Lightened Flywheel Opinions - CJ_Derv - 05-02-2013
Hi Guys,
Now just a quicky really to see who has done it, now i believe that lightening a flywheel 'Doesn't' Reduce torque after reading many sites on the internet, i had one on my blaze but just with a T2 and Gov modded Bosch, and it was a nippy little fucker TBH, JP came out in it when we had fine tuned the bosch pump.
Ive got a 4 paddle clutch Ash spotted on ebay which i got for a steal at £70 and took the flywheel off blaze engine this weekend ready for fitting.
Just wondering what people think regarding this topic

I've got a lightened fly on my '6 and highly recommend them. The pick-up is way more crisp, and the throttle response is marginally improved as a result of the reduced spinning inertia. It's a worthwhile mod, but it's a Lot of money from Lynx for the billet one as I did!!
RE: Lightened Flywheel Opinions - CJ_Derv - 05-02-2013
I noticed a major difference compared to the original, but its an original which has been machined lol can imagine the cost of a lynx one. Should be interesting if i can get it on the dyno to see any difference as not changing anything else till had it dyno'd again and can put up a comparison
RE: Lightened Flywheel Opinions - Ruan - 05-02-2013
It'll feel less "torquey" at low RPMs due to the fact there's less inertia, but it'll feel to pick up faster, the revs rise and fall quicker, it juts feels a "happier" engine...
But it does make it easier to stall and also the governor will feel sometimes like it has more of a mind of it's own as it's used to the almost dashpot effect that the heavy flywheel gives.

Well worth it imo...and mine was never a proper expensive billet one, just a stock one with a load of material removed ont he lathe... But made the engine alot more lively / talked to me much better with it.

What ruan said.
It will fell like a happier engine all round but they are easier to stall, harder to make feel smooth when driving slowly, technically reduce your motorway fuel economy and feel less torquey.
If you can cope with not being able to drive it on the clutch then youll like it.
RE: Lightened Flywheel Opinions - CJ_Derv - 05-02-2013
Sweet thanks for replies guys looking forwsrd to having it on and now with a bigger blower, did anyone notice any reduction in lag possibly with the faster engine pickup? Im treating her to a full service too
Yes Darren mines had a fair bit removed too cant remember how much may weight it and compare with the standard one taking off
Im currently looking into more internal mods for my 11mm pump ruan so should be fun with an 11mm and lightened fly and TD04

Well ive managed to get a sprung paddle clutch unused from a project for 70quid rather than an unsprung so shall see how we go
The blaze was just a few seconds quicker than my mates focus st170 dyno'd at 185 bhp and quarter mile was 0.5 seconds quicker so hopefully should be a major improvement on the blaze
RE: Lightened Flywheel Opinions - ozonehostile - 06-02-2013
I had a drive in a 205s xud with a lightened flywheel, it was very easy to get revving, but not my cup of tea tbh, I love lowdown torque too much
RE: Lightened Flywheel Opinions - Rippthrough - 06-02-2013
You generate more low down torque at the wheels with a lightweight flywheel, not less.
RE: Lightened Flywheel Opinions - CJ_Derv - 06-02-2013
Was waiting for someone to put that as ive read it whilst researching

Because less engine torque is 'lost' spinning up the weight of the fly....
RE: Lightened Flywheel Opinions - CJ_Derv - 07-02-2013
Well just dropped at garage got it up on ramps and cv boots gone along with engine mounts so shes gettin treated lol
Looking forward to taking her for a spin tonight when i get her back
RE: Lightened Flywheel Opinions - CJ_Derv - 11-02-2013
Well lightened flywheel has made a big difference, turbo seems to spool up a tad lower in revs only a tad but noticable and revs nice and freely, have to dab on the revs with the paddle as not to stall but is a good mod
