Reaction to New ACT clutch and Flywheel...
LOL I always dyno test my performance mods after install. When I get ready to do my flywheel/clutch combo keep an eye out for the dyno thread. LOL

you won't see the change on a dyno.
this is because you will be performing the dyno runs in 4th or 5th gear. In these gears, there is very little mechanical advantage and engine acceleration is relatively slow as compared to the lower gears.
if you were to perform a 1st or 2nd gear dyno, I'm sure you'd see a difference. the lighter flywheel allows to engine to pick up rpms much faster as it has less mass to accelerate and the mechanical advantage of the low gears can let the engine accelerate quickly.
make sense?

Flywheel and clutch combo won't give you extra horsepower.
Which is what some people seem to think here, not saying you do
The flywheel is only freeing up some of the hp or in a sense redirecting power to wheels rather then to some engine compnents like the flywheel. I had a stillen flywheel that wasnt to heavy or to lite, I noticed a diff in accel more high end it was nice

Im getting the ACT HD R6 solid puck clutch installed monday...along with the prolite flywheel. I weighed the clutch and flywheel together on a bathroom scale and it came out to 29lbs. I will be using my car on the street as well even though its not recomended, but im driving mostly highway when i do and im willing to put up with all its compromises. I take my Z out to play on HPDE/TT and that was my primary concern.
I see everyone has purchased the sprung disc, anyone with the race disk? If not, im the guinea pig.

I've been driving my R6 solid puck ACT clutch and pro-lite flywheel for 2 days....I LOVE it...i let a fellow board member drive it too....he thought he wouldn't like it during everyday use....I myself found it fine...it slips enough once you get used to it...and it grabs QUICK...and lets you get through gears so much faster. I am glad i didn't go witht he Street/strip set-up for me.
For reference:
Along with the install i also added the Nismo SS clutch line.

sorry for all the questions, and i appreciate the help.

I would say with the install it is about 40% softer, which is perfect since i hate clutches that are too soft. Its also well to note i installed a new slave cylinder as well.
And yes the SS clutch line was good, and maybe thats why i have such a grippy clutch that i can get just right on, making it streetable tottally for me. I can't wait to hit up my next event...i can shift so much faster...grab and go as soon you hit it.

It might not sound as bad from outside the car as it sounds inside but it still is kind of annoying. My girlfriend might object to it also...LOL. I just want to know what everyone's opinion is on this and if its normal by any means. Any advice is appreciated. Thanks in advance guys.

I just got the Exedy Stage 1 Clutch Kit, and ACT StreetLite Flywheel. The chatter is there but very minimal. It doesnt bother me a bit. Its actually quiter then the stock if you ask me. My throw out bearing made some pretty bad chatter on my stock setup. I also changed to a SS clutch line.
1 Thing I noticed is you have to re-learn how to take off in first as it grabs so quick there is no negotiating it.
Personally I love this setup and wish I would have done this first when I got my car. The engagement point is close to stock and the pressure of the clutch is just perfect.
What do you guys recommend for taking off in first? Reason I ask is because when I try to slip it I get a lil burn smell (clutch is brand new 5 days old). I found a good point to release just wondering what everyone else is doing. Whether you are revving it more or just launching.

im also trying to re-learn how to take off on first, i have the ACT Stage 2 G6 withe the Streetlite flywheel and it chatters till 1700rpms,( not bad compared to others).
I know its been quite sometimes since you guys posted this info and i am glad this post is here, made me go ACT
.....BTW the clutch is phenomenal i just gotta learn the clutch lol ...
besides that i definitely feel more power on my z...

bumping an old thread with a question.
For those who have driven them for some time, would you rather have the ACT Streetlite or Prolite flywheel? (based on drive ability)
