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)
Twin Turbo Duramax wins Utica Nationals Truck & Tract Pull!!
My 05 Silver birch Duramax pulling against a few good running Dodges and
Duramax trucks in the open class. I won the class and the pull off with
the white dodge at the end. He pulled 342 feet his first pull (which is
not on vid) I pulled 348 feet to beat him. We had a pull off for
$200....he went 355...I went 367.
