Which SBC Intake Flows More

[@lssux4371]

I've always wanted to see actual intake flow...back in the day everyone slapped a Vic Jr on a SBC and it was adequate enough for a 240 cfm head,but head technology has exceeded most of the older style intakes nowadays...keep up the good work.

[@superkillr]

One of the rare tests you will ever find on the internet. So eye opening. Nobody wants to have a kick butt head flow and then show that a manifold will drag it down into average territory.

[@johnstewart3937]

Great video , was nice to see the very old design strip dom do ok

[@chriscorley4599]

I have Eric’s manifold on my car. Very nice piece makes great power.

[@Comet-hn3gm]

Not completely binge watching, but I am going back through some of your videos, and making comments. Trying to share the love.

[@peterfairlane2065]

Great video , lots of good information. I bet there are people who swear by their intakes of all kinds. And what ever they put together is working for them. Those are the guys who come to the track. Run crazy numbers, them disappear .

[@bruceleroybell8139]

Thanks Eric good stuff. Goes in line with dyno test Hot rod 19 manifold test. Dyno showed 2892 to give the best results.

[@pizzandoughnutspage7817]

Dude awesome test Eric, appreciate the time put in to research comparisons. But I gotta say that Dragon Slayer is an awesome piece, wonder what it’d do with a 7070 tunnel ram.

[@johnnyatkins9097]

Would liked to have gotten an honorable mention on the older style 2925. I am going to be using one on a pair of AFR’s Competition CNC’d 220’s on a 13.1 406 Chevy. But love the info and appreciate your videos thanks Eric.

[@patrickmoore1017]

Outstanding work Eric

[@trestlesrocks]

I know you can’t please everyone, but I wish you were able to include a Holley 300-110 dorton intake.

[@indyrock8148]

This is great Eric. THANKYOU!!!! Personally I have a BMP 4150 on shelf I got when ACCEL closed. Was wondering what it was worth. Seems it will be 🙂

[@teddjordan582]

Awesome video! Thanks for sharing your knowledge Sir!

[@jonathoncouchey7151]

Someday I'm gonna have to send you some aluminum Small block mopar heads to do. But at that point I will have done my research on which heads have the most material/are the best to port.

[@IRONHORSE427RACING]

I've always just believed that the 2892 even though costly was the best out of the box....all we ever do is port match to heads and clean up any rough castings and We have always been more than satisfied.

[@WeingartnerRacing]

They are very good.

[@chevyrc3623]

Thank you for that information now I know what manifold to run

[@Scubasteve22]

Hey Eric. Thx for all your info. We r building a pretty hot street strip 383 sbc with afr 220's . We also bought the aluminum single plane from afr. The dividers are super thick. How good of a manifold is this, and should we skinny the dividers up a little .Thx for any help..

[@YerkitRacingChannel]

Love seeing comparison like this! Those swirl number are interesting. Need more information on this. Does more swirl make more power? Maybe better atomization and helping to complete the burn.

[@davidwickboldt712]

It would be interesting to see how high swirl compares to high flow on an engine dyno. Funny how with all the R&D on 4 strokes, so much is still theory. 2 strokes are even more mysterious. Still new operational variables to discover?

[@jsf74]

Wish you would have done the older 2925. Tons of these floating around circle tracks all over the country!

[@WeingartnerRacing]

Im sure it will happen again some day.

[@josephnubile1970]

Hi I really enjoyed this video. I have a couple of questions. I would like to see you flow a stock sbc Edelbrock Performer Air Gap and one that you have ported or sent to Extrude Hone to Equalize the runners as much as possible and also use a 1 inch open spacer on both that these manifolds respond well to. Second lets say I was building a 11:1 327 .030 over so its now a 331 and wanted 500 hp, so in theory I would use a Air Flow Reasearch 195 with the competition port job. This way smaller cc than a 210 should equal more port velocity. Now, lets say you can equalize the ports in the manifold to say, 288 cfm on average of each runner. Does the head have to be able to flow anymore than that to make power. Its nice to have the big flow numbers but if your manifold cant get you there then should you just buy a set of heads with lower flow numbers?? Or, are there things that I do not know comming into play. Thanks for the awsome content but this is what I think about and would like a concrete answer.

