FYI, FVD has a big sale on clutch kits and individual FW/discs/plates for 5 more days. They are mostly Sachs parts.

The NM ratings seem underated. Any thoughts? Looking to support 700hp/torque and I do not want a LWFW.

 

Why? Just curious as it seems like a no-brainer on a high HP car.

 

That's a valid question. The answer is noise. It's a daily driven street car and my family often rides in it with me (wife and 2-1/2 year old daughter). Sometimes my wife drives it. I actually prefer for her to take it when shopping...there is a whole lot less room than her Odyssey minivan and thus her spending is limited.

 

roadsterdoc,

I felt the same way. I did the LWF on my 993TT and had it removed, strictly due to the unpleasant noise. The car ran fantastic with it and I enjoyed the quick revs, etc., but I just couldn't embrace the sound.

When it came time for a new clutch on my 996TT, I spoke to several tuners about my goals, preferences, etc. My main goal was to 1/4 mile as quick as possible and if the LWF was going to make it happen, I would have done it. The funny thing is...Todd Z at EVO, Todd K at Protomotive, Sam at Speed Gallery and Stephen at Imagine Auto all said the car would 1/4 mile faster with some mass on the flywheel.

I ended up going with Todd K's suggestion of the Sachs Motorsport 999 pressure plate, OEM GT2 disk (which is slightly grippier than the OEM turbo disk) and stock flywheel. Protomotive has successfully used this combination on 700+ HP cars.

I also converted to the non-assisted GT2/GT3 clutch set-up and removed the accumulator and some lines....saving a little weight and eliminating the vague feel of the over assisted OEM turbo clutch.

Here are a few pictures:

Awesome info John. How does the clutch pedal feel after these mods? My only complaint about this car from day one is the lousy clutch pedal feel: vague feedback and short action at the top of the pedal stroke.

edit: that disk is unsprung! Is it abrupt on the release?

 

roadster,

I don't have the car back yet from the conversion, so I can't comment positively. I am going from what some of the tuners have said...and having drivin a 996 C2, which does not have an assisted clutch (it has better feel than the turbo). The difference being the turbo has a heavier PP and then the Sachs "999" Motorsport PP is even heavier, so the big question is - how much effort will it take to work my new clutch? The general consensus is obviously more force, but nothing wild.

That is a stock GT2 disk - same as the stock turbo disk, only it has a "slightly" different compound make-up. It's basically the same thing as a stock turbo disk...which is not sprung.

 

GT2 used the same disc and setup. It should be about the same.

 

That is exactly what I just put in...it is excellent with the dual mass flywheel. I just hope it lasts.

My disc was also unsprung.

 

I had the sachs clutch with light weight flywheel from FVD... very good stuff.

 

Ben,

With the power you are making I hope you used a dual friction disc. The PP might hold, but the disc shown above....hmmm

 

That is such a great idea Ben...now get your freaking car already and report back!

Ben, did you also delete the clutch accumulator and use the GT2/3 slave?

 

Which ones, Mark? They have several. Also I'm trying to decide if those prices are unheard of...you know, debating if should I jump on them now, or pass and keep collecting more info about the different options.

 

Roadsterdoc,

The pricing for the 1200 kit is not bad, in all honesty it is not that much cheaper than some of us sell similar setups for. DO you know if that is a 3082 PP?

 

Stephen,

We'll know for sure how the disk holds up later this year, as I don't intend to baby it

 

What was the cost (P&L) to go to an unassisted setup? I know it can be done, but it wasn't really on my radar until just now..
