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!
2002 chevy with 8.1 cammed sorry for bad video more coming soon
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.
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!
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.
