Wastegate Explained.

[speed2horizon]

hi all, i'm new to car modification. I was looking for a shop that can offer a good workmanship on welding & mounting the 2 wastegates for my 6A12TT engine. Which shop would you recommend. I don't mind paying a bit higher as long as the work quality is good. Please help TQ

if u're at somewhere ard sunway n usj, u might opt for ah heng exhaust. If u're somewhere ard batucaves, the jian hang would be a good choice. I'm more close to jian hang. Good workmanship.

I live in greenwood area. I think jian hang would be the closest. But jian hang location can you roughly describe bro?

By the way, for twin turbo, we gonna have two hose connected to the 2 wastegate right. which hose we choose to be connected to the boost controller for bleeding?

I want to clarify on the boost controller purpose. The solenoid there in the pic is the one who bleed the pressure to the internal wastegate actuator rite? This solenoid controlled by the boost controller module in the car. but where do we connect the vacumm/pressure hose from boost controller module? This hose is to let the controller know what is the actual boost reading rite? and it adjust the solenoid to bleed more or to close the valve. y vacumm also we can connect?

Anywhere along the Intercooler piping.

When boost(aka positive pressure) involve, it has to be in open throttle position. So, the intake manifold would also be pressurized.

If I put after intercooler before throttle body, when the throttle butterfly closes, the pressure in the pipe still maintain untill BOV bleed it out. When i put in the throttle body, when the buterfly closes, the pressure will be vacumm. will it do any harm to the controller?

Dun worry la.. it's just a map sensor...

It only reads pressure...

Hi taiko !! Long time not chat
MERRY CHRISMAS !!!!!!!!!!!!!!!!!!!!!!! :cheers:
Taiko wanna ask you...
Most people modify their MAF piping from air filter to turbo is it follow the turbo inlet diameter ??
For example : Turbo inlet diameter is 2.5"... that means the piping should put 2.5" to air filter ??
And the turbo inlet diameter to intercooler is 2" only...then must follow their size same as ??

No need... For Intake ramp, turbo to MAF, inlet follow the MAF diameter. The reduce gradually to the turbo inlet size...

For turbo to intercooler, use according to ic inlet size. From ic outlet, follow the size... Going up to the intake manifold, expand to TB size.

Go JIAN HANG/AH HENG, they'll know wad to do.

Hehe!!ok!!thanks taiko!! Jian hang at where ? They got do install turbo ?? Coz i plan to go Torque Gear opposite Links dyno...any advice ?

Jian hang only do piping ma.... Where got dyno dyno all....
At Sri Gombak there.

oic.... coz i need to rechange turbocharger...
btw thanks ! taiko !!

Y..? T28 not shiok..?

 

[veilsideboyz]

Haha..not la ~~
I havent Install turbo yet...
Next year 2010 only start my project :D
Because..have to know the whole piping have to change or not...
Ok ! I will follow your advice ! Thanks !!
MAF -->Turbo is 2.7" (MAF inlet diameter is 2.7")
Turbo-->IC is 2" (IC inlet only 2")
IC-->TB is 2.7" (My Throttle body is 3"..i think inlet only 2.7")
Taiko ~! What I know is...
If using standalone can go for 3" piping...
If using piggyback..better stay for 2.5" to 2.7" right ?
hope can help ~

Not abt wad management u using. It's wad u want ur setup to be. How much power u expecting from the mods. How much flow ur turbo is generating in terms of volume/secs. Bigger piping diameter does cause flow to be more even. But it also require more time to fill in the bigger volume to produce positive pressure/boost.

Management is just a control system of ur engine. And ofcourse, sequential ignition does provide a more consistent exhaust flow.. Thus improve the response of the engine n flow.

the intercooler piping 2.5 inch back tb 3 inch is normal for 1.8cc turbocharger engine,i never hear the air flow intake piping must be follow by turbo inlet size?that is really stupid word,why you got so many super sin+lan friend?the td05h evo123 inlet only got 2.1 inch like that why the air flow sensor hose is 3 inch?make sense please.....

Haha~~dont know ler...my fren around all also sin+lan ler
Chriss..last time I still remember you told me before..But I can't find the post :rolleyes:
Intercooler to throttle body better stay at 2.5 right ?
I think My T28 turbo inlet also around 2.1" like that.. Ok~I think I will make the MAF piping from 2.5" to 2.1" TC...
Thanks !:wavey:

the air flow sensor pipe u wanna put 3 inch also does't matter,the near throttle body that last piping better get 3inc, if u got stand alone ecu like micro tech motec,u don want that air flow sensor pipe also can,just direct suck air~

Ok~Thanks !!

Check out your compressor inlet at garrett website. Compare with GT2560. They are almost the same. at least all the flanges are the same...

Errmm... Chriss, I think I said that... But what I meant was follow the MAF diameter/size then reduce gradually till the turbo inlet size. So that the air can flow smoothly into the compressor inlet. If u don't reduce gradually and allow sudden contraction where the compressor inlet is, then there'll be a compression head loss. Maybe u won;t feel it when u drive, but it can be proven on dyno and fluid dynamics calculation.

But if going to do it, why don't do the right way..? 1 time work ma...

Last piping segment is done according to the TB inlet size to match the inlet port size. Yes, direct suck air gives the best response. Sounds good too... Damn 7 yeng too... Maybe VSB likes it. But ur throttlebody maintenance should be more frequent.

Make sure put a net to avoid big pieces going into ur compressor. And tie a net tightly with hose clamp or cable tie. Suction of compressor cound suck the net in and damage ur compressor wheel, then your throttlebody. If the broken pieces enters the engine, it could also cause harm to your turbine wheel..

One otai kena before... Lolz.... DUn ask who...

 

[veilsideboyz]

I think I have to rechange the whole piping.... Now my whole piping all 2"... WTF !! My original TB already 2.7"... BUT THE PIPING SMALLER THAN OEM !!!!!!!!!!
Anyway..thanks guys !! :(
