Dont add power to your RT or Scatpack without knowing this! 

I love my Daytona 392.. I have tons of fun driving it...never leaves me saying “ Mo Power Baby” 😉😀😀

No gimmicks , no click bait , no BS . Racer X only delivers helpful , useful, and his honest opinions from his videos . Cheers

Car modding is like a facelift you’ll never stop until your face is destroyed.

Your knowledge is amazing, I am a 5.7 guy,you always keep us involved in the channel , much appreciated !

You are the only RU-vidr I know that explains upgrading your car the right way to a T. Everybody else just tells you to do this and do that but do not tell you the weak side of everything else. I appreciate that you actually took the time to explain everything ❤️💯

I love my charger scat pack it had plenty plenty of power basically I’m leaving it totally stock should be fun for a long long time, I’m only doing some cosmetic upgrades to the car so thankyou for the input

Thank you Racer X, these matters have been on my mind, and you clarified this very well, and very rationally.. Tanks again..

Man, I just wanna say thanks for pointing these things out. So many people think they can just add power & be fine pushing the limits when this sadly just isn't the case. Like you said, this goes for any mechanical part, regardless of manufacturer. Only thing you left out was the breaking system. This too needs to be upgraded to compensate for the additional power & speed, but is far too often overlooked and/or taken for granted.

That's why I'm fully invested in my stocked Hellcat....Happy camper here....Save time n money....Points well made n taken Racer X!

Thanks big bro. Best advice ever from mods.

Love the little clip “that’s not how any of this work”. :-)

I love watching Racer X's videos. I just bought a 2020 Challenger Wide Body Scatpack in Go Mango with a 6 speed manual. Living in Keller, It's a great car and Racer X is responsible for me making the decision to order and secure this car. Thank you!!

Its going to be a while before I supercharge my 392 but I'm definitely looking into getting it tuned. Need more "passing" power 😂

"Comes with its Challenges......." Well it is a Challenger my friend :) thanks for the info brother.

Excellent video, nice job X!!

The 5.7 has come a long way from when it was first introduced. Dodge has pretty much refined things to the point to where its almost pointless to mod anything, short of cosmetics. If you want to step up in power, just buy the next best model up. At least it will have a warranty. And I know part of the fun in owning these cars, is creating something that the factory didn't have available. For those people, there's nothing to stop them, but the lack of money. And that, to me, is the catch. There's going to be a point to where throwing more money at that engine and set up, is going to become pointless. The only cars worth modding past improving headers, cams and intake, IMO, are the Hellcats. For those of us that love the Ram, we're just SOL. There is no 'next model up', so to speak. We are forced to take chances, since RAM refuses to make a muscle truck for us (the R/T and 'Sport' Crew Cabs, are a bad joke coming from the factory, requiring extensive modding from owners to be remotely plausible). But this is a tale, for another day... (cue the end music to Conan the Barbarian)

Wow a channel with common sense, good job

This is all accurate. I have a 392 with a procharger for a reason. All has been good but I don’t race it.

I got a builder/tuner he’s originally from texas but he stays in VA and goes back and forth to Texas. He has done a lot of hemi builds most or all of his 392 builds make 500-525 whp with cam heads ported intake and manifolds with headers. He also does his own tuning. He does all that work for around 6-8k 500 whp is enough to run 10s all n/a. His ig is mackbuilt

Thanks for an insightful video! Thats why I chose to keep my scat stock to keep reliability and told myself that in a few years (3-4 years) I would work towards getting a hellcat

Technology has definitely come a looong way! You can drop a bunch of money building a very fast car but there's always gonna be somebody faster than you reguardless of how much money you have in your car

