I have been thinking about NOS on my LS1 SS. I think you just made my mind up for me..thanks for the help, and sorry about the hot rod blow up.

Looks like a "lean" fuel mixture" backfire or they hit the engine on the rev limiter.

you're right about the backfire, but I doubt it's due to a lean condition... it's a wet-kit in the car, so for any nitrous added, the adequate gasoline will be added through the other solenoid.
There are 2 possibilities: 1. Bad installation: jetting sizes were not properly done and got fuel poddle in the manifold, causing the backfire. 2. Bad installation: no window-switch installed, causing the nitrous system not to stop before hitting the rev-limiter... when hitting the rev-limiter, the engine bogs, causing the backfire
Moral of the story... nitrous should be installed by pro... the same thing can be said with Turbos and S/C (please don't flame... my opinion)

I would REALLY like to know what happened, and if the motor lived. I want to see the A/F ratio right before it went. I bet it scared the sh*t out of the people standing there!!! Posts: 1443 | From: Lake Oswego, Oregon | Registered: Dec 2001

It's an old video....a guy who was actualy there, said that nothing happened to the engine....after replacing MAF and airbox, the car was ready to go...he didn't say why it happened...

When that happens, the air-lid goes as well as the MAF... and sometimes, a few things around it, depending on the intensity... but never major. In the other hand, if the engine goes lean... then, it's not nice... it basecally just lack of fuel, which can be caused by not strong enough fuel-pump, not high-flow enough injectors (on dry kits), solenoid that seized and does not deliver fuel (wet-kits), injector failure, etc... And when that happens... well, OUCH !!! + $$$
Nitrous ain't that bad if used properly... it's just cold air with high concentration of Oxygen, where you need to add more fuel to have a good mixture... it's the extra fuel that delivers the power, not the nitrous... the same with a S/C... you're pumping compressed air and need to increase the fuel through the injectors... if you lack fuel... same scenario... so people need to monitor fuel-pressure, boost level (S/C), nitrous pressure (N20), and so on.
The problems start occuring when people don't install things right, or start taking it to extremes... and in my book, that's not playing it smart. My 2 cents.
