BEST 5.7L Intake Manifold Dyno Tested...

6.4L 392 Intake Manifold for 5.7L hemi engine Does it add any HP/Torque? Watch this video about the 392 intake manifold on 5.7 345 Hemi before deciding to buy a new intake manifold. Some say go with 6.1L Hemi Manifold or Edelbrock Manifold which is based off the 6.1 Intake Manifold. Before looking into any other manifold for your charger RT or Challenger RT 5.7L hemi v8 make sure you watch this! This will show what the 392 6.4L Intake manifold can do to help your HP & Torque. The active runners in this intake manifold really do work great.

[@BurnseysRT]

Great video gents. Awesome feature on your channel and so cool to actually prove out the gains over the whole power band. This is way better than having no gains over the power ban and a peak in power. This kind of increase over the ban will be felt at all times and on your every day driving. Way better than just a peak of 15-20 HP. Nice work Build It!!

The best intake manifold is an aftermarket manifold and u don’t even gotta touch it until u port cam headers etc etc otherwise it’s a waste of money .

Putting a 5.7 ported manifold is good enough , you need to get ported heads.

[@t.t.6398]

Midrange gains aren't near the same. Tacamo01 and several others including myself are seeing gains of up to 30hp and 60tq in the midrange. Low and midrange gains are what this mod is for where you spend 90% of your time driving. Peak gains are nice but you don't run your car at 6000rpm all day so you hardle ever see them. Why bother to do a mod that will be used les then 10% of the time?

[@repoguy1]

Hey @RTLife Im going back through some of your old videos, and I'm getting ready to do the intake on my 5.7. Should I go with a 6.4 intake or should I go with one of the Holley intakes for the Edelbrock. And then my next question is. Can you Bolt the 6.4 intake on without a tune or do you absolutely have to tune as soon as you install it

Need a good detail parts list and more install instructions... ex. setting the add on control box for valve set up? and do we keep reg plugs and injectors? Will it run stock without tuner and pcm upgrade? I know you say “ bolt on” but it would seem injectors and spark would need attention? I love the posts, makes it very tempting lol detail instructions will make it happen!

[@RTLife]

I know he went with Long tubes - not sure what he did after that. I believe it's straight piped but not 100% sure

[@gl3618]

This should make sense to anyone who knows a little about basic engine performance. Motors, especially hemis, love to breath, both in and out. Increase the efficiency in their breathing cycles and you will see more power. The reason max HP isn't really increased is because nothing has been done to give the 5.7 more room for the power, just more efficiency and access to air sooner in the RPM range. It is less restricted by the amount of air it gets right off the bat. To get more power all together you'd need to tell it what to do and how to find room for more power (turbo, cam, tune, fuel system, injectors...). You still end up with the stock programming for fuel/air mixture so your max HP doesn't move much, but you access more air quicker, letting that beast suck in beautiful air. Guys who expect huge gains from just an intake crack me up. Same throttle body and intake manifold mean minimal gain because all that excess air now coming in gets underutilized by the stock TB and manifold. Some gains are seen, yes, but its still restricted. I love my 16 ram 5.7. It surprised a challenger and camaro trying to run a 45 roll the other day. Caught and passed both of them in a quad cab 4x4 with 34s. Lol. Confuses the hell outta stock "muscle car" drivers. Did get my ass whooped by a sleeper lightening before though....lol

[@gl3618]

I should specify i was talking about an air intake, not an intake manifold, when talking about people expecting huge gains from one bolt on. If you get huge gains from an air intake, your old intake filter must have been trashed. Haha

[@tiansummers2110]

OK so my 14 challenger has a corsa cai kooks longtubes and 3" slp loudmouth catback. Looking to add a ported 392 intake manifold and a ported 87mm throttle body next... Last step will be a cam but before adding the cam will I see gains from the intake an tb coupled with what I already have after I retune... Or only throttle resp once until I get them cam

[@jhenry248]

What about fuel volume (not pressure)? Do the 345 and 392 have the same fuel systems? Do you swap out injectors also. The reason I'm asking way back in the day before Fuel Injection we had 4bbl , dual quads or 6 packs. When you upgraded intake air flow we re-jetted the carbs and installed high volume fuel pumps along with timing mods to optimized the increase fuel and air flow. I know you can optimized the engine timing with a Diablo but can you increase the amount of fuel or the duration of the nozzle of the injectors?

[@RTLife]

The air/fuel ratio likely has to be adjusted after this install - he chose to keep the 5.7 injectors, I chose to put the 392. He is going to get this tuned properly so he maximizes the gains & makes sure the engine is running properly with this new setup. This just proves though the manifold is in fact helping performance even without a tune

I remember researching it a couple of years back - I have to check the dyno gains again

I heard it does work - but you will need something extra. Not sure what though
