- GT-40 vs THE WORLD! WHICH FACTORY GT-40 INTAKE MAKES THE MOST POWER? WHICH INTAKE SHOULD I RUN? HOW WELL DOES THE JUNKYARD EXPLORER INTAKE WORK? IS THE 90-DEGREE, 5.0L EXPLORER ELBOW RESTRICTIVE? WHICH ALUMINUM FORD COBRA INTAKE MAKES MORE POWER, THE 93 COBRA/COBRA R OR 94-95 SN95 COBRA? HOW MUCH POWER IS A FORD 5.0L INTAKE UPGRADE WORTH? CHECK OUT THIS VIDEO WHERE I COMPARED THE TUBULAR GT-40, 93 COBRA, SN95 COBRA AND 5.0L EXPLORER INTAKES ON THE SAME MODIFIED 5.0L EFI MOTOR. I EVEN COMPARED THE EXPLORER WITH AND WITHOUT THE 90-DEGREE ELBOW.

The tubular gt-40 is the coolest looking intake manifold ford ever made imo
Agreed,.... but it's 10x the price for 10+ HP beyond 5400 rpm.
I paid $143 total for my non-EGR and throttle body.
SHO Taurus gets my vote.
@@mattfarahsmillionmilelexus Yamaha designed that intake and manufactured it in Japan. The SHO were assembled here, after receiving the completed engine assemblies from Yamaha in Japan.
1994 SN Cobra had stock 60(!) mm tb with a 70(!) maf. It had larger inj 24lb vs 19lb for GT. Also larger fuel pump and a special “cobra” ecu program (more timing, etc). Upgrading to a 65 or 70mm tb was the first upgrade along with more timing. I bought it new in 94…miss her😢. Peace
I love my fabricated GT-40 intake. It's definitely the best looking Windsor intake, Back in the day people new in stock form the GT-40 performed a tad better, but the cast Cobra intake allowed for porting or extrude honing.
The ford explorer Is my favorite for the bang for the buck and I have had excellent results ! I put explorer cam in a non ho once and it roared pretty good with the explorer intake ! Also I built a explorer gt40 e 303 in a 90 thunderbird that was excellent!!
Still love my GT40 tubular intake. It is a great street intake. I know there is better flowing intakes but I like the looks of it. Actually when I got this intake 20+ years ago, there was not many aftermarket intake available. Great video. I wish you put a chart up so we could see all the differences at once.
ALL OF THEM ON 1 GRAPH WOULD BE TOO CONFUSING
@@richardholdener1727 Chart, not a graph like I said above. Not being rude.
The best gt 40 intakes tests if seen on you tube! Thank you Richard!
In Australia we had very few cars with the GT40 tubular intake, but 1998-2002 our 5 litres all had the Explorer manifold - but with a straight blanked EGR block (with no EGR). As well as looking neat I think it improved torque a little much like your Kenne Bell elbow.
That's a rare Explorer intake without the cast in tab for the cable stay. I've only seen two in the boneyards.
Thank you Richard, another great video. I'm learning a lot.
Be blessed brother
The gt40 was always my favorite among the factory intake manifolds.
Love Your drive / effort on making great content !! Thank you!
Thanks for this video! I have an Explorer GT40 with a KB style elbow adapter on my SN95. I am a budget builder so it is nice to know that I am not losing that power in comparison to the other rarer and more expensive intakes. We may not be too far away from being able to 3D print some new upper intakes. I am looking forward to that 😀
Man I keep getting surprised by your backlog of excellent sbf demonstrations. You are the man... I'm gona go buy a gt40 upper
Good confirmation that my choice of tubular on my car is the way to go. Good content!
Great video. I have a 93 cobra upper with a explorer lower ported by tmoss. I would love to have the tubular gt40 but they are going for crazy money. I have always loved the look of that intake.
Love it! Taking back 20 years !
Good video sir. I’m running tubular GT 40 w/V1 s trim. I know there is better out there but it looks cool as hell.
Love your work Richard.
Awesome. This guy is working on the two motors I'm building 302sbf and the 3800. 93 Mustang LX and 99&01 GTP. This is a great sign lol
Wow I like the nice elective surgery infomercial music during the engine introduction
Love this video!
For the money.. port a stock explorer intake ( upper and lower) and you'll be way ahead price wise than any of the intakes tested.
Yeah but you can also port all the other intakes and then it would out power the ported Explorer intake.
