20/22 pounds of boost??? Holy sh!t ...

How quick will that burn out the engine/turbo?? I thought increasing to 12-14 psi was really pushing it, but there you go, I am an idiot as it turns out as I didn't even realise you could push it that high (in non-comp style vehicles that aren't heavily modified to cope that is).

Sounds like a dead set beast ... and let's face it, people in convertibles deserve all they get ...
