I LOVE that you guys actually went to the proper RPM to realize the gains of the shorter runner intakes. There are so many videos out there with guys complaining about losing power on a short runner intake and they shut the thing down at 6800.
Great info guys. I get so tired of videos that are little more than a hidden commercial for one brand or another when all I need is the data. Thanks, well done.
A intake manifold with a pulley seems to make the most power for some reason
:v
I’m going to go put a pulley on mine now let you know how it works 🤣
💯🤣😂
😉🙃
I have a ls1 corvette with a 600 lift cam. What pulley would you recommend
I’m looking for bang for buck
Thank you for the incredible amount of time and effort you put into this video. Amazingly informative.
Absolutely. It's what we love to do. Glad to see people find it helpful as well!
Thank you Guys great information . I have bought LS3 manifold going too work on it today . That was a great result especially staying street car with no hood issues .
Looked up your GPI Camshafts real nice I like SS3.
I see you were at Jims Shop .
Only dealt with him couple times great man indeed . R.I.P. Jim
Thanks for doing this guys, this is an awesome resource to have!
I’m proud of y’all !
Really enjoy the education!
This is a must save video! 👍🏾
Congratulations Ryan, you have came along way from the old 65 with three on the tree. Just remember all the fun we used to have on the levee with our old junk. GPI has a real good tech man in you, and hope to see you with a project of mine soon.
He speaks of the old levee days often...
Guy on the right looks thrilled to be making this video
Satisfied customer over here! I called asking about your LS3 Ported Manifold w/rod mod. I was told that would be a great choice for my 232/240 .626/.626 "baby" cam. Professional and friendly service....I'll be looking for heads soon. Thank you for the hard work on this video. Keep it up!
This was super helpful! Thanks guys. My camaro is a street car so looking at your ported manifold!
I don’t even own a fucking Chevy and I watched this whole video like I was studying for a test. Great video guys
Same here :)
Thanks for doing this test. My LOD is going on next month!
Where you buy it
A lot of good information. This is helping me understand getting into LS and what to expect figuring out a swap combo.
Glad we could help!
Absolutely a great video guys!
This is a well done, and much appreciate video.
So interesting video ! Thanks a lot, i will follow you from France!
This was a REALLY GOOD video. Thanks guys
Man I really appreciate this test yall. I'm building a 416 and want to use that CID and a 4500. Thanks for doing this to show us Garage Warriors what works and what don't.
Did you finish that build I’m currently doing the same setup but also have the hi ram 102 option on the side
@@Day1dj5oh nope. Sold everything.
Wow a ton of work . Thanks guys
Thanks!
Been looking for a NA combo. Thanks for the info. I will be putting a 14:1 SBE except pistons.
Awesome comparison. Now just imagine. In maybe 10 years these same guys will be doing the same thing only with all electric set ups. 3000hp with two 9 volts and jumper cables. Cant wait.
Depends on cubes too shaferoff has a 454 cid with the mast intake that makes 760 hp at 6500 rpms
Super impressed guys. thanks for a great video. With ported LS3 heads, I was thinking about match porting the last couple inches of the stock LS3 intake to the new cnc inake port. (not a factory CNC) I learned from you guys to leave that LS3 intake in there! not ready yet for a full inake port setup, would the match port help at all?? many thanks, Jeff
Great video. Learned a lot. Thank you.
Thanks!
I have a carbed ls3 with prosystems carb and a cammotion street king cam. I’ll be calling soon. Gonna switch back to plastic intake and ss4 cam
It would’ve been interesting to see the stock one vs ported in the 3500-6500 rpm range
Thank you. I am looking at your Max Performance Package for my 10 SS2. It is auto, so i need to do the LS3 conversion as well.
You know the funny thing is that I did the same thing for John on the Cleveland heads and intake, which I did the design work on, I spent countless hours and plenty of my own money finding out what was best, the investment is huge when you are putting your own money into this stuff. And then the customer wants to pay nothing for it. I commend you for what you have done. Now people will rush off to an engine assembler and tell them what parts to buy and act like a HERO when the engine makes power. I think you understand what I am saying. Great work, Johns intake is awesome. I only wish you would have ran the Cadalic SUV intake???
R&D work never seems to payoff like it should from a money-effort standpoint.
