You are the man Eric for doing far more than Hot Rod Magazine did when they did intake test .

[@WeingartnerRacing]

Thanks for watching.

[@terrywillis5784]

I am so impressed the black rpm manifold did so well. It seems like a great piece for a circle track 2 barrel or spicy street engine. It's probably less expensive than most of the other manifolds as well. That is plenty of usable power for almost any racer.

[@bobvandusen1832]

I believe you are superman knowing your history and living right down the street in brokenarrow from you. thank you for the dedication and passion for power great job Eric

[@BDauto86]

That is why it's such a hugely popular Street intake. It's pretty hard to beat on your average street driver.

[@WeingartnerRacing]

Thanks

[@robertwest3093]

That engine is certainly a Superman. 114 dyno pulls and still going strong WOW! I have to thank you for this dyno marathon. There aren't many people who would spend their own money to test intake manifolds.

[@WeingartnerRacing]

Thanks

[@scottsigmon926]

Man, the Dyno struggles are real and Dyno’s will make you beat your head against the wall!!! Thanks for all the hard work and effort you put into making videos and sharing your experiences with us.

[@WeingartnerRacing]

Thanks for watching.

[@davidwickboldt712]

Really amazing stuff. Nice numbers on the dual plane.

[@magnusdanielsson2749]

Such an heroic effort. Really interesting results. 👍

[@WeingartnerRacing]

Thank you!

[@71honky]

once again thanks for all the info and the effort you put in to get consistent results where possible so we can make informed decisions.

[@WeingartnerRacing]

Thanks for watching.

[@kdeupser]

You must be Superman changing intake manifolds so fast! Great work as always!

[@WeingartnerRacing]

There were two of us so that helped.

[@mayhemmotorsports7002]

Thanks for your hard work. I'm excited to see what the project x heads do!

[@WeingartnerRacing]

Thanks for watching.

[@DSRE535]

This should be a big lesson for a lot of people that try to emulate other peoples Combinations or trying to compare parts on the Internet from Dyno results and you just never know I mean there is just so many variables!

[@jimwilson4639]

Thanks for your efforts. I was impressed with the Motown being all stock and performing so well. Cant wait to see what will happen when you do a head swap. Looking forward to seeing the results.

[@WeingartnerRacing]

Thanks for watching.

[@ramirodiaz4545]

Good to see Richard Holdner isn't the only one putting out valuable information.

[@matt_1969ChevyC1o]

Man I learned a ton from this video. Thanks

[@WeingartnerRacing]

Thanks for watching.

[@stephennelson6041]

thankyou Eric!, herculian effort!.

Again, thanks for sharing Eric.

[@WeingartnerRacing]

Thanks for watching.

[@timothyesmond7358]

I really appreciate that you take the time to try a 2bbl on it

[@WeingartnerRacing]

Yep.

[@dougsmaintenanceshop5868]

Hey Eric, I am wowed by the performance of the black Edelbrock dual plane. I have one I picked up along the way and didn't think much of it. What a sleeper manifold for us street rod/street strip type guys. I have an Edelbrock dual plane air gap like the AFR parked next to it, and to be honest, I'm wondering if I should let someone else be impressed with how it looks. Maybe a couple more tests and flows or whatnot with the black edelbrock dual plane! Thanks for this series. I am certainly enjoying and benefitting from your work.

[@BDauto86]

The Air gap is a solid choice to, depends on cam and head choice but they both work very well for street builds.

[@WeingartnerRacing]

Thanks for watching.

[@terrywillis5784]

Great test and video. Say hello to Gary.

[@chevyrc3623]

That's very interesting how the elderbrock just jump from midpack to the lead just by a burr finish. And the hurricanes were falling back a few spots. But pretty cool and I think if you do change the weight of oil it does change hp by a little.

[@AB-80X]

Good stuff Eric. Hope to see comparisons on properly big heads.

[@WeingartnerRacing]

Me too.

[@wayneskelly4297]

You inspired me to do some manifold swaps at my dyno session last week. My wife went along to help and we were about 30-35 mins per swap. Only 3 manifolds but several carbs and a swap to alky. Interesting day....I will email ya some of the results.

[@WeingartnerRacing]

I would be very interested in the results please email them to me.

