The take away.
The Chevy engineers put together an excellent stock manifold.
Save your money & run a stock ls3 manifold.
S Paul pretty much the take away from all these tests is “Chevy knew what they were doing, just add boost and GO!” Ahaha
if you got money to burn, buy the edelbrock.
Sep G i love the look of that dual throttle body masterpiece, glad it actually performs and does something none of the others could. Hard to justify that price though
Know Bull5hit same thing I was thinking lol I actually thought it was going to suck..
Better yet send the stock ls3 intake into Rick Crawford racing for his rod mod. 🏁
Remember back in the day when anything was better than stock?
245 hp was “fast”
Owens Racing 400hp was super car level lol
And 1000hp was impossible unless you were sponsored
I membeee
Right. I remember when 12s were the shit for a street car.
Richard you are a diabolical genius! All of your videos are so helpful, educational and fun. Wish I could subscribe twice. Thank you!!
Glad you like them!
@@richardholdener1727 just for tits & pickles,,i think ive asked before,,theres a diesel,down in brazil,better than any you produce in u.s.,depending what you want..its a german MWM,4.2tdi.fitted to super duty & silverado,s..i have one here in aus.2002.s/d.,comes with no computer,no glow plugs,3 valvas,3" system,ohc,5sp.zf..std puts out 510 nm,140 kw..not much,but,reliable as a rock & tows 4.5t..turbo is mitsubishi,td04..i fitted a bearing,td06 ish,now with no other mods,has 700nm,170 kw..they twin turbo these in brazil,& do 200 ks hr.4500 revs.in a 4t truck..will fit any ford chev dodge truck.all mechanical timing.most people here that have one wont sell it..i still get about 12.5 lt 100..
Stock LS3 intake manifold is impressive.
Always liked the loom of the Edelbrock X-Ram.
It is pretty sexy.
It reminds me of the engine bay of a Ferrari
Looks like the answer is "Stock LS3"!
For street motors yes. Drag racers launching at 5000 will go with the shiny stuff
GPI has shown they can pick up 12 hp by porting/rod modding them.
@@C6Z_Bob I am pretty sure that is also throughout the entire curve, with larger gains midrange. I am hoping to order mine in the next couple of months. Ryan at GPI did an incredible job on my tune.
Richard, it's amazing how much you're helping the average driveway hot rodder make power, save money, andmake educated decisions. This video is awesome. I had a knot in my stomach watching the mid ram dual quad intake run hoping nothing went horribly wrong with the fuel dripping out of the rail... Keep up the awesome videos, and thank you.
Holy cow Richard, you're a BEAST !! Thank you for educating us !
Hands down the most informative videos. Thank you for doing all these test to shut people up. The dyno don't lie!! Great stuff, thanks again.
Ahmad
As usual you impress with the ultimate shootout of intakes(LS3), my hats off to you, keep up the Good work...
What a tremendous amount of work. Thank you so much for sharing this!!!
Absolutely awesome video with real empirical data that will save folks tons of money. This page is easily one of my favorite. Keep it up.
GREAT VIDEO Richard, hats off to you and the awesome effort you put into these videos for us LS nuts 👍🏻
Don't let this go to your head but, your channel is my new favorite. Keep it up.
Thank you Richard for these videos, I know it takes time to go back and overlay them etc. they are filled with lots of knowledge for beginners and experts. They have always been great content, but even better during a quarantine lol.
For the price, for all street applications, just run the factory intake, it makes power where you can and will use it most
Touch of Gray ikr, some of my friends look at me like im crazy when i say the stock intake makes more power than a Fast or sheetmetal one(expensive shiny part has to make more power right). And just like with cams, every intake is a turbo intake
You are 100% correct!
But... but.... but....
But when does power matter below 5000rpm IF you're racing?
Skunk Workz Garage hence why this guy said streetcars, and the stock intake made power all the way to 6,500. Also boost can help carry the curve out to over 7,500 if desired
this is the kind of testing I love to see. Apples to Apples, everything the same with minimal, if not only a single data point changed as the main crux of the test. I'm impressed at how good the stock LS3 manifold is.
