2020 Dodge Charger, Headers and intake + Dyno 

great work as always LHT! love how you do the extra dyno pulls with different setup because i for sure am always curious to see the gains... Thanks for all you guys do always!

What a perfect spec!!! Love the blue on the exterior and the red and carbon inside!

Great video! Very thorough. It’s good to see how much actual gains we can get from these modifications.

Great video guys, love the before and after dynos

I want to point out how good this video is, very detailed, great quality video and most if not all the important information is there. A lot of times I look around for videos like this about parts that I want for my car, but there never is an actually good video about them so I appreciate good material like this.

You guys have the best work ethic! Keep up the good work, its nice to see a scatpack on your channel.

I love the format of this video very systematic subbed

Well done vid that was fun to watch love the comparison runs as you did the changes. Thanks. The dip at around 4800rpm as mentioned below is the variable intake runners activating, Can't really tune that out with the stock intake. Performance page dyno on my '18 SP is fairly accurate and it reads crank HP, not wheel. The next easy thing to do on that (besides a tune) is to clean up the intake manifold and put a true 84mm or 85mm throttle body on it. After that you are pretty much tapped out with doing tuning.

This is the best dyno video for any car. This is the shit we all wanna know lol. Cool to see what the difference in parts make in power

That dip is when the intake manifold switches from long runner mode to short runner mode.

John I’m back, I was looking at scat pack vids and find my self back here again love it lol

Great great video. Thanks for doing the one at a time runs to show how each performs.

Great video, very good job going through all steps while also giving information. Awesome job!

Fantastic job!!! I enjoyed the incremental steps on the Dyno so we can see what each modification actually does to the cars numbers. Please do more videos like this? I just ordered my Charger Scat Pack in "go mango" orange. (There goes any chance of it being a sleeper!!!)

really glad i found this channel!

Just want to echo all the compliments here - know it's a lot more work to shoot and perform these multiple interstitial dynos but makes.for an awesome video!

Great vid like always. Iam think that better was to do first air intake test :) . Its much easier to back for stock intake later. U will be have data from 2 intakes with stock exhaust. Next change exhaust( u have already mounted aftermarket intake as second run with stock exhaust) and than just change intake for stock . U will be have full perspective where are restrictions at :) . Great job guys :)

Very nice video. I just bought the same car in a 2021. Love this thing.

Finally an honest video with clear speaking people with real information. 👍👍👍

I really appreciate the way you guys did this dyno test, one piece at a time. It's especially frustrating when ECU tunes are not tested separately. Somebody does a dyno run after doing intake and tune and they show 25hp increase . . . probably 20hp or more due to the tune alone, but there's no way to know w/o testing separately.

I own a 2021 daytona 392 with slp loudmouth catback, Factory mopar cold air intake blue filter, throttle body spacer from airade, and ripp supercharger coil packs with ngk plugs; Putting down 465 to the wheeks.The stock headers for the 392 are tremendous for shorties. Unless you go to long tubes don't change them out unless you wanna waste money for no reason.

Great spec on this car. Sounds great too

The factory headers are basically short tube headers. Waste of money for just 10 HP I would’ve gone with long tubes n tuned. Good looking car tho and good clean job guys.

Always enjoyable to see how much each mod gains.

The JLT filter is made by S&B - they’ve been around a long time , they’re definitely not part or made by K and N . The screen for the filter is mostly for water protection. The difference between the scat and hellcat hood is the Hellcat hood has 2 openings in the hood on each side of the scoop so the JLT package for the Hellcat comes with a piece of plastic to half cover the heat extractor hole in the hood and then the filter sleeve is just an extra layer of protection if water gets in. Great video guys

Nice video. That dip is actually the active runners, in the manifold, switching from the long ones (bottom-end torque) to the short ones (high RPM HP).

Great video, beautiful car!

That color scheme is on point .

This charger is nice. I am definitely liking the widebody style very cool

Very informative video guys👍 thanks for sharing!!!

super good video i have a 2009 challenger srt8 found the information very nice.

