Can you get them for a euro?if so do you know how much and are they easy to fit?:cool:Quote:

How much? close to $400. Easy fit? from 0-10 I'd say 8. Getting a mechanic to do it costs $140. Gains are about 5 hp accross the band and excellent low rpm torque gain
the silver mugen one.Quote:

How long have you had them (the pulleys) on?I've heard there can be issues re:engine vibration which could affect engine longivity!!Quote:

You can do a search on that site for the original threads - just search for "harmonic" and you will find it.
I have them for almost 3 months now. Everything seems fine except as I mentioned earlier about the upgraded stereo caused problem as it killed my battery less than 1 month after installed. About the harmonic balance, I'm not really understand the principle of it but when I went to one workshop, he showed me crankshaft and its area. Pulley and flywheel it sort of connected by crankshaft so I would think changing fylwheels already creates unbalanced in the first place if we are talking about balanceQuote:

The posts above re the pulleys have been moved to this new thread:

Thanks
ps i have done this because people browsing the forum in the future can see the thread about pulleys easily - rather than the topic being 'hidden' within a hi-flo cat thread.
lol ok lets get back to topic then..
my best quote from the seller on acurazine was $360us which is $477 including shipping. But it will take 4-6 weeks to arrive. Well what do you guys think? Bolt on (RT cat) vs. Weld needed (metal)... Assuming for a bolt on cat I can DIY but for Metal cat I will need to go to shop.. so say $477 vs $440 ? I think interms of power gain, it wouldnt be much different I would guess.