@@matthewvarnam4302 That is true, HOWEVER not by much and definitely for twice/three times the money!
Maybe if you have the ability to do it urself! I you gotta pay a professional you won't! I watch Richard's vedios every day. But, I started of with 5 liters. Once we put the first cheap cast flattop 351w in I never looked back! Made at 6000rpm what a 306 made at 7000! And shot 150 on it 4 -5 times a night 3-4 times a week! On pump gas!! Sold it to move up to a high dollar solid roller motor. Worse decision ever, it was fast! But race gas and maintenance is a bitch!
There's only so much port work you can do to the tubular upper. The explorer and cobra can be cut open, ported and welded back up. You also have the kink near the throttle body on the tubular. A ported GT40 styles intake shootout would be interesting
@@adamrushka8096 I'm not talking about the tubular one.. but you're right
I sure wish you got more views for all the work you do for us!
I like the 93 Cobra .. the original ran neck n neck w the tubular GT40. Did it right.. right out of the gate. Enjoyed the comparison.. good job.
Great tech! Thanks for all of your SBF content. I wish we could get you to test the porting work of the two “internet famous” guys. We’d see who’s really on point with their ported EFI GT40 lowers! (Edit for a typo)
I love the comparison videos and my favorite is the GT-40 but I like the cobra intake when it’s extrude honed!!!!
Very interesting video, I didn't think there was going to be that much difference between the Explorer intake vs the Cobra intake. I would like to know if both cobra throttle bodies were the same size or not.
I want to say think you for all these Videos you do. I show all my customers your videos. Keep up the Awesome work.
I’ve always wanted a tubular GT40 intake, they look pretty cool!
Thank you for the 5.0L tech!
Great video, wished you could have included the regular 5.0 intake.
Great work!
I love these types of videos, as the owner of an 85 GT though I’d really like to see an old carb intake shootout on these engines, like the stock one, the “performer”, performer rpm, air gap, victor jr ect, and stock vs aftermarket heads with the intakes?
I tested the Performer, the RPM, the Torker and Vic Jr. way back
You are living the dream my man!
Picking up a 302 with a .520 lift cam (unknown brand), 93 Cobra intake, 65mm throttle body, and a 70mm mass air for $800. I think it's a pretty fair deal. Can't wait to get my fox moving again.
Sounds awesome throw some gt40 or P heads on that and it'll be a ripper !
@@foxbodysandfreedom8595 it just has some ported and polished E7s on it. I plan to get a decent set of heads in the springs, hopefully she'll be finished here in a couple weeks!
I'd be very interested in seeing an intake shootout of early SBF intakes: OEM Cast iron 4bbl, Shelby high rise 4bbl, Edelbrock F4B, performer, performer airgap. It would be great to see how far intake design has progressed.
I enjoy all of these tests. Just FYI the lightning GT40 upper is slightly different than the Ford racing GT40 upper. I have a Ford racing GT40 upper and the lightning top cap will not fit on it it is slightly shorter in the cap that came on it.
Interesting, as yet again my factory Aussie XR8 220kw (295hp), combo has what looks like a stock Explorer manifold, BUT it also has a bigger Tickford Straight-on 70mm throttle body !!
Great info. You can buy a whole explorer for the price of the tubular GT40 intake.
Thanks for doing this video , its good stuff ! I did a topend kit on my 94 cobra trickflow 170 fast as cast, 75mm throttle body and port matched for larger opening , 4.0" power pipe cold air , pro-m 80mm maf , 1" phenolic spacer between upper and lower ,custom anderson ford motor sports B-31 Cam 270/280 , 218/228 , .544", full exhaust syst. Had lower intake ported , stock it flows 205-210cfm ,ported flows 250cfm. Was done by TMOSS PORTING , car has excellant throttle response with 3.73 gear ! would like to see the results for the ported lower intake , larger throttle body and port match the upper intake at throttle opening. Thanks for all you do for us motor heads we love it , it saves use a lot of money and time , keep up the good work !!!
I heard TMoss porting charges ALOT, and only ports the less restrictive lowers? How much did he charge, and in what year did you have your lower ported by TMoss?
Tried n true tubular GT40 is still sexist and most powerful!! I miss mine!! The optional cover with the horse was a sweet touch!!
Love to see 351 truck intake vs carb vs any other intake manifold.
Impressive how well the Exploder manifold performed
I don’t know why anyone is surprised they all perform the same basically. They’re all essentially the same upper intake manifold just in different looking packages. Very slight differences between them due to the vehicles they were required to fit into, but they’re all designed to flow the exact same.
