I remember in my fluid dynamics class, id always bug the professor and tell him how much pressure flows. Pressure does not flow. Pressure is the result of restriction to flow. :icon_bigg


Hooray,

someone gets it! lol

Please correct me if I am wrong but ultimately would not the smaller compressor choke the system once it has reached its peak mass flow?
Larger than ambient pressures at the inlet of the compressor would allow for larger manifold pressures with lower PR but overall mass flow cannot exceed that of the smaller compressor.
I've always thought that myself

Smaller turbo practicly stops spinning once the big turbo passes the pressure the first wastegate is set up (wastegate completly opens). Smaller turbo becomes just an intercooler pipe.

Kean and Marc at Boost Logic here in Austin built that coumpound turbo setup. It accelerates like a V8, very little lag and builds constant torque throughout the powerband. Marc is a good friend of mine, he was their in house fabricator.

This is another one that they built. This is Marc's personal toy, he built this thing out of junkyard parts and last time I saw him he was running mid 10's with slicks, without the nitrous, he was shooting for 9 second passes with it. Keep in mind, this is a junkyard 2JZ-GE. He fabricated everything after hours from everyone's scrap parts, and sure it also helps to have accessibility to Boost Logics shop. Pretty awesome, the ultimate sleeper, that shocked Vipers, Vettes, etc here on the streets!
