mari kita bincangkan...

bro utk enjin proton 1.3 adakah adjustable cam pulley..?...dmana jual bro..?..hee

ada bro, kalau tak silap dekat kk ada jual di titanium motorsport. kalau tak pun main order dari kl.

dmana 2 bro titanium motorsport..?..hehhe

penampang, bundusan. tapi kena masuk dalam dalam.

oh.....tq ah bro..hehehe

dekat kedai accesory 2020 yang baru punya. belakang saja, cari perlahan2 sampai dapat hehe

Pakai racing cam... cari atas 3++ degree, pakai Toda Racing atau OS Giken... bunyi ekzos pun power, brupp... brupp... brupp.... brupp.....

klu ACP masuk injin wira 1.5(4G15p) standat? bole ka?...adakah adjustnya sama macam page di atas?...

...just tanya sbb macam best...jwpn ringkas jak diperlukan...tq...

boleh xda masalah...

thanx bro...mau di cuba suda ni...budget dah ada cuma xtau jak nak up performance kereta...

cam arospeed tu maksimum berapa degree?

tidak pasti pula, utk street race, 272 degree kira ok suda, enjin punya bunyi masi macam ori, ada skit letup2, kalau lebih 272... idling mau kasi tinggi suda... psl timing lari kalau set pergi 800 rpm, enjin mati.. mungkin dlm 1.2k - 2k rpm gitu baru idling dia cantik

betul tu bro, aku sendiri mengalaminya skrg..idling smpai 1500rpm pun klu on ekon pandai mati2 itu injin.....mcamana mau atasi masalah ni ar?

Try service throttle body dulu bro, kebiasaannya lepas servis ok suda...
senang saja... kasi bersih saja bahagian dlm tempat adjust skru itu...

itu throttle body jenis yg bleh adjust kan...cmn pula klu jenis yg throtle elektronik...???

CAM DEGREEING







Is that a degree course in Cambridge? You can't be blamed if
that is your first thought, but no, it's not about an
education program in the UK.

Certainly, most of us have heard the saying, “Timing is
everything”? This is as true when making money in the stock
market as when it comes to making power in your engine. It
doesn’t matter if your stable of horses under your hood is
showroom-stock or after market-modified, but precise cam
timing is the key to maximize your engine performance. A bad
cam timing will inarguably rob you of your precious ponies
no matter what other power-adding gadgets you have put in
place.






Could the cam timing become out of sync, even in a new car?
Unfortunately, the answer is a plain yes. This can happen
because the engine parts are manufactured with certain
tolerances and there is bound to be some run-out in the
assembled engine. Although this kind of variance is
acceptable under engineering specifications, it means that
the engine performance will also vary from one to another.
So, you may get a top performer or you may get a slightly
less than average performer. However, most of the reasons
for inaccurate cam timing are repairs and modifications done
on the engine, for examples, after a cylinder head overhaul
job where the head deck has been skimmed, fitting in an
after-market high performance camshaft, or using a different
thickness head gasket.

How then can we ensure that the engine will perform to its
top form? The replacement of the original cam pulley with an
adjustable one is the simplest way to regain performance.
For fine-tuning the stock camshaft or tuning for performance
modifications, an adjustable cam pulley is the only way to
enable the required adjustment to be made. Apart from
setting the cam timing to the original factory specs to get
optimum engine performance, we can also increase low-end
torque for better throttle response by advancing the cam
timing a few degrees forward. Or we can shift the torque
curve upward for better top-end power by retarding the cam
timing a few degrees back.




With the adjustable cam pulley, we can accurately degree or
dial-in the required cam timing easily, with the right
know-how, of course. Having said that, always engage the
service of professional tuners to set the cam timing with
proper equipment. Doing it “by hand” is nothing more than a
guess work and a wrong setting can ruin the engine. Even a
small movement as “seen by the eye” on the cam pulley can
change the timing by as much as five or six degrees. Too
much advance or retard and the piston will hit the valves.
Be forewarned!

Among the trusted and well-known tuners in town is NS
Performance Tuning Sdn Bhd. Their PowerZone branded
adjustable cam pulleys use steel hubs to withstand the
fluctuating torsional stress that cam pulleys are subjected
to. If you prefer aluminum pulleys, make sure they are
machined from 6061T-6 aluminum or better. The common
aluminum found in many locally made after-market pulleys is
too soft and may fail, risking the life of your engine. So,
when in doubt, pick a steel hub pulley.

just a tips untuk kawan2...

perlu dail-in untuk proses tuning campulley..

-hepi mod-

dail gauge tu kalu tuner tak pandai..silap jadinya karang

yup...

kite ambik tuning 1 cam puli (sohc)RM150.00 (2jam siap)
dohc RM300.00 (4jam)...

bgs jga ACP ni tompinai...aerospeed pna jenama ACP ok ka tu..

OK ba tompinai, tapi kena beli ACP yg sesuai untuk enjin bro tuh, bukan pakai ACP utk enjin 4AG masuk ke 4G13P, hehehe
