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

[@cuhyote5435]

I agree props to them not inflating the numbers

[@kevincandelas1228]

you gain little to nothing with a ported throttle body.

[@RealMopar574]

@@kevincandelas1228 yeah, some intake manifold porting companys are offering a “monoblade conversion” as an up-charge during the porting process to get rid of the twin TB inlets on the actual manifold moulding itself.

[@saidtheblueknight]

They didn't inflate the numbers, but they sure deflated the numbers of the GT and Mach. They also forgot to mention alot of the gains for the CJ cars were due to the tune. If you slap on a basic tune on the Mach it will probably make more power than the CJ. But then Steeda wouldn't be able to sell the CJ or their airbox if stock Ford parts made more power.

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.

[@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.

[@11secondeclipse]

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.

[@midnight347]

A ported cj with a mono is king. You will max absolute max na power with a cj. This is why all the fastest na cars run cjs. You need cams to truly take advantage of what they can do.

[@11secondeclipse]

@@midnight347 yes if you are going Max NA it might be worth all that money but with cams too. My point is that if you are utilizing the stock cams, like most people, buying a Ported Boss with a 90mm TB gives the same results as a Non Ported CJ with a twin and I’d like to see that exact back to back test. And the Boss setup is a lot cheaper and looks better too, imo. Same power curve and steadily pulls hard from 4K- 8K rpms. and then it’s ready for boost later too. They are both high rise intakes with similar power curves. The bottom of the intakes are identical.

[@EscortSportage]

I love my ported gen3 intake. Don’t planning on spinning 8k or more at the moment so I think the gen3 is best for me.

[@Oatis_07]

What’s the best manifold for a “21 Mustang GT”?

[@dalelockett2619]

Why does the new FR CJ manifold have the bridge in the TB inlet? Did Ford design the EVAP\PCV port(s) in this new CJ intake manifold to come out behind this bridge like the old 4.6L OEM 3V intake manifolds so that the EVAP fuel vapors & unmetered air will evenly mix\distribute into the incoming air thru the twin bore TB thus plenum\intake runners? IOW's for better emissions compliance? This is the only reason that I can see this being done..............

Not too surprising that there isn't a big change, they did say that the reason why they redesigned it in the first place is because they wore out the injection molds for the original CJ intake. Instead of getting new molds of the same old CJ, they took the opportunity to give it a little bit of a redesign. Looks totally bitchin too!
