B series Fly wheel Question

[lsi-crvtec]

is there a big difference with the stock flywheel and the 12lbs ones.....My friend is tell me 2 use the stock one cause it gives me more TQ But the turbo will take longer to spool

there is a difference, but you have to go for the right combination. For example, a 8lb flywheel wouldn't really be ideal for a streetcar and you'll have trouble launching the car. Also another issue is that it could affect your powerband a little since the rpms will drop significantly with a lighter flywheel.

Stock is around 19lbs. i believe but just about any machine shop can machine one down to 12...

To keep the rev's up between shifts you just have to learn how to drive ;)

I weighed my stock B16 flywheel & it was 18 lbs .. I've been on my 7 lb flywheel for 2+ years & I've always loved everything about it.

I drive mine daily, I don't have trouble launching my car, & the lightened flywheel didn't have any adverse affects on my powerband; it actually picked up like 4 WHP/TQ cause I had dyno'd it before & after.

x2 i have no problems w/ my 7.5lb flywheel. it only takes about 2weeks to get use to it..well it did me seeing that i didnt drive my car all the time. its my partial daily if that makes sense. either way lightweight is streetable:goodjob:

To each their own. Just going by what i've heard.

[Sammich]

i'm going by what i know

[BlkCD5]

a lot of misconceptions about the issue. I was told i'd lose tq as well if i went lighter, but I have yet to see that.

[Sammich]

in essence you are able to reach your hp/tq quicker. i dont know if you gain hp/tq. it improves your acceleration b/c you dont have '19lbs' opposed to '7.5lbs' to 'turn'...

[Sammich]

you rev quicker..

i have a 12lb...no probs here. i would never get a 7lb flywheel..i have driven cars with both and cars with feather weight flywheels are the loss imho

[Dirty Octopus™]

there is a BIG difference.
i recently got a 8-9lb flywheel and i feel and see the difference it makes.
the car gets up like hell, but i also notice the difference from a stand still and when making turns that may require downshifting.

[Sammich]

yea rpm drops quick like anytime u touch the clutch pedal

[JDM onlyy]

I think I want me a lightweight flywheel...Just need the dang money. Actually I should upgrade to a 5spd first. LOL

thanxx guys......so im going with 12lbs,cause im running 500whp...so thanks

[RISKYB]

i like the 12lb or so lightened flywheels, they are not superlight but you can see a difference

[collins]

i used an 8lb flywheel on my b20 for about a year (or so, i think...) and loved it! the car seem'd to lose a little tq (or so it felt like) but the car was substantially quicker. it'll take a couple days to get used to, as it requires a different driving technique, but its definatly worth the change.

to the OP, your friend doesn't know what they are speaking on.

a lighter flywheel enables the motor to accelerate faster - in that sense it actually frees up some power.

ask your 'knowledgable' buddy if big heavy 22" wheels make the car have more torque too! lol

best of both worlds:goodjob:
