During the recent Ford Racing Invitational, one of the Mustangs being raced by the journalists on hand featured a newly developed intake manifold on its 4.6-liter V8. The current production manifold works very well with all kinds of engine modifications, but once the revs hit 6,500 rpm, it completely falls flat. The new manifold is designed to support a bump of that redline up to 7,500 rpm. The manifold doesn't really add much power on its own, but it does allow other mods like camshafts, valves and exhaust systems to take advantage of more engine speed.

Ford will be building tooling over the next few months and running production prototypes toward the end of summer. The manifold should be on sale later in the fall. Ford hasn't yet set pricing for the new manifold but it may come in at about $600-700. Mike Sutton from Car and Driver who drove a 2009 GT fitted with the new manifold said the engine easily revved beyond 7,000 rpm, something impossible with a stock modular V8.

The price isn't too bad and if it actually does take the cap off the RPMs on the modular motors it would definitely be worth the $.

That intake must be geared towards guys that have forged internals. Ain't no way you should be running the rpm's that high on a stock bottom end.

It is not so important for the internals to be forged when spinning a motor that high, but more important to have a balanced rotating assembly. But if you are going to pull the motor apart to balance the rotating assembly you might as well go with a new forged setup too.

So does that mean that Ford did a crappy job balancing our rotating assemblies? I know Tim does not recommend going over the stock rev limiter (6,200). Also, our cars don't really make power past 6k anyways. But maybe guys with aftermarket heads/cams will continue to make power...

They dont make power past 6k due to the restrictions in the H/C/I setup that are on them from the factory. I can't really speak to the factory balancing job tho... anyone?

Not necessarily, they did a good enough job to allow the car to function within its recommended RPM range. Engineers calculate acceptable tolerances based on the forces shown at a certain RPM. I do not mean to down play the necessity for forged parts because they are necessary to withstand greater forces, which increase with higher RPM's.

so say you have basic bolt ons....would this not be good to put on you stang?

I would have to see a dyno graph to be completely sure about this, but I would assume you would make more power up top. The trade off will be losing some power down low though. You will not fully realize this intakes potential with just bolt-ons though.
