I questioned this a while back during my build. I actually contacted user "Bad Boyz Racing" and here's what he provided.

"I used a 2007 NNBS water pump Part # 12600767, so it would clear my drive by cable throttle body and the upper radiator hose used was for a 2007 NNBS Part # 19130027. "
You can see the water pump neck in this pic of his setup:

 

thats a 78mm intake not a 90mm which runs a bigger TB therefore i dont see how that water pump will help too well. but someone post up some real results using it with a LS2 (90mm) or a 102mm intake

 

NICE! Good find man. Looks like all you would need is a different tentioner and you are good to go

 

when im on nights i tend to get bored an find myself reading a ton of threads on here an ls1tech
