The foundation of the transformation centers on extensive engine work. LMR installed custom CNC-ported cylinder heads featuring titanium intake valves, bronze valve guides, and titanium retainers. The precision work extends to custom five-axis CNC porting, competition valve jobs, and chambers milled for optimal compression. Supporting this head work, LMR fitted its custom-ground LS9 camshaft with LS7 replacement lifters and ARP2000 head studs for reliability at higher power levels.
The supercharger system received equal attention. LMR CNC-ported the 2650 supercharger and snout, then paired it with a high-flow 5-inch cold air intake and 120mm billet throttle body. An ATI 14% lower pulley and Griptec supercharger pulley optimize boost levels, while a Kong billet dual idler belt tensioner maintains proper belt tracking under increased loads.
Fuel delivery required substantial upgrades to support the increased power. LMR installed Injector Dynamics ID1300X flex fuel injectors paired with a complete flex fuel kit, allowing the ZR1 to run on various fuel types, including E85. A Fore Innovations triple pump fuel system rated for 2,000 horsepower ensures adequate fuel flow, controlled by an FC3 staged controller.
The exhaust system features American Racing stainless steel headers with 2-inch to 2-1/8-inch primary tubes feeding into 3-1/2-inch collectors and an X-pipe. This setup not only increases power but also creates the aggressive sound that immediately caught Martin’s attention during the reveal.
Handling the increased power meant upgrading the drivetrain. LMR fitted a Monster S Series triple disc clutch rated for 1,150 rear-wheel horsepower. The combined modifications produce over 1,000 wheel horsepower on E85 fuel, with pump gas figures approaching 900 wheel horsepower. Beyond the engine work, Martin’s ZR1 includes two sets of wheels: carbon fiber Brixton Forge wheels currently mounted, plus 18-inch drag radials on Forgestar Performance wheels for maximum traction at the strip.
All these modifications turn the ZR1 into a serious drag strip car that can still be driven on the street, which is precisely what Hyssong and 717 Supply intended with this build.
