DRAG Challenge 2019 was Chris Palfreyman’s first stab at the event, bringing his Barra-swapped XD Falcon all the way up from Hobart to be part of the week-long circus.

“A few of my mates have done it before and it’s a really cool event, so I wanted to come over and give it a shot,” said Chris.

Chris built most of the car himself at home on jack stands with a bunch of mates, tackling the engine, wiring, gearbox, chassis mods and also the tuning independently. “There’s no big-name shops,” said Chris, “just a budget rod-and-piston engine built by me, a half-decent ’Glide built by me and a big old stinky turbocharger.”

The basic combo comprises an FG Barra with rods, pistons and custom cams, force-fed by a 94mm Garrett GTX 55 controlled by an MS3Pro Ultimate. “I’m not sure on the power, because we’ve never had it on a dyno, but I’m thinking it should be around 1250hp at the crank,” Chris said.

The rest of the driveline includes a two-speed Powerglide with an SDE 4000rpm converter, sending power to a nine-inch rear end with 40-spline axles and 3.7:1 gears, and rolling on 275 radials – which Chris drove all the DC road miles on as well.

Coming into the week, Chris had a PB of 9.35@158mph to his name. Having never run the XD on the mainland, and given the lack of prepped drag strips in the Apple Isle, Chris had never really had a chance to put some proper R&D into the car when he fronted up to Calder Park for Day One. “If we could run some mid-eights on Friday I’d be super-happy, and just make it through the week,” he said at the time.

By the end of Day One, Chris handed in a PB of 9.14@160mph, before the real drama began on the road to Mildura. “We hit a kangaroo after we stopped to help a competitor, plus we had coolant and fuel leaks to fix and a couple of other dramas,” he said.

On the three days of eighth-mile tracks, Chris laid down 6.32@116mph and 6.21@119mph on Day Two and Three at Mildura respectively, before a 5.9@120mph on Day Four at Portland left just 0.823sec between him and class leader George Lyras heading into the final day back at Calder.

George was struggling to get a decent number out of his Cortina, and when Chris went out and smashed his PB with an 8.71@157mph, it looked as though the race for the top gong in the XR6 Turbo Developments Six-Cylinder class was heating right up. Sadly, that was all Chris could muster. “We’ve been overheating the ’box on the road a bit this week, and that last pass finally killed first gear in it,” he said.

Chris was still all smiles though, finishing second in class and walking away with his ‘I Survived Drag Challenge 2019’ sticker and a killer PB. “Wait ’til we come back next year with more boost, methanol and around 100-150lb less weight,” he enthused. “We’ll get it going fast!”
