I sprayed a couple of times yesterday. Each time, after I let off in third to slow down, there were several loud popping sounds (I think they came from the exhaust, but not sure). This doesn't usually happen, so I was wondering what it might have been. My system is set to run pretty rich while spraying, so was this just a regular backfire? I'm not too concerned, because the car seems to be running fine - however, like I said, it's never done this before.

Any feedback would be appreciated. Thanks.

exhaust leak is main cause


could be running rich also

Mine does the same thing after every nitrous run. My car goes rich for a second as soon as I let off so I pretty sure it's from all the unburnt fuel getting lit up in the exhaust.

Thanks, guys. Glad to know it's nothing to worry about.

I don't know if it will help but...after every run I shut down the juice while still at WOT and hold it at WOT for a second or two w/o the spray to clear things out a bit. I have never had so much as a hickup or backfire with running n20 for 4 years now, on a few different vehicles.

I had the saim thing only it can be a problem it blew my lid up. Only did it if i let all the way off all of a sudden. What i do know is let off slowly so the WOT switch closes but the nitrous in the intake clears. Itsa alot like helbents10 does.

Mine does it also, I will try to ht the switch off before letting off throttle, that should help.

Yeah, I was letting off all of a sudden. But, that's what I normally do, and it had never done this before. I'll try to get a couple runs in tonight and see if it still does it after I let off slowly. Thanks, guys.
