purging out

is purging thru the motor at 3500 rpm ok i have been doing this for a few years.. or is dedicated purge solenoid and line needed.. my system is a dual stage n.o.s. setup with nitrous noids on a d block and fuel noids on a fuel log. so my thinking is that only purge one stage the other should be clear too.. also is fpss neededfor the fuel system and where to install it before reg. or after.

If you have been doing it a few years it must work! I have two systems and purge both systems at about 3500 – 3800.

i dont ever bang the engine .....just me

I always have purged on the motor.

In most cases we never use a fuel pressure safety switch. In many cases they seem to cause more issues then they are worth.. Thanks, SJ

X2 Do ya ever notice sometimes when ya hit the purge button ya hear the hiss but no nos visible then the 2nd push there it is the big white plume,I don't like the jab the pedal method for that reason you don't know if its full tilt or not and yes the motor will rev even if its not 100 % yet, i know everybody has there own method so this is jmo but i have tried it both ways, also i found the hardest hit is when i purge after the other guy stages i keep my finger on the button and watch his stage light then i purge and bump in i know some guys dislike staging 1st. but i won't budge its just what i'm use too, i had a few that said they hate that because once they stage their concentrating on that light and then the big hiss and big white plume next to them screws them up but thats their fault you should never let the other guy bother you its like the guys that play line games trying to get you on your converter for the full 10 seconds , if i'm running all motor then i could care less who stages 1st. but i still won't bring up the converter soon as i stage i do it soon as they stage.

Sorry but the only way is by doing both.....

Purge the system into the atmosphere is necessary to achieve the desired bottle pressure, especially with a few systems BUT

Banging through the motor is the only sure way to have absolutely zero air in the system. If you only purge into the atmosphere then your still leaving a gap from the solenoid to the plate/nozzles that may or may not be filled with N2O.

I've never seen any TS or Pro Mod guys purging into the air....

Then again I do things with my motor that people say can't be done

on the engine

well i wire up my system to purge to the atmosphere plus bang thru the motor with both stages im not at your level but still having fun. hope to run some 10s this year with a nothing build best on motor 11.51 @115 and with a 100hp hit 11.18 @126

You never seen any promod cars purging in the air i agree with it being crap from the solenoid to the plate/nozzles i just don't agree with motor purging only but hey everybody has there own ideas. I'd like to hear SJ's thought on this one seeing how he is the juice master

Why dont you change your avatar pic??BTW atmosphere purge is for pressure, bangin the motor is to get all the air out and clean off the plugs.

at the Rt 66 divisional there were several cars purging directly into the atmosphere and i didn't notice anyone bang it through the motor. That was in the fastest field of the year.
