more like 23psi. I like the idea of a little turbo and cross over, but I am beginning to c your point about the bigger turbo. Just means more money and then will definitely have to replace my standard fuel pump. As for my ZF going bang. It was fine at the track, but I did snap my input shaft when Nizpro was doing a ZF tune on the gearbox. Still reckon I can get a high 10 with standard turbo if conditions are right and launch is perfect.
