T4 Divided vs V-band Test Results- 2026 DSM/Evo Shootout Tech Seminar

ApexTurbo 6466 with a 1.15 A/R T4 divided, and 0.82 A/R v-band turbine housing. Twinscroll vs single-scroll back-to-back dyno on McKenzie's AWD ’90 Eagle Talon. 2.0LR, 10.5:1, cast wet block, GSC S3 camshafts on pump e85, with dedicated v-band and T4 divided turbo manifolds. Each setup purpose built to share the same components- same turbo, same turbo placement, same two wastegates- although not necessary with the non-divided v-band it kept boost control more consistent between setups. 3.5” downpipe/full exhaust, same runner size- even the same primary lengths. All done on the same day with the test car never unstrapped from the Dynojet chassis dyno. Runs done in 3rd gear with similar stabilized fluid and hot parts temps, and each run starting from a steady state/no load 3000rpm.