Did it for 10 years. Funded mostly by one customer.
The doubters come from everywhere.
You could have correlating numbers from the flow bench showing improvement.
Then the nay sayers would come out of the woodworks saying,” air flow isn’t everything, the dyno will tell the tale!”
Get it on the dyno and sure enough the tell was told.
Then here they come again,”But you can’t race a dyno, only the track will tell the tale!”
Car goes down the track consistently faster and it would all go back to the “airflow isn’t everything narrative.”
The most frustrating part of life is when the power wasn’t what was expected.
They all came running for the flow bench data first.
Never a straight up, you did a good job and you’re headed in the right direction. Just doubt, doubt and more doubt.
excellent video...thanks!
Man great video!
OMG THAT CREAKY CHAIR!!!!
The stock or modified LS3 and the higher Version of the Holley sniper are hard to beat value for money.
This is excellent. Wish I could fit the X1 in my Trans Am without hacking it to hell. Have the FAST Medium Runners now...
9:45 boy did I use to be that guy. If the number was bigger that’s what I wanted lol glad I learned a thing or 2 in the long run.
Would y’all do the SS4 with the Holley mid ram??
What the size of the cam is that you put in on the second run?? What kind of cam??
I'd really be curious to see the entire curves. It's nice that you're considering average power 5K+ but I don't feel like that's the whole story.
Is there any room for improvement on my 2011 5.3 until I can get cam and dod delete and maybe vvt delete. Thinking about the 90mm tb or should I go bigger
I'm glad to see the son in law from Sons of Guns in a new career...😂😂😂
Great video
Do a comparison between Holley sniper efi vs Fitech I really want to know about tuning issues with fitech
It's the exact same manifold. Sniper, fitech, jegs, ebay special, etc.
All of those fabricated aluminum manifolds are sourced from the same Chinese manufacturer.
I got a hold of your intake ls3 rodmod what cam and stall works well with a automatic transmission stock the one that comes with the car it’s an 08 base c6 I plan on running it on the street
So the ported Ls3 manifold and stock TB is pretty much the best combo? Not sure if i got that right?
Does the gpi ported rod mod ls3 intake use the stock throttlebody... can it be used on my l99. Thanks
Please test the new Fast LSXHR. Pretty please
2014 Camaro 2SS L99. K&N C.A.I., BBK shorty tune length headers, VRam wedge on the throttle body, x-pipe and muffler delete on 93 octane in FL. This a daily driver that I want a bit more out of. I do plan on buying your SS1 cam. The car has 71,000 miles on it. Will any of these manifolds help the car?
I’m looking for an intake upgrade for my 2004 Chevy Tahoe 5.3 Ls3 what is your recommendation?
Bro ryan look totally different compared to now💪🏾💪🏾
I see Performance Design displayed a new LS3 intake at MPMC. I hope you have an opportunity to compare it as well.
Cliff notes? Any hp gains on otherwise stock motors?
Frankenstein ED is coming out with a 4500 intake sorta. It looks like it would be interesting to see how well it would do.
What intake would you guys recommend for a ls1 corvette??? 600 lift cam
Can’t wait! I’m looking at 2015 Camaro SS’s with the ls3 with 6 speed mt as they are my absolute favorite 5 gens. The tail lights and front end are the best looking out of the 5th gens and even better looking than the 2019+. I’m coming straight to you guys and getting 13:1 cp pistons with ss4 cams beehive springs and light weight valves rockers and chromoly rods 8 pound fly wheel. Also sending you my heads to be cnc port and polished. As well as an intake manifold. Going to call ARH and see if they will do a set of equal length long tube headers as well as equal length exhaust with only high density magna flow resonators and x pipe. I want to be spinning 7500 rpm’s. At my dad gas station he carries Sunoco SS100 octane fuel so 13:1 shouldn’t be a problem.
I agree, I like the 14-15 Camaro the best myself. The tail lights are similar to a 69. I have a 2015 LS3 6 speed manual 1SS and I am looking to buy a 2015 2SS 1LE when I find one that I like.
I have a 2015 2SS RS with the TR6060 and love it, you will need to upgrade the axles and diff with those engine upgrades, they are the weak point of 5th gens.
