No tune on any of the dyno runs that have been done on the new 3.0tt, nissan is under rating them just like they did with the gtr engine...last i heard the 400hp model was pulling close to 450whp stock

Yep, thats what I said when I saw that Q run a 12.8 with AWD. These turbos, both 300 and 400hp variants are sandbagged.

I have been playing with the idea of trading my base model in for a 2016 red nismo brand new for $37,500. I may just wait.

Only FI prototype cbe. Down pipes being added and running again.

this is from the q50?

Yes Tony has one of every flavor (engine wise) at least of the V6 for now maybe a 2.0 I honestly can't remember.

Already has a FI cbe and down pipe set up built for them they are currently dyno testing them today.

The cbe alone gained 46wtq under 4K rpms that's awesome. I think "peak" was mid 30wtq at 5k

I know it's blurry I had tony relay the numbers.

Lower down pipes and cbe.....

393hp/390tq

:drool:

Can't wait to see the Z35!

I wonder what numbers I'll be able to get without touching the cats, sort of want to leave those stock this time around. What are they tuning with? Does Uprev or Ecutek have some software for it already?

The three runs on that sheet are stock, cbe, and cbe + dp

can't see the 3 runs

My bad forgot to post it.

Hard to make out, is that 383whp 373 wtrq with the CBE? Slap some header son there and more developed tuning software for this new platform and 400whp should be doable with stock cats. I'll need to ask Seb about this. No wonder why he's been too busy to change my tranny fluid.

I wanna know how much power something like a 3"-4" straight exhaust would make on the turbo set up. :yum:

I know nothing about how turbo systems work, but can't we just add a boost controller to up the boost?

Also IIRC, Stillen dyno'd a Q50S 400 a couple months ago & got 375WHP 350WTQ; on point with Specialty Z's dynojet.

I know it is a different system but I know the MR16DDT in the Juke does not like boost controllers and better off having a series of tunes via the cruise control buttons to control the boost and a bit more stable to boot.

That's a nice flat torque curve. If they offer that in the next Z, Nissan, take my money please.

IIRC stillen was mentioning a true dual CBE would actually drop power due to the size of the engine and not enough back pressure or whatever...

interesting to see what a different set up tubes and combo of tubes proves on the dyno.

:iagree:

That statement makes no sense based on it being a boosted setup. You want no back pressure with turbos. NA and supercharger setups want the back pressure.

Plus with how quiet turbos make a car I'd be tempted to run just open down pipes haha power and noise :yum:

this was taken from infinit50.org or whatever and was a stillen post in regards to a dual 3'' cbe

We are almost done with our new exhaust specifically for the Q50 TT. There is definitely a big restriction in the Cats. The Primary doesn't have a huge pipe diameter restriction, but the secondary necks down to 1.5 inches. I can't say how your setup will sound, but there is really no reason to do a 3inch dual setup. The engine and turbos aren't big enough to make sure of it and it might just hurt power.

My son bigger is always better lol

But yes new engine and setup and they are smaller turbos but still the more air you put in and pump out then it'll gain with boost.

Sort of -- it's a matter of having air or exhaust mass appropriately matching the volume of the relevant chambers (including within the engine) it flows through for optimal intake, combustion, and exhaust (which varies according to load...).

Too big a diameter for the mass means the speed will slow down, too little and it will backup (i.e., "back pressure"). This will vary enormously with RPM and even more so when boost is involved (valve overlap and timing come into play here too, BTW).

With a turbo, usually the "bigger piping the better" rule holds primarily because the turbo itself restricts exhaust flow, but just going bigger isn't necessarily the solution. Something that just smooths out flow (i.e., minimizes existing restrictions) without massive changes in tubing diameter will probably make a world of difference alone, which is what those dynos suggest.

Also, if they keep VVEL on this motor, it should play a much greater role in tuning FI than it has for NA. The rate at which AF mixture is drawn in, combusted and then expelled to turn the turbine of the turbo will be critical to optimal power and responsiveness, and there will be more wiggle room to play with potentially.

The most flexible way to do that would be tuning valve timing and overlap since a purely mechanical change will be fixed and require some compromise to achieve best output across the rev range.

Judging from that dyno, Nissan did a good job making the twin turbos offer high performance practically right off idle.

Now if you with a bigger set of turbos in the mix (or a gigantic single turbo), then yes, you may need bigger piping.

OEM, my guess is that one turbo is dedicated to bottom end torque and the other to top end, and they balanced the transition so well, the torque curve is reminiscent of a roots blower's output.

Anyway, I want :yum:

Is there a link to that video?

Nissan ditched vvel for this engine according to stillens blog on their website.

no VVEL on the VR30 :) it's responding good to the mods ;)

That's just stupid:driving:

Hopefully the Z will look good. I don't like the Mazda 6 they turned the G into.

But those headlights and eyebrows......

Oh, and it is now a Q:icon17:

Really. Hmm. Well, only the intake cam could be dialed anyway. I figured they might go for fully controllable intake and exhaust cam. Oh well. I think that VVEL system added a whole lot of extra heat in the head and was a pain to tune, so probably for the best.

Is any aspect of valve timing tunable or all fixed?

NVM, I founds it https://www.instagram.com/p/BJtcyoihy2n/?hl=en

So this is with no tuning, just adding the bolt-ons. Can't wait to see what they can do when tuning software for this engine is out.

there is variable cam timing just no variable valve lift :) once software is out i have no doubt there will be at least another 50whp to be gained from a proper re-flash.

I like this Q50 review cuz it gives some detail on the engine performance.

I'm really looking forward to the tuning potential of the VR30DDTT. I'm strongly considering consolidating cars and picking up a Q50 red after the mid-model refresh.

Damn. We're looking at the likelihood of a 3.0TT Z that has a 0-60 around 4.4 sec out of the box, and plenty of room to get faster :yum:

Damn it, Nissan! Release the Valkyries already!

With an extra 400lbs taken off, lsd and lower COG. I think we're looking at 4.1

Sooooo with just a little intake/exhaust/tune and stickier tires we could be sub 4 sec 0-60......

Excuse me I need some alone time.
