boost ?
Assuming its do-able with numbers, Im looking for a math formula to determine max boost. If the centrifugal's output is 1850cfm, the engine is 555ci and the max rpm is 6500rpm, what is the boost at 6500?
Here is my best guess. operative word is guess. A 555 spinning 6500 rpm requires 1043cfm. ci / 2 X rpm / 1728 = cfm If you force an additional 807cfm into the motor, thats 77% more air over atmosphereic pressure (14.7). 14.7 X .77 = 11.32 psi boost. OK. Show me where I went wrong. Is it really this straight forward? |
