The aim with the Barrawhore was to run a 10-second quarter-mile on a shoestring budget of just $10,000 retail – not Jason’s cost price. Using Jason’s own Tuff Mounts Barra conversion kit – which includes engine and ’box mounts plus gearbox crossmember and sway-bar – along with wrecking yard, eBay, Facebook and Gumtree parts, he’s managed to pull it off pretty much within the original budget.
The engine is a BA XR6 Turbo-spec donk with a set of Plazmaman valve springs, turbo flapper valve mod and 1500cc injectors. Otherwise it’s bone-stock. Backing up the Barra motor is a rebuilt Ford XR6 Turbo-spec BTR four-speed auto with a high-stall converter. From there the factory Holden tailshaft was lengthened 10mm and fitted with a Ford yoke. Out back the Barrawhore ute uses a factory BorgWarner diff with 28-spline axles and 3.45 gears.
It’s a fairly basic set-up, but it’s punching out 470rwhp on 98-octane, which should be enough to see it run into 10-second territory. Already in testing it has gone mid-11s at Calder Park, so come Street Machine Drag Challenge next week we’ll hopefully see the car dip into the 10s.