Nice video. Pack with Good info too 👍🏽👍🏽

Nice video getting longtube headers, JLT intake, throttle body (idk what size yet), and a 93 tune on my 2018 scatpack this year. So definitely worth seeing some of the gains

Good stuff. There’s a RU-vidr on here who made the same who 450 with just a mid muffler delete and hellcat intake.

I love this video. Great job.

love it when u guys test mods on the dyno. i'm wishing you could do more of the same for honda all motor

Best sounding charger I've ever heard

good video.. thank you for the comparison test

I love 1500 dollars worth of 12hp mods

Really cool video. Thanks guys!

That's my favorite color!!!!!😍😍😍😍

Beautiful car

Great vid! Thanks for the info!

Great job 👍 fellow's 💯 , really good information to know 💯💪🏁

Outstanding Vic! Kevin...

I hear English,German English, and southern accent in one ... lol. What’s going on there? Nice video also!

Awesome video!

would love to see more videos on this car.

ID LOVE TO SEE WHAT IT DOES ON A TUNE

That dip is from the runners opening in the intake. Dam this makes me get shorty headers to replace the 6.4l & a afe CAI for my 5.7l 20whp is not bad for no tune, fkr an actual bolt on .

Really great video!

Someone finally tested the dyno chart in the vehicle finally

BEAUTIFULLY-spec'd 392! Rarely see this color combo on lots, which the customer most certainly special-ordered. I agree that the headers aren't going to give the type of gains the owner may be looking for, instead needing long-tubes w/ high-flow cats(noticeable power gains with those two). Getting rid of the restricted exhaust with some Borla ATAKs would add a few more ponies and even better sound. Still, I LOVE what this owner is up to!

Awesome video thanks for that

I wonder if porting the exhaust port could unlock more power? Also a ecu tuning to tie it all together. Soubds good too with just the header plus stock exhaust.

I had a similar finding on my 5.7 using the BBK shooters with round ports on the D shape ports. I ended up going with JBA headers because of that so the ports match D to D. I couldn’t get a clear answer as to if the circle ports would be ok with the D shape.

Great job nice videos

Gorgeous car. Watching now.👍 Edit - Great video, guys. The big Dodge sounds tough and that shade of blue with the widebody looks sharp. What were the results using the "sock" at the end? That reminds me of those filter covers that my buddy used to have on his 4-wheeler back in the days when he raced. Like George mentioned... keeps the water out. Loved the video as always. Have an awesome weekend, guys.

Great work

Liked the video interested on how much power you would have added when adding a catback exhaust

Great video. Subbed

Great video! Im glad that you guys listen to customers and what they want, unlike other places that will just tell you what the dyno place wants to do and not the customers, it seems that there is lots of haters no matter what brand of cars you get, youtube is where all the haters are engineers, master techs, performance parts designer's to every brand ever come out and knowledge of every car brand and even know more than the person doing the dyno🤔, I give credit to this person using his car to show what HP &TQ #s you can gain with this parts, its his $$$ and chooses to do whatever he wants with it, there is one knuckle head saying that he should have gotten a hellcat...... Really!? If someone gets a 4cyl then is crap, get a 6cyl then is crap and should have gotten a V8, gets a V8 and then 😒 oh should have gotten the one with the supercharger, haters who's car is this? Not yours hater so just keep your mouth shut! Anyway sorry for the long post but this crap gets annoying.

Love That Blue 💙

Nice gains 💪 👏 👌 👍

Flow stepping is now known to be better than port-match that's why the headers are round. The larger port makes a step down, the dead space after the port creates a area of low pressure that the flow wants to fall into naturally pulling the flow one way.

If anything the red sock on the filter looks good in the engine bay

Great thorough job on videos!!! 👌👍 Especially on covering the product be installed and comparing stock-to-aftermarket. Does this trim model require premium fuel?

Good job 👏

Glad i found this.

I’m from Florida also!! Yesss

I use an Aem dryflow sock on my hybrid racing cai on my 8th gen civic si for hydro lock.

Man I need that carbon trim for my 2018 BADLY

You guys complaining about the headers are dumb. He cut down Under hood temps, gained 10hp across the entire curve, better sound with no rasp, didn’t have to get a tune, and kept his brand new cars warranty. Plus 90% of you don’t have any mods and can’t afford them.

