Does anyone know how much power the standard WRX clutch can reasonbly be expected to sustain, and if it is not more than 270bhp which type of super clutch upgrade is IYHO the best?

 

Are there no technically astute peeps out there, some one must have a clue - even if its bumcrack. jj

Awww come on - no fun!!!!

 

FreeT - No idea what its supposed to be able to take, BUT:

Since my power has increased to 285bhp I've been getting clutch slip. I don't know if this is to do with the power increase or simply that the clutch has been on for at least 25 thousand miles and quite possibly the previous 50 as well!

I was recommended an AP Organic clutch that is rated for up to 350bhp which should do for now

 

Clutch slip is a cheaper option than replacing gear sets in the gearbox.

Cheers, i had no idea what it can cope with. Will you be getting an uprated clutch or just replace standard more regularly?

 

a clutch can take any power you throw at it. The torque figure is the important one.

 

That will be why the evos faster - similar bhp but torque higher and accesable from lower revs? And why diesel turbo cars have great in gear acceleration, although noticed 0-100 times for diesel are really poor - dont really understand why - maybe rev limit so low.

 

FreeT, the way I understand it is lots of power enables high top speeds...you need lots of power to battle the forces of drag which get higher as your speed increases but at a non linear rate.

Torque is what you feel when accelerating, hence diesels always feel very strong under accel. Problem is it's more difficult to get more power from a diesel, and hence their peak power is always realtively low, so when it gets to say 70mph and starts to really need some power to get the car powering through the increasing drag, it can't do it. But it can tow high loads cos they have good torque. In gear times for a diesel are normally pretty good, like 50-70mph etc. mucho torque.

Scoobies much torque and power hence so devestating

 

spence7:

That makes sense : comparing 2 bmws 330 petrol v's diesel

petrol 231bhp. 221lb/ft. 0-60=6.7sec. 0-100=16.7sec. top=151mph 1/4mile=15.1(98mph)
diesel 184bhp. 288lb/ft. 0-60=7.9sec. 0-100=22.5sec. top=141mph 1/4mile=16.1(87mph)

Makes petrol look faster, but

petrol 50-70=8.3sec.
diesel 50-70=7.6sec.

So the diesel feels strong but the petrol is actually faster, as power increases with revs in petrol and alows longer time spent in gears. But diesel is faster than petrol car in everyday driving. Also available in almost all gears as max power is down at 1900rpm and not 5600rpm.


God i'm getting sadder by the day.
