Npc Performance Clutches! Thumbs Up!

[colourclassic]

Just got my NPC Organic 10" installed and the pedal feels like an N15 pulsar's - light as. Still wearing it in but so far it feels really grippy and easy to use. A lot better than the Exedy that came out, which was slipping at 250rwkw and felt like doing a 40kg left leg press.

My NPC Organic 10" is a rebadged Exedy unit (or vice versa), even the part numbers match. So my assumption is that a new Exedy would be just as good as a new NPC with these specs

[Hadouken]

Sure. If you are that way inclined

nope, NPC uses Exedy parts - however their clutches are modified with different friction material and their pressure plates are modified in house.

A normal Sports Organic or Ceramic (silver pressure plate) clamps less than a NPC and the pedal effort required to disengage the clutch is heaps more.

Doug from NPC (I believe through rumours) used to work at Exedy and took his knowledge to NPC.

Yea the Exedy had the silver pressure plate and was about 10 years old. Nothing wrong with it, but soo heavy compared to the NPC!

[dori34]

anyone use the 9.5" NPC clutch or are you all using the 10" as advised by NPC?

[MrStabby]

AFAIK there's no upside to using a smaller diameter clutch, so i'm guessing everyone's using the 10. That's the one i'm using.

[colourclassic]

10"

[Hadouken]

almost everyone uses the 10"

[iruvyouskyrine]

Less rotation mass

[dori34]

cheers just placed an order for 10"

[Hadouken]

Very good

[MrStabby]

Less rotation mass

Oi! No nit picking or we'll have to start talking about moments of inertia.

[boostn0199]

Good clutch worked well but doesnt last too long under heavy abuse compared to my previous exedy HHHDB but trade off is its easy on the box lasted 11 drift events roughly 1 year HHHDB lasted 2.5years and still was working when removed going to move up to the twin plate super coppermix competition now.

[Hadouken]

Hmmmmm.

I've had 3 track days

About 60 awd launches

2 skid pans

And 3+ years of street driving/traffic

All with 340kw.

[jay-rod]

Same, mine has had over 80+ rwd launches

1 Very very bad launch at the drags which was rode mistakenly.
( had to let it cool down after that )

Many many track days, 2 1000 meter runway events

going on 2 years now i think from memory

My last 3 clutches before that where both Exedy Organic's HD

1 did ok...but that was around 300 hp.

1 fried it self after a couple of months

The other literally snapped the pressure plate.

My mate also same clutch, broke 2 of them, 1 was the same Pressure plate snap.

Exedy where awful when it came to asking wtf happened when it was sent back.

Got " you change gears to fast " ......really....

Never buying exedy again.

[boostn0199]

Yeah i guess difference is in my use its cinstntly clutch kick 3rd 4th gear consecutively as appose to drag doing 1 launch then it has time recover and cooldown or circuit driving its proper shifting. But like i said definately good clutch in terms of what it can take for such a low camping force and does save boxes.

The only exedy that is good is the hhhdb clutch disc is identical to the npc with only diff having a massive 1500n clamping load pressure plate lol but rest of the mild exedy clutches dont take much abuse.

[dori34]

NPC boys must be pretty busy, having trouble getting in touch with them and to place an order...

[Hadouken]

It's probably due to all this free advertising
