Amazing to see that something as old as the NISMO plenum is STILL the king for the street car, after all these years.
Millions of dollars spent in R&D by NISMO.... hard to beat.
I don't even have an RB or GTR but still find these videos really interesting, would be great to see comparisons for all sorts of parts in the future. Looks like the NISMO inlet manifold is the best for your car in its current state.
Same as me, I have old BMW’s but I will say a lot of the info and tips can be applied to any car/engine if you take it for what it is.
I love these tech videos! I am slowly building an R33 GTR and this is pure gold!!!
Great to see that for 2.5x the factory power, the Nismo one, which just bolts on, with OE TB's is still perfectly adequate. Incredible really
Great test, good information! Very informative! Very interesting results. The Nismo Inlet is really well designed.
This is amazing information and data for all of us. Great job guys
Thank you so much for doing this video! I’ve always been curious about this!
Wish you tested the Greddy, if the hyper tune showed zero gain at almost 800 whp, what difference would it make at 1200 hp, 10 more? Lol
Love these tests. Really interesting, thank you
Great video as always Andrew! Really looking forward to seeing what the results are for the G45/48mm throttles versus g45/single throttle. Keep up the great work 👌
Always wanted to see these tested, great work !
\
Great series Andrew - Been doing the very same job on my car and was really wanting to buy hypertune with single throttle body - now staying with stock!
Awesome work 🔥
Scotlaaaaand friend lol lanark
I seriously love This project. Pls more. first comment btw
Great work on being first….
Love your tests Andrew.!!! I hope you test the Hypertune manifold against the Nismo one when you fit the bigger turbo. REALLY interested to see how that all goes even in terms of driveability etc..... . I'm guessing the driveability will fall away ever so slightly.!!??? In the real world, in my mind, you have the perfect street car/set up NOW.!! R32GTR is, and has been for ever, my favourite car. If I win big in powerball I'm coming knocking on your door. 😊👍👍
Love seeing these comparisons videos
Back in 2008-2012 when I used to build RB’s here in the States the only reason we used the greedy intake manifold was because we mainly dealt with RB25’s. We just did it to clean up the inlet piping, any performance gain we made was just a plus. I think the RB25’s was where the greedy manifolds shined IMO. They were WAY BETTER then the 25’s manifolds lol
I was not a fan of the Greddy manifold on my 25. Like he said in the video it killed the midrange power and it was way too peaky fro my liking.
The roll racing clips were Awesome! 👍
Lol the Greddy absolutely has bellmouth runners, and unlike the hypertune they aren’t raised which would cause turbulence, especially by the time air gets to the last runners. Also Greddy has great volume over stock/hypertune. Do the test on the Greddy and prove the hypertune is better 😁 You practically told us at the start of the video you don’t wanna upset your business partners 🤣
I don't believe it was done in malice to misguide anyone or pander to partners as such (might be but who knows) but more so as the finer details of the Greddy being missed, plus it being discontinued are factors- it's pretty unlikely a discontinued Greddy plenum, even if it performs better- would impact Hypertune's sales.
It'd be interesting to know if the non-raised bellmouths are possibly even better than the Nismo raised counterparts as the airflow is much less turbulent when the surface leading into each runner is more predictable, smooth and overall faster.
It probably is close to the Nismo, better than Hypertune and better than OEM at their power level currently. Would be a good test, and they really should do it before switching the setup or enlarging the ITBs on the car.....
@@masonc1010 the raised bellmouths give a very small percentage advantage over a radius on the floor but raised helps air distribution between the 6, I don't think raised vs not would make a whole lot of difference though. If they had more or a radius on the bell in the plenum, longer runner with a taper down to the throttle bodies it might be a lot more different.
But the greddy being a cast finish might not be a bad thing, depending on how an engine is used depends on the port surface finish, slightly rougher will keep a thicker boundary layer and possibly keep fuel suspended. So it might be better for street duties. Annoying to do but it would be an interesting comparison.
The single throttle body manifold test will be there interesting one because the itb's are no longer a restriction ad disruption of the wave action in the runner.
Agreed. I run one, and its absolutely HUGE when its actually in the engine bay. I too think that the Greddy would do a better job then the Hypertune POS(Yes, no typo). I sanded down the inside of the runners before I put it on. I also sanded the exterior and had it professionaly painted gloss black. It flies under the radar all the time as people think its the stock intake :D
Love these type of videos so interesting!
Great test. And as always. More runner lenght = More better.
