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

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

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

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.

Thank you so much for doing this video! I’ve always been curious about this!

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)

Love these tests. Really interesting, thank you

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.

This is amazing information and data for all of us. Great job guys

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 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?

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 :(

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.

If only HyperTune replied to emails.

Let’s be realistic though, if your going to 1000hp + then you’re not likely keeping the ITB’s.

Brilliant... Really interesting & not what I was expecting 😲 Bring on the single throttle & I hope (but probably not likely) the Swedish / twin plenum style!!! 😁🥳🤔

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.

Would love to see both the old and new Greddy intake manifolds fitted and tested

Would ya though?

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

Do you plan on switching out the silicone coupler on the intake with a vibrant clamp?

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?

Can't you buy different length runners on that tho and throttle body very interesting tho great sirises

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?
