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

I tell you about some of the major drawbacks of adding power to the 5.7 liter RT and the Scatpack/392 cars. There is a big misconception out there about adding power to these cars so I wanted to touch on other factors to consider.

Absolutely my friend.. you have to look at the whole picture 👍

[@jerroldmalloy6881]

What type of cam and headers do you recommend? I like the different sound that it produces. The scat pack is fast enough for me as it is. I heard a RT with a cam and headers it was an amazing sound.

[@tomyunt1839]

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

[@gato8759]

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

[@RacerX9]

Yes horsepower costs money.. and the car hobby is definitely an expensive one

[@AJM0201]

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

[@RacerX9]

Sounds like an awesome plan

[@DJGRoc]

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.

[@ericgoer]

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 :)

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!

[@RacerX9]

Sovereign Knight .. for sure buddy🤜🔥.. love the scat on the street

[@robbiefrentz9427]

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

[@chadhanson4369]

I agree the specs would look good but just like the SRT 392 is faster than the scat pack even though the SRT is 200 pounds HEAVIER. With The same engine and same transmission Tests of removing 300 pounds makes maybe .1 sec difference The 1320 392 hemi is an 11 sec car. I don’t think less weight would make it as fast as a hellcat

[@RacerX9]

Yes I fully Robbie.. less weight would be great

[@robbiefrentz9427]

John Anderson Your correct. My comment was just to say if the ole girl went to jenny craig she could be much faster

[@evildrizzt1]

Dodge pays attention and learns from its competitors. Aluminum blocks have been tried in the past by both motorcycle and car manufacturers. Low reliability tends to keep these designs from going to market. Ironically, aluminum blocks are often used in race engines for increased performance. Often times these engines are used then discarded after each race.

[@BlargeMan]

@@evildrizzt1 Chevy has been making aluminum block LS motors since the late 90's and they're well known for their longevity and reliability. Don't tell me Dodge can't figure out how to do the same.

Excellent video, nice job X!!

[@pplebite8844]

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)

[@RacerX9]

All good points my friend.. who knows maybe the TRX will materialize 👍

[@pplebite8844]

@@RacerX9 The TRX looks to be a badass truck for the offroaders. I'm sort of excited for those that dare to challenge rough terrain. I see them from time to time over there just outside of Grand Prairie, ripping up the hillside. 😄 But for us guys on the street, not having a good muscle truck, really sucks. It's almost as if I'm exhibiting some envy for the Challenger and Charger owners. Well, yeah, sort of.

Excellent! Many people who get into high performance cars without understanding the content mentioned in this video find troubled times their way. Understanding this is protecting your pocket and your investment. Those who desire extra power need to listen up to these comments. Thanks! Caribbean

[@hu3.789]

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.

[@TransmentalMe]

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

[@jackasmaryan1776]

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

[@RacerX9]

You are absolutely right Jack 👍.. no question

[@jimgeorgeson6322]

Very prudent advice from someone who does things very well when it comes to their vehicles. Well done sir!

[@scottfarrar8661]

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.

[@Icipher4]

Such a spot on video. I own a 2020 charger scat pack. The car is so optimized from the factory. You gotta be careful and thoughtful if you want to add power. If I wanted more power I would have saved up for a hellcat.

[@SeamusMacMattain]

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

[@SaintStephen7]

So True! I'm building a Jeep Wk2 5.7 from front to rear. Solid build plus the braking, suspension, Drive train, ect...

[@JuanRamirez-wx3id]

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.

I agree with you on adding power to any vehicle. Just like when I started racing my Ice cream van. Started with just a camshaft and had no problems. Then added nitrous. Broke the driveshaft, then the engine mount, then a piston when I added more nitrous. Built new engine to handle 300 shot of nitrous. Broke the Dana 60 axle shaft. Installed Dutchman 4130 axles. Then the slip yoke, then the transmission , haven't had any thing break sense January. I still haven't turned up the nitrous above 250 yet.

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 .

My RT is now FBO with a Greene Racing tune. Learned over 7 months the 5.7’s are very bottled up and react to mods way better than a 392. Expensive hobby but LOVE IT! Be very meticulous and work with your tuner to have a bad ass ride but also keep longevity. Like you said, never take shortcuts do it right. Next mod will be a custom grind cam etc.

[@tomgrochowski9414]

Love this channel!!! Thanks Racer X!!!!

[@nkjellman]

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.

[@4-LOW]

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.

[@johnnykilroy9399]

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

[@wellingtonbruh3756]

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.

And if you think your a good driver, your probably not.

[@dbsdodgeboy]

Sent my 2015 R/T auto to OST Dyno for a cam and header and tune. Before that I swapped the open diff for a 3.09 LSD. The before dyno was 350 the after was 434 W.H.P., now I am done, just getting a converter so the car will launch. Excellent point about the HP870 vs HP890, I figure scat pack power from a 5.7L is the limit of everything else in the car. If I want to go more I might do the TH400 and Ford 9" or the HP890 to keep it street friendly. but that is going to be a $$$ build.

[@erictaylor1320]

[@hemiyachtcharger6538]

You dont need new pistons to make 500whp on a scat pack, watch omgitsmrmack dudes a legend

i have a 2010 charger RT super track pack r29 package .. this cars has over 222000 miles..no problem whatsoever my upgrades include 95 percent of mopar upgrades..6.1 intake..srt headers throttle body spacer, resonator delete flowmaster exhaust..catch can.. mopar CAI viper wide body wheels...diablo tune 93 octane 0-60 5 seconds 420 HP at wheels all bolt on 12 second car at track...the only thing i notice between the 392 and 5.7 is the 392 from 60 to 120 is a few seconds faster than r/t..BTW the 6.1 intake(expensive upgrade :)) if tuned does 15 to 20 more HP it sounds insane also get a pedal commander

I put a cold air intake on my Challenger Scat Pack and went from 485hp motor to 797hp..well I might have traded up somewhere too lol. My B5 Blue Scat Pack was a great car, still miss it, but my B5 Blue Redeye is pretty fun too

[@Jeff-ej4wp]

312 HP from a cold air intake? No way.

[@vf12497439]

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.

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.

[@RacerX9]

It's actually the HP90 in the hellcat which is far more robust. Lots of different cam profiles out there but by and large the larger the ring gap the more boost the engine will hold but there will also be an increase in blow by decreasing the engine life. The failure is rarely in the rods or the pistons themselves.

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

[@kevinruiz2535]

What do you suggest for suspension mod?

[@docholiday9513]

Kevin Ruiz very stiff drag racing springs and mopar sway bar kit if you plan to use drag strip but if you are on the street only then the same setup just not too stiff of springs in the rear but not to soft either.

[@docholiday9513]

Kevin Ruiz here’s a good example of fbo and cammed with custom suspension.

[@kevinruiz2535]

@@docholiday9513 thank you I'll look into the mopar sway bad kit.

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?

[@RacerX9]

bigalloyd .. absolutely my friend.. that won’t hurt anything 👍

[@bigalloyd]

RacerX thanks for the reply boss. Great videos 💯

[@19rt83]

just got 19 rt as well & going to the same to it

[@19rt83]

been thinking about a 274 cam but now i’m not sure

[@shawne7228]

A 5.7 would love a centrifugal blower, and it would not make too much horsepower to hurt your transmission. If I had a 5.7 that would be what I would do

[@rickbradley5373]

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