Glad someone finally put a hypertune back/to/back. Just goes to show the OEM's still know a thing or 2😊
Japanese engineers have to be up there with the smartest dudes on the planet. Hard to go against them
Brilliant... Really interesting & not what I was expecting 😲
Bring on the single throttle & I hope (but probably not likely) the Swedish / twin plenum style!!! 😁🥳🤔
Good to see some honest information
This helps confirm what I've been researching on my side. Goleby had a similar test for JZ motors and had similar results, a lot less down low but on the JZ it did provide top end on a 500hp motor. So for response, stick with OEM, or make longer runners to try and improve the bottom end torque, as 25mm is well too short.
As an Owner of an RB26 that was clearly modified in the 90's and then forgotten about, before being imported to the USA, that has the old Greddy Intake Manifold. I can confirm that it appears to have been used on a massive turbo car for more top end powa! Disappointed to hear that it's not as good as the others. But really really enjoyed learning about it. Thank you very much!
Love this. Very interesting 🤙👍
Would of loved to see the Greddy dyno. I have one sitting on my shelf deciding if I should throw it on before the tune. :(
omg been waiting for this
Great video thanks 🙏🏻 👍🏻💥
Would love to see both the old and new Greddy intake manifolds fitted and tested
great video very helpful
The Greddy does have a 'bellmouth' design, however no raised pieces are evident which is why it seems that they don't exist. But they are certainly there, and the casting is noticeably smoother than stock/OEM (although nothing crazy- still a difference)
Although it's discontinued, there is still a pumping market for older or discontinued JDM parts, Greddy manifolds included.
It would be a really good idea to test the Greddy before changing the setup on the car to tell exactly how much difference there is. It's likely better than OEM, better than Hypertune and comparable or slightly below Nismo at the power level of the car currently.
i personally switched from Greddy to Hypertune with single throttlebody, happy with the results the gains and throttle response is much better but again the build on G42-1450 making about 1k hp on dyno
How you get the intake manifold ? Wanted to know if you had any issues with hypertune before ? Been trying to Reach Peter but no luck :(
You should have included to the bellmouth tip on your Hypertune and Nismo runner measurement
The hypertune obviously cant scavenge. Put your hand over the plug when you drain the bath, thats whats happening inside the runner for viewers learning about this, its happening in the exhaust too. Also the GReddy does have a bellmouth, its not 360 deg, but its half there cast into the backplate.
A hit with the flap wheel and the GReddy might beat the hypertune 🍻 👍
I flowed my Greddy with a flap wheel ,plenty of room for improvement over stock greddy , and also far easier when you need to take the plenum of to work on that side of motor as you can leave all the main hoses on, and intercooler pipe fits nice .
I have garage Ito 50mm itb's. I then machined my Greddy backplate out to 50mm as deep as I dare without breaking through where the bolts go and then took the air tool's to the rest to blend it all out. A lot of work can be done to the Greddy, such a shame it's discontinued for those who haven't got one. Bolting then on standard I can see what he's saying but who would? That's why it's split, so you can pest up the inside. We all love the mods.
@@boaboc5898 I have seen Chinese copies available for a fraction of the price. They look identical. Its only a casting after all, so great value.
Since the plenum on this engine is pre-throttle, could you feasibly run a positive pressure idle for instant throttle response similar to the reactivity of a supercharger?
Definitely the throttle body gonna do justice. I have a j35 v6 .. my plenum opens up after 72 mm and k tuner
love the honesty.
Motive is THE automotive source.
Do you plan on switching out the silicone coupler on the intake with a vibrant clamp?
you’ll be surprised how good the greddy is. the nismo is too close too the stock, the greddy, Due too the volume the 6xTB LOVE having the EXTRA air on demand,
I bet it works better than the nismo.
The two piece design makes accessing all the spaghetti underneath a breeze compared too all out there
(i have run both BTW)
you really needed to test the greddy cast one, there is a new greddy ss one you can still buy today
You guys are like the gamers Nexus of the automotive world.
Can't you buy different length runners on that tho and throttle body very interesting tho great sirises
what about the new greddy alloy ones, have they got velocity stacks in them now versus the old cast alloy greddy ones
Would be nice to see a cheap chinese made inlet manifold tested as well, something like the Otaku Garage or Aeroflow style manifolds
If only HyperTune replied to emails.
Going by the test, no point. It's more expensive, harder to install, and going by the dyno plot it's behind the Nismo one from start to finish and actually probably doesn't have a lot over the stock one aside from the fact that the airflow to cylinders may be more even
@@misterlith weren't you listening? He said Hypertune themselves say it's designed for well over 1000hp. That's when there would be a point.
@@imaginova88 I was listening. That is hypothetical, and assuming they're using aftermarket throttles. When using the stock throttle diameter it's not going to make a difference if it's a bigger setup
@@misterlith it’s behind the stock inlet, the Nismo comparison would have been a larger difference.