I'm a dyed in the wool ford guy but still very much appreciate your LS videos. Physics don't give a crap about brands...
I own a GT500... and after years of struggling on what performance direction to take it, the cheapest and easiest way is to buy a used C6 Corvette and build the LS3. lol
What a great video, you must be a master @ swapping intakes now!
Love your videos! Thanks for all your testing 👍
Badass video!! It puts things in perspective for the LS3 manifold. A shut door case!!! Thanks for that - look forward to the 416 ci LS3 with carburetor.
Seriously surprised with these results
Good stuff Richard/Hot Rod! I'd love to see head and intake testing with the LS7!
i've run a few
Wow, exhaustive and thorough. Thanks
Wow amazing test, Richard! I am shocked and amazed by the stock LS3 intake. Personally I will choose the Kegalodon!
Go Keggie!
Sick intake! I want one! lol. Can you see that sticking out the hood of '50 chevy sheet metal tears and all. SWEEEET!!
Thanks for all the hard work you do it's a lot of good information looks like the across is a good all-purpose
Great video and surprised by some of the results. If schedule allows, would be real interested in your testing results on the LFX engine, the 60 degree V6 duel overhead cam engine. I'm now subscribed.
Sick man this is awesome I can’t wait to have my engine Edelbrock cross Ram engine running
Love your videos Richard no BS and just results! Thanks
This video and the others I've watched all make perfect sense. Thank you for all the hard work and straight-up factual numbers! I subscribed several videos ago and I still have more to watch.
To me, with long-tube headers, it makes more sense to run longer intake runners to balance the airflow. Is there a cross-ram where the TBs are hanging out over the valve covers, making them very long intake runners? It could possibly raise the torque numbers white a bit, and for a truck that's used like a truck, that's what is needed more than high-RPM HP numbers.
Great Work!
Amazing video
It is amazing just how well designed the LS3 intake manifold is. GM really did their R&D homework.
agreed
Richard, you're a Beast, Sir. 👍🤘
Always delivering the goods no matter what. 👌😎👍
Keep up the fight.✊
Who in the hell would want to lose power from an entire torque curve all the way to 6 grand, just to get a couple more ponies at 6700 RPMs
Love the content! I Run the Tbss intake on my Firebird its ugly but when combined with boost is an animal! This video convinces me to keep it 😎
Can’t wait to see the cathedral port intake test
I love these videos man. I would love to see you guys get your own show on motor trend.
The reason they make the ls3 to cathedral port adapters is so that you can throw a LSA blower on a 5.3 or older 6.0. For a while, you could get used LSA blowers for cheap just needing the coupler replaced/upgraded. I was buying the blowers from a local dealer for $300 each, fixing them for $100 or less.
Awesome video, thank you for the information! Would you expect the Holly 300-132 mid-rise manifold to perform similarly to the other two? I'm kind of disappointed I'll be giving up so much usable power/torque but I already have a TBI system on the car...
Can’t like this video enough. Looking forward to more.
Great info Richard! Factory manifolds are dirt cheap too @ the junkyard..
I'm new to the ls engines here in the uk for my race car. Awesome video very informative for my build
Looking forward to seeing the carbon fiber intake i was actually looking into buying one
Badass test. Thank you!
I know this is a little late but I was thinking about other intakes to try and then remembered the ALIEN intake from Tom Nelson. A DUEL FUEL Intake. Wilson, Hogan, Other sheet metal intakes. Perferrably LS3 type rec port. keep up the good work.
Killed it. Best vid ever
Love your videos. Thanks i learn so much
Glad to hear it!
Wow, this is awesome! 👍
Side note: I wonder how that Holley mid-rise intake would perform, with some velocity stacks on top.
