RX7 460CC Injector Pressure
Hey folks. I did some searching around and didn't find an answer to my Q. I'm trying to scale my injectors in my AEM EMS, and I am currently running 1997 miata injectors. I went to the DIY wiki miata turbo page, and found that the stock injectors flow 254CC @ 3 Bar. I'm going to install some RX7 460cc injectors, p/n 195500-2010, but I need to know what the max flow is at X Bar to properly scale my fuel chart. Can anyone help with this?
Thanks!
Thanks!

The RX7 injectors are rated at ~3 bar just like most other injectors.
Here is a calculator that will give you an approximate answer for fuel flow through an injector after changing the fuel pressure: http://rceng.com/technical.aspx
(scroll down to "Find Fuel Flow After Pressure Change")
Assuming you're not changing pressure, just scale your table by Old Injector / New Injector.
FYI- the data I have seen says the 1990 Miata injector flows 230cc. Where did you find the 254cc number?