[@gasparsperformance9841]

This is some amazing information and possibly a cheap way someone with a small block to make additional hp

[@donaldhalls2189]

It's certainly a in-depth analysis, thanks for sharing, all the best to you and your loved ones

[@WeingartnerRacing]

Thanks

[@jcnpresser]

Man that’s alot of testing!

[@WeingartnerRacing]

I got a workout in.

[@gbenterprises5217]

I have Eldebrock tm1 single plane. This is the only one I've seen.. I am willing to send it to you if interested it was used on my grandfathers circle track modified engine.. I'd love to learn more about it. I absolutely enjoy your videos.

[@JR-The_Godfather_of_Horsepower]

I'd love to see more on that 565bbc you dyno'd a few weeks back. Just some more Big Block Chevy content in general. Im sure you get plenty of that type of work Eric.

[@WeingartnerRacing]

The goal was to make enough on the dyno mule this time to break even then this time next year I could be doing a BBC dyno mule.

[@reloadingfun]

You're no superman? No one thought you were.

[@wheels2199]

Great info Eric, thanks for taking the time to do this and share the results. I have a Holley sheet metal sniper intake (100% stock new in the box) and would gladly pay the shipping to and from to you if you would like to test it. I would be curious to see how a sheet metal intake does against a ported cast and a stock cast intake. If it’s something you’d be interested in doing let me know and I’ll send it to you. Eddie wheels 😬🧑🏻‍🦽👍 from NJ.

[@JohnKopczak]

Eric please say yes to this test.

[@WeingartnerRacing]

How long can you be without it. I may do another short round of intake testing. No more than 3intakes.

[@wheels2199]

@@WeingartnerRacing you can use it as long as you want, it’s a n extra one I had.

[@michaelfackler9716]

114 dyno pulls ,x pi to the 3rd ,wow 120.000 miles on the mule ,sweet ,how far can it go

[@spambeanie2]

having lived on Oklahoma I know mid July to mid August is the best consistent weather

[@WeingartnerRacing]

I would agree. Sometimes it stays the same in September. The only problem is the weather is horribly hot.

[@ChiefCabioch]

By far the best dual plane intake for a small block is the 1970 Z28 LT1 manifold.

[@WeingartnerRacing]

I have one here and it doesn't look to be that good.

[@petertittle7624]

Man you need your own show. Your way better in detail.

[@WeingartnerRacing]

I agree. Someone should pick me up so they can pay for the R and D.

[@my87z28]

Sounds exhausting, thank you for the technical content. I’ve got a couple questions: 1.) How similar is the Motown/BMP intake to the BM1000? They look very similar. 2.) I put a Performer RPM with a 4-hole tapered spacer on my wife’s 383 (10.8:1, AFR Street CNC 195’s, 241/247, .583”, 112lsa, 108cl w/ Holley Stealth Sniper). I’m wondering if it would have been better off with an open spacer instead of the 4-hole.

[@WeingartnerRacing]

They are very similar except the BMP has the dogbone in the floor.

[@quickrodsinc.4244]

I wonder what the old edlelbrock tarantula intake would make?

[@bigskygarage6455]

Thanks for the update. Did the AFR 4811 with the clover leaf removed lose horsepower?

[@WeingartnerRacing]

Yes but its hard to say if the cloverleaf did it or the different weather conditions.

[@shanearmon9683]

Is the winner based on peak numbers alone or average across the rpm band in my thoughts the true winner would be the one with the best average torque and horsepower jmho either way hats off awesome effort

[@chevyrc3623]

Another thing to look at the Motown manafold that finished 4th completely stock against modified manifolds I am curious on how it did on 2 barrol I mean I know what your saying let's see what the 215 heads would do and see a bigger difference but still pretty good results

[@WeingartnerRacing]

I will warn you all of the intakes test with the two barrel this time were very close. Like 10hp.

[@kczbluesman]

Thanks for this. Do you have a list or chart or spreadsheet of results?

[@WeingartnerRacing]

I will have book made that you can purchase to see the results.

[@kczbluesman]

Edelbrock Performer rpm non-airgap with spacer: 544 lb ft! Is that something to look into? Making that happen again/consistently?

