He works ALOT...maybe not hard. Work smart & hard....as he does. He is saving most of us LS guys considerable time, money, guesswork!!!! Keep it up!!!! We need facts, not bs.... Richard gives FACTS........ I APPRECIATE HIS INFO...ALOT!! DYNOs don't lie....totally objective....👍
Richard, I really appreciate all the research you are doing for us LS guys. I'm sure you are saving people a ton of money, on finding out what combination are good for them. Instead of wasting time, money and labor on trial and error!
The thing to remember is that the flow characteristics of this test are the same for ever single engine produced. They are all air pumps, this isn't just an LS intake test, or even just Chevy. This is all engines intake testing. Its the same protocol we have seen since dyno testing began. We know a certain runner length, volume, and velocity will produce peak power in a given rpm range for a specific set of engine parameters. The part that has forever confused me is why major manufacturers for decades discarded all this information and built pure junk motors knowing they could do better.
Great test. I'd like to see a gen3 hemi intake manifold test. As in a early truck manifold vs. 6.4 set manifold vs factory 6.1 vs Edelbrock efi, vs 5.7 car intake.
Yea man, this is exactly the type of content I’ve been waiting on. Informative, comparisons. And you still show the builds from start to finish. I’m picking up what your throwing down. I’m glad this is free, but even if it wasn’t I’d still pay for your expertise. Your knowledge is invaluable. Thanks.
I know that some of these tests are repeated but you keep trying to beat the information into our brains. Long runner=street. Short runner=race. Boost=better. Keep up the good work. I would love to see a 4.8 or 5.3 ultimate N/A tow build. Best low end torque cams, heads, intake(probably truck intake or tbss), and headers.
Camaro Rick : yah, 24.12, not 668 hp lol. typo city. But its not what he typed its what he said in the curves at 568 hp by the five point summary at 8.49. LOL and behoLOLden. But we are sure getting a great picture. Such an amazing test Richard H. MASSIVE ATTACK SKILLZ..
Wow I'm currently running a cheap ebay fabricated intake and was going to upgrade to a holley high ram due to the other mods I have but being a street driver I'm really considering going a dual plane with a 4150 now, this has opened my eyes to a whole different level
My brother and I have been subbed for about a year and this whole channel is what was the best part of any car magazine. Currently having a 900+hp Evo 8 I got brand new off the showroom in '03, him with a turbo '10 Camaro SS and us both with matching '04 CTS-Vs, I love that this channel isn't biased between imports and domestics just like him and I.
Area under the torque curve is the true judge of a good intake. The FAST LSXR is awesome - over 450 lbf.-ft. from 3700 all the way to 6900, normally aspirated. And the engine is readily available at a reasonable price in every junkyard. We live in awesome times for hot rodding.
🤨 Soooooo . . . Factory Plastic Intakes still Kings ? That's my take here.🤔 Aftermarket metal intake only if running mid-high boost levels as a safety net. 👌🏻👍🏻 Thanks for running these exhaustive tests and weeding the hacks from the facts.
Thank you. I was thinking about putting a TBSS manifold on the slightly modified 5.3 in my truck but if it only added 14 hp and 16 pound feet of torque in this bigger engine with a bigger cam I’m sure it would add even less in mine and it wouldn’t be worth it.
A long long long time ago when I put together my first LS motor heads/ cam/ Nitrous setup. I went with the Aluminum Weiand Lingfelter Signature series for many reasons. Some more things to consider besides the power. - Price. Because of the "heat soak" rumors and the fact that the FAST intakes were the preferred monkey see monkey do back in those days these aluminum intakes got a bad rap. So you use to be able to pick these up used cheaper than you could a LS6 intake or the same $300-$350 price range. The Fast intakes were always way out of my price range starting out. It really didn't make sense to me to pay over $1,000 for my set up. - The aluminum intakes had some advantages instead of the heat soak rumors people went with because they were stuck on the composite FAST intakes. Mine came with a window for porting I purchased it used from a speed shop and they ported it for me. I was also terrified of having a nitrous backfire on the FAST composite intake and blowing up $1000 just like that. I did have a nitrous backfire with the Weiand and that window blew out and saved both the intake and the motor. - Draw backs were it was heavy.... Didnt seal easy and always was a little bit more difficult to seat than a normal composite intake. It also used gaskets instead of o rings which help complicate the issue. Overall for the money it was a great value and I think it was the right choice. Car ran great and beat many cars with FAST intakes and similar mods. Would love to see a test with some pocket port work done on one to see if it comes anywhere near close to the FAST
damn, never thought of the nitro causing a frag grenade effect with a weaker composite material, but it makes sense that the aluminum is able to hold down the backfire vs blowing up your money basically XD . so from what i read, if you want room to upgrade and have peace of mind for reliability, go with a hunk of metal and have the headache now vs later XD. Thanks for sharing this great little tid bit of experience!
