One of the quickest late model Holden Special Vehicles’ going around, James Sera’s blown GTS recently ran into the 9-second zone. The street driven HSV is powered by a Magnuson supercharged LSX 427ci V8 engine running on E85 fuel. The car had previously run into the tens with the factory 6-speed manual gearbox and stock internal LS3 engine. Built by Autotechnique [www.autotechnique.com.au ].
