- DOES A HI RAM MAKE MORE LS POWER? DO CARBS MAKE MORE POWER THAN EFI? HOW WELL DO TUNNEL RAM INTAKES WORK? HOW MUCH POWER DOES THE STOCK LS3 INTAKE MAKE? IS THE LS3 FAST LSXR INTAKE GOOD? HOW WELL DOES THE MAST SINGLE PLANE INTAKE WORK? WHICH ONE MAKES MORE POWER? ALL THESE QUESTIONS AND MORE ARE ANSWERED IN THIS DYNO VIDEO ON AN ALL-ALUMINUM, HIGH-COMPRESSION, 468 LS3/7 STROKER. ALSO TESTED, CNC-PORTED LS7 HEADS! LOTS OF GOOD INFO IN THIS SHOUT OUT TO TUNNEL RAMS!
Blessed are thee with stroker cranks
Hi Richard, the only thing that would have been awesome is if aem, snow or one of the other water/methanol injection companies hooked you up with a 8 injector or throttle body plate injection system so you could show that those gains were primarily charge cooling on the injected application of the tunnel ram.
Wow, this series of tests really demonstrates the impact of charge cooling.
Love the videos Richard. Always watch at 1.5 speed and you're still listenable. Cram in so much info during a coffee break!!
Increased atomization with the carbs on high ram is a huge deal one of the reasons turbo charging works so well. Would be cool to see how hillborn injection stacks would of worked on that stroker.
Still get more with a big single 4bbl! Seen Nelson Racing Engines test the difference on a build they were doing. Also learned from them you gain like 100+ horsepower with long tube headers over zoomies! That was on a 2500hp motor, but still.
UTG did a video yesterday over the tunnel ram intake manifold
he's not a dyno guy
Been Very Happy with Bryce's work myself. He is doing my SB Mopar older EQ heads now.
I always appreciate your testing Richard! I clicked on this vid because i have been thinking about doing the high ram for my sons 351w in a ranger street/strip project. Thought it would look cool sticking out of the hood... We are only looking at 5-525 hp , but in 2400 lbs , should be fun little deal. Thanks for testing, helped me make a decision..
Go for it!
I was thinking about how old-school jet boats are trending again. How about a typical 500-650 hp BBC or small block and compare different brands of old and new tunnel rams and dual-plane intakes that are used on boats that typically spin between 3500-5500 rpm. If there's a low-end to mid-range rpm tunnel ram I'd like to see it.
Carb for the win on tunnel ram!!!
There's a reason this intake costs 900-1100 dollars now I see why! Great video 😁
This is definitely due to the higher flowing heads, particularly with the much larger LS7 intake valves and slightly increased lift.
I really enjoyed my LS7 headed LSX 427 ci you see in my profile pic. You could probably run a smaller cam without sacrificing much power.
what do the LS7 heads cost?
It all really depends on cost. Stock used with rockers probably $1,500.
I learned I want that stroker with the ls7 heads for my next build!
Richard mentioned his 495 build in the vid. I got to go back and read that article again. The LS platform is soooo cool
i had a tunnel ram on my 396 BBC and guys would say that doesnt make any power but i could feel the power gains
I believe there was some "give and take" with the LS7 parts. Upside: better flowing heads & more lift. Downside 1300cfm with the two 4150 carbs vs. the lower flow of the 4500...
first problem he is using a engine that likes boost not a tunnel ram u need high compression for a tunnel ram the higher the better i run 13.5 to 1 for my tunnel ram on a pro built engine i get over 1200 hp on pump gas on a 327 but it is really built and the carb test he had it over carb no balance with the fuel makes a big different i lost 400 hp just because i had it over carb running 2 650 had to drop to 485 carbs gained a lot first thing u need to blue print it then build it not just through parts on it very very bad test .
@@jeffrey4547 1200hp out of a NA 327ci with 13.5:1 on pump gas? 3.6hp per CI is amazing. I’d love to see a video of that thing running.
I dont care what anybody says, carbs rock and much simpler. Numbers dont lie
Carbs alot simpler and easier to dial in than efi...I agree carbs rock dude!!! ⁸
Not sure if you've done it. But, seeing the intake manifold temp. difference from efi to carb would be interesting.
Cooler and denser air/ fuel charge temp contributed to power gain with carbs over efi..
That setup is similar to my dream street strip big single turbo build with no budget. I picked up a 2008 3valve mustang which is something I would never do I've always liked how they look but they ain't very cheap and I don't know as much as I should about the platform I've had a turbo is sn95 and fix body but they where way more strip than street and I have a 2000 Z28 small tire stock suspension car grudge race track of street and I run some N\T stuff and no prep stuff on and off the past two years and it gets most of my money just to keep it ready to party but I have been wanting a quick reliable street car that's actually nice and comfortable for a while now. my pawpaws buddy bought the mustang new and besides a k&n filter it's bone stock and in amazing shape it still looks new inside and out and under the hood & every where else with 73 sumthin thousand miles sonic blue paint I got the deal of the century on it paid 4500 bucks for it! The little 4.6 surprised me even though it's a automatic trans so it got me wondering how fast I can go before kick in the rods out of it full weight like I would drive it on the street before I throw the nice little aluminum 5.3 with rods pistons and PRC cc'd 225's and forced inductions 85mm t6 1.32 exhaust housing and th400 with a holley terminator setup. Id like to see if the sbe 4.6 will go 6.50s in the eighth with the trans it has I'm not trying to buy a Ford pattern bellhousing for my th400 I'll never use again unless coyote stuff gets cheaper lol the car is getting several suspension parts from bmr and team z and some strange double adjustables they are my go to sbhock, I've picked up a on3 single kit for the car it's complete besides the turbo and waste gate I'm gonna have to have a t6 flange welded on and I'm going to run a 60mms gate I already have a billet wheel s475 with a 96mm turbine and 1.15 56 housing I'm gonna use I really want to do a CAME deal with some mild turbo grinds but I just can't justify spending almost $2000 for the cams and all the other parts I feel need to be upgraded valve train wise I will probably just put some Pac valve springs in it because I'm not gonna turn it more than 6500rpm if it will make around 520whp and stay together and get a good converter so I can build a few pounds of boost foot braking it and on e85 or e90 it should run down in the 6's and mph pretty good if the od style Ford trans a lot of guys run in fast street cars aint super expensive I will go that route I think they are called 4r70's I'm not a big Ford guy but I know you can get a manual valve body and trans brake for those and a lot more converter options which ever I end up with it will be a ptc Dusty Bradford. I've been wanting to try something different so I'm gonna give it a shot lol I just don't want to spend 6000 dollars on a hand grenade that can go any time I haven't seen any boosted stock 3v 4.6s make much over 500 and from what I've read they don't last but I've already got the turbo kit a jegs brand sheet metal intake (not installed yet) that is supposed to bolt right up and use all the factory stuff and I'm gonna use the Bosch 210s I already have that intake makes less power bellow 4000rpm and supposed to make 13 more hp above that and says it will make power up to 7000+rpm I'm gonna try and run it like sbe gen3 ls stuff and try to keep the tourqe down in the lower rpms idk I will find out what happens in the next month or two lol but there is still light at the end of the tunnel I have a aluminum 5.3 and turbo that will make 1100whp and a nice th400! I just know I'm fixing to have to open up my wallet! LoL
Tunnel Rams is where it's at!
Richard with baseball cap and no glasses is like Clark Kent effect. I thought he had a helper
As always.. awesome sauce! Thank you Bald Dyno Jesus! 😁
I think think the tunnel ram on the final engine, with bigger carbs would have made 770 easy. I think this is my new plan when my current setup expires. Excellent test.
50% increase over a stock LS3.
750bhp is a lot of forward motion but what would the price difference be compared to a stock LS3 with 7-8 lbs of boost? 👋
from what i've heard, which is all anecdotal. Stock LS cranks don't enjoy boost over a long period.

