CENTERFORCE Stage 1 or 2?

Post by **240SXer** » Tue Sep 24, 2002 4:10 pm

I'm getting my transmission rebuilt so I think i'm gonna go with a new clutch too while the transmission is appart. I've heard nothing but good about centerforce. The only thing is should I go with the Stage 1 or Stage 2? The Stage 1 holds 30% more than stock and has a stock feel, the stage 2 holds 60% more but probably has a unstock feel. Which would be better for a 240SX with LSD with intake, exhaust, cams, pullys, headers, etc. I doubt i'd get more than 30% of stock power but maybe, but I want it to last long. Suggestions?

Thanks,

David.

Go with the Stage II. It still has a mostly stock feel to the pedal (you get used to it quick). Plus its good to know youve always got the extra room to go.

Take my advise and don't go with sensless force, it's a joke IMHO. We had one on Jay's car and it started slipping within 2 weeks. Now he's running an ACT clutch rated at 267ft lbs and he's doign over 400 and it still dosn't slip! For the money you can't beat an ACT street clutch.

i agree with paul ( i think i just said that;) ), I had better experience with my old ACT clutches than any of the other i have used. Right now we have a special price for the ACT Street disc, and Pressure Plate, email or IM me if your interested...we have them in stock...

The ACT clutch is going to be one of the best clutch engagement, and clutch pedal feels that you will find...a lof of the clutches on the market have their good reviews, and bad reviews, but i havent seen any negativity about the ACT clutches as of yet.

Great clutch for the money.

btw, i have gone through 2 centerforce dual friction clutches, wasnt happy with either of them, got about 300 miles out of my first, and about 20 miles out of the 2nd one on my Sr....i have had friends that had experiences with them literally breaking within the first week...I do know people who have been using them for 2 years with no problems also....but like i said, i never recommend centerforce or spec clutches to people..

Well i must be one of those people. You always hear about the complaints, never from the satisified customer. Ive had my CFII since march and i have not had a single problem or even the slightest concearn it might fail or slip or anything.

Where is the best deals on a ACT that is rated at 267Ft/lbs of torque?

I keep hearing that it holds a hell of a lot more and I plan on going as far as 320RWHP.

Post by **I H8 UR DSM** » Tue Sep 24, 2002 4:10 pm

$279 for the disc, and pressure plate from me. Dont know what else you can find...

I think ACT is located here in Lancaster. Infact I know they are. I'll give them a call and see what they think. I can even drive down there (probably 5 min away). That would be better because I can drive over there and complain too.

I talked to ACT and it looks like they are the way to go. I'm gonna get it from them directly, they're gonna give it to me for about 340 after tax. Which isnt bad I don't think. I'm also thinking about getting a lightended flywheel too. It looks like they're around 400 bux. I'm not sure if I can come up with that kinda money or if it's even worth it. What do you guys think? I've seen an 11lb for our cars? What is a stock one?

I believe stock flywheel weight is 28lbs. Heavy suckers, no?

Post by **240SXer** » Tue Sep 24, 2002 4:10 pm

Humm.. 28 vs 11. I guess it is pretty good. How about getting the stock one lightened? is there any problems with that? I've seen a company that will do it for 150.. Is there any other problems with a lightened flywheel that I should know about? Any reliablity problems, etc.? Is it good for a nice street/commuter car?

Is the clutch they they retail at $330 for the 91-95(91-94 really) the same clutch that we've heard rated at 267FT/LBS. of torque?

It is written as a HD model clutch and the price sounds about right.

centerforce is good but you just have to break it in I have a stage1 centerforce but I am not that impressed with it go with a dual friction you can't beat it

I recently installed a spec stage II clutch and id recommend it to anyone, i love it, ive heard other people complain about it, but its usually the s13 owners that i hear have problems with it, the s14 owners dont seem to have any kind of problems with theirs, i installed mine into my 98 240sx and downshifting into 3rd at 65mph will bark the tires, first smokes the tires silly if i want to, second slams in really good and paints a patch of yokie rubber to the pavement, i love it, have no regrets, i paid 279 for it, no shipping charges from enjukuracing and received it in 4 business days, not bad.

go with clutchmaster clutches... they will not dissapoint you...

