I'm currently getting 300rwkw from a GT30 and a 45mm wastgate at 17psi, so when my forgies are in and I want to push for 400rwkw you think the wastegate is oversized?
Aidwin, Nothing much we hope, just the clutch fork isn't fully disengaging, which means the carrier may just need shortening, Ant will fix it for you, he had to do Jeff's the other day too.
