Re: N2O bogging? Need Advice! (twincam47)
Try activating at 3K (relatively safe on the bottom end - especially with a small shot).
Also, make sure to purge first. Without a puge kit, before you get to the track, with your bottle on, go full throttle and activate your unit until you feel it hit. You are now purged and ready to race.
The reason purging helps, is that when you turn the bottle on, air is in the nitrous side of the line in front of the nitrous. When you activate the unit, you get additional fuel from the fuel side of your unit, but instead of getting the nitrous to make the mixture perfect, you just get ordinary air for a moment or two - hence the bogg. When you purge, you will have nitrous pushing right up against your nitrous solenoid. Upon activation, the nitrous and fuel get released at the same time and in the proper ratio - result - no bogg.
Hope that helps.

Re: N2O bogging? Need Advice! (SilverStateZ06)
check the following things..
1. is the bottle open
2. is there power to the n20 solenoid.
bogging will happen when you spray only fuel into the manifold.

bottle opener is activating..........
hit the switch about 4 seperate times....Figured that would have purged the system.
Will double check N2O solenoid operation...Anything else come to mind?
Are the pea sizes OK....This was a used system for a 100 shot.

Turning on the bottle does not purge your system.
You have to get rid of the air that is in the line by activating the unit (unless you have a purge kit).
Oh, and your jetting is wrong. Here are some rough guidelines (ever setup is a little different). These numbers were found on LS1.com in the nitrous section - I don't know if they are accurate, but several posts confirmed these numbers - some setups were slightly leaner, but these are the safer numbers.
For a 50 shot:
35 nitrous and 20 fuel
For a 75 shot:
41 nitrous and 24 fuel
For a 100 shot:
52 nitrous and 33 fuel

Silverstate......If you are sure that the pea sizes are correct...Then that would account for the BOG.....The fuel and N2O lines are backwards from the solenoids to the spray nozzle......Can we verify this?

Re: N2O bogging? Need Advice! (twincam47)
VERY IMPORTANT!, did u change out the stock plugs? They are platnum(dont know how to spell it) and are about 2 steps too hot. Get some NGK TR6's gapped at bout .38 - .40(100hp shot). They seem to be the fav for N20 on this forum.
If u do have new plugs already and they are gapped good check the jet sizes to make shure they are not swapped like said earlier.

A 52 n2o and a 33 fuel would amount to about a 100 shot.
n2o (the brand) states that a 47 and 25 are a 100 shot.
However because you are pilled extremely rich (safe) it would probably amount to 100 instead of 115-120. (a 55 n2o pill is a 125)
Also you will have to have substantial pressure on the n2o side. Do you have a bottle heater? I run mine at about 1100 psi, but 900-1050 is what is recommended!
Pressure is importrant because if you run low pressure you will run into an overly rich condiditon, and vice versa for high pressure, overly lean.
Not running the right pressure (too low) will also cause you to bog tremendously.

n2o is a drug.....now yo u are addicted....when it all came down to it I decided that having a charger was cheaper. 300 bottles at 30 bucks per bottle = 9000.00....and I have all the receipts.
