Hi, can anyone could tell me what would be the damages in the engine of running lean or rich using nitrous?


could I know if I running lean or rich with a scanner?.

I have to take my car to someplace where i can find out what kind of CEL i got, I know is going to be a po134. but I dont know if this going to have to do with runnning lean or rich, or not.

What o2 sensor is the one with thte Air/fuel ratio? the first or the sencond?

thanks!

 

I am not too familier with the effects of Nitrous.. but the consequences of running way beyond Stoicimetric are well documented.

Lean cause engine detonation, which under the pressures of either boost or No2, will break piston rings, pistons, rods, and possibly blow the head off of your engine (exageration, you will probably loose the head gasket)

Rich is more insidious. Too much full can clog your cat through melt down due to the excess fuel being fired off by the heat of the cat. It can also wash down the oil from the cylinder walls and contaiminate your oil, which will slowly waste your engine bearings.

 

mmm..... sound very bad....

what sensor the the responsible of the A/F ratio? smile.gif

 

ohh the MAF right!.. but which one of the two o2 sensors?

the first one or the sencond one?

first. the seocnd is for emissions purposes only.

 

should be first one but only in closed loop (part throttle, idle, cruising).

second O2 should test how your catalityc cleans the air.

 

dont forget to mention all the effects of running too rich, (these may be obvious to most of us but hey), loss of power and loss of gas mileage, your not burning all the gas that enters your chamber. Its always better to be a little too rich than a little too lean because detonation is evil. hehe.

 

^^ sounds about right. better rich than lean. haha.

but with a wet system the lean is kind of hard right? or doesnt matter?

 

If everything is working properly (no fuel leaks, correct fuel nozzle, etc.) than you shouldn't run lean with nitrous. If something goes wrong (too small of a fuel nozzle for the nitrous, incorrectly teed off fuel line) then you will lean out with nitrous and you will go... how you say...

KABOOM.
