I have been having troubles when I stage and begin to preload at 6k-7k my car starts pulling foward.The pedal is pressed all the way to the floor.I have checked thrust on the crank its good,replaced slace cyl it was leaking,tried 3 different clutch and flywheel combos,and adj the clutch rod both ways and no change.Currently have a clutch masters s5 4 puck unsprung w/ exedy flywheel.Also the pucks on the first 2 clutches were ate up.WTF I'm tryin to get fixed so I can go get my race gas tune.

General info:
2000 si
gsr block w/ ls crank
si tranny

 

may sound a little simple but theck the clutch line (bleeding it a few more times, fork and clutch MC... if these are all checked i'd think perhaps the pilot bearing?

 

New pilot bearing and clutch fork looks good.Im going to try a master cyl just for s&g Thanks for the advice

 

make sure you have the correct free play. if it isnt fully disengaging, it will lurch forward.

 

ive checked it and rechecked it going to put on a mc tomorrow and see how it goes.

 

if it's a built motor it might not be balanced right and thats causing the kreep at the light

 

I had the rotating assy balanced before installed and this problem is a recent thing it didnt have this problem after the tune.In fact i didnt get this problem until the first s5 clutchmasters shated on me.Since then its been one thing after another

 

Thanks guys for the help but I found out what the culprit was I had a broke crankshaft on the main closest to the flywheel.
