6.4 HEMI MODS!! ALL the BEST MODs you NEED!!

Everyone wants to know what the best mods are for their car and engine. People have different price ranges and budgets to be able to work on their car to make it perform the best that they have to work with. In this video I've tied together 5 of the best mods (In my opinion) for the average Joe who wants to do a few things to improve the performance of their 6.4 Hemi without breaking the bank. Most of these mods will need a tune like stated in the video for them to work well or at all! So keep that in mind when doing these mods to your ride!
Feel free to leave your comments below with feedback and I'll do my best to reply! Thanks for watching!

[@TakeDeadAim]

I build engines for a living. I've built and rebuilt hundreds of all makes and models(mostly V8). With only rare exceptions, catch cans do nothing but CATCH your money. I've torn down newer Hemi's with 100k+ miles and the intakes were clean. Keep your oil changed...with a QUALITY oil of the CORRECT viscosity and you'll not need one with these engines. Some of the older LS's NEEDED them but not really a "Hemi" problem due to their design and single valve design. It's "easy" to make an 11 second car...but that extra second will cost you a LOT of money and time. Most bolt on mods do very little over OEM design. Hemi's do NOT run a "Lot" hotter than other engines. Who makes this stuff up?

[@Lilshad843]

👀

[@flicksifyr6793]

5.7 Hemi. Added a catch can at 95k and at 105k i switched out the 5.7 intake manifold for a ported 6.4 manifold. I run fuel cleaner in my car every couple fill ups so my intake valves were pretty much spotless. But the old manifold and the intake runners in the heads were very caked up with oil I could only assume from the pcv valve. Regular oil changes, never more then 3,500 miles at the most. Whether the catch can works or not is up for debate, but to say hemis dont get gunked up with oul from the pcv is not true.

[@Somethingisntright64]

Right. I thought those PCV valves had a check valve. If the check valve is not stuck open it shouldn't suck oil into the intake.

[@7s29]

Love my 392. It's an engine for every occasion.

[@fullsend5437]

Couldn’t have said it better myself

[@solomonstello]

It's the one I want. I want a Daytona 392.

[@user-kf6fl5if4k]

Sweet car, great vid. Nice to see the mods that’s the joy of owning these cars.

[@BigMack392]

An oil catch can is an absolute must. Most guys think that it's only needed for a direct-injected engine which the hemis are not. But that oil mist going from the PCV valve back into the intake is going to bake onto the intake valves and eventually degrade power. On my 392 I drain away about a 1/8 cup of oily fluid out of the can every 2000 miles, and that's just with street driving. Any aggressive driving will produce more blowby and more oil/water vapor out of the crankcase venting system. So go get that catch can kit and install it as soon as possible.

[@enerrivers4392]

Actual & useful information, thanks big guy. It makes sense.

[@dustins4275]

“The last modification is to loose your sleeves, takes off instant weight from the driver” 😂🤣😂 just kidding man good video and great tips!

[@lmjames33]

I also did the mopar intake and it uses the open headlight and the air coming through the hood scoop. There is a tube that runs under hood from hood scoop to the top of airbox. When you close the hood it seals the box. Best intake I've had.

[@geoffreydarnell6899]

Just picked up a 2018 392 Dayton. I would love to put the basics on it but I love that warranty. Hell of a video man, just subscribed

[@richardcaballero681]

that's my dilemma too.. I have a '19 392 RT...great warranty however I maintain my cars very well to the point having a warranty is useless unless I have a lemon. I already have the catch can, hellcat intake/throttle upgrade, no problems. In the works on getting that Borla ATAK exhaust and a tuner, not sure which one to pick though.

[@planelander]

[@ThreenaddiesRexMegistus]

Good useful info , thanks!👍🏻 Nice car.

[@ThreenaddiesRexMegistus]

Got myself a 2014 300C SRT8 and love the big-ass refined brute. Fantastic engine that 392 and just effortless even in standard trim. I’ll never get to drive near it’s potential but it’s fairly interesting on launch assist.😁👍

[@robertrichards6760]

Great tips. Will definitely make these mods. Already have cold air intake, but it's open and need to add heat shield. The 2018 daytona 392 already came with a upgraded exhaust when I bought it. Thanks again

[@TheQuarino]

I did a 90mm BBK Throttle body and JLT CAI and had a custom tune done at Richard Petty's garage. Before tune the car dynoed 417 RWHP after tune 430 RWHP. 13 RWHP gain for about 1,000 bucks not bad,I definitely say it was worth it

[@nlmbquan5124]

Only 13 gain for $1000 I rather put that towards a project 5.0 and gain more horses

Well said and thought out. I've done these mods to a LS Vette along with long tube headers and not much happened until I got a dyno tune then, WOW ! So yes these mods work on all engines.

