What power are people running on a standard OE Clutch before it slips?

I'm running at 350 at the moment, and haven't had a problem. But I'm going for more soon and hope it will last with more power......?

 

i would say you were at your limit regarding clutch the exedy organic clutches are good for 400 bhp+

 

Thats a shame Was hoping it would go for more....

 

Oh, it's on a 2003 STI as well by the way

 

I'm on 347/343 with the standard clutch (05 WRX not STi) did a launch last night and the wheels were spinning all the way in first gear with no slip or smell!

Not sure but the STi clutch may be different to the stock WRX one, worth checking out

 

Iain! Yes, the STi that have 6-gear boxes have bigger diameter clutches.

 

its on a classic but i ran 320bhp 336lb on a std p1 clutch and give it its due it ran for 3 years before starting to slip but the general is th3 350lb mark i think so i woul dsay give it a go and when it slips get it changed oh but hope that is not on the day of the mapping

 

cheers Adam, so the question I was trying to ask (badly .... lol) was whether the stock STi clutch is designed to take a bit more power than the stock WRX clutch

 

Yes.

 

thanks Bob we got there in the end

 

Sure! But you will need the clutch from a 5-speed STi, not a newage 6gear one.

 

Will my OE last at 400 then for a while? Maybe 420bhp?


Thanks

 

if you treat it kindly then yes it will for a bit

 

Is that 350bhp or 350lbs torque? I believe it's the torque figure you may want to look into.

 

I'm not sure what my torque is to be honest.

 

Hi Chris, After fitting a bigger turbo, before it was even mapped, my std clutch started slipping, was running around 340 bhp with no symptoms for nearly two years.

Now it's mapped I fear it would have shredded it in seconds, no launches, or crazy drive it like you stole stuff either.

HTH

dunx

P.S. I regarded it as an essential up-grade, not an option.

 

Damn I've ran out of money now really......

Hope it last for my holiday when i'm taking my car on a looooong trip.

 

i ran mine at 383bhp for over a year on the standered clutch,did countless full bore launches on the strip and it never slipped once.only changed it as i was having a lot more mods done to the car so i thought it was wise while it was in to have i changed.

 

hi mate i got 2003 sti and ran on standard clutch at 347/340 all day long now i'm 405/385 and it lasted 3 months, have fitted the exedy organic and its holding up very well considering the spirited driving...lol

 

Mine is sat in the garage still, it wasn't worn out.... just couldn't hold the torque ! And I would have said it had led an easy life with little abuse.

dunx

P.S. You don't want to find yours giving up on a mountain pass in Italy do you ?

 

hehe, no that would be bad!

Mine is at 350 now, and hasn't once smelt or slipped or anything.

May have to think about getting it done before i do go in July

Is Bob the man to speak to?

Cheers

 

Clutches are rated in torque not bhp think these are good for about 450lbs, but it does depend on how you use it

Tony

 

My standard clutch should be ok for 450lbs you mean Tony? As I won't be hitting that when I get the remap.

What are all the types of clutches? There seems to be Single, Twin/Double and Organic. Think IF I do change I'd go for an Exedy. Which would suit me best out of the options?


Thanks a lot
