JWT Balance Shaft Delete on '07+ Altima?

[ESP]

http://www.sportcompactonly.co...6.htmJust wondering if this is even possible on '07+ models. Has anyone tried this on previous models? If so, what were your thoughts on it?

i google'd it and a host of threads from other sentra/altima forums came up ... end verdict was mixed and reminded me very much of the "issues" reguarding ud pulleys too.... which brings up its own questions of working on the 07+ 2.5 altimas

So what does this do?

reduces rotating mass ... therefore making the internals spin with less effort ... and freeing up a few hp