You're 100% right about jumping into an expensive hobby , maybe make a whole video solely on wanting to own a fast car . I got myself into a 2011 GT500 @ 21 years old , knowing it'd be a costly hobby but never did I imagine to be spending the money I have . Clutches at $2,000 ... Throttle bodies at close to $1,000 , MT Street tires at $250 a pop ... I definitely don't regret getting into the hobby , I just wish I would've held off another year maybe to have a better grip on things . Many a times as you touched bases in this video do we hear non car people talk about slapping turbos , superchargers , nitrous on an engine and they have zero clue how much $$ in supporting mods thats gonna run them . Makes you appreciate things like Dodge putting out a car with 650/660RWHP with factory warranty

The one thing I really wish dodge would do is make the blocks aluminum. To make it faster you need more power or less weight

Sounds like they just need to just buy the hellcat if they want hellcat numbers😂

Once again you have taken a POINT and made many of us realize that it isn't as easy as just "modding away" without realizing that we must take into account things that might BREAK under STRESS of more POWER!

Beautiful Scat pack there Racer X! Just finished watching the video! I totally agree with you. The SCAT is already close to maxed out already. It's an amazing car for the money! I agree that you just can't throw power mods down w/o making sure the rest of the car can support it! With that, I'd totally be happy with a N/A 392 Chally! Have a great evening buddy! Thanks for the video!

The scat packs love cams. You put some pretty hefty cams in these engines and encounter no issues. The tuning just has to be good. When you see issues with the ring gap is is more on the lines of tuning that issues arise. The stock form is very durable you just need to find someone that knows these engines in and out. The 8hp70 is on the hellcat so it is rated for way more than 550 hp. The lsd and driveaxles can be easily swapped but will last a while.

I think these hemi motors put enough power for the every day driving on the road. There’s enough pedal there if you need to pass someone you can. No problem at all

Another great video Racer X 👍. Every time I think about a Procharger on my 5.7 Daytona I just think for the money I would spend I could just trade it in on a 392. Plus the other upgrades I’d need. LSD would be first on the list.

Your buddy, B Mason has repeated what you said many times on his live chats about the 392. He constantly refers to the ringland gap being to tight. He said it was for emissions. And he repeats how optimized they already are from the factory.

My goal is to go as fast as I can keeping the engine basically stock. It's gone 11.55 and I think there is an 11.4X in good DA. Had not heard the 15% rule before but will keep it in mind going forward. Thanks for the great video.

I absolutely love my 2015 Challenger R/T plus. In my opinion, its got plenty of power to get into trouble lol. Ive looked at doing some engine upgrades to my R/T but in the end I realize that there engines or 5.7 rather are just not designed to breathe like a 6.2 hellcat, there for once again in my opinion, I believe if I want to spend money on upgrading my R/T I'd be money ahead to sell it and find a nice used Hellcat, which I've seen some nice ones for in the mid 40k range. I payed 28k for my R/T plus and it has petty much every opinion available, but how many thousands of $ would I have to put into it and still not come close to the power of a Hellcat Challenger, and like you said, how reliable is it going to be?? Just some of my thoughts.. lol. Love you videos RacerX, keep up the incredible work 😉👍👍

There are a few things I would like to add. First, start with a plan. By that I mean define goals and figure out what you need to accomplish them. As stated in the video include the supporting mods in addition to adding power. Second, develop a realistic budget. What you're like to find is if you want to make Scat Pack power with an R/T it will take Scat Pack money to do it. Another disadvantage to modding a lower trim level is that the car will actually be worth less than the same car that is kept stock. Most people will find that it is more cost effective to leave a lower trim car alone and save the money you need to buy the higher trim level. The problem people run into is that once they're invested in a car they'll keep adding to chase a number or compete with other cars. Finally, make sure you keep some money available because more horsepower breaks things and often at the worst time.

