3:42 That's a pretty good looking power curve already. I like the way power is close to 550 HP starting at 6200, and just hangs there. But I'm wondering something. If you would put strong enough valve springs in it, how much farther could you rev the engine until the power drops off to 500 HP? Saying you could get to 7500 rpm, you would have an engine that makes over 500 HP from 5500 to 7500 rpm. That way, when you shift to the next higher gear, you would already have 500 HP available. 7:30 Hey, look! The TBSS manifold adds power everywhere. Holdener Effect kicks in, making manifold more expensive everywhere.
I’m hearing this as...truck manifold flows up to 550 NA hp at 7k rpm, Tbss buys you 15 more hp, and then it’s $1k to get a manifold that makes as much as a 50 shot of nitrous or 2 psi of boost. Think I’m keeping the truck manifold.
Love my Mamo ported fast 102 worked well on my sbe ls6 and now works even better on my 427 ls3. Was planning on trying to find a trailblazer intake for old ls6 longblock now
Depends on your application but the Dorman or trail blazer SS per dollar spent seem to work well without a lot spent and would work well for street driving with a wider torque curve throughout most of the rpm range while being very respectable in the upper rpm range
Sbe turbo don't mind the torque loss down low because they cut timing at peak torque to try to make the engines live. That's one good thing about the high ram.
Torque is always important to me, the more I can get down low and mid the better.my SRT 10 boosted was a beast with stock exhaust manifolds, headers killed the power down low, up top great, but not worth the loss, intakes do the same thing..
Also need to keep in mind of the extra cost in fuel rails, bigger tb, possible bigger injectors, and the steam vent has to be modified for the lsxrt intake to fit. The tbss intake and 90mm tb is the most cost effective route to go in my opinion.
TBSS intake = DIY work, such as sealing the holes on the top and tapping your own MAP sensor fitting in the rear and hood clearance issues and possible firewall clearance issues, pending application, which can be solved with an angle grinder.

Richard if you pick any torque curve, any one and move it to the right to a higher rpm, it now makes more horsepower. If you gear both optimal. Will the higher hp curve outrun the lower hp curve. Anyone.???
Hi Richard, great video! Question: Im sure a lot of guys swap an LS into a muscle car and just use a stock cable 78 mm throttle body from an older truck intake that is easy to hook to gas pedal like I did with an adapting throttle cable. And as sloppy Matt Happel said in a video on MAC valve controlling table in terminator, a lot of guys first get turbo cars and crash because they go to lift the throttle and if over 50% throttle, many boosted turbo cars still have massive power when lifting and just keep going. Unlike a n/a that slows right away when you lift. Regarding above comment, Im thinking there is very little power difference to be gained by going to a larger throttle body on a TBSS intake. My combo now is TBSS intake, 799 heads, older sloppy stage II cam, 6.0 and twin S366 turbos with my older stock truck intake cable driven 78 mm throttle body! My buddy thinks I will gain big power by going to an aftermarket larger cable driven throttle body. Im thinking very little or no power gain and not worth the at least 100 dollar cost! Thoughts here? I cant find a video addressing this. Thanks for any input Richard! We greatly appreciate all your testing and experienced advice!!!
Richard , I have an early Lq4 dbw, is there a benefit to swap to the l33 truck manifold which is I guess the dorman, type fast? I can’t fit the tbss due to my heater hoses …and hate the ugly Lq4 , the l33 looks better
Richard, Thank you for all the knowledge and insights you've shared with the LS community. I have an idea for another intake video. Can you do a four-way comparison on a gmt800 5.3L: 1) stock truck intake and 78mm TB 2) TBSS intake, with the a 4-bolt to 3-bolt adaptor, and the gmt800 78mm throttle body. 3) TBSS intake with the gmt900 87mm throttle body 4) TBSS intake with an LS2 or equivalent 90mm throttle body The main point of the exercise being to bring to light how much power is to be gained or left on the table by the three TB options. If the 78mm & TBSS upgrade produces decent results, then the average NBS enthusiast doing the swap could potentially avoid shelling out $250-300 for the X-Link 8-pin to 6-pin adaptor. Clearly the 78mm TB becomes the bottleneck in that system. The 90mm is the most potent TB for the high end of the RPM band. What about real world conditions under 5500rpms? I believe this analysis would shed some light on the cost/benefit ratio for the swap. If someone could get say 75% of the performance gains, with half the investment, they may conclude that the swap is more palatable. On paper the 90mm vs the 87mm will produce marginally different results. How much is to be had with those extra 3mm, and is it worth the investment?