Great video
Just can't beat the look of those GT40 uppers!
There are also industrial GT40 uppers out there, which are iron and which lack the EGR passage. But if I ever get ahold of one, I'll figure out a way to make it work on my Mustang.
Marine application.
Brings memories my 85 mustang GT .. fastest and most fuel efficient car I've owned. With all the mods
Ah lastly back then a new cobra w/o leather was $22,600 with leather 23700. I traded in a “demo” 93 Lightning (HORRIBLE gas mileage even for a car guy). Bought the demo Lightning with 5500 miles for $18000. Dang
Thank you very interesting! Very useful information I needed for my foxbody build. I am Not sure if you saw these videos and I assure you it’s not a joke and I would love to hear your input. There’s a few videos where people are installing ls heads on ford engines. One was ls heads on a 351 Windsor, and theirs some on a ford inline 6! You should check it out it’s very intriguing. Very interested in the ls heads on the ford inline 6 that should have great results.
Yes I have
Man I miss the thunderbird man it brought back memories of that!!
Rich, any idea of what those heads flow and their valve size. Maybe ballpark compression ratio? Great test. The elbow question is finally put to bed.
A good added feature could be a list of the parts showing the HP differences at the end
Tubular: 364.8hp/377.5tq
SN95: 356hp/366tq
Foxbody: 361hp/376.7tq
Explorer 90°: 348hp/373tq
No elbow: 354hp/375tq
KB elbow: 361hp/375tq
I recommend that people never look at just peak numbers-it tells you very little
@@richardholdener1727 100%, but with a test like this where manifolds are so close throughout, it helps. Either way, love the video like always!
Thank you for making this video. I saw an old magazine article that had the GT40, Cobra, and Explorer and they were all around the same hp. Do you have a baseline with the stock h.o. intake?
Richard, I bought your book "5.0L Ford Dyno Tests." I'm sure the royalty check is on its way.
Richard has a video out now, showing the stock H.O. efi upper, and lower, intake, being about 18 to 20 Hp down on this engine combo.
Good, more sbf content
SBF content! 👍
Good video.
I’d love to see a video on intercooler piping size testing. I’m curious under boost how the piping size has an effect. Does bigger piping help an engine that makes 700-800 hp? Is 2.5” too small for that kind of power level?
I second this basic logic says less power but how much less smaller piping is much easier to run
I'm guessing a performer air gap and carb would have put out better numbers
Would have been interesting to see what a standard stock 5.0 GT/LX Fi intake would have done.
that video is up-it was down 18-20 hp to the GT-40
I used the 5.0 stock tb spacer with the get disabled and water out. This on an exploder intake. I think the additional plenum volume could make some difference. Hence your good elbow result.
plenum volume changes very little
@@richardholdener1727 Definitely not gonna argue man, you'd know better than I. The stock spacer sure ain't no billet elbow, that's for sure.
I'm going from an explorer intake with a ported lower and no elbow to a edelbrock performer rpm2 intake. hoping the edelbrock is a good piece cause I was very happy with the explorer intake.
4k n up that RPM2 intake will be Awesome!
Thanks to the Coyote, as much as I love sbf, they have become a thing of the past. For the money I will spend rebuilding a 8.2 deck or a 351, I can have a 1000hp factory sealed reliable daily driven Coyote.
Would be cool to one day see a test of the power difference between a ported lower vs stock on a gt40 intake.
Would pickup about 20-30, depending who ported it.
Porting just the lower is NOT the way to go, as the upper is more of a restriction. The lower is much easier to port, this is why most porter's rec. the customer to do only the lowers,= they, the porters can charge alot of $ for minimal time, and effort. Big dog's porting will port the uppers, and lowers, plus the spacers, th. Bodys, headers, all for really great prices!
It would’ve been interesting to see what spacers between the upper and lower intakes do.
they add runner length-but I would like to test to show what it does
And also the EGR/throttle body spacer on explorer intake.
Could you do comparison of intakes after a extrude honing on each =)
I have a 331 with the E cam, Trick Flow Twisted Wedge heads, 75mm throttle body, Explorer intake, long tube headers. The compression ratio works out to be 9.6 to 1. But it only makes 240 horsepower at the rear wheels
should be higher-is it an auto?
@@richardholdener1727 It has an AOD out of an 86 Lincoln. I did put larger exhaust on it after the dyno run.