Great video I appreciate all the knowledge that was given. I'm happy with my

EVERY VIDEO U MAKE IS SO OUT THERE, ITS ALMOST LIKE U GO TO BED TRYING YOUR BEST TO THINK OF WHAT YOU CAN POSSIBLY MAKE A VIDEO , I HAVE WATCHED A FEW OF UR VIDEOS. AND HONESTLY MAYBE ONE OR TWO , WAS WORTH WATCHING

Dodge is smart they trying not to make u upgrade ur 392 but make u buy the expensive hellcats lol

" That's not how this works. It's not how Any of this works "😭😭😂😂

Best stay under what ever the HP rating is for item... engine, transmission ect ........Peace of mind .....unless you have a race budget ...Lots of engineering went into this stuff and yeah they don't want to pay out warranty work........Great video sir

Great video brother, hope you save some folks the headaches of expensive learning. Keep rolling!!

After owning a Challenger Scat Pack Shaker for a year or so I agree with your statement that the Scat Pack is a capable car right off the showroom floor without having to add anything! I loved driving it, and it scared the hell out of me a few times!. I had to get rid of my scat pack last year and miss it... But I did get an older RT and found that the 5.7 with the 6-speed transmission is as much, if not more fun then the Scat Pack with the Automatic! BTW if you ever take the exhaust manifold off that 392 and look inside you will see that there are individual tubes for each cylinder like shorty headers :)

I think you are referring to ring END gap. Ring lands are the flat surfaces in between the ring grooves. You need larger ring end gaps if you want to use power adders because the heat causes the ring gap to close completely, and push upwards causing a ring or piston failure. The top ring on the 392 sits pretty high, not leaving much material there once the ring end gap closes. For nitrous or turbo/supercharging a 392, ring end gap should be around .025-.028". .006 per inch of bore for nitrous/supercharger. Hope this helps so people keep em together.

Excellent video

I think the 5.7 has forged pistons because it's a carryover from trucks built to be detonation proof for towing loads. The 6.4 they put cast pistons in to prevent people from buying the Scats for 25k less than the Cats and making a poor boy 6.4L Hell Scat.

An interesting thing I learned this week, apparently the 2018+ Scat Packs now come stock with the BGE block from the hellcat. I also didn't know they came with a forged crank. So the block is good up to about 1000hp. Nothing else is going to hold that power stock, but the block is solid. lol

Well hopefully I'll be good with my RT. Swapped over a bunch of stuff from the 392. Differential, intake manifold, cam, headers, and midpipes. From stock it's probably about a 70 to 80 HP difference all together. The RT had a lot of restrictions. Technically the 392 is a built up 5.7. However I'll be careful if I do a blower, however I may just opt out of that as that could be used for a down payment. I'll admit, when I upgrade to a 392 or a Hellcat, I may just leave it stock (I said the same thing when I got my RT, so I'm probably lying when I say that). I imagine that the next generation Chargers will be improved, not just in performance, but also build quality and technology.

I know I'm late to the party, but the 1 thing I hate is when a guy dumps a bunch of money into the power of their car but neglects the suspension and brakes. I love going fast, but I also love being able to stop as well as I can go. Subbed; owner of a '12 Challenger R/T

Mds and number 7 lifter failure.And oil pressure going with a hellcat pump. Mopar Drop the Ball. But tunning is key. And a pcm fully open and ecm. Thats what involved if go the deep forge inject and pump. Dod cam

Great explanation!! Adding too much horsepower will show you what the weakest link is for sure!! Thanks for the info!

Truth here... I honestly would love a blower that gives me 40 or 50 more whp. I dont need the 120 Magnuson claims. It would be great but yes... shit will break. My car is a daily driver and I would like a little more punch. Im not some ricky racer professional driver. Im a truck driver of 20+ years so this 5.7 is a fricken BEAST to me🤣. A solid 350-400 whp would be amazing in my book.

hey racer x! i want a drag pack for my '19 charger scat but was having trouble finding the wheels. could you link some?

Racer X : I’ve got my 2014 RT Redline . I’m trying to decide whether to invest and buy the whole Borla exhaust system from front to back with new long tube headers . Let me know

Fuck a factory 6.4. my timing chain broke at 75k miles, I just put in Mopar Crate 6.4 in my SRT8 2012 Jeep

Love ❤️ challenger..nice looking!!!