@@richardholdener1727 That makes sense. Thank you for for the timely reply. Could you possibly run a cable operated 78mm TB off a 99-02 truck instead? That result could be compared to a cable operated 90mm TB on the same engine/intake combination. The 87mm comparison would have exit the analysis, but those results should be very close to the 90mm unit. The question becomes how much increase is actually observed for the extra 12mm (78 vs 90) of throttle body opening. Thank you again for all the knowledge you've shared with us over the years.

It's the same as the fitech, Holley Sniper, ebay cheap brands.. He's tested it, it makes good power but it's even further in the rpm range then the hi ram. It's a good one to get if you are turning 8k and don't care about bottom end.
The dyno sheet you are claiming to compare a factory truck to holley at 8:35 is the "holley Dual Quad manifold" (a high ram dual 4 barrel TB / dual carb manifold)... as the dyno chart reads ( not the single inlet TB high ram pictured) ..which is hardly similar to a stock manifold or normal street application.
@@redlinepullers3277 it's going to be a L83 engine. They are a nice unit. All aluminum, 11.0 to 1 squeeze. Jeremy at FasterProms has done some work with them. Stock they are 355hp. All the same things that work on ls engines work here too. I think they have a more mild camshaft than the Lt1, l86, L8t bigger engines and a take out camshaft might be a cheap upgrade. the 6.2/6.6L camshaft has 7° more duration at 0.050 and 0.051 more lift on the intake. I know it's not much but you might be able to get one for almost free. The Lt2 intake from the corvette c8 needs a little work to fit but it is the best factory intake for those engines and clears the hood. The L83 intake is a weak spot even on a stock truck and the L86 6.2l truck intake is an improvement. There is very little cost difference between the L86 intake and the Lt2 intake. The factory truck exhaust manifolds are pretty good but headers are better depending if they're legal for you. The trucks have a really restricted air intake system and exhaust. A good cold air snorkel and higher flow mufflers is an idea. The 6.2l trucks have 40 less horsepower than the corvette with the same heads, camshaft and compression. The only difference is the intake manifold, exhaust manifolds, and intake and exhaust ducting. The air intake system on the trucks really keeps the drive by noise low, but the horse power low too. Good luck with your truck
Hey there. I have a question. You've always answered in here to my surprise this is little long please bare with me. So I have a 6.0 ls big turbo car I used a btr stage 4 turbo cam. Engine is out due to broken piston. Going forged. While it's out I'm considering installing a btr stage 4 truck cam. Based only off how good they sound at idle. But keeping everything else the same (still 76mm turbo) what in your opinion I'm I going to loose by switching to the truck cam over the turbo cam. Thanks in advance
Ls6 with btr cam kit long tube headers 90mm throttle body hitting the rollers in 2 weeks was gonna be hitting it with 150 shot would a manifold be worth grabbing b4 the tine that’s my question?

Now what were the throttle bodys used on these manifolds? Factory ones are 77mm and im looking to get closer to 100mm. Can't find a 3 bolt 8 pin close to that even after being told there is a 92 or 95mm that is 3 bold 8 pin. If you know one PLEASE put the part number on here for me. Thanks.
I don't know what application you have, but bolting a bigger tb on a smaller 3 bolt manifold is a waste of time. But to answer your question, you need a ls3 90mm tb and the x-link to adapt the pins.
@@richardholdener1727 I’ve been trying to find a better intake manifold for my L9H 6.2L to go with my BTR stage 4 truck cam Been searching threw all your videos trying to find something related to the set up I have Thanks for your time Richard
It totally depends on what you want your engine to do. There's no inherent "best cam" ... there is a point where a cam can be too large or too small for an application, but there's some room to play. That "room" is where you can determine your driveability, rpm range, type of torque production, etc.. Another question that could be asked: what do you plan to do to the car in the future? Will you stop at just the cam? Or will you add heads? If you want something with good manners but an aggressive idle, 230-235 duration on the intake side would be good. 227-230 if you want something fairly mild, but will still give you a good power bump. The LSA will have an effect on idle quality and torque production as well.

