Has this been on the market vary long? Is anyone using one of these?
I think it may keep inlet air cooler.

For Chevrolet LT1 and LT4 V8 (1992-1997)
PERFORMER RPM AIR-GAP™ (1500-6500 rpm)
Utilizing the proven short runner tunnel-ram style, both of these manifolds provide the next step up in performance for LT1 and LT4 owners. These are both direct stock replacements for OEM equipment with all required emissions features. Our patented Air-Gap™ design delivers a cooler and denser air stream for maximum power output. These intake manifolds are designed to work with either our #3809-52mm or #3810-58mm throttle bodies. They also accept early and late OEM LT1 throttle bodies and fuel rails. #7107 and 7109 are designed to match #61909 and #61919 LT1 cylinder heads, but will also work with OEM LT1 and LT4 heads with minor head port matching.

$464 for the LT4 at Summit, est ship date 12-7-06, nothing yet on the Lt1 version as they are just now comming out.

 

Sounds like a carb intake. Any pics?

 

i will believe it when edelbrock releases it and someone actually runs the damn thing

 

Well believe it...

Can't believe it's a real LT1 intake air-gapped! I want one now! NOW NOW NOW lol

 

96capricemanager is gonna flame you so bad.

 

we all know they made one. Now the question is who (nO ONE) has one. What gains are there to be made? A whopping .1 at the most.. This has been pissed over before.

 

I'll be honest. If they dyno this thing and it shows some gains, I'll consider buying it. But I will at least want to see some dyno charts first.

 

dhdenney , Dwayne I think is in a good mood. He just ran a 11.953 at 113.07mph the other day, in his little heads/cam tree fiddy

 

Well be what it may, it does offer one thing, a cheapER, note the "er", to a highly inflated value of the GM LT4 intake manifolds, since they are going on ebay for close to a grand, around 500 for the edelbrock wouldnt be so bad. But its like everyone says, If it ever comes out, its been scheduled for release for quite a while now.

 

good lord thats alot of money.

 

edelbrock has done this **** two times before, never came out, search the board, honestly like has been said above when it comes out it'll be nothing better than a port matched stocker

 

I think this will drive the cost down on the GM LT4 intakes on ebay

 

Ah, I wasn't aware they had this on the table for awhile.

As for .1 gains, if you're talking the 1/4, I don't race, so that doesn't pertain to me in the slightest. If you're talking power, I find that hard to believe. You're seperating the intake from the warm oil and motor heat. I've always liked how air-gaps looked, carb or EFI, and the LT1 would just be all sorts of cool in my book heh

 

Well, They are on summit website now!!! As for how they are going to function, I really can't see to much gain from them. Yes they are air gap but the runners are almost Identical to the factory intake. I think for the money it isn't worth it, But thats my .02, I wish someone would go ahead and make a single plane intake for the LT1 heads that you wouldn't have to do so many mods to and get it over with! Most of us have the seen the pics of LT motors with single planes and an elbow, and the #'s show the benifits.....

 

I like your idea better. You would think you could just buy one aready modified to work. Maybe the aftermarket still dosen't believe that people love their LT motors??

 

They may be on people's websites (Summit's) but I asked them (Edelbrock) personally at the SEMA show and the rep told me it would be at least March before they are shipping... so I might expect to see one on the streets by January 2008!

 

I chatted With 'Vic' at a race back in the day and the reason they never came out with the was they could not make much more power then stock and no market . now they have a market to replace LT4 intakes

 

Bingo. They see an opportunity to make some money because of the discontinuation of the LT4 and are bringing a old project back from the dead.

 

Link to Summit's listing? I'm not seeing anything.
