Twin Turbo on 2.5

Hello,

Finally a few pictures from my Twin Turbo install.

The Supercharger removal and twin turbo install was handled by TurboWerx shop in Austin.

I also dynoed the car this weekend, as of now (it still needs another test and tune day) it is producing 50 - 60 horsepower more than stock all across the rpm. We think we can get another 20-30hp out of it. In comparison to the sc the turbos are producing 25 to 30 hp over the sc early in the rpms, I think that is because the turbos spool up so much faster than the supercharger did.

As of now I am getting full boost at 2800 rpm and carry the full boost all the way to red line.

Because of the heat wrap on the wires the dyno shop was unable to get a RPM read so I only have horsepower numbers. The next set of dynoes will have rpm numbers so next time I will have tourqe numbers. The Dyno Tech who has dynoed the car 4 other times said the tourqe was noticeably stronger.

I posted a video of the dyno pull from this weekend. The link is at

Please ask any questions,
Gary

Growing up the car magazines said how amazing Porsches are. Was I brainwashed? Somehow...I doubt it.
