has anyone had a problem with shooting 150 NX wet kit off the rail and the fuel pump .when my dad was going down the track w tr6 plugs he hit the n2o and the engine popped thru the exhaust
so we pulled all plugs they were ok we dont know what happened

 

Popping out the exhaust or through the intake? Did the car feel like it lost some power when you activated the system? If so there might not have been enough bottle pressure, too much fuel or like I've done a few times, forgot to open the bottle. A pop in the exhaust could be all the raw fuel inginting when it hits the heated O2 sensor. Just my own little thoery there though.

 

My Z pops through the exhaust even w/o N2O. Only after high rev and then letting off. Ive been told by all the motor heads its just back pressure not to worry about it.

 

thanks for all of your help i got the problem fixed the bottle didnt have enough press

 

through exhaust= too rich
through intake= too lean

 

I run a 150 shot with a walbro 255lph pump with no poping or any problems just smoth power all the way threw... with 900-1200 psi in the bottle. and a stock fpr. I have a brand new walbro 255lph pump f/s for 110 shipped if you want it email me ..
