Well I was trying to spray this past weekend and the car made a loud pop noise and then bogged for a bit. Any causes that any one can think of. I'll be checking the whole setup to see if I can find any probs.

 

check everything that has to do with nitrous and fuel delivery. maybe due to installation

 

Are you using a wet kit? If so it could have been a backfire from fuel puddling in the intake manifold.

 

we need some details

 

It could be an empty bottle or what was previously stated, backfire.....backfore is bad.....if you got a dry kit then its probably empty.....check your plugs for detonation....

 

Sorry about no details guys. I have a NX Kit. Was working fine the last couple runs where my bottle was full. I had a couple of lbs left so decided to use it all up. But got a loud pop and then bogging. I was thinking even if I ran outa n2o it would just bogg didnt think it would backfire.

I've never had this prob on the DRY NOS kit I had. On the dry kit when outa n20 was just slow again. Never any weird backfired or popping noises.

Well my setup I/H/E and new plugs and wires with a VAFC. Plugs are gap at stock specs. The VAFC only settings change is the VTEC cross over.
