Dahlback is running upwards of 35+ psi threw that
900hp monster. For a street car this is very
unrealalistic. On pump gas 21+ is pushing it w/ our
stock compression ratio. If you lowered the
compression down to 8.5:1 you could get away with
more. If you want to get a good turbo kit, Matrix
Engineering (www.matrixengineering.cc), is developing
a kit for the 3b and AAn. It will have custom GIAC
software to make big power. It will use a very nice
manifold and a big Garrett turbo. Hp goal on pump gas
is over 350.
