R34 Plazmaman Plenums Hp Out Put?

[dsrturbo]

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

get a life and go read the rb25det dyno results thread

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.

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

[dsrturbo]

ive done a full search threw the posts and theres only a couple of plaz pleums showing small power. Nothing seen there with over 350 400+

Thanks for comments tho

[R31Nismoid]

You could always ring them...

[PM-R33]

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?

[R31Nismoid]

^ 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

Ah ok well then that makes a lot more sense.

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
