香港都有二手播，點解要日本bid番黎...

古惑強

Ok to bid for it at low low price, you never know you may get lucky!  Don't know whether it comes with manual or not, it would be quite difficult to setup without the manual.

Simon

好似放血咁.
啱啱個心理先調整左去bid TRD彈弓, 即刻又黎水喉掣... 好想呀....

Anybody interested?

Simon

應該如此...
個水喉掣唔係全密封, 雖然波子頂住個底, 但可以過氣, 而過氣的程度, 就等如個wastegate本身的却壓bar 數.
所以, 當時應該等如由turbo出壓力直駁wastegate無分別.

古惑強

有趣，要諗一諗！不過行親無限叭會好難揸同好窒，因為部偈會Misfire到暈，一起叭就會砰砰聲Cut-out到儍！

Simon

想想吓, 如果我掉轉左氣喉, 無野輸入去推開wastegate, 我應該有無限叭喎.
力量就好似有無限叭, 不過個bar錶都只係出0.5bar.
有d唔明添.要再唸唸

There is other type would be a Pressure Bleed Valve, provide that your factory EBV is still working properly, you can install the PBV along the pipe to the turbo actuator, and then set the PBV to raise the base boost from 0.5 bar to 0.6 bar, while retaining the control effect of the factory EBV.

我果個cheap cheap水喉掣，攪左好耐都set得吾好，早排駁番原裝個ebv，又開心番晒，其實實際上水喉掣可以超壓之外，可吾可以減lag呢？

I don't think it can help to reduce turbo lag, as the turbo still requires the same rpm to generate the same boost as before, but I guess it would instead improve the spool up time as the 水喉掣 does help to keep the turbine spinning almost all the time.  But we do lost all modulation from the factory standard EBV.

古惑強

上返叭、係咪開心晒呢！

16v turbo 行 Max 1.0 ~ 1.1 bar左右。 唔好貪心呀！

Simon

之前得0.5bar完來駁錯喉.
turbo出壓力喉同wastegate喉掉轉左.
現在bar數有0.9bar.

Simon

Patrick, 你啱. 空踩都會起bar.

我都估空波俾油夠廢氣推郁個turbo就會起bar...吾係點解有Ｄ車空波呼油都會有放氣嘩佬聲？

Adrian....Back in Black! Look forward to it.

Only if Adrian come out this week. Have heard that many times before.

Thanks Adrian!

唔明喎。乜原裝個 EBV 會做左咁多野？ 咁即係話換左機械式水喉掣 Off 波比油都會起 Bar?

Interesting, I never try that but I guess it should!

From my very limited understanding, the on-board computer is supposed to monitor the throttle position angle, engine rpm, engine load, air pressure (16v)/ air flow (20v), water / oil temperature and the preset mappings to determine the frequency of the switching of EBV, in order to achieve an in between boost level from base boost up until max boost.  Now replaced by a 機械式水喉掣, it has only 1 input parameter which is the built-up air pressure within the inlet manifold pipe, and until it reaches the pre-set limit (max-boost), then pressurized air will be let through the 機械式水喉掣 and push open the wastegate.

...因為機械式水喉掣係完全冇晒油門角度做 modulation ，因為就算係輕腳油門，個 wastage 都係完全關到實，所有死氣係去晒推個渦輪...

不過因為無入油, 殺左一半就鳴金收兵.
