I don't think you understand Sid's argument. The point was "these companies don't have proper R&D" and the brands he quoted are all big names whom are well known to have their own R&D done on products they sell.

Anyway, regarding the discussion on the LCP and harmonic dampening - this is subjective. Race engines are stressed very much more than standard engines like yours and mine and hence their tolerance is very very small, which is why harmonic vibrations will affect a race engine. Stock Evo engines come with engine balancers to counter those harmonic vibrations that the engineers couldn't offset (probably at a reasonable costing) but aftermarket balancer delete kits are everywhere. Have yet to hear about any engines blowing up because of the balancer delete kit. Friend of mine had his Airtrek Turbo rebuilt, balanced and blueprinted. Removed the balancer and that was nearly 6 years ago, his Airtrek is still running fine. Basically I think it's about tolerance and how much is acceptable depending on what the application is. A stock engine or even a modded engine will not reach that level of sensitivity.

You deal with large manufacturing machines and I don't blame you for wanting to follow the same concept as those machines. For you any failure from these machines = money loss which is never acceptable in any organisation. So every meticulous detail you will consider - including harmonic dampening. Our street cars don't need this luxury and I honestly doubt a loose bolt will fly out and kill anyone anytime soon just because of supposed 'lack-of-R&D'. Malaysia is similar to China, if there is a product that's doing well, it'll be copied and rebranded. Does it mean there's no R&D? Not necessarily. The original product might have already done it and the copies are just leeching off the original idea since patents in M'sia are pretty much pointless.

I've been using a Myth pulley for close to 5 years now on my car. I don't own a workshop, I don't own a car parts shop, I am not a mechanic, I am not an engineer, I am only just an enthusiast. Whats more mine is a modified pulley which allows me to advance my ignition timing without touching the crank sensor (I'm using a VDO setup).

Sure. For VDO you can't manipulate the ignition timing. The only way is to modify the crank sensor holder assembly as what Drex has done or to advance it at the pulley. Mine had be drilled in to allow for a few degrees advancing. One of these days I'll take a picture but I'm worried some folks will try to copy me and then DIY it, then when something explodes he'll turn around and scold me for damaging his engine. (I was being sarcastic).

Anyway, if you're interested we can always talk in PM.
