HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Car lift installed, now the real work will begin.

Post  acorad on Tue Jan 31, 2012 12:54 pm

Several months ago I happened on a used car lift for sale and decided to pick it up. Yesterday I finally finished the install and today I lifted my car for the first time!

Now the real work will begin.

Must do:
1. Swap out lightweight Findanza fly wheel and spec kevlar clutch for a more street-friendly combination, balance FW and PP - any suggestions on good street combinations?
2. Rebuild control arms - probably brass bushing kit from Pelican
3. Rebuild front struts - DSide blew out, probably Koni hacksaw
4. Replace leaking RH radiator - probably 951 w/dual fan
5. LS6 PCV/valley pan to reduce oil consumption
6. Install Xschop short shifter
7. Install 0.68 5th gear
8. Locate exhaust leak (sounds like driver's side engine somewhere)

Probables:
1. TT bearings
2. Modify trans mount, Xschop or liquid polyurethane - I have a stabilizer shaft from trans to frame which seems to work well, but I wonder if the Xschop/liquid poly mod would be quieter?
3. Insulate trans tunnel - gets hot here in SoCal
4. Power brakes - several different options here

fwiw, here's that trans stabilizer shaft I talked about. As it's metal-on-metal, I figure it's transmitting a lot of noise to the chassis.[You must be registered and logged in to see this image.]

I could have used that on my clutch repair. I've heard from two different people that the trans poly-fill method broke loose under hard abuse.

Xschop, what clutch/FW/PP are you running now?

Fidanza FW, Centerforce PP, and 11" Clutch disc I had made. Switched to a 13/16" Wilwood Clutch MC

Yes, I recently broke my stock trans mount that was filled with window weld while at Sebring (rough track). I had a stabilizer bar for the trans in my last car but had not put one on the new car. Ordered Xchops trans mount and will install this weekend. Will also add a bar for extra measure.

Congrats on the lift, it makes working on these cars so much more enjoyable.

Soooo jealous! I want a lift so badly. I bought my current house because it has a nice 3 car garage with a very high ceiling so a lift will fit nicely.

For a clutch I'm really happy with my Spec Stage 2 clutch and lightweight flywheel.

Where'd you source the 0.68 fifth gear from and how much was it? I want one of those...

doc, the 0.68 5th was from a mid '80's Audi diesel. I've posted about this before, it's from my own research - no one else has done it, afaik - so we'll see if it fits ok!

Like you I also have a light weight Fidanza FW and Spec (2, I think) kevlar clutch.

The car is my preferred DD and the clutch chatters a lot and really bugs me at stoplights and in stop and go traffic. I drop my younger son at school a couple times/week, and waiting in line, stop and go clutching up that steep hill to the school, engine/trans/etc chattering like a mofo, is a royal pita. Mostly at stoplights I can rev it up a bit to lessen the chatter, but it does chatter at least a little almost every time.

Do you get a lot of clutch chatter in daily driving?

And for a DD I think I'd rather have the OEM 28 lb (or whatever) FW to make things smoother all around.

I guess I'm really looking for a DD clutch/FW combo.

Open to suggestions if anyone has any, although most here are probably looking for a more performance-oriented setup than I am...

lemming and Xschop, thanks for the info on the window weld trans mount mod, I'll look into it some more. I guess I'll pull the stabilizer off for a day or two to see how much gear noise from it there really is.

I get ZERO chatter with the normal disc compound. I thought I was getting a slight noise from the poly mount, but after installing the new custom TT bearing it went away and is quiet ( I still hear the tires squeel every day LOL)

Xschop, yeah, I think the chattering is from the kevlar, normal disk compound sounds good to me...

Am I the only one running the Spec Stage III? Note, this is not a good DD clutch, but works great on the track.

My Spec stage 2 is an organic clutch, I don't think there's any kevlar in it. It doesn't chatter at all and I have no issues with engagement. It does have a heavier clutch pedal vs stock, although putting the clutch assist spring back in helped a lot.

I don't have the fidanza flywheel, I have the Spec one, that might make a difference for you too.

Let me know about the 0.68 gear and how it works out, I really need to lower the revs on my car for better highway cruising and mpg. I wish we could add a 6th gear and drop the revs 1000 like the corvettes have...

doc, are you sure about no Kevlar? From the Spec website:

"Stage 2

Types of Driving:
Street, Drag, Pulling, Autocross
Features segmented or full faced pure Kevlar disc with steel backing. This lining features excellent drivability like the stage 1, but offers slightly longer life and higher torque capacity. The hub is double sprung with spring cover relieves for flexibility and heat treated components for strength and durability. Best for street, drag, pulling and autocross.

•High clamp pressure plate
•Pure Kevlar friction material
•High torque sprung hub and disc assembly
•Bearing and tool kit"

The reason I ask is because if you do have the same (kevlar) clutch as me but have no chatter, I wonder if there's something wrong with my install.

Oh yea, mine also has a heavy duty PP, not sure what brand but I would guess Spec as it probably came with the Spec clutch.

I called SPEC, he said the Kevlar clutch should engage like buttah. He said to check that the FW is true, etc. I'd be happy to keep the clutch if it'll work well.

Looks like mine is a kevlar clutch then. I can tell you that it engages very smoothly, with no chatter or judder.

Thanks doc.

Xschop, I assume it is the RH adaptor plate. The builder used the RH kit. I almost hate to ask this but do you thik the RH adaptor plate is causing this clutch chatter problem?

Yes, that's exactly what I have.

But no, I don't know enough to see why it sucks without explanation.

Look real close at the 15mm dia. shaft insertion in relation to factory pilot bearing.....
It's sitting way off center towards driver's side....classic Grenade Hybrids LOL

Thanks Xschop.

I downloaded the pic and blew it up to see, ya, it's really off center.

If your clutch is good and you are getting uncanny vibrations at certain RPMs....the disc is oscillating/chattering upon engagement and the driveshaft is being held off center and the pilot bearing races are off kilter and wearing prematurely. The BH dowel pins to shaft centering dims are CRITICAL...... Check your adapter plate dims against these....
