Super Copper Mix Or Hyper Metal

[PaulosECR33]

oright i looked all night last night for a thread which could help me but most of the threads that talk about super copper mix clutched talk about twin plates...

right my question is... over all which is better? from all your experiances with them

exedy hyper metal single clutch or nismo supper copper mix single plate clutch?

exedy hyper single is rated to 400hp with 1200kg clamping force according to website.. found a thread where someone claimed to have 350rwkw using this clutch with no issues

super copper mix is 420 ps (414 hp) and 1000kg clamping force, and i read a thread where simonr32 spoke very highly of single plate coppermix but i could not find power figures...

are these specs engine hp or rwhp? as my aim is about 300rwkw (about 400RWHP)

my other option is a exedy hhhdbc which Hamish uses and speaks very highly of... still going strong with 325rwkw

i know there is a big price difference in the three but i would just like to get a better idea of their performance and what they are capable of before deciding. have chosen these as can get with trade discount through clutch supplier..

any help would be great

Pretty sure those power figures for clutches are at the flywheel not the wheels

then i dont understand how someone could be running 350rwKW through a clutch rated to 400flywheel hp... 400 hp is pretty much 300kw which would mean it would only hold like 250 max....

if this is true then i guess the only option out of the 3 is the hhhdbc as hamish stands by it and the dude at northern brake and clutch also stands by it saying it will handle 330rwkw...

anyone else using either a coppermix or hyper single plates????

HHHDBC will hold more than 330rwkw without a worry... it's definately cheap and nasty when compared to the likes of a nismo SCM twin, but for a single plate that can take that power it's awesome

[PaulosECR33]

yeh i reckon i will go with the hhhdbc i just wanted to see some other results or opinions of the single plate nismo and hyper metallic stuff..

seems as though nobody uses them though lol..

your right about the price its great for a clutch kit that can hold that much power..

triple hbd it is then,, cheers man

[joeyjoejoejuniorshabadoo]

no worries man... report back here when you have it bedded

[PaulosECR33]

will do!

I got my self a carbonetic 5 puck clutch specifically designed for 330rwkw 600nm torque for $380 including pressure plate with strong clamp but no so hard it's on/off.
