in gettin a new enigne soon running at 213bhp roughly and weel then engine out i fort about getting the fly wheel lightend is it worth it
and how much does it cost
cheers phil

[martyc]

to be honest no its not worth it except for competition use or on cars with massively overweight ones as standard as for price couldn't help there sorry

It only works well if you do other mods to increase the rev range of the car.

I wouldn't have said either of the above are *strictly* true from my understanding of lightened flywheels, but then I have only really just touched on looking into them.

A site to have a read of is http://www.pumaracing.co.uk and more precisely, take a look at this page: http://www.pumaracing.co.uk/flywheel.htm

It's something I've been considering for a while, but not until my clutch goes

I'm not sure if it was on the above site that I read it, but I don't believe the benefits are as good for a turbo engine as an NA engine. I can't remember why now though, sorry!

Not worth doing unless you do the rest of the engine. On it's own the difference is so minimal the outlay just isn't worth it.

I would say what I said is true.

The whole point of lightening the fly wheel is to be able to increase the reving ability of a car which as you said is more important in an n/a car. As Oranoco said it's only worth doing if you uprate other components to such as high rev range cam/vtec , headwork, type of lifters, valves and general weight and strength of engine components is more[i/] important than a turbo engine.

However lightened and balanced engines tend to have higher/more erratic idles and work well only when being raged round the track, so pretty pointless in an everyday car. Having said that there are various levels of lightening, so mild lightening may be possible on your road car but not worth it... imo...

Another thing to consider is, a car with a lightend flywheel will LOOSE torque at lower revs.

Sorry, I wasn't trying to suggest what you said was wrong because I know it's not but I asterisked strictly because I would also say that it's not just a competition engine or an engine with other mods that would benefit - Different engines/cars will benefit differently from a lightened flywheel.

It's something I've been considering, but no intention of doing until I can find out more about how well it would work with a Zetec engine.

With regards to the idle, that again is something that some people claim is an issue, and others do not (on road cars), but like you say, it does depend on the level of lightening.

A lightened flywheel will benefit acceleration, more so in the lower gears.

The biggest problem with a light weight flywheel can be pulling away smoothly. The less weight your car has the less you will notice this eg stripped out track car. Remember ford made the flywheel heavy enough for a smooth pull away in a a five up car.

Lightening the stock cast iron flywheel can be dangerous. They can throw themselves apart with lethal consequences.

Best is to buy a lightweight steel item.

I have dealings with a company that CNC machines these for many of the big tuners/performance part suppliers. I could get a group organised with a major discount if people were interested?

i would prob be interested in a lightened fly wheel for my CVH lump,i was advise from other people that it is a little pointless unless resat of bottom end is lightened/balanced.chances are the bottom end end will get an over haul in the process .what sort of prices are we talking rowdy?

[frostie]

hi there i have a lightened flywheel on my 1.8 fiesta si soon to be a 2.0ltr in 1 week i have had no problems pulls away smoothly and fine no notice in loss of torque to be honest feels alot better especially when in like 4th gear just but your foot down just pulls away picks up faster i really noticed it straight away did on my old 1.3 hcs made huge improvement too ive taken 3kg of the flywheel which weight .... well carnt remeber but i was impressed how much we maanage to get off on the lathe i won recommend it if you can do it cheaply and you got facilties i wouldnt go out of my way to do it like take gearbox out to do no point just do it when i was fitting my 1800 or when fitting a clutch i just had the opportunity and it was free!!!!!!!

cheers frostie

Yea as said, Iv heard horror stories where the flywheel has shattered and sent shrapnel through the bellhousing, through the bulkhead and hit passengers

See what kind of deal you can sum up rowdy
