Draw through slant six turbo setup

I am going to take higher quality pictures of it today and upload them. My three and a half year old blackberry phone has seen better days, and the picture lens is scratched to hell. Sorry for the fuzzy pics.

The last picture shows me putzing around at 5lbs of boost part throttle, I have seen it build nearly 9 pounds of boost, but let off before getting to wild as I want to do more work with timing. The vacuum/boost gauge is plumbed into the intake manifold on the rearmost intake runner.

Currently running 10° initial with about 16° mechanical, which i want to get down to 8° for 18° total. I will be hooking up the vacuum advance straight to the manifold to get more advance under vacuum that will be gone in boost.
