You can usually find used lightweight flywheels for around 100, I think lighter the better, a heavier flywheel is smoother with a harder clutch.
^^ this.. are you going to drag race this or road race/autox it?I like my Fidanza. I'd stick to a 12lb'er if you're gonna drag it, I went for the lightest I could on my autox setup.
Truth Be ToldI'm not sure what all this "falling out of boost" business is.
Don't tell me you're letting out of the throttle to shift...
lmao!!!!!! ahahaha this officially made my dayJust get a tungsten crankshaft:
Lol in all seriousness though, if you have a small turbo that doesn't take much to spool (plus you higher than average compression for a turbo build) then you may not need to worry too much about falling out of boost too much. I still vote for a stock flywheel for the cost to worth ration.
I'm running a 7 lb'er, I don't get any noise from the engine. what about acceleration though in stop and go traffic? I deffinately feel like it has more pick up go, its really throttle responsive. momentum with the 7lb'er sucks for climbing hills though, didtn really notice any difference on flat roads at cruising speedsI going back to stock because I do fall out of boost between shift some of it has to deal with my tranmission the separation beween gears and the big turbo that I am running. I'm also going to a comp clutch sprong six puck with dual pressure plate because my current act is getting wore out but been a very good clutch.
I currently have a 7lb but I don't belive you should run one this light because the fly wheel kinda acts like a dampner for the engine I would stick with something arournd the 12lb range. I know of this because I have a lot of harmonics noise that travels through my car because of the engine.
I think heavier flywheels to a point help with fuel mileage also because it keeps the momentum up at crusing speeds so the engine dosent have to work so hard to keep turning to maintain that speed.
