Went slower with N2O than N/A.

[99bird3.8]

Well, went to the track and I went slower with N2O than n/a. I am having a big sputtering issue because of my coils and it is making my car bog majorly. I didnt even break into the 14s, which I do N/A. Oh well, gotta get it tuned right, then I will hit the track again.

[12secondv6]

Well what happened?
I understand sputtering.
Do you have a check engine light on?
Was it the fpss?
Wet or dry kit?
ETC ETC ETC

[99bird3.8]

It was actually a combination of things. They way the nozzle was setup, the mix would hit the rubber acordion thingy and puddle up. Also, my coils are weak and not producing enough spark and not burning the mixture.

Let me ask you this....

When you started to sputter, did you continue to spray?

We talked on AIM last week and I told you not to mess around if its sputtering, why risk it?

Your saying you have a WET nozzel that is spraying from near the air box?

[xdamxincx]

hmm ur not giving enuf info on ur setup...
but i encountered the same symptom one day.. it turned out to be a plug wire..

The way the kit WAS setup, i had the nozzle before he maf. I know have it drilled into the throttle body. I just changed my spark plugs and wires. I now am changing the coils to see if they are too weak for it. I think having the nozzle before the maf, the maf picked up on the nitrous and sent more fuel. Since i am a wet shot, i already had fuel going in and my coils were not strong enough to burn all that fuel. I am going to try it again this Thursday when i get everything i ordered in.

[Magnus]

Ok, I ask again.....

You had bogging last week. Why CONTINUE to spray?
When you started to bog at the track, did you continue to spray? If so WHY?!

I remember telling you NOT to mess around with nitrous. You could have easily blew up your car. I know Mike Huff isn't too happy with his blown car and he knows what he's doing! Nitrous is volatile!

Maybe you were bogging cause you were spraying FUEL onto the MAF! Your MAF could be bad now.

I highly doubt you were bogging because your coil packs were weak. You would KNOW if they were weak.

[99bird3.8]

Well, i know the MAF isnt bad. I was running it at the track and I talked to Rich D, who's MAF went bad. He siad you can tell if it is bad because the car will idle really bad and the car will not stay on while idling. So I know it isnt bad. Coils can bexome weak under a hard load. YOu can run on weak coils n/a all you want, but when you put them under stress, then you can tell. That is what happened to Shane and he replaced it and that was all that needed to be done. Also, he has been spraying a wet shot before the maf for over a year now and he has had no problem except the coils.

SLOWER with nitrous?!
Must have been using those -75 shot pills in your jets...lol

just kidding. Sounds like what happend to me one time when i used my nitorus. Waht happend was the WOT switch for my nitorus was off, and was not being activated. Thus when the nitrous was sprayed, my engine was only recieving extra amount of fuel in the TB...= horrible bogging.

Check to see that the nitrous is spraying ok, and the selinoid isn't stuck closed.

If don't like to drill holes in the TB and spray AFTER the MAF, then sell your wet kit and buy a dry setup. I can't believe you sprayed fuel into the MAF. I doubt they work well wet. You could have damaged the MAF and then your car would have no clue what's going on as you sprayed it.

Don't use the coils as a scape goat either.

You expect a wet setup to work BEFORE the MAF? Is that what you expected? Just a yes or no question.

And you're saying that after you get new coils you're going to do it again?

[99bird3.8]

No, I went ahead and tapped it into my throttle body after the MAF. So now the MAf wont tell I have it. And the coils is to give me a better spark.

[Magnus]

Ok, I ask again.

You knew somethign wasn't right because it didn't pull like a raped ape at the track.. did you continue to spray? if so, why?

If you knew fuel was puddling in the intake tubing, why didn't that also signal you to not spray again?

Got that right, nitrous explosions are horrid and if you have fuel puddling up in the intake area that is like a stick of dynamite waiting to go off. Did you check the solenoids before spraying the car? I may have a nice dyno sheet but I'm still looking for toasted items from my backfire.

FYI, don't spray on the dyno untill at least 3500 rpms.

[99bird3.8]

I did not continue to spray after it sputtered. I checked the system out, and when I found otu about the puddling, I fixed the nozzle. I thought that was the problem. So I sprayed again and it did it again, so I stopped after that. That is when we found out that it is probably a weak coil. I already have NGK plugs and Taylor wires, so i know it wasnt them. I changed the nozzle to the throtle body, but I am waiting for the coils to come in before I try it again. The system works fine. I tested each solenoid seperately in the air to make sure they worked and were spraying right. I made sure I had the right jets. I went and ordered a fpss and n2o pressure guage to keep track of it all. I will have everything connected before I spray it again. I have been talking to alot of people who work with n2o and our cars and lt1 and ls1s. They say the only problem they can think about is the ignition. And Shane had his coils weak before and had the same problem. So we will find out on Thusrsday for everything. If not, I might convert it to dry and run it that way.
