fuel pressure for nitrous...

With all due respect, this is not helpful advice. This is not accurate.

That is the way I have always done it and it has always worked for me. I used 47n and 53f most of the time. I picked up at least 7 tenths in the 1/8 mile. 7.20's to 6.40's. It varied because of traction issues. 5.5 lbs fuel pressure.
