at your own peril, have warned you about torque

whats the point unles revving the balls out of it

which your not going to, and balanced engine

To keep it on cam I'm going to have to rev it quite a bit so the flywheel should be suited for the engine shouldn't it?

why do you want a lightened flywheel with only 75 -80 bhp at the flywheel

if i was building an engine to rev 6000 - 7000 or more revs all the time yes

but your only putting in a 276 and you said yourself wont be revving it hard

if only you were closer you could have a drive of mine

i nkow a lightened flywheel sounds nice but i tried it, and it came off

my slighty modded mg metro the next DAY

[jamiestevenbell]

i personally would go for it i think it will be fine and i must hav got mixed up with another thread on here

as far as im concerned from EXPERIENCE bad advice

well im speaking from experience as im currently running one in my engine with a 286cam on a 3.44diff and it has plenty of torque i can be doing 45mph in 4th and it will pull fine dont get me wrong if i wanted to boot it fast i would drop it down a gear but i if im driving normally i can leave it in 4th and it will pull nicely, i dont think the torque will be a problem at all

have you done a back to back test as i did ( modded mg metro)

the car was slower with the steel lightened clutch assembly
if someone was to offer me a brand new assembly in would not
go on my car only revving to 5500. fine if you want to rev to 7000
and got the horsepower and high cam say 90 - 100 bhp plus

wheres cooperman !!!!

[racingbob]

oh missed something out

it was like all rev and no GO

[jamiestevenbell]

how would your car be slower it doesnt change ratios or any thing with the lightened flywheel? It will just spin up faster, i havent done testing but am speaking from what i have in my motor, you will loose abit of torque but i think you will be fine

[R1minimagic]

Why would you lose torque?

[racingbob]

i give up !!!!

[R1minimagic]

Good idea!

[JustSteve]

theoretically I don't see how a lightened flywheel can be slower, lose power or torque..

the power/torque comes from the engine, pistons, fuel, bang... a lightened flywheel isn't going to slow it down, but it will make it accelerate faster, but carry less momentum.

Surely, the only disadvantage other than a lumpy idle, is going to be in trafic and at the lights. You will just need a few more revs.



Am I mising something?

I just wish I knew what any of you were talking about! All I know is that if you put your right foot down the car should go quicker.

[Alex_B]

The way the flywheel adds torque i belive is by adding inertia, the heavier mass spinning of a normal flywheel will need more power to spin it but with also spin harder in a way, and by lightening it it looses inertia faster, thats the way i see it anyway, if you have some LEGO technics about then rig up a big heavy wheel and spin it with a couple of cogs it will take more power to spin but will have more torque.

Exactly right!

The idea of a lightweight flywheel is to improve acceleration and that is exactly what it achieves. It has no effect on engine maximum torque whatsoever.

one more word

just put it on dont take any advice on a BACK TO BACK test i done

[JustSteve]

just put it on dont take any advice on a BACK TO BACK test i done

do you have any figures or anything to prove what you're saying?
