chicagobob,
SAE has standards you need to adhere to. The standards are for physical testing.

Crysta1c1ear,
you need to be a little bit careful here, increasing the inlet pressure increases the inlet density. Decreasing the inlet temperature increases the inlet density. rho = P/rT
The compressible flow equation mdot = C*A2*P1*SQRT[(gc/RT1)*k*(2/(k+1))^{(k+1)/(k-1)}]
mdot is directly...
Typically, the best you can do is a well designed venturi with a smooth surface finish, rounded inlet, and a 7-10 degree diffuser. The diffuser would be ideal if it opened to the full diameter of the turbo inlet, but typically the distance from compressor wheel rule makes this a bit difficult...