Thank you for your investigative LS work. In my 72 Nova sits a very well built 385ci gen 1. Almost 500hp on dyno with performer rpm. Spinning 26×10 drag radials at the track got old fast. Went to a Weiand Team G single plane and rolled the fenders again for 28×10. Mickeys and problem solved and now noticable more power up high. The 6 liter and 4L80e in my work truck will be on notice when things go bad with the body rust-wise. I need 800 or more power! Twin turbos here l come if we keep our rights and keep working....
The LSXR-T manifold is for clearance concerning throttle placement in a truck. That is why GM made that style manifold. An LS1 would have conflicts and clearance issues. Look under the hood of a 99 or later truck and you'll understand.
Makes the decision easy. Fast 102's or MSD if you want to win races and have the budget for an aftermarket intake. Easy and real gains to be had on all intakes with simple intake to head runner port matching.
I think this was the best ever, very informative LS intake shoot out ever! Thank you so much, I always felt that my bbk ssi felt better then my ls6 and this comparison proved it.
You’re a godsend during all this boredom. Now that you have all of the intakes and required parts let’s see how all of the numbers would look on the typical 5.3 setup. Or at least just heavy hitters. I know there are other separate tests out there, but I like your style of running the exact same combo for all of them to remove most of the variables like cam, heads or compression differences. Keep up the great work, we all love it. And everyone needs to start hitting that like button, 60k views and 2k likes is sad. Don’t be lazy, Richard definitely wasn’t lol.
I know it was alot going on here. No complaints, I love your content. Just wanted to let you know at the end where you are showing the results from everything you mixed up the MSD and LSXRT Numbers. Keep up the great work.
Hi Richard, thank you for all of your hard work with this video. Can you please list the the Results 1-20, WITH THE PRICING/COST FOR THEM. Thxs a lot 👍.
A ton of time you spent on this! Thankyou! Could you please take a few mins to just overlay the curves for the top performing intakes? Like the TBLZERSS, FAST 102, Holley, etc. The bbk peak numbers looked amazing but I'd like to see the whole picture overlayed? Thanks so much for the time you spend on these!
So my LS build is a little bit of a mutt when it comes to parts. LR4 using a set of 4th gen connecting rods spent a bit of money to get a decent set of pistons (DSS Racing 3.785" Forgings meant for floating wrist pins) Summit Pro LS stage 2 low-lift truck cam kit int/exh (.523"/.524", 218/227 at .050", 112+2 LSA). It also comes with the required spring upgrade for the additional lift and duration at RPM. So I got a deal on a TBSS cathedral port intake, and honestly, I'm really happy that I got mine for about $110 fully dressed with injectors and fuel rails. Went on FB marketplace and found a dude selling LS1 cylinder heads for my 4.8for $120, hand-polished the combustion chambers to get rid of casting flash, and installed a set of stock-size Manley race series SS intake and exhaust valves (2.00" int/1.55" exh.) yes, it's a little strange, but I chose to follow the 'run what ya brought' mindset, so I think I'll be alright. Not looking to make the most power out there. I just wanted a decent combination that I could get on the cheap from the secondhand market. And anything I couldn't get from there I got something better than stock.
TBSS intake is probably best over all. That 497 torque isn't the highest but it's close. On the street if money is an issue, because lets face it, there are a lot of things you have to buy to make those other intakes work. Dorman makes a better looking intake that will make the same power as the TBSS for little cost. Thanks for the video. Great job 👍
Another great video! I seem to remember you mentioned on your rec port intake video that you had tested an LS3 intake on cathedral heads using adapters. Can we expect to see that in a future video?
Good to know! I’ve been looking at intakes for my 5.3 for awhile now and this just got me set for the LSXR intake to get. Healthy cam setup and exhaust is coming up next, intake will be right after!
Good stuff. Didn't know the TBSS manifold was so good. Typo at end of video for BBK. If it made 668 HP, that would be insane. Also, I think Fast Intakes aren't worth the $$$. I still want to see how much gains can be had from a pro ported and massaged stock LS manifold.
