Sick 5.3 in an 03 Avalanche

[URDONE4]

Dont know if it is really making 700hp with the way it takes off but damn that is a sick twin blower set up on a 5.3 avalanche motor. I wish I could do that to my 07.

Is it me or does that intake tube look a little too flimsy? It looks like that flexible brake cooling hose they use. I can't imagine it would be that robust under boost. But it is different. W2W has a twin rotrex supercharger option for those things too. It would definitely be a fun grocery getter!
