It may have begun life as an April Fools joke, but the Holley Sky-Ram intake is the real deal-so real in fact, we put it to the test on the engine dyno at Westech Performance. Watch as our side-show spectacle turned performance part proves it might not be so ridiculous after all.

If that combo doesn't make its way to a Cleetus event I'm going to be thoroughly disappointed in whomever wins it 🤣
Lmao! I was thinking the same the whole time watching this video!
I was just coming on to put simular to this haha... just I think cleet should run it!
If I entered, my shipping address would be Freedom Factory, Bradenton FL. Have them include a Happy Birthday note to Cleetus.
Emilia Hartford just put it on her car and it started on fire.
If I win it. It'll be there for sure...... TURBOCHARGED
I'm so glad you guys took an April fool's joke and ran with it to give what a whole bunch of people wanted to see. 2 thumbs up and I tip my hat to you gents.
I really wanted to see it tested with the moon shot plate system. 😁
yeah! We need that!
💯
BOOM
maybe the person that wins it can hit up westec for that. Imagine every plate shooting 5 hp shot, at varying rpms, one after another till they are all going.
@@frotobaggins7169
Turn them all on at once. 😄
I'm excited to see how the "space ram" performs when it debuts next April!
Space pulls pretty good vacuum 🤪
Yea tons of vaccum great for old school muscle.
6000 ft lb torque at 600 RPM
@@schfiftyfive9680 the lope. Please think of the lope
Next April they will announce all combustion engine components discontinued and start building EV aftermarket parts 🤣
So cool you guys actually dynoed this, someone is good in the marketing department....
I bet some people who are more into a certain marine application might just _love_ that bottom end torque. And on a, say, jet boat the problem of hood clearance might be moot altogether.
I wanna stack like 8 of em together.
It can double as a mast for a sail in a pinch.
I've been told my head is more than a hat rack sometimes.
Or air boat?
You do have worry about fitting under bridges tho. lol.
or every tow vehicle ever. exactly perfect for an RV. Put the intake on the roof and have the runners down through the cab.
@@frotobaggins7169 Nailed it! Winnebago burnout machine.
It added 110ft/lbs under the curve at 3600-3700 rpms, that would feel AMAZING on the street. Guys are always talking about what is going to feel good when you're driving the vehicle everyday vs what is the most "racy" thing. That a Sky-Ram is the best truck intake EVER. I wanna see it with boost. I think the HP curve could be extended a while longer before it falls on it's face with forced induction. I really hope you guys do a Sky-Ram production run. I legit think it would sell out. Maybe experiment with a shorter production Sky-Ram that gives the performance and carries a little higher in the Rpms and still has the insane looks. I think this thing is A joke that turned into a viable product.
I was thinking the same thing. Make it a bit shorter and it'll be an amazing street intake for those relatively stock LS motors that rev up to 5500-6000.
it cut out at 5300rpm, hell that's when my 80e is commanded to upshift anyway. It's perfect for my truck!
Lots of torque and hp at around 3500rpm
@@anonanonski2234 So, you want a relatively-stock engine while having to cut a hole in the hood to make some extra torque down low...
I despise holes in hoods, and it's even more ridiculous when it's on a low-power vehicle. I better be seeing at east four-digit dyno numbers before you're cutting your hood.
@@anonanonski2234 What LS only revs to 5,500rpm? LS1 in the late '90s camaros is the lowest revving LS engine and it redlines at 6,000rpm.
That torque curve is fantastic. I almost never take my big block Chevy over 3500 rpms. I don't care how much power it makes at 5000 rpms.
I'm glad you actually built it and tested it! Way to go Holley!
I love that the runners are SOOO long that it not only hits the fundamental resonance, but the next mode up at higher RPMs. Finally, vtec for your stump puller.
I learned something , Holley is cooler than I thought ! I use lots of Holley products and thought they were very cool before .....
So, what I learned from all this is it would be excellent for my mud truck!!
I thought mud truck as soon as I saw the graph.
swamp buggy as well.
No need for a snorkel in those deep water crossings lol
@@stevengaskill6515 right!
Dear Holley, I think you should create a modular Hi-Ram intake where the middle of the runners has a bolted together flange, that way the intake could be run like normal and you could sell runner extensions in 5 and 10 inch increments, that way a guy could choose how much "Sky-Ram" he wants or he could even keep adding them until he has a Space-Ram. Seriously thought, you could increase the runner length by 5-10 inches at a time and tune the runner length for your application on the fly to what best suits you.
