Installed Super Victor today WOW!! This manifold feels like a pumped up Dual plane Top end performance enhance and seat of pants says bottom end improved. Don't let anyone talk you out of this manifold for Vortec headed SBC.Will be off to the chassis dyno next Saturday to see if any improvements over 297HP and 435lbs of torque at the rear wheels and at 5,000 ft altitude

mello,

please keep us informed....alot of us have similar combo's to your and would love to see the improvments...got an et?

Mello,
You're correct! http://www.camaros.net/forum/biggrin.gif
I've run both a Victor and a RPM intakes on two different Vortec-headed motors recently in my Camaro. BIG difference in throttle response. Sold the RPM! IMO, the single plane Victor is the only intake to run on Vortecs. I've been saying this for quite some time...

Will do.it is going to be a long week waiting for Saturday.I made the change due to the advise of fellow performance addicts on this and the chevelle site so "Billscamino" thanks because I have probably read what you had to say

I replaced my ported Team G on my healthy 383 with an out of the box Super Victor (not Vortec) and even with the larger manifold throttle response improved (which I didn't think was possible on this engine) as well as bottom end and top end. So far I have picked up .02 and 1 MPH in track performance, but I'm not done tuning yet, so there may be more in it. Definetly an outstanding intake.

I too am interested in this intake. Do you have any of the lower RPM data from your dual plane dyno run so you can do low-speed comparisons?

If memory serves the dual-plane ports are much smaller than the Fastburn head. Can anybody confirm this?

Thanks.

I have the super victor on my vortec 383, it is great, but Ive never had a RPM on there. I wonder what would be a good spacer for the super victor??

CarlC, the fast burn intakes are quite a bit bigger than the RPM intake ports. My super victors ports were also alot smaller than my ETEC heads intake ports,which are alot like the fastburns.

Let me ask this.

Since E-brock is making the "roval-port" BB heads for GM, are they making the fast-burn heads for the SB too?? pdq67

PDQ: No, they don't make the fast burns, but they do make something very simlar. Its a 200cc intake vortec style intake port with a 64cc chamber and 2.02 x 1.60 valves. Claims to make a few more ponies than the FB. Cheaper too...

Should that say 345lb of torque at the rear wheels? If not then that's go to be some kind of torque record for a pump gas 350. That's got to be close to 550 at the crank. That's about 30 more then my 468 http://www.camaros.net/forum/eek.gif .

Hey Mello,
How high are you spinning that motor with the vortecs? What rpm are they good to?

Your setup sounds very similiar to what I want to do to the 327 in my garage to put in my Nova. XE274 cam, good manifold, good heads, 5-speed, and spinning to about 7,000 rpms.

I've heard the vortecs won't go much above 5,000 rpms, so I hadn't really considered them.

Thanks,
Bill C.

PS. Do I get a ride if I come to Ft Collins? Probably will next month!

I agree with BillsCamino, my Vortec headed 350 revs very well past 6,000. I have the rev limiter set at 6400 and can hit it easily if I am not careful.

All I can say about the 435lbs of torque is that's what the computer said and printed on the graph. Like I said I am going again Saturday so we will see maybe a mistake. I was suprised. As for the engine it will rev willingly and pull to 6500 I try to keep it at 6000 but it does not slow down. The vortec head will make torque with the correct cam. The comp XE 274 was a wonderful suprise. So much torque. that was the reason I started looking into ways to improve top end. had plenty of low end grunt

I made 365 rwhp and 450 ftlbs. of torque on the rear wheel dyno with a 350. I think the torque # can be off depending on the kind and amount of stall you have.

NC69RS, can you tell us a little about your engine combo?

Glad to hear the vortecs are not limited to the lower rpms, that will enhance my choises as far as heads go. Does anyone happen to know or have a link to flow numbers of the vortecs? Are there different flavors of vortecs? And lastly, is the Super Victor made for the vortecs, or did you have to modify it?

Thanks,
Bill C.

Thanks Bill, that's exactly what I was looking for! But don't the vortecs come in an aluminum version also?

Bill C.

BC,
The aluminum version you're thinking of are the 58cc "Fastburns". Similar to vortecs but not exactly. Here's an article comparing them... http://www.findarticles.com/cf_0/m0BUW/3_40/59460841/print.jhtml
This article also reinforces what we've discussed here about the Victor intake. http://www.camaros.net/forum/smile.gif

Well back to the chassis dyno today.305Hp and 410lbs Torque. 7HP increase about 25lbs torque decrease. Wouldn't know the torque loss by driving it. Torque convertor makes up for it. Air fuel 12.0-13.0 from 2,000-6,000 and that is with 66 primary and 84! secondary jetting in a Holley 750DP.Go figure! I am very happy throttle response is great and it pulls hard from idle to 6,500.Just a note for everyone, the dyno is a Dynojet Reserch Dyno located in Cheyenne Wy. 6,060 ft elevation.I recommend it to everyone with enough cam and convertor sure wish I was at sea level. To MarkM ,don't know what to say, but these Vortec heads make some torque. I thought that maybe the computer errored but the torque numbers are real. Just think what they would be at sea level

Mello,
That's just plain awesome numbers Man! Where did the torque peak at? What was the torque curve like? Starting at like 2,000 rpms?