You see the power difference you get from just the charge cooling from the carburetor.
Please please please test cool can.
You can do with just regular ice water and you can do with dry ice and ethanol which will be extremely cold
Because of the vaporization of the carburetor, it will still have charge cooling on top of the extra coldness.
As it's always going to give off heat when it changes from a liquid to a gas no matter how cold that liquid is
Rich needs to figure out a way to run every power adder known to man in one engine build.
He might turn Westech into a smoking ruin.
Boost is boost, I'm wanting to see some more volatile fuels used , can't really call it the big bang without nitromethane.
please see the three videos where i ran turbo, twin screw, roots and centrifugal blower on the same motor
@@richardholdener1727 yeah, but did you spool the huge oversized turbo up with a small hit of N20? Hehehehe
Volvo XC90 t8.2018ish ... Is electric , turbo and supercharged. A Dream SUV of mine forsure.
Wish Holley would make an intercooled low ram intake manifold for us guys who want to keep everything under their factory hood.
Could you do a ported ls3 vs small bore ls7 head test sometime, with a meaty cam going 7500+, prefer toward 8000
Hay Richard I would love to see a big comparison based on a 351w but truck motor I run a early 90's f truck as my work truck I am a heavy diesel mechanic would love to see a build comparison looking at building a massive torque monster based off the 351w but making the most torque below 5k rpm
I RELY WANNA SEE How that mid plate intercooler effects the flow rate and HP on the Holly Hi ram VS a say water to air or a air to air.
You need to do the hemi version. Hi ram, victor 2 , 6.4 intake and 6.1.
I believe the LS 7 heads two piece manifold 1050 CFM carb is the best combination
Tunnel rams are sexy critters
Yet another great video
As an aside..... those must have been some short ass Rods in that 468 test mule considering the stroke and the lack of a tall deck mentioned.
I'm surprised more guys don't go for the longer strokes. Aftermarket blocks or sleeves aren't cheap. I guess that is the reason
Like Thumper I'd like to see Hilborn Stacks. But seeing you have a Tunnel Ram do they make a top for an Enderle Bird Catcher. Aim the nozzles up for charge cooling on Alcohol.
Hey Richard could you do some holley high ram upper plenum comparisons? I want to see if the front mount has any advantage over the side mount as well as see how they compare against the fabricated steel upper plenum.
the front mount flows and makes less than the dual quad top
@@richardholdener1727 Thanks for the info but I was more thinking about the comparison ls for a fuel injected engine. I’m buying one for my small block ford and will need a new hood to clear a front mount but the side mount fits fine. I was curious to see if the front mount flows any better to make it worth it.
Speaking of charge cooling.
Have you tried testing a carb against a holley stealth sniper system? Dyno the same engine back to back.
I'm curious if that would still create a charge cooling effect. Like a carb would.
I can't be the only person who'd be interested in those results.
would love to see a throttle body injection vs port injection vs carb on the same combo and intake
Carb and tbi will produce very similar results. Port efi power will be down slightly but drivability will improve.
@@177SCmaro probably, but its possible that the tbi makes the most power due to not having a restriction that a carburetor has to have to pull fuel but still has the air charge cooling effect. and because its fuel injection you get a more stable AF ratio so lower torque numbers should be better then the carb set up, but is it as good as the port injection? actually testing all 3 would show it so we dont have to speculate
@@DBLDREW
Port efi when you want more precision, carb or tbi when you want a little more power. Probably the best set up would involve port efi for start up, idle and cruising and then adding in injectors just downstream of the throttle body to cool the charge on manifold designed to be "wet" but this is a lot of added cost and complexity/tuning for a relatively small power gain (only about 20hp on a 700hp engine).
The restriction of the venturi on a correctly sized carb is negligible in most cases (especially dual carburetors), but still worth noting.
@@177SCmaro a 20hp gain is not a small amount. But only one way to find out what it really is.. this is where @Richard Holdener comes in.. why speculate when you can dyno it and know
@@DBLDREW
On a 700+hp engine 20 hp is relatively small, ~3%. Atmospheric conditions can make a bigger difference.
It's not really necessary to test. In this video they tested efi vs carburetors on the same intake. tbi is going to be very similar to a carb(s). Again, venturi on a properly sized carb cost negligible hp relative to efi. So long as carbs are "big enough" a comparable efi tb without venturi doesn't do much, if anything. In other words, if an engine at a particular power only needs, say, 800cfm then putting a 1500cfm tb on it isn't going to do much, if anything.
Another awesome video! I would love to see what you can do with a 90's lexus 1uz-fe motor! I have 4 of them and want some ideas for making power.
boost
@@richardholdener1727 hey, thanks for the reply! I am currently locked down in p.e.i Canada, not one single dyno on this island so I would need to be able to street tune it myself. I wouldn't mind trying it but the base tune would be the hardest part I think. The factory ecu in these cars are trash so I'd have to start from scratch I think.
Pretty cool info! Seemed like the torque curve might be a bit flat, only 1.35 lb-ft/cu in. Not sure why it isn’t 1.4 or better, but as you said it’d be wicked in a fox body street mauler.

