what are the pros and cons from having a lightened clutch set up?

[Big_Adam]

Do you mean a whole lighten flywheel + backplate jobbie?

The engine will pick up quicker as it won't have to huff a lump of a flywheel round. Also helps idle on long duration cams.

Cons; .... ..... too light makes the engine stuggle to keep ticking over (I mean ultra light on a road car). Possibility of exploding.

lightened backplate, flywheel and orange diafragm.

Ah, thats what I'm going for. Steel one.

Should give a nice "peppy" pickup on throttle.

Yeah don't go for a rediciously light flywheel as going up steep hills is a b#tch

i have the MED stage 1 clutch set up now and am experiencing judder when down gearing. just wondered if its normal? sometimes when pulling away it does it too. by the way it does pick up like hell and revs alot higher. its also so smooth at higher speeds.

Errrmm.....wouldn't be going over 6000rpm if all you've done is a light flywheel.

dont understand what u mean mate, sorry lol

[samwell]

he reckons to safely go over 6000rpm youd need to have balanced crank etc because just the flywheels wouldnt do it?

More along the lines of valve bounce and piston rings destroying themselves.

And gudgeon pins. The flywheel is not what limits the engine rev band. The red line is set by the parts the reciprocate more than by those that rotate.

[blacktulip]

points taken, i mean it revs like it has a 3.4 diff even though i have a 3.1. so does everyone think i have a problem as it judders on downshifting?

[Big_Adam]

Well it's all new parts. My steel fly has a little oil on it from shipping. So it might need to bed in a bit. then again this is only speculation on my part.

Judder's more likely to be down to having a grippier diaphram.

I lighter flywheel will be kinder to your crank. the factory setup only weighs what it does to make for a smooth idle on the short duration cam.
