I had a stage 3, 6 puk clutch in a tdo5 wrx and it used to spin the clutch in 4th on boost.
Be aware of if its slipping.
Also my mate spun his clutch in top gear in a xr8. (going too fast) he didn't notice it was slipping. when it exploded, it wrote of his car. he still has his own feet, but it was touch and go for a while.