Very surprised to see that the EFI hi ram didn't outperform the carbs. Was the fuel mixture the same with both induction systems? ITBs with a staged injection system and one set of injectors above the velocity stacks would be cool to see put up against the carbs.
Carbs by virtue of where the fuel is sprayed often add a cooling element to combustion. Efi fuel is often hotter
I've always been curious about twin turbo on a carb tunnel ram? Can u put one turbo on each carb? Is it possible at all?... I'm a nos guy myself, but always wanted to know the answer.
YES
All major engine builders all agree carburetion makes more horsepower than fuel injection, it has always been the case even with advancements in fuel injection technology. Die hard fuel injection guys always down talk carburetors, mainly because they have no clue on how to tune them. Fuel injection gives better drive ability, and increased tuning options for all RPM ranges, easier to fine tune specific areas. Head flow is most likely the increase in power with the ls7 heads, as they are the most critical in making power as for top end parts go. It’s always the combination of parts, and when matched correctly throughout for a total package is the key. Good video.
It's not so much efi is arguing "it's better" it's more "we like the list of trade-offs efi gives us". If the budget is avalable I will usually trade a little power for absolute, rapid, automatic control over fuel and timing at every rpm and load. And I say this as a guy who's got both carbed and efi cars.
That said, efi can make you lazy since, once you get it set up and figured out it's so easy. I just grab a laptop for my efi car. I need half a toolbox full of carb parts to really dial in carbs to a knife edge and still they're usually compromised in one area at the benefit of another.
"carburetion makes more horsepower than fuel injection"
Nah, you can get the same charge cooling effect with ITBs and injectors placed above the velocity stack, that's why you'll see staged injection systems on some really high-end performance engines (Kawasaki H2, for example). F1 engines and Top Fuel engines also inject their fuel high in the intake stream in order to achieve this effect.
Ls7 has: a Higher Rocker ratio with a Better line of sight to the back of the valves in being a Raised runner..Also a smaller port in CSA and MCSA. Bigger valve, better valve angle at 12 degrees vs 15 degrees with the Ls3.
Owner of Both heads for a lq4 stroker 408..🤫 Shrink the exhaust valves and seats for any bore under .060 Darin Morgan shrunk my Speed pro Ls7 heads exhaust valve to 1.55 for a 4.030 bore.
Friend used a 4.065 bore and a Ls7 head
I learned those intakes aren't worth running unless you are reving past 7000rpm.
I love the edited "engine noise" LOL
One would think a multi port injection would make more power then a throttle body injection since you can get even fuel to each cylinder. What if you put a fuel cooler on the lines would that make a difference

