Ford Racing Cobra Jet Intake Thread

[Swiss Boss]

Now what would be nice to see is what power you will make with a custom cam designed for the boss head (13mm lift).

It would be nice to reach 500HP without loosing the low end.

The cams you want exist! They are the CJ cams!

They use the max 13mm lift on intake and exhaust. Duration is smaller than comp cams so you keep your low end...you just won't get as high of a top end, so it probably won't be more than 480rwhp (purely speculating of course).

Checking FordRacingPartsDirect.com this morning and they have the Cobra Jet intake on sale for $699.95. For anyone thinking of making the swap I doubt you will find a lower price than that.

Not exactly true. Tasca Ford has the Cobra Jet intake for ~$653 using the SVTPerformance discount code.

Yes it seems a little low but it looks like they sacrifice some HP to get that torque curve.
Because most of the 500hp+ dyno sheet I have seen, loose a lot of torque below 5000rpm.

Probably has to do with their cam design than the TB I think.

I don't think it has headers, just an offroad H pipe.

Yes but it seems Ford went with a less aggressive ramp than comp cam. I bet you can milk out more power with a very aggressive ramp and keeping the same duration.

I really want to see a comparison between the cobra jet cams and comp cams.

Manuel, which TB are you running?

Is going with the CJ set-up even good for the guys who live with the 5-7K range? Am i even going to notice anything on the street?

Dual...

Steve I would highly suggest cleaning up the CJ intake manifold's runner outlets and smooth the intake up a little bit. I have attached a link to a thread detailing the process and how he did it. I also attached the dyno sheet for everyone to see about the power that he picked up from doing this mod these are SAE results. The only mods he had besides the CJ IM and SCJ TB is cat delete pipes on a coyote 5.0

As far as the throttle body goes, I am more into drag racing then I am road racing and I think the twin bore would be best for you as you stated with the better throttle response. That being said the majority of the gains on the Cobra Jet Intake Manifold are due to the increased size of the throttle body area. I forget who it was at Ford Racing (I am thinking Mike Wilson was the person's name) had even said that the more they tested the Cobra Jet Intake they saw that by increasing the size of the throttle body the more power they were able to make with it. For someone with my ambitions it seems that the SCJ TB is the better route to go with and I will be taking it a step further and going with the Whipple monoblade to see what kind of power it makes. The N/A Cobra jet utilizes the SCJ TB and the 123 MAF while the Aluminator XS uses the 65 dual bore TB.

Thanks for the info Sean. Will put it to good use. I have some time waiting on the FRPP CAI kit for the CJ.

Ford is now saying March 31st before the CJ CAI is available. Has anybody found a work around to this part to support the CJ 65mm twin bore TB? Waiting until March is not a problem, however I am concerned that they are going to push out the delivery once again.

 

[pufferfish]

unless i am mistaken, the twin bore and monoblade have the same size "mouth", where the intake tube would attach? if so, revolution automotive has a killer kit available with a mamouth 5" tube. i believe JLT is also working on something, but who knows when that will be available.

From the looks of it a 2010 cai would work

 

[pufferfish]

it does work, but the maf diameter is undersized for the air volume this intake can move. through the grapevine, JLT is allegedly using their 2010 as the basis for the CJ version. they are just opening the maf size to around 4.5"(114mm).

 

[Justin]

The series three jlt is 4 1/4" http://jlttruecoldair.com/ZenCart/index.php?main_page=product_info&cPath=315_316&products_id=425

 

[ls110]

There are numerous sites selling the CJ 65mm TB. One of these other CAI tubes must fit it such as the JLT the Justin referred to. I should just call a couple of these retailers and ask them what they suggest.

Check out Revolution Auto in Maryland. They are custom making 5 inch CJ intakes. Here is a link to their facebook page where they are showing off their intake on a comp orange boss. They will also paint the tube any color you want.

Guys,

From experience don't reduce the air coming in to the Dual 65 TB...go with the intake from PBH which mates the inlet.

Manuel