Most of what I take from this is if you spend 1k to run a carb on a ls that you could have kept the factory old style truck manifold and made almost the same power with a better curve. Or even more power and better curve if you have or swap to the tbss style intake
Just picked up a TBSS intake used and it's replacing the stock truck intake. Looking forward to the gains. Just gotta tune the thing and I'm good to go. Going with a LS3 90mm throttle body as well as the LS9 injectors
Great testing! Thanks for doing these comparisons Richard. There’s a typo at the end where the power numbers are detailed I think. The BBK intake spec says 100 hp too much. Simple typo I think.
For the money the Trailblazer SS is a great starting point as it comes with the salvaged engine assembly! Cam, headers and high flow air filter would make a nice street package. Thanks for all the great work and data!
the short of it. the fast lsxR is the best performing all around. the tbss is the best stock and cheap intake. unless you're draggi or running at full RPM constantly for some reason, ANY of the intakes are fine and it doesn't matter.
@@richardholdener1727 I remember seeing you said you had done it, was wonder if it was going to be thrown into this test. Do you think the spacers mess with the injector angle?
For the 5.3L LS (cathedral port) , The Holley Sniper 92mm Intake w/Fuel Rails and Crossover (P/N 820032-1) + 92mm Throttle Body (P/N 860004-1) is $863.00, and the 102mm FAST Manifold (P/N 146302B), 102mm Throttle Body (P/N 54106) + Fuel Rails (146032B-KIT) is $1,508.00. So check those $/HP figures wisely my friends.
Great video, unbelievable and hard to find this much info in one video, thank you I have a LS1 in a sand buggy been wanting to some additional mods and now I think its going to be the manifold, already have a cam and springs, rockers upgraded
A1auto offers a intake for 159$ and im seeing guys use it vs the dorman ls2 on builds I don't want to hype it up and they blow the price up but wonder how it compares to the dorman intake...
Wrecking yard motors won’t spin 8k and live for very long. Engines that spin 8-10k cost 20k and up. Then they aren’t good for street use because of the beating the valve train takes from the heavy springs required.
@@bcbloc02 SBE drag race record LS iron block guys are spinning 8000 rpm for a whole season. The RPM doesn't kill them, it actually is safer for them since they keep torque low at high RPM.
Way back when I had the same setup but stroker, I was the only one I knew of with stock LS6 intake. 1 3/4 to 17/8 stepped longtubes to a 3.5, not 4 inch, and nobody ever beat me
Just look at the runners and the platinum size and that would give you the results more or less compared to the rest..the over all winner will still be the fast 102 LSxr
Can you do a test for factory lsa supercharged engines and see the gains from ported runners vs nonported runners ? Like start with unported blower , port snout, port blower , port runners see what gainz are seen
Great test. The best intake is still the fast 102mm. The msd makes about 10hp more but is down in hp and torque through most of the rpm range compared to the fast. Fast 102 for the win on this combination.
@@richardholdener1727 you should try a ported fast 102 vs a ported MSD from Tony Mamo. These are the best ported versions you can get that actually get good gains from his strategic port work.
@richardholdener I'm just getting into the LS MOTORS. WHY dont you and others test stuff on the 6.2 LS PLATFORM 2ND question I wish youd do 1 test with a quadrojet old school carb
Keeping my tbss intake, going with a BTR stage 2 v2 truck cam in my little 4.8L. Gonna attempt to take advantage of the factory 243s and make good power! I’m planning to ditch these 3.23 gears in my 08’ single cab for some 3.73s or 4.10s and go from there! This will be my first build, everyone starts somewhere! This intake video just goes to show how well factory intakes can be especially the tbss! I believe the great equalizer boost could be in my future 👀
Hey Richard thanks for teaming up with kyle #goatropegarage. Your format and editing is just what we like. Some pics along with your words of wisdom is all we need.
so what I learned from this was... just run the stock truck manifold it comes with ( provided it fits under the hood) and spend your money on a terminator ECU. was seriously considering running a dual plane carb setup but in reality... I'd be spending more money to make less power. really wanted to see more out of the dual 4 setup but that was a huge let down. looks cool but thats about where the buck stops. thanks for doing these tests and sharing the info in such detail.
Man, this video is absolutely amazing! Your channel is one of the best on UA-cam in my opinion. It would be THE best, if there would be more Mopar bb stuff ;)
Have you ever done a duration vs lift LS cam test? How much power does a "low lift" .560 (cheap stock replacement valespring type cam) 220-225ish duration cam make vs a .600 lift 220-25 duration. Possibly going to the extremes of 200-210ish duration 600 lift cam and a 230 ish duration "low lift" cam. Mainly interested since most stock LS heads dont flow anymore at .600 than they do at .550.