Love your videos and data, been following for a long time and helped a ton. Better than backyard or Monday morning mechanics around here locally. Recently read articles again talking about carbs and getting the right size the first time. But, what formula do you use for a tunnel ram? I know that 2 450 Holley's aren't giving me 900 CFM.

if it has good heads to match-then twin 750s (with a high stall) or 650s

Why is nobody giving Nissan the love they deserve? The 5.6L twin overhead cam V8 they have has more potential than a 5.7L hemi.

@@richardholdener1727 my point exactly! The LS is getting all the attention and aftermarket support right now, but it's still limited by it's pushrods. The VE56 has more "junkyard turbo" potential than a 5.3L LS in my eyes, as long as the bottom e d holds together.
If the VE56 got the same attention as the LS then the Nissan 5.6 "should" outperform even a 6L LS. It's also in a WIDE variety of their service and consumer vehicles....... Richard.... Please turbo a junkyard Nissan 5.6.
I really want to see someone build a big power, big cube, TALL deck, LS7 head carbureted Nitrous Race Motor.
I wonder if, at that point, the cost might come too close to BBC territory, so people just end up going BBC in the end as it's a known entity.
Tunnel rams are cool. That much is certain...but long runners have their charm too.
Funny that on a 1969 440 a tunnel ram is long runner but on an LS3 it's short runners!!! I was expecting increases in low end power on this test when he switched to the tunnel ram but it lost low end. Then I realized the LS3 intake has longer runners than the tunnel ram. Cool test for sure!
I think the heads and rocker arms made the difference. I think the intake was a wash.

Ls7 heads over the ls3 heads on the same bore will make 30-40 more hp. It's definitely the ls7 heads. I've seen C6 z06 guys afraid of dropping a valve again will go down from their 600 rwhp hci ls7 to ls3 heads and make 550-560 rwhp. The ls7 heads really do make that much more power than an ls3 head.

The single carb just needs twin turbo!!!
Did you flow both of the cnc ported heads? I have zero information on the base difference between LS3 vs LS7 heads
I think the answer to your questions is. yes.
In all seriousness though, I am not so sure it was the charge cooling that netted you more HO on the top change. I think it was more the fact the air is not changing direction as it enters the runners from the plenum. Maybe even better distribution to the cylinders also. I cannot believe the airflow is not as prevalent at the rear cylinders vs. the front cylinders. Uneven power will effect the efficiency in a negative fashion. Would love to know if that theory holds any water. Fun stuff, Richard. Thanks

Lots of power, but just how streetable is this engine ? The little 5.2 Coyote can make as much power with a lot better fuel consumption
no
Not going to doubt you with less money and headaches to a naturally aspirated coyote 5.2 will need to turn 9200rpm to do so so I'm thinking it better be put together right using the most expensive highest quality parts available to do so and even then it will not touch these torque numbers these engines are making better off with the Ford new gas 7.3 truck motor it will be much more simple more cost effective and make way more torque than a 5.2 coyote but your entitled to your opinion and it will be more reliable and last longer than these engines the 5.2 coyote will be turning 9200rpm and the engines in the video turn 7200rpm think about it logically even if you made this kind of power with a 5.2 coyote engine it would be a edgy engine and wouldn't last very long and would wear out quickly turning this kind of rpm
I think the the high ram LS7 intake would of made 800 hp!.....well maybe 776 hp but rounded to nearest 50 hp