Hey Richard, on the Holley Mid Rise Manifold the fuel rail seems to be leaking pretty good? just an observation but your videos and tests are fricken awesome keep it up
Hi Richard, good work. I see Texas speed has released their new LS/LT series manifold. The Titan SR-3 intake manifold has optioned intercooler block for the manifold. This manifold would be a great test subject? Cheers, keep up the good work.
You was more than helpful i have a original intake and was really thinking about got with the Hi ram intake but 👎 I believe I can make up on the big end with boost
Fantastic video! I wish y'all had an real time adjustable runner length choice. Mazda did it on the MX-5 years ago. Simply flips a door from one runner length to the next length using a vacuum based actuator. It would be neat if someone could make one for the LS3 and you could test it. Makes me wonder how effective it is.
Awsome results thanks for sharing 👍😀 greeting from Puerto Rico 🇵🇷👍
~~~》 The duel intake was screaming for twin turbos....
Great video.
Yes it was!
Please run some twins on that duel intake manifold. Would it flow some serious airflow, hp ?
Thanks
Awesome content!!! Thank you!!!!
Fantastic video mate, keep up the amazing work.
Would be keen to see a video of ITB's where you just try extremely unrealistically straight long runners and compare the change every 100mm of length.
It's not practical, but more of a curiosity factor.
Given it's just a lid change, my only guess as to the high ram variation is possibly from a straighter air path to the back of the valve.
I did that with my Hemi and many others
THANKS RICH !! BEEN TRYING TO DECIDE ON WHAT INTAKE FOR MY LQ9 BUILD THIS REALLY HELPED ME DECIDE HAVE TO GET THE SPACERS TO CONVERT IT TO CATHEDERAL PORT HEADS I HAVE !!
Most of these intakes come in a cathedral port design
Great video Richard.
I was hoping to see the carbon ptr.
Can you test those exact same intakes on the 416 also?
Thanks Rich, great clip as always. So here is a challenge for you regarding LS manifolds. Surely there exists a manifold that has dual intake lengths controlled via butterfly valves that can closely match the best performance of the stock manifold below 6000 rpm, then switch to a short runner length to get the above 6000 rpm horsepower increases. The win / win manifold. Once you find the best then add big turbo boost!
I made several adjustable ones-but nothing switchable
I would love to see the numbers on a factory "rod modded" intake available from shops like Rick Crawford Racing and Blue Line Performance.
It’s all about cylinder and valve size. This is why the stock intake is usually best or close to it on stock displacement/heads.
Thanks for saving me $800 and lessened power below 6k RPM. Your Awesome Richard!
Love it, but can we see some dual plane intake manifolds too? Thank you!
Great video.
Would like to see a test with the Holley cross ram manifold and a Speedmaster ITB cross ram manifold.......
What about the ls3 intake on a cathedral port with adapters..pros/cons/benefits/
It would be interesting to see how each intake would perform with a turbo setup.
Speedmaster actually makes something that made me look twice! Alas, they failed to make power. I am looking at the picture and wondering if there is enough clearance for me to machine longer runners? Without seeing one in person, it is hard to tell if the configuration has them running into each other dooming them to short runner length? Hey, GREAT video!!!
Badass. Thanks for doing this video.
@GwatneyPerformance stock LS3 rod mod $250 / porting $125 / heat shield $75. Take your stock LS3 intake to the next level affordability and compete with those peak competitors power numbers. They also offer stock LS3 throttle body porting $125. Neither mod tuning! Combined intake+throttle body combo power increase of 13hp-17hp (double these increases if your cammed!).
Don't fall for the hype
Good video cant wait to see pt2. Kinda surprised gm never made a variable length intake, but why would you with results like that
Hey Richard.. Thanks for all the great videos!! What’s your thoughts on the LS3 CID Efi intake 4.0 4500? I’m thinking about running it on my 6.0 LS with some nitrous.
Also do you have any recommendations on a efi throttle body?
Amazing video thank you!
Thanks for the info !
When is this "cathedral port " video coming out? I'll buy you a shot of "water".
Dang.... 19 manifold changes.
