I got new injectors...what should I set my FPR to?
I am running the Giac J31 setup (MY 2k). It calls for stock injectors with 5 bars of fuel pressure.
I am upgrading to Ford motorsport "red top" 310cc injectors. (#30 I think). What should I set my fuel pressure to? I've heard anywhere from 3.6 bar to 3.8 bar.
Isn't there a mathematical equation to figure this out?

Here is the site that I use.
The stock 270cc at 5 bar = 33.19 lbs
So you want to set your fpr between 53 and 54 psi with the vacuum line pulled at idle. This will give you around 33.11 lbs and 33.43 lbs for your new 30 lbs injectors. I would start at 54 lbs and fine tune it from there.<ul><li><a href="http://www.rbracing-rsr.com/fuelinjectors.htm">http://www.rbracing-rsr.com/fuelinjectors.htm</a</li></ul>