I been trying to Reach him for weeks now 😢
Hey bro have use ever tried a dual chamber/plane intake manifold to balance air into each cylinder ? Are they good
I would love to see the results between a hypertune with single tb and nismo itbs, and then Nismo with oversize 49mm itbs :)
The greddy design is the most different out of the lot, its strange that it wasn’t tested.
Came down to $$$
If this video gets - million views, we will test it
Would it not be useful to put those 48mm throttle bodies on before putting the g45 on to really see the comparison?
Yeah you can say all you want but without testing it it doesn't mean shit
Will you be doing vs a single throttle body too?
Nismo really did their r&d well back in the day then
I would like to see if hypertune have optional 50mm or 75mm itb runner for this setup and redo the dyno run with longer runner...
On 4age, 25mm vs 50 vs 75 vs 100mm runner, the 100mm give the best overall, while 75mm favour higher rpm while giving low down plenty of torque...
I would say for gtr, 75mm runner could be the ideal runner length for best overall maybe?
Need to see Plazmaman results
100% agreed. Just installed a Plazmaman
Missed opportunity. Should have at least tested the GReddy rather than just guessed it wouldn't be any good and then fitted the shiny plenum from Hypertune. The whole point of the GReddy plenum is that you can get in there and port and polish it smooth and radius everything. You bloody need to because they're pretty roughly cast. I don't know how you're measuring volume but I measured the OEM plenum at 3750cc and a standard GReddy plenum at 5750cc. The GReddy port matched and fully smoothed throughout went up to 6750cc. Also measured the runners as being a little longer than the OEM plenum. All the idle control stuff fits under the GReddy plenum. its main disadvantage is its heavy and the seal is a potential failure point.
That greddy does look like it has plenty of space to add in some bell-mouths and increase runner length if one simply has one available.
It has them already- they're just not raised like the Nismo ones. Have a closer inspection and they're certainly 'bellmouth designed' runners. Not exactly a true bellmouth, but a tapered inlet nonetheless
@@masonc1010 The radiused junctions are certainly better than straight, but flow wise are still quite a bit off a full raised bell-mouth. It's subjective of course, but I don't call those bell-mouths.
@@captainobvious9188 Agreed. 'Bellmouth designed' is how I worded it because they're not quite there- but agreed again certainly better than nothing.
should have tested the long runner Hypertune one.
Test the plazmaman pls Hawkins
This channel makes me wanna RB swop by TT.
Would ya though?
Man this all makes me feel so intimidated for when my r32 arrives. But I’m prepared for it all. Only thing I’m scared to do is touch the bodywork. I’ve only ever worked with the internals smh
You American? Just let rip woth the credit card mate.
@@sexyfacenation Dominican American yep. But I’m doing this all myself. Start to finish. No credit card needed. Just hard work and a bunch of elbow grease lol
Bodywork is only rhe hardest shit to deal with! Good luck bro.
Runner length is key. Current shinny short runner trend makes me sad
BILLLET!!!!
Preach. Also love your work especially the Hilux and the PZJ70 😍
This man knows his shit.
Surely the lack of a specially cast/machined bellmouth isn't much difference to the well smoothed over transition from the plenum to the runners in the greddy? As long as there is no sharp edges I didn't think the addition of a belmouth that actually adds a sharp outside edge on the lip (only really seen in the nismo I admit) would be any different. If anything I would have thought that the uneven inside surface caused by the belmouths would cause more turbulence within the manifold than having a simple smooth casting transition like seen in the greddy, which has pretty much the same radius on the opening of the runners that is seen on most aftermarket belmouths
Due to weird air stuff im not even going to pretend to understand, bellmouths have repeatadly been proven to have better airflow (presumably due to less turbulence?)
Whether theres a major difference between boosted or n\a plenums though, im not sure, as ive only seen comparison's for N\A applications.
@@Klutchylol as long as their is a radius on the entrance to the runner you will have all the benefit you need. Having that radius project past the flange that the runners enter from should not provide any benefit, and in some billet manifolds you can see that the radius is simply the edge of the runner and only covers a 90 degree angle before blending into the wall of the manifold
@@lockjawjak weird air stuff exists mate. Bellmouths work better than radiuses
Seemed to be a lot of ‘Pandering’ to the hypertune brand to offset it’s lack of performance for the price paid. Let’s be realistic though, if your going to 1000hp + then you’re not likely keeping the ITB’s.
At this point I would say that Hypertune have banked on the ‘Looks’ taking precedence and if they say it’s Designed for applications over 1000hp then where do they say their products benefits are seen?
Unless you're going to DBW, why would you ditch the ITBs? You can easily wring 4-digit power numbers out of these throttles.
What would you say is better than Hypertune in your opinion?
