what is it about nitrous the makes it break stuff?
is it just increased cylinder pressures? or what?
i have the cam in my sig with some home ported heads (no numbers yet) and im looking to put a 150 rwhp shot on it and am curious if the bottom end will take it assuming a good tune.

Aside from tuning it correctly the extra cylinder pressure lifts heads, blows head gaskets, puts lots of stress on rods, bearings, etc...

i was under the impression that a 150 shot was pretty much standard on an LT1. and im not going to rely on a mail order tune. i plan on a dyno tune. im a little nervous about using nitrous and i want to take every precaution i can. i plan on buying a 6AL box at least, a WOT switch, and does it need to be put in before or after the MAF?

You should pull 4*of timing for every 50hp of nitrous. I use a WB and run 11.8 to 12.3 . Dont go to lean or you'll burn pistons and valves. And keep a small gap in your plugs .035" to .038", The cylinder pressure tends to blow the spark out and can cause miss fires ,and don't use any type of platinum plug.And use the right heat range plug for yours system. Its best to use some type of stainless steel head gasket to prevent blow out and after market head bolts or studs. or over 250 shot it good to O-ring your block. Use the matching jets and watch your nitrous pressure, if your pressure drops you will go rich and if pressure is to high you will go lean. But for me i watch my WB this tell me what i need to know. That's after i have all the above setup.

Well you explain to me what you would do. ??? I run wot 28* of timing NA ,and 18* on nitrous wot. And you gap your plugs on nitrous above .038" ? and run hotter plugs than stock ? And you run platinum plugs ? I know that you can run Iridium plugs. And if your nitrous pressure drops you wont go rich with your fuel pressure staying the same threw out the run. And my fuel to air set at 11.8 on nitrous and 12.8 NA. Ive been running nitrous for over 15 years and never and the first problem with it. And plus i said PULL (take out timing) not add timing, The Cometic head gaskets has a stainless steel core and so are the stock MLS
