what kind of fuel pressure should i see at the gauge??

Im having fuel issues with the nitrous and am checking the pressure before i adjust the safety switch,Im also running a 4# pulley,I am going to upgrade my fuel pump as soon as funds allow but i would like to use the juice in the mean time but dont want to grenade the motor.

Thanks Jerry

 

32 idle, low 40's pasrt throttle and 52 psi min at WOT.

 

thanks

 

 

If your having problems on the juce, you may need colder plugs. I was running TR'6s and now have TR'8s. Pinging when away as soon as I went with colder plugs!!!!
