Cleaning the intake manifold is scary, not cutting the map sensor. Anyone who ever installed a stereo system can tell you that ain't shit. Good details and info on your video 👌
I just drove 12 hour round trip for a 6.4l intake lol! Since guy didnt ship. Now i just need to port it, so my 90mm TB fits & order the Runner port module so they work.
@@rene8312 no I still haven’t officially got it tuned. Long story but my email tune is supposed to compensate for the intake, but it really needs to either have a dyno tune or a revised tune made from data logging.
@@n-power-automotive I see. How much additional hp do you think it will make once it gets tuned. My understanding was as much as 18. I have an 06 Charger Daytona I'm making some upgrades, as well.
The top end gains are 10 to 15 without tunes. The midrange is where the true gains are. I saw 35 to 40 from 1800 to 4500. I also ran a year without the srv hooked up. The Z Automotive srv kit is the way to go vs the MSD. Adjustable in the car, and won't fail due to heat under hood.
I’m sure with long tubes and a tune it would help a lot these things such as a cold air, intake, throddle body, long tubes, ect give you a little extra power but all of them together plus a tune then will add a lot of extra power
Yes I agree. I was surprised. But I bought the car used so it had 40k miles of use with no catch can. Regardless I’m glad I got a chance to clean it out while I was in there.
Great video I like the way you took the time to explain the. Hold process , what is the name of the MSd box that we need to do this mod I know there's different kind of MSD boxes which one is one that you're using to complete this modification I'm looking at doing the same thing to my 2010 Challenger having a storage ever since I bought it I don't use it because I got cancer but I still like to tinker. Thank you Robert
Nice video. I have no automotive background, so please forgive the question. I noticed that you felt no significant power boost with the swap. Does your engine have "eagle" cylinder heads? Could the lack of significant power be due to the alternator or cam? I am trying to learn since I just bought my first Dodge, a 3rd gen Dodge Ram 1500.
I don’t own this car anymore, but it did have Eagle cylinder heads. They started in 2009. Cam and alternator were untouched, but it wouldn’t have anything to do with that.
It may save some time if anyone is doing this, go buy a $10 multimeter from Home Depot/Lowes/Autozone and you won't have to trial and error on the ignition switched wiring.
Did you reuese your old throttle body of the 5.7? and how about Short runner valve (SRV) actuator (05038529AC); Short runner valve (SRV) wiring pigtail (68064996AA); MAP sensor (68271094AB); PCV Valve Cap (05038532AA); Did you have to exchange this parts also or could you reuse the 5.7l parts?
Why did the seller sell the whole setup? Was he unhappy with it on his vehicle? I am unfamiliar with what you have done to your engine, but you really need more mods to make use of the 6.4 intake. All you basically did was lay groundwork for future mods. With the 5.7, you'll need to stroke it, add a camshaft, or both to make use of the extra capacity of the bigger intake. Do you have any plans to dyno your car for some hard data? On the injector wires, the common wire (the one that all the injectors have - brown/yellow in your case) is a common ground. The different colored wire for each injector will be a signal wire - the one that sends a positive pulse to open the injector. You will need to tap into the colored wire instead of the common ground for signal.
Hey thanks for the great questions and suggestions! The guy who I bought the 6.4 intake manifold, MDS box, etc from crashed his car so he was parting it out. As far as mods go, I have pretty much all the bolt ons but no internal mods. And while a cam or stroke would absolutely give me way more performance out of every bolt on I’ve done, the 6.4 intake manifold is supposed to give gains in TQ across the low to mid range RPM band. It’s been proven on many 5.7s. That’s why I’m suspecting I need a better tune based off of a data log. I haven’t planned on getting it dynoed, not to say I won’t someday. As far as the injector wire goes, if you watched the whole video at the end I explain how I messed up tapping into the wrong injector wire at first and had to tap into the other one to get an RPM signal, so I did figure that out. But again great questions!
Wouldn't it be better to tap into the coil wires for the RPM reading? I guess injector pulse would work too but every tach I've installed got it's reading from the ignition coil.
Yes, I believe either way work probably work. All the write ups I read on Charger forums and RUclips suggest using the injector wire, so that’s the way I did it.
The other forums say it is a green wire to the throttle body to activate the long runner in the intake the whole purpose is to open the long runner in the air intake…
When you plugged up the map sensor to the MSD box, you already had a connection ready for it? Or what exactly was it? I got a 6.4 manifold and am ordering the MSD box and everything else I’ll need. Any help is much appreciated
Okay last question before I get started. Can this run without a tune? I plan on getting my pcm unlocked soon but it maybe a week or 2. So would it be fine without a tune for a short time?
