In the effort to continue the quest to go as fast as possible on bolt on's, I purchased the new Edelbrock manifold.

This thread will be dedicated to the results I see and also comments about the design,etc.

I will go with this combo:

Edelbrock Manifold and fuel rails - $989
OEM 92mm Throttle Body - $250 w/ bolts,etc
BWoody Short Ram CAI - $364 w/ custom powdercoat job

This isn't a cheap mod for sure. All told, the parts above are about $1,600. I will hopefully be able to sell my current setup for about $700. So, I'll be in it for $900.

I saw a dyno from OST where a 6.1L manifold gained over 20 rwhp on a stroker over a ported 6.4L manifold. Granted most of the gains were up top, but I hope the Edelbrock manifold provides better low end support.

I would consider it worth it if I could gain 15-20 rwhp for $900.

Anyone else that installs the manifold is welcome to post their results and thoughts here.

It's awesome to be able to live vicariously through you...lol

Seriously, I love what you do and the information you report. Thank you

Having mine off already once, I can tell you that it is an easy job. You can probably have the manifold off the car in under 30 minutes.

I will also report all the torque specs for the manifold and throttle body. I hope Edelbrock provides this information with the manifold.

My tune is spot on right on... kinda funny I made 40 revisions to get it 99% perfect and now it is going to change...

However, that will be one of the first indicators of additional power. If my tune leans out some, that is a good sign were getting more air. I'll also be keeping a close eye on my aircharge numbers. They currently peak around 910 m.g. or so in the warm weather and approx. 945 m.g. or so in cold weather.

I hope to see them bump up 30-50 m.g.

According to several good calculators, even a 25 rwhp gain at my 1/4 mile speed will only net me around 1.8 tenths. So, if I get asomething around 15 rwhp, I'm probably only looking at a tenth... maybe a little more.

I've got to temper my expectations to some degree. However, if I thought I was going to be 11.3 - 11.4 without the manifold.... MAYBE just maybe I can see an 11.29 in negative DA.

Some may scoff, but Michael Fissel went 11.38 in +500 D.A. w/ only long tubes. If the manifold nets a tenth and I'm at -200 or 300 D.A, then I think it's possible.

My 11.68 run was at +1,200 D.A and also prior to my retune. Full TM was on and my fueling was screwed up.

Lets bench race...

11.68 @ +1,200 DA (Proven)
11.53 @ +1,200 DA w/ retune (No TM, AFR @ around 12.3, shift points, etc.)
11.39 @ -200 DA (About a tenth for every 700 ft. reduction)
11.29 @ -200 DA w/ new manifold and TB combo.

:)

Nice, glad you are sharing this information with the rest of us, as it's always great to get real world data and not have to rely on just the vendors information. I'm looking forward to following the thread and seeing your results. :thumbsup:

Very interested in the results. I have been waiting for these to become available and to read some write-ups on them.

This will be interesting to compare to vendors predictions.

Got a message from Edelbrock today that they supply bolts for the throttle body. They also appear to supply a metal type gasket.

This is good because the OEM Hellcat TB bolts are $17 each and the gasket is $30.

I snagged a brand new Hellcat TB off Ebay today for $199 shipped.

The manifold and throttle body should arrive next week, so hopefully I'll have them installed next weekend. I'm not sure when the CAI will arrive since it is being custom powdercoated.

Here is a picture of one installed. I must say that it looks nice.

I'm following this thread, as I've been trying to dig up real world independent numbers on this product for months now. I called Edel Brok over the weekend and found out that they finally released the manifold for production. I'm hoping you get your's soon, so we can get independent verification of the numbers. Where did you find a picture of the Manifold installed. Thanks for posting all of these details.

New Hellcat TB arrived. Nice looking unit. If you go with this manifold, it would absolutely be my recommendation. No reason to pay big $$$ for a ported unit.

I snagged mine off Ebay for $199 shipped.

Well still waiting on the manifold to arrive. However, the new CAI arrived and I pulled the stock manifold.

The 92mm Hellcat TB is a perfect fit in the BWoody coupler. As expected, the new throttle body is also a direct connect to the factory harness.

I did order a 18" IAT sensor harness extension from LMI to make sure I had enough length to relocate the IAT into the coupler.

The CAI is powder coated in prismatic black and is similar to the phantom black paint on my car.

Although I've done it before, pulling the factory manifold takes less than 30 minutes. The hardest part is getting the vacuum line off the back of the intake manifold. It came off easy this time... the first time not so much... I actually cut the line since you have plenty of length.

My head ports had a fair amount of oil in them. I've seen this with two catch cans.... the BT and Bob's.

The cans help, but they certainly still let oil vapor into the intake and the combustion chamber.

I went ahead and tweaked my tune a little with some more fuel. I will have to see what codes are set (if any) with the active runner disconnected. HP Tuners has a toggle in the software for the active runner; however I have heard it doesn't work.

No different than installing a PD blower though, so I'll just shut any codes off.

I've got to check on whether a throttle body harness extension is provided by Edelbrock. It wouldn't be required for a 5.7L, but it certainly appears that the factory harness isn't long enough on the 6.4L to reach the new throttle body location.

Now, in the event they don't provide one... I will just cut the factory harness and solder in an extension. I need to use my Class 3 solder cert from time to time anyway.

I should know something about that tomorrow. If I have to cut it, I can work on that until the manifold arrives.

I spoke with Edelbrock and they said the 6.4L throttle body harness should work fine. The guy had the installation procedure in front of him and didn't see anything about an extension harness or having to extend the harness.

For some good news, my manifold shipped today and I should receive it Thursday. I'm off work after tomorrow, so I should be able to get it installed by the weekend and do some initially tuning / testing.
