Now that I have my alky psi readings on my XFI, I have a simple question.
I very slowly built some boost on the trans brake. I did a data log to see some basics. I wanted to study the actual initiation of the alky and how fast it ramps up against a slow boost increase. I noticed alky PSI begins to increase the same moment that boost begins to clime above 1 PSI. But until I reach 7 PSI of boost, the alky PSI does not overcome boost pressure. Then, of course, after that it increases exponentially.
Question...... This seems to me that the alky doesn't physically begin to spray from the nozzles until the boost pressure is overcome by the alky pressure. Correct? If both alky and boost PSI's are the same, nothing sprays.
In other words, no alky is entering the intake until after I hit 7 PSI of boost?
If so. That's fine. But it's nice to see and analyze the data and see the exact moments and begin to observe trends. This obviously makes recognizing a problem in the future easier.
