unspankable

Hello all,
this is my first build and I am having a few issues I was hoping I could get some help with.

First off- I have a new Howe Racing pull slave cylinder to clear my down pipe as seen here-

Fluid I am using Pentosin Dot 4 LV here-

New Nissin Clutch Master cylinder
New Competition Clutch Ironman and pressure plate


When I shift at high rpm with the turbo spooled/in boost, the clutch pedal will lose all pressure and just stay on the floor when I press it. The clutch stays engaged, i.e. I can accelerate even with the clutch pedal on the floor.
I can pull it up with my foot and as I slow down/lower rpm, if I pump it with my foot pressure returns. This does not happen when I drive slowly/ in vacuum.
I see no leaks in the system when I look, and am not losing hydraulic fluid that I can see.

-Am I boiling my fluid?
-Is the pressure plate pooched?
-Any other suggestions?

Thank you very much for any input, this is frustrating to say the least.

Did you bleed the system properly or did you just install the parts throw some fluid in and go?

I'm pretty sure he did look at that part list buddy.

Drag section will probably be more help

Thanks Ill post there.
Definitely bled the **** out of it both gravity and using a vacuum bleeder, no dice.

Bad pull slave.
Switched out for Prelude slave and problem fixed.