already tested-that vid is up
Richard if you pick any torque curve, any one and move it to the right to a higher rpm, it now makes more horsepower. If you gear both optimal. Will the higher hp curve outrun the lower hp curve. Anyone.???
more hp will win
Hi Richard, great video! Question: Im sure a lot of guys swap an LS into a muscle car and just use a stock cable 78 mm throttle body from an older truck intake that is easy to hook to gas pedal like I did with an adapting throttle cable.
And as sloppy Matt Happel said in a video on MAC valve controlling table in terminator, a lot of guys first get turbo cars and crash because they go to lift the throttle and if over 50% throttle, many boosted turbo cars still have massive power when lifting and just keep going. Unlike a n/a that slows right away when you lift.
Regarding above comment, Im thinking there is very little power difference to be gained by going to a larger throttle body on a TBSS intake. My combo now is TBSS intake, 799 heads, older sloppy stage II cam, 6.0 and twin S366 turbos with my older stock truck intake cable driven 78 mm throttle body! My buddy thinks I will gain big power by going to an aftermarket larger cable driven throttle body. Im thinking very little or no power gain and not worth the at least 100 dollar cost! Thoughts here? I cant find a video addressing this. Thanks for any input Richard! We greatly appreciate all your testing and experienced advice!!!
MORE POWER TO BE GAINED ON A MODIFIED NA COMBO GOING FROM 78-92 MM THROTTLE BODY ON A TBSS INTAKE. NONE TO BE GAINED ON A TURBO MOTOR
@@richardholdener1727sup brother just wondering if my ls2 manifold would fit on my lq4
Richard , I have an early Lq4 dbw, is there a benefit to swap to the l33 truck manifold which is I guess the dorman, type fast? I can’t fit the tbss due to my heater hoses …and hate the ugly Lq4 , the l33 looks better
the L33 is the same as the early ruck
@@richardholdener1727 why does Dorman cost $600 when you can be the early truck for like $30? Looks?
Richard,
Thank you for all the knowledge and insights you've shared with the LS community. I have an idea for another intake video. Can you do a four-way comparison on a gmt800 5.3L:
1) stock truck intake and 78mm TB
2) TBSS intake, with the a 4-bolt to 3-bolt adaptor, and the gmt800 78mm throttle body.
3) TBSS intake with the gmt900 87mm throttle body
4) TBSS intake with an LS2 or equivalent 90mm throttle body
The main point of the exercise being to bring to light how much power is to be gained or left on the table by the three TB options. If the 78mm & TBSS upgrade produces decent results, then the average NBS enthusiast doing the swap could potentially avoid shelling out $250-300 for the X-Link 8-pin to 6-pin adaptor. Clearly the 78mm TB becomes the bottleneck in that system. The 90mm is the most potent TB for the high end of the RPM band. What about real world conditions under 5500rpms? I believe this analysis would shed some light on the cost/benefit ratio for the swap. If someone could get say 75% of the performance gains, with half the investment, they may conclude that the swap is more palatable.
On paper the 90mm vs the 87mm will produce marginally different results. How much is to be had with those extra 3mm, and is it worth the investment?
I can't run dbw throttle bodies
@@richardholdener1727
That makes sense. Thank you for for the timely reply. Could you possibly run a cable operated 78mm TB off a 99-02 truck instead? That result could be compared to a cable operated 90mm TB on the same engine/intake combination. The 87mm comparison would have exit the analysis, but those results should be very close to the 90mm unit. The question becomes how much increase is actually observed for the extra 12mm (78 vs 90) of throttle body opening.
Thank you again for all the knowledge you've shared with us over the years.
@@richardholdener1727I have a 5.3ls btr truck Norris cam headers long tubes 4.10 gears 3200 stall cold air filter what's the best intake and tb setup for a gen1 5.3
I watching these videos and I see thr fast talked about so much. Yes it produces more power but the cost! I like to see more tests on low profile intake. I have a LS2 I want to boost and can't fine much info on. Other then early NA applications. It is what I have. I need hood clearance and on a budget and this is the intake I am running. Have you ever tested a stock LS2 with boost?
the ls2 works fine under boost
What do you think would be better the tbss intake it the fitech Composite intake
I’m going to run the FAST LSXHR. I found very little testing of it out there.
