Would it be possible to run 8 psi of boost on a 10:3 CR motor? Street car.

Even with race gas you'd still be pushing it. Drop it down to 9-9.5:1 at least.

with the right tune and right enternals you could but it might get kinda costly

if you run an intercooler you would proably be ok, just need to keep the egts low as possible. 8psi of peak boost is not to bad, If it was my motor I would either bring down the boost or bring down the compression.

I'd have to say no. 10.3 is a high for a NA street engine let alone a boosted one.

I would have to agree. That's pretty steep compression.
I've swapped heads to larger chambers, and lowered compression in the past with success to allow for small amounts of boost.
