I have already spoken with phunk about his manifold and my application as I chat with him often. He's not of the opinion that his manifold would produce any significant gains at this point. The factory manifold design is actually very good as evident by it still making power above redline with these cams. The issue is getting air into the manifold currently. Is that intake piping? It's likely a part of it. Is it TB diameter? Also likely. There's also a decent chance selective porting of the upper and perhaps lower can yield some gains as well.
I'll be working with Daelen to test once we can decide what the next step is. Personally, I'm gathering a list of options for the TBs and intake piping. It's a game of matching all the parts for a given goal for me.
