there are currently two types of lightened crank pulley in the market, one of which is undersized, and the other which comes with a damper. most of our standard pulleys comes with a rubber damper to absorb the critical vibrations comming from the crank.

advantage of having an undersized pulley is that the revs climb much faster. this is what we use in our race cars. with most race cars, we rebuild out engines much after every race, so con rod bearing wear is not a problem as we change the bearings during each rebuild. so con rod bearing wear is not a factor.

advantage of having a lightened and dampened pulley is that the revs will climb slightly faster, not as fast as the undersized pulleys, but with the damper in place, we will have peace of mind when it comes to the wear & tear of the con rod bearings.

hope this answers your questions on the crankshaft pulley

so far, the only jerk that i encounter during a traffic jam situation is that motobike that goes in and out of traffic

what car is your friend driving?

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.

shinjite is another satisfied user of the pulley

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!

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

that's becos the belt was not tensioned enuf. so far, i have not had and complaints from those who have fitted the pulley with me

it's everything that i expected

those shocks on my car was not made for comfort. but the handling's great!

glad u guys are enjoying the products, but the best products in the world cannot help u if u're not careful. drive safely and enjoy!

it takes about half an hour to change the pulley if we do not encounter any problems along the way, such as a stuborn crankshaft pulley bolt

bang for buck, my pads will stand up to any of the competition. EJ? subaru ej?

sure lah! i use all my products to the end of it's service life b4 i dare to sell them otherwise, how to tell if it's good or not? also, i don't like to use customer's cars as test subjects, unless they put a gun to my head and make me do it

just fixed my speedo cable today now can check if the claims made by some customers that this pulley saves petrol is true

i might be able to get a sample, and it'll take 1 week to custom make one for u. currently, i don't have any for your engine

figures just in. before the crank pulley, my consumption was about 11.8 km per litre, now it's 12.3km per litre at my usual driving style.

what do u normally get?

looks like u're almost talking about an engine rebuild

best not to do that becos those counter weights are there for a reason. even if we were to lighten a road going car's engine, we won't go to that extreme.

btw, results of my fuel consumption just in. 12.8 km per litre never expected so much improvement that's almost 1km per litre more than i got withj the standard pulley
