BRENDAN IRVINE HQ HOLDEN
BRENDAN Irvine’s bright red Quey has been through a couple of iterations, but its current one is by far the best. “I bought it in 2010 – it was a nice, presentable car with a 308, TH400 and 9in, and I used it for drag racing and skid comps,” he said.
While the driveline was pretty healthy, the interior and body were in need of some tidying up, so the HQ was blown apart and Brendan slathered it in straight red tinter in his shed, just in time to be his wedding car!
A few years later, with a view to making the car more streetable, Brendan yanked the grumpy 308 and swapped in a Vz-spec LS1 with a Harrop blower, good for 700hp. The grunt heads rearwards through a suitably worked DTM 4L60E trans.
“I wanted it to be a car that I could throw the family in and go for a long drive, but would also stop and steer well,” Brendan said.
To handle the substantial increase in power, the rest of the HQ’S underpinnings were beefed up as well. Brendan braced the body and added Rod Shop upper and lower control arms to the front end, while under the bum, the diff is a shortened XY 9in with 3.5:1 gears. The motion of the ocean is controlled by QA1 shocks at all four corners, with BA Falcon discs and calipers hauling the car up from the crazy speeds Brendan is happy to take it to.
Getting the rear tyres to stay in contact with the tarmac proved to be a serious issue for Brendan at OSUSC, with the Quey slipping and sliding its way to 220km/h down the main straight, so there’s a tyre change and some suspension tuning on the cards before the next event.
Even with the traction issues, Brendan pedalled the HQ to a convincing win in the hotly contested Vintage class. “This event was great because you had to perform in all aspects of performance, not just one,” he said.
