How light is too light? The factory flywheel is 26.5lb The toda racing flywheel is 12.7lb but somone is offering a JUN flywheel at a good price. 8.8lb. That's pretty fucking light. Less than a third of the factory weight. Significantly lighter than the "racing" one from toda. Maybe it's too spicy for the street idk.
fucking ricer, wrenchlet
>>27591079The lighter the better imo. They only make them heavy as fuck for ricers who can't drive since they love stalling out. T. Fidanza
>>27591089That's what I thought. I've got a light flywheel on my other v8 car but I've never seen one so much lighter than factory before. 8.8lb is nuts. The car is under 2000lb with triple the factory power so it might be ok
>>27591102>The car is under 2000lb with triple the factory power so it might be okInteresting. Well yea, the lighter it is the faster you can shift.
>>27591111I'm mainly just trying to get as much weight as possible out of the front end after swapping in a heavier engine. Smaller alternator, replacing all the cast iron brackets and mounts with aluminum etc. saving 18 pounds on a flywheel sounds pretty good.
>>2759107911lbs is the lowest I'd go on a street car. Source: have an frs with an 11lbs flywheel and it's borderline tolerable.
does anyone here have experience driving a 8-10lb flywheel daily? rebuilding my second cars motor right now and not sure what flywheel to get, as its mostly a weekend car but will be used when my main car is broken
lighter flywheel also means the idle gets more unstable at lower (factory) rpms, so you'll have to bring it up a bit to smooth it out. probably not a huge niggle for you considering that apparently your car and engine are heavily modified anyway.
>>27591133FRS is much heavier and a little weaker than my car so 8.8 might be tolerable.
>>27591079The McLaren F1 doesn't even have a flywheel. 0lbs is your answer lol
>>27591133did you notice much improvement going from stock to the 11lb flywheel? Source: got an frs for peanuts from a retard
Once swapped a flywheel from 1.6 diesel to a 2.5l audi a6 and acceleration was better but moving from standstill was rather annoying at times so i wouldnt do it for a daily driver.
>>27591174it's a fucking diesel why would you even bother
>>27591229Experimenting mostly. Old one got fucked and i had 1.6 one laying around.
>>27591174did you measure the weight diference between the 2?
>>27591079You talking BEAMS bra?The factory BEAMS flywheel is heavy as fuck because it's dual mass, so you can get away with a fair bit less weight.For reference my stock SW20 3S-GE flywheel is a little of 7 white man measurements in weight, so your JUN flywheel which comes it at over 4 white man weight measurements would be a bit heavier than half the weight - that doesn't seem unreasonable to me.
>>27591163mclaren f1 does have a flywheel gordon murray is a lying jewhttps://www.pistonheads.com/gassing/topic.asp?h=0&f=63&t=1460900&i=40
>>27591163>doesn't even have a flywheelwrenchlet, npc, underage
>>27591079At some point you have to raise the idle.The car will be a total shit to launch, needing more revving, wearing more clutch.There are much better ways to save weight, save light flywheel for a dedicated race build only.
>>27592547>he thinks people run lighter flywheels to save weight for the whole car
Do light weight flywheels jerk more at low rpms? Like foot off the gas, 2nd gear idle rpm coasting? Or is it more the clutch springs that dampen those shocks?
>>27592292Yeah bra>>27592692That is -part- of the reason I'm fitting one. When swapping in a heavier engine it doesn't hurt to put it on a diet.
>>27592805Things you wouldn't have to worry about if you'd done things the right way around and chosen the 2 litre S motor powered version of the AE86 in the first place.
>>27592781you do have to be smoother with the throttle but thats the whole point.
>>2759281086 is significantly lighter and has a million times better aftermarket. Besides I've already got a v8 celica.
>>27592851hahaha why you talking in lbs bra>significantly lighterRemeber this picture when you get your rego certificate and look at the tare weight
>>27592867and I forgot the picture
>>27592867>1500ok now where's the same data sheet for the 1500 ae86 aka ae85?
>>27592882I want you to weigh your own AE86 when you get that BEAMS in and think about how significant the weight savings are.
>>27592869>>27592932Now that i look at this more closely. This data is for the toyota carina, not the celica. What's your game, nerd?
>>27592950That's right buddy, even the 4 door sedan version of the Celica is still not significantly heavier than your meme machine.
>>27592983The 4 door rx3 is lighter than the 2 door so don't assume. All this time you've been using a spec sheet for the wrong car. wow.
>>27592983on closer inspection the 4 door carina is lighter than the 2 door as well
>>27592998it's literally the same floor pan lol
>>27592869>Lightest AA60 coupe with 1500 engine: 965kg>Lightest AE86 with 1500 engine: 855kgThat's a 13% increase in weight it's significant.
>>27593088>Your AE86: 950kg>(You): "I didn't waste tens of thousands of dollars I swear!"
>>27593091>4ag celica is 200kg (21%) heavier than 4ag ae86Uh oh I don't feel so good ae86 hater bros
>>27593161>comparing to the IRS model with all the bells and whistlesAs we all know IRS is worth the extra weight, but if for some reason you wanted run a live axle T series Celica for weight savings you could. This Celica already has an S motor in it and it gets as low as 980kg - I wonder how much your AE86 will weigh once you're done?
>>27593197>this celica>using the chart for a *different car* to make some point about the celica again.You slimy rat. Not this time. Why someone so obsessed with the celica doesn't have spec sheets for the celica is bizarre.
>>27593205That's >>27593197 an SA60 Celica you brainletRemember that weight figure when you get your rego papers
>>27593208No it isn't you've just cropped your spec sheet for the toyota carina 4 door sedan. There is no SG celica.
>>27593211Ah right, I made that pic the last time we were having these discussions and didn't check.Celica gets down to 1,005kg
>>275932151,015*
>>27593221You going to make me go straight to the source to argue about 10kg?
>>27593243You're really making me do it, as if that extra 10 kilos would've been the difference between "significantly heavier" or not....
itt niggers arguing about cars they cant afford and will never own
>>27593311Sorry little zoomie but some of us were adults when 80s jap cars were just 80s jap cars and not unobtainable classics
>>27591122lol, lightweight flywheel is not made for getting rid of total weight, its for its engine character change. if you are trying to drop weight, this is only a bonus not something to get the lightest possible.too light will cause driving characteristics to be different. for a street car, it can easily be too light.
>>27591229Are you implying diesels can't go fast?
so how light is too light? For a small diesel engine? How would it exactly change the driving characteristics? Assume that its impossible to stall out in first gear no matter how retarded you treat it.The flywheel in my truck 98lbs, twin disc with a mid plate. It only puts down 1321ft/lbs of torque so its probably overkill to have a twin disc.
>>27594440>for a street car, it can easily be too light.You can't drive and you drive like a bitch
I have a bmw f87 m2 with a lightened single mass flywheel. It's fucking terrible pulling away from a stop unless violently launching it. Throttle map/sports mode makes it worse. Great between gears
>>27594784your that ricer with the fart can blasting cause your super light flywheel has you taking off at 3k rpm, buring up your clutch. you know nothing john slow.
>>27595509>taking off at 3k rpm, buring up your clutch.you cant drive
>>27594778>The flywheel in my truck 98lbsgod damn