Has anyone ever done this to a ram 1500? I got a 19 5.7 And I’ve found a 6.4 intake for 200 bucks so I plan on picking it up here. Any tips or suggestions?
I have a 06 SRT-8 Chrysler 300, would it be any difference if I remove my bullet proof silver cast iron intakes for the newer black plastic 6.4 intake?
How do i get rid of high rev and car going into sport mode after swapping in the 6.4L manifold? My car check engine light comes on and it says i have an air intake leak
And to be honest, if I still had this car, I’d probably go back to the stock 5.7 manifold. The cost/effort wasn’t worth it for very little results if any.
@@LKfoodstuff I don’t know if you can make more power or not, it’s just that the 6.4 didn’t add much if anything for all the work. If I went back I’d just get the 5.7 intake ported.
I got a question at what point do I get a new transmission. I’m about to put a new performance cam, long tube headers a and I want or put 6.4 manifold also. At what point do you say I need a new trans and rear to handle power
No I didn’t port the manifold. It might be worthwhile if you are making a lot more horsepower than I am to squeeze every little bit out of it, but for a relatively stock 5.7 it’s probably not.
Can I reuse my 5.7 Hemi MAP sensor on the 6.4 Intake manifold as long as long as I have the extension adapter harness? What all needs the extension adapter harness, just the MAP sensor??
A cam would make a huge difference, but this without a real tune has very little gain in my opinion. I still need a revised tune, I’ve just been lazy that’s why I haven’t got it yet lol. The gains are supposed to be torque in the mid range RPM, nothing down low or up top. Some people claim big horsepower gains in the mid range too, but I’m skeptical.
Thanks. You have to tap into one of the injector wires so the MSD box can read the RPMs so it knows when to switch from the long runners to the short runners.
@@goldengam3rxx3 you need it have the active runners inside the 6.4 manifold work. It has nothing to do with the custom tune. You can run the 6.4 intake manifold without it, but there would be no gains over the 5.7 without the runners working.
Yes, mine is an 09, and yes, starting in 09 the 5.7 changed and went to VVT and different heads. You can get adaptors to make it work, but from what I’ve read you lose most of the benefits of the 6.4 intake manifold on a pre-09 because the ports are a different shape and size. You’d be better off with a 6.1 intake manifold, especially if you plan on putting a cam in it later down the road.
Thank you! You may want to reconsider putting the 392 intake manifold on a pre-Eagle 5.7. The ports don’t match up at all so you have to use adapters, which from what I’ve read defeat the benefits of it. The MSD box is used to switch over from the long runners to the short runners at a certain RPM. The Circuit Boss is used to protect the electrical to and from the MSD box. It’s basically like adding a small remote fuse block.
Great video! Can you do me a favor and tell me exactly what wires are connected where? I did my install and wiring but the MSD box isn't getting any power. I tested all connections and they're all good until it gets to the Circuit Boss, after that no power to the MSD box. I've spent like 8 hours just making sure everything is set up properly and as far as I can tell it is...
I wish I could, but I bought mine used so the wiring harness was already together so I just had to do the power, ground, tap to the fuse box and the injector wire. Do you need to know any of those?
I don’t know. I didn’t dyno before or after. I ran my best time at the 1/4 track after installing it, but I also installed better gears so I’m not sure I gained much hp/tq at all. I need to get a better tune though so that is a big factor.
Would you recommend installing the manifold with 6.4 injectors and fuel rails or would you suggest sticking to 5.7? I can get a revise tune with the bigger Injectors but is it worth it?
Great question. I was told there’s no point in using the larger 6.4 injectors because they’d be too much for the 5.7, unless you’re making over 450hp, which I’m definitely not. The tuner would have to scale them back basically to 5.7 specs in order for the engine to run right. The 6.4 fuel rails are identical to the 5.7, as far as I know, so you should be able to use the 6.4 rails if you want.
@@n-power-automotive yeah I still haven't gotten mine wired up. I know each is different I ported mine before I installed it I need a throttle body to compensate for the throttle port I did on it and I need a tune to compensate for my mods. These computers expensive lol
@@aaronferguson47 yeah man I’m lucky since I already had a custom email tune from Hemifever I just emailed him and he sent a revised tune no cost. The wiring was definitely the hardest part of the swap, besides cleaning those intake ports out. That was nasty lol.