[@jacksonbermingham2168]

them super vic style manifolds are that close you start weighing them for weight advantage

[@minigpracing3068]

Can you keep one manifold stock and use that each session to come up with a compensation factor for the day? Sounds like you can just about add 10hp to each manifold for the day to make a comparison.

[@WeingartnerRacing]

Thats the plan.

[@michaelfackler9716]

Epoxy on the corrosion, file or mill it down

[@ericwhitaker2011]

Since you’re in a controlled environment, you can run a thinner oil to maintain a more consistent oil temp and test baseline. I know you’re a fan of royal purple. Use a 0W-20 or 5w-20 full synthetic. You’ll probably get your power back that you lost.

[@WeingartnerRacing]

Not really. I filmed a video that should be out on Sunday so you can see what Im talking about. However all the tests were done with close to the same water and oil temp to keep things consistent. If you heat the oil more you typically make more torque but because the engine is hotter you usually have hotter air temps that kill power.

[@jesseparadis6141]

Thick oil makes more compression

[@tonydowns9424]

Was there any change in cylinder pressure readable by a compression test?

[@WeingartnerRacing]

Never tested before so I cant say.

[@MrTotalmayhem]

did you ever flow or dyno the profiler wilson after port and gasket match?

[@WeingartnerRacing]

No I don't flow just the intake manifolds. Its almost useless.

[@MrTotalmayhem]

@@WeingartnerRacing i understand, was wondering how well that one would compare to all the others you have tested. seems in the sbc performance world that one is supposed to be pretty good???

[@scotthatch4548]

Did you change the weight of the oil when it was changed or type of oil?

[@my87z28]

That would be one of my questions as well.

[@WeingartnerRacing]

I think break in was 30 weight. This was 15-50 for four quarts and two quarts of 10-30. Maximal. I wish I could get an oil sponsor to test different weights. When I was testing for emc going from 5-30 to 0-10 was worth 8.

[@my87z28]

@@WeingartnerRacing, we just pulled the 30w break-in oil out of my wife’s 383 and I put in VR1 20-50, which I’ve run in all my hotrods.

[@InterestingEndeavors]

​@@WeingartnerRacing did you try with hot shots secret for an oil sponsorship?

[@WeingartnerRacing]

No, I guess it doesn't hurt to ask.

[@jacksonbermingham2168]

with the promaxx ccan u atleast flow it compared to the afr before u bolt it up? that way there credibility.. and did u valve job them or off the shelf

[@WeingartnerRacing]

I will flow them stock but I am going to port match the heads and reflow them so I don't have some of the problems I had with this intake test.

[@jacksonbermingham2168]

@@WeingartnerRacing yeh but u cant deck every manifold and port match. I guess every base deck is off anyways. Mayne deck them and do valves. And compare them complete port manifolds

[@jacksonbermingham2168]

Theory but yeh need the subscribers. U camt keep paying for everything

[@mk-xg2kt]

maybe a sightglass in the oil pan to get same level?

[@WeingartnerRacing]

Probably just change the pan.

[@treyrags]

Disappointing that you could not get a repeat on the baseline from the previous testing. I was really hoping to see a true A-B comparison on the cloverleaf

[@WeingartnerRacing]

Me too. I think its so close that is hard to say it really did anything. Maybe on the better heads we will see more of a difference.

[@fluxcapacitor9867]

Great test , wish could’ve seen 2975 & 300-25 but understand their faulty units also the time constraints & time is $ , hurricane results are shocking , kinda like pro max 215cc project x , together a econo power & sadly copy’s of USA ingenuity.

[@WeingartnerRacing]

I really wanted to see the Vic Jr.

[@petertittle7624]

do you have a way to contact you and buy any books you have

[@WeingartnerRacing]

[@davidreed6070]

What oil. Before and after

[@WeingartnerRacing]

same oil brand Maximal.

[@gabrielbryant892]

Didn't do the composite titon afr that stinks

[@WeingartnerRacing]

It’s the same as the afr 4811. They don’t make the afr composite anymore.

[@65chevy27]

You're talking too much. Variants need to be more condensed. Intake specs and results are more interesting and more techninical.

[@WeingartnerRacing]

They get broke down in other videos. This was an overview that’s why I talked more. It prevents me from having to answer as many comments.
