gotta love the compstars. 
Who has actually killed an engine with spray?
Sorry but I have to disagree. A turbo or a supercharger progressively increases power to the rotating assembly. With nitrous, unless you're using an electronic progressive controller you are hitting that rotating assembly all at once with that extra O2/nitrous and fuel increasing cylinder pressure driving that slug down the bore harder than normal.
Next time one of you nitrous guys pull your rod bearings look at the top half of it and you'll see the beating they take. Just my opinion. Remember I said it was 3rd in line so I'm not disagreeing with the tune.

You don't use stock bearings on any PA car you don't use stock rods or pushrods or springs wither. doesn't mean nitrous beats them up.
We have not killed a bearing yet on any of our cars with well over 2000 nitrous passes over 3-4 cars and 7 years with nitrous ls1's. We do have enough pistons and rings burned up to fill a kitchen trash can. We fd those up learning nitrous and never hurt a bearing. looking back 4 years we had some of the worst tuneups i can think of....
I blew my bolt on ls1 up, but it was driver error. I went thru 10+ bottles of a 75 shot with the car untuned and stuck in open loop and a 100k mile fuel filter and no fpss. The plugs came out white and green and rainbow. Piston 5 & 7 just had holes in the side about the size of a quarter.
Now a buddy of mine put a 160 shot on a bolt on LT1... but was a dumbass and forgot to take out the schrader valve so he wasnt getting any fuel. It actually took about 7 bottles to finally blow it up. pistion 3 was completly gone.
Always just move to bigger and better. He now has a built 383 and i now have a built 408. Its just an excuse to mod so spray the **** out of it and what happens happens.

That is the only way my wife will let me do rebuilds (without bitching incredibly) on my engines is if they blow. When they do I make the bottom end Freaking bullet proof. Once I rebuild this one I'll probably go with a D1 and the juice.

Thats the dumbest argument ever.

gotta respect people like yourself. i know i have read some place that nitrous is hard on the bearings, but i gotta believe and respect guys like you over someone with not so much experience. it's like my job, the engineers have a lot of theoretical knwledge, and we always butt heads, in the end field expierience always wins.

I couldn't ever get mine to give up. Went through a clutch,a six speed, and 2 axles. LOL. Ran my personal best with LT,ORY,GMMG, lid, ported TB, and 125 dry. Finally said to hell with it and took it apart so I could build it. LMAO!
Nitrous does blow up motors just not directly. The tune being off can and will kill a motor regardless if it is because it has too much timing, too much fuel or not enough fuel. But all the above conditions can occur on a perfect tune. Because of the nature of a nitrous system, there's just alot of stuff that can go wrong. Clogged lines, electrical shorts, sticking noids, poor bottle pressure, excessive bottle pressure, and leaks are the things that will usually take out a nitrous combo with a good tune.
