4G15 powderfull what

Want gain both response and top speed , must upgrade engine den

theory its like the HI Cam system , want Hi End , sacrifice low end . Want low end , sacrifice high end

same like exhaust system as well.

before this try change at 4g63 sohc engine (perdana sei) manual.. top speed kinda same, but engine respond a bit lighter..

this is to lighten the engine, good to reduce powerloss being transferred..should not lower the topspeed...top speed related to engine power, gearbox and drag

how is mythelogy LCP ah?

Will light crank pulley lost top speed in 4g15 engine?

i would like to say nothing lost in speed for g15

Have been a happy user of myth lcp for years....first time installed,tak rasa apa apa.....
Then drive with five people in car,can feel liao. Same feeling u driving alone.
Even my wife who drive knows......its ilighter,but dont la expect tebabo power.

It won't lower your top speed, but remember as you go up in the revs and power, the lighter crank pulleys might not stand up to punishing use and if they do give way, well, your engine is screwed.

not that I'm against LCP but it does screw up the engine. search around and you will understand why.

LOL! You tell me?

I got mine from drex afew years ago. It got the ruber thingy to absorb vibration....
Just check recently,the rubber still sitting nicely. Marked with chalked,tested 190kmph, the chalk marking still same. Means no slip between rubber and pulley. U get wat u pay for.mno regrets.

ah icic. thanks so much for ur feedback.

My myth since 2006 till now, running strong

What is myth? Any 4g15 users here with LCP?

Depends on what engine ... Not all engine use LCP well boom ur whole engine ... known many friends that use LCP dam many years and still strong running healthy dont just read reviews n judge LCP are not good . Dont judge a book by its cover yea ?

Mytheology lcp.
Lazy type in full...hard to spell...

Same. I also have source and owners having their engine jeopardized by LCP. As you've mentioned, it depends on engine. Well, i disagree. I would say it depends solely on the aftermarket LCP. An incorrect LCP size, weight and dampers may invite trouble. Again, I would like to stress, I have no grudge against LCP. I'm just creating awareness among users to be skeptic and becareful with aftermarket LCP. There are so many brands out there with some we've never heard b4. Some dodgy accessory shop will tell you, the lighter the better. If you're not sure, go with the reputable brands. saving a few hundred bucks can actually reduce the burden/stress on the engine.

Some reading materials.