Id like to see this test on the coyote motor. I hear the late model truck intakes proves to be better than lets say the boss 302 intake etc. Solid LS video i enjoyed it.
I was hoping to see the Dorman 3 piece truck intake tested...cool video...crazy how fast 5yrs fly's by since I 1st read this...still cool as hell..thanks!
O.K. Richard, thanks again for working you ASS off to educate me !! Runner length is key to tuning this stuff, (you've been telling us that forever !) Here's a test I would like to see...I have the same dyno you have,and the ECM wideband stuff on my Super Flow Dyno, the question is ...WTF? Most of the stuff I do is carbureted(approx 75-80%) I noticed that my AFR readings are sometimes far apart from each other. The one side will be nice and sweet mid to high 12's on AFR, but the other side will be sometimes 10 or 11:1, It seems that the dual plane stuff is worse, but sometimes even the single plane stuff does it.I've swapped jet sizes side to side, I've swapped sensors,and even swapped sensor cables side to side,and the readings still stay the same.(It's not the Dyno, or ECM Wideband system.) I've tried cutting the center divider on the dual planes and/or running a open spacer under the carb. that usually helps, but no always. I've noticed that the dual plane intakes with the center divider that goes to the top, never runs smoothly after 5500 ish,as well as losing power. thanks man , you're AWESOME !!!
@@richardholdener1727 .Thanks man! No I'm talking about most every engine I test, it seems as if the thing has a dual plane it's worse, but still dual planes are terrible !. I suspected the sensors/or sensor boxes,So I swapped sensor side to side, no change, then change sensor box side to side, still no help. Grrrr.. Thank you so much for all your hard work, I can't even imagine how much time you spend testing .
Do you think I would benefit much from going with a FAST LSXR intake over a ls6 intake with this setup? 5.7 LS1 (2000 Trans Am) with stock bottom end • HEADS: Stock 243's decked 20 thousandths • CAM: Comp cam 54-446-11 .595/.598 232/234 112LSA • INTAKE: Ls6 intake • INJECTORS: 60lb Deka • HEADERS: 1 7/8" Long Tubes with true duels out the back
I'd love to see water/meth port injection on a long-runner manifold. I'm guessing it'd need to be custom. The only bolt on I know of is Snow's port injection for the Holley Hi-Ram.
I love this video, because it told me everything I needed to know at the 2:20 mark. Looks like my old stock 5.3 is gonna keep the stock manifold until I muster up enough money to get some goodies internally. Haha thanks for the info guys!

Good stuff. Didn't know the TBSS manifold was so good. Typo at end of video for BBK. If it made 668 HP, that would be insane. Also, I think Fast Intakes aren't worth the $$$. I still want to see how much gains can be had from a pro ported and massaged stock LS manifold.
I cut open my TBSS to remove all the unnecessary crap, and also opened up the snout for an ls7 throttle body!
Id love to see it up against a fast
Agree!
Richard you're the best thanks for all the info and hard work
Thank you so much!! This has really helped me with making the decision on keeping the manifold I have or getting something different.
Most of what I take from this is if you spend 1k to run a carb on a ls that you could have kept the factory old style truck manifold and made almost the same power with a better curve. Or even more power and better curve if you have or swap to the tbss style intake
I'd like to see a ported intake shootout. Invite popular intake porters to show their worth and see if they are actually effective.
Everyone has already said it, but fantastic work once again Richard.
Cheers😊
Love this comparison. I would save my money and stick with the truck setup for my usage.
Just picked up a TBSS intake used and it's replacing the stock truck intake. Looking forward to the gains. Just gotta tune the thing and I'm good to go. Going with a LS3 90mm throttle body as well as the LS9 injectors
BBK results are a typo at the end. Really cool video.
Great testing! Thanks for doing these comparisons Richard.
There’s a typo at the end where the power numbers are detailed I think. The BBK intake spec says 100 hp too much. Simple typo I think.
