Nitrous fuel pressue info needed

Well at a 60 hit i don't think you will knock off those 4 tenths you're looking for...

As for fuel psi, i have always gone higher than recommended and like my results better than what they say should be.
I have always used between 12 and 16psi on a carb motor, i haven't lost, hurt, blown up a motor on n2o since 84, broke one crank on a 2stg 250 and 300 but since that only happened with the one crank it was a faulty crank, and it didn't really break till i took it out...you would think with a 375 base and 250 and 300 woulda made that crank do something bad other than make a noise i couldn't live with anymore.

I wouldn't even touch the timing till i ran it, in my motors i have found even with 5x your hit removing timing doesn't make it better or faster.
I have found that using large hits off idle does hammer bearings and you'll be changing them out sooner than you should, but that's it.

You can safely put 120 without even worrying following NX's advice