Or what suites the track that day!
That Sky Ram intake would be perfect on a old school 1966 Dodge A100. With the ingne behind the cab and a old school dual cuad air ram filter scoop. And a dually axle in the back and supper single tires in the back. With Dual exhaust stacks in the back of the cab. It will almost look like a Hot Wheel style trick out truck. That would get allot of attention. Much more than someone with a Lamborghini.
Then put some meaty bois on it
@@savagesock3598 That's what he ment by super singles. They are a 455 width tire (17.5" wide.) That's what I want to put on my 95 Chevy single cab dually.
You have good taste in automobiles.
I am pretty sure this build would quickly land in a hot wheels blister... 😁
@@c0c0asauce I prefer dual 275 drag radials myself.
Never thought you'd follow through with this.
Well
If it's fun, it's worth doing
Well done y'all
Nice to see someone who knows how to tighten AN fuel lines testing this
The only intake where you need to consider wind drag while running it. 😂
Awesome!
With that piece I wont need to install a snorkel intake on My offroad truck!!
😂👍
or the florida swamp buggy.
I would love to see a carb test with this and measure the temp at the intake port. Though installing two carbs 10’ off the ground would be quite the challenge 😂
Mad props to Holley for following through with what was really just a funny April fools joke.
YES!!!!! SOMEBODY actually said "high end torque!" It always gets spoken as low end torque or high end horsepower when in fact the force turning the wheels is ALWAYS TORQUE. Horsepower is just a calculation. It's math, not a force turning the wheels. Thank you Steve, it's about time torque gets acknowledged at all engine speeds.
Correct 👍
OMG I'm so glad you guys did this! Thank you Holley and of course the legend Steve Brule himself 👍
It makes me so happy that this was real, and wasn't just made of plasticine or something for April Fools :-)
The fact that the joke actually works as intended is hilarious.
Do I smell variable intake runners coming?? I'm imagining another intake about 2/3 of the way down. As RPM creeps up they blend their throttle body openings to maximize area under the curve 🤔
Been a thing for a long time on OEM cars
I was praying for this, so awesome to see how much of a difference it made. At least it does have a purpose even being as ludicrous as it is. Love it 🤣
I love that Holley can make an April fools joke, and then take it to the extreme and test it. I would fall on it's face at upper rpm ranges, but the looks you'd get at the track would be priceless!
I love the fact they actually made it. Makes the April fools video even better
Now dyno the sky ram with 2 carburetors on top
I want to see this ran with twin carbs on it!!
Somone would definitely put this on their squatted truck with a trash can size exhaust tip. It's amazing how a joke can become reality. Thanks for showing
absolute madlads for actually building the thing! I tip my hat to you!
Looks like something Jeremy clarckson would come up with. I'd love to see Vizard's take on this. That big hump must be the RPM sweetspot for that intake (pulse wavelength).
Yep, and it's probably the first reflected wave, so the signal is very strong. Hence the big hump in a narrow rpm range.
@@michaelblacktree thats not going to be the first wave, you can see the secondary rise at about 4700. Lets assume its about 3600rpm, thats close enough. In one revolution, 360°, sound will travel about 19 feet. Its a reflective wave so half that distance is 9.5'. Its the secondary or tertiary wave. Without the exact cam specs and centreline runner lengths its hard to know for sure. The graph makes me think its tertiary. The secondary is at about 4700 and would make the primary at about 10k rpm.
Garage 4age did a test with 24" extensions on a 9000rpm ITB deal. Chasing the primary wave.
@@timothybayliss6680 you must have a degree in fluid dynamics.......
@@rearspeaker6364 nope, highschool drop out
@@timothybayliss6680 damn!!
4:06.... (VE number) volumetric efficiency is what he's talking about basically saying that this is where the Pulses from each cylinder line up just right to compress a little tiny extra air into each Powerstroke. It's basically where the intakes harmonic frequency is.
Thinking about it as a harmonic frequency helps me understand why a larger one would help low end torque (lower frequency - larger wavelength), and a smaller one would help higher rpm torque (higher frequency - smaller wavelength). Thanks.
I'm Glad Holley did a Collab with Star Wars and made the AT-AT Intake. Very Cool!
Thank you for actually running it!
A limited run of those intakes would be cool maybe 50 of them
I love everything about this Haha truly awesome. Nice work guys!
