Agreed on the lightweight crank pulley part
Not to mention normal drivability suffer(A/C Not Cold,Engine easier to stall etc)

this not a issue if the aftermarket lcp is same size with stock not those undersize . i installed a handful since i work as mechanic for a living

now i get it .
either u are the chief mechanic at pagini factory or team renault f1 chief development and u never seen local paliah scene that most were homemade brew recipe . sorry to degrading you

Nope lol. Engineer for oil and gas electrical, work with motors and generators of the biggest sizes. Projects include the Condamine power station with Siemens SGT series turbines and Allen Bradley VSD control system.

I've built a lot of pariah industrial rigs where I work, but no play play one, all must calculate banyak banyak especially when it comes to moving stuff lah. Deswai I no likely LCP, given bad dampening of lighter material, the enjin will goncang goncang. That's no good.

sure u master MOM, DOM, KDM & struc mechs subjects..

and jumping off baskets... unless he goes to work by heli.

Dampening the crank pulley is definitely a good thing, especially to absorb vibration, but in essence like what empire said in most of his posts, a lightened crank pulley at most shaves off 2kgs tops on a singular part which doesnt really make a significant difference on a mild or road spec car. dont get me wrong, 2kgs on a track car makes a shit load of diff, but those engines are balanced, blueprinted and stripped down after the race. Your crank and engine internals are not expected to last 100 000km as a regular street car is usually overhauled.

Its attached via a belt, even your crank has torsion stresses.

this will definitely become unbalanced once the springs lose their tensile strength..how often does this need replacing? im guessing very..

Added on January 27, 2012, 3:35 amThere is a significant difference between a mechanic and an engine builder. Also an engineer. I remember a mechanic guy in LYN said he came up with a brilliant design to fit an intercooler to the intake of NA cars.. In fact he was selling the kit and installation service to other car owners.

The purpose? to cool ambient air to ambient temperature

I have some basics in mechanical but most of it is on the job training and customers shouting at me they want XXXX MTBF and they want numbarrrssss........you learn veli fast when your ass is on the line

On a real race car, sure the 2kg lost with a lightened fly wheel, plus Delrin Acetal tensioners, carbon fiber covers, sodium filled shaved valves, ultra light timing chains, crashbox straight cut SMGs and so on all make a difference. But remember, most of our cars aren't race cars and I wouldn't want the reliability of one. I still want to go out and buy susu, go Giant, ayam goreng McDs, go 7-11 at Ampang Jaya beli berger and so forth.

The central hub of a clutch is usually replaced with the clutch. Usually comes in a kit. But you are right, they take a kicking and sometimes under the right circumstances and enough stupidity, they will crack

that flywheel is rather interesting..where can I get more information on it? Also is there any particular name for it?

It's just a removable hub for a cluch. Normally they aren't removable or even splined for that matter, but the picture is from a Nismo SuperCoppermix which I wanted to order for the 34.

Most everyday clutches will have a unsplined hub with springs.


Now compare it with Exedy's top of the line carbon clutch for race use only.

Look ma, no springs

ur flywheel so high tech miaa... what drivetrain u using???....

ok.. so did u send ur engine for full balancing and blue print??.. i'm sure as an engineer u cannot tolerate any defects due to large manufacturing tolerance right??....

That's a Nissan SuperCoppermix for the R34 la.

Me drivetrain, DSG style TC-SST, with fully reworkable torque limit maps accessed via a CobbTuning AccessPort.

Large manufacturing tolerances? I think I paid so much money for the Evo X precisely for the reason that they've already reduced the tolerances at the factory for me . Although I do have a set of Cosworth pistons and Ferrea valves lying around somewhere in the store waiting for slight grinding.

But the reality is that you can accept failure in tolerance somewhere, but not others. A road car should prize reliability and drivability above all. One could remove the aircon from their car and get a quite a few extra horsies, but I rather just get a car with more grunt than lose the aircon.

bad tensioning?

Drex, since youre here, can you shed some light on who Mythelogy actually are? Ive tried looking up information on this company and I cant find any.

The question is :
Who are/is mythelogy?
When was the company founded and by who?
Whats their pedigree or experience in manufacturing car parts etc..

Since EA autoworks supplies their crankpullies, I guess youre the best person to ask..

then care to explain how my engine is still running fine after 200,000km with a lcp installed, plug and play?

simple..

1) you own a workshop
2)ive never heard a bad review of your services means you know your shit and you do a good job.in fact before you even quota a price you always ajak ppl over to discuss what needs to be done and have a look at ur workmanship.

do you dare vouch for the quality of products you dont carry or the services of any other workshop?

well...... i'm using mytheology lcp on my sic bi(th.....

I still dont get it ? ur answer looks more like shoe licking and butt polishing unker maddriver . i tot u earliar said lighten crank pulley will destroy crank .
and i believe maddriver sold many of these and install on totally standard engine without any1 race prep and harmonic balancing . care to explain ?
