Edelbrock Victor Jr. Intake...
Edelbrock Victor Jr. Intake... I have been reading the pretty heavy debates on the single plane intakes like the Victor Jr. along with the GMPP Intake...Most of these threads were posted back in 06', so I was just wondering if any testing or any other information has been posted since. I am debating on making the switch to the single plane with my Procharged setup. I wont have the 346 cu. too much longer I will be using a 400+ cu. motor made for some serious boost. My goals are 850-1000 RWHP...or more 
So with all that being said here is my questions for debate/discussion...
--> How does the Victor Jr./GMPP single plain intakes compare to say an LS6 intake on a FI/DD that typically runs about 9-10psi of boost?
Also...When I start building my new engine here within the next month or 2...When used on this high HP FI application will the single plane/intake elbow/90mm Nick Williams or similar have an advantage over the LS6 intake...on lets say 750+ RWHP...Now this car will still need to have some street manners because my design is to create a Super Street type setup...if that matters in this discussion...
Now typically with a stalled auto tranny the cars rpm's and the power band will stay at 3400+ RPM's up to around 6500 or so (On my Car)...Which just so happens to be the power band of the Single Planes...(3500-7500 RPM's)
*** The reason I have gotten this interest on the single plane is I see alot of the big FI dogs running these type of intakes making big power/and running some nice E.T.'s
Now before I get chewed for saying that...I have seen many 700HP+ cars running LS1/LS2/LS6 so I'm not sayin by any means that it can't be done or be efficient, but i was just wondering some of the NEW opinions on these intake comparisons!

Like you said it's mostly the big HP, big boost guys that are benifiting from the carb intakes. Mighty Mouse and KP are pulling great #s with their ls6 though. I'm running one, but I got it for almost half price otherwise I'd be still running the ole ls6.
Yea I am going to be able to get the Victor Jr., elbow, and 90mm TB for just a little over half price...That was the main reason I was looking into it. Thats also the reason for trying to find some more information and comparisons
Also some opinions for a yay or nay for my setup...
A few questions...
What is your opinion on the Victor on your setup?...How much boost you running out of your turbo setup?
Also Is yours a street/strip? Or what kind of driving do you typically do in your ride?

If its a stock car or close to... why would a switch of intake change the cars performance at the drag stip at all. Hell even if its an agressive setup and the cam profile is wrong for the vic Jr... its not going to gain anything over the ls6, but thats not the intakes fault.. its because of a mismatched setup overall.
To take full advantage of the Vic Jr.. You need an agressive setup with a cam designed for the Vic Jr. Most H/c cars will see a benefit of running the Vic Jr over the ls6. Some people on here even believe that for a pure race setup the Vic Jr is better than the Fast 90, especially after some light porting/ portmatching, which anyone here can do in a matter of a few hours.

I'm running the Victor jr. with a FAST 90 TB and an Aaron's elbow. I don't have any experience personally with the FAST 90 intake or even the LS6. I went from an LS1 to a BBK to the Victor. I can say that the BBK was a definate improvement from the LS1 throughout the entire powerband. I can also say that the Victor jr. has a definate improvement over the BBK from mid-range to high end with the bottom end being a little softer. Also take into consideration the TB sizes with each manifold 75mm - 80mm - 90mm. I made the switch merely because of better air distribution between cylinders and the cost was half that of a FAST 90 manifold and included the fuel rails. Your probably going to get many different opinions on this one. To each his own, I'm happy with my set-up.

I originally put a carb intake on because it looks nice 
Now I actually need one because of my fuel setup.
Pretty sure it didnt gain me any power at all though....but who cares ?
As for a 90mm TB, seems like a waste of time when most IC plumbing is 76mm OD ( 3" )

The runners on the Vic Jr are not equal length, the ls1/6 are. W2W has tested an ls6 manifold with a wb in each primary tube and found nothing to show that is was not getting equal amounts of air/fuel in each cylinder.
I am using a Vic Jr on my 370 turbo build.
I purchased the 78mm elbow to save 400.00 on the TB.
Now i can reuse my P&P stocker.
I didnt see the 90mm doing any justice with 3" charge pipes either.
Its kind of like putting a 2" valve on the end of your standard water hose and expecting it to flow more water IMO.
Now of course if you have 4" charge piping it would only make sense to use a 90 mm TB.

I was under the impression that most F/I guys switched their ls1/ls6 manifolds to the Edelbrocks to prevent the notorious leaning of the #7 cylinder.

What about turbo/blower to IC plumbing ?
I just dont believe that most boosted LS engines would see an 80mm TB as a restriction anyway, say up to, or maybe over 1000bhp.
( and yes, I went with 85mm lol just because I wanted to )

I'm going to say this slowly so you understand...you...are...wrong. If you buy into the hype then....well you just buy into the hype. Read correctly ls1 nutjob, YOU WILL HAVE MUCH BETTER DISTRIBUTION WITH THE CARB STYLE VERSUS AN LS STYLE MANIFOLD, NO QUESTIONS ASKED!!!

Second I am useing a single plane on my build and I am not buying into any hype. I simply pointed out two facts 1 the runners on a vic JR are not equal length and 2 the testing that w2w has done and what they found. There are many people that think the no 7 problem is not do the air distribution in the manifold. Also people have turned ls6 manifolds around and still had problems with the no 7.
You seem sure of you self. Have you done any testing that will end this debate? Other that talking slow?

The important question always gets skipped.
Has anyone seen or heard of any problems with #7 after the vic install? I personally haven't, but would like to know if anyone else has.

I use the Vic Jr. on my set up. I used it first because i thought it looked better and then as the more boost I put to it, I feel more comfortable having it. The higher HP and higher rpms will benefit from using the Vic Jr due to flowing better and distribution of the air as well!.But I have seen some rediculious power from the LS6 intake as well! Personal preference I guess?
