😂😂😂 this kid is a legend in his own mind.
Thank you!
@@HellcatGuy gotta believe in yourself first!
He forgot to add that stickers add 5 hp. Each!🙄
Cold air intakes don't show any hp gain on the dyno
😂😂
Everybody that doesn't have a 6.4 suddenly has become a 6.4 supercharging expert.
The complication with supercharging a 6.4 is the fact that it has higher compression ratio. It can be done but would need to be tuned to run safely. (You will need to be tuned for boost anyway if you add a supercharger). I would recommend running it on e85 with a flex fuel sensor.
Also aftermarket superchargers that out perform a stock hellcats can be found for a cheaper price.
Where can I find one??
No you need to forge your piston and rods. Else you'll only run as high as 8psi on your S.C.....hellcat's come forged. Your welcome
@@Momoshiki2379 I was talking about a way to get it to work on a stock unopened block. E85 and correct timing will prevent the knock that will make the weaker rods fail. You are right though about doing pistons and rods for more reliability / higher power potential. I would spend the extra and drop in pistons and rods.
@@larryp85 agreed..my fault family...I say stroke it 426 or 448...trackhawk friends(hellcat) are cool. Build I respect a built vs bought. #1320boyz
which after market superchargers
A cold air intake giving an extra 30 to 40 hp? This guy is definitely A forum master technician. This guy is definitely new to the game and has just read the boxes for the horse park ganes. It’s almost sad to hear this guy talk about this stuff.
Are leg maker intakes legit?
@@HellcatGuy I heard jlt series 2 is where it’s at in terms of quality and power. Mine definitely helped.
He lucky if he see any gains from a cold air intake.
You can't super charge a stock 392 because you'll blow it up. It has different pistons and rods than the hellcat. The piston rings are very close to the top of the piston to help it run cleaner. Boosting this engine will destroy the pistons.
Oh
Forge your pistons throw all type of hp at it. 392 have the best potential. Don't sleep on the 392. My bro got a 15 with 1400hp to crank...1100whp...392 forged engine. Not hard ,not expensive
@@Momoshiki2379 but it’s a forged engine, and it’s not cheap to get it fully built
you can supercharge a stock 392, you just have to have low boost, caps out at about 7lbs
That’s like saying you can’t boost a 350z you’ll blow it up
I would like to see some dyno results on your mods, especially the CAI. I doubt that it provides 30 HP by itself.
you need a tune too
I talked to a speed shop and if you follow RacerX you'll know none of these mods except for the supercharger add any true hp for the money. Coldnair intakes reduce IAT and don't give any hp, chips are junk and exhaust would really do little more than increase sound. I have a 2022 Challenger RT 5.7 6 speed. It is gonna be around $20,000 to forge my bottom end, cam, new ECM, long tube headers, clutch, duel hellcat fuel pumps and dyno tuning to get me around 900hp. Definitely consult a shop before wasting money on RUclips suggested mods.
@@HaulinBass are you getting a SC as well
@@Jumpman0509 yes. The Whipple 3.0
The camshaft goes under the vehicle huh? 😂
About to drop the Legmaker in the Hawk🚀hon be insane. The whine is already loud in whatever mode, but I can’t wait to hear post LM. Always good stuff bro!!!
Brooo I literally ordered a leg maker for my hawk last night! Vid coming soon
I think he’s over estimating the gains with a CAI and exhaust. Also ,6.4 will only handle about an extra 100 hp with the stock bottom end. You would also have to do something with the trans if you go full boost. The 8hp70 that comes with the 6.4 can only handle around 600 ft.lbs of torque.
@@seanmarchiny how did you get that power and how much did it cost?
@@seanmarchiny agreed I just recently did a similar build with my 392
No, Stock 392 handles 950 hp. Read this somewhere the other day, I SWEAR TO GOD I DID!
@@STORMRIDER_OIF_06-07 I just read it too, I think a motor trend build article but they quoted a guy from Arrington
@@oakvalebob glad someone besides just me read this elsewhere as well! Ty for the confirmation....
