Hi,
1.Is the FLUID DAMPENED PULLEYS AVAILABLE yet?
2.why does it needs to be dampened? ( i ve been using non dampened for 5 yrs now)
3 What is the price differences between FLUID DAMPENED PULLEYS and the ones your selling now?
4.Do you hav st171 corona model?
5.How much do you charge by fabricating one for me?(st171)
6.Do you make other parts also? I.E. Water pulley, tension pulley or timing belt pulley set etc
7.Can I have your price for Vios, Myvi, Pajero, Corona (st171)?

Pls Email me your quote, Thanks
I can do the installation myself.


Added on March 9, 2008, 1:33 amMy email is r.kiong@hotmail.com. also can I hav your phone number too. thanks

1. dunno....
2. because minor vibration can cause serious engine damage to the crankshaft and engine bearing...
3. dunno....
4. dunno....
5. dunno....
6. dunno....
7. cannot... coz i dunno....

lol wut? installing crank pulley will make the rev go fast, and drop fast as well?

yes... but much less compare to lightened flywheel.... icon_rolleyes.gif

will lighter crank pulleys improve FC?
so if i want to upgrade it, make sure the diameter is the same as the stock pulleys?
*
yes.... LCP can improve ur fc a little....
diameter can be the same or undersize a little.... make sure not too much or u'll have trouble generating enough voltage from ur alternator or trouble running ur aircond compressor...

Understand that if install in vios ... the belt is easy fall out from the pulley...

what is the main cause?

Good Day,
    My long previous car of Proton Iswara Sedan 1.3 S , year 1996. Bought 2nd hand in year 2002.  I modified the cam pully and crankshaft  to an adjustable type. Spent Rm 2 K ++ for all the modification. Firstly, i fully overhaul the engine and replace all the gasket and oil seal to accomodate higher pressure and output. The result is impresive power output and lower fuel consumption. The Power output that time i can even win race between Peugeot 306 from Johor to K.L. maximum top speed i ever tried is 180 km/h ++ coz that's the limit my speedometer is.

    Exhaust system changed to 4 to 1 extractor . Distributor i put additional cooper internally the unit to boost power output but the plug cable remain the same. Absorber Kayaba original only + sport spring. Tyres 15" with Proton Waja rim. Front brake modified to accomodate Proton Perdana V6 brake system . Rear  maintain original.
  Drive about less than 4 months, i sold of the car. Reason, bored already due to high maintenance for an old car. All the rubber seal, power window, and air cond all spoilt. Worst, my rear bonnet use to fill up with water due to leakage and poor design of the car.

  Currently, owned 2 cars. Proton Waja Campro 1.6E, year 2007 and Nissan Sentra N16 1.8 XG-L , year 2007. All genuine original. More than sufficient.

correct me if I'm wrong. even if we lightened the crank pully and something else even by a massive 20kg of weight reduction, isn't that the car weight itself (more than 1000kg) will give the momentum/inertia (what ever u call it) to make the car keep on moving if we take our feet off the accelerator?
*
wrong... when u use LCP, u lightened the angular momentum of ur rotating crankshaft... not lightening the kerb weight of ur car... whenever we revs up, the engine requires more power to spin the rotating crank due to heavier momentum... by lightening it, this reduces parasitic drag of it...

i assume what he said is that even with LCP the rev will not going down faster than without LCP when the car move in gear

because the weight difference is too minor to feel any significant difference... try lightening ur flywheel 1kg or more... surely u can feel the difference...