[@phillipdale6765]

Thank you for the info ..very helpful

[@MrKclo42112]

My cai is open its a k&n but it seals real tight once the hoods closed .a 180° thermostat makes the whole engine run cooler too. Your best point is tuning . I agree 100% all the bolt ons in the world wont do crap if the cars not told theres something different .diablo helped me a bunch .

[@caliwryder2507]

Your doing good with the videos man. Been subscribed since the first video and glad to see you gaining subs and hope more come. Keep up the good work! LOVE the scat pack btw. Wish I would have gotten that color instead of sublime green.

[@DBlockKTV]

You’re a grown man. Learn the fucking difference between your and you’re.

[@sergioiniguez9743]

Great Video Brotha 👍 Subscribed. Only thing I don’t agree with is the after market exhaust, that’s 1k-2k you can use for something worth it. (Like a Cam or Drop in Forged Rods & Pistons) Stock Cats and 3” Straight Pipe all the way thru is all you need on the 392 (Electric Cutouts if you want to burst some ear drums) Some people got more money to spend 🤷‍♂️ but the little power an exhaust adds is killed off by how much it weighs.

[@devinbobki7369]

Very good video man!

[@kingofhearts_392]

You are one of many people that inspired me to trade in my SXT charger Nd get my 392 scatpack

[@TownBoSs510]

Great choice

[@mattcarafa210]

I think the active exhaust on my 2016 scat sounds incredible, down shifting with the 6 speed gets the snap crackle pop that's awesome. I'm planning on getting the twin snorkel 2019 hellcat hood that has functional ram air tunneled right over the air box + mopar cold air that has the gasket to bottom side of hood.I really like the destroyer grey, would like to get a 6cyl awd charger in the grey for my commuter car, that way I would stop driving my baby back and forth to work racking up 80 miles a day.(just can't help my self, it's hard to go back to a hamburger when you got a taste for steak)

[@martinm2921]

Driving a bone stock scat pack. The only mod is a short throw shifter that was on in when I bought it. Rides like a champ. Would love to do some subtle mods like this but, its really running like a top as is. So, I'm happy for now.

[@williampabon6432]

Thank you great info. Subed

[@fobbitoperator3620]

It's funny when I hear people knock performance intake & exhaust investments. You may only receive 10-20 hp gains, but the throttle response gains you get gives you immensely explosive access to aaaaall that hp you already have. Add to that a high flowing exhaust, & you're shred'n tires in such manners that would make John Force peanut butter & JEEEEALOUS! Smart video brah!

[@christianfender6499]

You and Risa eggs are the only ones that break the point by point what you need to do thanks

[@mikepoint4983]

Very informative video , I own a 2016 scat pack and would love to ad a catch can , but when you speak of a “ Tune” does that include the transmission ? and does tuning a transmission make any difference . I’m getting back into the car seen and most of these mods I have no or very little experience with . I’ve been watching video after video which is helping me get a list together . I know wider tires help these cars put the power down as these cars came with a narrow tire . Cheers

[@ArtemisLockedIn]

Just cause I saw the name "Artemis" sitting over the engine I'll sub 👌👌👌

[@jalhellcat1114]

Nice Job...

[@Sooper_B]

I agree on the tune and Dyno is a must. So many people buy mods and never Dyno with no proper tune and have less HP than stock.

[@RedEye19]

How does one end up with LESS HP than stock just by modding ? And the Dyno is for people who can afford to fix something that Dodge WON'T cover under warranty.

[@hellcatredeye-g6582]

Just for the scat pack I’ve had many Mopar’s anyway catch Can is a great idea

[@frosty6.471]

Which wheel and tire setup do you have if you don't mind me asking

[@cj0146]

I have a 2021 daytona 392 with a factory mopar cold air intake; definitely sounds better than the factory air box and increased air flow; I ported and polished my factory 80mm throttle body with an airaide throttle body spacer and got better dyno numbers than my buddies 392 with an 87mm throttle body with cai. People talk crap about spacers but I definitely feel a tremendous difference.

[@DERDM]

Would a time be needed from a ARM drop in filter? Or could I just disconnect and reconnect the battery?

[@jaymay5457]

I have a 15 challenger srt392.. ran a 12.5 at 111 stock..... budget mods are diablo pcm and tuner, mid muffler delete, cat delete, 180 tstat, hellcat intake, ported throttle body (easy), and an email hemifever 91and trans tune. After the mods I ran an 11.8 at 116mph..... (no seats) about 730 dollars into it.