Lmfao went up 10 horse power and 4 torque, people swear they put a cold air intake and it turns their Honda into a Bugatti

I just saw the video with the blue widebody charger, do you think if a larger throttle body was installed it would help make more power

I thought is was hellcat but it’s a scat pack btw the car looks beautiful

Great job. Really informative. How close was the dyno to the dyno on the car tech pages ??

Looks good.

Love the fact the factory 392 manifolds are 1-3/4 primaries with a 3" outlet (factory cats have 3" inlet to 2.75" outlet) and the Hooker are 1-7/8 primaries with 3" collector. Getting a 12whp gain without a tune on stock cats is impressive. I think one of the reasons Hooker used round ports is for the anti reversion effect on the D shaped cylinder head exhaust port during cam overlap. That and the larger primary size and collector design helped too. Would love to see this car tuned with HP tuners and back on your dyno for a final comparison. Great vid guys!

The red truck is clean 👍

Gotta love it 👍

The dip on the dyno is where the intake manifold changes from a short runner to a long runner

Not knocking the owners choices at all, this is all personal preference. My son has a Widebody Scatpack Charger also. He was basically told by other Scatpack owners .”Don’t waste money on shorty headers you already have them, and don’t buy a 300 dollar CAI just get a Hellcat Box and filter. And you’re good.” So plus parts, labor and dyno time I’m guessing over 1,300 dollars for 23HP? Hmmm. Beautiful looking car though this is the color I wanted my son to get lol . Great info good video!

So was the new gaskets oval or round didnt show them

Fun to watch

Great dyno testing the different mods guys! Did the performance pages dyno match the actual rear wheel dyno numbers?

Too bad there isn't really room to make some long proper headers. Solid gains for a couple bolt on parts. You think it would make some good gains if you port match them?

Intake sock really doesn't do much besides keep debris and some water out to save your MAP sensors. The 370 intake seems to have a lot of issues without it and the GT350 has shown some longevity results by using them. Also at the track it helps on the K&N S2000 filter to keep stuff out too. Not really worth it on a street car unless it's a 370Z or the 2015+ STI's (but stock is best for those)

Have any problems with blowing head gaskets?

Well done. Jlt filter is S&B. S&B filter are higher quality than K&N

With a r secret intake and long tube headers with dyno tune how much horsepower will it get my 2010 chrysler 300c hemi LHT performance???

Awesome video! This is what I was looking for.. what bolt on power can one make without touching the tune and voiding your warranty! I am doing the same on my Daytona 5.7.. it already comes with the mopar cold air intake from factory..but want to replace the log style exhaust manifolds with jba shorty headers. Seeing that the 392 gained 10 rwhp and 10 rwtq across the rpm band going from factory shorty headers to better shorty headers.. the 5.7 should gain the same or more going from the cast iron exhaust manifolds to actual jba shorty headers.. that coupled with my 3.09 gear swap should make for quite a bit more fun.. still retaining all the reliability of the stock car! Can more power be made..yeah.. but it comes with the cost of lower reliability.. and these cars are awesome from factory just the way they are..

I have a dip like that on my s2000 that the tuner couldn’t work out after installing an urge header. I can actually feel the dip which comes around 4500...

Header slip in and bolt design should be standard in all v8s. Thats fantastic!

I remember when I bought my 88 Mustang LX 5.0. It was stock at 225HP and I gained 40+HP with simple mods 1. K&N intake 2. Timing up to 14 degress 3. JBA shorties 4. SVO H pipe (catless) 5. Flowmaster 2-chamber mufflers Car sounded great and it was running in the mid to high 13s - which was quick for the day - versus 14.6 stock. 40HP on a 225HP motor is significant gain. Adding 25-30HP on a 485HP motor doesn't seem nearly as significant

How about intake, TB, full exhaust, ported manifold, headers, tune...THEN dyno. :)

The dip I believe is the active runners switching from long to short runners @4800 rpm.

Can I ask how much this ran your customer $ wise? Great work and very thorough! thanks for the vid!

SOunds sweet and raspy on the fly by

The filters by jlt are from s&b
