I switched to 16v and i bought the low pressure spring. My regulators on motor and my systems seem to be holding fine does the spring still need to be changed?
You drill the poppet in the bottom of the bypass the brass piece and i drill mine to 19/64 one size below 5/16 and told Magnafuel what i was doing and they told me it wouldn't work but 6 yrs later and 3 cars all done the same way spraying 3 and 4 foggers pump pressure always looked great on the Racepak. Before i did this it didnt look great at all on the graphs before the nitrous was applied but the spring may be better but a very well known nitrous racer and tuner does exactly the same thing.What exactly do you drill? Size?
