Chasing the H-Pattern Record with a Precision 6870
Powered by a Precision Gen 2 6870 Turbocharger, this DSM is built to prove just how far a factory-style combination can go. Backed by a stock ECU running ECMLink and a stock 5-speed transmission, the setup has already delivered an impressive 9.45-second pass at 163.9 mph.
Supporting the Precision turbocharger are Manley TurboTuff rods, Wiseco 1400HD pistons, Kiggly valve springs, GSC S2 cams, a Morrison Fabrication manifold, an ETS 4-inch front-mount intercooler, a JMFab Race intake manifold, an Aeromotive 5.0 GPM variable-speed fuel pump, and FIC 2250cc injectors.
Owner and tuner Dave Oskim of Oskim Performance has his sights set on breaking the H-Pattern ECMLink record of 8.77 seconds before making the switch to a Haltech engine management system.
