Well I had my fast 90/90 combo before my aps kit was ordered and not selling it now. As said APS test mule was running like 20psi with fast 90/90 combo. And if you go to afr site you will find couple of mag build ups that were shooting for like 1000 engine hp that are using the fast 90/90 setup.
One even said they got more power from the fast over the other type or maybe just said they got a better powerband .

They didn't give hard numbers on the diffferences in power though in that article. That new street warrrior might be the intake to get. ls6 is also a decent choice. The fast being two piece is a bit of a pontential and said potential weak point. Some rtv might also be a good idea. I am not planning on past 20psi on my build and hopefully more like mid 15s for boost and maybe a 75 to 100 shot will get me to my 800 to 850 rwhp goal depending on if auto or m6.

 

If your worried about the fast, comp sells a kit that has a new seal to replace the old one.

 

Well 1100whp is what the shop guy said. I'm down with 875rwhp. I'm not that picky.
