custom twin turbos on a duramax diesel. ALL piping/fabrication/welding/design done by myself and my buddy. Borg Warner S480 1.32 A/R primary turbo, stock LLY duramax garrett AVNT-37 variable vane turbo. Piping painted by myself in GM 'dark charcoal metallic' base/clear... stock LBZ short block, LLY heads, C-head gaskets (thicker), big dipper injectors, etc. The first clip was a small tune and rolling start; no boosted launch, and my converter is stupid and doesnt lock until ~50mph if you watch closely. The rest of the video is with a completely stock duramax tune. It makes 33-ish psi with a completely stock tune and 50psi with a small tune (2050us, 20* timing, about a "90hp" tune)
(ok the song playing was on purpose, it was an inside joke for my friends at DuramaxDiesels.com forum)