This should be given as a mandatory video to watch for every teen or middle aged hot rodder who has spent the bulk of his adult life in a Camry

I really use Tom like these cars! But now that it’s 2020 soon to be 2021! All dodge has done is made there boats into yachts! (Wide body) style! They look old now & played out! The only Cool part about a mopar car! Is that hellcat whine! NOT for its wheel spin! Lol cop cars is what the chargers look like! Unless it’s a SRT charger! Lol! To each his or her own tho! Also the interior lighting & design is old AF looking! Dash console air conditioning controls all looks old!

My scat Challenger looks like it's doing 100mph when standing still. Good nuff 4 me.

Drop in pistons, hellcat airbox, mid pipe delete or full exhaust with longtube headers and tune. Should get up to 500 whp good enough for me. Please Dodge bring back 426 7 liter hemi. for the scatpack or maybe the 440 ?.

Could i add a procharger to my stock Challnger R/T? if not, what do you recommend upgrading first?

R/T baby!! I bought a 19’ Challenger r/T and am loving it!! Check it out on my channel🙏

Racer X may have touched on this and I missed it but what about tunes from guys like Jay Greene? A 15 hp increase for 300$ or so seems worth it. Like I said sorry if I missed talk about this .

What about adding a bolt on procharger, 7 lbs of boost gains 225 hp on a scat pack. Simple! No tune no other changes!!

I drive/mod focus st (430whp/442wtq). its th same with these as well for th piston rings and top ring has smaller gap than bottom which causes alot of blown motors in these cars as well.

Is there a lopey cam / tune set up that will add around 50 HP to a 392, that doesn't require me to upgrade anything else in the car? Thanks.

Lots of great advise, where were you 30 yrs. ago LOL. Youngsters... please listen, he knows what he speaks!

Kept the stock tire size put Goodyear super car 3 Incan actually drive hard without skipping a beat

I love my 392 no need for more power. Its more than enough power 🔋. Great content my . Inspired me to go hard on my RU-vid Channel. Keep the great videos 📹 coming 👊🏿💯

I've had people tell me to mod my 392. I tell them, why don't you buy one, mod it, then get back to me. 392 engines deliver enough power for the average driver, I like mine just the way it is.

Smart man here to many people just chuck parts at it and wen it falls apart they wonder why hey this weekend I’m going twin turbo on my scat pac next weekend not driving scat pac thencar fell apart axels drive shafts it’s a expensive hobby you play you pay

You are my favorite review guy Racer X !! I own the 2020 RT Plus Shaker... Question, Power chip? Good or bad?

When i waz a teenager we had a 65ss impala n we were always adding stuff but ebery time we added for hp we broke something almost emidately. Bacc to the drawing board to figure out wut needs to b changed to work wit n for hp we added. It waz fun but fruatrating at the same time.

If you add performance parts you should tune your car as well

I'm gonna boost a 5.0, I'm starting with clutch and shifter, one piece driveshaft, once the engine is open I'll do oil pump, chain system, and cams, finally I'll do blower. I expect to spend around 12k to get that all done. Once I'm fast I'll worry about the looks.

Folks don't want to believe it, but it's cheaper to buy the high power car to begin with.

Man you're 100% right why even bother. Modding your engine isn't easy you have to cover all the weak points. I kept it simple. I just added a K&N intake some new headers a new throttle body and a tune for my 2014 R/T. These are minor mods I'm completely happy with.

You mentioned a key note for me. You said they squeeze out the most power out of them while still keeping them warrantable? Which is why my love/hate relationship with dodge. Ive know quite a few people with blown diffs in these cars and get denied warranty. Including myself. Just last week a buddy blew his diff on his 5.7 and like I told him. B4 he even took it to the dealership that he was gonna get denied. And what happened? He got denied. Dodge warranty is POS period. No reason why they pack all this power in the 5.7 and 6.4 and have diffs going out left and right. Then you say that the car was abused. Like how the hell they know how you drive that vehicle. Complete BS! Why buy a high horsepower car and have to drive it like a grandma! In dodge commercials all you see is them driving the cars aggressively, burning out basically driving it like it was meant to drive. But when something breaks. Its abuse. Bologna 💩💩💩

Real good information on my scatpack x man at 72 years old I love Driving my Scatpack if I need more Hp I'll be going to the dealer for that Hellcat I have a 1969 Nova SS in my garage with a 496 Dana rear end 410 gears guess what car I drive

I have a 2020 Challenger Scat Pack I just want add 20hp so what is the easy way to do that?

