screemer pipe

[woking rob]

does any1 no how this works? is it aloud on the road? they sound wickid and ur turbo spools up alot quicker does any1 make one for a t5 or have i gotta custom make one?

hi,

they sound awesome, very loud... they work by letting the over pressure gases out to atmosphere direct through the screamer pipe, usually that stuff goes back into the exhaust bypassing the turbo and you of course dont hear it... I had one fitted to an EVO very impressive noise, but can be a pain as it is LOUD all the time when expressing over-pressure..

as for is it allowed, well depends on local plod, most of the time people wont hear it cos it only happens when you "on it" in town it wont work unless you a complete nutter!!!

I haven't hear any for volvo, not really a volvo thing, but would be interesting, you could make one, or get one made i guess.. have a youtube link, search http://www.youtube.com/watch?v=yxAgK81anrI not the best but you can get an idea...

how does it only work on full throttle?

how does it only work on full throttle?

only works once your on full boost , you will need a custom manifold , exhaust ans a external wastegte , and turbo unless you weld shut the wastegate port on your turbo shut

am thinkin about 1 for mine

You can do it a cheapy way but I wouldn't recommend it.
You need to seperate where the exhaust comes out from the turbine and where it's "Dumped" from the wastegate. eBay sell special turbo elbows (For the 200SX that I've seen) that have seperate outlets, But the bit that sits between the ports can let by gases and it'll just sound like you have no exhaust (Like that slow looking Evo above, LOL) Chances of you finding one to fit the Volvo are slim anyway.

This one sounds okay though...

That skyline has chronic turbo lag - would be better with just a decent straight through exhaust on IMHO.

Will still be pretty damn loud with a straight through and de-cat anyway.

Yeah, Gotta remember this is a big turbo'd Jap car, Not a small turbo'd Swede ;)
Didn't sound like he was anywhere near the limiter either.

These ones are better...

And here's the elbow I was talking about...

you need to have the external waste atteched before the manifold meets the turbo , then you can run the pipe from the external wastegate either to the atmosphere or back into the exhaust, if your after just gettin the turbo to spool up quicker , you could try bigger intercooler pipe work , pedro has 3inch and his 19t spools as quick as a 15g , but he also has a valve on the down pipe , he will be able to tell you better than me

does that have a valve in it or does it come out that pipe all the time coz the cars i have seen them on have had standard style wastgates not to loud exhaust till they give it beans then all u can hear is boost? and its not like wastgate chatter its just a big woosh of boost as it spools up

yes m8 its shut untill you get to the desinated boost pressure then opens and lets the exces out via a screammer pipe or back into the exhaust , theres a few websites about to help and i thinks theres a few vids on youtube that show how they work

Yum yum now those are pretty tasty - you wouldn't care about the lag if you could do that on boost.

wickid gonna see if i can get one made to come out just behind the front wheel so i can run a bee r limiter so it will pop and bang and spit flams out at the front and back lol

the 3" RIP kit & 960 TB defo made the world of difference to the amount of lag from the 19t. I very rarely open the exhaust bypass valve, thats just for the strip & dyno's lol

a decat will do that

Lot of money though just to get the noise he's after.
The elbow will be cheaper.
