where is the best place to buy and which one?
5 speed gearbox

 

Your 5 speed gearbox will let not handle anywhere near that sort of power. Unless its a dog leg box or something of that type.

 

As performance

 

Helix twin plate same as in mine

 

I would agree that 650 is twin plate territory. Although someone on SN was advertising a six puk single plate that he reconed would do 700.... Hmmm

 

Dog leg? Or straight cut dog engagment box?

 

Exedy Hyper D-Core Twin plate

 

CG motorsports are offering a twin plate clutch for £500

 

Exedy twin plate RCM.

 

Yea act extreme do loads wether it a act,exedy any thing best price be from as performance with great knowledge to follow

 

ACT single plate

 

Hi Budgie, what 5 speed are you using that can handle 650bhp and what gear set does it have, any idea of what the torque rating is.

Please.

 

Pffffff.

 

600ft lb? How heavy is that pedal lol?

 

It's fine mate Iv driven one same as team legacys time attack car and Andy forest I would say it's pretty tested.
Lighter than my twin plate i say

 

Not as heavy as you think, They have been tested very well by lots of people running big power, I know a couple with them in road card with around 450-500lbft...Not far off OEM really

 

How have they engineered that then?

 

Running an act extreme paddle in mine, is ok for road use, the organic would be slightly more road friendly but it's not a daily so it's fine.
Was thinking about a twin plate but really couldn't put up with the noise and would be right on the limit at this level and a triple is far too expensive and even noisier, so paddle it is.

The act extreme is rated to 725 ft/lbs from memory, I'm around 570 so still got more room
