Fidanza or Stock Flywheel??

[frontierguy25]

Guys currently I have the Fidanza and have welded my clutch twice now. It's mainly because of the Feramic disk that is in there. I am taking it all out today to send to South Bend. Now what I do is daily drive the car for now and drag race when I get the chance. So I was just wanting to know which should I use?

My new clutch will be a 8 puck ceramic and kevlar disc, so I won't have any problems Welding the clutch again.

Thoughts???

8-puck, hmm. Thats a lot of clutch for DD. I would think that with a clutch like that and a light weight flywheel you would lose a lot of drive-ability, for the street. Thats a tough one. Lighter weight means revs come on alittle faster, but your missing out on the bit of rotational mass, which is good somtimes. Fidanza flywheels are said to be real good. Has anyone ever chewed one up?

Fidanzas are discussed in several other threads here in this section, search it bro. The RPS is also a favorite of many.

I have searched and been around for a while. I have the fidanza and have had it for 4 years. It's been a fine flywheel, just with clutch I have now it has welded together because of the feramic disk.

I used to have the RPS Max PP and 6 puck disk, and I'll never use that again!!!
The clutch was shitty to engage and the pressure plate exploded going down the street. However since it was a 6 puck it never welded itself to the flywheel.

The 8 puck shouldn't be as bad as the 6 puck. Just wondering if I should switch back over to the stock FW!

I think you'll be fine with the fidanza. Just make sure the friction surface is in good shape before you stick a new clutch in.(Im sure you would anyway as you welded the clutch to it).
As far as I know, an 8 puck would be more drivable than say a 6 or 4 puck. Most 4 pucks I have ever seen are unsprung and are an on/off switch.

If I keep the flywheel, I will be putting in a new insert for sure!!

Go with the stock I ran the same setup you had the heavier flywheel will help on the street as well as the strip with the heavier flywheel it also makes the 6 puck clutch more streetable I wont go back to a light weight flywheel in such a heavy car

I run a stock flywheel with my 6 puck clutch, it's very streetable. Any yep, the less actual clutch material the harsher the clutch and the more it tends to hold (counter intuitive).

Full face (stock), 8 puck, 6 puck, 4 puck, 3 puck (yep, they're made, and I'd hate to drive one...)

I ran a RPS Max PP 6 puck with this flywheel and it wasn't too bad. I'm going to see if I can source a stock flywheel in descent shape if not I'll just stick with the fidanza.

Any of you drag racers out there what do you use and why?

Duane and a few others all used the stock flywheel so they wouldn't weld the clutch...

I don't trust the RPS MAX PP at all, too many people have killed their motors with it...

Could you please elaborate on how the flywheel destroyed an engine ??

I have had the South Bend clutch for 2 years now. all that I was stating was I had the RPS Max PP and never had a problem with it. I believe it's just because of the full face Feramic disk.

With the new 8 puck ceramic/kevlar do you think that I'm going to weld that?? I had the RPS 6 puck and launched about 50 times and never once had it weld but again that clutch has a ceramic disk.

The RPS MAX Pressure Plate is what he is talking about. The plate is a 3200lbs pressure plate so it makes the motor work harder at start up. Once you press the clutch in you are putting more pressure on the crank, and with a cold start up your oil is thicker and it actually doesn't get to the crank.

When I got this set up what I did was the starter mod where you don't have to start the car by pressing in the clutch.

i was thinking of just doing the hybrid clutch package from a2 with a stock flywheel

i will only have bpu's (full 3in exhaust turbo back and air intake) and dd my car (i might add some other stuff later on for some more power but i don't really plan on it)

but its supposed to hold more power but also be driveable on the dd

Correct, but it's not only during startup. The thrust washers don't have forced oiling, and wheren't even designed to take such insane forces.

My PP is a bit stronger than stock, but if I needed stronger than this I'd go multiplate as it's the ONLY way to get a clutch that holds the power without destroying the engine...though someone did mention somehow making them have direct oiling from the oil passages.

On the clutch, it's up to you. You can try to run the aluminum flywheel, but i myself stuck with stock because I had an extra one laying around that was in good shape for resurfacing, and I didn't want to risk welding the disk...

I run a Fidanza, and I highly recommend the ACT XTSS kit: 2600lb pressure plate with ACT full-face organic street disc. It holds 522ft/lbs of torque, and the engagement is BABY smooth. My pedal is now rather stiff, but easy to get used to and my left leg never gets sore. And not nearly as stiff as the RPS3200. Best price I found was through A2 motorsports, in the vendor section here!

 

[frontierguy25]

Well the clutch that I'm replacing would hold 540ftlbs of tq, the new one will hold a little bit more but also be a full face disk with 8 pucks on it. The clutch will still feel like stock though. I'm not getting and will never get another RPS clutch. They are not worth the money and headache!! I love my South Bend Clutch and they are taking really good care of me on this as well.

I have been running the RPS 3200 for five years now. I replaced one two years ago, new OEM flywheel, Ferramic full face sprung disk. I sold my old RPS to a freind. Its in his Supra, @350tq, stock flywheel, stock disk, no problems so far.

I have welded my ferramic several times now. Hey, but it NEVER slips, right??!! It's a lot better with the brand new FW, but still, it will weld itself, and the pedal is STIFF.

Has anyone used a good multiplate, easy engegement but good hold? I'm building the motor right now with all the best stuff, so she's gonna pull over 400 when finished. But I need to decide on a clutch setup.

Tranny has been completely rebuilt, V3 short shifter and aluminium 1pc driveshaft on its way from SupraSport, so what about the clutch. I know the ACT's are good, another freind has one and he likes it, but he's 'just' putting 350tq down.

Any other suggestions?

Ok, Ive been reading about 'welding' the feramic and even some other clutch discs to the flywheel surface.

Is that mainly under a racing condition where the disc has gotten REALLY hot? We're not talking about, I was daily driving and it welded, right?

Also how to you remove the flywheel if the disc is welded to it!!

The RPS segmented flywheel is the only flywheel I have ever seen that brand new out of the box had different heights from one segmant to another.
Kind of a manufactured wobble.......
Just my opinion, but I think RPS stands for Real Piece of Sh#

Is that mainly under a racing condition where the disc has gotten REALLY hot?!

From having inadequate clamping force on the pressure plate, and having a metal puck clutch slipping under full throttle.
The metal pucks reach melting temp, and 'friction weld' themselves to the other surfaces.
This is typical of the new breed of chinese 33-1/3rd stage clutches.
Bright colors, and big claims don't do crap.
Stick with name brands, and proven track records.
Don't be a cheap-a$$.
Buy enough clutch to handle the power that you plan on building.
