CJ Intake Manifold Dyno Testing Results

[ford20]

I found this little bit of information. Apparently this was done on a Boss 302S. The Mods are listed below and the only thing added between the baseline run and the final run was the IM, TB, and the 123 MAF housing.

I will post the dyno graph later today as it is on my work computer or Mark if you have the copy I sent you , you can post it.
The increases are 30 rwhp and 20 rwtq with gains right across all rpm levels and it makes power up to 7800 rpm.
We will run it to 8000 once we install the high rpm pulse ring. All the dyno runs were done at the dealership on our Dynopack dyno and the tuning done by us with a SCT tuner.
The mods are AR 1 7/8 longtube headers , full 3 inch race exhaust with x pipe and a SCT tune . We used a temporary cold air intake for the dyno runs , we are making a permanent one this week .
Driveability seems fine but remember its a 302S so my street driving is limited to around the block trips.
The parts used are the CJ intake , CJ throttle body and the 123 mm maf housing

Wow

I am just happy to see ANY data. For a while I thought the Cobra Jet manifold was a myth.

I just want 7800 rpms...

 

[fdjizm]

helluva gain for an intake!

 

[firestang70]

I wonder what the gains would be on a Coyote motor vs. Roadrunner. The power curve looks great there.

 

[Rasmus]

Nice gains. Thread title should be changed though.

 

[Retro5.0]

Nice gains for sure!! But I would really like to see what the gains would be like on a Coyote with the 6R80.

 

[R1V3R5]

At least the manifold is finally available. I'm waiting for more numbers, as I'm sure we will see coyotes, different tunes, etc.

But it will cost to 2k dollars for the manifold, TB and CAI so I don't know if that's worth it.

some people rather stay NA and 2g's is the price of a new set of wheels/tires its not to bad

I understand cause I'm staying NA but 2k on top of everything else I've done is a lot but I'll probably end up getting it. Ugh

well after the boss IM cai and TB your not spending much more...so an extra 900 for 15+ rwhp and some torque is not too bad of a trade off.

price will drop sooner or later

I already got boss IM and accufab TB and steedas CAI.

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 cant seem to find the Cobra jet manifold on tousley

What CAI are you using with it?

 

[kdanner]

What CAI are you using with it?

Homebrew. That's all there is right now.

 

[BLK2012GT]

Homebrew. That's all there is right now.

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