twin turbo duramax
played it at double speed just for shits and giggles, sounds like a big block. suncoast IV transmission with 73,000 miles on it. Converter is shot and needs to be refreshed as soon as I have some spare time to pull it out. Here is the original normal speed video: http://www.youtube.com/watch?v=A7edUZ_Gziw





Duramax S480 custom twin turbos
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)