[@gisaac3779]

Thanks Eric. I have a Profiler/Wilson ported. My thought on that is when not port matched the runner entry was rather small and tapered in to allow for a port match. If possible could you comment on that compared to the others that were tested? I remember the center divider at the head face between ports being extremely wide maybe 5/16”ish with a taper from about 1” in the port exit to the flange face. Been a few years now though but in my mind that would kill it without being straightened and sized.

[@allenredmon6004]

would love to see a flow chart on weiand track warrior 7620. another great video

[@nickorozco9177]

Great video ! Curious if youd do anything different to your ported intake on a 25+ lbs of boost , blow thru carb combo ? Ive heard plenum volume becomes a much bigger concern than port dividers extending into the plenum on a 1000+ hp sbc ?

[@tjed1071]

What do you think about the AFR #4811 intake? Looks just like a super victor but different on top… any advantages with that design?

[@timothybayliss6680]

I would really like to see a L98 tpi intake flowed like this. They are so sad.

[@gabrieldimarco9646]

Thank you Eric.

[@drivinwithdrew7676]

Really nice info! I’m running a holley strip dominator right now, could be wrong, but i wonder how much the port air speed has to do with swirl, or if the angle the air comes around the valve through the chamber has more effect? I know it not a real reasonable thing to do, but it would be cool for someone to do a fresh intake manifold test on the dyno

[@superkillr]

So what do you want if you have to choose.. more swirl or more flow?

[@anthonyking4387]

Hey bub, my truck on methanol wt a 2975 ran 30 xs 6.88 most of them wt a 8! It is dialed on a half of a 750! It runs 6.38 et wide open! Im wandering if a 2925 intake would need a jet change? PS. Same question on a bigger header? Im running 1.3/4 & may go bigger if i can just raise fuel psi

[@DevastationMtrsports]

It's hard not to notice you didn't use one brodix, intake that's very interesting.. ii looks like the Super Vic 4150 is a top choice here.

[@WeingartnerRacing]

I didn't have any at the time but if its a Brodix intake and it says HVH on it they suck out of the box. The others are good.

[@DevastationMtrsports]

@@WeingartnerRacing .. right on. I'm not a fan either. A good friend bought an El Camino with a good 388 ABC. Oliver Ross, I think Calies crank.. dyno I think was 526 at 5900 or like 6200.. has an HV 1014 on it.. small port version. IDK the cross section yet but I think he can make more power just w an Edelbrock, even an older Super Vic.

[@nickorozco9177]

@@WeingartnerRacing how does a ported brodix hvh compare to a ported 2892 if you did the porting ?

[@WeingartnerRacing]

@@nickorozco9177 any Hvh intake is not very good.

[@gdfitzgibbon]

This may be a silly question. Intake flows X amount, more horsepower with a head that flows more? Or a head that flows the same. I guess the question is too much head for the intake kill hp?

[@jacksonbermingham2168]

fair enough.. it kind a makes sense.. the coeffiecent of thew swirl is weird at a guess its a self meter for u .. if u know a good number dyno and mani flow for a certain build i think it will be relevent other wise you could run nissan r35 gtr airflow meter in the cylider wall there supposed to flow 550 cfm or something it maybe read something.. another way or even better before the the carby because it will only draw the air it can flow kinda likek a dyno carb swirl hat

[@jacksonbermingham2168]

also the 35 gtr has reversion flow build in so maybe if u could bolt it in to a carb spacer its probably 2 inch wide or 1.5 ... it could give you maybe a reversion pulse to if flipped if the the valves was say running at 7000 rpm .. at a guess u kinda want to minimise reversion back up from inlet valve specaily carby although it could add more atomisation probably why long runners do so well .. i can understand having bulk volume on super vics the air has some where to go the reversions slower and the track ks easier on draw ins .. i guess does that reversion pulse of atomised gas cool the air charge and aslong as it doesnt reverse draw on the carb jets it shouldnt because v8 a ITB weber it could

[@jacksonbermingham2168]

this swirl has opened a can of worms specail reversion pulse to feed other cylinder . like does reversion pulse help feed next cylinder intake stroke or hinder it because the intake swirl to carb entry clash.. fight each other in the plenum makes sense plenum volume helps free the air for repurpose of direction

[@jacksonbermingham2168]

can u get a intake swirl meter on a dyno and figure out the pulse intake swirl on a engine dyno .. cant rememer what there called the machine that spins up engines for value terrian testing
