sorry im new to the nitrous game. I got a 383 stroker that has an aftermarket carter mechanical fuel pump. Would i be safe running a 100-125 shot on a mechanical pump or should i go electronic.

Just as long as you have enough fuel pressure. I would say 8-9 psi should be good for no more than a 150 shot.

Enough fuel pressure, and drop a few degrees of timing? Why's that not good advice? I wouldn't be spraying hypereutectic pistons anyway.... [-X

8 or 9 psi will flood the carb for one.

What kind of fuel pressures are you guys running then? I run about 7.5 psi of fuel pressure and I don't have any trouble with pushing fuel through the needles??

i have hit 200 on them without a problem...and at least 20 bottles.what are your personal experiences on spraying on cast,hyperutectic,forged pistons??and not what you have read or what you were told.there is a guy on here whom i am friends with spraying 200 on his cast piston 454 and has been for a while now but its only 8.5.1 comp. and a large solid roller that bleeds off a lot cyl. pressure and runs 10.0..but his tune up is right on and has a kick *ss fuel system....

Only n2o I have played around with was a 200 shot on a 383 with a WOT setup on a buddies camaro. Bottom end was all forged and balanced, guy ran that combo for 5 years before he went to a 434 sbc with a direct port.
