Default AP racing clutch power capacity 😕

Hi,
Looking for people's knowledge that have used this type of clutch and its torque capacity/power.

It's a AP racing heavy duty single plate type as sold by burtons etc

Cover item ~ CP3380-2

Heavy duty organic plate item ~ CP2346-70

I'm using a 10 spline input shaft as per mustang gear kit in T5

Cheers

I was told it would start to struggle at around 460hp with similar torque

I guess it really depends on what the car is, its weight, grip level etc.


On average I would think when you start going over the 350bhp/350ftlb mark you should start looking at paddle clutches.

I was told from Antony lane at ap racing the quoted torque of the organic plate is 330lbft..
STD T5 box is rated to this also I believe.

However he side they have engines running at least 400lbs on the above set-up

Car is approx 1000kg. Rest of the drive line supersedes the clutches ability strength wise on paper. 245 rear section rubber

Sounds like a similar spec to my Cortina, I was advised by Harvey Gibbs to use a paddle clutch at 400lbft. I cant see the point of running a normal clutch at its absolute limit.


Paddle clutches aren't really that bad all I would say is seriously consider going hyd makes a huge difference.

Go hydraulic and go full paddle, they're not that bad at all.

I had Ralyand do mine as i was in a hurry and didnt want to piss about myself, how ever if you do your research its not that hard to do it think you use a E21 bmw slave and just weld a bracket onto the bell housing, you will then just have to sort out the peddle cyilnder.

Thinking of using a Range rover P38 type slave as it looks like the fixings for mounting can just be drilled and tapped. Saves having the bell housing welded etc.

I really wouldn't focus on the power ratings that are clamed, I cant really see a single plate clutch being suitable for 600bhp unless the cars running on 13's with nangkang ditch finders.


Its really down to how and what your going to use the car for, just driving round town and the odd boot up a bypass then a normal type clutch plate will properly do, 6k launches at santa pod then may be not.

This is it. .. Paddle clutches wear at a greater rate also, ie road miles.

It's just I don't want a 7.25 inch twin plate as its a road car first up.

However I need something that's good for heavy launches and not shit itself !

Any other opinions out their!!

I found this on escortrscosworth.com



Quote:

The standard AP 6-paddle drive plates are able to take 450lbft for 15,000 (HARD) miles if you avoid launching (which is the killer on clutches and transmissions), so is fine. If you want to do any drag racing or had significantly more than this, you would still not go for the solid drive plate, but then go to a twin plate clutch.....
