Hello,

I'm interested to know from anyone that has or knows of people running a R34 Plazmaman Plenum with after market ECU and Turbo " 3540 " Etc

Anyone here making over 300 - 400 RWKW From Plazmaman R34 Plenum? Or have Dyno reports

Thank you

The plazmaman plenums are rated at something like 800HP-1000HP of air flow aren't they? So i doubt they would be a resctriction of any sort if that's what you are asking.

get a life and go read the rb25det dyno results thread

What on earth is up with this comment??? Seems "reading your previous posts" your not a happy guy.

Has anyone actually made over 3-400KW with this Plenum?

Well you can make that much power on the factory one mate... so you would very much hope an aftermarket one would do the same now wouldn't you? :(

But yeah, you could just read the dyno results thread. Look at the part list... then look at the power made... you then answer your question with a bit of your own self help :D

I'm confused, what are you actually worried about? It not flowing enough air to support that power? As Ash said, the stock one can flow that much power, so one twice the size obviously will.

These plenums are capable of flowing 1000+ HP. Not only will you experience instant power gains , but you will have the capability to maximize future modifications .

Quote from Plazmamans site.

The plenum isn't going to be a problem anywhere near those power levels.

I have a er34gtt with pon cams, pistons, exhaust gear, rods, link g4,ross balancer, plazma plenum, 3540.82 turbo. 70 pound springs.

At 8psi car makes 275 rwkw. Increase the boost to 17ponds it makes 285kw..

Weve done pressure tests in Exhuast and intercooler and cant figure out why it wont make power. Today i tested the valve springs and none of them are spungy -all fine at 70+ pounds.

I need to rule out the plenum and to do that im asking t see a 400kw or less er34gtt.

Car should make 330+ Kw at 14psi and 380+ at 19 pounds. As our partners cars have with the same turbo using a er33 engine.

Maybe r34 just cant make power.

Next to do is the following:

1. Dial in the exhaust cam.

2. Backpressure test the exhaust manifold/turbo inlet to determine ratio of inlet/exhaust.

You are expecting to get 380+rwkw from a GT35R with a 0.82 rear? Is this a Rb25/30 or just an RB25?

Same turbo on r33gtst engine is making 330 at 14psi. Using a r32 Computer and 300zx air flow meter and de cam shafts. Hub Dyno. Same Dyno, same tuner

Even at 17 pounds Engine should be making more power than 285. Its only 10kw difference and yet 9psi Increase.

Above comments Is next to do

I think that .82 housing is going to stop you from making 380rwkw, but we shall see. Back to your original problem.

The plenum isn't the problem. You got any dyno graphs you could show us?

When you say you tested the exhaust and intercooler, did you drop the exhaust at the dump/cat to test that?

^ hub dyno's is not RWKW mate. Lukas - that is why he is higher than normal.

If boost goes up, power does not = exhaust restriction most of the time.

Have you even dropped the exhaust from the dump/front pipe and seen what happens? (im dubious of this "pressure" testing you've done when its as simple as 3 bolts)

Are you 100% sure the cam/gears are all dialled in correctly?

Yeh dont take the exhaust off at the turbo and test haha. I also think that the 0.82 will restrict you from that power level. Are you 100% sure they aren't running a 1.06 rear housing or something? Have you checked that your cat hasn't collapsed?

We put a pressure tester in the oxygen sensor hole and did a run. The result was 2psi. Could be better but that is not the problem

Piston Compression test no not yet. Possible cause. But i asked Tuner and he sai unlikly. CP and pauta rods. Will test tho next run ( no smoke or problems - tuner would pick up ? )

huh? I was just wondering if the cat had collapsed. hahaha sorry if you thought I meant do a compression test.

Cam gears dialed in will be done next. However tuner has asked other tuners advice and they say if car makes 275 on 96 octane at 8psi. It should have no trouble making more power dialed or not. Im pretty sure the dynaPack Dyno is in rear wheel kw. I will have to ask about this?

Cat like catconverta? It has no cat it has been removed. VT has been turn off and on with no significant difference

Right now its a odd ball. Because alot of money has been spent on te engine to only make 275kw :D

      Cheers. Skyline is back on the menu, can’t get rid of it. It’s like a child you don’t want, or herpes

      I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.

      Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days

      It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
