CFM calculation
 

Has anyone calculated the CFM and airspeed of their turbo kit? I am thinking of experimenting with several TBI injection TB's in place of the turbo technics add-on injector mount (which I most likely cannot afford). I know that GM model 220 throttle bodies (2 barrel/injector, on 305 and 350 SBCs) are dime a dozen and easily found in PNPs but only flow about 520cfm. Bigger TBs are found on 454s and pretty readily available too, flowing upwards of 650cfm (obviously better option). I would remove the butterflies, sensors, and plug everything except fuel inlet and outlet. My question is if these would create too much flow restriction.

Another consideration might be to cut out everything except the venturis and mount that within a wider pipe as to flow more air, or place it within a wider pipe so that there is enough flow around the unit (think like a hot wire MAF sensor). Just wondering if anyone has calculated the flow of their kit, it would save me a lot of math as I'm already doing quite a bit on this piece alone to see if it is feasible.

Guess I'll be the first! Actually shouldn't be TOO hard, just need to work with a couple of my engineering buddies who are fluid dynamics whizzes. Maybe I shoulda stayed in the engineering program with them...
