i got a external waste gate witha screamer but because of the yellow sticker i have put it into the exhauts but i kinda feels like the power is not the same is there any reason for this ??

was it tuned with the screamer ? maybe piping the screamer into the exhaust may have changed the a/f ratios at the oxygen sensor ? or it may just be the fact that screamer pipes offer a massive horsepower gain over going traditional that you can now feel the loss

Because they exhaust you have isnt good enough :/

Ie, not free flowing…

You need a proper, decent system if you want to plumb-back and not have issues

Tune isnt really the reason for it, its the added restriction

man doesn't matter how much you pay for somethin.. that doesn't make it good...

if it feels doughy then it's because it's been made restrictive a screamer pipe will produce the same power as a properly designed exhaust no drama's what so ever. I work for an exhaust company and talked to the engineers about this several times... It's all down to the design

the system is a little under $2200 so i think it is good enough i was thinkin it could just be the flow and the tuning cos it was tuned with the screamer

Well, sorry to say... but for $2200 it clearly isnt good enough, otherwise there would be no performance loss at all.

Nothing to do with it "tuned" with the screamer, its after the turbo... therefore tune changes wont affect it.

Its being caused by pressure build up, which is a poor flowing exhaust first and foremost.

its the plecebo *spelling* effect man...

if u think it ''feels'' less powerful it will feel like that.

HENCE- if u have a decent exhaust and have mounted the pipe WITH the exhaust flow u will be FINE.

u probably are used to the sound

SOUND DOESNT EQUAL POWAH

If your exhaust is free flowing, you will not loose any power going from screamer back to exhaust pipe returned.

I'm sure it doesn't SOUND nearly as fast though :blink:

+1

When i had my first car laser tx3 4wd, i had a screamer pipe for 2 years from my wastegate, then i had it plumbed back into the exhaust & it did feel like it had less power slightly, but when on the dyno it made roughly exactly the same power as with the pipe plumbed back.

    • Hi all,   long time listener, first time caller   i was wondering if anyone can help me identify a transistor on the climate control unit board that decided to fry itself   I've circled it in the attached photo   any help would be appreciated
    • I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!
    • I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.
    • The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.
    • No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
