Hopefully I can explain this properly.
Looking for educated guess on pressure for part of fuel system.
80 a pump 6.78 gpm
main jet normaly 130 using 8 x.038 nozzles
cube enderle BV
With new system I would have 115 and 65(close numbers maybe not dead on) jets both low pressure poppets operating as one main jet.Would run system this way to get better dialed in before getting to next step.
the 65 jet would be bypass that in a valve of my design,should be free flowing for jet size.Under normal operation it would return to tank.Under nitrous use its enrichening system,jetting figured to be slightly more then the .065 bypass.This will be operating roughly within 500 rpm range 6500 to 7000. Real word testing will help zero in on exact range.
Not asking about nitrous just fuel pressure that would be on other side of the .065 jet at this rpm range. Oh yes this would be T'd in before BV and according to your calculator shouls have system pressure 93 psi. Not sure if enough info or if question can be answered w/o flow bench in even a SWAG. Not looking for dead on just good ballpark number. Mainly check calculation and fuel pressure flow for nitrous based on pressure. I have fomrulas to convert flows based on pressure and vice a versa if know one or the other.
Any idea? Sorry if hard to follow explanation.