@@1murder99 Although you would pick up Hp., if you had Big dogs fully stage 2 port your upper, and lower Explorer intake, along with running 1.72 scorpion endurance roller rockers for your 331,= prob. pick up 40+ wheel Hp!? The 240Hp to the wheels through aod trans., is about 70Hp, more than a stock aod 5.0 H.O.
Maybe I'm spit balling but this motor could benefit from a larger throttle body, period. Your previous talks with head flow and cam lift and duration with the given engine displacement makes me think the 65mm throttle is getting to the point of being small.
it is too small
We need to see a cast 93 cobra intake with the 1” added to the plenum (not phenolic spacer ) . I have cut a few apart to weld in the spacer to add volume and aid in upper rpm performance
I RAN THOSE BACK IN THE DAY
@@richardholdener1727 do you think it was worth the effort?
what about the 5.8 truck manifolds?
Can you test the truck intakes vs the gt40 and maybe the edlebrock truck intake? I have one for my 86 f150 and am super curious if i should try and sell it and swap to a car intake!
If you can wait a while for it, send your intake to Big Dogs Porting. They do great work at a good price, but the wait times can be a while.
Actually surprised to see the 90° elbow isn't all that restrictive.
I wonder how the stock rubber tube type Fox 90* elbow hurts. Gotta get around that shock tower.... Always makes me wonder about the 93Bird, 94-5 swept intake. 🤔
Man for $600 you can't go wrong with the explorer engine!!!!!
The tbird I ran the gt 40 cast iron man for a man on a budget that's the way to go
🔔😎
Would have liked to see an overlay of the tubular and Explorer no elbow. THIS seems to be most likely comparison into a Fox.
Curious of the TBird/SN95 HO upper. 🤔🤔
Thanks for sharing👍👍👍😎
THOUGHT I SHOWED THAT
@@richardholdener1727
Don't see an overlay. But that's fine thank you for the graphs👍👍👍🇺🇸😎
I would like to see what kind of numbers that engine would produce with the Holley high ram and Holley EFI
That would be nice to see.
I was wondering if you can do an episode that continues this comparison with the new Holley 351W HI-Ram EFI Manifold with a 95mm and a 102mm?
plan to test the Hi Ram
Always wondered why no one ever reproduced these intakes with plastic. Cost efficient, cooler AITs, could sell high volumes ..
Could anyone provide an explanation? Also with the 2000 cobra r intakes. Or even utilize 5.0 HO style intakes of tried and true design re-engineered to work on 4.6 SOHC and DOHC designs?
There was a couple companies...such as comp... who did plastic box uppers which were ok but tend to pop under boost. Over the years plastic does deteriorate....but other than weight savings it would have little affect overall.
Honestly it would have just been nice to have seen the factory throttle body from the Ford explorer which is a 70 mm instead of a 60 or 65 mm!! The 70 mm makes a big difference of horsepower and the air to fuel mixture ratio!! Not really hardly much of a comparison when the explorer comes factory with the 70 mm throttle body!? 👌🤷🤯😮💨
Sweet video. Mine is the first and last intake. Did u use the fel pro 1250 intake gaskets? Also be cool to do a test with a truck intake
these heads require 1262s
@@richardholdener1727 ok, thank you for letting me know
It would've been nice to see what a 1" spacer would effect.
Would take away 7HP, and give about 7 ft. pound in torque
@@FXRSDriver Based on?
@@bradmason5204 I road race a Mustang for an amateur endurance series. We must run stock intakes. No tubular. Cobra, Explorer or GT only. Here is my results from 8 hours of tuning with a stock cam, stock exhaust mini tube headers with no cats on completely stock GT40p heads and 1.72 roller rockers. We also ran a Cobra lower and Explorer lower. All runs done with an Explorer TB converted for Fox linkage and cable. All results at the wheels with Cobra crank pulley with P.S. and Alternator only. Fuel was 93 octane. 13.0 AFR with 13 degrees initial timing and a custom chip. We did not use the Explorer elbow. Hope this helps.
1. 95 Cobra upper and lower 261hp
2. 99 Explorer upper and lower 258hp
3. 91 Thunderbird upper and lower 257hp
4. 90 Mustang GT upper and lower 252hp
5. Explorer upper Cobra lower 252hp.
All Torque outputs were within 4 ft/lbs for all 5 combinations. All the spacer does with these combinations is move the power curve down in the rpm range with no real gains in either Tq. or hp. More cam is needed to help a spacer work.
