360 magnum intake porting

porting the kegger intake manfold for my 99 dakota rt with a 360 magnum.
picked up 15 horsepower at peak and over 15 horsepower in the midrange and picked up almost 20 ft/lbs of torque across the midrange

[@blownaway4371]

Like the video. I usually use Ultra gray and basically glue the intake gaskets to the intake to keep it in place. And cooking spray on tbe head side to help it not to stick. (But, never really had to go back in)

[@jeremymardlin5381]

The one I just played with was a metal pan gasket. 98 still has the divider.

[@thomasbeyer]

Must be pot luck on the divider. The last two 97 intakes I played with had no divider

[@MrThomasfouraker]

Definitely alot of work but shows some real potential in the kegger manifold. Appreciate the time and effort to put the content out there for these old magnums. I think the tubes turned out superior than what the VRPs would have.

[@thomasbeyer]

Thank you

[@bryancarey8166]

Hey any chance you will be will to sell one that you have already done all the port work too?

[@svr27rr87]

Mawawawawahahaha!!!! Hell fkin yea Lite it up brother!!!!!!!

[@jlsracing997]

I looked and didn't see what you found with the wedge in the bottom of the manifold. Did you install and dyno it?

[@thomasbeyer]

It was a small part of one of my Dyno videos but it didn't make any power I believe it actually hurt the top end by a couple hp

[@jlsracing997]

@@thomasbeyer You remember if it was the short or tall one or was that even a choice when you bought it? Did you notice any thing with it?

[@Joe-jd4pn]

Is aloominum like aluminum?

[@wiredspeaker5658]

Nothing like a good reason to grind for hours on end. I find it therapeutic anyway. Definitely going to go this route. Thanks

[@thomasbeyer]

Thank you. Get yourself a good scented candle and go to town on it lol.

[@jamesstrickland4019]

What would it cost to have this done

[@thomasbeyer]

I'd contact utawesome performance.

[@docfischer7291]

It’s a lot of work but with the volume reduction plates the perform just as well or if not better than the crappy air gaps out there UTAwesome on here has a great coverage of it .

[@thomasbeyer]

Have you checked out the before and after Dyno video? IV got another coming soon-ish I hope of my air gap testing. air gap did pick up at the higher rpms but only 10hp or so nothing as extreme as people claim. At least with my current setup. Bigger cam coming soon.

[@docfischer7291]

@@thomasbeyer I haven’t. I just started searching around again for my current project. I have seen the potential though. I think the 318 I am doing for my sons car will have 11” runners. Seems to be the happiest with hp to tq equalization

[@ottoscorzeni630]

такой впуск будет работать только на высоких оборотах, низких не будет (то есть тяги на низах нормальной не будет)

[@toasteroverdrive1097]

I can't understand why that intake is shaped like that. It's shaped like for an engine that could rev to 12000 Rpms. Takes up a lot of valuable real estate. I would have liked to find an intake with a dual "H" pattern like the old engines. Also would have liked to find an aftermarket Throttle body shaped with dual small primaries and bigger secondaries like old carbs.

[@thomasbeyer]

The intake is shaped like that to have really long runners for low rpm torque and it definitely does that but a dual plane intake is definitely a better option. Iv had the same thought on a staggered bore throttle body they make staged throttle bodies but I think it would be beneficial to have small primaries for gentle throttle response if that's what you want and then the secondaries can be as big as you want for all the flow.

[@georgesantiago6005]

Use some exposy mix with the metal grinded.

[@randelcaudle7435]

best thing for keager manifold is scrap pile get the hughes engine air gap manifold never look back.

[@thomasbeyer]

Iv had both. Wit the the smaller cam the Hughes made no difference over my ported manifold even at 6200rpm. So in my opinion it really depends on what you have. With the new bigger cam I'm sure it is making a significant difference.

[@TurboRanger351]

Holy crap! That's a ton of aluminum

[@thomasbeyer]

Lots and lots of grinding

[@cegadventures2492]

Will you be getting new headers soon, if thats whats holding it back.

[@thomasbeyer]

Yes it's in the works right now

[@Mr.D83]

I have a 360 first gen durango and ive been wanting to completely gut out the kegger and remove the runners completely to where it just feeds right in to the heads.

[@thomasbeyer]

I wouldn't do it. It will kill a lot of low end power and I don't know that it will make it up on the top end. Early lt1 intakes have very short runners and they do pretty decent tho.

[@thatbuelldude189]

Would doing the same thing to a v6 be worth anything? Already running a stock v8 tb Will be running long tubes and a dual exhaust with a xpipe

[@thomasbeyer]

Absolutely yes

[@LawrenceOrsini]

Can you post the graphs from the dyno runs? I’m curious to see how much bottom end you gave up, if any.

