8.1 liter 496 big block 2500hd
Just a video of my 2500hd with the 8.1 liter allison 5 speed transmission.
pcm4less custom tune k@n cold air intake, magnaflow true dual Exhaust, chipped. Dyno 485 which is pulling power
for this truck. this truck is not set up to race but i have ran a duramax
diesal and ate him for dinner lol. the whining you hear is not the motor
about to blow up its a tensioner pulley going bad.
Friend of ours stuck his HD in the middle of a field, it was like a random
sink hole. Me and my neighbor tried pulling with his 2500hd with warn 16.5
and i pulled him at the same time, it didnt work... so we turned to the
Silverado runs down the street straight piped
I always like the way my old truck sounded straight piped ('99 1500 w/5.3)
so I decided to give it a try with this truck. (2001 2500HD w/8.1) Exhaust is cut off behind the converters then
has a 3" X pipe before going into 2.5" tailpipes with 3.5x18" stainless
echo tips. No muffler. Love that big block rumble!
6.0 2500HD Flowmaster 40 series
warm start with new dual chamber muffler. 4x18 tips rest of truck is stock
except for throttle body spacer.
video doesnt really do any justice. The sound is so much deeper in person
... big step up from before... i have an old vid i will upload later.