Post by **240SXer** » Tue Sep 24, 2002 4:10 pm

I'm thinking about getting my flywheel lightened, but I can't figure out if I want to or not. It's hard, some people say to some people say not to. I want it to be very drivable. I was thinking i'll just get maybe a few lbs. taken off of my stock one. What do you guys think?

do what you want i guess, i told you we are selling the ACT disk and pressure plate for $279 for 91-94 240sx, but if you want to pay retail....thats all you i guess...doesnt make much sense to me, LOL....If you want, i can mark the price up to $320 and you can buy it

:rolleyes

My clutch is starting to go and when I replace it (I'm thinking ACT Stage one?), I'm going to get the 11 lb flywheel...thats almost 20 lbs lighter than the stock one. Anyway, my question...what will the flywheel do for performance besides take the load off the crankshaft? I heard it just lets you rev quicker and frees up horsepower, but I've also heard it decreases torque (or makes it feel that way?) whats the truth behind this? ThanksMARC

I hear that if it's too light it's hard to drive and hard to shift because the rpms drop so fast.

DO NOT LIGHTEN A FACTORY FLYWHEEL! it is a huge potential hazard, esspecialy if your going to be putting in a heavier clutch, and driving hard! lightened factory flywheels are prone, and known to break! as in fly apart! as in destroy your trans! as in try to cut your legs off! its a bad bad route... if you want a lightened flywheel get one, dont rig onealso... what i know about lightened flywheels is, the gains: less parasitic loss, faster reving, and slightly faster acceleration.cons: engine has a tendency to fall out of its powerband or even stall out if you let the rpms drop from high up. this i easily got used to in my beetle, and i assume you would too. you will probably feel like your engines lacking some low end because its probably going to idle a little lower, but i cant see any reason why there would be a decrease in torque.i was very happy with my lightweight flywheel in my beetle... i loved having it, and i recomend them... but they are expensive. also... ACT is the only way to go with clutches IMO and I H8 UR DSM has a hell of a deal on them right now!-pete

Post by **MarkEmark** » Tue Sep 24, 2002 4:10 pm

So if a really light flywheel would do all the cons you mentioned, is there any company that makes like a semi-light one, like 20 lbs or 19lbs instead of 11??

Post by **ser chicken** » Tue Sep 24, 2002 4:10 pm

i think maybe i explained poorly my point... a lightweight flywheel that is a forged aftermarket part is good, and strong because its made of lighter material and its structured to be made thiner. but a stock flywheel that has been lightened is prone to break, because its made of thick brittle casting and does not have the structural integrity to be cut down.as far as an aftermarket manufacturer that makes a mid weight flywheel im not sure... your gonna have to do some research on that... sorry-pete

Post by **240SXer** » Tue Sep 24, 2002 4:10 pm

Racetep.com says theirs have never failed. Only ones I see are 11lb, and I don't want it that light, I want more like 18-20

if you dont want to go all the way i would suggest not going at all... 240's rev fine as it is, and they drop revs well too. if you really want to cut the weight that little bit, then the only way your probably going to do it is to cut your stock one... but i dont recomend it. what i have been told/seen is that they fail... and when they blow apart you better have a second trans... and quite a few other parts... possibly legs... the speed the ring gear is traveling at the outside edge of the flywheel is (2pr)rpm (p=pi, r=radius). so assuming the flywheel is 14inches in diameter and the engine is revved at 3500rpm at a state of failure, the outside of the wheel is spinning at 12,888ft/min. if a piece broke off at that speed it would have a very good chance of not only going through the bellhousing, through the body. but also, assuming the angle is right, through parts of you.the decision is yours... i just dont want to see anyone get hurt because of something like that.i will point out again... lightweight aftermarket flywheels are made of different materials and made in different manners. they are stronger then stock and built to handle the loads and stress of high powered engines while being significantly lighter.stock flywheels are standard cast steel. they are built to be heavy... they are built to be solid and thick. lightening them makes them weak. making them weak... well... re-read the first part of this post.i suggest staying stock or going aftermarket... but thats my opinion. if you do lighten your stock wheel.. i wouldnt suggest too many drag launches on it.-pete

p.s. having legs is a nice convience.

Post by **matt240det** » Tue Sep 24, 2002 4:10 pm

how about a jun flywheel and ACT 6-puck unsprung disc can't wait to try that in traffic:ylsuper

Post by **ser chicken** » Tue Sep 24, 2002 4:10 pm

lol... sounds like after one good highway traffic jam your gonna have one helluva strong left leg!

Post by **240SXer** » Tue Sep 24, 2002 4:10 pm

What if I have it only lightened a little, like from 28 down to 22? Would the still keep the strength?

David.

Post by **MarkEmark** » Tue Sep 24, 2002 4:10 pm

DONT LIGHTEN an old, cas iron, rusted flywheel. Either get the 11 pounder or stay with the iron one.
