screamer!!

[REBEL GT TURBO]

No im not talking about your mum!
I'm just wondering what all the hype is about this screamer talk? what is it where does it go? i know its something to do with the wastegate/turbo! i want my 5 to be a scremer!

[r5 rich]

put your misses in the passenger seat or a female friend and take her for a hard boosting session round some country road. I`m sure she will more than be screaming then!!

[Shakes]

I had one on my skyline i fooking hated it.
just makes it sound like the exaust is blowing.

[J$£5GTT]

waste of time an effort...

[MADFIVE]

well i must say each to there own ive got one on my 5 and it sounds the boll**cks. and friends tell me they have seen the odd flames spitting out on full boost befour. well worth the work imo.

[J$£5GTT]

there in the same league as d'valves....

ermmmmm no not really! ive never known a screamer pipe to go whooop tsssss. ever.

external=no actuator hardly the same league as a d/v

[J$£5GTT]

what i mean is there not really needed.....

These are fairly good links to explain what it actually is, as nobody has really said yet lol

id have to be proven wrong especially with one fitted to a 5...is it really gna make a whole lot of difference? ,ferrari f40 the yes..

also going to make track days a no go area with noise restrictions.

more noise does not mean more power.

[soapymech]

[Markey Mark (BD)]

Its not all about the noise, its about how well it controls the boost levels.

[MADFIVE]

i agree mark i find that its not so laggy with the external wastegate. it boosts really well. also you dont have to run a efi set up and tubelur manifold for it to work well on a 5. mines been custome fitted to a standerd manifold and it works spot on.

same here iv also noticed smoother gear changes so not so aggresive on the engine mounts.its my lead foot that i cant control

[newbstar*]

Madfive have you ever fitted or owned a car with one. Sure one of the old audis came from factory with them.

[J$£5GTT]

so for a quieter operation how does it effect performance with it going back into the exhaust just before the cat? ie no screamer...

[Tony Walker]

5 doesnt have a cat? going back in to the exhaust after the turbo would work too, and obviously reduce noise.

[Tony Walker]

how are people with screamer pipes installing there wideband sensors?? and monitoring fueling?

i know...but was wondering how and if it effects performance or just chills the noise?

"are not technically for street use."

i love that word

no mate this was my first attempt and i must say it great. a few mates in the past have had them on there evos and 200sxs. just wanted to custome fit one on the 5 and it works so happy days.

[Tony Walker]

dont see why it wouldnt be street legal on a 5, no cat so not increasing emissions, if it re-enters the exhaust system. if it is coming out of a seperate pipe i geuss there would be noise restrictions and placement restrictions? i doubt many mot testers are going to experience it opening anyway

[Rob@Backyardracing]

You can just install the sensor in its normal place on the down pipe or elbow.. The screamer pipe wont effect the Air/ Fuel ratio or readings.. The Burn is the burn so to speak, it will have the same gas mix throughout..

[Tony Walker]

yeah i was thinking that after i wrote it lol.

[Josie172cup]

So where do i get one?

[Markey Mark (BD)]

You have to make an external wastegate fit, no bolt on kit out there

[tubby5]

You don't need an external wastegate,you could get a new down pipe made which separates the penny valve and the exhaust wheel.then you would just have a screamer pipe at the wastegate side