Never heard of a camshaft that goes underneath the vehicle…😂. Mine is inside my engine, but you know I’ve heard on Mars they’re going to be on the roof.
This! I was looking for this comment!!!! 😂
Need pistons and rods for supercharger ring lands on stock pistons are too thin end up cracking. And borla over flowmaster
Be prepared to blow your motor, transmission, or differential soon after though.
The Grand Cherokee Trackhawk, Jeep has bolstered the drivetrain (transmission, driveshafts/half shafts differentials, transfer case) made some engine alterations to account for packaging constraints, changed up the cooling system(lost the fog lights to help cool the oil and air feeding that massive supercharger), and retuned the brakes(bigger and 6 piston Brembo's all around) and suspension.
Those are just the hardware changes. Add to that all the validation testing-which FCA engineers include a 24-hour on-track durability cycle and a punishing high RPM/high load track test wherein the Jeep had to undergo five 20-minute hot laps around a racetrack at temperatures greater than 100 Fahrenheit.
All backed with a warranty.
Just get a Trackhawk 😂
I totally agree with u, this kid doesnt know what he is talking about, some poor person is going to follow his advice, put on a supercharger with a cam and destroy their jeep SRT and wonder why it happened. Also, wasnt the SRT engine block itself NOT designed for so much HP? Where the hellcat engine block is reinforced for 700+ HP?
Brownbear is probably right, but to FullSend's credit, I was seeing some tuners claiming they were able to safely run with 4psi long term. I wouldn't wind your supercharger up to 8+psi but it sounds like there are some gains staying at the bottom end of the boost range without adding tremendous risk.
I have no doubt by doing any supercharging that you'll shorten the life of your engine and drivetrain.
Didnt you hear me say this may void your warranty or do damage to your engine if you don’t get the right parts to support it?
@@MrDTraffyes about 8psi Whereas the hellcat motor boasts 11.6psi (14.5 on the Redeye) reliably
@@HellcatGuy sorry no I missed that.
So why wouldn't you tell people all the parts to support a build like this then? Instead of saying it may damage your engine? I mean your video is advising people how to turn their SRT into a Trackhawk shouldn't you outline all the advice? And properly too?
I enjoy your videos, but I would suggest doing your research before giving out mechanical advice to people about their vehicles.
Wow! I enjoy discovering my dream whip😋
I appreciate the advice I needed this info
I have a srt Durango what mods are proving to give u gains in hp?
I have the afe gt momentum you can definitely feel the deeper breaths the engine takes aswell as a little power increase the sound it makes is also very appealing gotta say I’m pleased w it
Nice! I have a Legmaker on the way
What the camshaft does "spins while it drives"
The camshaft does NOT go "underneath the vehicle", as you say. Don't you know what the camshaft does and where it is located? What are the cam specs and lobe separation angle (LSA) on this "Chopsticks" cam and who makes it? How do I buy it?
You NEED to upgrade the transmission to handle the power. Stock 6.4 transmissions are only rated to ~550 hp (I don't remember the exact number I read but I know it's not much more than 500 hp) the cost to upgrade to trackhawk/hellcat power would be more than just trading in for the upgrade.
Please give part numbers/vendor/costs/specifications on your parts list. For example, how do I get this "chop sticks" camshaft if I want to order it? I woukd think that these mods make 30 HP all TOGETHER. It would be nice to go through each mod separately and test it as you go. Some of these "improvements " can SLOW your car down if not done properly, especially on a car that is so factory optimized like the Scat and 'Cat.
I have the afe cold air in my Jeep an i love it it def feels betta than stock…but i have a hellcat to so i don’t need to mode my Jeep lol
I was thinking about either AFE or Legmaker for my trackhawk… thoughts?
"The camshaft goes underneath the vehicle and it spin as you drive"
Well, i mean I guess lol
This was the exact comment I was looking for😂🚩
😹😹😹😹😹
People that talk about engine parts should understand what the engine parts do.
I went with an awe touring non resonated exhaust and it sounds really nice I will have a clip on my channel pretty soon
I’ll definitely stay tuned!
