Edelbrock Cross Ram
I think that's just cosmetic. Think about it, each runner has airflow moving in opposite directions to the one next to it, if they had crossovers, the turbulence would be unreal.
As one of the other posters above said. Ummm how are we going to add oil? 
This is pretty sweet. I might have to end up selling my ported ls3 intake to help buy this if it pans out and adds a few more ponies.

I think adding oil will be a little more challenging, but not impossible. Look at the manifold where it hangs over the valve cover, it looks like you could angle a funnel in there and make it work.

A crossover between 2 plenums is actually a good thing for balance. This info came from a Gm engineer, which advised me on the cross ram dual plenum I've worked on here & there & never completed.
The photos I posted show the oil cap is uncovered and completely accessible as normal.
I like how he was surprised that the twin turbo guy planned to make over 1000hp... that's almost the norm these days when it comes to forced induction.
The question is going to be, will it fit in an f-body....

Heck, I asked one engineer for a part number for a product one time and he didn't even have a clue what item fit in what engine.

Verdad Gallardo I visit a lot of companies that make many of the parts you build your motors with and can say that most of the people working there and designing the parts have no clue about their use. I mean they know what a crank is for,but they are clueless beyond that. All they do is design the parts and send them to manufacturing.

When they say they fitted the intake to a test engine and they blew it up...you really have to wonder what or how the hell they were testing !
Sounds like they just bolted it on and hoped for the best whilst monitoring nothing ! lol
Makes me extremely nervous when a company admits that they toasted a motor early on basically from their own mistake.
You would think they would have put it on a test setup with O2's in each cylinder to see how the airflow was biased for each cylinder, and would have taken small steps to get the AFR right before just blowing it up.
At least that's how I tuned my setup. Small rpm increases and monitored the afr. Made sure I wasn't going to go critically lean before stepping up the rpms and pulls.... oh well.
Buyer beware... this **** might blow your stuff up.
It is funny that he admitted that but who the hell knows what really happened. It could have been as simple as forgetting to swap fuel before the first run. We are all just human, aren't we? It will probably run similar to every other intake out there ie big cubes and big RPM to take advantage of it.

Exactly! Too funny. To your point, they probably put it on, didn't have any clue about tuning it, and just gave it a full blast run and it detonated from leaning out and took out the ring lands.

But same applies to any aftermarket parts. Many will get away with just bolting in on and driving away, but everyone knows that carries some risks.
Still doesnt take away from the fact it does look like a great piece. Whether they'll ever get the price down to where it will sell in decent numbers, is another matter.
IMO if it's over say $1500, I just cant see people buying it, unless it really does produce spectacular improvements over everything else out there
It's in the nature of engineering to test and fail before coming closer to perfection. Guarantee that the error resulted in a better final design and the issue won't ever happen again. Kind of like the wing-to-body join on the Boeing 787. Designed, built, tested, found a major error (like, wings-fall-off, everyone dies level error), design changed, airplane refitted and tested, final design better than it ever would have been without first ******* it up.

Customers would have a lot of **** blown up through incompetence.
Any imbalance should have been picked up in milliseconds whilst testing on the dyno....not after it blew **** up. That just shouts amateur.
Not really a reflection on the product, more whoever they had do the testing.....who clearly shouldnt be testing !

Given the number of responses in this discussion, I would imagine that a good lot of people got mildly moist when they heard about edelbrock making a cool new intake. That's because edelbrock hasn't earned its reputation by putting out **** products.
If this was a no-name Chinese intake, this discussion wouldn't have made it past the first page.
Edelbrock has probably blown up hundreds of motors testing their products. Better them than us.
By the time this intake is out, I seriously doubt that you have to worry about it blowing up your engine.
Even if this intake doesn't have a balancing tube between the plenums, you can always run an X-pipe in your cold side plumbing, or run a dual inlet, single outlet intercooler and split the intake charge with a Y-pipe after the intercooler.

Oil fill looks easily accessible. Four balance tubes linking the banks. Interesting that they broke ring lands with detonation during early prototypes:

I'm going to wait and see what they decide to do with a single throttle body setup. Twin is nice if you have either twin turbos, or a big ci NA motor, but with a single procharger, all I need is one throttle body.

I'd be interested to see the insides of their cast product on smoothness & if it has a good raised air horn design. I'm sure like any cast product, there's room for someone with porting skills to make improvement.
The basic construction [ and color] looks like something from Ferrari, which I'm sure was among the first to have a cross ram dual plenum design.
I first logged on to this thread wondering if it was a misprint, but I guess someone at elderlybrock has been tracking our thread activity here & saw the need.
