Yeah~~seriously can feel a difference in acceleration

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!

Experience will be faster revs loh, pickup is faster

If my car is a manual, even better pickup tongue.gif

You wheelspin, I lift off already tongue.gif
On FC it depends on your driving style ler....mine still the same or even better smile.gif

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

my waja now in Maddriver's garage for new pulley and 550 degree pads...now waiting anxiously.... kekkekeee laugh.gif

btw, just sat on maddriver's 4g92 satria...... nice to see the rev up to 7500rpm ....with stiff shocks, less comfortable but nice handling! rclxms.gif

hahaa, he said he is very satisfied with the car now....
wonder how much $$ he has put it...
1st, 2nd gear wheel spin
3rd gear got minimal wheel spin.... impressive enuff for 4g92 sohc la smile.gif

my car not ready yet, still at maddriver garage.... waiting anxiously... drool.gif

havent test drive yet.... will let u guys know tomorrow.... icon_idea.gif
550 degree pads were fitted in too!

i will upload pic as well on the golden brown crank pulley tomorrow wink.gif

yo guys.....

hmm, how shd i start this short review.... laugh.gif

For lightened pulley:
Attached Image
With a light tap on the accelerator, the car surges forward... most beneficial is the 1st gear. (of coz la) rclxms.gif
Throughout yesterday journey back home, i drove like usual and the car reach the usual crusing speed (90km/h) much faster. As for constant cruising, i find myself lifting off the accelerator much much often as a slight tapping on accelerator will bring the car back to the usual speed.

This morning at connaught highway, acceleration from 50km/h to 90km/h on 3rd gear on my Waja 1.6 Auto was much better... usually i will press the accelerator harder to downshift to 2nd and pull until 70km/h for overtaking... but now i just need to maintain 3rd gear and the car pull all the way to 90km/h without much hesitation from the engine.

When going up slope with 3rd gear at 45km/h, i will always need to use 2nd gear as on 3rd gear, the engine rev refuse to go up, instead the rev drops. With this pulley, the rev is climbing steadily, although not fast tongue.gif

As for fuel saving part with this pulley, it is too early to tell, but based on the driving style that u need to adapt, which is lighter throttle, and the ability for the car to go faster with highest gear, i believed it is possible. nod.gif

This pulley makes big difference especially at low rev
honestly, i cant feel any difference when revving at 5krpm above.... anyway, my waja 4g18 is not a high revving engine. tongue.gif somehow expected.
So IMHO, most beneficial part for lighted pulley is at stop and go traffic. It makes the driving more pleasurable. Although my car is coupled with a lagging gearbox, the car seemed to be very light. biggrin.gif

Overall, i am satisfied smile.gif For a heavy car like waja with auto transmission, it gives much better driving experience.
But not managed to test the car with 5 ppl onboard yet. Will update if i managed to test it.


550 degree pad:
I changed only the front pads while maintaining my old ones for rears. The pads were blue in color, as u guys can see in the pic. These pads has not thoroughly run in yet.... but yet it is already felt much better than my previous pads. As of now, the pads has only gone thru less than 80km. My previous pads was recommended by some mech and it was much better than proton ori's mintye. (mintye rite? i always confused between mintex and mintye). Thus if any of u guys using mintye, upgrading to these pads will give h3ll a lot of differences!
Attached Image
High speed braking was much improved compared to the pads i have earlier. A 30% pedal will bring the car stop confidently as compared to my previous pads, which i need to step 50%. (Note: waja braking feel is different compared to Jap cars like sentra or vios... ). Braking effort required when jam bumper to bumper is much lesser and relaxing now.

there is no cold bite problem with this pad. The pads provide braking force like usual in the morning.
Well, i will try the brakes on genting downhill if got chance smile.gif But need to run in the pads first... hehehe. laugh.gif At the same time, i can test the lightened pulley as well.

Overall, the pads are very satisfactory!

