Is anyone making 400whp on the stock clutch if u are. How does it hold all the hp and tq

[YMB_M3]

I am,
with 445lbs of tq and it doesnt slip
26k miles on the car if that makes a difference

[Bme30]

I was for a little bit but started getting slip around 35k. My car was tuned from 18k miles. If that means anything.

[Quebequer]

Still no slip here on stock clutch, car is XI fbo w/meth, 51k miles.

I'm still on the original clutch as far as I know...bought the car in January with about 55k miles on it and now have around 65k. My first trip to the dragstrip in April was fine, it would spin the tires (AWD). My second trip to the dragstrip a few weeks ago making quite a bit more power (similar to the E30 race map, plus a DCI) and it didn't hook up on a 5000rpm full throttle launch...slipped through first until I let off. Still fine for normal driving but I need something better/newer for drag racing. If I were RWD there wouldn't be a problem yet, I'd just be spinning tires.

Alright because I wanna go jb4 Dci dp and e85 but I don't have money for a clutch right now it's gas 19k on it not really beaten on to bad

I am at 71k miles FBO+Meth on the stock clutch. I don't launch the car though so that's probably why it is still holding up.

I think I should be fine I only do rolls no digs

Mine is fine on pump gas, but is just starting to slip on my E85 tune which exceeds 450wtq.

Mine did great FBO + meth before e85. Since I've been over 450tq it's started slipping. It was holding like a champ for a long time though!

[psmitty95]

Anyone know if theres anyway I could check wether or not my clutch is OEM without actually dropping the transmission? Only reason I ask is i bought the car with 47k miles on it and for some reason I feel like its not a stock clutch. I know BMW clutch pedals are supposed to be stiff but mine seems a lot stiffer than any other stick car i've driven. It also has a pretty harsh engagement and has taken a ton of really shitty launches by me when I was learning how to launch. What I mean by that is my first few launches I let it out way to slowly so I was burning a lot of clutch but yet somehow I still don't slip if I floor it in 6th gear

^ditto.

[Ferruccio]

I guess I'll contribute!

My clutch was fine up to 46000 miles, now it's slipping quite a bit with the E85 kit So much torque!

[blackshan]

I'm fbo with meth and close to 60k miles with stock clutch! For now!

OP, with e85 you might make too much tq for the clutch depending on your tune. Mine held but when tuning on the dyno it started slipping when I went past 47x wtq (Mustang dyno).

You can take off the slave cylinder and look for aftermarket PP. the ACT one is bright yellow. You likely have a stock clutch. The stock pedal is soft.

[rdeterman]

what that kind of power you will be fine on the street.. once you get on the drag strip with sticky tires your gonna be on borrowed time

Idk how to take off the slave cylinder but my pedal is definitely not soft... A lot stiffer than any other clutch i've ever driven. That includes my friends S4, Jetta, and STi.
