Hartley Engines recently dyno’d one of their built Toyota 1GZ-FE V12 engines. The naturally aspirated 5.0 L motor made 720 hp at 10,000 rpm. It features their forged pistons, forged rods, billet camshaft covers, ported heads, individual throttle body system, billet camshafts, and billet dry sump. Hartley Engines also built a twin-turbo version for Jaron Olivecrona’s Lexus RCF drift machine which easily made 1,000+ hp.
