you're kidding right?
a lighter flywheel is great for a SC'd car. not for a turbo though.
different things. A SC creates more drag on the drivetrain, so IMO it is a very good idea to use a lightened flywheel. Turbo should stick to stock or barely lightened.
I can't say anything about my 6.6lb one obviously, but I can say that the 12lb lightened ACT stock flywheel I have is not light enough.
Plus I don't even have the drag of AC or PS cause they are removed.
lighter is better.
course everyone has their own preference. and not everyone double clutches either I guess.

sjoback - I agree with Lund. Extremely light flywheels are great for autocross but not for drag. I would not advice running anything lighter than 9-10 lbs for strip/street.
-
ok ok well if you are talking drag, then yeah don't go too light.
I must think too much about daily driving/shifting etc.
I think they (lighter) are nicer for street anyway. Alot of it is preference and tolerance.
I dunno maybe I am just a lightened flywheel FANATIC!
Can't wait to get my fidanza in.

OK boys... here again is the proof !!!
We can all speculate as to what "dynamics" are affected by a lightened flywheel... and we can talk physics until we are blue in the face.
Here is the bottom line:
I made four passes with the standard flywheel. I then changed the flywheel to a Fidanza aluminum flywheel and made four more passes. My average ET dropped .17 seconds (the best being .24 seconds faster). Interestingly enough, my trap speeds did not increase. In fact, they averaged about 1mph slower than with the OE flywheel. Also, all of the time was gained in the first 1/8 mile... the 60 ft times remained the same.
This simply tells us that we gain the ability to accellerate the motor... thus speeding up the gear to gear times. Less energy is required to spin the motor. Unfortunately, there is less mass to peretuate the rotating motion at high RPM's, so more HP is used to drive the motor... this is the reason for the lower trap speeds.

Jim,
How light is your flywheel, Like I said in earlier Clutch Specalies said to use their 8.5 alum. flywheel. Do you think it would be a wise investment?? If not what weight and kind should I use. I have to buy sometime soon my clutch is make all kinda of noise.
thanks

Sorry, your thoughts on the quafe diff. or any other diff would be great as well...

Nick,
I have the JR/Fidanza flywheel. It weighs about 8 pounds.
I have two other Supercharged cars that I have installed flywheels on (a '99 GSR and a '94 Del Sol DOHC). Each of these has a JUN 11 pound steel flywheel, and their 1/4 mile improvements seemed to be less than mine, but their trap speeds did not suffer. With that said, my recommendation would be that if you want better accelleration and 1/4 mile times, LIGHTER IS BETTER. However, if top-end power is what you crave, HEAVIER IS BETTER. If you want the best of both worlds, get the JUN 11 pound flywheel.

Nick,
As for my recommendation on the Quaife LSD...
GET ONE !!! It is money well spent.

How about a lightened GSR one? I believe it weights about 14 or so pounds. If I send C.S. my factory one they said the can lighten it (14pounds) for about $150, or I could sell them my old one for $50 and but another factory one for $300 after $50 credit, or third and final is to buy the 8.5 alum. for $350. Which is the best way to go. Also do you know where I can get the Quafe diff for cheap?
thanks again for all the help

i got a jrsc gsr and i wondering whats the best flywheel weight for street and draging?
