I am seriously considering using one of these manifolds on my 88 l98 over a miniram for the main reason that I might go forced induction down the line and would like resuse the manifold. That and I think it would be cool to do something different. Other than that, are there any reasons to use a single plain over a miniram in N/A aplications. C.I. Will be most likely be 383. This listed spec rpm range on these two are very different (2000-6000 holley and 3500-8000victor)which would lead me more to the holley. This engine is going to be a street-autox-1/4mile use.

Holley 9901-101-1

Both manifolds have fuel rail kits availble

The main concern for me is the elbow. I have heard that these pre fab elbows are flow limiting...

ls1 style adapter

are there any issues using an ls1 throttle body for instalation?

Is anyone interested in making or selling me an elbow so I can use my stock throttle body instead? If someone is interested, which one of these manifolds has the lowest overal height?

Tuning? I have heard that these converted manifolds tune very close to miniram tunes, is this true?

Please anyone with experience chime in

 

Reasons to use one over a min-ram are, the single plane intakes have longer runner length and better air distribution. It makes aa difference espc in a forced induction motor, but most people don't run into problems that can't be tuned for until they get way up over 8-900HP using the min-rams or LTX intakes.

The Super Victor is going to be taller and have longer runners. It'll also be harder to package under the C4's hood (I know I have one on my LTX), but it can be done.

The Holley intake is shorter, has a smaller plenmun and shorter runners.

To add to the fray there is also an EFI version of the Edelbrock Victor E, Accell offers one similar and the Professional Products Super Hurricane EFI are also availiable.

As for the elbow/TB adapted. I had one made up to use a std 58mm L-98/LT1 TB or AS&M Mono Blade. Limiting induction? Even on mine, the elbow is 3 3/8 tall at it's shortest point and 4" across at it's narrowest point. That's a lot of plenmun volume when you figure it's about 12-13" long.

You could convert to a LSX style if you wanted by adapting your TPS to work, then figuring the IAC wiring and throttle linkage out.... Some of it may be the same or work with a little rigging but but I don't know.

As far as tuning. They tune NOTHING like a min ram or LTX intake.

I'm not the only one here with one (I think I am the only LTX with one thou) so maybe some of the others who actually run one will drop by with their thoughts.

There was a guy on the parts forsale section that was making single planes.

 

nope it will work. Just got to splice in the TPS and IAC sensors. LSX sensors use the same voltage signals as L98/LT1's so you just have to splice the LSx connectors into the stock ECM setup

Stock ECM should have no problem handling a single plane EFI setup. My 89 MAF system is more than enough to handle my 383 which peaks at near 6300 and makes 400whp or a touch more now

Will the tune be similar to a similar motor but with a miniram? I dont think as above mentioned but you should have no problem dialing it in from a miniram base tune but i could be wrong

 

Here is a link to an elbow that is currently available using a LT1 or L98 throttle body: http://www.860performance.com/catalo...47&section=128
I have this one with a nitrous spray bar built into it just above the base.

 

Kens80v, how is the power band naturally aspirated? Do you have back to back dyno graphs? Motor specs?

I'd like to see how a SP runs converted to EFI without forced induction involved. Seems most I see have some type of power adder.

Thanks!

 

I'm building a few different fuel injection setups for a future application. I haven't installed any of them yet. The one in my avatar is the same single plane manifold with a edelbrock elbow and LS2 fly by wire throttle body.

The Super Victor is going to be taller and have longer runners. It'll also be harder to package under the C4's hood (I know I have one on my LTX), but it can be done.

If the runners are longer, I wonder why is says it has a higher powerband than the other intakes. Im looking for a single plain thats has the lowest band possible while still having huge flow possibilties


To add to the fray there is also an EFI version of the Edelbrock Victor E, Accell offers one similar and the Professional Products Super Hurricane EFI are also availiable.

Does the hurricane efi have a fuel rail kit? I saw the victor E with fuel rails, nice price but the power range stated was 4500 + ... Maybe not the best for my appliacation. Is there any truth to listed power bands? Won't having a 383 somewhat lower the powerbands and also make up some bottom end?


