otai2 4g9x Skalian..boleh bagi pendapat? apa clucth set sesuai utk flyweel ori 4g91???

4g91 flywheel 8 inci... kalau mo sedap kasi upgrade flywheel mivec to 8.5 inch.. kalau masih stendet flywheel buleh pakai oem exedy clutch set... kalu mo sedap pakai semi racing exedy clutch set.. hehehe

Boleh pakai clucth set perdana kah?

clutch set perdana brapa inci? kalau 9 inci, flywheel pun kena 9 inci..
baru ngam.. tapi masa masuk di g/box x muat.. dlm g/box kene kasi skim supaya itu clutch set bule masuk kalau 9 inci punya set laa.....

akhir nya saya pakai clutch proton 1.6 juga harap2 tdk sleeeep hheheh

saya pakai 8" flywheel..gearbox mau skim sikit sebab saya pakai 1.3 punya gearbox..ok jgalah..

bila mau tgk gbox auto ko nie...? mmg mau auto nie bro....

tidak tau lah kalau kamu urg faham pasal penggunaan oversize flywheel and clutch. Tiada guna pasang oversize flywheel/clutch kalau HP kurang 30% dari original HP. Lagi besar flywheel, lagi susah & berat mau pusing. Last2 tertinggal di belakang, baru mau mengejar. Lepas tu bising minyak tinggi. Lepas-lepas tu inner CV joint pecah, gearbox syncromesh bising dan macam2 lah.

Just get better clutch compound & better clutch cover. Cukup suda.

ringan, mungkin. tapi tiada apa-apakah crankshaft kalau guna berat yang lain? takut crankshaft lari balance.

ada mahu tanya, macam mana mahu adjust mixture fuel lean or rich? sebab kereta saya ini rich mixture walaupun sudah warming up.

There is two way you can adjust your Air Fuel Ratio, with Adjustable Fuel Regulator or piggyback and the best is using both of it.

AFR - you can trim the fuel supply by manual adjustment on the Fuel regulator.
Piggyback - You can tune with precise calculation on your fuel injectors, ignition control, & others point of tuning with the support of digital interference on your factory ECU.

The best way to tune is with wide band tuning in order to adjust you engine ECU to the right Air Fuel mixture.

my two cents...

so which method cheaper? sick of petrol smell from muffler

- Brand new AFR cost is ard rm3++ (Arospeed), been using it, and it's worth it for investment. Pls buy the original, the campalang one is likely to leak either from the vacuum or from the adjustment bolt.

- Brand new piggyback price is rm8++ to rm2k++, 2nd hand piggyback from rm3++ to rm1k++ (old - almost new version)

AFR wat is recomend setting for standard 4g91?

Depends on your fuel pump pressure, there is no base setting for the same engine setup.

Install afr and pressure gauge
disconnect vacuum hose to afr
start engine and idle
turn adjuster knob to default psi (applies to stock injectors of course)
kill engine
reconnect vacuum hose
start engine. At idle the pressure should be less than the default value. On boost should be more

Do this tips when your engine's still hot.

you can tune your regulator slightly above stock, for a more responsive car, with the lost of a little higher fuel consumption, but it wont really help if u need more fuel to richer up an overly lean
mixture...

Got this info from the other forum for detail explanation

nieto udah ka masuk AFR..?hehehe

belum lagi, mahu masuk sekali dengan safc 2. AFR belum tentu mahu beli apa, beli sard takut kena tipu ciplak punya. mungkin beli ARospeed punya.

pakai saja Arospeed punya AFR, lebih worth it, walaupun murah tapi berkualiti....

arospeed punya afr harga dekat sama dengan sard bro.
