Gen 3 Hemi dual plane.

My question was just a clarification on the dyno curve. I wanted to make sure i was reading and understanding it correctly. Appears from approx 4100-5400 the OEM plastic intake and TB are actually higher (a car 08 and older 5.7 manifold?). Not saying thats good or bad, just clarifying.
obviously anyone winding higher than 5400 could benefit, but 4-5k also alot of street guys "seat of the pants" wheelhouse... so again just asking/clarifying. I'm not touching on the carb vs efi argument, especially since this gentleman was wise enough to design his intake with both versions avail.

please confirm or refute my above comments, and thank you in advance! congrats on the kit!
 
Yes, the stock intake numbers were a bit higher than the numbers for my intake. There are a few things that I am working on to retest. The intakes I used is are bone stock. The advantage the stock intake has is the runners are very long compared to my runners. There is also another advantage that is has as well. I am including a pic of the view at the divider from the throttle bore. On a single bore throttle body I'm sure there is an issue with turbulence over the center divider that won't be an issue with a 4bbl throttle body. Again, that's where the issues end. When I test the reworked center divider I may update my machining program or create an option for a single bore throttle body. Something you won't see on the dyno is improved throttle response from the smaller plenum. I also have 1415miles on the intake in the Chrysler now and loaded with baggage and a trunk full of tools and supplies to fix a friends truck out in Illinois we had 23.5mpg.

I finally found some time to install the manifold and I can say I'm very pleased with the result although I haven't done any road testing other than warming it up and checking the idle and revving it up some. The idle is solid and the engine is very crisp. This is running on a 03 PCM and has a lot of cam, so there has been a lot of tuning done on it. I'll start the SC install tomorrow and will start testing/tuning after that.

 
Insulated braided hose clamps It appears....bbk uses hardware store conduit hold downs....not a fan of either for that job....
 
If I'm building a high power engine, eventually with a procharger, would I see better results with yours or one of the other single carb intakes also throw in I will have the one I use also ported
 
Thank you for the real life experience and photos. I just figured that one of the others possibly may be better for a FI car being single plane
 
I have no experience with the other manifolds, but I can say I have excellent drivability and transition into boost is smooth. I believe the manifold has excellent low end torque. My engine has a pretty good cam and BV heads and idles better than it did with the OEM manifold. This is using a 03 PCM which has limited tuning. I'm impressed.
 
I got mine from Jegs but they look the same. Keep in mind my rails are Modern Muscle fuel rails and are 3/4" in diameter. I would measure your rails and confirm their diameter before ordering.
 
it was originally posted that the carb version would be released first. that however does not seem to be the case. so the question is are they ever going to be released? it has been several months now.
 
I sent you a pm on Monday or Tuesday w2 stroker. The machine shop I am using is the issue. I am in the process of fixing that now. I have carb intakes available.

w2 stroker, you are in luck! The three manifolds I know about were shipped out quickly. You should have yours on by the weekend. Make sure to post pictures... :cheers:
 
joey I just saw your pm and sent you a reply. I will definitely take one. currently in the middle of painting under carriage and engine bay right at the moment.
 
Just to clarify. I am working first come first serve. I received 4 intakes. You were one of the first ones that wanted one w2 stroker, the other 3 are already sold.
 
appreciate you holding one for me :) this will be a huge help to me. just came in to get a beer now its back out to the garage

hemijoejr,

According to the discussion on the Pace crate motor thread, http://www.forabodiesonly.com/mopar/showthread.php?t=340726&page=2, they say that your intake is more suited for the early 5.7 hemi. Will you be making another version for the larger Eagle/6.1 ports?
Thanks!
Wailin

To clarify a note-worthy point. Our eagle makes 100 hp more than Stock, and spins to 6400 rpm...at that level ours needs a single plane.
I can't speak for a stock eagle, or anyone else's builds.
Engine flow 101 is as simple as we outran the abilities of any dual plane, low rise intake.
Joe's intake. Looks great, and has an old school vibe.
I dont want our 470 horse engine that we spun up to 6400 rpm, preferring a single plane intake, to be spun around as anything negative toward Joe's.

Again we thank joe for letting us test it, and I cant say enough about how nice the fit and finish was.

As Joe posted in post #77, he is working on some modifications to see if it improves the performance. Also may have some casting changes to work better with a single blade throttle body. But, like I said in the other thread, It's looking to be the best choice, performance wise, for an aftermarket intake compared to what is currently available.
 
Thank You John and I do appreciate the kind words everybody!! Keep in mind everybody that that everything is a combination of advantages and disadvantages. All intake manifolds are no different. A manifold that is designed for one purpose always will excel in that aria. The factory plastic Eagle EFI intake is an excellent piece but try to put a carb on it. Try to use one with a truck accessory cover. There is more than just a design that makes an intake manifold, it has alot to do with drivability, application, and package. Due to the 14-15" length of a tuned runner and the EFI there are a lot of advantages due to sonic supercharging and the fact that the EFI is force feeding the correct amount of fuel directly into the cylinders. Now take the same intake and adapt it for a carburetor. Now you have an excellent EFI intake but a horrible carbureted intake that has poor fuel distribution, puddling issues, and horrible throttle response due to the gigantic plenum. In general it would be a nightmare!! When I started this intake project I had to take in consideration a lot of things. Drivability (very hard to measure) Application, Carb 4150 is a standard, EFI Must be compatible with multiple EFI systems and the runners need to be the same volume and length to eliminate fuel distribution issues. Height, Cant be too tall. Downdraft due to dual purpose Carb or EFI. The runner volume cant be too large or too small. The best we could do is 7" for runner length and it had to be in a dual plane configuration in order to get that number and keep the height down. I am constantly learning and performing tests. I am not independently wealthy. I have recently purchased a car solely for the purpose of R&D, use my own show car, and even beat up my family members cars for more development. I already have more stuff in the works and take all info that is given to me or that I paid for to further my projects. Right now there is nothing in the works for a larger runner dual plane. Not saying there wont be though. I have thought about it. I do have my intakes port matched for the Early 5.7L and Eagle/6.1L heads. So far I can say this, The throttle response is crisp with a carburetor netting me the best 60" time I have ever had even over my $3750 Hogan sheet metal dual quad cross ram. (Large plenum VS Small plenum) I have run a 120.1mph quarter with a single 850 Holley and no carb spacer, almost equaling my PB with the cross ram at 120.9mph with dual quads (1300cfm combined). I forgot to mention that I shift the Cuda at 7500rpm and cross the line in excess of 7000rpm with the intake out of it's sweet spot and yes I have chassis dyno results that show that it hardly drops off at all and would continue to pull if I let it. On a bone stock factory EFI early 5.7L with no hand work coming close to equaling the HP and torque curve of a long runner plastic intake and getting 23.5 MPG in a 2005 300c. Is all of the testing so far on the early 5.7L, yes because that is all that I have had access to currently. Dave at Modern Muscle is currently fully porting one for a big cube truck engine and I will be racing one in the Duster and my Barracuda so there will be more to come.
