Great manifold, makes power if you have the mods to go with it. Looks INCFREDIBLE
I bought this because I am doing cams and long tube headers, and have a GT500 TB. If you already have CMDPs and you dont have AT LEAST lt headers, you are going to gain next to nothing, and bang for the buck will be next to nonexistant. I know several people here talked about the big difference it made on their close to stock cars, but that is their brain telling them a lie, that they believe, to justify the cost. Dynos dont lie, and delete plate make pretty close to the same power, on basic modded cars, until about 5000rpm, where it makes a LITTLE bit more. Really this isnt worth buying unless you have or plan on cams. UNLESS, you just want the look, which is, INCREDIBLE. It looks unbelievably good under the hood.
Is it worth doing if you arent doing cams? Depends on what you want. If you dont already have charge motion delete plates, this will get you some decent power. Not nearly $600 worth when CMDPs are under 300, but decent nonetheless. Also, if you want an absolutely awesome looking manifold, this is the one to have. It never fails to get attention when I open my hood, there are always a couple people taking cell phone pics of my engine.
Ford tested a combo of this manifold, the FRPP throttle body, Hot rod cams, their CNC heads, and long tube headers and it did 440HP (at the crank, so figure 385ish at the wheels) at 7000rpm. That is the direction I think I am headed. Although I may skip the heads and do a vortech instead.
Makes a very nice high pitched WHOOSH sort of whistle when you hit it, almost reminiscent of a turbo.
Install took me just under an hour, but I have close to 2 decades of wrenching under my belt. I could have done it faster, but I had to keep going back to the fridge for another beer. (I knocked TWO full cans over by accident)
Mine doesnt seem to have the flexing, but even if it DID, Ford has stated that this is "normal" and is no problem, so dont worry about it.