Seems like unless you have an aircraft carrier boat anchor for a right foot, you're better off tinkling with a factory air intake
* however...it is fun to just drop anchor every now and then :)
Looking something for my LS4 what do you suggest?
the rod mod intake you can thank rick Crawford for coming up with that idea...
Thanks rick Crawford
On the CID intake I would've liked to have seen a Wilson the CID intake topped off with a Wilson Manifold's elbow and a Wilson's Manifold 105 Throttle Body I think that would be a pretty good match
4500 flange version with a good TB would be identical to a 102/105 and elbow.
I’m still debating if a TBSS or a Holley high ram would be best for my LS mustang gt. TBSS should be fine but that high ram is just so damn good looking.
Definitely go with the TBSS. Hi ram will kill lots of low end torque/power and not make enough more power then the TBSS for its use to reasonably be justified.
LOD with Twin 94mm Precisions please...
Do IT with the LT1 🙏
Is this 416 ci or 376?
Stock ported manifold with the 102 tb?
You guys should test the Trinity
What are the best brands of the Yukon XL 2019 to increase the torque or horses. Thank you
Easy, don't buy a 2019 anything.
Looking at your dyno graph between the hi ram and the LOD, the hi ram out performs it across the entire curve. To me, the LOD is the lesser manifold unless you’re trying to be a HP king. I’m gonna love running into someone running that LOD.
How about a hi ram lower with dual overhead throttle bodies vs CID?🤔
Theses two girls spend a lot of valuable time together 😂
Remind me again who makes that dyno console...
I would like to find the cross ram dyno test on the LS motor, which had the highest average torque and horsepower below 6,000 rpm. I saw the test apx. a year to two years ago. Anybody know of this, let me have the url. Thanks

Good morning
I have a 6.2 gen IV ls3 engine
According to the mechanic with stock intake engine is pushing 550hp with stage 3 cam
I want to replace the intake
What intake do you recommend me with the fuel rails ? Thanks
Depends on RPM range, hard to beat a ported stock intake up to 7K RPM....
Maybe 10 min of info, that was some great stuff-minus no IAT1s/2s, AFR and any info about tuning differences/how much did they alter the tune and where and what changed bet manis, and what were the two cams specs?-All wouldve been great to make it to 20 or 30 min depending on tuning diff info..
And What heads and cubic inch?(oh pistons only, I remember now) -What did compression end up at?
In the amount of time it took you to write this "comment" you could have clicked the link to the written article and all your questions would have been answered.
Why not test the Fast LSXHR 103?
How about a hi ram with 4150 throttle bodies vs CID with single 4500?
Kyle Milligan a CID with a dominator is what i wanted to see
Is the Holley sniper better then stock ls3 intake?
gave 5mins worth of info took 30mins good job

You need a 102TB to make the Fast work bottom line. I have heads, cam full exhaust..this is my last mod before i change the cubes. But cars on the dyno seem to see little gains..
I legit gained nothing with my 102, I even smoothed the trumpets getting rid all flashing. It followed my ls3 hp and torque lines. Will see what happens when I stroke it!
@@dailydrivenmuscle. which version of runners? What cam spec?
@@paisley2342 long runners and 235/243 .624 lift, I'm going to change the cam and run longer exahust duration and change the LSA to 112
No Trailblazer SS intake?
So this stock Ls3 with only pistons 10:5 compression a huge hydraulic cam and a cid 4500 make 700 hp ?
Yup!...LS ENGINES ARE AWESOME!!!...FORD AND DODGE DONT HAVE AN ANSWER
@@nathanielbolden5053 thank you when ls 1st came it the conthrport motors was the only motor between Ford dodge Chevy to make 1 hp per cubic inche speed up to ls3 square ports motors it doubles hp per cubic inche
@@god1st.530 LS3 is a 376ci, 376 time 2 is 752..... no stock Chevy engine makes 752hp(thats 2 more than a brand new 2019 ZR1 supercharged engine makes). although i agree that ls1 made 345hp/350tq with 346ci in 1997 and 350hp/365tq in 2001 due to better intake
@@Shadow0fd3ath24 I've own 7 3-5th gens Camaros since my 1st 85 z28 at age 15 an I have the fastest true stock suspension on 28 tire car in the south region areas. An ls3 with heads cam tune can make from 500-700 hp all day. If a ls1 controport head cam motor can make 500 hp by mistake an ls3 can give you some shocking hp numbers also. The supercharger Corvette use a small displacement motor with help of force induction no good after market cam nore high dollar heads but just a tame version the Corvette makes 650 an plus turn down so it's not hard to get any ls based motor to make higher hp per mods or cubic inches
@@Shadow0fd3ath24 The LT5 made about 350+ from 350ci in the late 1980s.. Look at the wheel hp those cars make. Its prob well higher than that.
