Car falls on its face while launching off the line with nitrous on. No purge system.Is that maybe why? Car ran one time with nitrous on.Or could it be my stalk alternator? The tail lights dim when the car leaves with nitrous on.Please help!

 

Do you have a window switch? Did you ground the wires properly? Need more info....A nitrous system doesnt take much power no more than having your radio or your lights on. And what do you mean falls on its face? Hesitation? No Nitrous activation?

When nitrous systems fall on their face it is typically because either way too much fuel, or no spray.

I think you nitrous solenoid may not be opening right away. You may have an electrical issue that is causing this.

 

I wouldnt think it is an electrical problem. If the power comes on AFTER the hesistation, then you are not getting enough airflow through the intake at the point you begin to spray it. You need to make sure its not coming on before 3000rpms. A messed up tune can also cause that hesistation. If you have a CAI on your car, put the stock intake back on. My car used to do the same thing and after I got rid of the CAI it never did it again. Now the power just comes on smooth and strong.

Buy a window switch. They keep your engine safe and theyre just fun to drive with it. Without a window switch you kinda have to wait for 3000 rpms before you go WOT. But with one you can just drive it like normal. It comes on automatic and its so much better than just a WOT switch.

The first thing you should do is to check that both solenoids are working. Im sure you probably know how to do that.

If they are working then you have an A/F ratio problem or your spraying too soon.

Oh yea and I very much doubt its justv air in the line. Because air wont cause a very noticeable hesistation unless theres pretty much ALL air in the line which would only happen under rare circumstances.