What is the part # on the performance camshaft?
You can also upgrade the throttle body…
Whatever you do don’t supercharge your 392 without upgrading the internals. All of the internals. Don’t half step or you’ll be very angry. They didn’t make this engine for boost. They made it for Naturally aspirated horsepower.
Throwing a 6.4 In my dodge Dakota hopefully after I get the engine and put these mods on hopefully these mods work out
"Camshaft spins when you drive"
Perhaps
Borla exhaust system sound great!
Cold air is only good for 3hp
15hp*
** 0 HP without a tune
i got 8 hp
A cold air intake can provide a modest increase in horsepower ranging from 5 to 15 horsepower, however this depends on the maker, as some may even rob you of HP, so make sure you get a well known make that has proven it product.
Would u or do you have all of these mods on your car?
You need forged internals if you are going to boost it
I put on some stickers that I bought from autozone and got at least 100 hp. I'm gapping pontiac aztecs now.
Dude the cam goes under the engine wow I always thought it went inside the engine with a correct tune. And nooo nothing from the hellcat engine will fit the srt…. But I did put a sticker on my car that’s easy 25hp gain 🤘
Tell me you’re NOT a car guy, without telling me you’re not a car guy.
No cold air intake adds 20-30 hp without a larger throttle body, and tune to work together, a cold air intake only adds 5-7 at most if not add in the real world
So I’m not too familiar with the details. What brand would you recommend for CAI? Also performance chip?
“ my scat gonna beat hellcats now”
Yessir
I'm supercharged now with a forged 392 hellcat lifters and injectors. And I'm just over 800-900 you can't push 700 wheel, tranny rear end fuel pump fail can't handle more then 700
I put on a Borla Atak. I recommend the Borla .. sounds amazing and zero drone .... Jeep SRT has ram air coming from around the fog light. A cold air intake doesn't seem to make any gains. Another channel ran it on a dyno with and without ... Save $500 and get a high flo air filter.. Will get about the same gains...
I have one an yea I notice a sound it sounds very Good
So will you get the red key if you add the mods
Yes of course
No forged internals? You seem like a nice kid but this is just a recipe for scattering engine parts all over the ground. If you wanna throw a supercharger on your motor without going into the engine, get a 5.7. Smaller displacement but was made to handle boost in stock form. The 6.4s are made for naturally aspirated power in stock form.
CAI, alone? No. TB, high flow cats are just a few things you need to do with that CAI to even come close to the gains you're talking about.
On that note, my 2020 Scat is supercharged (Edelbrock). Motor is stock. BUT...I'm running low boost. Because these guys are right about the internals not being able to handle high boost. It. My plan eventually is to take it to a 426, so I'm gonna run I like this as long as it will. It will be a good case study.
The Edelbrock 2650 is a very nice unit. Do you have any dyno results?
What are you smoken? So, I put an intake on and it just 30 HP. HA, without a tune??????
I’ve always loved chopstix
Keeping the supercharger aside as this a whole complication in itself, all the rest combined if done correctly along with a proper tune will give you a 60 to 70hp max to the wheel on a 6.4L. And you forgot to mention the catless downpipes. The catalytic converters on those do limit the power and removing them makes a difference.
You know how big of a difference? I'm contemplating buying these brand new ones from this guy for 350 today
@TRICKYBYRD sound wise it is night and day. Performance wise together with cai and a tune you can expect something like 25 to 30 hp
I have the aFe GT intake that I put in a 2015 Jeep SRT two weeks ago. Honestly I don't hear any difference from stock but it did drop my intake temps. The butt dyno didn't pick up any HP difference. I think the CAI tune might make the difference here. I'm considering a Diablo Tune next to see if the car hits some new butt HP.
That’s interesting, would you say it was worth it? The tune may be the difference maker
@@HellcatGuy Assuming it changed absolutely nothing performance wise (which I doubt), it looks so much better under the hood than the stock intake. It took about an hour to install, so for me it was worth it. I'm at 5800 ft of altitude so anything that helps the car breathe is worth it to me. My list of next mods is a catch can (I know) and looking at a Diablo PCM. We all want that supercharger life, but we'll keep knocking away at these 20 - 30 hp upgrades.
