but does anyone know for sure if screamer pipes are illegal or not in NSW? I know in Victoria their not.

:laugh:

Do you even know what a screamer pipe is? And/or what the Australian Design Rules (which are a Federal law and thus apply in every State and Territory) are with respect to emissions?

doesnt a screamer pipe only loud when the wastegate opens?

so if i were to control my boost... not reving over 4,000 then that my wastegate shouldnt open.... or does it?

btw all new to this turbo side of cars...

On a stock turbo it will "leak" no matter what RPM, and will sound like you have an exhaust leak until it comes on boost when the wastegate fully opens.

also since i have a stock rb25det engine, what good would installing a bigger wastegate to my stock turbo do for me?

Absolutely nothing. There it nothing that installing an External Wastegate will achieve on a stock RB25 turbo.

I honestly think you should forget about this screamer pipe talk...

Also the whole External Wastegate talk... you have what is essentially a stock car.

I would highly reccomend to just go and purchase a Split Dump from BATMBL or someone else who sells them on this forum (check the For Sale/Trader section for this)

i think it wouldnt do me any good anyways because arent the stock turbo's ceramic and can only withstand 12psi max boost before causing any damages?

10psi would be my limit if i had to choose from

My car when it had the Ext Gate.

NOTE: I've never head an internally gated turbo sound even close to this.

So dont expect to get anywhere near what the video shows

cheers

umm isnt this the sound of an external wastegate without a screamer pipe?

sounds good...

*just about to tear my hair out*

The link is my car.

The sound of an External 45mm Turbosmart Wastegate, with a screamer pipe.

Running off a GT30 600hp turbo

A screamer pipe is the metal pipe that plugs into the wastegate.

It is called a screamer because it is venting to the atmoshpere

An External wastegate can be plumbed back into the exhaust and then it no longer has a screamer pipe because exhaust gas from the wastegate now runs through the Catalytic Convertor and then though to the rest of the Exhaust System

I dont have the time to draw you a pic in MSPaint.

If someone else does then maybe that will make you understand.

I seriously suggest to go to this website and please READ what is on there

well im actually planning after installing the screamer pipe

a 3.5" turbo back exhaust system

so i guess i have to put up with the sound of an exhaust leak for a bit

but its not like i drive my car everyday tho... weekend only

but how bad will this sound like on my stock system?

R31Nismoid... do you know what it sounds like???

also i am going to install the screamer soon... cause ive recently got it custom made

just curious of what people have experienced from these things

seriously stuff the screamer pipe unless ur gonna get an externally gates turbo like a gt30 + they all sound like rat shit, not havin a go but i heard plenty of internal gated screamers and external gated screamers and there is a big difference in sounds...i like my screamer on my car but i have a td07s with a 45mm ex. gate running 20psi my mate has one on a stock turbo and i wont go there on how it sounds

ben...

it will sound like SHIT on your stock system

take some proper advice

*pics up hair and sticks on own head*

so R31Nismoid... can I make this screamer pipe make flutter noises bro?

:)

ps - don't ban me.. :laugh:

I was simply asking the next question for the man. :P

I can describe the sound of a screamer pipe on stock turbo.

Get one of your mates.

feed him large plate of baked beans.

after about 2 hours, when he feels his stomache expand and make noises slowly traveling down his stomach to his ass, quickly lie on the floor on your side, with your left or right ear facing up towards the ceiling, get your mate to pull his pants down, undies too... get him to press his hairy arsehole to your upward pointing ear...

then tell him to let it rip!!!

there you have it..

screamer pipe off stock turbo, stock wastegate.

NOTE: Tell your friend to try and not follow through and shit all up side your head.

The thing i always find it funny on here is people say, "its federal law, and its illegal" but how many people's car break the laws here, or break the laws in their cars.. i dont think anyone could say they dont.

I think a screamer with an externally gated turbo sounds awesome.. Suprises a few people with a stealth exhaust on...

An internally gated turbo with a screamer pipe from my experiences sounds like a strangling cat... a HHHHHHAAAAAAAAAAAAAAAAAAAAA sound... like when you hear a car with a really quiet exhaust getting up it... just a lot of air out of a pipe sound.

