Ford's intake manifolds
 

Interesting article comparing all of the ford manifolds for sale.

The boss and cobrajet definitely need bigger cams/ head work.

Not much need for head work when NA CJs are running 9.70s with unported GT heads in Stock Eliminator, and they aren't showing everything they have. Cams yes, in fact I'm pretty much of the opinion now that if the cams can be controlled via VCT still, they aren't big enough.

From what I have read, the results of this test were pretty standard issue. Thanks for sharing the article.

So boss gains hp but loses tq and you need to spin to 7,500 to use it. The CJ intake makes more hp then both and matches the base tq numbers.. I see zero reason for the boss intake any more right?

Werd. Old news really. Seen these tests done independently from guys over on another forum:happy107:.

It would be interesting to see what stock cams, the Cobra Jet manifold and a turbo would do.

The CJ increase has a lot to do with the TB and not solely the intake itself. If you have the BOSS ported you stand a good chance of regaining some of the lost tq and come out cheaper than a CJ and TB. Also; the production CJ intake has been worked and differs from the one you will get off the shelf.

The boss intake was not designed for drag racing. It's for road racing where you spend a lot longer period of time in the upper RPMs and the raised redline can help prevent needless shifts. In road racing peak tq numbers are not the biggest concern so they don't bother with worrying about it. If you want to drag race the road race designed boss IM is not the best option no lol

The CJIM should still be an improvement over the Boss in road racing since it still increases power and torque across the rpm band. So it's still better than the Boss regardless.

I appreciated the side-by-side comparison and technical review of the effects. I wish there was some different manifolds for the 4.0s.

No one has time for V-6's. Hell the aftermarket world is still learning about the coyote.

There's a few out there but most are $$$