Avoid from double charging in the future plus, I had some serious problem with my brakes, my right side jammed.....freaking dangerous. End up overhauling both sides, new brake fluid DOT 4 and brake pads. On that day no stock for 550, so got 450 instead. When the time comes, I'll get the 550 ler XD

Good crank pulley review dude, mine also can feel the difference. 1st gear to 3rd gear can feel a lot of difference. 4th gear can reach 120km/h way faster than last time smile.gif
*
wow, sounds dangerous la. ur caliper jammed izzit? the new pads shd last u for another 1 1/2 to 2 years i guess.... hehe.
i changed front only... the back remain old pads...

i think the lightened pulley shd benefit more on manual.... somehow there are times where i see the rpm climbing but the car not moving faster....then suddenly got a slight surge.... i think shd be due to torque converter lags.... hmm.gif

one thing funny... my engine note is different now when revving.... it sounded more garang la...which i dun really understand.... rclxub.gif sweat.gif
how bout urs?? rolleyes.gif

i wonder how does maddriver's pads stacks up against mintex, EBC, Endless, yadda yadda....

currently on G.tech M3 and they suck even worse than perodua's stock pads.

if compare with mintye, mintye can tapau balik rumah tongue.gif
haha, i cant compare coz using some oem pads....

Mine ah....still the same, not much of a difference XD
My rear brake pads still using original pads, focus is still at the front smile.gif
If front tak makan, rear won't help already XD

Yup me 2 sometimes, its because the gear haven't change yet....my auto tranny definitely lags a bit, old technology tongue.gif Waja is way way better

Next time can meet up and discuss XD

hmm, then funny lor... maybe the sound is psychological effect gua.... sweat.gif
haha, yeah. maybe can meet up at maddie's garage and chat....and kacau him also tongue.gif but a bit far la....kekeke sweat.gif
i sit in my fren's putra auto..... it doesnt really lag that much ....although i see the way he drive quite torturing the GB...
i guess for proton car's tranny, putra auto one shd be the best gua.... unsure.gif

my FC will reveal after this tank smile.gif now clocking on 22xkm
next refill shd be somewhere next week
last tank still managed to get 10km/l after some short period crazy driving with new pulley tongue.gif

btw, to all the guys that read my lightened pulley review, my waja has some mod done prior to crank pulley installation....

my mod was zenden 4-2-1 extractor and de-cat.
for auto user i dun really recommend to de-cat as it doesnt do much effect.....imho.

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 rclxms.gif  never expected so much improvement flex.gif  that's almost 1km per litre more than i got withj the standard pulley rclxub.gif

icic.....
i saw the discussion in zth and it sounds like very impressive... tongue.gif


sounds great on the fc!! despite ur mad driving style...hehehe whistling.gif
my next refill shd be in these 2 days.... clocking 44xkm now.... icon_idea.gif
normally i refill when meter reach 500km or low fuel warning light came up (stupid fuel gauge rosak..).... if reach 550km then only warning light came up, i am happy! thumbup.gif

actually, decat does help.. less restriction, slightly higher top speed
my jazz last time decat, around 2.5k rpm, i'll be around 110km/h

now revert back to stock.. 2.5k rpm, 100km/h
pickup also slower and i have to rev more... throttle also feels heavier...

for crank pulley, its good for acceleration and low end power...
problem is when u have built speed, a lighter pulley has less momentum.....
*
on acceleration wise, the lightened crank pulley serves best when the engine is within it's torque band.....

my 4g18 torque band after changing extractor is somewhere between 2k to 3.8k... (butt dyno feeling la.... nvr go dyno b4, no point la laugh.gif), the surge from 3k onwards was most noticeable....
but after 4.3k.... yawn.gif shakehead.gif engine characteristic i would say.... hehhe

thus i think for vtec user, when vtec surges, the difference shd be much much greater when using lightened pulley.... smile.gif

our pulleys are half the weight of oem pulleys.

as for your question on power gains, u'll feel the engine being more free revving, thus faster pick-up and u'll also reach your top spped faster. however, if u do not drive like a madman every day, u'll also notive some savings in fuel compared to using an oem pulley.
*
lol..... after install the pulley, u can't resist to drive like normal man! drool.gif
u sure love revving the engine.... kekekekee. blush.gif
hmm, one thing i forgot to add last time while having my pulley around in the engine.... accelerating downhill is very much faster biggrin.gif

bro maddie, by leaving the car few hours to u instead of overnight, can settle the pulley creation?
