R34 Plazmaman Plenums Hp Out Put?

[Lukas 33]

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

Yes catalytic Converter. Ah ok no cat....hmmmm. Have you tried seeing if it makes more power when you disconnect the exhaust from where the cat used to be? How bad is the pressure drop over the intercooler?

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?

96 octane... are you from America or similar?

Hub not equal to rwkw. You take the wheels off mate

275 on a HUB @ 8psi sounds about right however for a GT35. Anyway, that's not the main issue here!

If the timing is not correct mate, you can have issues making power, most certainly.

Shell and Caltex in NZ is 96 Octane. We have Gull and thats 98 Octane. But is over 1 hours drive away.. We were running up on 96 and then doing a final tune on 98. But never got that far.

definately not the plenum...possibly the plenum install if there is a leak...

how is boost through the pull? does it stay constant or drop off a fair bit?

droping the exhaust for a run is the best idea as is doesn't really cost you anything and can rule out a component.

you'd also want to have the cams dialed in as they are a fairly important part of an engine and can see a range of differing results... which cams have you got?

I have 1 Tomei exhaust cam gear. Im hopeful that changing this will do something. Also the plenum, i removed yesterday and have purchased a new gasket to rule that out. The Exhaust tip is a oem nismo er34 unit and has a restrictor in it. A Small Armour All Spray bottle it to fat to poke up it. I think its 2.25" Diameter. But still pressure test was 2psi so.. Will suggest losining off the exhaust front pipe

Gasket is two weeks off from nissan nz / jp. Some bit of a wait ;/

If the tip is 2.25", then what size internal DI is the muffler? Sounds like the problem at this stage.

Simple and fast to drop it dump-back anyhow

[dsrturbo]

Im hopeful we will get everything sorted by next time round. Here are a few pictures now taken of the exhaust "3" and what not.

Bit of a over dose with Silicone on the plenum..

I will take care of the silencer pictured by taking it to an engineer to saw off the tip. Remove the silencer. Take out a pcs of the silencer. Pop it back in. Weld the tip back on and after alot of $ will be good as new

Ok um...but what cams do you have. As in what camshafts 2.25" is bloody small! I think my exhaust is going to be too small for the 25/30 with a gt35r so 2.25 is pretty small. I know you say the pressure test said 2psi but I still think you should just drop the exhaust and measure the power output. Please

Fuel system? Pump? lines? pressure tested @ [given psi]?. What rail you using? are the injectors maxing out? is it IW or Ex?

Not he fuel pump and Injectors. Have a inside fuel guage ( greddy thing ) Tomei pump sard 800 or 850cc injectors. Maybe there Denzo.

Cams are Pon cams. Will see what happens second time round. 2 weeks away

[joeyjoejoejuniorshabadoo]

less than 3" is too small and nismo exhausts are shit... drop it and see what happens
