so from all the pics i have seen on the web it looks like the compressed air from the big turbo is piped into the inlet of the little turbo. Wouldnt the large air flow from the big turbo cause the smaller primary turbo to over spin? Or am i being a dumb *** and not realizing that the big turbo is the one attached to the manifold and the boost form the little turbo is charging the larger one?

thanks for the help

 

little one spinnin the bigen.

 

You need to think of the turbos in their two stages
Turbine section of the top (small) turbo drops down to the bottom (large) turbo then out to the exhaust.
Compressor section of the bottom turbo sucks in a large volume of air and packs it down to send it up to the top turbo witch in turn really packs it into the CAC.
Where the fun begins is when the wastegate on the top opens and really spins the bottom

 

Check out this thread it's all the same things just on a Twelve valve I enven put in some CR Twins and some others.
