Testing the New Cobra Jet Intake Manifold | Gen 1 vs Gen 2

You have all been asking and we have finally been able to test the new @FordPerformance Gen 2 Cobra Jet Intake Manifold on our in-house dyno versus the Gen 1. We tried it on our 2022 Mach-1 test vehicle and compared it with a stock 2021 Mustang GT. Thanks to @Lundracing, we got a solid tune and eliminated as many variables as possible when testing. The tests with each manifold were all done on the same day as well. Check out the results and let us know what you think!

Props to Steeda for not trying to inflate numbers for some sales👍 good video. Ported vs Ported Monoblade conversion for the “Gen 2” CJ might be a good one

[bardstables]

This is why I love you guys. You back up all your stuff with real numbers. I am a bit surprised though. My 20'mustang GT made more horsepower at the wheel stock than the Mach 1 did at 412. After I installed the CAI and E85 tune by you guys in just shy of 470 at the wheel. For anyone that doesn't believe me the proof is in the videos on my channel. Now I'm making more than a stock Shelby GT 350. You guys nailed it!

[Elver_Galarga_jugo]

Love the honesty and transparency. You guys could have inflated numbers a bit to boost ford's ego. Love you guys and LR for doing these tests and doing them right!

I would like to see a comparison of the all 4 of the manifolds in this test on a car with a full exhaust system and running on E85.

[XCVi_MAC]

I’m running ported 18’, p mas, full E85 with full corsa exhaust LT’s. I’m happy.

[krayzjayfpv]

Cool, I’m glad it’s back. Thanks for the testing.

[jamesyoung]

So realistic even the Gen1 CJ has the ear broken off and plastic welded back together haha.

7:15 I’d love to see a Ported Boss with a 90mm TB Vs the CJ without porting and a twin TB because I feel they would be the same numbers and the Boss setup is so much cheaper. Nobody ever did that test with the ported Boss. I feel the CJ isn’t worth all that extra money unless you’re going full max effort NA racing and money doesn’t matter and it’s not worth it unless you do cams too and at that point you might as well do the Ported Boss with an ESS blower for a fun daily car. The Ported Boss deserves a real comparison.

I was trying to find this out two days ago. Thank you

[NITROUSnBIASPLYS]

Please do a ported test 18+ manifold then ported & gen 2 CJ manifold then ported 💯💯

[ThrottleHavoc]

Thankyou for the comparison, I would definitely love to see a ported gen 1 vs ported gen 2 cj with free flowing exhaust. That aside, I feel the stock Mach 1 and the stock gt run should be taken with a grain of salt. Those where stock runs, so in addition to adding the cj, the tune was more aggressive than the stock runs. The cobra jet definitely will carry power out to 8000 the best, but this doesn’t show what the 18 and 350 manifolds can do when they are tuned more aggressively as well. Also when comparing the stock gt vs Mach 1, being that they have different factory tunes and one is open air intake I also don’t think that’s a good comparison. The Mach 1 definitely makes a good chunk more power in stock form, but I think it would be fair to get an aftermarket tune for both and leveling the playing field to truly show the difference in the manifolds.

Great test, just goes to show how good the standard mach 1 set up is

[liamwhitbread]

91 octane, mach1, American racing long tube headers, Gen 2 intake manifold, performance cams, corsa exhaust and steeda intake

[oh_johnny]

Both manifolds ported with long tube headers and e85

[Kaulpenney]

Love to see this can’t wait for mine, I’d love to see a mono ported gen 2 that’s what I will have with p51c and some corsa headers

[bradleyisofficial]

So it fits under the stock hood now 🤯🎉

[tylerphelps]

Would’ve liked to have seen the gt350 pulled higher tbh.

[crodrcable]

Prior tests have shown that the best all around manifold is the stock Gen 3 manifold ported. And the cost makes sense.

[oh_crazy]

Has the ported test came out yet? Nice job Steeda! 🔥

[shoeboxchris]

Mix it up more, longtube heades obviously. Add in an aluminum driveshaft and Steeda rotors on back to lessen the rotating weight.
