Exedy Racing Clutches

[matt dunn]

I have had a few clutches through my car on the 212mm flywheel.

I sent the flywheel to Autoclutch in Auckland and the made a custom one to suit with solid centre and 6 puks to suit my 1600 turbo motor.

Since i have had it it as been the only one out of 4 or so puk clutches to last and to hold.

I kept it when i sold the motor and got a flywheel for my 7AGTE to suit that clutch and still run it, and it get hard lauches and quick gear changes all the time, still hold back the 450hp.

Has been in my car for two seasons of racing now and still looks mint.
And best thing is the pedal just feels like a standard 20V road car, no heavy pedal or anything.

i think from memory talking to you way back when that it was aroudn the same pressure as mine matt, maybe little more.

they are a great bunch of guys there, and mine has also held a poo load of punishment, i built my car to go fast and drive it hard, and i do, and the clutch just keeps taking it.

was rated for about 450hp atw. they reckon, bites like a mofo too i just had to get the slave cyl sleeved with the bigger pressure rating which is why i think they are full of sh1t that you run a 3000lb plate and dont have to do what i did,

can take it to autoclutch and they can test it for you

In saying that, my car KE70 never had hydraulic slave or master,
so they have been retro fitted from something, but not sure what.
I believe the slave is a W5# series from a cressida or similar though.

Yeah I rang Autoclutch as I've had quite a few clutches made by them and they said they couldn't make one to hold the power I want to make (which is less than you guys) so alittle surprised - especially as they made my last one! They were pretty set on selling me a quartermaster thou - so it was probably all about the up sell.

Will do. Will be nice to see if the people I bought it off were talking out their asses or not.

yea same here, I dont think you can ever get a 3000lbs in 212mm and also in the 4agze 225mm, the most I could ever get was around 2000lbs. Due to the design of the pressure plates.

mmm I just going off what I asked for and what the guy told me he had in stock. Said on the box 1300kg = 2870lb roughly 3000lbs

Any place you can take them to get it tested?

If it were 3000lbs on a 4age slave cylinder you will know that the pedal will be ROCK hard like mine. Mines about 3000lbs in my twin plate!!!! i cant see that having 3000lbs at all.

Even look on the exedy web site I sent, no stage 2 clutches are 3000lbs, only the twin plates get up to around that.

Believe me I went through this exercise when trying to find something to suit my power. Exedy dealer in NZ had nothing for me other thatn the hyper spin version with 2200lbs and the twin plate, but they were too $ for me and a quartermaster was a much better price.

Not that I've dabbled in those baby engines at all

But this is what I picked up from Trade Parts in Wairau for about $700 approximately 3 years ago. Held clutch kicking in 1st through 4th behind the awesomely underpowered 1G... 236mm flywheel.

Id get a price on the hyper single clutch that exedy do.

If thats too much, my setup costed around $1700 with a new flywheel and a custom bearing hanger for the fork.

Now i've done hmm lets see 2 years worth of drags, every night wars, rotary nats, import battle etc, I got at least 7 runs per meeting. I've done 5 track days now as well.
Clutch still feels the same as the day I go it . Twin plate FTW.
To me thats a pretty good investment. Not having to ever have to worry about changing ur clutch.
I also drive it on the road and done over 10,000kms with the twin plate.

If you do go twin plate, you need to get the rally pack one. The normal ones will just wear out superfast. Rally pack is able to handle the abuse as the plates are much much thicker.

easier to change driveshafts that clutches

Hyper Single is around $3k retail - definitly not going to spend that much.

Dang LOL. Thats more than a twin plate lol.

Why not get a twin plate stu, it will last forever.

In saying that Brendons puk is doing ok, but we need to do more meetings with drags tyres to see how long its gona last.

Edit on that - got the price down to just under $1500 for a hyper single.

[IH8TEC]

for that price, still be better to go twin plate i reckon, and not have to change it as much. but yeah up to you. how much power you planning on making?
