New intake going on
I think that elbow is going to cause some big problems.
1) That is a tight small bend. That is going to be restriction no question about it.
2) The divider thing looks questionable at best. It might be good for NA applications, but as Phil said it is going to cause some serious fueling issues.
Personally I would rethink it.

does yours fit under the cowl silver. Cause I have the exact same thing and It still does not fit under the cowl. I have solid motor mounts though. They really do raise the engine higher apperantly.

Whats the difference between your elbow and this one?

Word of advise -cut the diverter out and port the hell out of the inside.
I tested the low profile on a NA 408ci .Comparing that to an Intake Elbow 90 it lost 80hp and almost 100 ft/lbs of torque.I still can't believe it lost that much.Tested it twice to make sure. Edelbrok rates them at 300hp which I believe now.
The FI should be better till higher boost is used.

I do plan on porting it as well as the intake itself once I move back home in a month.
I like doing port work. Its like a wrk of art.
seriously, need to hear more insight about this. I am not just going to cut out the divider. What I was told was that was there to help divide the air evenly. I guess I could just buy another one since they are only 100 bucks and test them out. I am more worried about lean conditions though.
Sevenseries:
Do a search on edelbrock. There is a edelbrock contact that checks this board out. I remember him posting in the long-*** thread on external engine stuff on the new intake they are coming out with. I would love to have him step in here and explain a little bit. I'm sure he has some bona-fide R&D to support their elbows. Maybe i can find his SN.....

I think these look really cool anyway. would this be any good for a stock cube nitrous motor? i have ls1 heads still btw. i hav the SS hood too, will the shorter elbow fit under the SS hood? What are the performance gains from this intake? Would this be a better alternative choice to the LS6 intake? I have been thinking of a new intake to punch me up over 500hp, but i like this because its different and could also make the power.

The divider is in the elbow to appropriate the air in the plenum. These were engineered using computational fluid dynamics to look at airflow distribution. Air will follow the path of least resistance and without the divider the air will push to the back of the elbow and back of the intake.
Is it restrictive? Sure, kind of. This elbow will flow less air than the taller versions; we engineered it to flow as much air as possible while providing hood clearance - flow is 860cfm @ 20.5" h2o . Our taller versions flow more air; #3848 (950 cfm) and 3849 (1,050 cfm) with a 90mm throttle body.
Ultimately if you are pressurizing the intake manifold, your air distribution shouldn't be an issue. And again, the divider actually helps the airflow and distribution.
If you can get away with a taller version (hood change) than you will be able to flow more air and make more power with the mid or tall versions.

Jason, Thank you, thank you, thank you for coming into this thread.... Now if we are pushing large amounts of boost through this intake do we need to worry about lean factors in any of the cylinder range. I do not know about the other guy but I am running a 90mm TB. I am also wanting to push around 19psi with twin 76's. If I need to make other changes I will But I really did not want to change my hood.

Agreed,
I am planning on about 16-17psi through a single S480 with your intake and elbow(I think the mid size that flows 950cfm). I am also using the new edelbrock TB which FWIW is considerably larger than the PTM 90 i used to have if anyone was interested.

I cannot answer that question with any difinitive data. At 19 psi, when you go into boost that intake should be pressurized and pushing air through all runners.
The links below are actual cfd images of one of our new elbows with and without a divider; the difference is very clear.
