vr6power 1 Posted September 23, 2008 Report Share Posted September 23, 2008 i am doing a vr supercharged and just wondering would it be worth fitting a lightend flywheel or just keen the standerd cheers Link to post Share on other sites
cabrioman 6 Posted September 23, 2008 Report Share Posted September 23, 2008 most people are using standard one i think ... i got a lightend one but dont really notice it .. revs up a bit faster but thats about it Link to post Share on other sites

jims13 6 Posted September 25, 2008 Report Share Posted September 25, 2008 i dunno tony, we took 4lbs of jims one, and its very noticeable..we did machine as much off as poss though Link to post Share on other sites
jesterwalker69 0 Posted September 25, 2008 Report Share Posted September 25, 2008 I was just looking at getting a lightened flywheel so this topic is most helpfull.Whats better - buying a lightened and balanced on or doing as you've said Jim and machining your own down?

rigs 0 Posted September 26, 2008 Report Share Posted September 26, 2008 Personally I love the lightened flywheel in mine... Huge difference... Transforms an engine that feels a bit lazy in to one with a more sporty/edgy feel. Link to post Share on other sites
FishWick 21 Posted September 26, 2008 Report Share Posted September 26, 2008 Interesting..... think I'll try one when I install my gearset.I take it the main differences are pulling away in 1st and 2nd and a faster drop in engine speed between gear changes? Link to post Share on other sites
Matt W 4 Posted September 26, 2008 Report Share Posted September 26, 2008 I put one on mine when i did my chains and clutch and didn't notice that much difference. Car still idles the same and doesn't really rev and faster and the revs don't drop faster.I think cost effective is to get your current one machine and then balanced.

FishWick 21 Posted September 26, 2008 Report Share Posted September 26, 2008 It must depend on how light the flywheel is then. I was thinking of the one Bill Schimmel uses, he really rates it - http://www.spturboparts.com/aftermarket/ViewDetails.aspx?prod=16024Cromoly aswell.....so should last well with the uprated clutches we're starting to use these days.

Matt W 4 Posted September 26, 2008 Report Share Posted September 26, 2008 Hmm that would be nice as it comes with the starter ring gear, would go well with the 263 cams Link to post Share on other sites
Buddahwolfie 0 Posted September 30, 2008 Report Share Posted September 30, 2008 I got a Fidanza one in mine wich weighs 6lbs, it does make a difference and the revs drop much quicker but going uphills its not as good, its really make a good diff on flat, even roads.

gavinvr6 0 Posted September 30, 2008 Report Share Posted September 30, 2008 would it be worth fitting a lightened and balanced flywheel on a n/a engine, i cant afford forced induction but want to make the engine a little more lively. would it be worth fitting one in conjunction with a lightened and balanced crank and some cams?

rigs 0 Posted October 2, 2008 Report Share Posted October 2, 2008 Definately. Making the engine feel more lively is the main difference they make. Fast gear changes are smoother as there's less turning mass in the engine and revs equalise faster. Also, when braking and changing down rev equalisation on the clutch is faster and smoother or if you're a heal & tow fan it only takes a little blip of the throttle to send the revs racing.One of the best mods we did to our vr6 track toy...

gavinvr6 0 Posted October 2, 2008 Report Share Posted October 2, 2008 hmmmm i got a spare pair laying around somewhere, how light can i take the flywheel before it becomes to light, i've read of flywheels with 7lb taken from them or half the weight of stock. is it a case of the lighter the better or is to light dangerous? sorry for silly questions but if im gunna go this way i wanna get it right first time coz i cant afford to get another engine, im already on my second, lol.

rigs 0 Posted October 2, 2008 Report Share Posted October 2, 2008 Assuming the flywheel has enough meat left on it not to break its down to preference.Main benefit of heavier flywheel is clutch work on the road... standing starts are lazier and easier with more weight.

FishWick 21 Posted October 3, 2008 Report Share Posted October 3, 2008 If you're into full bore 1/4 mile launches, the spinning mass of the stock wheel helps get the car off line smoother.....less tendency to bog down.I would say the 6lb Fidanza is a tad too light imo, but I've ordered a 9lb cromoly steel flywheel and I'll report my findings.

FishWick 21 Posted October 6, 2008 Report Share Posted October 6, 2008 Yeah but your car does such little mileage though! I need feedback from people that run light flywheels on a daily basis in all the usual traffic scenarios :-) Link to post Share on other sites

I actually found the lightened wheel much easier on the quarter mile. It was more immediately adjustable off the line... also, the lesser weight made the change between 1st-2nd much faster as on the stock flywheel if you changed too quickly it'd break traction...A matter of taste maybe?

FishWick 21 Posted October 9, 2008 Report Share Posted October 9, 2008 I don't dispute that and I'm looking forward to trying my new flywheel - when I can be bothered to fit it!The kind of launches I'm referring to are in track cars with very tall 1st gears, such as the black Ventor Bill Schimmel built. He told me he gets much better launches with the stock flywheel, but prefers the light one for road use. Link to post Share on other sites
rigs 0 Posted October 9, 2008 Report Share Posted October 9, 2008 I'd say 800hp, drag slicks and custom gearboxes are fairly removed from the sort of cars they are asking about We were on a 3.9 FD, no diff and road tyres so traction was our biggest problem. Link to post Share on other sites
FishWick 21 Posted October 9, 2008 Report Share Posted October 9, 2008 I'll bet! Traction is bad enough with a 3.68 diff!do you get any more vibration from a light flywheel? I can't imagine you would but some folk reckon the flywheel's mass is partly to absorb conrod harmonics? Link to post Share on other sites
Cuske 0 Posted October 9, 2008 Report Share Posted October 9, 2008 I was just about to ask a question on this subject when I saw this thread, after reading I'm none the wiser. I'm just stuck between which to buy, a R1 at 10.6lbs or a fidanza at 6lbs. I'll read on as it's written I guess. Link to post Share on other sites

Got solid engine mounts too so it bounces and bumps rather alot anyway Link to post Share on other sites
