I wondering what clutches people were using on big power cossies as i have recently fitted a twin plate ,and toasted it almost straight away
so was looking for options as will so be mapping more boost and dont think a six paddle will hold it. Its a road car ,with some strip action.

 

AP 6 Paddle and Hydraulic clutch from Reyland.

as recomended by Martin himself and engine is on the plus side of 500bhp

 

Twin plates are fine just dont do big launches with them slipping as they cant handle the heat.

have a centre push hydraulic but i will be running 2 bar plus on a gt30 plus gas not sure how well the 6 paddle will hold

 

Is it a Reyland centre push kit? I will be running one along with a tilton twin plate, identical set up to martins car , what twin plate did you have?

 

not sure of clutch kit origon , it a quarter master twin plate managed to over heat it launching ,have got to be more brutal and launch with no clutch slip going to f~ck more diffs and drive shafts though.

 

Not true, the twin plate fitted to my car will take repetitive launching and 800ft/lb of torque but has very nice road manners.

 

well new plates have be ordered with yourself martin , but as mark said and i was told by the main man from quarter master they dont like heat from slipping ,they did show me there carbon clutch but jesus how expensive

 

Was just thinking of putting up a similar post but Kelv's answer covers me

 

My clutch is not the same size as yours... Yours uses 7.25" plates mine uses 8.5"... Having said that my previous car used the same clutch as yours and did at least 10 runs back to back at Brunters resulting in a 2.8 0-60 and the clutch didn't fail.

The two clutches for comparison, the larger one is only available from myself..

 

so your going to run a six paddle , got to be honest mine was running 480bhp plus a shot of gas and holding fine but that was only with 1.9bar of boost going up to 2.4 soon and a bigger shot of gas so whated to be sure it would hold

 

It is true, They will not take lots of slip, Launch correctly and you will have no problems with them, Bodge launch's and you will kill them.

martin is nt the plate with the smaller one a race plate ,the rally plates i have seen look like mini 6 paddles

by the way im not doubting your advice was more looking for options

 

says it all , did not realise how easy they were to kill until i had a chat with rod at brunters,it was to late by then the plates were cooked ,at least its not a big job taking my gearbox out is now a service job lol

 

If you can launch correctly they will last, If you get lots of slip then you need to cool them down and dont do it repetedly.

Mark

 

Pretty much what i was told by rod he said he had killed a couple getting used to them

 

No, the smaller one is a 'rally' type plate. The six paddle version is the AP type.

I only speak from experience but sadly I have only been using these clutches on 4x4's for about 8 years so take what I have said with a pinch of salt

 

as i stated im not in anyway douting your advice as im in no persition to do so ,will be using the twin plate and trying to slip it a little less as i know it was my own fault i over heated it, just do nt like just dumping the clutch as im sick of breaking things

 

Obviously if you slip the life out of any clutch the end result for the clutch is not going to be good! But if you think that I side step the clutch to get results then consider this.. There is a video if me launching my car time after time at Brunters but on one run I manoeuvre the car to get it ready to launch but stupidly leave it in reverse I launch the car but it only creeps backwards about one foot as I was able to detect the car was travelling in the wrong direction, that alone means I slip the clutch off the line! I suppose it depends on how much slip is used.