ITB tuning sucks. It’s so much easier to tune a single throttle vs 6. Also think of cross sectional interference of all 6 throttles blocking flow into the engine vs a single throttle.
@@deciplesteve you can but there are plenty of benefits of going a single DBW on applications for over 1k hp
@@deegan463 based on this video alone you could say the stock intake.
Hey can you guys please test the standard plenum vs aftermarket in terms of the rear cylinders running lean ?? And what boost it starts to happen at ???
We already did
@@MotiveVideo oh thanks maybe I missed it
Eyeball engineering.
Sauce for the intro song?
what exhaust were you running here ? mufler , 3inch -4 inch ?
4-inch
Weights?
Are there differences with a single throttle compared to the individual throttles?
yes. Very much so. Which will we compare once we have G45 on
Put little air flaps higher each port so each one can literally Catch the air.
The new Greddy is what should be tested imo - new design, readily available, well worth a test.
Havent seen a single one in Australia
@@MotiveVideo guessing that has something to do with locally available options 🤷🏼♂️ it's a really nice piece, I wish I had gotten to do back to back testing on mine with it(the OEM ITB version) vs OEM but only got a few drives in before losing a ring and now rebuilding and changing other stuff too 😢
💥💥💥
Love the videos keep up the great work
Sounds like a waste of money unless you have over 1000bhp
So Stock works way better! By far!
You guys should do a Freddy vs Greddy vs Stock inlet for RB 25s for us poor people that can’t afford a GTR 😂
test the greedy, just countersunk bellmouths, this is just a pretty piece... might not come "into its own" untill 14 15 but what kind of consolation is that lol I reckon the nismo and greedy will probably still do better right accross the board port an polish the greedy for the 48mm comparision and slaughter the hypertune
Anyone else pissed that they didn't test the greddy... Dude used an eye Dyno to discredit it ..like and comment please! Maybe they will re think this missed opportunity
Even of throttle and off boost the turbo is still spinning so theoretically filling it up maybe not as quick of w.o.t
But thing logically your on boost turbo spinning forcing air slam the throttle shut pressure goes up due to the fact turbo was spooling and air has now nowhere to go
Wish there was a love button, so I could smash that
"the data doesn't lie"
Why don’t you get them on a flow bench they don’t lie with the results and way faster to test different manifolds
👍
Came here for the Greddy lol
I hope the hypertune is the best otherwise I'm going to cry
Ok now I'm crying
@@AdmissionGaming lol
Haha
Foreal man ... Test the greddy .. you were wrong about the hypertune ... You might have been wrong about the greedy!
Wheres the Buildoff Content?
I bet the Greddy would have worked better than the Hypertune. Mustn’t upset the sponsors though 🙄
Maatouks use hypertune all day long but most of their builds are up there
Test the Greddy.
Transfer us $2000 and we will. Also it’s discontinued so pointless.
Just seems unfair. You can’t “test” 3 manifolds without all 3 physically undergoing testing. Just saying
@@Russianrybakov We cant afford day labour, fabrication work and dyno time for every manifold. it has cost us 10K so far to test NIsmo and Hypertune to make back $400 on CZcams. Why test a discontinued inlet?
hypertune lol... is very very nice and all, but i cant see how its worth the money compared to stock for most peoples setups, and id buy a proven japanese brand over something handmade for even more money that doesnt seem to make a difference anyway
Where are these “proven” japanese brands and their results?
@@MotiveVideo Hypertune uses DMG Mori CNC machines... a proven Japanese brand. and according to your own test the Nismo beat the fingerprint magnet Hyperpos.
Laminar flow. Turbulent flow.
still like to see a not polished comparison. Or golf ball like indents.
Gold ball indents have never ever worked in an engine
It's a shame you didn't try the Greedy. You could have split it open smoothed down the casting marks and then run it. I think it would surprise you how good it is. I was toying with buying a Chinese copy for £200 and port in myself so was interested to see. But you bailed on it. 😒
We simply cant afford it to be honest
every manifold swap and custom fab cost money
Wow so about 4k out of pocket and all the extra labour for less power and less low end torque..
This sort of talk makes me think my 600hp rb26 is 150hp 🤣🤣🤣
I take it as there was no drivability summary it’s worse to drive also than the nismo. So I conclude from this if your sticking with throttle bodies go Nismo, hypertune is over rated.
Hypercrying
Hahahah HYPERJUNK ! Overpriced parts that don't work. Your pretty welds don't take the fact away that there is no gain over a standard 30 year old nissan manifold.
i think the best way to actually test these is the butt dyno, its all how it feels at the end of the day.
Most people’s butt dynos are wrong
the fuel numbers dont lie about what changes do, same with track times
So not a comparison video. Not testing. Fake vid
Except for the comparison and the testing 🤦♂️
