NEW HPF BMW 135i/335i Stage 1 FERAMIC (750rwhp) Clutch

HPF Chris · 10-04-2011, 06:33 PM

I've been driving on our Feramic clutches for around 10 years now in my Supra, Viper, M3 and now we've built the same clutch material into the 135i/335i and upped the pressure plate clamp load from 1800 lbs to 2500 lbs for our stage 1. This clutch is simply amazing. Not only does it handle up to 750rwhp/600ft-lbs but it drives like it did from the factory with a minimal 25% pedal effort increase. We installed our first one in Tim's 135i today. The engagement was a little too close to the floor. Our first production run will have a slightly thinner clutch disk so the clutch will engage at the same pedal height as the factory clutch. But you can get a really good idea about how the clutch drives with three different people taking the 135i out for the first time.

Here is the Go Pro Video....

How about a 750whp n54 turbo kit/upgrade?

Does changing out the clutch/flywheel combo get rid of this shift delay problem? I have spoken with others and I know it's not just my car. I bought a modified CDV (with valve removed) but I still get shift delays... especialy when going from 3rd gear to 4th gear it is like I don't fully engage power for a 1/2 second or something. Very annoying at any track or drag strip. I don't think the clutch is slipping because I never smell anything, but I guess that is possible. It has always been 3x worse though going from 3rd to 4th in my car; stock tune, SSTT tune, Cobb tune - doesn't matter. I want to blame the dual-mass flywheel or something lol!~

Are you referring to shift bog? Cause that is normally tune related although this car can do it stock. Regardless it doesnt have anything to do with hardware on the car. It's either throttle closure or timing drop out post shift.

I guess, like you are drag racing and you make a quick shift from 3rd to 4th gear and the car just doesn't accelerate for like 1/2 a second (feels like forever lol). Since I have tried 3 tunes, I was hoping it was just clutch related or something

i felt mine do this the other day but it only does it like dtc is kicking in or something. because it only happens if its in a lower traction situation.... yet i have dtc completely off. running v5 on 7-29 map and you can here the tires slipping through first, fast shift into second, what would be a hard chirp or break loose into second and it feels like i just speed shifted a damn honda civic for a second for second because it COMPLETELY cuts power but doesnt show a dtc light or anything since it is already fully disengaged. half second later power is back and it starts pulling like a beast again.

I want to see how it engages on a clutch dump, just to see a nice burnout.

How much?

onesuperboi · 10-04-2011, 10:44 PM

Very nice. But unfortunately while watching the video, I was thinking about the HPF's claim that the exhaust has no drone...

Rotorocious · 10-04-2011, 11:05 PM

Cost!?
My clutch slipped tonight

edit: previously said a little over 1k

You sound exactly like Shiv here... lol

TT3 iN NyC · 10-05-2011, 09:11 AM

Chris, what do you have in store for us 6AT guys. I don't think our 6AT trannies can handle 600lbs of TQ. What steps is HpF going to take for us?

Thanks.

FazerBoy · 10-05-2011, 09:19 AM

How much is this going to cost?

probably an arm and a leg

looks really good though.

G.I.Joe · 10-05-2011, 10:13 AM

Looking good. I need a new clutch soon anyway

Zasquatch · 10-05-2011, 10:21 AM

In the other thread you mentioned this would cost just over $1,000.00...... Why? Honestly, what makes this clutch cost over twice as much as an ACT clutch? With some searching one can find an ACT street for a little over $400. I'm genuinly curious.