@@dohcsmr1175 NASA CMC?
@@bradmason5204 Champ Car, AER, WRL. Ran A Sedan SCCA for years. A Sedan spec out a 600 CFM carb and an Edlebrock intake with Big Porting of GT40 heads. Now they use Edlebrock heads. That was a fun class. A lot more money but a fun class.
The stock SN95 throttle body which was used is 60mm
yes, 58MM technically but you can round up
Man I wish you could do a 351w truck intake, stock ported & edelbrock with some heads & cam for us truck guys
planned
I’m all ears
how do these do vs a truck manifold? no one ever mentions much about the truck manifolds
GT40, Eddelbrock & Trick Flow are the GO TO pushrod 5.0 intakes.
Never was a fan of the explorer intake.
add the Holly Systemax 2 to that list and that basically covers it.
Run a test on one of bigdogs performance stage 3 gt40 or modded f150 intakes.
like to
Richard, I think I’ve watched all of your Ford 5.0 intake and cylinder head comparison videos and I’d love to see or even your valuable opinion regarding the the stock intake manifolds and the Edelbrock Pro Flo 4 intake manifold. I believe my car has some ECU issues and I’m thinking about an upgrade to the Edelbrock Pro Flo 4 EFI. Thank you for your technical videos.
IF YOU ARE TALKING ABOUT THE SINGLE-PLANE EFI INTAKE-NOT A GOOD CHOICE
@@richardholdener1727 What would be the best choice on intake manifold? I’m planning to use the AFR heads and a street HR cam, 210/215 @050. Thank you for your advices.
A lower port job on a GT-40 tube manifold was worth 30hp at the wheels.
An unported Systemmax was worth 10 over that.
30 hp from porting the lower? with the stock tubes and a 65mm throttle body?
@@richardholdener1727 it was a very aggressive port job. So much so that it had oil control issues due to thin walls and the addition of a heat shield.
This was on a 9.5 :1 306 with as cast AFR 165 s and a 70mm tb. I was running an E303 at the time with 1.7s. And equal length shorty headers
There are two different Explorer intakes and the Early one is better than the late one.
The non ho was a set point 19 lbs injectors a mustang lx computer speed density explorer cam that exceeds the max 444 lift and gt 40 explorer intake upgraded fuel pump stock e6 heads wide open exhaust ripped good but had a high idle? 88 crown vic with a 87 nose what a shame some a hole poured diesel in my tank and screwed me I was pissed!
I'm looking for a vid or info on a base line 5.0L mustang with a 225 hp and doing a GT40 heads and intake swap. What are the relative gains and is it worth the money? My son has an 87' convertible we would like to add a little kick to it.
I have a video where I installed a GT-40 intake, I have another vid where I installed GT-40 pr heads, the combo would give you 50 hp or so-better with a cam
What's your best guess of using a edelbrock performer intake and a holley 600 cfm carb. I have a 95 5.0 ,.030, with an E303 cam and GT40p heads with upgraded springs and 1.6 roller rockers . For me anything in the mid- 300s would be awesome in my 55 F100. All things being equal could I add about 30hp to your test sample?
YOUR P HEADS WOULD BE WAY DOWN COMPARED TO THESE BPE CNC HEADS
Just for S&G's wish you would have thrown a Trick Flow upper on it.
I have TFS top end vids up
I had really good power with the GT40 intake, but I got even more power with the Edelbrock and the Edelbrock made the most power for me. The Edelbrock beat every other intake I tried. I used a 70mm throttle body. The GT40 intake just about as good as most of the other aftermarket intakes. Magic 5.0 camshaft I use is Crower 15511, which makes more power than the next larger Crower camshaft and equals the Ford 220/.498"/110 camshaft for power. Two Crower cam sizes up for a 331 stroker though. For me the GT40 intake was about as good as the Trick Flow intake, but the Edelbrock beat all of them. The Trick Flow valve springs are good, as is the Trick Flow stage two camshaft, if changing pistons. Both the Crower and Ford cams beat the Trick Flow stage one cam, but the stage two camshaft beat all of them, but requires piston clearance.
Which edelbrock intake are you talking about here the performer or the rpm
@@brettkelly1436 The RPM. I didn't know Edelbrock made a smaller one.
