After successfully campaigning as a 9-second nitrous car, Mark Sass’ VT Commodore is now aided by boost in the way of a Vortech V-7 side mount blower. The supercharger has certainly woken the Holden up in a big way. This was the first time the car was spun up on the dyno under the boosted combination. The nitrous is still plumbed into the 408ci LS V8 engine but was not used on the dyno. [ SASS Automotive ]
