Hi guys, many many years since last time i posted here but still alive !! :-)))
I have a fast question being in the process to change my stock clutch.
I have a K24/18G setup with injectors tuned at 1.32 bar.
Is there anyone who can tell me, approximately, which is the the max torque in NM with this boost ?
I'm installing a 890 NM sachs new clutch that should be ok ... just want some opinions !
Thanks

 

It's been a while, but I would think you'd be good.

 

it schould be around 900Nm at 4250 rpm (if you tuned at 1.3 bar at this rpm) Mine hold 900Nm with the sachs clutch perfekt

 

Ok, as i thought ... i'm close to its limit but it should hold without problems !
I'm really surprised about performance of the stock clutch holding that amount of torque for so many miles.
Thinking about a 1100 NM clutch but the feeling is that i would lose the daily drivability that is something i wouldn't like.
Thanks for inputs !

 

a 900NM Sachs Clutch is perfekt like stock on a gt2 / a 1100Nm clutch maybe another story

 

I had problems with the sachs 890nm set-up with K24/18G's and full supporting mods. Went through 3 completely new clutch set-ups with Sachs motorsport GT2 style rigid disc, 890nm pressure plate, DMFW. Each started slipping in less than 1 year. Finally went with Protomotive twin disc. No slipping, locks in/clamps very solidly/very well. That was my solution. It uses the 764 PP, but with two OEM sprung discs and the Sachs LWFW.

 

the 3.6 mezger with good bolt ons is able to make more then 900Nm with mor than 1.2 bar at 4000rpm / to much boost from down low is the problem, not only for the clutch/ at higher rpm you can go higher with your boost

Forgot to mention, I run about 1.32 bar, in the summer. The car shows higher boost in cooler weather...

 

John how do you like the protomotive twin disk set up, did you order whole thing from Todd or did the upgrade?

 

I am very happy with it - it's a little trickier to drive than a DMF set-up, thus takes a little getting used to. It is similar to a LWF clutch, as it uses a LWF. It works and performs extremely well, such a solid locked in feel when it engages and confidence inspiring that I will not have any slippage. I am used to it now and really enjoy it.

 

I just found an old dyno - max torque in my case was 610 ft/lb. or 827nm with K24/18G's at 1.27 bar. I have since tweaked the tune to 1.32 bar. IMO, it's borderline at 890nm. I had to go to a twin disc setup to hold the power in cooler weather. The car would overpower a new Sachs motorsport GT2 disc with 764PP. I even tried a tweaked 764PP by Clutchmasters that was supposed to add significant clamping force to an OEM 764. Still didn't hold.

 

Hey John.
How are you? Hope all is well!!!

 

Hi Mike,

Everything is great here, I hope everything is good with you as well!

I see you went to a 997 Turbo - congrats!

 

Hey John, thank you very much for the informations !
I think that we have a very similar setup.
I'll take in strong consideration what you have suggested.
How many HP is supposed to produce, at 1.32 bar, at the engine ?

 

My dyno guy estimated 690 flywheel HP on race fuel and about 650 flywheel HP on 93 octane.
