Clutch getting stuck at high RPM shifts.
I just got done installing a Spec clutch, Spec PP, F1 flywheel and i replaced a gear stack in my transmission. The car drives fine until i get into high rpm's and try to shift gears. My clutch peddle gets stuck near the firewall for about 1 second after i let off the peddle when i am shifting at a high RPM (5,000+). I have already tried loosening the clutch cable and it didn't help. I also checked to see if any wires anything else could be stopping the clutch lever on transmission or peddle and everything seems to check out ok. Could this be from my PP being over tightened?

I been having this problem also with my brothers b13 ve. We thew in a new cable and greased the hell out of it and tightened it up a bit. Someone mentions that maybe the spring in the tranny that springs back the arm could be acting up. Idk so far its hasnt given us a problem but it was annoying before when it would stick.

D-unit and I have the same flywheel but two different clutches and both of our trannies have been rebuilt but not by the same person..

We both have the same exact clutch pedal sticking problem.

What could it be?

The only thing in our setups that are the same are whe both have VEs, Same exact flywheel both brand new and same tranny.

We are also both running the same GL-4 gear oil.

It is possible that when the engine speed is greater than 6000 RPM and the clutch pedal is depressed, centrifugal loads on the clutch diaphragm spring may be greater than the clutch return load from the diaphragm spring. This force created by RPM would be directionally opposite to the clutch bearing force, causing a near net zero or less than zero return force. As a consequence, the clutch pedal may be stuck at the bottom of travel at the floor. Once the engine speed reduces to less than 6000 RPM, spring return load dominates and the clutch pedal returns to normal function

My se-r used to do that changed the clutch cable and it still did it went to autozone in the help aisle and bought a sping put one end on the clutch arm on the tranny where the clutch cable attaches and put the other end on the radiator support and problem solved I paid 3.99 for the spring so whenever I buy other SE-R's (currently on my seventh) this is the first mod I do lol

yah thats the ghetto plan but i like to fix things right if possible

also let me add that my clutch peddle feels slightly softer at high rpms.

Wow this makes complete sense!

I'm pretty sure you solved it.

Sooo... We need to come up with stiffer load springs for the clutch arm on the inside of the tranny correct?



Note: Temporary fix will be to put a spring on the external part of the arm to aid in the return.

also the step on the flywheel could be the wrong hieght?

True very true but I needed a quick fix before I went to the track and it worked so well I got lazy and never looked back lol. Also it had a fresh clutch cable and I was running an ACT clutch and pressure plate combo.