[@scottandrews4822]

What about rear end differential gear changes?? Going from a 3.09 to a 3.92 would be a big difference in acceleration. I have a Ram 1500 Hemi with the 8 speed and 3.92 locking differential (a must) and have surprised quite a few folks. The only other mod it has is a K&N filter. But seriously - gearing makes a difference. Also, if the driver loses weight, that helps :)

[@tundrawhisperer4821]

Could you tell me the specs you ordered your Billet Tech. oil catch can with. I like the look of yours. Are those braided hoses with it? Thx

[@CaptMaxz]

Yo what exhaust or tips do you have? I just got a 2017 Challenger Scat Pack and not a fan of the rectangle exhaust. I love the way it sounds already so yeah I'm not looking for anything aggressive.

[@visa8versa]

Good video, just bought 1. Scared asf of it. Will probably do the catch can first. Then a intake. Honestly I'm coming out of a 3.6 into the 6.4 and it is nothing nice.Can I ask who and how much that strutbar cost? That red and grey with the name is 🔥

[@terrylewchanin36]

if the stock Throttle body is replaced what is the mounting area size? Wouldnt that be the bottle neck in the whole cold air intake?

[@ryann7754]

Where did you buy the hellcat intake and the modified headlight that goes with the intake box?

[@vegaswould]

I've been told that an oil catch can by some people is bad. Even though your intake and valves will gunk up, they're cleanable and it still lubricates the top of the cylinder walls. I still use a catch can on mine, but what are your thoughts? Have you heard about that before? Also, do you think a 2mm throttle body port would do anything without a tune?

[@bigdaddy3927]

[@jessehopkins5774]

My 2018 Scat pack charger pushs about 510 to the wheels. Mods list -legmaker intake -billet oil catchcan -borla atak cat back full exhaust system - tuned for 93 octean ( soon gonna be tuned with diablo Predator2 for E85 ) - MSD coils - will be adding 4”” aluminum drive shaft to go with the michekys (Very soon a whipple 2.9 supercharger going to the beast engine bay - I should be pushing close to 800 to the wheels after getting tuned )

[@InnoV8Official]

The tune adds the most untapped power in my opinion. That supercharger will be badass! Just make sure to forge out your bottom end!

[@allentraylor5659]

#1 .In-line mufflers are FAR less restrictive than multi-chamber mufflers... #2. THE LARGER AND COLDER THE AIR INTAKE , THE LARGER THE "COMBUSTION" CYCLE..... MORE TORQUE/POWER .

[@adamdavis2760]

That's a good list, the only thing i would add to it is a 180 degree thermostat Heat is the number one enemy of any engine. Kicking your fans on at 180 instead of 230 is going to make your car run much cooler therefore it stays in the power more consistently and prolongs the life of your engine. Also A good thermostat runs you any where from 30 to 50 bucks so they arent expensive

[@solomonstello]

Thanks Adam.

[@DarkHorseParatrooper]

Except... they've tuned the cars to operate in a certain temp range. If you read the SRT owners manual, they tell you this. The hellcat for example, it's peak performance operating temp is about 220. I'm pretty sure the SRT Engineers know more than you, me, or anyone on youtube...

[@loganschardt21]

Question do you ever have to empty the oil catch can?

[@twistymcslide2]

AEM's cold intake is the best ive used/seen on dyno . it relocates the IAT out of bay , into the fender well , comes with extension wiring and all , i see 2-6 deg f + intake temps than ambient temps . think its only for the 5.7 , but may be for the larger engines . and or is easily modifiable .

[@ImperialUprising]

I have a cold air intake that DOESN'T have a cover on the top. But when I close the hood, it fits perfectly and seals it. Is that okay? Also it sucks in air from down below kind of like what you got.

[@michelerjgross7339]

So if it runs hot why not swap out the thermostat for a cooler one I know in some factory publications from days of yore said to swap a 180 degree thermostat read later things saying the same would that be a logical mod at least to make the other mods work better due to the cooler temps?

most mods do effect without tune however will not give the >maximum< gain without a tune, ECMs have a range and are not fixed......

[@donniechaffin6897]

Exactly right. For example, I've read where the Hellcat airbox and a dirty filter will give you the same flow rate as the stock airbox and a new filter. The sensors and computer will work out these variances and you'll get adequate flow all the time with the Hellcat airbox (and probably many other CAIs). Why would you need a tune for a oil catch can? Until my car's warranty has expired, I'll stick to things I can undo.

[@Random_guy803]

Catch can is a must. Best mod for 392 is a pro charger tuning kit ! For around 8 grand you gain 200hp on a stock engine. Comes with a hand held tuner or you can take it to the shop and dyno!

When you get a high quality Cold air intake when you put the box in a in the bumper is a air scoop that leads right to the top off the intake what you can do is get some adhesive heat sheild and wrap your cold air intake box on the outside keep everything inside cool also seal the bottom with it
