. Some of the other tracks we run at are Norwalk, Maplegrove, Indy, Brainerd and Joliet," adds Tiina.

"We always run K&N products on all our motors. We use RU1480's on the ice sleds with the 48mm carbs, and on our asphalt sleds with the 58mm carbs, we use RX4140. We also installed a 63-2576 intake system on our Ford F-450 tow vehicle. We found it increased our fuel mileage over 1 mpg, which is huge on a vehicle that was getting 9 mpg."
