HELP!!! WASTEGATE No Sound!!!

[contreasjun27]

guys i just install a brand new wastegate..
eh replica tial 38mm...
but no sound coming out from the wastegate at all..
there is no leaking in the piping or anyway else...
when i boost...0.9 no problem, boost maintains...
ask my foremen to check my turbine housing there whether the actuator is seal properly and he said yes...sigh

I was told that if my wastegate not working I will get overboost...
help ppl dont know whats the problem that making the wastegate no sound sigh

whats the diameter of the wastepipe from wastegate?

There is a high boost and low boost control on your wastegate. Remove top vacum hose and only maintain the bottom vacum hose with boost controller or fishbone.

hey bro, everything ok?
try to get smaller pipe size like 30mm pipe, for sure scream like mad lol

thru experience, this is wht i can say

mitsu housings are poor in reliability unless its a evo3 n up which has more nikel content

its prone to crack at the turbine housing especially the WGA flapper side

i would say, fit in the hose directly without tulang ikan n see if it opens up

if it opens up then this is wht happened
your tulang ikan is giving the wastegate pressure to open up , bt since it hasnt reached the boost levels yet, it is leaking from other source , BOV , pipings , intake or etc , chck on that

another simplest way, the hose tht goes to ur wastegate, remove it totally
BEWARE dont WOT like a mad guy hehehehhe jun oh jun
take the car for a slow ride, see if it boost up to 0.9bar or does it shoot more
if it still sits on 0.9bar err there is a problem here , BOOST LEAK

ok bro i will try to take out the tulang ikan and try 1st..
the 2nd way...i dont really understand..
i dont connect the hose to wastegate...then should i put in my tulang ikan back???

jinkl, some foremen ask me to potong the spring say maybe the spring is too hard...
do you agree of doing so?

if spring is too hard, it should overboost bro

jin..it's not the lack of nickel content in Mitsu housings that crack..it's the design on the inlet volute area.

even the Evo 3 or even Evo 4-5-6-7- all cracks ! somehow the concentration of gasses peak at the area where the wastegate flapper is.

 

[rakesh_v6]

wouldnt it be coz of replica ?

ops okie, because we triend porting out the vr4rs housing n the evo3 housing, we damaged our grinder doing the evo3, according to org org dsm , they are crazy bout the e3 manifold n turbine housings cos they said nickel content :D

could be a sales gimmick, bt its all over the dsm forums

well..porting helps but it doesn't solve the fact of the design.. anyway.. forums will be forums..

wht to do , learning is a never ending process

no worries..

if spring is too hard, it should overboost bro

so is it a good idea to but the spring?
now i know is 1 bar spring..
if cut 1 loop out is around 0.8-0.7 right?

 

[chrissyong]

abit kampung spec but it work~

 

[jinkl]

actually cutting the spring gonna make more probs
solve the issue first i guess bro

if the wastegate has no sound, means its not opening at all , IT WILL make sound if it opens up due to dumping to atmo
which also means u should be overboosting, bt in this case u r not passing 0.9bar

its a diffrent prob here, its a leak
do a boost leak test

i sent my ride to ATS racing in sunway the shop facing the loji...
they say no leaking...after doing a few testing bro...
coz when there is leak i cant really boost high right jin..
but i can boost till 0.9 no problem only got misfire only haha

yeah but jin say more problem if cut spring..
haih headache lah me...
