Tech: Inside Pro Line Racing’s HEMI Record-Holding Engines!

As the 2018 racing season is about to kick off in a major way with Lights Out 9, NHRA season opener and more, we are taking a look inside what makes some of the most powerful engines in Pro Line Racing’s stables continue to set records and plant their customers in the winner’s circle.

Pro Line Racing is going on their fifth year of support for the Outlaw Street Car Reunion brand, put together and promoted by Speed Promotions, LLC. The company based out of Ball Ground, Georgia has propelled a number of their customers into the winner’s circle, including at the OSCR event with Daniel Pharris wheeling Andrew Alepa’s Corvette to the RVW title in 2017, claiming the highest purse in OSCR history. Alepa Racing relies upon a HEMI powerplant that PLR has been working on over the past few seasons with numerous R&D teams and dyno sessions.

The HEMI comes in two options, the NHRA-legal 520 cubic inch version or the Outlaw Series packing a hefty 548 cubic inches out of the AJPE / TFX forged aluminum block. A custom billet Bryant Crankshaft rolls the bottom end with BME aluminum rods and custom pistons attached from there. A custom PLR tool-steel camshaft controls the Jesel, Victory 1, Smith Brothers and Reid valvetrain components. System One and Moroso teamed up on the oiling system with their billet wet sump oil pump and a custom kick out oil pan rounds out the bottom end. PLR-exclusive cylinder heads and custom engraved valve covers featuring quick disconnect burn down breather hose ends nearly complete your new engine. Visner Engine Development or a Hogan’s Racing intake manifold completes your engine with a custom throttle body and your choice or PLR’s expert advice on fuel injector selection wraps it up! A number of twin turbocharged entries choose this powerplant while some of the newest editions have been packing a screw/roots supercharger or even a centrifugal supercharger from ProCharger that looks to be a tough combination with Shane Novak’s Camaro and James Lawrence’s Corvette!

Troy Coughlin took the NHRA J&A Service Pro Modified championship in 2017, riding the waves of the legal HEMI while Jose Gonzales took one of the Outlaw ranks all the way to championship glory as well in PDRA Pro Boost. DeWayne Mills and Andrew Alepa showed off radial dominance in 2017 relying upon the PLR HEMI as well.

Shane Molinari, Daniel Pharris, Michael Biehle, Paul Mouhayet (MOITS Racing) and Khalid Mohammad (EKanoo Racing) all relied on PLR HEMI power for making 2017 one of their best ever.