For the money the Trailblazer SS is a great starting point as it comes with the salvaged engine assembly! Cam, headers and high flow air filter would make a nice street package. Thanks for all the great work and data!
the short of it. the fast lsxR is the best performing all around. the tbss is the best stock and cheap intake. unless you're draggi or running at full RPM constantly for some reason, ANY of the intakes are fine and it doesn't matter.
way to go, I am leaning to wards Trailblazer SS the Fast a second choice, thanks for the video
I'm still waiting to see the Ls3 with adapters on a cathedral port head, keep the test coming!
i did that test-its not good
@@richardholdener1727 I remember seeing you said you had done it, was wonder if it was going to be thrown into this test. Do you think the spacers mess with the injector angle?
For the 5.3L LS (cathedral port) , The Holley Sniper 92mm Intake w/Fuel Rails and Crossover (P/N 820032-1) + 92mm Throttle Body (P/N 860004-1) is $863.00, and the 102mm FAST Manifold (P/N 146302B), 102mm Throttle Body (P/N 54106) + Fuel Rails (146032B-KIT) is $1,508.00. So check those $/HP figures wisely my friends.
Great video, unbelievable and hard to find this much info in one video, thank you
I have a LS1 in a sand buggy been wanting to some additional mods and now I think its going to be the manifold, already have a cam and springs, rockers upgraded
Dam Richard you are a very hard working man.Thanks for all this great information.
Just found this channel, I love it. Answers questions we all want to know
A proper b2b comparison of how should i spend my stimulus
A1auto offers a intake for 159$ and im seeing guys use it vs the dorman ls2 on builds I don't want to hype it up and they blow the price up but wonder how it compares to the dorman intake...
Would you ever consider testing uber high rpm motors to show how much those intakes really help at the top like 8000 rpm+?
Wrecking yard motors won’t spin 8k and live for very long. Engines that spin 8-10k cost 20k and up. Then they aren’t good for street use because of the beating the valve train takes from the heavy springs required.
@@bcbloc02 SBE drag race record LS iron block guys are spinning 8000 rpm for a whole season. The RPM doesn't kill them, it actually is safer for them since they keep torque low at high RPM.
on your summary for the peak hp and tq, the BBK shows 668 hp instead of 568. anyways, good stuff!
Way back when I had the same setup but stroker, I was the only one I knew of with stock LS6 intake. 1 3/4 to 17/8 stepped longtubes to a 3.5, not 4 inch, and nobody ever beat me
Allways learning! Great vid!
Tbss, dorman, lsxr the best proven again 🤟
Can’t wait to see what you do with the 8.1
I’m really curious about the BTR Intake would be great if you test that one
Just look at the runners and the platinum size and that would give you the results more or less compared to the rest..the over all winner will still be the fast 102 LSxr
Wow ! Thanks Richard this was excellent!
Have you done a Victor Jr manifold running EFI comparison?? Might be a good idea
Can you do a test for factory lsa supercharged engines and see the gains from ported runners vs nonported runners ? Like start with unported blower , port snout, port blower , port runners see what gainz are seen
that would be good
Great test.
The best intake is still the fast 102mm.
The msd makes about 10hp more but is down in hp and torque through most of the rpm range compared to the fast.
Fast 102 for the win on this combination.
fast lsxr and MSD made identical peak power-592
@@richardholdener1727 you should try a ported fast 102 vs a ported MSD from Tony Mamo.
These are the best ported versions you can get that actually get good gains from his strategic port work.
Makes me feel a little better about my holley dual plane on my carb 5.3. Maybe Ill make it on your channel one day cuz we're both in california!
@richardholdener I'm just getting into the LS MOTORS. WHY dont you and others test stuff on the 6.2 LS PLATFORM 2ND question I wish youd do 1 test with a quadrojet old school carb
I have done a lot of tests with the 6.2L LS2-Q Jets work well-run them a lot
I read the article so many times I knew the results already lol. Was searching for the video. Good stuff :)
Keeping my tbss intake, going with a BTR stage 2 v2 truck cam in my little 4.8L. Gonna attempt to take advantage of the factory 243s and make good power! I’m planning to ditch these 3.23 gears in my 08’ single cab for some 3.73s or 4.10s and go from there! This will be my first build, everyone starts somewhere! This intake video just goes to show how well factory intakes can be especially the tbss! I believe the great equalizer boost could be in my future 👀
TBSS is good stuff
TBSS it is, Seems like the best bang for the buck
Hey Richard thanks for teaming up with kyle #goatropegarage. Your format and editing is just what we like. Some pics along with your words of wisdom is all we need.
Awesome thank you!
I'm watching this video while hugging my beloved FAST 102 intake hoping it makes it. :(
That is funny! I have the FAST 102 as well. Love it
You spent your money wisely. The FAST 102 is an excellent intake manifold.
