Help with NOS Problems…

tuco · 09-11-2002, 07:35 PM

I have a 50hp / wet system, the NOS is activated at full open throttle.
Lately the power dose not come in smooth, it jerks back, it almost feels like I’m loosing power. (I have a pressure gage that measures the internal NOS pressure, and it stays constant). Could the NOS be pulling my timing off?
Has any one have this happened?

All suggestions are welcomed!

PS: can any one direct me where to view cool mustangs? I'm thinking about changing the hood on my stang, and I'll probably paint it, so I need to see some wicked ones....

do you hear any pinging at all when it does it?

It sounds like a possible fuel delivery problem, either too much or not enough, hopefully it is too much, cause not enough (lean) is dangerous.

do you have a fuel pressure gage that you can read while driving?

i agree sounds like fuel delivery take the car out and hit the nitrous just for a couple of seconds and then pull over and pull your plugs to check for fuel problems if they are really sooty black you are getting too much fuel and if they are blistery white you are running lean. let us know.

No pinging, but then again, ive never heard pinging before. My exaust is prety loud to even here the stereo.

thanks, I'll try that and let you know...
