Every Mustang 5.0L Bolt-On Part Dyno Tested Back-to-Back! Intake, Headers, Ported IM, etc.

For any performance car, modifications become common for a reason, right? As it turns out, that's not always the case with 2018+ Mustang GT! In this video, we test nearly every common bolt-on modification for 2018+ Mustang GT, and share the raw numbers from each. Spoiler alert: one of the most common does absolutely nothing at all. Which modifications are worth the money and effort? Give this a watch to find out!

[@jimcarney4896]

My 19 GT on 93 did in fact (bone stock) avg 3 pulls 403RWHP on a Dyno Jet. Fantastic vid, actually gives answers to those questions ALL of us wanted to know BEFORE spending our money. The fly in the ointment is the JLT result. Hood open, accurate. However with hood closed - way high -really more like 9 to 13 RWHP. Worth mentioning P51 cold air system ~ $250. It actually does JLT like dyno #'s with hood closed. Again-fantastic video 👌👌

[@Texas_Road_Warrior]

I think with a closed hood the JLT would’ve made the same as the stock intake pipe… not to mention it would probably drop trap speed considering it’s not a sealed box VS the factory box ram air at high speed…

[@thundorkat]

@@Texas_Road_Warrioryeah those “cold air intakes” do absolutely nothing. Maybe a larger intake tube but closed box does the job just fine.

[@midnight347]

​@@thundorkatif you're flowing more air you need an intake. The open filter with a decent heat shield isn't that big of a deal. Temps may climb some in the pits or sitting in traffic but they go down very fast once you're moving. They flow more than stock and that isn't really needed until you're flow9jg more air than stock elsewhere like ported manifold headers or even cams. Then it benefits you alot more. All the mods work in combination with one another. There are closed box aftermarket intakes if you're that worried about it.

[@hassaan89]

Wish y'all did a 93 calibration before doing the intake to show the gain from just an intake (yes, i know intake is minimal on it's own, just wanted to see a number)

[@FranMonajGuitar]

One of the best vids I’ve seen on the topic. As pro as it gets!! It should have thousands of views! I tested my 2016 gt on the dyno to know the baseline before I make all the changes. It peeked 381 hp. Is that common for a stock 15/17? Now, I ordered a 2018 manifold, cold air intake, 91/93 tune (7900 redline) + tune device all the parts by vmp. I have the original catalytic converters + x pipe and muffler delete. Should I be expecting 430 hp similar to your stage one on the vid? It’s pretty much the same: cold air, 18 manifold… and I guess the tune Should be similar for 93 gas

I like these bolt on dyno tests except one thing. I’d be interested to know how IAT’s change the results. Dyno tests are always with the hood up but that’s not a real world test. Especially with closed v open filter boxes. Keep the fan running but, close the hood would be a better actual test.

I was looking at doing a 93/E85 tune on my Mach 1 and a MGW shifter install. Both of my tuners that I interviewed suggested not to do E85 unless I do ceramic coated cats or no cats because it will stop them up over time. I ended up just doing the '93 tune.

[@wesd2845]

@@semiautoshooting1734 if you have a manual transmission I recommend the MGW shifter. Also, I learned something new at my tuner. This tuner went to Ford Performance advanced tuning School and creates his own tunes and has been doing it for 15 years and as always booked out a month. I was pulling 4-6° of timing on the dyno and he asked me what kind of gas I used and I told him Shell and Amco/BP. To my surprise he told me that's the worst gas that I should use because it has those additive cleaners. Shell uses v power and AAMCO BP uses invigorate. He said that causes the gas to burn at a hotter temperature and it tricks the engine into thinking something is wrong and then the engine goes into safe mode and pulls timing. He recommended to use off-brand gas with no additives and just throw in some Lucas octane booster. He said to stay away from all gas that has those additive cleaners because he said they don't really clean much anyway and by the fact that I have a JLT catch can I'm not going to be needing much cleaning anyway

I'm not sure if yours is a 21 or 22 Mach 1. They added a hydrocarbon trap to the 22 and 23 Mach 1s inside the cold air intake which decreases 18 Wheel horsepower. You can remove it in 30 minutes. If yours is a 21 Mach 1 you don't have to worry about it
