Top 5 Mods Not To Do To Your Ecoboost Mustang

Easily one of the worst and most misleading videos I’ve seen on the eb. Providing no evidence and just ones shitty opinion. Maybe at the time of this videos the stock cai might have been better but not now. Cai, borla downpipe, mbrp cat-backs with a tune, gained 110hp and 125 tq. Exhaust sounds deep and not like a ricer. I’ve had these mods on for about 20,000 miles and haven’t had one problem.

Am I the only person who thinks Ford should hire Yamaha again to make the ecoboost a crossplane to give it that excellent V8 tone?

I cracked up at first when he said, unless you're doing meth...", lmao!!! I mature so hard!!!

I agree for the most part except for the CAI. Depending on the CAI. Going from stock to the shelby GT350 CAI intake and tune (the tune doesn't work with stock air box) made a dramatic difference. According to 224xLC dynojet made almost 90 hp at peak gains and almost 100 tq at peak gains. IMO CAI is worth it if you buy a tune and intake specific for one another together.

The intercooler part, dude, did you black out for those two minutes? I've had both sizes from a stock location intercooler, to a big FFTEC unit with a Garrett core. Barely any difference between the units. Any stock sized replacement is a huge upgrade from stock and one of the best mods you can do to this thing. Super cheap on the used market also.

I had a cobb accessport v3 stage 3 no issues at all. Mods I ran on my eco was a full mbrp exhaust, jlt cai, cpe exhale kit with a cpe intercooler. Loved that car only reason I got rid of it was because I didnt want to upgrade the turbo. Great car absolutely loved it but now I have a gt, time to mod that

Well I just installed the roush cold air intake in my ecoboost, and I've noticed significantly more power vs the stock box. No tune

When you first hit the gas, it kinda sounds like a diesel truck. I love the loud turbo sound :)

Most of your advice really applies to the 3.5 ecoboost taurus and lincoln as well. Intake does nothing but add a louder turbo sound. The stock ford intake is not a bottleneck. At least not yet. Aftermarket exhaust rasps like crazy, but does add HP. Definitely go with a custum tune from a reputable tuner like Unleased or Livernois.

Find a better flowing exhaust system, not a louder one. That sounds like shit.

You WOULD, however, want a cold air intake, with a larger inlet pipe, IF you go big turbo. With THAT you’ll see gains. 👌

This is an older video so may have changed but I installed the Cobb stage 1 93 tune and love it. Car has a lot more power but more important drives and shifts better. Now I bought the car to drive 10 more years so not out racing it.

At least he owns his mistakes and passes on his findings on to us!

You won’t lose power with an intake upgrade if you add a tune. If anything you will gain power in upper RPMs.

There are certain caveats however to his "suggestions" which I feel should be expanded on, and I am not saying he is wrong, just adding to it. 1. Cobb AP OTSs are listed specifically for the mods you "should" have and you should not be running anything higher than a stage one without any of the supporting mods, these tunes were done by cob based on their parts, so unless you are running similar AND the correct octane. Get a custom tune, but I ran the OTS tunes on my EBM which was more than bolt on (big turbo too) and I did not have any issues, and no knocking, so I would just leave this, your octane may vary. I would not be surprised if he is getting gas that is less than rated and does not know it, its very common. You should be running a knock count PID and Octane adjustment PID of some sort on your tuner logs to confirm knock/ping values are withing normal states. 2. Throttle body spacers (not w/bung in the spacer), or larger throttle bodies are pretty much only good if your running a big turbo or methanol. (note there is also a 70mm Ford Racing TB available as well, but if you not running 29 psi+ its uselsss). The Intake spacer is only good if it has extra injector bungs for secondary port injections or methanol. Making the runner length longer will only move the torque curve lower in the range but its negligible by adding an 1" It is siimilar to what happens when you add a cobrajet intake to a coyote engine, same effect, you the runners are actually shorter and it moves the torque curve higher in the RPM so you lose torque down low but gain it higher in the rev range. The TB spacer thing is more about adding turbulence to the air flow to help with atomizing air fuel better and it is kind of useless if your not spraying a power adder like NOS or Methanol. 3. Most un-boxed and open CAIs do not improve performance unless the tube size is greater than stock but often take a air temp hit being open to engine bay heat, if not tucked into the fender. IF you get a full Airaid or similar intake you will make similar power to stock but that is is, it looks cool and nothing more. I personally like the extra noise of an open CAI but I like it tucked in the fender, or like the GT350 intake were you get the best of both you get a larger inlet, better sound and same if not better performance over the stock unit. Losses and gains are not high enough in most situations to make it noticeable as shown by one of the last engineering explained videos on this, something like + - 2-3+% 4. I totally agree on the exhaust portion, no strait pipes without a resonator and even then I am way iffy on that. It is hard to get the sound right. Borla ataks are great, loud with a good growly rasp and no drone, and I would not even run a non catted DP with those.... Everyone likes MBRP race cat backs because they provide similar gains and sound to Magnaflows comps at less than $600 for 409 stainless.... It is popular for the bang for the buck crowd and are attainable by most people, where as dropping $1500 for just a cat back is hard on the mod wallet. FYI I lost 4PSI of boost due to running the stock resonator on a larger turbo with a down pipe due to restrictions, I would remove that restriction as a first mod even on a stock EBM you would gain better performance even with just that and a decent tune. 5. I ran a mishimoto intercooler with my large turbo and had no AIT issues it maintained a healthy 10 degrees lower than stock under full load, and was good up to about 465HP without any heat soak issues, however everyone should know that heat soak is an issue with all ICs if you are not moving, its how efficient they are with air flow that counts. Large front mounts are always better but you may have a cost of the Active grill setup to do it, so that should be kept in mind, and also remember that the larger volume of the intercooler is often followed by a small loss of pressure too. You will gain better temps at a slight loss of boost pressure. So make sure your tuner is good. I would add a 6th mod to the list and that is billet water pump pulley. you will find its very hard to find a full set of lightweight pulleys for the EBM and doing just one such as the water pump pulley from MMR or whomever will net zero real world gains from dropping a tiny bit of rotation weight from the drive system. I would also add to that the process to do pulleys can be incredibly complex as well as you have to lock the crank in position etc. which required work front and rear of the motor to do full pulleys anyway and the price and time/labor to performance gains (Unless you pulled your motor and are full bore forging your block) is just not worth it, you are better off pulling the balance shaft instead for a real world 20lb drop in rotational mass weight. =)

I wish I knew all of this when I started doing my mods

Can't go wrong with the magnaflow competition catback

CV Fab units are very nice, just installed the street version on mine. Made a nice difference with minimal invasive modifications. It really depends on what you are looking for doesn't it ? I may go to my local 1/8th mile track once or twice a year to play and make a handful of passes, that's it for me. No hot lapping or constant beating on my car so the street intercooler should be fine for how I plan on using it.

I really don’t know what to do for my 2020 Eco Mustang. It has the active exhaust and I think it sounds all right, so maybe just the intercooler upgrade and let the rest alone? This is all new to me, wish I could find a local shop that could be one stop for any mods.
