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.
0-60 run in 8.1L 03 silverado
This is my dad's 2003 chevy silverado 2500HD quad cab. It's got an 8.1
liter, 496 ci vortec with an allison 5 speed tranny. It's not the fastest
truck out there, but it moves pretty good for it's massive size and weight.
Lightning vs 8.1 2500HD (THE REAL FACTS!!)
MY Lightning w/ intake, Exhaust,
pulley, tune and water/methanol injection
Chevy 2500 8.1 w/ Raylar heads, 106cam, Custom intake manifold and a 200hp
shot of Nitrous, a 2800 stall, RUNS RACE
GAS, and launched in 4wd.
Race starts at :19 The Lightning caught the 8.1 at :31 sec and the 8.1
The 8.1 ran a BEST of 12.8 @ 107mph at the track. As VERIFIED by his other
Lightning ran a 12.5 @ 109mph OFF BOTTLE at the track.
Hence why it was a close race. The Lightning ran a best of 11.5 @ 117mph
ON BOTTLE. If the lightning would have had Nitrous that race it would have been over quick!
This is my 1986 gmc SWB 3/4 ton truck with a 2006 8100 vortec and Allison 6
speed tranny. Also has a 14 bolt rear end. I've been playing with my HP
Tuners and have managed 14-15 mpg! Any way this is a tire burning Jose!!
30ft Flamethrower exhaust!
