ORC Heavy Duty clutch + Lightened Flywheel on DC5R - Easy to live with?

[Nuci]

Hey all,

After having my DC5R tuned to make more power, I figured clutch and flywheel would be a good place to look to next. Ive heard good things about ORC, and so im thinking this is the brand im going to go with.

However the car is my daily drive, and I wanted to know from people's experiences, how a heavy duty clutch and lightened flywheel from a company like ORC affects driveability? My previous car had an exedy heavy duty clutch, but im guessing that the ORC parts are a bit different. What are the pros and cons of an upgrade like this? Worth it? And is the improvement in acceleration noticeable?

Any help would be great. Cheers.

ORC is nuts. I'm sure you'll get used to it though, but it's pretty tough for day to day if you're not up for it.

What sort of power are you making? Even with 150kw at the wheels I never had an issues with the stock clutch.... If its not broken don't fix it...

It's making 135 kw at this stage, but I have plans for more power later down the track. I just figured a better clutch / lighter flywheel would make for quicker shifting and better acceleration. The heavy pedal doesn't worry me too much, it's more whether the car is going to become jerky and harder to drive smoothly, escpecially in like 1st and 2nd gear where there is the most engine response.

Questions:
- What engine mounts do you have?
- Are you ever planning on changing the final drive?
- Is the ORC HD clutch a full faced clutch or does it have seperate pucks?
- Do you have a link to the particular clutch you are after?

Thanks

After the clutch invest on new engine mounts, they will go weak.

you will love the clutch, I heard the new ones have a very soft pedal to it, but engagement is still grippy.

I have the Hasport street engine mounts. Not planning on changing the final drive at this stage. If by separate pucks you mean single/twin/triple plate, I believe its a single plate clutch, with a 3.8kg billet flywheel (Model ORC 309D).

Here's a link to it on the JDMyard website: http://www.jdmyard.com/catalog09/ogura-racing-clutch/

Yeah already got Hasports. And I've heard the same thing about the light pedal, not like the ones made here where they're heavy as.

Yeah true that, my mate has the old one in his B18CR eg and his brother has the new version one in his VTiR Integra. EG guy is cutt as because of how soft the pedal is.

And it still makes those cool sounds when clutch is engaged. Still has that grippy ORC clutch feeling.

But beware there are still some suppliers selling the older version I heard... theres nothing wrong with it, just that heavy pedal.

No, by separate pucks I mean that the clutch face has separate friction points

Below is an example of a 4-puck clutch


These are the types of clutches that are hard to drive with, as the clutch is either on or off.

If it's a full face clutch (Like the one you have chosen), you can still ride the clutch, so it can be used for everyday driving. But it can be annoying in traffic with the heavy pedal, but you get use to it after a while, and it feels normal.

As for the flywheel, the stock AUDM flywheel is about 9kg. The major things you are going to notice with a light weight flywheel are that the engine is going to rev quicker, as it has les weight to rotate from gearbox to driveline. It also looses revs fairly quickly.

Again, you get use to this fairly quickly, and after driving the car for a couple of days you'll think it's as easy to drive as stock. Just rev the car a little bit more then you normally would, and you’ll be fine.

When I first got my Toda clutch kit (Excedy Sports Organic & 3.8kg Flywheel), I stalled the car about 8 times driving around in traffic, but now have no problems what so ever with the clutch or flywheel at all.

Pedal feel is directly linked to the pressure plate / type not the clutch disc or flywheel surface.

Ok cool thanks for the info. Is a clutch with more than one puck also called a button clutch? That's what I thought they were called (button because they were either on or off).

And did you notice that with a lightened flywheel the car was noticably faster under hard acceleration?