As for the elbow/TB adapted. I had one made up to use a std 58mm L-98/LT1 TB or AS&M Mono Blade. Limiting induction? Even on mine, the elbow is 3 3/8 tall at it's shortest point and 4" across at it's narrowest point. That's a lot of plenmun volume when you figure it's about 12-13" long.

The flow limiting comment was only in reference to the edelbrock pre fab elbows for ls1 throttle boddies that look tiny. I had no idea that there even was an elbow being sold for the l98 lt1 thrrotle boddies. Its a bit expensive but nice to know its out there

As far as tuning. They tune NOTHING like a min ram or LTX intake.

If that is truley the case, does that make mailorder tunes out of the question?

 

Awesome, I had no idea! Although I am almost getting the nerve to draw some plans and hand it one of the millrights at work! I'm sure they would charge me more than 100 bucks

 

It has a higher power band because it has a much larger plenmum, and runner crossectional area. Simply put its a bigger intake and will feed a bigger motor and/or more RPM.


Yes the Hurricane has a pre fabbed fuel rail/regulator/line kit.

There is some truth to the advertised power bands, when used on the size motor and type of carb they desgined the manifold for....

And yes having a 380+ inch motor will affect the powerband (lower). When you use these intakes with injection, things get out of wack a bit but the basics still apply, smaller intakes work at lower RPM and bigger intakes work at higher RPM. Nothing (other than variable length runners) will make power from idle to 10,000RPM. There are trade off's your going to have to deal with as well as packaging concerns.

As for which one is best for you. How much HP are you trying to make and whats the RPM range? Quite a few of us here could make a solid recomendation on an intake if you give us those 2 things.

Some of the mail order guys have experience with running these type intakes and could hit it pretty close if your not too radical on your heads and cam. The best thing to do is tune it on a dyno.

WOw thanks for the link !!!! This is very very interesting for me and helpful !!

 

How about a dual plane modified for efi? Pick up a used on and spend a few hunred having bungs welded in, a generic fuel rail kit and elbow.

This will be my post Santa-brought-me-a-spool-so-I-can-weld-aluminum project.

 

I am basically looking to get it close, then dial it in later on.

 

i've thought about it, but I think with a 383 I will be able to use a single plain and get the desired power band. I guess it's not out of the question though

 

IMO for a 383 inch motor running in the 3000-6000rpm range I would use the ACCEL 74139 or the Victor E.

Depending on the heads and cam I think the Victor E would make good TQ as low as 3000rpm (and pull past 6500rpm) but the Accel is slightly smaller (almost a direct copy of the Victor JR) and would pull more TQ lower while still being capable of making power at 6000-6500RPM.

Personally I like the Accel slightly better.
Will

 

The shortest manifold is the Edelbrock Victor EFI at 4.58" Next would be the Holley at 5.5". The Accel ProRam (which I have)and the Super Victor Vortec are the tallest at about 5.75". The Super Victor is meant for Vortec heads and isn't drilled for a standard Chev bolt pattern.

I would recommend the Victor EFI. I just didn't care how they mounted the fuel rails to the manifold. Jeb Burnett was selling/modifying Victor JR manifolds at one time. You might try and PM him if you want the lowest possible carb pad height.

 

is there any places doing single plane conversions? that would open up alot more options if you coudl get a carbed manfold and have it converted

 

? Have you clicked any of the links? There are many

 

The guys running the non-LTX engines will need to contend with the water crossover issues. None of the elbows shown will clear the water crossover / t-stat housing on the SBC intake.

Food for thought.

...good point...you'd need a "Remote Thermostat Housing"; like the LT conversions. There are many places that do fabrication work, but I remember WWW.IntakeElbow.com was mentioned a year or so ago. If they're still in business, they can do Intakes or Elbows. I'd think a Victor Jr. would work well on the average street motor (4.58"). I still can't come up with a readily workable method of useing an Edlebrock RPM Manifold without a raised hood.