They used to make a lower RPM version just called the Performer, as opposed to Performer RPM. No longer in production I think.
the RPM II is very good-but trades power like the SysteMax-the GT-40 is not close to power of either of those, nor does it make what a TFS Street Heat or Burner intake does
@@richardholdener1727 There was another one we tried and I think it was "II" version of the Holley Systemax (Systemax II). It was better than the GT40, but not as good as the RPM. Holley made a smaller Systemax version too, that wasn't very good at power, even compared to the GT40.
So I’m planning on building a fox body with a 408w. I have a trickflow R with the 90mm tb opening. It’s NOT the box one. Will this intake work well with a 408? It’s a street/strip car. I will be using TW 11R heads, and that 236 cam for strokers. I can always swap to the box R, but I’m scared it won’t fit under a 2.5 cowl hood!
THE BOX MAKES MORE POWER THAN THE R-THAT VID IS UP I BELIEVE
Was the throttle body off a 94 -95 cobra? I believe there a 60 mm and the GT was 56 mm. So that would explain why it drop off over the whole RPM range vs an 65 mm.
the SN95 didn't get a 65 unfortunately
Gotta have techno when watching your timelasps hope all is good Richard the live streams are still my favorite videos 👍👍
I don't know about you, but I have always had to run a spacer on my upper intake. Also, the inlet tube has a 90 on it between the TB & the MAF. Isn't that pretty much standard on all Fox Stangs?
the air intake tube does have a 90-we ran open TB
I'm just now starting to build my 94 mustang and I have a few questions. Do you have a recommended street build list?
look at the vids and pick a power level
Why not test the Holley High Ram intake? It may not be cheap, but it would be nice to see how much HP it's worth to just have it on there... Thanks for the video Richard! Friggin awesome! 5.0 is not dead yet lol
Im also wondering why not truck intakes were tested ot the edelbrock truck intake?
this was only GT-40 related
I "know a guy" with a Hi Ram on a 363 in a boosted application. It works very well...4 digit hp at the wheels. You have to have cubes or rpm, or both, to make it work it seems.
@@ericmuhlbeier8023 I have the bones of a 94 cobra engine in my 1990 f150 using the truck intake with a port match....Runs REALLY good with stock computer....I have not dynoed this engine, but I woud estimate between 260 and 270 rwhp...
@@billbrons8993 i picked up an edelbrock truck intake from a local wrecking yard for 75 bucks. I plan to install it on my stock 5.0 in my 86 f150.. but have been contemplating scooping up an explorer gt40 roller core and going through it and putting some sort of cam in it.. unsure which one to use at this point.. the truck will get a zf5 speed at that time ( already have it ready) it has 4.10s and 33s so low end torque really isn't a priority
Richard, have you ever done a direct comparison between the Holley Systemax II and the Edelbrock Performer RPM II on a normally aspirated 302? Thank you!
no sir-should be similar
@@richardholdener1727 thank you! Love your videos!
I watch all off these tests, and think it's great. I've never commented on anything, but I have to ask about the torque curve dip early in the run? Obviously it doesn't have to do with the upper intake. Is it heads or lower intake? Just curious.
it's a function of the load in
@@richardholdener1727 not the initial load in, the mid range is what I'm asking about. It is very slight, I've had engines do this. And have always been curious about the mid range "slouch" I'll call it.
We've noticed that smaller primary headers and better scavenging makes quite a difference in the mid range. Lots of variables that might not duplicate in a vehicle
@@hotrodray6802 Mine has a tq dip at ~3750 that wouldn't tune out...GT40/Ford shorty's.
@@alexbrown4820 I know what you’re talking about if you ever watch LS Dyno tests a lot of times you’ll see almost a double torque peak or you’ll see that dip in the mid range and from what I understand that’s a function of the runner length of the manifold
if you look at some of the different runner length Dyno Tests you’ll see that certain runner lengths will take that out but it actually ends up having a dip elsewhere in the curve I’m not sure if you are completely able to tune that out
Should have tested a Bigdogs Porting Stage 2 and Stage 3 ported 93 Cobra gt40 manifold. the results would have SHOCKED you!!!!
tested lots of those back in the day
@@richardholdener1727 not one from us. Bing difference especially when they are flow tested to flow more than the Systemax 2 and Victor 5.0s. One of our ported Cobra gt40 manifolds made 30whp more than a ported Edelbrock rpm. We posted the video and dyno results. We have yet to see anyone do that shootout because that's what most people do. They don't put bone stock gt40 type manifolds on
I have question is more efficient to running a good size turbo or running two small twin turbos on a v6 or v8 engines
same if they are sized for the power
