C900 Clutch Upgrade Options


clutch_compare.jpg

I was having some trouble with my clutch, so I decided it was time to upgrade! I guess I was trying to put a little to much power through it!

My mechanic recommended me to get a 9000 clutch, because it has a bigger surface area. In this picture you can really see the differences between the stock 900 Turbo clutch and the 9000 turbo clutch.

The springs are bigger and the disc has a bigger diameter. You also have to combine this with the 9000 pressure plate and a 1990-1993 C900 Turbo (1994 CV) flywheel. Do not get a 2.1 flywheel, these will not work! The reason you need the new flywheel is because the 9000 pressure plate has smaller holes for the metal pegs that support the pressure plate and the bolts that hold the pressure plate onto the flywheel are in different places. The 3 metal pegs sit in the flywheel to center the pressure plate.

The 1990-1993 900 Turbo (1994 CV) flywheel is the same as the 2.3 9000 turbo flywheel, except the timing marks are different. You could use the 9000 flywheel and get the timing marks reground.
You will want to buy the 1991-1993 9000 Turbo clutch to fit the flywheel. SAAB Changed the input shaft in 1994 so those won't work. You will also want to have the flywheel resurfaced since this new clutch disc is 0.5" bigger.


After heavily modifying the SAAB, I have had NO problems with this setup. I believe you will be good to around 270 HP with this setup.

If you are beyond this horsepower, your options vary widely.
Some people have purchased a SACHS high performance pressure plate and others have gone with different, grippier disc materials.

The utimate solution is a dual disc clutch from Scanwest. It'll cost you about $2000, but I guess it's the best you will ever get for a C900!