🏆Racer X 🏆 thanks for the ride in your 🍀time machine 👀✌️

Trying to find info ,where can I find after market cams for my 2019 dodge challenger sxt plus 3.6 vvt

I would to see a video recommending how much power we could add without high dollar upgrades to drivetrain and how to go about doing it for most bang for the buck??? I personally would be happy with 50 to 75 more hp without losing reliability

People don't understand, 480-485 hp is nothing to sneeze at. It's a scary ride. Fun but still scary

My local dyno shop says the 5.7 holds boost a lot better than the 6.4. I was a little surprised by that. They do all the various kits, but prefer the Whipple kit due to its better cooling.

I’am glad that you are educating passionate sport car enthusiasts about the limit in hp&tq ,you can had to your already fast car from the manufacturer.😎👏😎🌈

Great Vid! I see a variety of serious power adders such as twin turbos and ProChargers for the 392 and it’s tempting, but there’s way more to the chemistry than these parts alone. Like you mentioned, you have to do it right by beefing everything else up.

What can I do to my RT and keep it at the 15 percent to make it faster?

Not too sure why you even put RT in the title if the 5.7L is what you refer to as RT because you actually did not cover that. Seeing as how the 392 Scat Pack and the 5.7L R/T come with the exact same transmission the R/T owners have quite a bit of leeway in HP increase before the transmission is a problem. Now regarding beefing the rear, the automatics coming with an open differential is a problem, especially when it comes to getting off the line. Otherwise you covered the Scat Pack and your Hellcat and a Coyote engine, so you probably should have just left R/T out of the title. DC

You should have gotten a demon and beefed that up. Cheers.

Weight reduction is the best and cheapest way to mod a scatpack. Remove the rear and passenger seat and anything else you can lose and you just saved about 10k in mods. The best mod of all is suspension though so make sure you take care of that and you can be high low 11’s

Nope. Torque breaks things.

is the mopar cold air intake good for the 392

RacerX, what could I do to gain another 10 or 15 HP to my brand new Mopar crate engine 6.4, not to expensive.

Well I've seen people put whipples on 5.7, I want to do the same with the Durango what do you think?

This is why I like mustangs dodge scats are great daily driver but a mustang I can put a cold air intake long headers and e85 automatically 500+ hp dodge could never

Scatpack doesn’t need much done to it to be faster . I have a jay Greene tune , stainless works mid pipes and hellcat air box on my 19 scat charger . Making a lot more power than people think . 11.6 1/4 mile , 0-60 3.3 seconds .. does extremely well roll racing also . Modding the car is risky cause of the locked PCM , I broke my transmission after 200 passes , luckily kept my stock pcm .. denied all of dodges accusations (that my car was modded) and afternoon 1 month I walked out with a brand new transmission . Good video 🤟🏽

Hey man I just got a 2019 RT a few weeks ago and I love it. I wanted a scat pack but this RT deal was too good to pass up. I was thinking about adding some power but this is making me consider long term health of the car. Would an upgraded air filter and a really nice exhaust system such as borla be good?

Will this void my warranty?

Besides warranty they don’t want recalls

What do you think of a throttle body spacer

Scat Packs are cruiser cars that have power. They're not Mustangs or Camaros, they do not mod as easily. If you wanna race you need to save for a Hellcat. That's the main reason I wont buy a 392, I love modding cars and they just don't take to mods very well.

The top of the piston will break off. JS
