It would be interesting to see how the air gap would compare

[@jesse75]

AG. Over rated. You can take any intake and make it an air gap.

[@jasonpunty7633]

​@jesse75 lol no. The air gap has air under the runners for a cooler charge. The cut out in the separator is not the "air gap"

[@bluecollarhotrods9781]

I know it didn't get tested, but it feels like on this combination an RPM air gap would be the clear choice. The regular RPM was only down 7HP at peak to the victor jr, I'll take the extra power in the midrange. I'll go out on a limb and say that the RPM most likely made the best average power too.

[@hardball107]

The air gaps do work very well with throttle body FI but are very cold blooded with a carb, I have 4 of them sitting in my garage from different engines that I have changed out for friends because of stumbling, hesitation and driveability issues. I believe you could tune out those problems but the people that I changed them out for want simplicity, that's why they stick with carbs and not so perfect mixtures and tuning. I'm an F.I. guy and I understand their point but it's something to consider for a street engine.

[@samuelriester1419]

@@hardball107 I run a wiend stealth port matched to some AFR renegade 185. It's a tall dual plane that can handle RPM up to 6500 but isn't a true air gap so it does a little better in the cold. I like it, but I've never owned an air gap so can't compare.

[@johnsheetz6639]

Victor needs more cam and compression in this case. I bet with a solid roller profile and about 11 to 1 or more able to take the edge

[@BrandonLeeBrown]

The RPM Air Gap acts too large for a stock stroke 5.0. The Weiand Stealth actually beats the RPM and the RPM Air Gap everywhere on a Ford 5.0. The old Weiand low rise two plane beats the Performer 289, but Weiand has replaced it with a not very good imported intake. The Weiand X-CELerator beats the Torker II. This doesn't hold true on the 350 Chevy, but it sure does on the Ford 5.0.

[@johnjones928]

Have to say I'm impressed with how well the 289 did compared to the RPM, especially considering the latter can support 500 hp.

I had to use the old performer for the hood issues. I didn't have a cam so it works out okay with the 1850 model Holley. Miles away from the 2bl. I would guess I gained about 30 hp which is pretty big considering I was probably making about 150 before

[@hardball107]

One thing you didn't touch on is the cold bloodedness of the air gap manifolds. Maybe you don't experience it in warmer climes but here in upstate NY during the summer nights can be in the 40*-50* range and we rarely hit air temps in the 90's. The air gaps do work very well with throttle body FI but are very cold blooded with a carb, I have 4 of them sitting in my garage from different engines that I have changed out for friends because of stumbling, hesitation and driveability issues.

RPM Airgap with a 1 inch open spacer for the WIN !

[@Mr357Cleveland]

It's the old story, the dual plane will be better in traffic but inferior when you're having a real go. Low end torque is good for towing, not for traction. Have a look where your rpm's are when you're going through the gears at WOT, it's single plane territory. You can't have everything in an NA application.😉

[@rotaxtwin]

Hood height (or lack of it) is a real bitch. I don't have a Fox body so I don't know how much underhood space there is to work with but I have an '86 Firebird and it is TIGHT under a stock steel hood. Can't see how I can go beyond a regular Performer. Looking at that Victor Jr, it is a great design no doubt but it needs some serious space, especially if you're running it with a proper filter assembly. Kudos to the Torker for doing better than I expected. Might be good if you're running a nitrous plate to keep everything under the hood. No shortage of space on the dyno, huh?

[@fiend_metal]

I always like seeing contalent that is not just showing peak power but also gives info on the drivability of different combinations. Most of my daily driving, I don't get past 4k rpm, so making power in the area that I am driving is more interesting to me.

[@chestrockwell8328]

And conversely on my road course track day 306 rarely sees below 4k while on track. And this here is why we have options. You need one style, I need another.

[@fiend_metal]

@Chest Rockwell exactly, I also love information for my racecars, but it's just nice to see good quality comparison content. Not just the usual "your cars not fast unless it makes 4 digit power..." that seems to clutter a lot of my feed at least.

[@chestrockwell8328]

@@fiend_metal Big power is a relatively low cost game these days thanks to much better OEM platforms and cheap turbos so everybody has got be a 1k hero. Most people can't even fully use 400-500 hp, but those numbers sound "weak". Not to me, I'd rather ring the neck of a 300 hp well balanced car all day than to be nursing around so much power something will break, overheat, no traction and so on.

Usually I am trying to kill low end torque from 377, 383, 406......on the street. At most I am running a 275 radial tire......and usually something in the 255 or 265 realm.

[@duanedahl8856]

I had a very similar combo, using the Lunati Voodoo cam, and a Holley Sniper EFI...the RPM intake has fuel distribution issues with the Sniper, and kept fouling a couple of cylinders, BUT it all went away with the Victor Jr...both setups has big street performance for a measly 306 CI

[@klaver3913]

Apparently, the Sniper's internal MAP sensor reads from only one side of the dual plane - only 4 of the 8 cylinders. It needs to "see" both sides of the manifold to run properly. Milling the divider a little seems to solve the problem.

[@scotttimpany2845]

Very surprising to see the similarities between the Victor Jr and the Torker II in this application

[@the15car]

Great comparison. Do you recall what the jet combos were for dual and single plane?

[@keithwiebe1787]

I built up a 302 in my 83 Capri and put on 351 W heads and mild cam, headers with the T2 years ago and used the stock Holley carb. Had to drastically change jetting at full throttle but part time throttle didn't need to change much. Don't remember the difference but it would fall flat with stock jetting. Now, 30 years late with these dyno charts I should have kept a dual plane. We were told years ago that single plane intakes were the way to go.

@@richardholdener1727 a modified high rise dual plane intake with a balanced average runner flow over 320cfm with the divider milled 1/2" down with a 1" open spacer will go past 7,000rpm easily and support just as much power as a out the box Victor or tfs R single plane manifold but make more low end torque. We have had many customers wanting their low end torque back but not lose the power up top so that's the combo we go with.

I have a question. I'm looking at tunnel rams for a small block Mopar. I found several different brands. But some have a single carb set up. Some have dual. I can't find a comparison anywhere. Which is best? Or would I offset the single by adding a larger carburetor? If you haven't done a comparison?! That would be cool. Weiand vs Edelbrock vs Offenhauser etc.

dual quad would be better

[@pezzonovante888]

Would be really curious how a ported "Performer" would work with AFR 185 heads on a 347. 650 Holley. Mild but not factory cam. Hood clearance is extremely tight and completely prevents the use of a higher rise intake. Far from ideal, but a reality nonetheless! Cheers

I'd like to see the victor jr vs victor jr EFI the one that's the same thing but outfitted with injectors and fuel rail, is the powerband going to be about the same but with improved drivability? It's prob out there but overall which makes more peak power the carb style EFI intake or the factory style EFI? If I'm not mistaken they make a victor 5.0 factory style EFI manifold. Or even a victor jr vs a high ram same jist, I would think the carb style intake would make more but I have no reason to think that just a guess. Weingarner does not like the new Holley low profile open plenum EFI intake, he said it's basically a worst of both worlds, Typical poor low rpm TQ open plenum chachteristics but poor high rpm capabilities. If you hate TQ and you hate high rpm HP it's perfect! I just scored an old 701R-36/300-36 sbc Holley contender for $75, hope it's what I'm thinking it is which is kind of like an old Z28 intake the OG performer rpm style intake, either way it looks cool.
