Everytime I start to let out of the clutch peddle it makes an aweful sound, and does it for about a 1000rpms. The only way around it is to just drop the clutch. It seems it has gotten worse over time. I do have an exedy twin.

Also my gears feel really notchy.

And finally one tuning on the aem. we get knock about 7000 rpms no matter what the boost and what type of gas were running. which we were thinking may be transmission noise.

 

maybe it is the throw out bearing

 

What exactly is an "aweful sound?"

 

metal clanking together with a little bid of grinding. if that helps

 

@ 7k??? or when you let it out??? what kind of knock volts are you seeing @ 7k????