For that altitude, I cannot believe you run that much sec. jet! I live in Colo Spgs at 6,200 feet and even my big-block only has 68 sec jets on a 750 3310! Maybe I'm missing something!

Anyway, that's great and thanks a whole bunch for the feedback, think I just found my direction!

Can't wait to get a ride when I get up there!

Bill C.

Bill Torque peaks at about 2200 RPM tapers off to about 300lbs at 5300 RPM. HP peaks at 5100 and stays flat to 5700RPM but again the huge suprise was the air/fuel mixture running as clean as a fuel injected vehicle. Now what Chevy needs to do is build this head for a big block priced at about 500.00 a piece and make a fortune.

Mello,
I can't be reading that right or you must have made a typo!... 410ft/lbs of torque at 2,200 rpms?!! That's too good to be true! I'm going to seriously look hard into copying your motor for my 327 buildup! Guess the only changes might be using the HOT cam instead on the XE274 as the other thread indicates better manners and more performance with the HOT cam.

Guess there's really only one way to find out!

Thanks again,
Bill C.

mello,

good combo going....wow, i wonder what you'd get at sea level.

last week i saw the print-out of a z06 dyno chart...it made 349HP stock....then after spending $600+ on header & another $400 on an intake....it made a whooping 359HP! the drawback is that it cost him over $1000 to make an extra 10HP, whereas it only cost you a little more than $200 to get you 7HP!!! i'd say you get a better deal going!

czar

I'm quickly loosing any faith in chassis dynos! While I am very glad you were pleased with the seat-of-the-pants results of your intake change, I have to wonder about the dyno numbers a little. 410 ft/lbs at the wheels at 2200 RPM out of a 350 just ain't right. Could the car have been in second gear still? Maybe the TQ converter is still multiplying TQ at that RPM.

I'm not trying to burst any bubbles here but when I did my 383 on the chassis dyno I got a peak TQ number of 369 ft/lbs at 3850 RPM and 317 HP at 6300 RPM. And that is a stroker motor at only 500' elevation.

The operator has to keep the car in 3rd gear when he starts the pull - if you nail the gas in my car at only 2200 RPM in third it would downshift. We had to roll into the throttle at about 3000 RPM just to keep it in third gear. So "real" numbers start at about 3500 RPM on my pulls.

ps. I pretty much got the same results when I changed from a RPM Air Gap to a Vic Jr. Slight TQ loss down low but HP increase up top. I was having trouble hooking it up anyway so the softer TQ hit actually helped my 60' times.

Eric, that's kind of why I made the post I did. I just find it hard to believe that 350 would produce more torque then my 468. It also made more torque then Carl's 406 that has more cubes and better heads.

I thought the corrected numbers account for altitude, temp and airpressure.

http://dynojet.com/auto.shtml
With a quick vehicle mounting time, the Dynojet Dyno allows you to measure, record, and diagnose performance problems quickly. Our new DynoWare EX+ interface hardware and WinPEP evaluation software automatically correct for altitude and atmospheric conditions, producing consistent, easily interpretable power graphs.

Do you know the correction factor used?


[This message has been edited by 89rs400 (edited 07-15-2002).]

There is something weird about your HP and Torque numbers for this engine. Mathimatically they have to be equal at 5250 RPM. You have HP somewhere around 300 and Torque up near 400 if I'm reading your repies correctly.

I would think you would have around 360 to 370 ft-lbs and HP at 5250. Either your HP is to low or your torque is to high.

Can you post a copy of the dyno sheet? I remember my torque and hp did cross real close to 5200.

[This message has been edited by MarkM (edited 07-15-2002).]

They are equal at 5252 rpm. pdq67

Torque and horsepower cross at 5200 RPM. Max torque is at 2200 Rpm max HP about 5200RPM. In response to another post the run was started in 3rd gear at about 1500 RPM Trans did not downshift and no tricks performed. I will post a copy for all to see. I will scan it tomorrow and try to get it posted.I don't know what to say to the couple of skeptics but the numbers don't lie. Sorry if it offends you but the engine performs beyond my anticipated expectations. Everyone is suprised at the performance of the car.

I don't have a ton of experience with autos, but if you are quoting torque at 2200 rpm as your peak for a combination with a stall converter of 3000 rpm...that would be your reason...and that would be inaccurate. Your stall converter is multiplying the power.

Vortec's are indeed excellent heads...I would like a set!