4:00 He's clearly monitoring the competition.
Now what if the intake was longer and came back down to where it kinda normally lives. Monster chamber
More engine masters🤘
I always thought it would be cool to see what would happen if the intake runners were tuned to have the exact same volume as a set of full length headers. Also, the intake runners + plenum tuned the same way.
Ok, that's the dumbest thing I ever seen.
I want one!
Can wait for Richard to conclude with further testing and with boost.
😀
Imagine a procharger with one of these sky rams
you know this actually frees up some space above the hood where the driver would not normally see through. Sounds great
80’s FLASHBACK! Basically you built a TPI intake from the late 80’s. Long runner length = massive torque but rpm’s done by 5k. Still love the TPI!
Definitely my favorite intake. It was well suited for the 305 which it was designed for but choked of a 350 even sooner.
So are you going to let Richard Holdener play with it?
It's actually cool to see this on a working engine. I knew it was an April fools day joke, and I knew it would change the torque curve pretty radically, but I didn't expect to see 50 lb. ft. of additional torque. That was interesting. Nice to see it actually run.
The engineers of the original 49 Plymouth High and Mighty, with that towering tunnel ram wiuld no doubt approve. Well done Holley.
This is the kind of crazy that sometimes yields big surprises. Not so much this time but, it was fun watching and learning. Time well spent gentlemen.
Interesting that it hit such a wall at about 5k rpm. I’d imagine it’s the combination of harmonics and the restriction of tubes that long. Would be fun if they made one that was multiple sections and could shorten down as rpm went up.
That concept has been put in production over the years, though usually with a valve to switch between two fixed runner lengths
@@DangerDaveMurray also been done with itb it literally two tube that slide in and out to modulate the runner lengths
80s TPI style...
Like a slide whistle but with intake runners
Lots of old drag guys in the 60’s tried the variable runner idea using straight radiator hoses as the runners and cutting them down to the sweet spot. Really interesting stuff
Now I am curious about how the lengths in between would perform, like 10" and 20".
garage4ag did this with itbs its a good watch
Car manufacturers have been doing this for years. Think variable length intake manifolds.. im kinda thinking the bmw v8 had 12 to 18 inch variable length. 18 for low 12 for high revs.
@@kwisin1337 I know of GP race engines that use variable length intake technology but it is a small change of length for them. I am curious about how the mid length intake will perform for low rpm off road 4x applications with the amount of torque that the long runners made.
Guys, 10 out of 10. We all knew what would happen, but the fact that you followed through on the testing to show people how this works... love it. Pure gold. High five guys.
I didn't mind having to wait a month to see it on the dyno. I'm so glad you guys put it on the dyno😏
It would be hilarious on my 2005 impala front wheel drive with an 2007 ls4
They HAVE to make a 6-8inch longer High ram after seeing this. make it Holley
My dad had a 67' wickens f/b , that had 427 chevy built by Louis Unser in it. The manifold on it was a Edelbrock SP-2P shoe box ram. That manifold cruising down the river (1800-2200 rpm) in july at a ambient temp of 112°f would form ice. Making ponies!
So many are you selling Holley. So glad that you actually built it and tested 😅💯 Aussie Fan 🤟🇦🇺😎
It's so cool that you tested it!!! I'd kill to see it with a dual carburettor set-up. I wonder if it would even start.
Yes they will start, on a much taller version (home made) with a carb. czcams.com/video/72fJUTMOAw0/video.html
@@free100x NICE!!! Thanks for the link! I will watch it when I finish work.
@@carculture3376 Your welcome...
Wonder what a cam matched to the powerband would do? How much torque could we get.
We ran a modified Mickey Thompson Pontiac cross ram on the street back in the mid 1970's, with two Carter 750cfm carburetors. Matching the camshaft to this, really made these come alive. Won many a street race with them.
Nice to see Steve in front of the camera. The guy is an absolute guru and a soft spoken man. 👍
Holy balls you actually made it.
This is going to be epic!
I’m surprised it peaked that high in the rpm range.
Run a cam with ridiculous overlap and still have tons of bottom end torque.
We need more of this experimentation. It's really cool to see comparisons between different lengths and diameters when it comes to manifolds and whatnot.
Holley products seem great. Hopefully ordering a terminator x max here in the near future for a project I'm working on. 3rd gen Dakota, LQ4, 4l80e, 4wd. It should be cool when it's done.