If you want to hear a video, search for the video HKS Twin Turbo Supra VS. Nissan 240sx.mpg on kazaa, the supra has one... bear in mind that car probably has 800+hp.. but gives you an idea how loud it is... haha its hallariously loud. The thing to bear in mind when you have a really loud car as well, is that police will hear you from ages away, which might sound cool, but you're always treading on eggshells when you get up it in the city, or anywhere for that matter

R31Nismoid, let him go and do whatever stupid thing he wants to do, only way it seems for some people to learn...often after about 3 failed attempts as well...

Im done trying to help in this thread :dry:

R31Nismoid - dude - your car sounds sick :P so angry :P

Cheers. You get over it though, trust me.

That was the old setup however :O

i know the fines 10k for no cat but what is the fine for a screamer? i have mine set up with a flange so i can easily have it on or off coz i luv the sound but dont look forward to the fines even though it is very hard to see it, so yeh anyone know the exact fine for them

ben...

Its exactly the same. You are venting exhaust gasses to the atmosphere unmuffled and not using a catalytic converter. You could put a muffler and cat on a screamer pipe and it would be perfectly legal.

aquariuz6, are you after the choof-choof-choof-choof noise when you come off the throttle rather than blow off valve noise? From your posts thats what im guessing as you dont seem to comprehend what a screamer pipe actually is (not to mention asked if you can run a BOV when you have installed your screamer pipe??), and alot of people think a ''wastegate'' makes the choof-choof-choof-choof noise.

    • You're not wrong, but more than a few times I've heard of people running into issues where their injector characterization isn't quite right and that approach works for that specific configuration but once they switch over to a new set they discover a whole bunch of stuff wasn't set up correctly. It's slightly more annoying to reverse engineer the OEM MAF transfer function but you already have the sensor wired up to the factory harness so keeping it around for a few weeks more while you figure out the tune is easy enough. I've seen GM also use a combination of both MAF + MAP in their ECUs before, MAF is for steady state and a calculation of the cylinder VE to correct the base VE table, then in transients it uses that calculated VE + raw MAP to determine cylinder filling somehow.
    • I know this one’s the BB one. My tuner did make mention about the actuator. I am curious about the VCT as well
    • Might also needs a stronger actuator with the right preloading. With older 2019 built bush G3 units, BB upgrade or 21U housing down size makes a pretty decent gain in response as well. 
    • Hey lads  so im finally putting together my rb30 forged bottom end and ran into an issue. I measured my main bearing clearance with arp main studs torqued to 60 ft-lbs using ACL H series STD size bearings and standard, un-ground crank shaft journals and got an oil clearance reading of about 1.3 thou measuring straight up and down and about 2.8 thou measuring at a 45 degree angle (just above and below the parting line). My machine shop said they measured the main tunnel and it was all within spec (they didnt say the actual measurement) and to go with a standard size bearing, which i have done and the clearance is too tight, I'm guessing because of the extra clamping force from the arp studs distorting the main tunnel. I was wanting to run about 2.5 thou main bearing clearance.  My questions are: 1. could i just use the HX extra 1 thou clearance ACL bearings? that would fix my straight up and down clearance making it about 2.3 thou, but then would the side to side clearance be too big at around 3.8 thou? 2. what actually is the recommended main bearing clearance for measuring near the parting line / side to side. i know its supposed to be bigger as the bearing has some eccentricity built into it but how much more clearance should there be compared to the straight up and down measurement? at the moment there is about 1.5thou difference, is that acceptable or should it be less? 3. If i took the engine block + girdle back to the machine shop and got them to line bore the main tunnel (like i told them to do the first time, but they said it didnt need it) what bearing size would i buy? the STD size bearing shells already slide in fairly easily with no real resistance, some even falling out if i tip the girdle up-side-down. If im taking material out of the main tunnel would i need a bearing with extra material on the back side to make up for it? this is probably confusing af to read so if something doesn't make sense let me know and ill try explaining in a different way. My machine shop doesn't come back from christmas break until mid January, hence why i'm asking these questions here. TIA for any help or info 
    • I bought the model back in Japan in Feb. I realised I could never build it, looked around for people who could build it, turns out there's some very skilled people out there that will make copies of 1:1 cars or near enough. I'm not really a photo guy... but people were dragging me in a group chat for the choice of bumper as someone else saw the car before it was finished as they are also a customer of that shop. I took the photo in the above post because I was pretty confident that the lip would work wonders for it. Here's some more in-progress and almost-done pics. It gives a good enough idea as to what the rear looks like!   I have also booked in a track day at the end of January. Lets all hope that is nothing but pure fun and games. If it's not pure fun and games, well, I've already got half an engine spare in the cupboard
