Like all Turbosmart blow off valves, the new Kompact Shorties have been machined in-house, from solid billet aluminium. Keeping the process in-house, ensures only the best quality, and none of the cracking or leaking that plague the factory plastic valves. Like their predecessors, they ve been engineered with a light-weight, brass/aluminium, two-piece piston. Carefully engineered springs make these the most responsive valves of their kind. The Kompact Shortie fits a huge range of turbos, and their tiny dimensions make them a breeze to fit. To make things even easier, Shorties are supplied with both a swivel banjo nipple and a straight nipple, meaning you can tailor the valve to better suit your application. Larger o-rings have been fitted in the base to aid ease of installation another modification made after talking to our authorized dealers and installers. Small design means Shortie is easy to install. All billet construction, and well-designed internals mean it will hold as much boost as you want to throw at it, for as long as you need it to. The Plumb Back version is as quiet as a factory valve, or if you re looking to make a little noise, the Dual Port version s superior flow characteristics will safely provide that BOV sound you re looking for. The new twin fixed ports flow more than ever before. You just can t lose with Turbosmart s Shortie.
