GM’s LS3 engine has proven to be a stout performer in every application, and the team at PRW has developed an all-new sheetmetal intake manifold designed to handle boost while improving performance.
“It’s a bolt-on piece that will support boost and nitrous, and we’re very excited about it. It’s in testing on dynos now and will be shipping by the end of the month,” says PRW’s Scott Stutler. “It comes in at a very attractive price point so for you guys that are doing a fabricated race car, that’s a dynamite rig.”
A closer inspection of the manifold shows the wide-mouth O-ring connection at the throttle body, and a set of nice thick flanges at the cylinder head entry to prevent warping.
The company also showcased their wide range of rocker arms at SEMA, from the Sportsman steel roller-tip rocker arms to the Pro Series billet-aluminum rocker arms which use a roller fulcrum and roller tip along with PRW’s proprietary bearing technology.
Their top-line offering, the Pro Series stainless-steel rocker arms, constructed from 15-5 stainless steel and offering the capability of controlling 700 psi of open spring pressure. Like the Pro Series aluminum rocker arms, the Pro Series stainless rockers use both a roller fulcrum and a roller tip – and add a lifetime warranty against body breakage.
PRW’s lineup of rocker arms has been covered extensively here in the past, and the company covers over 100 different engine applications with their rocker arm assortment. They’re willing to offer split-ratio rocker arm sets, and they even offer narrow-body and self-aligning rockers to fit a multitude of applications.