I can only assume it’ll act pretty similar to the Holley hi-ram
I tested the fancy Carbon TR version
@@richardholdener1727 yea I’d like to see a test with the different size runners on it. I’m hoping it reacts like the lsxr. Im pairing it with the longest runners on a 428” ls3 with big ported heads and a pretty healthy cam for a auto cross/road race/ street truck build.
@@TheDakotaThurmond similar yes but the LSXHR has 6.5, 8 and 9” runners. The Holley high ram has 6.5” runners. The only test I d seen of the fAST used the short runners.
@@brandonloll4262 I did some more research after my comment and noticed where it said they had variable runner lengths, forgive me
I'm interested in what I can do to a bone stock LM7 5.3L engine to improve the performance without a cam swap or removing the heads, and also without putting a turbo on it? Do you have a video outlining that?
headers, tune
@@richardholdener1727 that's it? No bolt on items I can put on it to get more hp? Intake, 92mm throttle body, better injectors? None of them will help?
How about BTR Equalizer intake
very high rpm
@@richardholdener1727 can you do that test
Love it bro
Richard did you find out what happened to the Northstar supercharger on the 6.0 ls
not yet
Definitely ready to see what that outcome is, been wondering for awhile
Steadily acquiring the parts to put my Northstar supercharger that I just bought on my new 6 l with the custom Brian tooley cam so I'm chomping at the bit waiting to see!
O and Thank you Richard for your time doing this. And nice snakes 😜
Im going for a roll racing truck, already have a high revving cam and want to see what intake makes the most power uptop? (Hand porting heads soon)
see the ls intake video-tested all of them
Is it best to utilize the tbss throttle body or is an adapter to install a 92mm? 6.0, SS2, may add a 100-150 shot.
match the tb to the intake opening
I'm solid with a 6.0 under an ls3 top end. Need more? Port the ls3 intake and the add nitrous
How much do you think it would cost to do that compared to buying a fast intake
@@b.valdez2426more but the flow number of the heads can't be matched with cathedral port. So to me it's cheaper to do oem take offs and swap it on vs ported cathedrals and then get a fast intake
Could you test that Speedmaster fabricated intake that is like $325?
It's the same as the fitech, Holley Sniper, ebay cheap brands..
He's tested it, it makes good power but it's even further in the rpm range then the hi ram. It's a good one to get if you are turning 8k and don't care about bottom end.
Long runners rule!
What about the victor jr with an elbow and what about those cheap aluminum intakes????
The dyno sheet you are claiming to compare a factory truck to holley at 8:35 is the "holley Dual Quad manifold" (a high ram dual 4 barrel TB / dual carb manifold)... as the dyno chart reads ( not the single inlet TB high ram pictured) ..which is hardly similar to a stock manifold or normal street application.
I'll check-I test so many
I just bought a used 2017 chevy silveradoZ71 with a 5.3L could u tell me what gen and model it is and what r some good mods r for it
that is an LT-based motor-an l83 most likely
@@richardholdener1727 ok thanks any good bolt on mods
@@redlinepullers3277 it's going to be a L83 engine. They are a nice unit. All aluminum, 11.0 to 1 squeeze. Jeremy at FasterProms has done some work with them. Stock they are 355hp. All the same things that work on ls engines work here too. I think they have a more mild camshaft than the Lt1, l86, L8t bigger engines and a take out camshaft might be a cheap upgrade. the 6.2/6.6L camshaft has 7° more duration at 0.050 and 0.051 more lift on the intake. I know it's not much but you might be able to get one for almost free. The Lt2 intake from the corvette c8 needs a little work to fit but it is the best factory intake for those engines and clears the hood. The L83 intake is a weak spot even on a stock truck and the L86 6.2l truck intake is an improvement. There is very little cost difference between the L86 intake and the Lt2 intake. The factory truck exhaust manifolds are pretty good but headers are better depending if they're legal for you. The trucks have a really restricted air intake system and exhaust. A good cold air snorkel and higher flow mufflers is an idea. The 6.2l trucks have 40 less horsepower than the corvette with the same heads, camshaft and compression. The only difference is the intake manifold, exhaust manifolds, and intake and exhaust ducting. The air intake system on the trucks really keeps the drive by noise low, but the horse power low too.
