CFM= How much boost?

[dfiore]

What is the formula that described CFM, circumference and Lbs of boost?

[Willie Williford]

I don't know of a formula that has the specific things you are asking for.
CFM, p-Dia.,and PSI.
What are you trying to figure out.?

Possibly what turbo to use on the Insight?

There is none made especially for the Insight.

either that or if I could find a DC motor. I know some of these "electric turbos" are bunk, but there's chance that I could wire the right thing up. I experimented with a 200mph leaf blower, but I kept popping the breaker on the inverter from the surge current.
