Recently I decided to put my 1990 Callaway Twin Turbo on my DynoJet to free up the McLeod Street Twin that had "stuck" itself to the flywheel.
After a few boost runs with the clutch pedal depressed, it finally broke free. Sure beats the heck out of pulling the clutch out of the car!
At any rate, since the car was strapped down I decided to make a few runs on the car.
The first set of runs was at appx. 17.5 psi of boost. The best run was 595.51 rwhp / 673.49 rwtq. I then turned the screws on the wastegate one additional turn and the result was appx. 20 psi of boost. The best run was 654.84 rwhp / 727.28 rwtq. Finally, I turned the screws on the wastegates one more additional turn and the result was appx. 24 psi of boost! That run was 713.84 rwhp / 746.18 rwtq.