@@n-power-automotive yeah I saw it was super rough. With this intake manifold you get more low end tq but now with a wider range to hold the curve longer
@@DanielJohnson-ec8rk vented doesn’t mean there’s zero pressure in the fuel lines. I know this from actual experience taking the fuel rail connector off without taking the gas cap off. Guess that happened? Fuel sprayed out. Second time I took the gas cap off, no spray. So, despite my lack of knowledge, I hope you learned something today:
@@n-power-automotive that’s pressure between the pump and rail. Removing the gas cap has zero effect on that pressure. There is no positive or negative pressure in the tank by design

@@n-power-automotive nah I figured it out, I do have a bad Circuit Boss. Thanks for getting back to me though I really appreciate it!
@@idunno3639 glad you figured it out!
So we’re the injectors the same size on the 6.4 ?
No the 6.4 injectors are bigger.
How much HP and torque did the new intake add to your car ?
I don’t know. I didn’t dyno before or after. I ran my best time at the 1/4 track after installing it, but I also installed better gears so I’m not sure I gained much hp/tq at all. I need to get a better tune though so that is a big factor.
What exhaust are you running?
Do you have any other mods on the car?
Lots. Watch some of my other videos.
Do you have upgrades heads
I’m curious if my 5.7 can be a direct swap for a 6.4 or the 392 SRT engine? Anyone can ride me any information?
i dont think so because the rt engine is 345 while the scat/srt392 are of course 392 cubic inches so youll probably have to get a plate
looks like egr sludge tome.
2009 5.7s don’t have an EGR valve.
@@n-power-automotive i didn't realize that.
Does anyone know if this would work on a 2012 Dodge Charger R/T?
It will yes, works on all 09+ 5.7 hemi’s
Would you recommend installing the manifold with 6.4 injectors and fuel rails or would you suggest sticking to 5.7? I can get a revise tune with the bigger Injectors but is it worth it?
Great question. I was told there’s no point in using the larger 6.4 injectors because they’d be too much for the 5.7, unless you’re making over 450hp, which I’m definitely not. The tuner would have to scale them back basically to 5.7 specs in order for the engine to run right. The 6.4 fuel rails are identical to the 5.7, as far as I know, so you should be able to use the 6.4 rails if you want.
@@n-power-automotive ok cool. Thank you for the reply. Im looking to do this mod next week
@@agametheofficial37 cool good luck!
where can i get the 6.4 i take manifold? i also have a 2009 5.7L challenger
I found mine in a Facebook Charger group. You could probably also find one at a junk yard.
Is it the brown wire on injector 8? For rpm reading?
Yes, the brown wire with a blue stripe on 8.
@@n-power-automotive yeah I still haven't gotten mine wired up. I know each is different I ported mine before I installed it I need a throttle body to compensate for the throttle port I did on it and I need a tune to compensate for my mods. These computers expensive lol
@@aaronferguson47 yeah man I’m lucky since I already had a custom email tune from Hemifever I just emailed him and he sent a revised tune no cost. The wiring was definitely the hardest part of the swap, besides cleaning those intake ports out. That was nasty lol.
@@n-power-automotive yeah I saw it was super rough. With this intake manifold you get more low end tq but now with a wider range to hold the curve longer
@@aaronferguson47 that’s what it’s supposed to do. No real horsepower gain, just torque in the low to mid-range power band.
U said nothing about which vacuum spigot u used the 6.4l has 2 do u use both plug one ??????
where did you find the manifold at?
Would I be able to do this on a 05 hemi 5.7
You could with adapter plates but it would only be for looks. It doesn’t add anything for pre-09 HEMIs.
What rpm do you have your msd box set on?
Oof it’s been a while since I don’t own the Charger anymore, but I think it was 4,800 RPM IIRC.
One question, what did you do with the intake manifold? I need one 😂
You mean the 5.7 intake manifold? If so I still have it.
@@n-power-automotive would you sell it?
@@nickking2075 sure. I don’t have any need for it anymore. You can email me at highway65design@yahoo.com and we can go from there.
@@nickking2075 I have one as well
@@YachtLife I need one for a 2012 Dodge Challenger
lot of jobs
Removing gas cap doesn’t relieve any pressure. This is someone with zero knowledge
😂 ok you leave the gas cap on and let me know how it goes.
@@n-power-automotive I’ll do it knowing that the gas cap is vented
Because I have wisdom and experience you are lacking
@@DanielJohnson-ec8rk vented doesn’t mean there’s zero pressure in the fuel lines. I know this from actual experience taking the fuel rail connector off without taking the gas cap off. Guess that happened? Fuel sprayed out. Second time I took the gas cap off, no spray. So, despite my lack of knowledge, I hope you learned something today:
@@n-power-automotive that’s pressure between the pump and rail. Removing the gas cap has zero effect on that pressure. There is no positive or negative pressure in the tank by design
way too much rambling, get to the point.
Thanks for watching!
Where did you get the caps for your fluids ?
I bought them second hand but a company called Billet Technology makes them.