I love this. I hope whoever wins this puts it on a AMC Gremlin it was also introduced on April fools day. It would be a match made in heaven
I would love to see this under low boost!
its so cool to see this thing actually being tested. I love seeing some weird power graphs.
Cool dyno test!
A grunt-a-gear tow vehicle would LOVE this 'Sky Ram'.
No need to rev over 5,000 when you can pull a house off its foundation at 3,700 rpm.
what would happen if you put the injectors at the top of the skyram instead of its base??
Cooler IAT, more power
You would get ice on the outside of it with E85 as fuel.
@@timothybayliss6680 lmfao not even close
I saw a test where they moved injectors from the port to the end of the long intake trumpets. The engine gained around 3%
@@boost1728 run the math on it. Enthalpy of vaporization of Ethanol is 841kj/kg/k, specific heat capacity of air is 1.005 kj/kg/k. Even running a 10 :1 afr of Ethanol alone the drop in air temp would be over 80K. 80K is more like 144°f. You only need intake air temps below about 30f for ice to form.
Maybe math isnt your strong suit
I am here all day.
It still looks awesome. Would be fun to see it work with the nitrous from the April 1 video
This was so cool from Holley!! Best ever april fools tricks but then to see it really live🏆 Thanks Holley💪💥
Thank you for doing this!!! I’ve been wondering what would actually happen!!
Now test the Moon Shot....
High torque at lower Rpms would be great for off-roaders
But it would raise your center of gravity. Trade offs....
Yeet
I'm bummed that the contest is only open to the U.S. I so want that manifold. Ultimate man cave item.
Awesome this works so well. And I know the dude mentioned Chrysler’s Ram Induction but he didn’t
say Chrysler put a 30 inch version under the hood.
There’s old Chrysler magazine advertising showing the tubes and a dyno chart that almost matches holleys dyno chat curve.
Except every old disadvantage from long runners and carbs Chryslers fought is gone with fuel injection. Wicked
Find a taller dyno cell, test the moonshot on top of this
I wonder what a lawn mower carb does on a V8 💁♀️
Lol, do you intend to get it dyno tested?
after watching that video i make a point of telling every single one of my car friends about it, the mpg is just sooo good, im sure its some kind of record
Brilliant. Funny too.
Really well put together!
Don't ever change!
For the love of God, please carry on!!
Great to actually see it on the Dyno
I love seeing ridiculous ideas being put to the test and not also not completely failing either…. Very cool 👍🇦🇺
Well, if I didn't like Holley before, I do now. I love a company that's willing to have a little fun. Well done guys, entertained me for a bit and made a new fan. 👍
Like Steve said, it was awesome to see such an exaggerated test. And absolutely amazing that it added 50 lb-ft to an already stout combo.
This needs to be put into production. Even a limited run would be hilarious to see what they end up going into
Thanks for sharing! It is very kool and ridiculously fun!
For next year: fenderwell-exit split intake. Just split this in half, with each half curving out to the side with throttle body and conical filter protruding from the fenders. It'll really SUCK - air.
to be honest my mind went to the chrysler cross ram manifold of the early 60's, and the results confirmed the experiment you provided
I was so hoping you guys would actually do this. Thank you.
This is awesome. They actually did it.
I'm not the sort of person to even consider custom parts for my engine, but the Sky-Ram April Fool's gag followed up by this dyno test was fascinating nonetheless!
Custom parts is how Hot Rodding got started. Nothing wrong with them at all.
I couldn't wait to see this thing on the dyno after I seen it a couple of weeks ago!!
Certainly thought provoking to see those results. it would be interesting to see what something half the length would do. Good people making great content.
I've been waiting to see this, and I'm not disappointed.
I'm not an engineer or anything related but I really felt educated with the explanations presented here!
Oh wow an April fools joke finally airing in almost may. If only everybody hasn’t seen this all over the Internet for an entire month.
WHOA. Its the AT-AT Walker from Star Wars!!
Near the end of video in background as they talk lol
Im looking forward to Space-Ram guys!
Who wouldn't want one? So much torque. Its a giant middle finger right up through the hood.
dude i was dreaming for them to dyno it for the memes and my dream has came true,im a happy man too see this
Cool that you made it and actually put it on the dyno. But like to see more dyno comparison's with the sbc sniper carb intakes single carb and dual carb sheet metal intakes.
