Lightweight Flywheel - Saxperience

Byard · 21st May 2010, 10:45

Anyone got one, how does it compare to standard?

Stevo123 · 21st May 2010, 11:10

From comments on here your engine will rev quicker (more response) and the car will accelerate faster. It may be harder to drive in traffic because it will be easier to stall and idle may be slightly worse. General conclusion though is that the positives out weigh the negetives though so go for it mate.

one more problem is that due to the lighter flywheel it will be harder to travel up hills because their is less momentum than a heavier wheel

Byard · 21st May 2010, 11:42

Less momentum but easier to drive it (the flywheel) so should still be the same I would have thought

looking at getting one atm as my car needs gearbox and clutch so thought might get one as i can get clutch kit and lightened flywheel for £100 hmmmm coupled with a VTS box should be good shittt

I changed my VTR box for a VTS one... wished id have never done it, changing gear all the time, revving its arse off at 80mph... cost about 30 quid to get to Whitby

Its better if your accelerating hard, or using the gears on a track/fast road

However if you are cruising down the motorway you will be in 5th gear at 70/80mph and the car will be revving at 4K+ rpm

But TBH i dont do much motorway driving and if i do its not for long so its all good in the hood

what benifit will the vts box give a vtr? thought it would be slower?

SaxoJamie · 22nd May 2010, 23:52

Should make a good difference the car will be much faster up the revs but going uphill you might notice it doess slow down quicker but just use a lower gear than you would anyway before a very steep hill.

VTS box has shorter gear ratios than the long VTR ones so it will rev up faster (quicker acceleration)

H-Unwin · 23rd May 2010, 01:18

as said above makes acceloration quicker but slows top end but tbh youve got some nuts in my opinion going for 140 in a sandwich box haha

BLACK-SAXO-V-T-R · 23rd May 2010, 02:13

had a lightened in an old car and when letting off the throttle cant be a little jumpy

due to the lighter spining mass of the flywheel

was worth doing tho

blackie_2k5 · 23rd May 2010, 02:59

lightend fly wheel is a good mod in a well tuned car, not much gain from a near stock car, yes it will rev more freely, yes it will screw you on a gradient, but not much bang for your buck tbh(unless in a well tuned car mainly n/a..as a proper one is damn expensive) wouldnt even think about having you stock flywheel lightened unless you have someone reputable on hand who knows what and how to lighten it... and more to the point BALANCE it, or youll end up wth more probs then youd ever want.. my 2p

No
The flywheel is the same as removing weight from the car. It will not affect going up hills. Grand Tourismo is wrong...

rushy_23 · 23rd May 2010, 10:04

^^^

I was just going to say that. Grand Turismo has a lot to answer for!

My L&B standard flywheel made no real noticable difference to the car other than it being REALLY jerky when rolling in first gear. Is "funny" at times when you dont expect it.. for other drivers staring at you.

sexy_gt · 23rd May 2010, 14:36

how many of you who have commented actualy have one??? lol

i do

i have the billet 3.1kilo from atspeed £235delivered before you ask

i fit one to my fast road car (used once a month for trackdays) to compliment a new valeo clutch (£95) as my standard flywheel was worn.

they are not hard to drive about in traffic etc.

they do not slow you down when going up hills.

they do give better throttle responce.

no extra power to be gained.

they do make your car idle worse if it isnt perfect to begin with.

you do not need to balance the standard fly when balanced lightend.

and lastly if you do have your standard flywheel lightened then 1kilo will be the max to safely remove. hardly worth doing.

back to the original question. not much difference at all.

KamRacing · 23rd May 2010, 16:11

even a kilo off a standard one makes a noticeable difference to throttle response/ acceleration, but i'd only fit one if I had the gearbox off already.

cenas · 24th May 2010, 16:31

I've a little bit less weight in flywheel and the car it's quicker and i did not lost Top Speed!

unless you are using a lug drive alloy type racing clutch ,then the weight of your clutch cover + plate will be as much as the flywheel --so lightening it makes very little dif on anything other than a full race engine --
weigh them ,then see where on the dia you can remove the weight --mostly in the middle, so removing weight in the middle has far less effect than removing weight at the outside of any rotating object ..
do the maths -- 1lb weight at a radius of 1ft =1lbft .to get same reuction at 6" you must take off twice the weight .
no doubt you will be using big wheels +tyres --they also act like flywheels ,so you can take far more wight off them by using light weight rims ,also makes suspension work better --less"unsprung weight".
you can save 20kgs by buying mag rims ,whole flywheel only weighs about 5.5kgs
