Most tend to aid acceleration, will loose engine braking through the gears so more wear and tear on the brakes, unless you already have one or have a highly tunned engine i wouldnt bother tbh

Can't say I've noticed less engine braking all its done is improve acceleration loads well worth it. Only slightly annoying thing is the chatter on idle but mines not a daily
Standard clutch with lightened flywheel & it is easy to stall so god knows what it's like with an updated clutch!

Engine braking is provided by the vacuum etc in the engine in theory a heavy flywheel could reduce it a it'd wanna keep spinning?

Makes driving every day more of a chore. I think it also reduces throttle response. But it helps the engine to rev high, so if your looking for power figures it will help. It's one of those things you'd only do if you had the engine apart already.

should be the opposite with throttle response

Surely with less weight, it'll spin quicker/ rev so...

Reduced engine braking???? Its the exact opposite.

Reduces throttle response? Tell me what the point of one is if it does that

they are great, any engine builder will recomend fitting one. simple job to do and gains all round! best to buy a billet light weight flywheel cost around £200 for most vauxhalls. if your planing on or have increased bhp then i would recomend an uprated clutch at the same time.

Corsasport and mindless guesses at technical answers, well I never. I've got one on my XE and its bloody brilliant, wouldn't hesitate to recommend it

I wasn't very clear in my post, what I mean is that on intial acceleration (when pulling away) the car appears to be more sluggish. But once travelling it will rev easier. But racing off the line for example can be slower initially because of the reduced mass (stored energy)

Flywheels store intertial energy, lightening that isnt better in every situation. For instance going up hills car will slow down quicker and require more engine power to keep it moving, also at high speed car will lose speed quicker.

Also worse on fuel economy if you are worried about that sort of thing

reduced rotational mass on the crank, makes a world of difference to acceleration and response.

Yes and no, when you take your foot off the gas the car will slow down quicker too, so you could argue that is negative against performance

surely taking your foot of the throttle means you want to slow down anyway?

I think it is definitely very situation specific.

All im saying is it isnt all Pros to fitting lightened flywheels
