i got a cattman cai and a greddy catback, so now i am buying a clutch and light weight flywheel. nopi had a centerforce clutch (30% increase over stock) for $230. they also have an unorthodox racing flywheel that's like 5 lbs. i will prob get it, but i thought i'd check with you guys and see if anyone knew anything about it...

oh, and the price on the flywheel is $538.08.

any help would be greatly appreciated!!

 

super light.
The stillen one is about 11ish
oem is like 17 if i remember right

 

I would like you to explain to me why you want a lightweight flywheel. (others be quiet). I think too many people do this for hte wrong reason.

 

your right others do it for the wrong reason and about the centerforce, scratch that idea and get an ACT, all other org.y members will agree.

 

You can get a Mueller flywheel for about $100 less (Stillen, other sources). Mueller is a well known and reliable company that has made these a long time. I love the ligher flywheel and don't feel there has been a downside, and I drive in San Francisco. As for the clutch, nix the Centerforce. If you were racing with high revs maybe that would be a good choice. ACT has a great reputation. When my clutch died, I couldn't get one because they were out of stock on pressure plates and a month+ away from production. I got a JWT stage one instead, which has similar specs, and I've been very happy with it so far. The combination flywheel and clutch put a lot more power to the ground, so I did notice more wheelspin letting the clutch out in first. The Quaife fixed that

 

I would like to get a flywheel, but I don't think $500+ is a good price. I believe Fidanza has one for $370 at Ptuning.com The ACT clutch is for going for $304 shipped through groupbuycenter.com
I think dollar for gain, I'd rather get the Quaife differential.

 

I think these all work synergistically. The clutch upgrade is a no-brainer if you have to upgrade anyway, and that's the time to do the flywheel (if you could do the Quaife at the same time, all the better for saving money on labor). With the clutch/flywheel, you'll need the Quaife more because you'll have more power to the ground. I was losing much more traction with the clutch/flywheel upgrade, but with the Quaife I have almost no wheel slip (sometimes there is a touch then it grabs). You could get a factory VLSD for about $1750 (list is around $2200, but I priced it through a connection once; this is exactly the same price as a regular trani) and swap that in. It would cost about the same as getting a Quaife and installing it. Frankly, most shops nowadays don't repair tranis, they just replace them. It can be a PITA to find a shop that will actually work inside a transmission now.

 

I remember a hondaboy bought and installed an ultra light flywheel for his civic ex. I warned him not to but he did regardless. He has no power mods...after the flywheel was installed, he couldnt get enough momentum moving to actully disengage the clutch without stalling out! I think he had to rev to 3.5k-4k to even move on a flat road. no torque hahahahah. that was a funny sight. the best part was....he asked...why does it feel like this??@!!@!?

 

Well, we have nice big torquey engines. That makes a difference.

 

okay, look. i want a flywheel so that my engine will pull harder at higher rpms. i figure when i'm racing, i never get below like 4k, so if i have a flywheel, it will move my lowend power to highend, and thus allow me to haul more *** down the track (or street, as the case usually ends up here...) anyway, i might actually reconsider since i have plans for a 75 shot as soon as i get my y-pipe. dunno yet...

anyway, i really hate to admit my reasoning for the centerforce clutch, but i used to own a trans am, and that was the clutch of choice then. the one i am talking about is a 30% increase over stock wich should be all i need considering my mods: cattman cai, greddy cat-back, 75- shot NOS (soon), and a warpspeed y-pipe (soon). AND i know centerforce has been around a good while. i might get the act clutch, though, if somone can give me a good reason to choose it over the centerforce...

...oh yeah, where the hell did the differential discussion come from?? i asked about a clutch and a flywheel. i am not getting a differential.

anyway, if anyone has any USEFUL info about whether or not i need to get the lightweight flywheel, let me know!!!

thanx!!

p.s. i ran a 9.48 at the track last sunday!!! (that's 1/8th mile)

 

Centerforce use centifugal force to work at full potential, so they require rpms. From what I've heard, they don't hook up as well off the line or low rpm (shifting).

 

I hear the flywheels' benefits really come in 1st, 2nd, and some of 3rd. 4th and 5th aren't really all too noticable. It simply just removes rotational mass and will lessen the degree of enertia...which when you think about "object in motion wants to stay in motion and stationary objects want to stay stationary," makes sense that engine braking will also kick in faster.

I must admit that I started the differential talk. I just think that you'll get a broader range of benefits from traction, handling, straight-line, and therefore efficiency with no adverse effects. Plus it's guaranteed for life even when raced. I think this will be my next and last mod.

 

My 2-cents is the clutch, flywheel, Quaife ATB differential, and poly engine mounts, not to mention your tires and suspension, are all part of a SYSTEM that helps put power to the ground. These are installed in such close proximity to each other that it makes sense to have as many as possible done at the same time. (A big savings in labor may result.) And the more items in the system you upgrade, the more power you put to the ground. And sometimes, due to a resulting synergy, the totally upgraded system performs better than the sum of its parts.

I delayed some installations until I had funds available to complete all the related upgrades in a system. The delays gave me more time to research and plan. And installing everything at once saved big money from time to time. And installing everything at once made for huge, obvious increases in performance! Most of the time, the delays seemed to be worthwhile. Good luck.

 

Very sensible. Well said. Due to circumstances I couldn't do this. I broke a driveshaft and that took out my old trani. The Quaife was still a couple of months away. I went ahead with the flywheel and clutch (f/c) at that time because I was in the system anyway, and that let me see what those changes did alone, then what the Quaife added to the equation. The f/c put more power to the ground than my sticky tires could hold. The Quaife brought the traction back, plus some. The engine mounts vibrate at idle more, but give me better launches so I can use all of the above.

 

guys, i really do appreciate the info on the subject. i don't see the need for the differential at this point, seeing as how i don't have enough power to have a serious traction problem...yet. i don't think i'm going to get a lightened flywheel right now because i plan to spray it VERY SOON. this week i think i'm going to order my ACT clutch, and a warpspeed y-pipe, and maybe an adjustable fpr. after that stuff comes in, i will put all that stuff on, and install all my gauges. that's about all i plan to do to my max right now. i'll have a nice looking car with a finely tuned engine that breathes well and is controllable as far as air/fuel goes, that's about all i want right now!!

thanx again for the info! (and if i have any trouble with a mustang, i'll holla at ya'll for some backup!!)

 

Reviving an old thread, how did that ACT work for you? Which one did you get and did you have alot of chatter?