Richard if you ever do this with 19 BBC intakes, let me know in advance. I'll have to buy stock in Permatex lol. Good stuff man.
Just wounding if you had a fan in front of the engine that say run up to about 120 miles a hour would it change the power any
great job
Great vid
TOOOON of work !
So much
Richard Holdener
Although I’ve been a gear head all my life. Owned a 1200 hp V6 Buick Stage 2, and thought I knew a lot...
I’ve learned a ton by watching your comprehensive videos.
Thanks
What an unexpected suprise
Very informative video Richard. Learned a lot! BUT I would like your thoughts on testing a CNC ported OE LS3 manifold. This is becoming quite popular but I would appreciate your views on this practice.
they don't CNC port them-its done by hand, right?
I was hoping to see how well the stock manifold did on a larger displacement motor. I am currently rebuilding the LS3 for my 2010 Camaro into a 429 stroker.
You will see in the carb video
Great stuff 👍
That crossram is just BEGGING for a TT build...
Also highest average TQ and HP even more interesting!
I would like to see how the Holley Sniper Dual Plenum compares to the Edelbrock Cross ram. Similar designs and about a third less cost.
I remember reading this a few years ago and ls1 longer....anything newer that has came out since these tests that you like better?
I wonder what the new LSXRT FAST 102mm LS3 L92 intake stacks up against the LS3 stock intake manifold. Part number is 146105B. I wonder how much taller it is compared to the original FAST LS3 102mm or stocker.😮
Richard really enjoying watching your videos. I was thinking about doing a little intake testing myself by swapping intakes on my SBC 383 from my modified Lingenfelter SuperRam to the TPIS MiniRam short runner intake. I've ran both manifolds with my 700r4 and the SuperRam was more fun to drive and just a bit quicker, I've swapped in a T56 and wanted to test the MiniRam intake with the 6 spd. Your testing makes it hard to justify all the work involved in the swap, still might do it anyway. Keep up the great videos!!
I ran all of the TPI intakes back in the day
@@richardholdener1727 I've been messing with my 87' Firebird since 1989. I've read just about everything I could find on intakes, back before the LS motors came out. I've ported my SuperRam base and runners also siamesed the runners about an 1". My best 1/4 with the auto is 11.68@116 with the SR. I'm looking forward to getting back to the track and seeing how well I can do with the 6spd. The MR intake is a nice piece and I went 11.74@116, and if the stealth ram would fit under my hood I'd have one. It would probably be the best of the three for street/strip combination. I really want a torqstorm after watching your 80's test with the 5.0's, but I think my compression is just a bit to high. Bummer! Keep up the good work! 👍
Awesome Vid, I’m keen to see results with a cammed 416 using a ported LS3 manifold vs the LSXR 102 both 102 throttle body’s
Ok, ok, ok. Fantastic video as always. But what about with nitrous or under boost? I mean that's what most of us are aspiring for anyway right?
Great video
Richard! What do you think of the ported Ls3 intake/ “rod mods” that people are selling? In a n/a application with a cam like this, what do you think it would be worth?
The edelbrock x ram would be great for some twin turbo stuff. I wonder if you can put intercoolers in the edelbrock x ram manifold as well.
So good!!!
crazy how badass the stock intake does!
Richard or anyone! Help, would the ls3 intake fit ls4 engine? What is needed? Thanks fellas
Another home run Rich
Does the stock manifold have a known boost pressure limit? (Eg. Its been known to crack at 35psi) any advantage to metal over plastic? I know the holley has the ability to run an a2w intercooler in it.
Seeing how much better the LS3/Truck manifolds do vs LS2, I'd be curious how the LS3/Truck does on a cathedral port w/adapter.
Now do a header test on that LS3 mule. 1 3/4", 1 7/8", stepped and tri-Y
Someone else already did this test go check it out on TH-cam the difference was minimal no matter what they tried stock manifold a shorty length manifold and long tube manifold only the long tube had a gain of torque throughout the band The rest were bout all the same