GPI FTW
How is power below 4500.. ill be keeping my stock ls manifold, i could add 1psi boost and gain more than 10hp.. if it gained all across the board then it might be worth it.
Just curious why you are running your tests at 140 degree when the thermostat starts to open at 180 degrees and the fans come on around 217 degrees??
Parameter optimization in the dyno cell. Engines make better power when the water is cooler.
@@rustysausage69 huh.
Buick ran their turbo v6 Indy car Engines at 200 degrees Fahrenheit for more efficient combustion...
PhillLsx Ga. Thats groundbreaking news, i guess every controlled environment engine dyno shop in the US is doing it wrong. Id like your source on that info if you have one.
@@rustysausage69 directly from a GM proving ground engineer.
He has a 10 second factory Crank rods block and piston regal T type.
Gm runs their vehicles hotter for more efficient combustion.
The cooling fans in my trans am coming on low speed around 220 degrees Fahrenheit on the tech 2...
What about the edlebrock cross-ram intake? It has two TBs
www.hotrod.com/articles/giant-ls3-intake-manifold-dyno-shootout/
Expensive and not as good as the FAST LSXR, better than the stock LS3 intake.
FAST LSXHR would do great in this too
Nearly identical to the LSXR, yup.
Yeah, it's nice to not have your dinner plate shook off the table, by a engine on the dyno! Ha-ha, I'd open the window so I could hear it better!
I can’t find the lod speedworks manifold nowhere
Holdener just posted a 427 comparison between stock ls3 and ported rod mod showing no gain. Plenty of contradictory info in the last decade, and I like my RCR intake. Hope it doesn't affect your sales.
Actually it did gain, just not as much as he "thought it would".
Also, they put it on a very poor combination for a plastic intake, a 427 needs some lungs, not LS3 heads and plastic intake!
Really want to see some LS7 intakes. Need stock vs msd vs sniper
I'd like to see all the LS7 composite intakes vs. LSX/LS7 4-barrel aluminum intakes.
What about testing a MSD massairforce
MSD doesn't make an airforce for rectangle port LS3 style heads.
When we get a chance to continue our testing on the LS7 platform, we will be testing the MSD!
Sweet. I have an MSD for my LS1 havent put on yet cause i want to get headers and ypipe from Texas Speed, already have catback
no BTR intake?
What size cam was used?
I believe it was our SS4 or something close. Like a mid 230 at .050 intake duration cam.
I would rather see the power and torque curve charts than just the top power and torque .
I agree
Pretty sure they have it on their website.
I mean it’s on their website clearly you didn’t bother even checking
@@FredRTP96 I talking about the video I'm not on there webs.this is a TH-cam comment.
How can you find the lod
Look in the trash can.......
so which had the biggest power gains???
CID
I think you guys should get together with BTR a bit and throw some ideas at each other
Lose the egos and see what ideas could work also
We are good friends with Brian and the team! They do great work. We just both stay very busy, and with the business being so far apart - it doesn't make collaborations easy!
No msd?
Msd intake is trash
Not available for LS3 rectangle port head, only for LS7 or cathedral port.
Hey guys..
Great video👌🏼👌🏼
I'm in Aus.. I run an ls3 in my car..this year looking to do a power upgrade. really informative.
Do u have an e mail I can contact u on??
Cheers🍻
Scott
Hey mate i'm in aus too, what sort of power upgrades were you looking at getting and how much you wanna spend?
I don't have an LS3 but i do have an L77 that has got over 400kw and 700nm torque!
I might be able to help with anything you would like to know?
no MSD Atomic manifold?
Omega Doom I believe that it was discontinued a few years ago.
Msd is for the ls7 I believe
Air force isn't available for a rectangle port LS3 head, only for LS7 and Cathedral port
Wuts the deal with rod mod .can u just clean it up and not put rods
Biggest gain is the radius rods.
