lol brother 50kg is quite alot adi ler...hehe almost 70-80% of a human guy weight jor...lolz & not to mention like my car which have abs adding an additional 50kg weight to it, even my stock seat is dem heavy...lolz but 8.4 sec...errr i not sure possible or not...how heavy is the neo adi ar? 1150?

the ones without the damper is probabily undersized. that's why u find the performance slightly better.............but the trade off is that becos the pulley is smaller, the air con won't be as cold and the alternator and power steering pump will not be working at optimum during idling.

hmm true true....wonder isit true i never really try b4...have to sit on others plp car & try then oni know lolz..hehe

Oh.. Changing the pulley size will effect so many engine parts?
Didnt know that

yup. the pulley size is calculated by the manufacturer to give the best performance to reliability ratio as possible...

changing anything if not done properly is going to effect some thing or another...

i tink the effect of lightened pulley is almost the same as lightened flywheel.. easy to accelerate but will come to stall fast oso bcz of reduced moment of inertia.
besides changing the pulley, i hav heard ppl adjust the angle of the pulley sprocket....by a small angle,mayb 5deg,so that spark will come earli and combustion happens earlier,which wil avoid power loss. From an automotive book that i read,spark naturally should be out before the piston reaches its TDC(top dead center) / when compression stroke occurs.

shinjite is another satisfied user of the pulley

Yeah~~seriously can feel a difference in acceleration

maddriver : Even you are surprised, isn't it?

the very first time i had that pulley was on my waja 3 years ago. at that time, to custom make one of those with a damper cost me rm900++. and, boy, was i suprised with the improvement!

shinjite, what car u r driving?
mind to share the experience?

Just a slow and normal 4G92 1.6 Wira auto
Experience will be faster revs loh, pickup is faster

If my car is a manual, even better pickup

can wheelspin or not? 1st gear la
kindly monitor if it helps on fc...
i plan to change car but hand itchy to keep my current car n mod it...

no need wheel spin, for what...useless
You wheelspin, I lift off already
On FC it depends on your driving style ler....mine still the same or even better

haha, if can wheel spin even for auto, means more torque transmitted to wheels ma

don't want ler, I let the car just go ler~~~
No time for wheel spin also

Because auto need time to full revs also mah....that time also delay liao

So after fixing this thing U get more Torque lar?
I tot of doing this to my Wira oso.. But then.. Its a carby car..dunno should anot.

Dont know how much it would cost.. I dont think it will be sub 500$ rite?

Dunno who does it around Penang...can I like buy the thing and then let my mechanic fix it?

the pulley costs rm600 excluding freight. can post it to penang if u're interested

what about the MYTHELOGY crank pulley problem of squeaking sound when the engine is cold, i do not think their explanation to the problem is believable.

MYTHELOGY

boss, your pulley lightened and dampened ar?

yeah lightened and dampened