Good luck with your truck
Look in your glove box. There should be a sticker with a list of alphabetized codes. That’s all the options in your vehicle including engine type.
It is a LT-1 engine, not LS
Hey there. I have a question. You've always answered in here to my surprise this is little long please bare with me. So I have a 6.0 ls big turbo car I used a btr stage 4 turbo cam. Engine is out due to broken piston. Going forged. While it's out I'm considering installing a btr stage 4 truck cam. Based only off how good they sound at idle. But keeping everything else the same (still 76mm turbo) what in your opinion I'm I going to loose by switching to the truck cam over the turbo cam. Thanks in advance
are you maxing out the turbo?
@@richardholdener1727 no. I still had plenty of turbo and injector. I was happy with the power b4 I lost a ringland
Ls6 with btr cam kit long tube headers 90mm throttle body hitting the rollers in 2 weeks was gonna be hitting it with 150 shot would a manifold be worth grabbing b4 the tine that’s my question?
you have an LS6 intake with a 90-mm tb?
@@richardholdener1727 apparently it’s a ported ls2 throttle body was on car when I bought it I threw a btr cam kit on her and long tubes i just don’t no if I should throw a manifold on her it’s gonna be my street car my no prep car is completely built 5.3 from oil pan up and power glide I just don’t no for a fun street car if it would be worth getting intake manifold lol
Have you ever run a junkyard 8.1 intake manifold? I'm putting together a 496 and have been thinking about going EFI.
no sir
@@richardholdener1727 ever thought about it? Hook a factory intake up to a Holley then compare it to the two styles of Holley EFI manifold.
8.1 has completely different intake port pattern than a traditional big block chevy.
Richard, do you feel that if the LSXRT was ran with a 92mm throttle body it would make more torque on the 6.0 or a cathedral headed 6.2??
throttle body size will only change top end power-not torque production
On the tbss intake test, was that with a 3 bolt throttle body with the 4 bolt throttle body adapter or with the 4 bolt stock DBW throttle body?
THE TBSS HAS A 4-BOLT 90MM TB
Now what were the throttle bodys used on these manifolds? Factory ones are 77mm and im looking to get closer to 100mm. Can't find a 3 bolt 8 pin close to that even after being told there is a 92 or 95mm that is 3 bold 8 pin. If you know one PLEASE put the part number on here for me. Thanks.
I don't know what application you have, but bolting a bigger tb on a smaller 3 bolt manifold is a waste of time. But to answer your question, you need a ls3 90mm tb and the x-link to adapt the pins.
what intake are you running a 3-bolt 100mm throttle body on?
Have stock manifold for now. Was asking about 92-95mm. Engine build is costing more than I wanted. Trying to cut cost on top end for now.
Why are the lsx 454 and 454r oem cams so expensive compared to aftermarket
Paying for the name and bragging rights

Would the LSXRT intake for rectangular port heads like L9H or L92 6.2L be the best ?
Next video maybe?!.
I spoke about that-the stock LS3 intake works just as well. The cath port Fast is a big gain, the rec port fast is not.

Thanks for your time Richard
@@richardholdener1727 what do you think about ported truck L92 or TBSS INTAKE ? Better gains on the low end ??
Richard what is the normal oil pressure on the ls engines I’m putting in a new oil pump and need to know before I put in the wrong pressure spring
oil pressure increases with rpm on an ls-especially with factory bearing clearances
Stock should be 35-40, over 5500 rpm you shoulf have HP, bear in mind a HV pump does wonders for a older engine
Whats the best cam for full bolt on ls7 z06? Have you done a comparison?
It totally depends on what you want your engine to do. There's no inherent "best cam" ... there is a point where a cam can be too large or too small for an application, but there's some room to play. That "room" is where you can determine your driveability, rpm range, type of torque production, etc.. Another question that could be asked: what do you plan to do to the car in the future? Will you stop at just the cam? Or will you add heads? If you want something with good manners but an aggressive idle, 230-235 duration on the intake side would be good. 227-230 if you want something fairly mild, but will still give you a good power bump. The LSA will have an effect on idle quality and torque production as well.
how much power do you want to make?
@@richardholdener1727 around 600 wheel. But have some drivabilty, not looking for it to drive like stock but he able to drive it on the street. The car has PRC heads, fast 102 Nw 102 Tb, headers