Yeah that makes sense. It defiantly looks better under the hod! Think you'll ever supercharge??
@@HellcatGuy I'd love to eventually. I wouldn't want to crank the 12psi the hellcats do, but since I'm in Colorado, I'd love to just get 4-8psi just to remove the negative impacts of my DA.
Ah okay. That'll be a crazy build!
Bro added 300hp with just $1500 on amazon 😂
I've actually done all these upgrades long tube headers cold air borla atak. Stage 2 camshaft and tune and it wasn't 800 hp lol and it wasn't even close to 4k
Gassin ppl up to wreck their whips 😂
You can do all the mods to make the equivalent hp as a trackhawk/hellcat,but the running gear -suspension etc upgrades will cost wayyyyyyyy more than just buying a Trackhawk!!

"I've got it BAAAD, got it BAAAAD, got it baaaad, I'm hot for teacher. OOHHHH...oh yes I'm hot!"
Nice video but more research needs to be done! Some of those numbers are a bit inflated! 5.7 and 6.4s don't have forged Pistons so more than 10psi of boost is a super no go! 2.7 red eye blower's on a stock 392 bottom end would be the absolute end my friend 🤣.
So my camshaft goes under my vehicle.....
Say less fam!
Hahahahahhahahaha
If u want to be safe jus upgrade your pulley, intakes & exhaust & jus run 93 .
Camshaft go under the vehicle and spins when you drive.🤔 🤣🤣🤣🤦🏽♂️
Bro I have no idea what I’m talking about
@@HellcatGuy it’s all good bro 😂
The cam doesn’t go under the car it’s in the engine
Imagine the engineers at dodge discussing why not to supercharge the 6.4....."It can't be done, the engine is just to big"....."Sorry guys, it's just going to be to hard, we shouldn't do it."
My god lmao “the camshaft goes under the vehicle and spins when you drive” damn this guy is knowledgeable I’d def take modding advice from him
Thanks!
Bro 💀 exactly what I was thinking I think homie thinking of the driveshaft lmao
An air intake will not give you 40horses 😹😹😹
he forgot the forced internals, if u forgot the upgrade on those rods, you're toast especially with a supercharger
Really just buying hellcat supercharger and install it for $200 and bom you have a hellcat 😂
The cam shaft is for the valves kid. That was embaressing
Insurance is a big added expense for the hellcat
YeaaaaNO.... 😂
If your going to make go fast make dam sure you can stop too
Young fella definitely needs to talk to pros before posting useless information on his channel. Gonna cause someone to waste money and possibly blow their car up. Love the enthusiasm though.
30 extra hp for a cold air intake? lol
Kid read an article on basic upgrades and thought he’d make a demon
Kid is smoking 🚬
Awesome idea’s
Thanks man!
Lost all legitimacy when 1. Was CAI...
Fucking Rookie!!!
😂 please do these mods and let me know what happens
Might as well just get the Trackhawk 😪
I think you need to learn more about what a cam shaft is and where it goes 😅
Man if these HP numbers are correct everyone I have seen dyno the cold air intake, changing the cam or put a tune on an STR get no where close to the HP ratings he's stating. Also, super chargers dont like high compression thats why the Hell cat is a 6.2 liter and not a 6.4 liter.
Yeah only way to do this is if you got 30k to blow. If you get a scatpack you know what you're getting so if a person want more power just buy the hellcat.
bro your talking about a driveshaft that spins under the vehicle. thats not the cam shaft lol
Don't need to do that have a trackhawk man hahahaha nice try tho 😅😂😂😂😂
You're not getting 30hp from a intake. You're lucky if you get 3hp from a cold air intake. You'll need long tube headers and a tune to see real gains
This guy is killing me. Doesn't have any mods on his vehicle
😂😂😂 this guy
Had to turn the video off when he said the cold air intake will get you 30hp😭
Your not getting 30hp from a intake, you might get 5-10hp if lucky, I added a intake on my srt Jeep and charger scat, on my hellcat the intake helped a lot more with the power and the whine of the supercharger.
