clutch

does anyone know what sort of power and torque a standard wrx clutch can reliably cope with?...and is it the same clutch as fitted to uk and jap models and sti models?

reason for asking is my clutch has reached the end of its life and needs replacing but the car is now running 1.2 bar of boost , so looking for opinions on the best way to go....standard or uprated

cheers
chris...

all of the 5speed 'new-age' cars have the same size/type clutch - the 6speed STi is different!!

not sure about the official type of figures they are capable of, however, we have at least a couple of customers with over 400bhp on a std clutch.................comes down to your driving style/ use

if you're really bringing more power into the car
you may want to change the type of clutch material being used
(carbon or metallic)

my clutches are still organic material , oem style, but i dont have that much power in the rally car

if i were a bit more aggressive with the power being thrown down
i'd probably want to consider different material or even swap to a 3 or 6 puck

here's a link to some scoob spec clutches

oem clutch can only handle 'so much'
if you want more bite, move on to something a tick more aggressive.

The AP organic 'standard' clutch is a great bit of kit and is easy on the leg too. Even so, they are only rated to about 320 lbs-ft. of torque. Many use them with closer to 370 with no problems.

I changed my last engine at 50k of use and the AP clutch was still in very good condition with little wear considering the abuse I've given it.

The standard clutch seems to dislike much more than 320/330 lbs-ft. when used for standing starts and they seem to wear rapidly.
