CJ Intake Manifold Dyno Testing Results

[ford20]

I know that this is with the Roadrunner engine which has an exhaust cam and CNC'd heads but it is the best there currently is, at least it is some indicator of how well this intake performs and confirms what Ford Racing and AM have been saying in comparison to the Boss 302 IM.

Hell with Comp Stage 3 cams I can see this setup some where in the 520-550 range in a Boss 302 considering Power By the Hour has gotten ~470HP out of a stock Boss 302 with Stage 3 cams. It will be interesting to see what this makes when more people like Kdanner and JPC and Evo and eventually MattD get their hands on them (As those are the ones I know who have some high performance N/A 5.0s) and really put this thing through it's paces.

Those dyno curves sure are flaky as hell, especially the Boss intake one. Way too much up and down action going on there.



Less than that. My manifold and throttle body were under $1300 shipped from Tousley. That was the SCJ single blade throttle body, which isn't necessarily needed. A stock GT500 throttle body is significantly larger than the stock 80MM and would work well too

I was thinking the same thing, I haven't really seen a Boss 302 dip like that in those low RPM's, I will see if I can find out more information on that part.

Do you have a pic I can see what it looks like?

Honestly the ones that I have seen, have been using a Steeda CAI with a couple from the tubing to the Throttle Body or they have used their own tubing mounted to the FRPP 123 MAF housing.

waiting to see results with JPC

With my setup I have comp cams stage 3, port and polish heads, bumping the compression up to 13:1, e-85, 1 7/8 American racing long tubes, off road x pipe and outlaw AB. So I wonder with the cobra jet what my car would make NA. I wonder if 600 rwhp NA could be a possibility?

From where you will be I would focus more on dialing in the suspension to get it just right and hook well and reducing some weight in your car

Also FRPP is saying third quarter 2013 as a release for the intake tubing.

Suspension is already done.

If 500 rwhp is achievable, I will start looking at the coyote swap quite seriously.
Would be a hell of a fun car.

It is achievable and has already been exceeded. Honestly I was going to the 5.0 Swap but I decided not to due to the fact it would be roughly the same price as buy a new 5.0 with everything I was going to do to the motor while I had it out of the car. If I were to do it, I would say the best thing to do would be to buy a wrecked 5.0 and than basically drop your body on top of the chassis and swap over the interior.

No, because I'm probably making it tonight, LOL. I do have a selection of parts to do it with though.

But basically, a 5" to 4" reducer coupler on the throttle body, then a 4" aluminum tube with a 90 degree bend pointed toward the driver side, this will then be connected to either a straight or a 45 degree coupler depending on how it all works out, connected to a steeda MAF housing I already had.

Ultimately I need the plastic elbow that was shipped on the 3 or so of the NA CJ cars they actually built along with the 123MM MAF housing Ford Racing sells, as this car is progressing toward becoming a Stock eliminator legal Cobra Jet. Don't know if you've seen the instruction sheet for the manifold, but down at the bottom of it there is a product which will be available later this year, clearly Airaid is the supplier. Unless that is made legal for stock, it won't work for me though.

Dynapacks are like that, no mass, no inertia, I link a post to a stock coyote curve if you want to compare, here.

On the install manual of the CJ intake appears a CAI, maybe is in the plans for FRPP to sell it?

Scroll down to post #46 and you'll see what Adam @ Rev Auto gained with the CJ intake over the Boss intake.

Not really all that impressive for that much money.

Maybe not till the supply of cheap used Boss manifolds dries up. Looked at the price of that lately? It has gone up a lot, it's only $200 less than the CJ now.

True. I got my boss manifold and everything to put it on for 350 dollars brand new.

That is some pretty decent numbers IMO for regrind cams, ported heads and LT's. When you are N/A you gotta pay to play!

I'm hoping when my car is done and the combination I'm doing I hope to be around 550 rwhp.

 

[ford20]

170 HP coming from a N/A engine using the same CI is crazy to me with the modular platform to be honest. I guess that is because with the 3V the best you can do is 130HP with an all out heads and cams build. I would love to see if 600 is possible though but I have heard rumors that the N/A CJ is pretty close to those numbers but I have no idea how truthful that is.

This will do for now.

 

[BLK2012GT]

Thanks for the pic

 

[ford20]

Do you have any idea how you are going to get your hands on the intake tube from a CJ? I would imagine that you would be able to make your own intake tube using the specs from a CJ tube but idk if that would be legal for the class. DO you have to be 100% CJ from the engine to the rear end to run in the class?

A good driver could get close to mid 10's with that NA set up. Is anyone with FI at 522 whp doing that well?
