In case you are wondering, the answer is 5psi at 4500rpm at around 40% throttle.

5psi at 4500rpm at 40% throttle is the point at which my stock NT clutch starts slipping. This is part throttle by the way. If I just mash the throttle, I hit 10.5psi and the clutch just say "Fu*k it".

So, there is the answer. It may be a case by case basis, but in my case, 5psi at 4500rpm at 40% throttle is when my NT clutch gives up the fight and just slips. I will say though that it's still a hell of a lot faster than when my NT was still an NT.

I used a logger to get my TPS position which is how I know it's 40% throttle.

/starts saving for ACT2600.

Oh this was in 3rd gear.

it was only a matter of time. mine eventually got so hot i had a few heat stress cracks around the springs on the friction disc.

for your clutch needs check out www.clutchcityonline.com by far the cheapest place online to pick up act clutches. includes all part numbers and act's specs on torque holding capacity. i've never ordered from them, but they look good for whatever that's worth

No money right now. So I'm going to just have to baby it.

one easy option, disconnect the wastegate actuator arm from the wastegate itself. that way you won't build any boost. it'll be slightly slower than it was nt since you'll have more backpressure due to the turbo, but it'll be a guaranteed way to avoid damaging the clutch anymore and possibly shattering it or something.