[@thomasbeyer]

I can after I have them sent to me. It didn't lose anywhere thus far all gain

[@LawrenceOrsini]

@@thomasbeyer 15hp for ~12 hours of work isn’t bad!

[@thomasbeyer]

Well worth it after seeing the results. Working on 1.75 long tubes now

[@TheKnifed]

That grinder is on clearance, discontinued. Just a FYI

[@stickfightjesser]

Almost exactly what I did to mine, except I used a speed limit sign as volume reducing plates, have not used a wedge either but I did think about going back in later with one I just don't really have the ambition to dyno mine so thanks for the grunt work haha. I'm wondering now if cutting the throttle area in to a large oval would be worth it next time I remove to do the wedge...then maybe get one of them fancy expensive throttle bodies.. Great content as always

[@thomasbeyer]

Thank you. At higher RPMs mine is starting to gain vacuum so there's a sign that it needs a bigger throttle body but I'm not going to do that till after I get my headers done and see what 1.75 long tubes are worth

[@stickfightjesser]

@@thomasbeyer Man I'd love a set of headers but the ZJ headers are notoriously expensive and I haven't got around to getting a set of dakota headers modded up yet. I did just pick up a 95 Dakota with a 3.9 im thinking of dropping in the 5.2 i pulled when i 5.9 swapped my ZJ.

[@thomasbeyer]

Hell yeah why not. I'm working on a set of long tubes I think will be a fairly cheap option considering nobody makes long tubes for Dakota's anymore and when they did they were a 1300-1400

[@svr27rr87]

@@thomasbeyer check out what JBA performance has to offer.. the jba shorter headers im running on my 2000 RT 5.9 v8.. are so worth it..

[@tomb374]

great work. while I was watching i was sometimes thinking I don' think I would do this or that but your final results proved me to be a little unadventurous... (ok say it...skeered). So thank you very much for your time and effort and posting this video... by the way. are you able to keep the check engine light out? good question for folks who have to pass emission tests...

[@thomasbeyer]

I have to pass emissions where I'm at and the porting didn't hurt that part at all.

[@thomasbeyer]

The Dyno results were on top of an already modified manifold. I thought it was more stock when I posted the original Dyno video. But when I opened it up and had it next to a stock one I could see the difference lol.

[@TheProchargedmopar]

I shared this to @richardholdener as he was interested in this info. Hey, with 15psi boost thats 40tq and 30hp extra above the modified manifold you had on there.

[@thomasbeyer]

I appreciate that. I enjoy Richard holdeners videos very interested to see how far he takes it as I'm building mine. Working on a set of 1.75 long tube headers right now hopefully will be ready for this Saturday.

[@TheProchargedmopar]

@@thomasbeyer I've had a billet wheel 78/75, SEP1000's, and a microquirt on the shelf for 3 yrs. Needless to say I'm making almost NO progress. Got caught up on a 318 build for my son's car and it too fizzled. Good to see you are on the ball. Excellent vid!!!!

Thank you. What car are you planning on running that in? Microsquirt is the way to go very easy and fast tuning.

All my keggers went to scrap metal ...... install dual plane .......

[@thomasbeyer]

Already did. It really didn't pick up much from my fully ported kegger. But it beats the hell out of all the grinding and welding.

[@Ratridez]

@@thomasbeyer I've even had the thought of milling out the 2 barrel and welding in a 4 barrel carburetor style flange .

Very nice work thank you for your video need it thank you

[@CarlosLopez-tt5py]

Great video, help to understand the concept of more air circulation to increase hp/torque. I m going to do the same for my 3.9l dakota I need more torque .thank you for your video and your detailed info 👍

[@thomasbeyer]

Thank you

[@markpollard500]

I've done quite a bit of modifying to my intake and throttle body.. feels like I got some gains. But now seems like the motor didnt like it and wants different timing. Developed a pre ignition-detonation knock after awhile. Has this happen to anyone else?

[@thomasbeyer]

I've never had that problem on any of the trucks I've played with personally. Does your engine have a good bit of blow by or lots of oil in the intake?

[@markpollard500]

I have an oil catch can vented to atmosphere..

[@markpollard500]

Have you heard of plenum divider air gaps? I did this also..

[@markpollard500]

It's on top of intake under throttle body..

[@thomasbeyer]

@@markpollard500 maybe but I'm not exactly sure what you're talking about. My Dakota's tuned so I don't know if it could be a tuning issue but my '97 ram I ported it and did all the things never tuned it and it did pretty good. now it was a fairly lean at the lower end so I put some 24 lb injectors in cuz this was 10 years ago well before I started tuning and that made it run way better.
