Usefulness of wastegate

[AsianBookie]

Mind telling me what is the use of a wastegate and does it directly increase power?? :emoticon_U:

 

[rollakid]

hmm? i thought wastegate is to bypass exhaust gas so your car won't go overpower or overboost? more like limiting the power for the health of your turbo rather than increase power.

dun quote me on that, i'm no turbo user.

 

[alvin24]

wastegate doesn't increase power... just increases turbo response, and is more stabilized limiting boost.

STock torbo's also got internal wastegate... most aftermarket turbos don't have internal wastegate... which requires you to purchase and install an external wastegate.

 

[Fluffy]

yup..its to bypass the turbine to control the amount of boost to be produced by the compressor.

alvin24: issit all aftermarket turbo dun have the wastegate?
how many wastegates i need in a turbo?
like the bigger the turbo is, i need more wastegate??

 

[Dino@Casper]

U only need one wastegate

 

[BLaCkHoWLiNG]

dino: really? but i've got 2?

 

[Dino@Casper]

okay i should repharse it than.. haha depending on how much exhaust need to be release in order to prevent overboost some cars might need more than 1... hehe normally use 1 only... maaf bang maaf, or more accurately twin turbo engine.. so could use to wastegate.. correct now?

 

[BLaCkHoWLiNG]

eheheheh....dunno la.... i put 2nd unit jes for show.. heheheheheh

 

[Dino@Casper]

Haha.. so can anyone clear the mess up.. cause its logical if you have twin turbo's maybe u need 2 wastegate..

 

[Fluffy]

one for one la.haha but blackie..arent u running on a single?:_:

 

[BLaCkHoWLiNG]

i'm running single



go do a search on why pple need 2 wastegates and u'll know :)

 

[AsianBookie]

so wastegate is to increases turbo response, as far as i know from this thread

some say only 1 wastegate is enough, some say 2..

but y?

BLaCkHoWLiNG mind to explain?

 

[Fluffy]

not really response..but the amount of preassure(boost).

 

[rollakid]

louder wastegate sound? sure syok.. scare those around you

 

[Fluffy]

hahah im still trying to get the info..but cant find any..

 

[alvin24]

Choice of wastegate is dependent on turbo size... the bigger the turbo, the bigger the wastegate needed.

I can't figure out a reason for using 2 wastegates... unless blackie's monster use single wastegate oso the exhaust gas can't come out fast enuff... therefore need 2 ?? hahahaha...

 

[Fluffy]

ahah yeah..i dont see the reason to have two.

to eliminate very frequent boost spikes?

 

[xerofighter]

then whats the difference between an internal and an external wastegate?

 

[jeffblazed]

put 2 wastegate will sound....... prap,prap

put 2 bov will sound .......pissssss,pissssss

so a car with 4 of this stuff will sound prap,prap pissss.pisssss, every time u change gear.........

 

[Fluffy]

xero : the internal one is comes already with the turbo unit itself..the external one is..outside.

external

internal

 

[Fluffy]

jeff : wat?are u for real?

 

[BLaCkHoWLiNG]

fluff: imagine u have a twin brother.. .at the same EXACT instance, both of u shout WOI! ... so will u hear 2 wois or 1 loud woi...

 

[boggysv]

blackie, how often do people get to boost as high as you on such a big engine ler?

 

[AsianBookie]

fluff: imagine u have a twin brother.. .at the same EXACT instance, both of u shout WOI! ... so will u hear 2 wois or 1 loud woi...

black: so when u change gear, the sound is woi woi?
2 sounds issit, but issit possbile
what advantage u get from it?

 

[alvin24]

Difference between internal and external wastegate? One's inside, the other's outside... wahahaha... =Þ do a google search on photos then u'll know what they look like lor...

asianbookie,
blackie already said 'At the EXACT instance'... still u can come up with 'woi woi' ?!? hahaha... =Þ Wonder what will happen when one of the wastegate not tuned as tight as the other... or maybe one side wastegate rosak liau... the one will 'woi' earlier than the other... hahahaha.
"wooooowoooooooooooooiiiiiiiioooooooiiiiii"
Waahahahah
