There are a couple LSXR numbers. Looks like it is good for about 12-15hp over a stock LS3, with no portwork possible (hardly impressive)

So... you can make those kinds of gains by porting a stock intake, and even more with ported FAST 92 (again, I don't have any info regarding the 90).

Here is a link to the Formato specials: looks like a FAST + TB is $375. I was wrong about the numbers; he is getting 15-17/18-21 on a stock LS2 manifold. Not bad.