1
Fast 102 is king n/a out performed every intake in the test only way I would run somthing different would be if i was gonna go boosted
Tberg725 what would you run boosted
so what I learned from this was... just run the stock truck manifold it comes with ( provided it fits under the hood) and spend your money on a terminator ECU. was seriously considering running a dual plane carb setup but in reality... I'd be spending more money to make less power. really wanted to see more out of the dual 4 setup but that was a huge let down. looks cool but thats about where the buck stops. thanks for doing these tests and sharing the info in such detail.
So how about keeping the stock truck intake and spend the money on porting it!?
Thank you Richard. You have broken down a lot of walls for me. 👍👌
Nice work man. Thanks for taking the time to help us spend our cash wisely.
Richard!! Where's the BMR Equalizer? I think it deserves a run too!
it wasn't out when this was run
Thanks Richard! this info is gold
Man, this video is absolutely amazing! Your channel is one of the best on UA-cam in my opinion. It would be THE best, if there would be more Mopar bb stuff ;)
Wow, thanks!
24:07 :P Man that BBK started whoopin some ass didn't it. James done snuck on here and opened a bottle in the dyno room. lol
Have you ever done a duration vs lift LS cam test? How much power does a "low lift" .560 (cheap stock replacement valespring type cam) 220-225ish duration cam make vs a .600 lift 220-25 duration. Possibly going to the extremes of 200-210ish duration 600 lift cam and a 230 ish duration "low lift" cam. Mainly interested since most stock LS heads dont flow anymore at .600 than they do at .550.
Wow great vid, I hope people appreciate all the work it takes to make this 👍👍
Id like to see this test on the coyote motor. I hear the late model truck intakes proves to be better than lets say the boss 302 intake etc. Solid LS video i enjoyed it.
Fords out too much to get any hp out of them. You know that already !
Looks like i picked best intake for torque TBSS FTW. Only bested by lsxr which is 9 times the cost.....
I was hoping to see the Dorman 3 piece truck intake tested...cool video...crazy how fast 5yrs fly's by since I 1st read this...still cool as hell..thanks!
I have tested Dorman
O.K. Richard, thanks again for working you ASS off to educate me !! Runner length is key to tuning this stuff, (you've been telling us that forever !) Here's a test I would like to see...I have the same dyno you have,and the ECM wideband stuff on my Super Flow Dyno, the question is ...WTF? Most of the stuff I do is carbureted(approx 75-80%) I noticed that my AFR readings are sometimes far apart from each other. The one side will be nice and sweet mid to high 12's on AFR, but the other side will be sometimes 10 or 11:1, It seems that the dual plane stuff is worse, but sometimes even the single plane stuff does it.I've swapped jet sizes side to side, I've swapped sensors,and even swapped sensor cables side to side,and the readings still stay the same.(It's not the Dyno, or ECM Wideband system.) I've tried cutting the center divider on the dual planes and/or running a open spacer under the carb. that usually helps, but no always. I've noticed that the dual plane intakes with the center divider that goes to the top, never runs smoothly after 5500 ish,as well as losing power.
thanks man , you're AWESOME !!!
If it is an LS-trying flipping the intake manifold 180 degrees-it fits both ways
@@richardholdener1727 .Thanks man! No I'm talking about most every engine I test, it seems as if the thing has a dual plane it's worse, but still dual planes are terrible !. I suspected the sensors/or sensor boxes,So I swapped sensor side to side, no change, then change sensor box side to side, still no help. Grrrr.. Thank you so much for all your hard work, I can't even imagine how much time you spend testing .
Do you think I would benefit much from going with a FAST LSXR intake over a ls6 intake with this setup?
5.7 LS1 (2000 Trans Am) with stock bottom end
• HEADS: Stock 243's decked 20 thousandths
• CAM: Comp cam 54-446-11 .595/.598 232/234 112LSA
• INTAKE: Ls6 intake
• INJECTORS: 60lb Deka
• HEADERS: 1 7/8" Long Tubes with true duels out the back
if the heads are not ported-then the fast might add 12-15 hp
I'd love to see water/meth port injection on a long-runner manifold. I'm guessing it'd need to be custom. The only bolt on I know of is Snow's port injection for the Holley Hi-Ram.
This channel is soo underrated 🤘💥
I love this video, because it told me everything I needed to know at the 2:20 mark. Looks like my old stock 5.3 is gonna keep the stock manifold until I muster up enough money to get some goodies internally. Haha thanks for the info guys!
