i bought a new kit back in 95 installed and pulled . install on a 96 ss same ploblem. turn on nos and when it comes in WOT. car acts like you reached up a turn off ingnition. NOS BOG the car down. WHAt is my PRoblem this kit did it brand new!! Fuel pump? it has power and can here it run.nos kit did this with 75hp nozzle . noew has 150hp noz.b/c of the 96 ss engine mods. still bogs!!!!!!!!!!!!

 

if it is a wet kit, did you put the pills in backwards? fuel pill in the nitrous side and vice versa.

if dry kit, where did you put the nozzle? before or after the MAF? for LT1 it goes after the MAF.

 

What is your bottle pressure and air fuel?
Dave

 

i had same problem and it could be your converter not letting your motor rev while its dumping extra fuel and nos...

or it could be your bottle pressure is not high enough

or you could have to much fuel...

 

Engine bogs, OR Turns OFF. The bog can be cause be alot of different items. Low bottle pressure, wrong jets, nitrous noid not turning on.

Turns OFF. Meaning nothing is happening, as if you turned the key off. If the car jumps and hauls *** after this little problem its fuel delivery to the injectors. Caused by week pump clogs fuel filter. When you turn your system on fuel psi goes down, until the lines are filled. Wet kits singlenozzles usually do not notice this, but if the fuel system is taxed it could be.

Can you give a little more info...

Ricky

 

This will happen if your nitrous comes on but there is no extra fuel being delivered,
or if there is extra fuel but no nitrous being delivered.

 

My guess is the same as everyone elses, to much fuel or not enough bottel pressure ......

There is not enough info here to know where to start..
Dave

 

just filled bottle . press has to br good. this has been a issue that i have let go on for years so i 'll have to recollect a little . i think i can remeber w/ a adjustable fuel reg. still can't get fuel press over 42-44 psi. so you maybe right about the solnoid, but i beleive it's lacking fuel. what is the best and cheapest fuel pump to try ? the nos one external must be no good? oh by the way it will not come out of the bog and haul ***,just a straight up bogggggggggggggggggggggggggggggggggg.

 

Ok so here is what I have been able to figure out so far..

It must be a dry NOS kit..
You had a full bottle but still do not know the bottle pressure.
You do not know aht air fuel is..

Ok here is where we are at...
First. Just because you have a fresh filled bottle it does not mean that the pressure is good.Pressure needs to be 950-1050 psi..

However with a dry kit even with bad bottle pressure the car should not bog.Unless there is just enough pressure to spike the regulater creating the fuel pressure to go up but not enough pressure to flow enough nitrous to even it out.. LONG shot.. I do not think that that is the problem.

It sound more like a fuel pressure problem. Do you have a fuel pressure gauge on the car? Have you looked at your plugs after making a pass?

What is done to your car mod wise.. Is your intank pump still stock?
Dave

 

Question of the year for you.
How many years have you been using a nitrous system on your car that does nothing but cause a bog?

I suppose there's a chance of some trash clogging the N2O jet or nozzle.

 

I have a NOS/Bosch inline fuel pump if ya need one. It's used but good, and you can have it for a song and dance. Let me know.

Robert56 you have mail
thanks,Johnny

 

yea stock intank pump. as for useing nos w/ bog for years, answer is I don't ,can't. it's just still on car w/ no use at all. yes it's adry kit and yes i've had a press gauge on it,like i said i haven't got it above 45psi as far as i remember.now let me say this. the blow off noz or over flow ,what ever it suppose to be, at the bottle is not on reason when i first tried to instal nos would come out that when valve was cracked. 2nd my adjust on the noid to try to gain press. is screwed out as far as possible with out falling off b/c of try to get press i needed as as far as i remember. it still wasn't close to what i needed. with yalls advise and ideas i was planning on trying to figure it out again so thanks for info so far ,maybe i can back trace and pay close att... to some thing to figure out or at least get you all better input. any way how can i detect air ratio,and for the mods to engine .portedand polished heads&iontake and cam with 1.6 roller rocks. don't even remember cam specs. right now ,no i don't drive car alot 96 ss 31,000 miles on the car.

 

still got that fuel pump? what it worth?

 

Any possible chance you could translate this into English?
We really do want to help, but I honestly can't make heads or tails of where you're at exactly.
You may need to contact the manufacturer of the kit or get with someone familiar with that type of kit to go over everything with you to make sure it's connected and working properly because it's obviously not working properly.

#1 The bottle has to be filled and positioned correctly in the car.
#2 You need a certain pressure in the bottle.
#3 The bottle must be turned on with no leaks.
#4 When activated the nitrous must flow out the nozzle and into the throttle body.
#5 Your system probably uses nitrous pressure to spike the fuel pressure regulator. If this isn't hooked up or doesn't work, then you get no extra fuel.

My first guess with the info provided so far is that #5 is the problem.

 

I agree on #5. Your FMU is faulty or incorrectly plumbed, or possibly your aux inline fuel pump is bad or wired incorrectly. Your pressure should be coming way up, but seems stuck at stock psi. If this is a NOS dry kit give them a call.
