Stage 1 which is the non intercooled setup with headers is said to make around 340 at the crank, with an intercooler and .7bar 400 is said to be achieved. It does sound like a hell of a lot but as I said this is what merv started out with and he did get numbers on the dyno to back up protomotive's claims. I'll ask him for more info, his thread is somewhere on this forum.

I have head from many people that the carrera engine does respond surprisingly well to boost and over here, back in the day, people where importing wide bodied carreras and turboing them to race over buying 930s as they had efi and a 5 speed. This is also meaned in the 101 projects book.
