ACT Clutch and High RPM lockout issues ??
Anyone who have an ACT clutch with high rpm lockout fix their problem yet? I tried adjust my clutch rod and it seemed to help but the problem still exist. This SUCKS!!! There's about 1.5 thread left on the nut side. How's this compare to everyone else?
Anyone know if I can adjust it to .5 thread or less? When will I know adjustment is too much?
Thanks.

After I adjusted mine to the point that there were 2 threads remaining, it no longer locked me out. After 4 months or so, it still has not locked me out, and I haven't missed a single shift in 40 passes down the drag strip. I recently removed the clutch restrictor and installed a SS clutch line, which lowered my pedal engagement slightly, but I still have not been locked out. Crossing my fingers hoping it stays this way for a long time...
I just adjusted the rod to have about 1 thread left. I don't know if it's me, my transmission is mess up, or what. How do you guys shift with the ACT clutch?
I can't quick shift at all and this is where I'm losing the times . It's either miss shift or it won't go in cleanly! My best time 1/4 time was 12.19. Best trap was 114 and best 60ft time was 1.692. With a good launch and shifting I'm sure this thing can hit 11. Mods are BR S4 with alky kit at 25 psi with pump gas. Ran it like I was driving daily with no weight removal, 30 psi all around on ASX tires, etc.

I am sorry you are still having troubles. If it is happening in all gears then it is more likely to be clutch system related. If it is only happening in one or two gears only then I would by suspicious of the transmission. Does it only happen at high rpms or all the time? Keep me posted. I would like to know what is going on.

Thanks for chiming in. It only happens at high rpm during shifting. Under normal driving it shifts fine. The pedal engagement seems to become higher and higher now
I try to shift early going from first to second so it seems to help but second to third is a bit**. This is where I shift at 7300-7500. If I slow down the shift it seems to help but I can't quick shift (not powershift) . I'm going to try removing the restrictor to see if it helps. It's not going to happen until Spring though
It could be the my shifting, the transmission, clutch, or synchros but not sure. Either I get the POS tranny rebuilt or maybe trade this sucker in for a minivan
Either case it's $$$$$$$$$ out

The dynamics at high rpm are a bit different. I am sure you read the page I put together on the subject of lockout. At high rpm the clutch requires more air gap (higher adjustment) than at lower rpms. Also the syncros will not work as good, and the type or viscosity of the oil has more affect.
The restrictor should not matter at all, but it won't hurt either.
its interesting that u say the restrictor doesnt matter, but so many swear by it when they go for installs. i thought the restrictor slowed fluid from the pedal to the tranny so removing it would help!

I have been fighting the lock out big time.
My mods:
ACT Clutch
Fidonza Alu fly wheel
Royal Purple 85-90 gear oil. (may be 80-90)
SS clutch line
Restrictor removed
Clutch rod - not adjusted
Clutch pedal - not adjusted
Brass shifter bushings (engine and inside)
Short throw shifter
I always get locked out above 6K rpm. I am going to try and adjust the rod on the tranny. I will let you guys know what I find. I cant run faster than 12.7 / 115 due to the loss of momentum during my looooooong shifts.
I H A T E T H E L O C K - O U T ! ! !
I hope this helps. I was about to get a Exedy twin to help fix it too. This might keep me going with ACT.
