Lightened Flywheel Drivability

[Dr Phil]

Hey All

I'm planning on putting a lightened 1.0l flywheel into my car. The lightening and installation is straight forward and has been covered loads, but...

For anyone who has done it, how badly has it affected day to day drivability? So stalling, or dodgy gear changes and the like?

just a bit of stalling in 1st gear

Cheers frank.

I think I remember reading a post of yours were you got it down to 3.5kg?

 

[frank]

yes 4 ish
this one is just a torque converter backplate

I've been using a JUN ultralight 3.4kg flywheel with a really heavy duty 200mm Helix organic clutch on a daily basis since 2010 and imho you get used to it with practice, the same as adapting to any vehicle.

it only stalls if you don't give enough revs or don't pay attention but you soon learn the fine balance between clutch-slip vs throttle vs rpm. the rapid engine response is gr8 for accelerating, upshifts, downshifts with heel&toe. idles like normal too.

Cheers Polly, that's the reassurance I needed

Clutch will be standard for now so that should help with day-to-day drivability.