Leg maker says 30, is that true?
@@HellcatGuy no lol no intake will get you 30hp, you would need exhaust, intake to get close to 30hp, it’s easier on a boosted platform with getting more Hp on small mods over an n/a motor.
Fuuuuuck I think I installed my camshaft wrong I had to open up my engine to install mine
It's funny he says 6.4 Scat Packs are 475hp but they are actually 485hp at the WHEELS. In the system it pulls at 500hp total at 6000rpm. Lol...Scats are already 500hp, 485 at the wheels.
Holy shit my guy, did you say the camshaft is under the car and buying a performance chip on Amazon is a good idea? Jesus Christ man.
That’s not true 6.4L can handle way over 700hp they build the car to handle way over 470hp some cars come with 3.7L touching 400 and still boosting handling the power.
When he said the cam goes in the bottom of the car I stopped listening. Cam at the top engine, crank at the bottom. A 2.4-2.7 hellcat blower can be found used for about 2k-2400. 5.7 hemi can bold it right on n maybe be able to take the power. Factory 392 NO! Do not buy it for your 6.4 engine. The factory piston are weak and can not take that extra power. He did not mention changing the pistons and crank. You will eventually blow your engine from this guide. The whipple is okay and the mmx bolt on supercharger yes. Do not do these steps. I’m rebuilding a 6.4 and have learned the difference in performance parts vs the 6.2 n 5.7
He said 30HP 🤐
400000000 hp
"The camshaft goes underneath the vehicle" Bwahahahaha! Completely clueless.
Ok so your wrong on basically every mod you talked about, hp gains are not that high and the price is steep. No CAI is getting you 30 hp maybe 10 if that and tuning late model hemis is like $2k alone. A cam might cost $1000 but the job and other parts adds up to $4k-$5k and is such a big job you should do headers while your there so add another $2k-$3k. Exhaust is basically sound only, not much power there and flow master sounds like crap. last supercharging the 6.4 is not reliable unless you pull the bittom end to open up the gaps on the piston rings otherwise youll pop the ringlands (very common). Also to do a hellcat blower would be a pain in the ass and more expensive than a kit. You sound like the guy that goes to the exhaust shop with a cherokee and wants it to sound like an srt.
Sorry but a cold air intake nets little if anything. This is really bad information.
30hp from an intake? Try .3
Yeah but the 6.4 won’t be as reliable as a supercharged 6.2 which is the hellcat engine because the 6.2 has a forged rotating assembly and the 6.4 is cast
6.4 hemi has a forged crank. Just not rods or pistons.
6.4 hemi has a forged crank. Just not rods or pistons.
6.4 hemi has a forged crank. Just not rods or pistons.
You can supercharge a 6.4 just fine. If you are worried, just buy forged rods and pistons... Then you basically have a stronger and better engine then the 6.2
30bhp from a CAI? 😅
I'm sorry but the information provided is incorrect. To be exact very incorrect. In order to get a scat to hellcat or track hawks horsepower you'd have to do work on both the top and bottom end. Just adding a CAI will not increase your hp unless you have your car tuned after the install. If you don't your cpu is not going to recognize the change. Then you'd have to do long tubes swap out the throttle body for a ported hellcat throttle body, port the air intake and heads, upgrade the fuel injectors to a min of 650, upgrade the valve springs, add a snake charmer aka torque converter to the Trans, then fully forge the internals before you can even add a supercharger. Then you'd need to cam it. So if you do all that without the supercharger and go the naturally aspirated route you'd get up to 670 to 710hp which is more than a stock hellcat at the wheels.
you cant just put a supercharger on a 6.4 lol not that simple bud
Well it kinda is.. Specially a procharger, it's not hard, a guy with a mechanic mind can easily do it in his garage
Upgrade pistons you’ll be able to ppl boost 350z like crazy handling 600hp
& the most important part before doing all this. Drop in piston & rod s cause if u gonna blow ur engine 🤣
