newbie to nitrous

[neubie50]

OK, don't flame me right off. My car just rolled over 100,000. I want to put a small hit of nitrous in it to give it a little more pull. I have intake, exhaust, plugs, wires, and soon to have the new slp rockers. I'm not asking what won't blow it up, i just don't wanna stress my 100,000 mi. engine to much. I've taken good care of it so i'm not to worried, just don't wanna over work the old girl. thanks.

I started out with a 85 shot, and went up to a 120 shot on a dry kit. Mine is on a '98 which has 82,000 miles on it. James (12sec) will tell you that no nitrous shot is "safe", so you gotta factor that in. These motors do hold up well.

Generally speaking, high revs are the thing that is the hardest on the bottom end.

**EDIT** also hitting at too low of an rpm is hard on the bottom end too, just like lugging an engine is hard on the bearings. Single stage nitrous flows the same amount all the time, even though the air flow into the engine is varying, so it is loading the cylinders with more nitrous at low rpms than it is at higher rpms. This is why manuals need a window switch. /**EDIT

Nitrous is harder on the top end. High cylinder pressures are developed which is hard on the head gaskets. Possible detonation is hard on ring lands and piston tops. Also if you go lean, cylinder temps go very high and the aluminum parts (i.e. cylinder tops) start melting and breaking. So the key is not to go lean, and not get detonation. Since I haven't heard of anyone running into detonation problems on here, the main focus would be on not running lean.

All the safety features (fpss, blowdown tube, etc.) are required if you want to keep things as safe as possible. Fuel pressure gauge is a good idea, but expensive. Some method of monitoring a/f (an a/f gauge, o2 voltmeter, autotap) is a very good idea too.

Very true, that is what I always say.

Could you handle it if there is damage to the engine?
If no then don't do it.

Now, if you want to juice the car I would suggest a full tune up.

NOS kit 5175 is a great easy beginner kit, 85 shot is what it starts at but you could get smaller jets, say a 50 hp shot.

Try a search for all the suggested safety equipement we have posted before.
