Reading about and watching the videos on the 928 Turbo guys, they have really got their stuff together. The are running the boost pressures based on the cylinder pressures. The run about 14 psi until the cams and cylinder pressures start dropping off then raise the boost up to 17 psi. And that's with a stock 10.4 compression ratio. They are building their twin turbo to run on pump gas and be super reliable. They have been building them for 8 years and none have cratered yet.

They had a whole video on just how they fabbed the instercoolers into the bumper covers to look normal.

To bad they guys want $25K for the motor build up and install.

They are getting a bit more horsepower than the superchargers or strokers though.
